Config APIs
This section hosts the documentation for "unpublished" APIs which are used to
configure kubernetes components or tools. Most of these APIs are not exposed
by the API server in a RESTful way though they are essential for a user or an
operator to use or manage a cluster.
KYAML is essentially an output format; any place where you can provide KYAML to Kubernetes, you can also provide any other valid YAML input
YAML, available as a kubectl output format and also used at the HTTP layer
Kubernetes also has a custom protobuf encoding that is only used within HTTP messages.
The kubectl tool supports some other output formats, such as custom columns;
see output formats in the kubectl reference.
1 - Glossary
2 - API Overview
This section provides reference information for the Kubernetes API.
The REST API is the fundamental fabric of Kubernetes. All operations and
communications between components, and external user commands are REST API
calls that the API Server handles. Consequently, everything in the Kubernetes
platform is treated as an API object and has a corresponding entry in the
API.
The JSON and Protobuf serialization schemas follow the same guidelines for
schema changes. The following descriptions cover both formats.
The API versioning and software versioning are indirectly related.
The API and release versioning proposal
describes the relationship between API versioning and software versioning.
Different API versions indicate different levels of stability and support. You
can find more information about the criteria for each level in the
API Changes documentation.
Here's a summary of each level:
Alpha:
The version names contain alpha (for example, v1alpha1).
Built-in alpha API versions are disabled by default and must be explicitly enabled in the kube-apiserver configuration to be used.
The software may contain bugs. Enabling a feature may expose bugs.
Support for an alpha API may be dropped at any time without notice.
The API may change in incompatible ways in a later software release without notice.
The software is recommended for use only in short-lived testing clusters,
due to increased risk of bugs and lack of long-term support.
Beta:
The version names contain beta (for example, v2beta3).
Built-in beta API versions are disabled by default and must be explicitly enabled in the kube-apiserver configuration to be used
(except for beta versions of APIs introduced prior to Kubernetes 1.22, which were enabled by default).
Built-in beta API versions have a maximum lifetime of 9 months or 3 minor releases (whichever is longer) from introduction
to deprecation, and 9 months or 3 minor releases (whichever is longer) from deprecation to removal.
The software is well tested. Enabling a feature is considered safe.
The support for a feature will not be dropped, though the details may change.
The schema and/or semantics of objects may change in incompatible ways in
a subsequent beta or stable API version. When this happens, migration
instructions are provided. Adapting to a subsequent beta or stable API version
may require editing or re-creating API objects, and may not be straightforward.
The migration may require downtime for applications that rely on the feature.
The software is not recommended for production uses. Subsequent releases
may introduce incompatible changes. Use of beta API versions is
required to transition to subsequent beta or stable API versions
once the beta API version is deprecated and no longer served.
Note:
Please try beta features and provide feedback. After the features exit beta, it
may not be practical to make more changes.
Stable:
The version name is vX where X is an integer.
Stable API versions remain available for all future releases within a Kubernetes major version,
and there are no current plans for a major version revision of Kubernetes that removes stable APIs.
API groups
API groups
make it easier to extend the Kubernetes API.
The API group is specified in a REST path and in the apiVersion field of a
serialized object.
There are several API groups in Kubernetes:
The core (also called legacy) group is found at REST path /api/v1.
The core group is not specified as part of the apiVersion field, for
example, apiVersion: v1.
The named groups are at REST path /apis/$GROUP_NAME/$VERSION and use
apiVersion: $GROUP_NAME/$VERSION (for example, apiVersion: batch/v1).
You can find the full list of supported API groups in
Kubernetes API reference.
Enabling or disabling API groups
Certain resources and API groups are enabled by default. You can enable or
disable them by setting --runtime-config on the API server. The
--runtime-config flag accepts comma separated <key>[=<value>] pairs
describing the runtime configuration of the API server. If the =<value>
part is omitted, it is treated as if =true is specified. For example:
to disable batch/v1, set --runtime-config=batch/v1=false
to enable batch/v2alpha1, set --runtime-config=batch/v2alpha1
to enable a specific version of an API, such as storage.k8s.io/v1beta1/csistoragecapacities, set --runtime-config=storage.k8s.io/v1beta1/csistoragecapacities
Note:
When you enable or disable groups or resources, you need to restart the API
server and controller manager to pick up the --runtime-config changes.
Persistence
Kubernetes stores its serialized state in terms of the API resources by writing them into
etcd.
Kubernetes 1.36 includes optional declarative validation for APIs. When enabled, the Kubernetes API server can use this mechanism rather than the legacy approach that relies on hand-written Go
code (validation.go files) to ensure that requests against the API are valid.
Kubernetes developers, and people extending the Kubernetes API,
can define validation rules directly alongside the API type definitions (types.go files). Code authors define
special comment tags (e.g., +k8s:minimum=0). A code generator (validation-gen) then uses these tags to produce
optimized Go code for API validation.
While primarily a feature impacting Kubernetes contributors and potentially developers of extension API servers, cluster administrators should understand its behavior, especially during its rollout phases.
Declarative validation tags can apply directly to net-new API fields without requiring any lifecycle mechanism (for example, it is possible to use +k8s:minimum=1). For migrating existing hand-written validations where the declarative validation is shadowing the existing hand-written validation logic, the rollout is controlled by the validation lifecycle tags (+k8s:alpha and +k8s:beta) alongside the DeclarativeValidationBeta feature gate:
DeclarativeValidation: (GA in v1.36, Default: true, LockToDefault: true) The API server runs both the new declarative validation and the old hand-written validation for migrated types/fields in "shadow mode" (Alpha). The results are compared internally.
DeclarativeValidationBeta: (Beta, Default: true) Introduced in v1.36. This gate controls the enforcement of beta-stage validation rules. When enabled, rules marked as +k8s:beta are authoritative; when disabled, they revert to shadow mode.
DeclarativeValidationTakeover: (Deprecated in v1.36). Previously used to determine whether declarative validation results were authoritative. It is no longer honored but can still be set to prevent "gate not recognized" errors.
Default Behavior (Kubernetes 1.36):
With DeclarativeValidationBeta=true (the default), both validation systems run for Alpha and shadowed rules. Beta rules are enforced.
The results of the hand-written validation are used for Alpha rules. The declarative validation runs in a mismatch mode for comparison.
Mismatches between the two validation systems are logged by the API server and increment the declarative_validation_mismatch_total metric. This data allows contributors to identify and resolve discrepancies during the shadow phase.
Administrators can explicitly disable the DeclarativeValidationBeta feature gate to force +k8s:beta validation rules back into shadow mode if unexpected validation behavior or regressions are observed.
Disabling DeclarativeValidationBeta
As a cluster administrator, you might consider toggling DeclarativeValidationBeta=false under specific circumstances:
Unexpected Validation Behavior: If enabling DeclarativeValidationBeta leads to unexpected validation errors or allows objects that were previously invalid.
Performance Regressions: If monitoring indicates significant latency increases (e.g., in apiserver_request_duration_seconds) correlated with the feature's enablement.
High Mismatch Rate: If the declarative_validation_mismatch_total metric shows frequent mismatches, suggesting potential bugs in the declarative rules affecting the cluster's workloads, even if DeclarativeValidationBeta is false.
To revert +k8s:beta validation rules back to shadow mode, disable the DeclarativeValidationBeta feature gate, for example via command-line arguments: (--feature-gates=DeclarativeValidationBeta=false).
Considerations for downgrade and rollback
Disabling the DeclarativeValidationBeta feature gate acts as a safety mechanism. However, be aware of a potential edge case (considered unlikely due to extensive testing): If a bug in declarative validation (when DeclarativeValidationBeta=true) incorrectly allowed an invalid object to be persisted, disabling the feature gate might then cause subsequent updates to that specific object to be blocked by the now-authoritative (and correct) hand-written validation. Resolving this might require manual correction of the stored object, potentially via direct etcd modification in rare cases.
For details on managing feature gates, see Feature Gates.
Declarative validation tag reference
This document provides a comprehensive reference for all available declarative validation tags.
Indicates that this field is a member of a zero-or-one-of group.
Stable
Tag Reference
+k8s:alpha
Description:
The +k8s:alpha tag enables shadow mode for a validation rule. It represents the first phase of the validation lifecycle for safely migrating existing hand-written validation logic to declarative tags. Do not use this tag for net-new API fields, which should apply declarative validation tags directly.
When a validation is shadowed with +k8s:alpha, the validation logic executed includes the original hand-written
validation logic as it normally would but additionally runs the shadowed declarative validation in a non-blocking way,
and then verifies the results are matching.
Any mismatches or panics are recorded via metrics (for example: declarative_validation_mismatch_total and declarative_validation_panic_total).
This shadow mechanism enables contributors and administrators to evaluate declarative validation rules in a live environment without affecting cluster behavior. By monitoring the mismatch metrics, you can verify that the declarative rules behave identically to the existing hand-written logic before promoting the validation to beta.
Stability Level: Stable
Arguments:
since (string, required): The Kubernetes version in which the validation was first shadowed.
Payload:
<validation-tag>: The standard declarative validation tag to be shadowed (e.g., +k8s:minimum=1).
The +k8s:beta tag enables enforced mode for validation rules migrating from hand-written logic, controlled by the DeclarativeValidationBeta feature gate. Do not use this tag for net-new API fields, which should apply declarative validation tags directly.
After a validation rule has been evaluated in shadow mode (via +k8s:alpha), it is promoted to beta. When DeclarativeValidationBeta is enabled (the default), +k8s:beta rules are enforced and authoritative. Disabling the feature gate reverts +k8s:beta rules to shadow mode, providing a rollback mechanism if regressions occur.
Stability Level: Stable
Arguments:
since (string, required): The Kubernetes version in which the validation was promoted to beta.
Payload:
<validation-tag>: The standard declarative validation tag to be enforced (e.g., +k8s:minimum=1).
In this example, eachKey is used to specify that the +k8s:minimum tag should be applied to each int key in MyMap. This means that all keys in the map must be >= 1.
+k8s:eachVal
Description:
Declares a validation for each value in a map or list.
Stability Level: Alpha
Payload:
<validation-tag>: The tag to evaluate for each value.
In this example, eachVal is used to specify that the +k8s:minimum tag should be applied to each element in MyList. This means that all fields in MyStruct must be >= 1.
+k8s:enum
Description:
Indicates that a string type is an enum. All const values of this type are considered values in the enum.
Stability Level: Beta
Usage Example:
First, define a new string type and some constants of that type:
In this example, MyField is required only if the "my-feature" option is enabled.
+k8s:isSubresource
Stability Level: Stable
Description:
The +k8s:isSubresource tag is a package-level comment that scopes the validation rules within that package to a specific subresource. It essentially tells the code generator, "The validation logic defined here is the specific implementation for this subresource and should not be applied to the root object or any other subresource."
CRITICAL DEPENDENCY:
This tag is dependent on a corresponding +k8s:supportsSubresource tag being present in the package where the main API type is defined.
+k8s:supportsSubresource opens the door by telling the dispatcher that a subresource is valid.
+k8s:isSubresource provides the specialized validation logic that runs when a request comes through that door.
If you use +k8s:isSubresource without the corresponding +k8s:supportsSubresource declaration on the main type, the specialized validation code will be generated but will be unreachable. The main dispatcher will not recognize the subresource path and will reject the request before it can be routed to your specific validation logic.
This dependency allows for powerful organization, such as placing your main API types in one package and defining their subresource-specific validations in separate, dedicated packages.
Scope: Package
Payload:
<subresource-path>: The path of the subresource to which the validations in this package should apply (e.g., "/status", "/scale").
Usage Example:
This two-part example demonstrates the intended use case of separating concerns.
1. Declare Support in the Main API Package:
First, declare that the Deployment type supports /scale validation in its primary package.
File: staging/src/k8s.io/api/apps/v1/doc.go
// This enables the validation dispatcher to handle requests for "/scale".// +k8s:supportsSubresource="/scale"packagev1// ... includes the definition for the Deployment type
2. Scope Validation Logic in a Separate Package:
Next, create a separate package for the validation rules that are specific only to the /scale subresource.
// This ensures the rules in this package ONLY run for the "/scale" subresource.// +k8s:isSubresource="/scale"packagescaleimport"k8s.io/api/apps/v1"// Validation code in this package would reference types from package v1 (e.g., v1.Scale).// The generated validation function will only be invoked for requests to the "/scale"// subresource of a type defined in a package that supports it.
+k8s:item
Description:
Declares a validation for an item of a slice declared as a +k8s:listType=map. The item to match is declared by providing field-value pair arguments where the field is a listMapKey. All listMapKey key fields must be specified.
The condition with type "Approved" is part of a zero-or-one-of group.
The condition with type "Denied" is part of a zero-or-one-of group.
+k8s:listMapKey
Description:
Declares a named sub-field of a list's value-type to be part of the list-map key. This tag is required when +k8s:listType=map is used. Multiple +k8s:listMapKey tags can be used on a list-map to specify that it is keyed off of multiple fields.
Stability Level: Stable
Payload:
<field-json-name>: The JSON name of the field to be used as the key.
In this example, MyList is declared as a list of type map, with keyField as the key. This means that the validation logic will ensure that each element in the list has a unique keyField.
+k8s:maxItems
Description:
Indicates that a list field has a limit on its size.
Stability Level: Stable
Payload:
<non-negative integer>: This field must be no more than X items long.
Indicates that any validations declared on the referenced type will be ignored. If a referenced type's package is not included in the generator's current flags, this tag must be set, or code generation will fail (preventing silent mistakes). If the validations should not be ignored, add the type's package to the generator using the --readonly-pkg flag.
In this example, MySubfield within MyStruct is required.
+k8s:supportsSubresource
Stability Level: Stable
Description:
The +k8s:supportsSubresource tag is a package-level comment tag that declares which subresources are valid targets for validation for the types within that package. Think of this tag as registering an endpoint; it tells the validation framework that a specific subresource path is recognized and should not be immediately rejected.
When the validation code is generated, this tag adds the specified subresource path to the main dispatch function for a type. This allows incoming requests for that subresource to be routed to a validation implementation.
Multiple tags can be used to declare support for several subresources. If no +k8s:supportsSubresource tags are present in a package, validation is only enabled for the root resource (e.g., .../myresources/myobject), and any requests to subresources will fail with a "no validation found" error.
Standalone Usage:
If you use +k8s:supportsSubresource without a corresponding +k8s:isSubresource tag for a specific validation, the validation rules for the root object will be applied to the subresource by default.
Scope: Package
Payload:
<subresource-path>: The path of the subresource to support (e.g., "/status", "/scale").
Usage Example:
By adding these tags, you are enabling the validation system to handle requests for the /status and /scale subresources for the types defined in package v1.
In this example, the Type field is the discriminator for the union. The value of Type will determine which of the union members (M1 or M2) is expected to be present.
+k8s:unionMember
Description:
Indicates that this field is a member of a union.
Stability Level: Stable
Arguments:
union (string, optional): The name of the union, if more than one exists.
memberName (string, optional): The discriminator value for this member. Defaults to the field's name.
In this example, M1 and M2 are members of the named union union1.
+k8s:zeroOrOneOfMember
Description:
Indicates that this field is a member of a zero-or-one-of union. A zero-or-one-of union allows at most one member to be set. Unlike regular unions, having no members set is valid.
Stability Level: Stable
Arguments:
union (string, optional): The name of the union, if more than one exists.
memberName (string, optional): The custom member name for this member. Defaults to the field's name.
In this example, at most one of A or B can be set. It is also valid for neither to be set.
2.2 - Kubernetes API Concepts
The Kubernetes API is a resource-based (RESTful) programmatic interface
provided via HTTP. It supports retrieving, creating, updating, and deleting
primary resources via the standard HTTP verbs (POST, PUT, PATCH, DELETE,
GET).
For some resources, the API includes additional subresources that allow
fine-grained authorization (such as separate views for Pod details and
log retrievals), and can accept and serve those resources in different
representations for convenience or efficiency.
Kubernetes supports efficient change notifications on resources via
watches:
in the Kubernetes API, watch is a verb that is used to track changes to an object in Kubernetes as a stream.
It is used for the efficient detection of changes.
Kubernetes also provides consistent list operations so that API clients can
effectively cache, track, and synchronize the state of resources.
You can view the API reference online,
or read on to learn about the API in general.
Kubernetes API terminology
Kubernetes generally leverages common RESTful terminology to describe the
API concepts:
A resource type is the name used in the URL (pods, namespaces, services)
All resource types have a concrete representation (their object schema) which is called a kind
A list of instances of a resource type is known as a collection
A single instance of a resource type is called a resource, and also usually represents an object
For some resource types, the API includes one or more sub-resources, which are represented as URI paths below the resource
Most Kubernetes API resource types are
objects –
they represent a concrete instance of a concept on the cluster, like a
pod or namespace. A smaller number of API resource types are virtual in
that they often represent operations on objects, rather than objects, such
as a permission check
(use a POST with a JSON-encoded body of SubjectAccessReview to the
subjectaccessreviews resource), or the eviction sub-resource of a Pod
(used to trigger
API-initiated eviction).
Object names
All objects you can create via the API have a unique object
name to allow idempotent creation and
retrieval, except that virtual resource types may not have unique names if they are
not retrievable, or do not rely on idempotency.
Within a namespace, an object's
unique identity is defined by the tuple of its API Group, Resource,
Namespace, and Name.
Cross-Group: You can have two objects with the same name if they belong to
different API Groups (for example, apps vs. example.com).
Cross-Version: Different API Versions (such as v1 and v1beta1) of the
same Group and Resource represent the same underlying data. Creating an object
with the same name in a different version of the same group results in a name
clash, as they share the same identity in storage.
Some objects are not namespaced (for example: Nodes), and so their names must
be unique across the whole cluster.
API verbs
Almost all object resource types support the standard HTTP verbs - GET, POST, PUT, PATCH,
and DELETE. Kubernetes also uses its own verbs, which are often written in lowercase to distinguish
them from HTTP verbs.
Kubernetes uses the term list to describe the action of returning a collection of
resources, to distinguish it from retrieving a single resource which is usually called
a get. If you sent an HTTP GET request with the ?watch query parameter,
Kubernetes calls this a watch and not a get
(see Efficient detection of changes for more details).
For PUT requests, Kubernetes internally classifies these as either create or update
based on the state of the existing object. An update is different from a patch; the
HTTP verb for a patch is PATCH.
Resource URIs
All resource types are either scoped by the cluster (/apis/GROUP/VERSION/*) or to a
namespace (/apis/GROUP/VERSION/namespaces/NAMESPACE/*). A namespace-scoped resource
type will be deleted when its namespace is deleted and access to that resource type
is controlled by authorization checks on the namespace scope.
Note: core resources use /api instead of /apis and omit the GROUP path segment.
You can also access collections of resources (for example: listing all Nodes).
The following paths are used to retrieve collections and resources:
Cluster-scoped resources:
GET /apis/GROUP/VERSION/RESOURCETYPE - return the collection of resources of the resource type
GET /apis/GROUP/VERSION/RESOURCETYPE/NAME - return the resource with NAME under the resource type
Namespace-scoped resources:
GET /apis/GROUP/VERSION/RESOURCETYPE - return the collection of all
instances of the resource type across all namespaces
GET /apis/GROUP/VERSION/namespaces/NAMESPACE/RESOURCETYPE - return
collection of all instances of the resource type in NAMESPACE
GET /apis/GROUP/VERSION/namespaces/NAMESPACE/RESOURCETYPE/NAME -
return the instance of the resource type with NAME in NAMESPACE
Since a namespace is a cluster-scoped resource type, you can retrieve the list
(“collection”) of all namespaces with GET /api/v1/namespaces and details about
a particular namespace with GET /api/v1/namespaces/NAME.
Cluster-scoped subresource: GET /apis/GROUP/VERSION/RESOURCETYPE/NAME/SUBRESOURCE
Namespace-scoped subresource: GET /apis/GROUP/VERSION/namespaces/NAMESPACE/RESOURCETYPE/NAME/SUBRESOURCE
The verbs supported for each subresource will differ depending on the object -
see the API reference for more information. It
is not possible to access sub-resources across multiple resources - generally a new
virtual resource type would be used if that becomes necessary.
HTTP media types
Over HTTP, Kubernetes supports JSON, YAML, CBOR and Protobuf wire encodings.
By default, Kubernetes returns objects in JSON serialization, using the
application/json media type. Although JSON is the default, clients may request a response in
YAML, or use the more efficient binary Protobuf representation for better performance at scale.
The Kubernetes API implements standard HTTP content type negotiation: passing an
Accept header with a GET call will request that the server tries to return
a response in your preferred media type. If you want to send an object in Protobuf to
the server for a PUT or POST request, you must set the Content-Type request header
appropriately.
If you request an available media type, the API server returns a response with a suitable
Content-Type; if none of the media types you request are supported, the API server returns
a 406 Not acceptable error message.
All built-in resource types support the application/json media type.
Chunked encoding of collections
For JSON and Protobuf encoding, Kubernetes implements custom encoders that write item, by item.
The feature doesn't change the output, but allows API server to avoid loading whole LIST response into memory.
Using other types of encoding (including pretty representation of JSON)
should be avoided for large collections of resources (>100MB) as it can have negative performance impact.
JSON resource encoding
The Kubernetes API defaults to using JSON for encoding
HTTP message bodies.
For example:
List all of the pods on a cluster, without specifying a preferred format
GET /api/v1/pods
200 OK
Content-Type: application/json
… JSON encoded collection of Pods (PodList object)
Create a pod by sending JSON to the server, requesting a JSON response.
POST /api/v1/namespaces/test/pods
Content-Type: application/json
Accept: application/json
… JSON encoded Pod object
You can also request table and metadata-only
representations of this encoding.
YAML resource encoding
Kubernetes also supports the application/yaml
media type for both requests and responses. YAML
can be used for defining Kubernetes manifests and API interactions.
For example:
List all of the pods on a cluster in YAML format
GET /api/v1/pods
Accept: application/yaml
200 OK
Content-Type: application/yaml
… YAML encoded collection of Pods (PodList object)
Create a pod by sending YAML-encoded data to the server, requesting a YAML response:
POST /api/v1/namespaces/test/pods
Content-Type: application/yaml
Accept: application/yaml
… YAML encoded Pod object
200 OK
Content-Type: application/yaml
apiVersion: v1
kind: Pod
metadata:
name: my-pod
…
You can also request table and metadata-only
representations of this encoding.
Kubernetes Protobuf encoding
Kubernetes uses an envelope wrapper to encode Protobuf responses.
That wrapper starts with a 4 byte magic number to help identify content in disk or in etcd as Protobuf
(as opposed to JSON). The 4 byte magic number data is followed by a Protobuf encoded wrapper message, which
describes the encoding and type of the underlying object. Within the Protobuf wrapper message,
the inner object data is recorded using the raw field of Unknown (see the IDL
for more detail).
For example:
List all of the pods on a cluster in Protobuf format.
GET /api/v1/pods
Accept: application/vnd.kubernetes.protobuf
200 OK
Content-Type: application/vnd.kubernetes.protobuf
… binary encoded collection of Pods (PodList object)
Create a pod by sending Protobuf encoded data to the server, but request a response
in JSON.
POST /api/v1/namespaces/test/pods
Content-Type: application/vnd.kubernetes.protobuf
Accept: application/json
… binary encoded Pod object
You can use both techniques together and use Kubernetes' Protobuf encoding to interact with any API that
supports it, for both reads and writes. Only some API resource types are compatible
with Protobuf.
Not all API resource types support Kubernetes' Protobuf encoding; specifically, Protobuf isn't
available for resources that are defined as
CustomResourceDefinitions
or are served via the
aggregation layer.
As a client, if you might need to work with extension types you should specify multiple
content types in the request Accept header to support fallback to JSON.
For example:
FEATURE STATE:Kubernetes v1.32 [alpha](disabled by default)
With the CBORServingAndStoragefeature gate
enabled, request and response bodies for all built-in resource types and all resources defined by a
CustomResourceDefinition may be encoded to the
CBOR binary data format. CBOR is also supported at the
aggregation layer if it is enabled in
individual aggregated API servers.
Clients should indicate the IANA media type application/cbor in the Content-Type HTTP request
header when the request body contains a single CBOR
encoded data item, and in the Accept HTTP request
header when prepared to accept a CBOR encoded data item in the response. API servers will use
application/cbor in the Content-Type HTTP response header when the response body contains a
CBOR-encoded object.
If an API server encodes its response to a watch request using
CBOR, the response body will be a CBOR Sequence and the
Content-Type HTTP response header will use the IANA media type application/cbor-seq. Each entry
of the sequence (if any) is a single CBOR-encoded watch event.
In addition to the existing application/apply-patch+yaml media type for YAML-encoded
server-side apply configurations, API servers that enable CBOR will accept the
application/apply-patch+cbor media type for CBOR-encoded server-side apply configurations. There
is no supported CBOR equivalent for application/json-patch+json or application/merge-patch+json,
or application/strategic-merge-patch+json.
You can also request table and metadata-only
representations of this encoding.
Efficient detection of changes
The Kubernetes API allows clients to make an initial request for an object or a
collection, and then to track changes since that initial request: a watch. Clients
can send a list or a get and then make a follow-up watch request.
To make this change tracking possible, every Kubernetes object has a resourceVersion
field representing the version of that resource as stored in the underlying persistence
layer. When retrieving a collection of resources (either namespace or cluster scoped),
the response from the API server contains a resourceVersion value. The client can
use that resourceVersion to initiate a watch against the API server.
When you send a watch request, the API server responds with a stream of
changes. These changes itemize the outcome of operations (such as create, delete,
and update) that occurred after the resourceVersion you specified as a parameter
to the watch request. The overall watch mechanism allows a client to fetch
the current state and then subscribe to subsequent changes, without missing any events.
If a client watch is disconnected then that client can start a new watch from
the last returned resourceVersion; the client could also perform a fresh get /
list request and begin again. See Resource Version Semantics
for more detail.
For example:
List all of the pods in a given namespace.
GET /api/v1/namespaces/test/pods
---
200 OK
Content-Type: application/json
{
"kind": "PodList",
"apiVersion": "v1",
"metadata": {"resourceVersion":"10245"},
"items": [...]
}
Starting from resource version 10245, receive notifications of any API operations
(such as create, delete, patch or update) that affect Pods in the
test namespace. Each change notification is a JSON document. The HTTP response body
(served as application/json) consists a series of JSON documents.
A given Kubernetes server will only preserve a historical record of changes for a
limited time. Clusters using etcd 3 preserve changes in the last 5 minutes by default.
When the requested watch operations fail because the historical version of that
resource is not available, clients must handle the case by recognizing the status code
410 Gone, clearing their local cache, performing a new get or list operation,
and starting the watch from the resourceVersion that was returned.
For subscribing to collections, Kubernetes client libraries typically offer some form
of standard tool for this list-then-watch logic. (In the Go client library,
this is called a Reflector and is located in the k8s.io/client-go/tools/cache package.)
Watch bookmarks
To mitigate the impact of short history window, the Kubernetes API provides a watch
event named BOOKMARK. It is a special kind of event to mark that all changes up
to a given resourceVersion the client is requesting have already been sent. The
document representing the BOOKMARK event is of the type requested by the request,
but only includes a .metadata.resourceVersion field. For example:
As a client, you can request BOOKMARK events by setting the
allowWatchBookmarks=true query parameter to a watch request, but you shouldn't
assume bookmarks are returned at any specific interval, nor can clients assume that
the API server will send any BOOKMARK event even when requested.
Streaming lists
FEATURE STATE:Kubernetes v1.34 [beta](enabled by default)
On large clusters, retrieving the collection of some resource types may result in
a significant increase of resource usage (primarily RAM) on the control plane.
To alleviate the impact and simplify the user experience of the list + watch
pattern, Kubernetes v1.32 promotes to beta the feature that allows requesting the initial state
(previously requested via the list request) as part of the watch request.
On the client-side the initial state can be requested by specifying sendInitialEvents=true as query string parameter
in a watch request. If set, the API server starts the watch stream with synthetic init
events (of type ADDED) to build the whole state of all existing objects followed by a
BOOKMARK event
(if requested via allowWatchBookmarks=true option). The bookmark event includes the resource version
to which is synced. After sending the bookmark event, the API server continues as for any other watch
request.
When you set sendInitialEvents=true in the query string, Kubernetes also requires that you set
resourceVersionMatch to NotOlderThan value.
If you provided resourceVersion in the query string without providing a value or don't provide
it at all, this is interpreted as a request for consistent read;
the bookmark event is sent when the state is synced at least to the moment of a consistent read
from when the request started to be processed. If you specify resourceVersion (in the query string),
the bookmark event is sent when the state is synced at least to the provided resource version.
Example
An example: you want to watch a collection of Pods. For that collection, the current resource version
is 10245 and there are two pods: foo and bar. Then sending the following request (explicitly requesting
consistent read by setting empty resource version using resourceVersion=) could result
in the following sequence of events:
FEATURE STATE:Kubernetes v1.36 [alpha](disabled by default)
On large clusters, controllers that watch high-cardinality resource types (such as Pods
or Endpoints) may consume significant network bandwidth and CPU by receiving and
deserializing the full event stream, even when they only need a subset of objects.
Sharded list and watch allows horizontally scaled controllers to split the workload
so that each replica only receives the events it is responsible for.
Kubernetes 1.36 introduces an alpha feature that allows clients
to request a filtered shard of objects from the API server, using hash-based
partitioning on metadata fields. To use this feature, enable the ShardedListAndWatchfeature gate on the
API server. When enabled, the API server filters both list responses and watch event
streams server-side, delivering only the objects and events whose hashed metadata value
falls within the requested range.
The shardSelector field
The ShardSelector field on
ListOptions
accepts a CEL-based expression using the shardRange() function:
<field-path> is the metadata field to hash, using CEL-style object-rooted syntax.
Currently supported paths are:
object.metadata.uid
object.metadata.namespace
<hex-start> is the inclusive lower bound of the hash range, as a 0x-prefixed
16-digit lowercase hex string (for example, '0x0000000000000000').
<hex-end> is the exclusive upper bound, as a 0x-prefixed hex string. The maximum
value is '0x10000000000000000' (2^64).
The API server computes a deterministic 64-bit
FNV-1a
hash of the specified field value and returns only objects whose hash falls within the
range [start, end). The hash function produces the same result for the same input
across all API server instances, so sharded requests are safe to use with multiple
API server replicas.
You can combine multiple ranges with || (logical OR) to cover non-contiguous parts of
the hash space. All ranges in a single expression must use the same field path.
Using sharded list and watch in controllers
Controllers typically use informers
to list and watch resources. To shard the workload across replicas, each replica
injects the ShardSelector field into the ListOptions used by its informers.
The standard way to do this is with WithTweakListOptions when constructing a
shared informer factory. The tweak function runs before every list and watch call
the informer makes, so the shard selector is applied consistently:
import(metav1"k8s.io/apimachinery/pkg/apis/meta/v1""k8s.io/client-go/informers")// shardSelector is determined by the replica's identity (e.g. from a// StatefulSet ordinal or lease-based assignment). Each replica claims a// non-overlapping range of the hash space.shardSelector:="shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000')"factory:=informers.NewSharedInformerFactoryWithOptions(client,resyncPeriod,informers.WithTweakListOptions(func(opts*metav1.ListOptions){opts.ShardSelector=shardSelector}),)
With this configuration, every informer created from the factory only lists and
watches objects whose hashed UID falls within the assigned range. Each replica
receives a disjoint subset of the full collection, reducing per-replica network
traffic and memory usage.
For a 2-replica deployment, the selectors would be:
// Replica 0: lower half of the hash space"shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000')"// Replica 1: upper half of the hash space"shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000')"
A single replica can also handle non-contiguous ranges using ||:
When the API server honors a ShardSelector, the list response includes a shardInfo
field in the list metadata. This echoes back the selector so clients can verify which
shard they received. For watch streams, the shard selector applies equally: the API
server only sends events for objects whose hash falls within the requested range.
A list response that contains shardInfo represents a filtered subset of the full
collection. Clients should not treat sharded list responses as a complete representation
of the resource type.
Detecting server support
If the API server does not support sharded list and watch (because the feature gate is
not enabled, or the server is an older version), the ShardSelector field is ignored
and the server returns the full, unfiltered result set. Clients can detect this by
checking for the presence of shardInfo in the list response metadata. If shardInfo
is absent, the server did not honor the shard selector and the client received the
complete, unfiltered collection. In this case, the client should be prepared to handle
the full result set, for example by applying client-side filtering to discard objects
outside its assigned shard range.
Response compression
FEATURE STATE:Kubernetes v1.16 [beta](enabled by default)
APIResponseCompression is an option that allows the API server to compress the responses for get
and list requests, reducing the network bandwidth and improving the performance of large-scale clusters.
It is enabled by default since Kubernetes 1.16 and it can be disabled by including
APIResponseCompression=false in the --feature-gates flag on the API server.
API response compression can significantly reduce the size of the response, especially for large resources or
collections.
For example, a list request for pods can return hundreds of kilobytes or even megabytes of data,
depending on the number of pods and their attributes. By compressing the response, the network bandwidth
can be saved and the latency can be reduced.
To verify if APIResponseCompression is working, you can send a get or list request to the
API server with an Accept-Encoding header, and check the response size and headers. For example:
GET /api/v1/pods
Accept-Encoding: gzip
---
200 OK
Content-Type: application/json
content-encoding: gzip
...
The content-encoding header indicates that the response is compressed with gzip.
Retrieving large results sets in chunks
FEATURE STATE:Kubernetes v1.29 [stable](enabled by default)
On large clusters, retrieving the collection of some resource types may result in
very large responses that can impact the server and client. For instance, a cluster
may have tens of thousands of Pods, each of which is equivalent to roughly 2 KiB of
encoded JSON. Retrieving all pods across all namespaces may result in a very large
response (10-20MB) and consume a large amount of server resources.
The Kubernetes API server supports the ability to break a single large collection request
into many smaller chunks while preserving the consistency of the total request. Each
chunk can be returned sequentially which reduces both the total size of the request and
allows user-oriented clients to display results incrementally to improve responsiveness.
You can request that the API server handles a list by serving single collection
using pages (which Kubernetes calls chunks). To retrieve a single collection in
chunks, two query parameters limit and continue are supported on requests against
collections, and a response field continue is returned from all list operations
in the collection's metadata field. A client should specify the maximum results they
wish to receive in each chunk with limit and the server will return up to limit
resources in the result and include a continue value if there are more resources
in the collection.
As an API client, you can then pass this continue value to the API server on the
next request, to instruct the server to return the next page (chunk) of results. By
continuing until the server returns an empty continue value, you can retrieve the
entire collection.
Like a watch operation, a continue token will expire after a short amount
of time (by default 5 minutes) and return a 410 Gone if more results cannot be
returned. In this case, the client will need to start from the beginning or omit the
limit parameter.
For example, if there are 1,253 pods on the cluster and you want to receive chunks
of 500 pods at a time, request those chunks as follows:
List all of the pods on a cluster, retrieving up to 500 pods each time.
Continue the previous call, retrieving the last 253 pods.
GET /api/v1/pods?limit=500&continue=ENCODED_CONTINUE_TOKEN_2
---
200 OK
Content-Type: application/json
{
"kind": "PodList",
"apiVersion": "v1",
"metadata": {
"resourceVersion":"10245",
"continue": "", // continue token is empty because we have reached the end of the list
...
},
"items": [...] // returns pods 1001-1253
}
Notice that the resourceVersion of the collection remains constant across each request,
indicating the server is showing you a consistent snapshot of the pods. Pods that
are created, updated, or deleted after version 10245 would not be shown unless
you make a separate list request without the continue token. This allows you
to break large requests into smaller chunks and then perform a watch operation
on the full set without missing any updates.
remainingItemCount is the number of subsequent items in the collection that are not
included in this response. If the list request contained label or field
selectors then the number of
remaining items is unknown and the API server does not include a remainingItemCount
field in its response.
If the list is complete (either because it is not chunking, or because this is the
last chunk), then there are no more remaining items and the API server does not include a
remainingItemCount field in its response. The intended use of the remainingItemCount
is estimating the size of a collection.
Collections
In Kubernetes terminology, the response you get from a list is
a collection. However, Kubernetes defines concrete kinds for
collections of different types of resource. Collections have a kind
named for the resource kind, with List appended.
When you query the API for a particular type, all items returned by that query are
of that type. For example, when you list Services, the collection response
has kind set to
ServiceList;
each item in that collection represents a single Service. For example:
There are dozens of collection types (such as PodList, ServiceList,
and NodeList) defined in the Kubernetes API.
You can get more information about each collection type from the
Kubernetes API documentation.
Some tools, such as kubectl, represent the Kubernetes collection
mechanism slightly differently from the Kubernetes API itself.
Because the output of kubectl might include the response from
multiple list operations at the API level, kubectl represents
a list of items using kind: List. For example:
Keep in mind that the Kubernetes API does not have a kind named List.
kind: List is a client-side, internal implementation detail for processing
collections that might be of different kinds of object. Avoid depending on
kind: List in automation or other code.
Table fetches
When you run kubectl get, the default output format is a simple tabular
representation of one or more instances of a particular resource type. In the past,
clients were required to reproduce the tabular and describe output implemented in
kubectl to perform simple lists of objects.
A few limitations of that approach include non-trivial logic when dealing with
certain objects. Additionally, types provided by API aggregation or third party
resources are not known at compile time. This means that generic implementations
had to be in place for types unrecognized by a client.
In order to avoid potential limitations as described above, clients may request
the Table representation of objects, delegating specific details of printing to the
server. The Kubernetes API implements standard HTTP content type negotiation: passing
an Accept header containing a value of application/json;as=Table;g=meta.k8s.io;v=v1
with a GET call will request that the server return objects in the Table content
type.
For example, list all of the pods on a cluster in the Table format.
GET /api/v1/pods
Accept: application/json;as=Table;g=meta.k8s.io;v=v1
---
200 OK
Content-Type: application/json
{
"kind": "Table",
"apiVersion": "meta.k8s.io/v1",
...
"columnDefinitions": [
...
]
}
For API resource types that do not have a custom Table definition known to the control
plane, the API server returns a default Table response that consists of the resource's
name and creationTimestamp fields.
Not all API resource types support a Table response; for example, a
CustomResourceDefinitions
might not define field-to-table mappings, and an APIService that
extends the core Kubernetes API
might not serve Table responses at all. If you are implementing a client that
uses the Table information and must work against all resource types, including
extensions, you should make requests that specify multiple content types in the
Accept header. For example:
If the client indicates it only accepts ...;as=Table;g=meta.k8s.io;v=v1, servers
that don't support table responses will return a 406 error code.
If falling back to full objects in that case is desired, clients can add ,application/json
(or any other supported encoding) to their Accept header, and handle either
table or full objects in the response:
To request partial object metadata, you can request metadata only responses in the Accept
header. The Kubernetes API implements a variation on HTTP content type negotiation.
As a client, you can provide an Accept header with the desired media type,
along with parameters that indicate you want only metadata.
For example: Accept: application/json;as=PartialObjectMetadata;g=meta.k8s.io;v=v1
for JSON for a specific object and:
Accept: application/json;as=PartialObjectMetadataList;g=meta.k8s.io;v=v1 for a list.
Note:
as=PartialObjectMetadata should be used in specific resource requests, and as=PartialObjectMetadataList should be used for lists.
For example, to list all of the pods in a cluster, across all namespaces, but returning only the metadata for each pod:
For a request for a collection, the API server returns a PartialObjectMetadataList.
For a request for a single object, the API server returns a PartialObjectMetadata
representation of the
object. In both cases, the returned objects only contain the metadata field.
The spec and status fields are omitted.
This feature is useful for clients that only need to check for the existence of
an object, or that only need to read its metadata. It can significantly reduce
the size of the response from the API server.
You can request a metadata-only fetch for all available media types (JSON, YAML, CBOR and Kubernetes Protobuf).
For Protobuf, the
Accept header would be
application/vnd.kubernetes.protobuf;as=PartialObjectMetadata;g=meta.k8s.io;v=v1.
The Kubernetes API server supports partial fetching for nearly all of its built-in APIs.
However, you can use Kubernetes to access other API servers via the
aggregation layer, and those
APIs may not support partial fetches.
If a client uses the Accept header to only request a response ...;as=PartialObjectMetadata;g=meta.k8s.io;v=v1,
and accesses an API that doesn't support partial responses, Kubernetes responds
with a 406 HTTP error.
If falling back to full objects in that case is desired, clients can add ,application/json
(or any other supported encoding) to their Accept header, and handle either
PartialObjectMetadata or full objects in the response. It's a good idea to specify
that a partial response is preferred, using the q (quality) parameter. For example:
When a client first sends a delete to request the removal of a resource,
the .metadata.deletionTimestamp is set to the current time.
Once the .metadata.deletionTimestamp is set, external controllers that act on finalizers
may start performing their cleanup work at any time, in any order.
Order is not enforced between finalizers because it would introduce significant
risk of stuck .metadata.finalizers.
The .metadata.finalizers field is shared: any actor with permission can reorder it.
If the finalizer list were processed in order, then this might lead to a situation
in which the component responsible for the first finalizer in the list is
waiting for some signal (field value, external system, or other) produced by a
component responsible for a finalizer later in the list, resulting in a deadlock.
Without enforced ordering, finalizers are free to order amongst themselves and are
not vulnerable to ordering changes in the list.
Once the last finalizer is removed, the resource is actually removed from etcd.
Force deletion
FEATURE STATE:Kubernetes v1.32 [alpha](disabled by default)
Caution:
This may break the workload associated with the resource being force deleted, if it
relies on the normal deletion flow, so cluster breaking consequences may apply.
By enabling the delete option ignoreStoreReadErrorWithClusterBreakingPotential, the
user can perform an unsafe force delete operation of an undecryptable/corrupt
resource. This option is behind an ALPHA feature gate, and it is disabled by
default. In order to use this option, the cluster operator must enable the feature by
setting the command line option --feature-gates=AllowUnsafeMalformedObjectDeletion=true.
Note:
The user performing the force delete operation must have the privileges to do both
the delete and unsafe-delete-ignore-read-errors verbs on the given resource.
A resource is considered corrupt if it can not be successfully retrieved from the
storage due to:
transformation error (for example: decryption failure), or
the object failed to decode.
The API server first attempts a normal deletion, and if it fails with
a corrupt resource error then it triggers the force delete. A force delete operation
is unsafe because it ignores finalizer constraints, and skips precondition checks.
The default value for this option is false, this maintains backward compatibility.
For a delete request with ignoreStoreReadErrorWithClusterBreakingPotential
set to true, the fields dryRun, gracePeriodSeconds, orphanDependents,
preconditions, and propagationPolicy must be left unset.
Note:
If the user issues a delete request with ignoreStoreReadErrorWithClusterBreakingPotential
set to true on an otherwise readable resource, the API server aborts the request with an error.
Single resource API
The Kubernetes API verbs get, create, update, patch,
delete and proxy support single resources only.
These verbs with single resource support have no support for submitting multiple
resources together in an ordered or unordered list or transaction.
When clients (including kubectl) act on a set of resources, the client makes a series
of single-resource API requests, then aggregates the responses if needed.
By contrast, the Kubernetes API verbs list and watch allow getting multiple
resources, and deletecollection allows deleting multiple resources.
Field validation
Kubernetes always validates the type of fields. For example, if a field in the
API is defined as a number, you cannot set the field to a text value. If a field
is defined as an array of strings, you can only provide an array. Some fields
allow you to omit them, other fields are required. Omitting a required field
from an API request is an error.
If you make a request with an extra field, one that the cluster's control plane
does not recognize, then the behavior of the API server is more complicated.
By default, the API server drops fields that it does not recognize
from an input that it receives (for example, the JSON body of a PUT request).
There are two situations where the API server drops fields that you supplied in
an HTTP request.
These situations are:
The field is unrecognized because it is not in the resource's OpenAPI schema. (One
exception to this is for CRDs
that explicitly choose not to prune unknown fields via x-kubernetes-preserve-unknown-fields).
The field is duplicated in the object.
Validation for unrecognized or duplicate fields
FEATURE STATE:Kubernetes v1.27 [stable](enabled by default)
From 1.25 onward, unrecognized or duplicate fields in an object are detected via
validation on the server when you use HTTP verbs that can submit data (POST, PUT, and PATCH).
Possible levels of validation are Ignore, Warn (default), and Strict.
Ignore
The API server succeeds in handling the request as it would without the erroneous fields
being set, dropping all unknown and duplicate fields and giving no indication it
has done so.
Warn
(Default) The API server succeeds in handling the request, and reports a
warning to the client. The warning is sent using the Warning: response header,
adding one warning item for each unknown or duplicate field. For more
information about warnings and the Kubernetes API, see the blog article
Warning: Helpful Warnings Ahead.
Strict
The API server rejects the request with a 400 Bad Request error when it
detects any unknown or duplicate fields. The response message from the API
server specifies all the unknown or duplicate fields that the API server has
detected.
The field validation level is set by the fieldValidation query parameter.
Note:
If you submit a request that specifies an unrecognized field, and that is also invalid for
a different reason (for example, the request provides a string value where the API expects
an integer for a known field), then the API server responds with a 400 Bad Request error, but will
not provide any information on unknown or duplicate fields (only which fatal
error it encountered first).
You always receive an error response in this case, no matter what field validation level you requested.
Tools that submit requests to the server (such as kubectl), might set their own
defaults that are different from the Warn validation level that the API server uses
by default.
The kubectl tool uses the --validate flag to set the level of field
validation. It accepts the values ignore, warn, and strict while
also accepting the values true (equivalent to strict) and false
(equivalent to ignore). The default validation setting for kubectl is
--validate=true, which means strict server-side field validation.
When kubectl cannot connect to an API server with field validation (API servers
prior to Kubernetes 1.27), it will fall back to using client-side validation.
Client-side validation will be removed entirely in a future version of kubectl.
Note:
Prior to Kubernetes 1.25, kubectl --validate was used to toggle client-side validation on or off as
a boolean flag.
Starting from v1.33, Kubernetes (including v1.36) offers a way to define field validations using declarative tags.
This is useful for people contributing to Kubernetes itself, and it's also relevant if you're
writing your own API using Kubernetes libraries.
To learn more, see Declarative API Validation.
Dry-run
FEATURE STATE:Kubernetes v1.19 [stable](enabled by default)
When you use HTTP verbs that can modify resources (POST, PUT, PATCH, and
DELETE), you can submit your request in a dry run mode. Dry run mode helps to
evaluate a request through the typical request stages (admission chain, validation,
merge conflicts) up until persisting objects to storage. The response body for the
request is as close as possible to a non-dry-run response. Kubernetes guarantees that
dry-run requests will not be persisted in storage or have any other side effects.
Make a dry-run request
Dry-run is triggered by setting the dryRun query parameter. This parameter is a
string, working as an enum, and the only accepted values are:
[no value set]
Allow side effects. You request this with a query string such as ?dryRun
or ?dryRun&pretty=true. The response is the final object that would have been
persisted, or an error if the request could not be fulfilled.
All
Every stage runs as normal, except for the final storage stage where side effects
are prevented.
When you set ?dryRun=All, any relevant
admission controllers
are run, validating admission controllers check the request post-mutation, merge is
performed on PATCH, fields are defaulted, and schema validation occurs. The changes
are not persisted to the underlying storage, but the final object which would have
been persisted is still returned to the user, along with the normal status code.
If the non-dry-run version of a request would trigger an admission controller that has
side effects, the request will be failed rather than risk an unwanted side effect. All
built in admission control plugins support dry-run. Additionally, admission webhooks can
declare in their
configuration object
that they do not have side effects, by setting their sideEffects field to None.
Note:
If a webhook actually does have side effects, then the sideEffects field should be
set to "NoneOnDryRun". That change is appropriate provided that the webhook is also
be modified to understand the DryRun field in AdmissionReview, and to prevent side
effects on any request marked as dry runs.
Here is an example dry-run request that uses ?dryRun=All:
POST /api/v1/namespaces/test/pods?dryRun=All
Content-Type: application/json
Accept: application/json
The response would look the same as for non-dry-run request, but the values of some
generated fields may differ.
Generated values
Some values of an object are typically generated before the object is persisted. It
is important not to rely upon the values of these fields set by a dry-run request,
since these values will likely be different in dry-run mode from when the real
request is made. Some of these fields are:
name: if generateName is set, name will have a unique random name
creationTimestamp / deletionTimestamp: records the time of creation/deletion
UID: uniquely identifies
the object and is randomly generated (non-deterministic)
resourceVersion: tracks the persisted version of the object
Any field set by a mutating admission controller
For the Service resource: Ports or IP addresses that the kube-apiserver assigns to Service objects
Dry-run authorization
Authorization for dry-run and non-dry-run requests is identical. Thus, to make
a dry-run request, you must be authorized to make the non-dry-run request.
For example, to run a dry-run patch for a Deployment, you must be authorized
to perform that patch. Here is an example of a rule for Kubernetes
RBAC that allows patching
Deployments:
Kubernetes provides several ways to update existing objects.
You can read choosing an update mechanism to
learn about which approach might be best for your use case.
You can overwrite (update) an existing resource - for example, a ConfigMap -
using an HTTP PUT. For a PUT request, it is the client's responsibility to specify
the resourceVersion (taking this from the object being updated). Kubernetes uses
that resourceVersion information so that the API server can detect lost updates
and reject requests made by a client that is out of date with the cluster.
In the event that the resource has changed (the resourceVersion the client
provided is stale), the API server returns a 409 Conflict error response.
Instead of sending a PUT request, the client can send an instruction to the API
server to patch an existing resource. A patch is typically appropriate
if the change that the client wants to make isn't conditional on the existing data.
Clients that need effective detection of lost updates should consider
making their request conditional on the existing resourceVersion (either HTTP PUT or HTTP PATCH),
and then handle any retries that are needed in case there is a conflict.
The Kubernetes API supports four different PATCH operations, determined by their
corresponding HTTP Content-Type header:
application/apply-patch+yaml
Server Side Apply YAML (a Kubernetes-specific extension, based on YAML).
All JSON documents are valid YAML, so you can also submit JSON using this
media type. See Server Side Apply serialization
for more details.
To Kubernetes, this is a create operation if the object does not exist,
or a patch operation if the object already exists.
application/json-patch+json
JSON Patch, as defined in RFC6902.
A JSON patch is a sequence of operations that are executed on the resource;
for example {"op": "add", "path": "/a/b/c", "value": [ "foo", "bar" ]}.
To Kubernetes, this is a patch operation.
A patch using application/json-patch+json can include conditions to
validate consistency, allowing the operation to fail if those conditions
are not met (for example, to avoid a lost update).
application/merge-patch+json
JSON Merge Patch, as defined in RFC7386.
A JSON Merge Patch is essentially a partial representation of the resource.
The submitted JSON is combined with the current resource to create a new one,
then the new one is saved.
To Kubernetes, this is a patch operation.
application/strategic-merge-patch+json
Strategic Merge Patch (a Kubernetes-specific extension based on JSON).
Strategic Merge Patch is a custom implementation of JSON Merge Patch.
You can only use Strategic Merge Patch with built-in APIs, or with aggregated
API servers that have special support for it. You cannot use
application/strategic-merge-patch+json with any API
defined using a CustomResourceDefinition.
Note:
The Kubernetes server side apply mechanism has superseded Strategic Merge
Patch.
Kubernetes' Server Side Apply
feature allows the control plane to track managed fields for newly created objects.
Server Side Apply provides a clear pattern for managing field conflicts,
offers server-side apply and update operations, and replaces the
client-side functionality of kubectl apply.
For Server-Side Apply, Kubernetes treats the request as a create if the object
does not yet exist, and a patch otherwise. For other requests that use PATCH
at the HTTP level, the logical Kubernetes operation is always patch.
The update (HTTP PUT) operation is simple to implement and flexible,
but has drawbacks:
You need to handle conflicts where the resourceVersion of the object changes
between your client reading it and trying to write it back. Kubernetes always
detects the conflict, but you as the client author need to implement retries.
You might accidentally drop fields if you decode an object locally (for example,
using client-go, you could receive fields that your client does not know how to
handle - and then drop them as part of your update.
If there's a lot of contention on the object (even on a field, or set of fields,
that you're not trying to edit), you might have trouble sending the update.
The problem is worse for larger objects and for objects with many fields.
HTTP PATCH using JSON Patch
A patch update is helpful, because:
As you're only sending differences, you have less data to send in the PATCH
request.
You can make changes that rely on existing values, such as copying the
value of a particular field into an annotation.
Unlike with an update (HTTP PUT), making your change can happen right away
even if there are frequent changes to unrelated fields): you usually would
not need to retry.
You might still need to specify the resourceVersion (to match an existing object)
if you want to be extra careful to avoid lost updates
It's still good practice to write in some retry logic in case of errors.
You can use test conditions to careful craft specific update conditions.
For example, you can increment a counter without reading it if the existing
value matches what you expect. You can do this with no lost update risk,
even if the object has changed in other ways since you last wrote to it.
(If the test condition fails, you can fall back to reading the current value
and then write back the changed number).
However:
You need more local (client) logic to build the patch; it helps a lot if you have
a library implementation of JSON Patch, or even for making a JSON Patch specifically against Kubernetes.
As the author of client software, you need to be careful when building the patch
(the HTTP request body) not to drop fields (the order of operations matters).
HTTP PATCH using Server-Side Apply
Server-Side Apply has some clear benefits:
A single round trip: it rarely requires making a GET request first.
and you can still detect conflicts for unexpected changes
you have the option to force override a conflict, if appropriate
Client implementations are easy to make.
You get an atomic create-or-update operation without extra effort
(similar to UPSERT in some SQL dialects).
However:
Server-Side Apply does not work at all for field changes that depend on a current value of the object.
You can only apply updates to objects. Some resources in the Kubernetes HTTP API are
not objects (they do not have a .metadata field), and Server-Side Apply
is only relevant for Kubernetes objects.
Resource versions
Resource versions are strings that identify the server's internal version of an
object. Resource versions can be used by clients to determine when objects have
changed, or to express data consistency requirements when getting, listing and
watching resources. Resource versions must be passed unmodified back to the
server.
Resource version strings are orderable as monotonically increasing integers
within the same resource type for all types served by kube-apiserver. This
includes built-in API types and types backed by custom resource definitions.
Both resource versions must be from objects of the same API group and resource
type. For example, two Deployments from the apps API group can have their
resource versions compared, but a Pod and a Deployment cannot. Provided that two
objects are retrieved from the same API resource type, you can compare them even
if they are in different namespaces.
If you are using API resources served by an extension API server, the client
needs to check whether the resource version string parses as a decimal number
(there are more details on that in the next few paragraphs). If either of two
resource version strings does not parse as a decimal number, the two strings can
be checked for equality but you cannot rely on comparisons for ordering.
Starting with Kubernetes 1.35, orderability of resource versions for all
Kubernetes types is included in Certified
Kubernetes
requirements. Base API objects and custom resources must be orderable as a
monotonically increasing integer for any 1.35+ APIServer implementation in order
to pass conformance tests.
In order to compare two resource version strings:
Ensure they meet the following requirements:
Both resource versions must be from the same resource type as described above
Both must start with a digit 1-9 and contain only digits 0-9
Resource versions are compared as arbitrary bitsize decimal integers
To compare them without relying on a fixed bitsize one can compare them as
strings. The bitsize must not be assumed to be some fixed amount.
A lexicographical comparison can be used instead as shown here:
If they are not of equal length, the longer one is greater (for example, "123" > "23")
If they are of equal length, the lexicographically greater one is greater (for example, "234" > "123")
Some examples of resource version comparisons that should work:
A helper method is available for
client-go
to perform this comparison.
resourceVersion fields in metadata
Clients find resource versions in resources, including the resources from the response
stream for a watch, or when using list to enumerate resources.
v1.meta/ObjectMeta -
The metadata.resourceVersion of a resource instance identifies the resource version the instance was last modified at.
v1.meta/ListMeta -
The metadata.resourceVersion of a resource collection (the response to a list) identifies the
resource version at which the collection was constructed.
resourceVersion parameters in query strings
The get, list, and watch operations support the resourceVersion parameter.
From version v1.19, Kubernetes API servers also support the resourceVersionMatch
parameter on list requests.
The API server interprets the resourceVersion parameter differently depending
on the operation you request, and on the value of resourceVersion. If you set
resourceVersionMatch then this also affects the way matching happens.
Semantics for get and list
For get and list, the semantics of resourceVersion are:
get:
resourceVersion unset
resourceVersion="0"
resourceVersion="{value other than 0}"
Most Recent
Any
Not older than
list:
From version v1.19, Kubernetes API servers support the resourceVersionMatch parameter
on list requests. If you set both resourceVersion and resourceVersionMatch, the
resourceVersionMatch parameter determines how the API server interprets
resourceVersion.
You should always set the resourceVersionMatch parameter when setting
resourceVersion on a list request. However, be prepared to handle the case
where the API server that responds is unaware of resourceVersionMatch
and ignores it.
Unless you have strong consistency requirements, using resourceVersionMatch=NotOlderThan and
a known resourceVersion is preferable since it can achieve better performance and scalability
of your cluster than leaving resourceVersion and resourceVersionMatch unset, which requires
quorum read to be served.
Setting the resourceVersionMatch parameter without setting resourceVersion is not valid.
This table explains the behavior of list requests with various combinations of
resourceVersion and resourceVersionMatch:
resourceVersionMatch and paging parameters for list
resourceVersionMatch param
paging params
resourceVersion not set
resourceVersion="0"
resourceVersion="{value other than 0}"

resourceVersionMatch=NotOlderThan
limit=<n>, continue unset
Invalid
Any
Not older than
Note:
If your cluster's API server does not honor the resourceVersionMatch parameter,
the behavior is the same as if you did not set it.
The meaning of the get and list semantics are:
Any
Return data at any resource version. The newest available resource version is preferred,
but strong consistency is not required; data at any resource version may be served. It is possible
for the request to return data at a much older resource version that the client has previously
observed, particularly in high availability configurations, due to partitions or stale
caches. Clients that cannot tolerate this should not use this semantic.
Always served from watch cache, improving performance and reducing etcd load.
Most recent
Return data at the most recent resource version. The returned data must be
consistent (in detail: served from etcd via a quorum read).
For etcd v3.4.31+ and v3.5.13+, Kubernetes 1.36 serves “most recent” reads from the watch cache:
an internal, in-memory store within the API server that caches and mirrors the state of data
persisted into etcd. Kubernetes requests progress notification to maintain cache consistency against
the etcd persistence layer. Kubernetes v1.28 through to v1.30 also supported this
feature, although as Alpha it was not recommended for production nor enabled by default until the v1.31 release.
Not older than
Return data at least as new as the provided resourceVersion. The newest
available data is preferred, but any data not older than the provided resourceVersion may be
served. For list requests to servers that honor the resourceVersionMatch parameter, this
guarantees that the collection's .metadata.resourceVersion is not older than the requested
resourceVersion, but does not make any guarantee about the .metadata.resourceVersion of any
of the items in that collection.
Always served from watch cache, improving performance and reducing etcd load.
Exact
Return data at the exact resource version provided. If the provided resourceVersion is
unavailable, the server responds with HTTP 410 Gone. For list requests to servers that honor the
resourceVersionMatch parameter, this guarantees that the collection's .metadata.resourceVersion
is the same as the resourceVersion you requested in the query string. That guarantee does
not apply to the .metadata.resourceVersion of any items within that collection.
With the ListFromCacheSnapshot feature gate enabled by default,
API server will attempt to serve the response from snapshots if one is available with resourceVersion older than requested.
This improves performance and reduces etcd load. API server starts with no snapshots,
creates a new snapshot on every watch event and keeps them until it detects etcd is compacted or if cache is full with events older than 75 seconds.
If the provided resourceVersion is unavailable, the server will fallback to etcd.
Continuation
Return the next page of data for a paginated list request, ensuring consistency with the exact resourceVersion established by the initial request in the sequence.
Response to list requests with limit include continue token, that encodes the resourceVersion and last observed position from which to resume the list.
If the resourceVersion in the provided continue token is unavailable, the server responds with HTTP 410 Gone.
With the ListFromCacheSnapshot feature gate enabled by default,
API server will attempt to serve the response from snapshots if one is available with resourceVersion older than requested.
This improves performance and reduces etcd load. API server starts with no snapshots,
creates a new snapshot on every watch event and keeps them until it detects etcd is compacted or if cache is full with events older than 75 seconds.
If the resourceVersion in provided continue token is unavailable, the server will fallback to etcd.
Note:
When you list resources and receive a collection response, the response includes the
list metadata
of the collection as well as
object metadata
for each item in that collection. For individual objects found within a collection response,
.metadata.resourceVersion tracks when that object was last updated, and not how up-to-date
the object is when served.
When using resourceVersionMatch=NotOlderThan and limit is set, clients must
handle HTTP 410 Gone responses. For example, the client might retry with a
newer resourceVersion or fall back to resourceVersion="".
When using resourceVersionMatch=Exact and limit is unset, clients must
verify that the collection's .metadata.resourceVersion matches
the requested resourceVersion, and handle the case where it does not. For
example, the client might fall back to a request with limit set.
Semantics for watch
For watch, the semantics of resource version are:
watch:
resourceVersion for watch
resourceVersion unset
resourceVersion="0"
resourceVersion="{value other than 0}"
Get State and Start at Most Recent
Get State and Start at Any
Start at Exact
The meaning of those watch semantics are:
Get State and Start at Any
Start a watch at any resource version; the most recent resource version
available is preferred, but not required. Any starting resource version is
allowed. It is possible for the watch to start at a much older resource
version that the client has previously observed, particularly in high availability
configurations, due to partitions or stale caches. Clients that cannot tolerate
this apparent rewinding should not start a watch with this semantic. To
establish initial state, the watch begins with synthetic "Added" events for
all resource instances that exist at the starting resource version. All following
watch events are for all changes that occurred after the resource version the
watch started at.
Caution:
watches initialized this way may return arbitrarily stale
data. Please review this semantic before using it, and favor the other semantics
where possible.
Get State and Start at Most Recent
Start a watch at the most recent resource version, which must be consistent
(in detail: served from etcd via a quorum read). To establish initial state,
the watch begins with synthetic "Added" events of all resources instances
that exist at the starting resource version. All following watch events are for
all changes that occurred after the resource version the watch started at.
Start at Exact
Start a watch at an exact resource version. The watch events are for all changes
after the provided resource version. Unlike "Get State and Start at Most Recent"
and "Get State and Start at Any", the watch is not started with synthetic
"Added" events for the provided resource version. The client is assumed to already
have the initial state at the starting resource version since the client provided
the resource version.
"410 Gone" responses
Servers are not required to serve all older resource versions and may return a HTTP
410 (Gone) status code if a client requests a resourceVersion older than the
server has retained. Clients must be able to tolerate 410 (Gone) responses. See
Efficient detection of changes for details on
how to handle 410 (Gone) responses when watching resources.
If you request a resourceVersion outside the applicable limit then, depending
on whether a request is served from cache or not, the API server may reply with a
410 Gone HTTP response.
Unavailable resource versions
Servers are not required to serve unrecognized resource versions. If you request
list or get for a resource version that the API server does not recognize,
then the API server may either:
wait briefly for the resource version to become available, then timeout with a
504 (Gateway Timeout) if the provided resource versions does not become available
in a reasonable amount of time;
respond with a Retry-After response header indicating how many seconds a client
should wait before retrying the request.
If you request a resource version that an API server does not recognize, the
kube-apiserver additionally identifies its error responses with a message
Too large resource version.
If you make a watch request for an unrecognized resource version, the API server
may wait indefinitely (until the request timeout) for the resource version to become
available.
2.3 - Server-Side Apply
FEATURE STATE:Kubernetes v1.22 [stable](enabled by default)
Kubernetes supports multiple appliers collaborating to manage the fields
of a single object.
Server-Side Apply provides an optional mechanism for your cluster's control plane to track
changes to an object's fields. At the level of a specific resource, Server-Side
Apply records and tracks information about control over the fields of that object.
Server-Side Apply helps users and controllers
manage their resources through declarative configuration. Clients can create and modify
objects
declaratively by submitting their fully specified intent.
A fully specified intent is a partial object that only includes the fields and
values for which the user has an opinion. That intent either creates a new
object (using default values for unspecified fields), or is
combined, by the API server, with the existing object.
Comparison with Client-Side Apply explains
how Server-Side Apply differs from the original, client-side kubectl apply
implementation.
Field management
The Kubernetes API server tracks managed fields for all newly created objects.
When trying to apply an object, fields that have a different value and are owned by
another manager will result in a conflict. This is done
in order to signal that the operation might undo another collaborator's changes.
Writes to objects with managed fields can be forced, in which case the value of any
conflicted field will be overridden, and the ownership will be transferred.
Whenever a field's value does change, ownership moves from its current manager to the
manager making the change.
For a user to manage a field, in the Server-Side Apply sense, means that the
user relies on and expects the value of the field not to change. The user who
last made an assertion about the value of a field will be recorded as the
current field manager. This can be done by changing the field manager
details explicitly using HTTP POST (create), PUT (update), or non-apply
PATCH (patch). You can also declare and record a field manager
by including a value for that field in a Server-Side Apply operation.
A Server-Side Apply patch request requires the client to provide its identity
as a field manager. When using Server-Side Apply, trying to change a
field that is controlled by a different manager results in a rejected
request unless the client forces an override.
For details of overrides, see Conflicts.
When two or more appliers set a field to the same value, they share ownership of
that field. Any subsequent attempt to change the value of the shared field, by any of
the appliers, results in a conflict. Shared field owners may give up ownership
of a field by making a Server-Side Apply patch request that doesn't include
that field.
Field management details are stored in a managedFields field that is part of an
object's metadata.
If you remove a field from a manifest and apply that manifest, Server-Side
Apply checks if there are any other field managers that also own the field.
If the field is not owned by any other field managers, it is either deleted
from the live object or reset to its default value, if it has one.
The same rule applies to associative list or map items.
Compared to the (legacy)
kubectl.kubernetes.io/last-applied-configuration
annotation managed by kubectl, Server-Side Apply uses a more declarative
approach, that tracks a user's (or client's) field management, rather than
a user's last applied state. As a side effect of using Server-Side Apply,
information about which field manager manages each field in an object also
becomes available.
Example
A simple example of an object created using Server-Side Apply could look like this:
Note:
kubectl get omits managed fields by default.
Add --show-managed-fields to show managedFields when the output format is either json or yaml.
---apiVersion:v1kind:ConfigMapmetadata:name:test-cmnamespace:defaultlabels:test-label:testmanagedFields:- manager:kubectloperation: Apply # note capitalization:"Apply"(or "Update")apiVersion:v1time:"2010-10-10T0:00:00Z"fieldsType:FieldsV1fieldsV1:f:metadata:f:labels:f:test-label:{}f:data:f:key:{}data:key:some value
That example ConfigMap object contains a single field management record in
.metadata.managedFields. The field management record consists of basic information
about the managing entity itself, plus details about the fields being managed and
the relevant operation (Apply or Update). If the request that last changed that
field was a Server-Side Apply patch then the value of operation is Apply;
otherwise, it is Update.
There is another possible outcome. A client could submit an invalid request
body. If the fully specified intent does not produce a valid object, the
request fails.
It is however possible to change .metadata.managedFields through an
update, or through a patch operation that does not use Server-Side Apply.
Doing so is highly discouraged, but might be a reasonable option to try if,
for example, the .metadata.managedFields get into an inconsistent state
(which should not happen in normal operations).
The format of managedFields is described
in the Kubernetes API reference.
Caution:
The .metadata.managedFields field is managed by the API server.
You should avoid updating it manually.
Conflicts
A conflict is a special status error that occurs when an Apply operation tries
to change a field that another manager also claims to manage. This prevents an
applier from unintentionally overwriting the value set by another user. When
this occurs, the applier has 3 options to resolve the conflicts:
Overwrite value, become sole manager: If overwriting the value was
intentional (or if the applier is an automated process like a controller) the
applier should set the force query parameter to true (for kubectl apply,
you use the --force-conflicts command line parameter), and make the request
again. This forces the operation to succeed, changes the value of the field,
and removes the field from all other managers' entries in managedFields.
Don't overwrite value, give up management claim: If the applier doesn't
care about the value of the field any more, the applier can remove it from their
local model of the resource, and make a new request with that particular field
omitted. This leaves the value unchanged, and causes the field to be removed
from the applier's entry in managedFields.
Don't overwrite value, become shared manager: If the applier still cares
about the value of a field, but doesn't want to overwrite it, they can
change the value of that field in their local model of the resource so as to
match the value of the object on the server, and then make a new request that
takes into account that local update. Doing so leaves the value unchanged,
and causes that field's management to be shared by the applier along with all
other field managers that already claimed to manage it.
Field managers
Managers identify distinct workflows that are modifying the object (especially
useful on conflicts!), and can be specified through the
fieldManager
query parameter as part of a modifying request. When you Apply to a resource,
the fieldManager parameter is required.
For other updates, the API server infers a field manager identity from the
"User-Agent:" HTTP header (if present).
When you use the kubectl tool to perform a Server-Side Apply operation, kubectl
sets the manager identity to "kubectl" by default.
Serialization
At the protocol level, Kubernetes represents Server-Side Apply message bodies
as YAML, with the media type application/apply-patch+yaml.
Note:
Whether you are submitting JSON data or YAML data, use
application/apply-patch+yaml as the Content-Type header value.
All JSON documents are valid YAML. However, Kubernetes has a bug where it uses a YAML
parser that does not fully implement the YAML specification. Some JSON escapes may
not be recognized.
The serialization is the same as for Kubernetes objects, with the exception that
clients are not required to send a complete object.
Here's an example of a Server-Side Apply message body (fully specified intent):
{"apiVersion": "v1","kind": "ConfigMap"}
(this would make a no-change update, provided that it was sent as the body
of a patch request to a valid v1/configmaps resource, and with the
appropriate request Content-Type).
Operations in scope for field management
The Kubernetes API operations where field management is considered are:
Server-Side Apply (HTTP PATCH, with content type application/apply-patch+yaml)
Replacing an existing object (update to Kubernetes; PUT at the HTTP level)
Both operations update .metadata.managedFields, but behave a little differently.
Unless you specify a forced override, an apply operation that encounters field-level
conflicts always fails; by contrast, if you make a change using update that would
affect a managed field, a conflict never provokes failure of the operation.
All Server-Side Apply patch requests are required to identify themselves by providing a
fieldManager query parameter, while the query parameter is optional for update
operations. Finally, when using the Apply operation you cannot define managedFields in
the body of the request that you submit.
An example object with multiple managers could look like this:
---apiVersion:v1kind:ConfigMapmetadata:name:test-cmnamespace:defaultlabels:test-label:testmanagedFields:- manager:kubectloperation:Applytime:'2019-03-30T15:00:00.000Z'apiVersion:v1fieldsType:FieldsV1fieldsV1:f:metadata:f:labels:f:test-label:{}- manager:kube-controller-manageroperation:UpdateapiVersion:v1time:'2019-03-30T16:00:00.000Z'fieldsType:FieldsV1fieldsV1:f:data:f:key:{}data:key:new value
In this example, a second operation was run as an update by the manager called
kube-controller-manager. The update request succeeded and changed a value in the data
field, which caused that field's management to change to the kube-controller-manager.
If this update has instead been attempted using Server-Side Apply, the request
would have failed due to conflicting ownership.
Merge strategy
The merging strategy, implemented with Server-Side Apply, provides a generally
more stable object lifecycle. Server-Side Apply tries to merge fields based on
the actor who manages them instead of overruling based on values. This way
multiple actors can update the same object without causing unexpected interference.
When a user sends a fully-specified intent object to the Server-Side Apply
endpoint, the server merges it with the live object favoring the value from the
request body if it is specified in both places. If the set of items present in
the applied config is not a superset of the items applied by the same user last
time, each missing item not managed by any other appliers is removed. For
more information about how an object's schema is used to make decisions when
merging, see
sigs.k8s.io/structured-merge-diff.
The Kubernetes API (and the Go code that implements that API for Kubernetes) allows
defining merge strategy markers. These markers describe the merge strategy supported
for fields within Kubernetes objects.
For a CustomResourceDefinition,
you can set these markers when you define the custom resource.
Golang marker
OpenAPI extension
Possible values
Description
//+listType
x-kubernetes-list-type
atomic/set/map
Applicable to lists. set applies to lists that include only scalar elements. These elements must be unique. map applies to lists of nested types only. The key values (see listMapKey) must be unique in the list. atomic can apply to any list. If configured as atomic, the entire list is replaced during merge. At any point in time, a single manager owns the list. If set or map, different managers can manage entries separately.
//+listMapKey
x-kubernetes-list-map-keys
List of field names, e.g. ["port", "protocol"]
Only applicable when +listType=map. A list of field names whose values uniquely identify entries in the list. While there can be multiple keys, listMapKey is singular because keys need to be specified individually in the Go type. The key fields must be scalars.
//+mapType
x-kubernetes-map-type
atomic/granular
Applicable to maps. atomic means that the map can only be entirely replaced by a single manager. granular means that the map supports separate managers updating individual fields.
//+structType
x-kubernetes-map-type
atomic/granular
Applicable to structs; otherwise same usage and OpenAPI annotation as //+mapType.
If listType is missing, the API server interprets a
patchStrategy=merge marker as a listType=map and the
corresponding patchMergeKey marker as a listMapKey.
The atomic list type is recursive.
(In the Go code for Kubernetes, these markers are specified as
comments and code authors need not repeat them as field tags).
Custom resources and Server-Side Apply
By default, Server-Side Apply treats custom resources as unstructured data. All
keys are treated the same as struct fields, and all lists are considered atomic.
If the CustomResourceDefinition defines a
schema
that contains annotations as defined in the previous Merge Strategy
section, these annotations will be used when merging objects of this
type.
Compatibility across topology changes
On rare occurrences, the author for a CustomResourceDefinition (CRD) or built-in
may want to change the specific topology of a field in their resource,
without incrementing its API version. Changing the topology of types,
by upgrading the cluster or updating the CRD, has different consequences when
updating existing objects. There are two categories of changes: when a field goes from
map/set/granular to atomic, and the other way around.
When the listType, mapType, or structType changes from
map/set/granular to atomic, the whole list, map, or struct of
existing objects will end-up being owned by actors who owned an element
of these types. This means that any further change to these objects
would cause a conflict.
When a listType, mapType, or structType changes from atomic to
map/set/granular, the API server is unable to infer the new
ownership of these fields. Because of that, no conflict will be produced
when objects have these fields updated. For that reason, it is not
recommended to change a type from atomic to map/set/granular.
Before spec.data gets changed from atomic to granular,
manager-one owns the field spec.data, and all the fields within it
(key1 and key2). When the CRD gets changed to make spec.datagranular, manager-one continues to own the top-level field
spec.data (meaning no other managers can delete the map called data
without a conflict), but it no longer owns key1 and key2, so another
manager can then modify or delete those fields without conflict.
Using Server-Side Apply in a controller
As a developer of a controller, you can use Server-Side Apply as a way to
simplify the update logic of your controller. The main differences with a
read-modify-write and/or patch are the following:
the applied object must contain all the fields that the controller cares about.
there is no way to remove fields that haven't been applied by the controller
before (controller can still send a patch or update for these use-cases).
the object doesn't have to be read beforehand; resourceVersion doesn't have
to be specified.
It is strongly recommended for controllers to always force conflicts on objects that
they own and manage, since they might not be able to resolve or act on these conflicts.
Transferring ownership
In addition to the concurrency controls provided by conflict resolution,
Server-Side Apply provides ways to perform coordinated
field ownership transfers from users to controllers.
This is best explained by example. Let's look at how to safely transfer
ownership of the replicas field from a user to a controller while enabling
automatic horizontal scaling for a Deployment, using the HorizontalPodAutoscaler
resource and its accompanying controller.
Say a user has defined Deployment with replicas set to the desired value:
Now, the user would like to remove replicas from their configuration, so they
don't accidentally fight with the HorizontalPodAutoscaler (HPA) and its controller.
However, there is a race: it might take some time before the HPA feels the need
to adjust .spec.replicas; if the user removes .spec.replicas before the HPA writes
to the field and becomes its owner, then the API server would set .spec.replicas to
1 (the default replica count for Deployment).
This is not what the user wants to happen, even temporarily - it might well degrade
a running workload.
There are two solutions:
(basic) Leave replicas in the configuration; when the HPA eventually writes to that
field, the system gives the user a conflict over it. At that point, it is safe
to remove from the configuration.
(more advanced) If, however, the user doesn't want to wait, for example
because they want to keep the cluster legible to their colleagues, then they
can take the following steps to make it safe to remove replicas from their
configuration:
First, the user defines a new manifest containing only the replicas field:
# Save this file as 'nginx-deployment-replicas-only.yaml'.apiVersion:apps/v1kind:Deploymentmetadata:name:nginx-deploymentspec:replicas:3
Note:
The YAML file for SSA in this case only contains the fields you want to change.
You are not supposed to provide a fully compliant Deployment manifest if you only
want to modify the spec.replicas field using SSA.
The user applies that manifest using a private field manager name. In this example,
the user picked handover-to-hpa:
If the apply results in a conflict with the HPA controller, then do nothing. The
conflict indicates the controller has claimed the field earlier in the
process than it sometimes does.
At this point the user may remove the replicas field from their manifest:
Note that whenever the HPA controller sets the replicas field to a new value,
the temporary field manager will no longer own any fields and will be
automatically deleted. No further clean up is required.
Transferring ownership between managers
Field managers can transfer ownership of a field between each other by setting the field
to the same value in both of their applied configurations, causing them to share
ownership of the field. Once the managers share ownership of the field, one of them
can remove the field from their applied configuration to give up ownership and
complete the transfer to the other field manager.
Comparison with Client-Side Apply
Server-Side Apply is meant both as a replacement for the original client-side
implementation of the kubectl apply subcommand, and as simple and effective
mechanism for controllers
to enact their changes.
Compared to the last-applied annotation managed by kubectl, Server-Side
Apply uses a more declarative approach, which tracks an object's field management,
rather than a user's last applied state. This means that as a side effect of
using Server-Side Apply, information about which field manager manages each
field in an object also becomes available.
A consequence of the conflict detection and resolution implemented by Server-Side
Apply is that an applier always has up to date field values in their local
state. If they don't, they get a conflict the next time they apply. Any of the
three options to resolve conflicts results in the applied configuration being an
up to date subset of the object on the server's fields.
This is different from Client-Side Apply, where outdated values which have been
overwritten by other users are left in an applier's local config. These values
only become accurate when the user updates that specific field, if ever, and an
applier has no way of knowing whether their next apply will overwrite other
users' changes.
Another difference is that an applier using Client-Side Apply is unable to
change the API version they are using, but Server-Side Apply supports this use
case.
Migration between client-side and server-side apply
Upgrading from client-side apply to server-side apply
Client-side apply users who manage a resource with kubectl apply can start
using server-side apply with the following flag.
kubectl apply --server-side [--dry-run=server]
By default, field management of the object transfers from client-side apply to
kubectl server-side apply, without encountering conflicts.
Caution:
Keep the last-applied-configuration annotation up to date.
The annotation infers client-side applies managed fields.
Any fields not managed by client-side apply raise conflicts.
For example, if you used kubectl scale to update the replicas field after
client-side apply, then this field is not owned by client-side apply and
creates conflicts on kubectl apply --server-side.
This behavior applies to server-side apply with the kubectl field manager.
As an exception, you can opt-out of this behavior by specifying a different,
non-default field manager, as seen in the following example. The default field
manager for kubectl server-side apply is kubectl.
Downgrading from server-side apply to client-side apply
If you manage a resource with kubectl apply --server-side,
you can downgrade to client-side apply directly with kubectl apply.
Downgrading works because kubectl Server-Side Apply keeps the
last-applied-configuration annotation up-to-date if you use
kubectl apply.
This behavior applies to Server-Side Apply with the kubectl field manager.
As an exception, you can opt-out of this behavior by specifying a different,
non-default field manager, as seen in the following example. The default field
manager for kubectl server-side apply is kubectl.
The PATCH verb (for an object that supports Server-Side Apply) accepts the
unofficial application/apply-patch+yaml content type. Users of Server-Side
Apply can send partially specified objects as YAML as the body of a PATCH request
to the URI of a resource. When applying a configuration, you should always include all the
fields that are important to the outcome (such as a desired state) that you want to define.
All JSON messages are valid YAML. Therefore, in addition to using YAML request bodies for Server-Side Apply requests, you can also use JSON request bodies, as they are also valid YAML.
In either case, use the media type application/apply-patch+yaml for the HTTP request.
Access control and permissions
Since Server-Side Apply is a type of PATCH, a principal (such as a Role for Kubernetes
RBAC) requires the patch permission to
edit existing resources, and also needs the create verb permission in order to create
new resources with Server-Side Apply.
Clearing managedFields
It is possible to strip all managedFields from an object by overwriting them
using a patch (JSON Merge Patch, Strategic Merge Patch, JSON Patch), or
through an update (HTTP PUT); in other words, through every write operation
other than apply. This can be done by overwriting the managedFields field
with an empty entry. Two examples are:
This will overwrite the managedFields with a list containing a single empty
entry that then results in the managedFields being stripped entirely from the
object. Note that setting the managedFields to an empty list will not
reset the field. This is on purpose, so managedFields never get stripped by
clients not aware of the field.
In cases where the reset operation is combined with changes to other fields
than the managedFields, this will result in the managedFields being reset
first and the other changes being processed afterwards. As a result the
applier takes ownership of any fields updated in the same request.
Note:
Server-Side Apply does not correctly track ownership on
sub-resources that don't receive the resource object type. If you are
using Server-Side Apply with such a sub-resource, the changed fields
may not be tracked.
What's next
You can read about managedFields within the Kubernetes API reference for the
metadata
top level field.
2.4 - Client Libraries
This page contains an overview of the client libraries for using the Kubernetes
API from various programming languages.
To write applications using the Kubernetes REST API,
you do not need to implement the API calls and request/response types yourself.
You can use a client library for the programming language you are using.
Client libraries often handle common tasks such as authentication for you.
Most client libraries can discover and use the Kubernetes Service Account to
authenticate if the API client is running inside the Kubernetes cluster, or can
understand the kubeconfig file
format to read the credentials and the API Server address.
Note: This section links to third party projects that provide functionality required by Kubernetes. The Kubernetes project authors aren't responsible for these projects, which are listed alphabetically. To add a project to this list, read the content guide before submitting a change. More information.
The following Kubernetes API client libraries are provided and maintained by
their authors, not the Kubernetes team.
The Common Expression Language (CEL) is used
in the Kubernetes API to declare validation rules, policy rules, and other
constraints or conditions.
CEL expressions are evaluated directly in the
API server, making CEL a
convenient alternative to out-of-process mechanisms, such as webhooks, for many
extensibility use cases. Your CEL expressions continue to execute so long as the
control plane's API server component remains available.
Language overview
The CEL language
has a straightforward syntax that is similar to the expressions in C, C++, Java,
JavaScript and Go.
CEL was designed to be embedded into applications. Each CEL "program" is a
single expression that evaluates to a single value. CEL expressions are
typically short "one-liners" that inline well into the string fields of Kubernetes
API resources.
Inputs to a CEL program are "variables". Each Kubernetes API field that contains
CEL declares in the API documentation which variables are available to use for
that field. For example, in the x-kubernetes-validations[i].rules field of
CustomResourceDefinitions, the self and oldSelf variables are available and
refer to the previous and current state of the custom resource data to be
validated by the CEL expression. Other Kubernetes API fields may declare
different variables. See the API documentation of the API fields to learn which
variables are available for that field.
Example CEL expressions:
Examples of CEL expressions and the purpose of each
CEL functions, features and language settings support Kubernetes control plane
rollbacks. For example, CEL Optional Values was introduced at Kubernetes 1.29
and so only API servers at that version or newer will accept write requests to
CEL expressions that use CEL Optional Values. However, when a cluster is
rolled back to Kubernetes 1.28 CEL expressions using "CEL Optional Values" that
are already stored in API resources will continue to evaluate correctly.
Kubernetes CEL libraries
In additional to the CEL community libraries, Kubernetes includes CEL libraries
that are available everywhere CEL is used in Kubernetes.
Kubernetes list library
The list library includes indexOf and lastIndexOf, which work similar to the
strings functions of the same names. These functions either the first or last
positional index of the provided element in the list.
The list library also includes min, max and sum. Sum is supported on all
number types as well as the duration type. Min and max are supported on all
comparable types.
isSorted is also provided as a convenience function and is supported on all
comparable types.
Examples:
Examples of CEL expressions using list library functions
CEL Expression
Purpose
names.isSorted()
Verify that a list of names is kept in alphabetical order
items.map(x, x.weight).sum() == 1.0
Verify that the "weights" of a list of objects sum to 1.0
In addition to the matches function provided by the CEL standard library, the
regex library provides find and findAll, enabling a much wider range of
regex operations.
Examples:
Examples of CEL expressions using regex library functions
To make it easier and safer to process IP addresses, the following functions have been added:
isIP(string) checks if a string is a valid IP address.
ip(string) IP converts a string to an IP address object or results in an error if the string is not a valid IP address.
For both functions, the IP address must be an IPv4 or IPv6 address.
IPv4-mapped IPv6 addresses (e.g. ::ffff:1.2.3.4) are not allowed.
IP addresses with zones (e.g. fe80::1%eth0) are not allowed.
Leading zeros in IPv4 address octets are not allowed.
Once parsed via the ip function, the resulting IP object has the
following library of member functions:
Available member functions of an IP address object
Member Function
CEL Return Value
Description
isCanonical()
bool
Returns true if the IP address is in its canonical form.
There is exactly one canonical form for every IP address, so fields containing
IPs in canonical form can just be treated as strings when checking for equality or uniqueness.
family()
int
Returns the IP address family, 4 for IPv4 and 6 for IPv6.
isUnspecified()
bool
Returns true if the IP address is the unspecified address.
Either the IPv4 address "0.0.0.0" or the IPv6 address "::".
isLoopback()
bool
Returns true if the IP address is the loopback address.
Either an IPv4 address with a value of 127.x.x.x or an IPv6 address with a value of ::1.
isLinkLocalMulticast()
bool
Returns true if the IP address is a link-local multicast address.
Either an IPv4 address with a value of 224.0.0.x or an IPv6 address in the network ff00::/8.
isLinkLocalUnicast()
bool
Returns true if the IP address is a link-local unicast address.
Either an IPv4 address with a value of 169.254.x.x or an IPv6 address in the network fe80::/10.
isGlobalUnicast()
bool
Returns true if the IP address is a global unicast address.
Either an IPv4 address that is not zero or 255.255.255.255 or an IPv6 address that is not a link-local unicast, loopback or multicast address.
Examples:
Examples of CEL expressions using IP address library functions
CEL Expression
Purpose
isIP('127.0.0.1')
Returns true for a valid IP.
ip('2001:db8::abcd').isCanonical()
Returns true for a canonical IPv6.
ip('2001:DB8::ABCD').isCanonical()
Returns false because the canonical form is lowercase.
CIDR provides a CEL function library extension of CIDR notation parsing functions.
cidr
Converts a string in CIDR notation to a network address representation or results in an error if the string is not a valid CIDR notation.
The CIDR must be an IPv4 or IPv6 subnet address with a mask.
Leading zeros in IPv4 address octets are not allowed.
IPv4-mapped IPv6 addresses (e.g. ::ffff:1.2.3.4/24) are not allowed.
cidr(<string>) <CIDR>
Examples:
cidr('192.168.0.0/16') // returns an IPv4 address with a CIDR mask
cidr('::1/128') // returns an IPv6 address with a CIDR mask
cidr('192.168.0.0/33') // error
cidr('::1/129') // error
cidr('192.168.0.1/16') // error, because there are non-0 bits after the prefix
isCIDR
Returns true if a string is a valid CIDR notation representation of a subnet with mask.
The CIDR must be an IPv4 or IPv6 subnet address with a mask.
Leading zeros in IPv4 address octets are not allowed.
IPv4-mapped IPv6 addresses (e.g. ::ffff:1.2.3.4/24) are not allowed.
containsIP / containsCIDR / ip / masked / prefixLength
containsIP: Returns true if a the CIDR contains the given IP address.
The IP address must be an IPv4 or IPv6 address.
May take either a string or IP address as an argument.
containsCIDR: Returns true if a the CIDR contains the given CIDR.
The CIDR must be an IPv4 or IPv6 subnet address with a mask.
May take either a string or CIDR as an argument.
ip: Returns the IP address representation of the CIDR.
masked: Returns the CIDR representation of the network address with a masked prefix.
This can be used to return the canonical form of the CIDR network.
prefixLength: Returns the prefix length of the CIDR in bits.
This is the number of bits in the mask.
Examples:
Examples of CEL expressions using CIDR library functions
For CEL expressions in the API where a variable of type Authorizer is available,
the authorizer may be used to perform authorization checks for the principal
(authenticated user) of the request.
API resource checks are performed as follows:
Specify the group and resource to check: Authorizer.group(string).resource(string) ResourceCheck
Optionally call any combination of the following builder functions to further narrow the authorization check.
Note that these functions return the receiver type and can be chained:
ResourceCheck.subresource(string) ResourceCheck
ResourceCheck.namespace(string) ResourceCheck
ResourceCheck.name(string) ResourceCheck
Call ResourceCheck.check(verb string) Decision to perform the authorization check.
Call allowed() bool or reason() string to inspect the result of the authorization check.
Non-resource authorization performed are used as follows:
Specify only a path: Authorizer.path(string) PathCheck
Call PathCheck.check(httpVerb string) Decision to perform the authorization check.
Call allowed() bool or reason() string to inspect the result of the authorization check.
To perform an authorization check for a service account:
Authorizer.serviceAccount(namespace string, name string) Authorizer
Examples of CEL expressions using URL library functions
The format library provides functions for validating common Kubernetes string formats.
This can be useful in the messageExpression of validation rules to provide more specific error messages.
The library provides format() functions for each named format, and a generic format.named() function.
format.named(string) → ?Format: Returns the Format object for the given format name, if it exists. Otherwise, returns optional.none.
format.<formatName>() -> Format: Convenience functions for all the named formats are also available. For example, format.dns1123Label() returns the Format object for DNS-1123 labels.
<Format>.validate(string) -> list<string>?: Validates the given string against the format. Returns optional.none if the string is valid, otherwise an optional containing a list of validation error strings.
Available Formats:
The following format names are supported:
Available formats for the format library

Examples of CEL expressions using format library functions
A `messageExpression` that returns specific validation errors for a field. If the field is valid, `validate` returns `optional.none`, and `orValue` provides an empty list, resulting in an empty string.
quantity(string) Quantity converts a string to a Quantity or results in an error if the
string is not a valid quantity.
Once parsed via the quantity function, the resulting Quantity object has the
following library of member functions:
Available member functions of a Quantity

Kubernetes v1.34 adds support for parsing and comparing strings that follow the Semantic Versioning 2.0.0 specification.
Refer to the semver.org documentation for information on accepted patterns.
isSemver(string) checks if a string is a valid semantic version.
semver(string) converts a string to a Semver object or results in an error.
An optional boolean normalize argument can be passed to isSemver and semver. If true, normalization removes any "v" prefix, adds a 0 minor and patch numbers to versions with only major or major.minor components specified, and removes any leading 0s.
Once parsed via the semver function, the resulting Semver object has the
following library of member functions:
Available member functions of a Semver object
Member Function
CEL Return Value
Description
major()
int
Returns the major version number.
minor()
int
Returns the minor version number.
patch()
int
Returns the patch version number.
isLessThan(<Semver>)
bool

isGreaterThan(<Semver>)
bool
Returns true if and only if the receiver is greater than the operand.
compareTo(<Semver>)

Compares receiver to operand and returns 0 if they are equal,
1 if the receiver is greater, or -1 if the receiver is less than the operand.
Examples:
Examples of CEL expressions using semver library functions
Some Kubernetes API fields contain partially type checked CEL expressions. A
partially type checked expression is an expressions where some of the variables
are statically typed but others are dynamically typed. For example, in the CEL
expressions of
ValidatingAdmissionPolicies
the request variable is typed, but the object variable is dynamically typed.
As a result, an expression containing request.namex would fail type checking
because the namex field is not defined. However, object.namex would pass
type checking even when the namex field is not defined for the resource kinds
that object refers to, because object is dynamically typed.
The has() macro in CEL may be used in CEL expressions to check whether a field
of a dynamically typed variable is present before attempting to access the
field's value. For example:
Use has() to check field presence. Do not use has() to check whether a map
contains a key. For example, do not write
has(object.metadata.labels['example.com/environment']). For map key checks,
use the in operator instead. For example:
has(object.metadata.labels) && 'example.com/environment' in object.metadata.labels
This expression checks that metadata.labels is present before checking whether
the map contains the example.com/environment key.
Type system integration

Equality comparison for arrays with x-kubernetes-list-type of set or map ignores element
order. For example [1, 2] == [2, 1] if the arrays represent Kubernetes set values.
Concatenation on arrays with x-kubernetes-list-type use the semantics of the
list type:
set
X + Y performs a union where the array positions of all elements in
X are preserved and non-intersecting elements in Y are appended, retaining
their partial order.
map
X + Y performs a merge where the array positions of all keys in X
are preserved but the values are overwritten by values in Y when the key
sets of X and Y intersect. Elements in Y with non-intersecting keys are
appended, retaining their partial order.
Escaping
Only Kubernetes resource property names of the form
[a-zA-Z_.-/][a-zA-Z0-9_.-/]* are accessible from CEL. Accessible property
names are escaped according to the following rules when accessed in the
expression:
When you escape any of CEL's RESERVED keywords you need to match the exact property name
use the underscore escaping
(for example, int in the word sprint would not be escaped and nor would it need to be).
Examples on escaping:
Examples escaped CEL identifiers
property name
rule with escaped property name
namespace
self.__namespace__ > 0
x-prop
self.x__dash__prop > 0
redact_d
self.redact__underscores__d > 0
string
self.startsWith('kube')
Resource constraints
CEL is non-Turing complete and offers a variety of production safety controls to
limit execution time. CEL's resource constraint features provide feedback to
developers about expression complexity and help protect the API server from
excessive resource consumption during evaluation. CEL's resource constraint
features are used to prevent CEL evaluation from consuming excessive API server
resources.
A key element of the resource constraint features is a cost unit that CEL
defines as a way of tracking CPU utilization. Cost units are independent of
system load and hardware. Cost units are also deterministic; for any given CEL
expression and input data, evaluation of the expression by the CEL interpreter
will always result in the same cost.
Many of CEL's core operations have fixed costs. The simplest operations, such as
comparisons (e.g. <) have a cost of 1. Some have a higher fixed cost, for
example list literal declarations have a fixed base cost of 40 cost units.
Calls to functions implemented in native code approximate cost based on the time
complexity of the operation. For example: operations that use regular
expressions, such as match and find, are estimated using an approximated
cost of length(regexString)*length(inputString). The approximated cost
reflects the worst case time complexity of Go's RE2 implementation.
Runtime cost budget
All CEL expressions evaluated by Kubernetes are constrained by a runtime cost
budget. The runtime cost budget is an estimate of actual CPU utilization
computed by incrementing a cost unit counter while interpreting a CEL
expression. If the CEL interpreter executes too many instructions, the runtime
cost budget will be exceeded, execution of the expressions will be halted, and
an error will result.
Some Kubernetes resources define an additional runtime cost budget that bounds
the execution of multiple expressions. If the sum total of the cost of
expressions exceed the budget, execution of the expressions will be halted, and
an error will result. For example the validation of a custom resource has a
per-validation runtime cost budget for all
Validation Rules
evaluated to validate the custom resource.
Estimated cost limits
For some Kubernetes resources, the API server may also check if worst case
estimated running time of CEL expressions would be prohibitively expensive to
execute. If so, the API server prevent the CEL expression from being written to
API resources by rejecting create or update operations containing the CEL
expression to the API resources. This feature offers a stronger assurance that
CEL expressions written to the API resource will be evaluated at runtime without
exceeding the runtime cost budget.
2.6 - Kubernetes Deprecation Policy
This document details the deprecation policy for various facets of the system.
Kubernetes is a large system with many components and many contributors. As
with any such software, the feature set naturally evolves over time, and
sometimes a feature may need to be removed. This could include an API, a flag,
or even an entire feature. To avoid breaking existing users, Kubernetes follows
a deprecation policy for aspects of the system that are slated to be removed.
Deprecating parts of the API
Since Kubernetes is an API-driven system, the API has evolved over time to
reflect the evolving understanding of the problem space. The Kubernetes API is
actually a set of APIs, called "API groups", and each API group is
independently versioned. API versions fall
into 3 main tracks, each of which has different policies for deprecation:
Example
Track
v1
GA (generally available, stable)
v1beta1
Beta (pre-release)
v1alpha1
Alpha (experimental)
A given release of Kubernetes can support any number of API groups and any
number of versions of each.
The following rules govern the deprecation of elements of the API. This
includes:
REST resources (aka API objects)
Fields of REST resources
Annotations on REST resources, including "beta" annotations but not
including "alpha" annotations.
Enumerated or constant values
Component config structures
These rules are enforced between official releases, not between
arbitrary commits to master or release branches.
Rule #1: API elements may only be removed by incrementing the version of the
API group.
Once an API element has been added to an API group at a particular version, it
can not be removed from that version or have its behavior significantly
changed, regardless of track.
Note:
For historical reasons, there are 2 "monolithic" API groups - "core" (no
group name) and "extensions". Resources will incrementally be moved from these
legacy API groups into more domain-specific API groups.
Rule #2: API objects must be able to round-trip between API versions in a given
release without information loss, with the exception of whole REST resources
that do not exist in some versions.
For example, an object can be written as v1 and then read back as v2 and
converted to v1, and the resulting v1 resource will be identical to the
original. The representation in v2 might be different from v1, but the system
knows how to convert between them in both directions. Additionally, any new
field added in v2 must be able to round-trip to v1 and back, which means v1
might have to add an equivalent field or represent it as an annotation.
Rule #3: An API version in a given track may not be deprecated in favor of a less stable API version.
GA API versions can replace beta and alpha API versions.
Beta API versions can replace earlier beta and alpha API versions, but may not replace GA API versions.
Alpha API versions can replace earlier alpha API versions, but may not replace GA or beta API versions.
Rule #4a: API lifetime is determined by the API stability level
GA API versions may be marked as deprecated, but must not be removed within a major version of Kubernetes
Beta API versions are deprecated no more than 9 months or 3 minor releases after introduction (whichever is longer),
and are no longer served 9 months or 3 minor releases after deprecation (whichever is longer)
Alpha API versions may be removed in any release without prior deprecation notice
This ensures beta API support covers the maximum supported version skew of 2 releases,
and that APIs don't stagnate on unstable beta versions, accumulating production usage that will be
disrupted when support for the beta API ends.
Note:
There are no current plans for a major version revision of Kubernetes that removes GA APIs.
Note:
Until #52185 is
resolved, no API versions that have been persisted to storage may be removed.
Serving REST endpoints for those versions may be disabled (subject to the
deprecation timelines in this document), but the API server must remain capable
of decoding/converting previously persisted data from storage.
Rule #4b: The "preferred" API version and the "storage version" for a given
group may not advance until after a release has been made that supports both the
new version and the previous version
Users must be able to upgrade to a new release of Kubernetes and then roll back
to a previous release, without converting anything to the new API version or
suffering breakages (unless they explicitly used features only available in the
newer version). This is particularly evident in the stored representation of
objects.
All of this is best illustrated by examples. Imagine a Kubernetes release,
version X, which introduces a new API group. A new Kubernetes release is made
every approximately 4 months (3 per year). The following table describes which
API versions are supported in a series of subsequent releases.

REST resources (aka API objects)
Consider a hypothetical REST resource named Widget, which was present in API v1
in the above timeline, and which needs to be deprecated. We document and
announce the
deprecation in sync with release X+1. The Widget resource still exists in API
version v1 (deprecated) but not in v2alpha1. The Widget resource continues to
exist and function in releases up to and including X+8. Only in release X+9,
when API v1 has aged out, does the Widget resource cease to exist, and the
behavior get removed.
Starting in Kubernetes v1.19, making an API request to a deprecated REST API endpoint:
Returns a Warning header
(as defined in RFC7234, Section 5.5) in the API response.
Adds a "k8s.io/deprecated":"true" annotation to the
audit event recorded for the request.
Sets an apiserver_requested_deprecated_apis gauge metric to 1 in the kube-apiserver
process. The metric has labels for group, version, resource, subresource that can be joined
to the apiserver_request_total metric, and a removed_release label that indicates the
Kubernetes release in which the API will no longer be served. The following Prometheus query
returns information about requests made to deprecated APIs which will be removed in v1.22:
As with whole REST resources, an individual field which was present in API v1
must exist and function until API v1 is removed. Unlike whole resources, the
v2 APIs may choose a different representation for the field, as long as it can
be round-tripped. For example a v1 field named "magnitude" which was
deprecated might be named "deprecatedMagnitude" in API v2. When v1 is
eventually removed, the deprecated field can be removed from v2.
Enumerated or constant values
As with whole REST resources and fields thereof, a constant value which was
supported in API v1 must exist and function until API v1 is removed.
Component config structures
Component configs are versioned and managed similar to REST resources.
Future work
Over time, Kubernetes will introduce more fine-grained API versions, at which
point these rules will be adjusted as needed.
Deprecating a flag or CLI
The Kubernetes system is comprised of several different programs cooperating.
Sometimes, a Kubernetes release might remove flags or CLI commands
(collectively "CLI elements") in these programs. The individual programs
naturally sort into two main groups - user-facing and admin-facing programs,
which vary slightly in their deprecation policies. Unless a flag is explicitly
prefixed or documented as "alpha" or "beta", it is considered GA.
CLI elements are effectively part of the API to the system, but since they are
not versioned in the same way as the REST API, the rules for deprecation are as
follows:
Rule #5a: CLI elements of user-facing components (e.g. kubectl) must function
after their announced deprecation for no less than:
GA: 12 months or 2 releases (whichever is longer)
Beta: 3 months or 1 release (whichever is longer)
Alpha: 0 releases
Rule #5b: CLI elements of admin-facing components (e.g. kubelet) must function
after their announced deprecation for no less than:
GA: 6 months or 1 release (whichever is longer)
Beta: 3 months or 1 release (whichever is longer)
Alpha: 0 releases
Rule #5c: Command line interface (CLI) elements cannot be deprecated in favor of
less stable CLI elements
Similar to the Rule #3 for APIs, if an element of a command line interface is being replaced with an
alternative implementation, such as by renaming an existing element, or by switching to
use configuration sourced from a file
instead of a command line argument, that recommended alternative must be of
the same or higher stability level.
Rule #6: Deprecated CLI elements must emit warnings (optionally disable)
when used.
Deprecating a feature or behavior
Occasionally a Kubernetes release needs to deprecate some feature or behavior
of the system that is not controlled by the API or CLI. In this case, the
rules for deprecation are as follows:
Rule #7: Deprecated behaviors must function for no less than 1 year after their
announced deprecation.
If the feature or behavior is being replaced with an alternative implementation
that requires work to adopt the change, there should be an effort to simplify
the transition whenever possible. If an alternative implementation is under
Kubernetes organization control, the following rules apply:
Rule #8: The feature of behavior must not be deprecated in favor of an alternative
implementation that is less stable
For example, a generally available feature cannot be deprecated in favor of a Beta replacement.
The Kubernetes project does, however, encourage users to adopt and transitions to alternative
implementations even before they reach the same maturity level. This is particularly important
for exploring new use cases of a feature or getting an early feedback on the replacement.
Alternative implementations may sometimes be external tools or products,
for example a feature may move from the kubelet to container runtime
that is not under Kubernetes project control. In such cases, the rule cannot be
applied, but there must be an effort to ensure that there is a transition path
that does not compromise on components' maturity levels. In the example with
container runtimes, the effort may involve trying to ensure that popular container runtimes
have versions that offer the same level of stability while implementing that replacement behavior.
Deprecation rules for features and behaviors do not imply that all changes
to the system are governed by this policy.
These rules apply only to significant, user-visible behaviors which impact the
correctness of applications running on Kubernetes or that impact the
administration of Kubernetes clusters, and which are being removed entirely.
An exception to the above rule is feature gates. Feature gates are key=value
pairs that allow for users to enable/disable experimental features.
Feature gates are intended to cover the development life cycle of a feature - they
are not intended to be long-term APIs. As such, they are expected to be deprecated
and removed after a feature becomes GA or is dropped.
As a feature moves through the stages, the associated feature gate evolves.
The feature life cycle matched to its corresponding feature gate is:
Alpha: the feature gate is disabled by default and can be enabled by the user.
Beta: the feature gate is enabled by default and can be disabled by the user.
GA: the feature gate is deprecated (see "Deprecation") and becomes
non-operational.
GA, deprecation window complete: the feature gate is removed and calls to it are
no longer accepted.
Deprecation
Features can be removed at any point in the life cycle prior to GA. When features are
removed prior to GA, their associated feature gates are also deprecated.
When an invocation tries to disable a non-operational feature gate, the call fails in order
to avoid unsupported scenarios that might otherwise run silently.
In some cases, removing pre-GA features requires considerable time. Feature gates can remain
operational until their associated feature is fully removed, at which point the feature gate
itself can be deprecated.
When removing a feature gate for a GA feature also requires considerable time, calls to
feature gates may remain operational if the feature gate has no effect on the feature,
and if the feature gate causes no errors.
Features intended to be disabled by users should include a mechanism for disabling the
feature in the associated feature gate.
Versioning for feature gates is different from the previously discussed components,
therefore the rules for deprecation are as follows:
Rule #9: Feature gates must be deprecated when the corresponding feature they control
transitions a lifecycle stage as follows. Feature gates must function for no less than:
Beta feature to GA: 6 months or 2 releases (whichever is longer)
Beta feature to EOL: 3 months or 1 release (whichever is longer)
Alpha feature to EOL: 0 releases
Rule #10: Deprecated feature gates must respond with a warning when used. When a feature gate
is deprecated it must be documented in both in the release notes and the corresponding CLI help.
Both warnings and documentation must indicate whether a feature gate is non-operational.
Deprecating a metric
Each component of the Kubernetes control-plane exposes metrics (usually the
/metrics endpoint), which are typically ingested by cluster administrators.
Not all metrics are the same: some metrics are commonly used as SLIs or used
to determine SLOs, these tend to have greater import. Other metrics are more
experimental in nature or are used primarily in the Kubernetes development
process.
Accordingly, metrics fall under three stability classes (ALPHA, BETASTABLE);
this impacts removal of a metric during a Kubernetes release. These classes
are determined by the perceived importance of the metric. The rules for
deprecating and removing a metric are as follows:
Rule #11a: Metrics, for the corresponding stability class, must function for no less than:
STABLE: 4 releases or 12 months (whichever is longer)
BETA: 2 releases or 8 months (whichever is longer)
ALPHA: 0 releases
Rule #11b: Metrics, after their announced deprecation, must function for no less than:
STABLE: 3 releases or 9 months (whichever is longer)
BETA: 1 releases or 4 months (whichever is longer)
ALPHA: 0 releases
Deprecated metrics will have their description text prefixed with a deprecation notice
string '(Deprecated from x.y)' and a warning log will be emitted during metric
registration. Like their stable undeprecated counterparts, deprecated metrics will
be automatically registered to the metrics endpoint and therefore visible.
On a subsequent release (when the metric's deprecatedVersion is equal to
current_kubernetes_version - 3), a deprecated metric will become a hidden metric.
Unlike their deprecated counterparts, hidden metrics will no longer be
automatically registered to the metrics endpoint (hence hidden). However, they
can be explicitly enabled through a command line flag on the binary
(--show-hidden-metrics-for-version=). This provides cluster admins an
escape hatch to properly migrate off of a deprecated metric, if they were not
able to react to the earlier deprecation warnings. Hidden metrics should be
deleted after one release.
Exceptions
No policy can cover every possible situation. This policy is a living
document, and will evolve over time. In practice, there will be situations
that do not fit neatly into this policy, or for which this policy becomes a
serious impediment. Such situations should be discussed with SIGs and project
leaders to find the best solutions for those specific cases, always bearing in
mind that Kubernetes is committed to being a stable system that, as much as
possible, never breaks users. Exceptions will always be announced in all
relevant release notes.

What to do
Test with deprecated APIs disabled
You can test your clusters by starting an API server with specific API versions disabled
to simulate upcoming removals. Add the following flag to the API server startup arguments:
This conversion may use non-ideal default values. To learn more about a specific
resource, check the Kubernetes API reference.
Note:
The kubectl convert tool is not installed by default, although
in fact it once was part of kubectl itself. For more details, you can read the
deprecation and removal issue
for the built-in subcommand.
To learn how to set up kubectl convert on your computer, visit the page that is right for your
operating system:
Linux,
macOS, or
Windows.
2.8 - Kubernetes API health endpoints
The Kubernetes API server provides API endpoints to indicate the current status of the API server.
This page describes these API endpoints and explains how you can use them.
API endpoints for health
The Kubernetes API server provides 3 API endpoints (healthz, livez and readyz) to indicate the current status of the API server.
The healthz endpoint is deprecated (since Kubernetes v1.16), and you should use the more specific livez and readyz endpoints instead.
The livez endpoint can be used with the --livez-grace-periodflag to specify the startup duration.
For a graceful shutdown you can specify the --shutdown-delay-durationflag with the /readyz endpoint.
Machines that check the healthz/livez/readyz of the API server should rely on the HTTP status code.
A status code 200 indicates the API server is healthy/live/ready, depending on the called endpoint.
These endpoints align with how Kubernetes HTTP probes function:
livez: Use this to determine if the API server should be restarted. If /livez returns a failure status code (such as 500), the API server is likely in a non-recoverable state, such as a deadlock, and requires a restart.
readyz: Use this to determine if the API server is ready to accept traffic. If /readyz returns a failure status code, it indicates the server is still initializing or temporarily unable to serve requests (for example, waiting for etcd to be available), and traffic should be routed away from it.
The more verbose options shown below are intended to be used by human operators to debug their cluster or understand the state of the API server.
The following examples will show how you can interact with the health API endpoints.
For all endpoints, you can use the verbose parameter to print out the checks and their status.
This can be useful for a human operator to debug the current status of the API server, it is not intended to be consumed by a machine:
curl -k https://localhost:6443/livez?verbose
or from a remote host with authentication:
kubectl get --raw='/readyz?verbose'
The output will look like this:
[+]ping ok
[+]log ok
[+]etcd ok
[+]poststarthook/start-kube-apiserver-admission-initializer ok
[+]poststarthook/generic-apiserver-start-informers ok

healthz check passed
Individual health checks
FEATURE STATE:Kubernetes v1.36 [alpha]
Each individual health check exposes an HTTP endpoint and can be checked individually.
The schema for the individual health checks is /livez/<healthcheck-name> or /readyz/<healthcheck-name>, where livez and readyz can be used to indicate if you want to check the liveness or the readiness of the API server, respectively.
The <healthcheck-name> path can be discovered using the verbose flag from above and take the path between [+] and ok.
These individual health checks should not be consumed by machines but can be helpful for a human operator to debug a system:
This page provides an overview of authentication in Kubernetes, with a focus on
authentication to the Kubernetes API.
Users in Kubernetes
All Kubernetes clusters have two categories of users: service accounts managed
by Kubernetes, and normal users.
It is assumed that a cluster-independent service manages normal users in the following ways:
an administrator distributing private keys
a user store like Keystone or Google Accounts
a file with a list of usernames and passwords
In this regard, Kubernetes does not have objects which represent normal user accounts.
Normal users cannot be added to a cluster through an API call.
Even though a normal user cannot be added via an API call, any user that
presents a valid certificate signed by the cluster's certificate authority
(CA) is considered authenticated. In this configuration, Kubernetes determines
the username from the common name field in the 'subject' of the cert (e.g.,
"/CN=bob"). From there, the role based access control (RBAC) sub-system would
determine whether the user is authorized to perform a specific operation on a
resource.
In contrast, service accounts are users managed by the Kubernetes API. They are
bound to specific namespaces, and created automatically by the API server or
manually through API calls. Service accounts are tied to a set of credentials
stored as Secrets, which are mounted into pods allowing in-cluster processes
to talk to the Kubernetes API.
API requests are tied to either a normal user or a service account, or are treated
as anonymous requests. This means every process inside or outside the cluster, from
a human user typing kubectl on a workstation, to kubelets on nodes, to members
of the control plane, must authenticate when making requests to the API server,
or be treated as an anonymous user.
If you attempt to authenticate and it succeeds, the API server automatically
marks that you are a member of the special group system:authenticated.
Authentication strategies
Kubernetes uses client certificates, bearer tokens, or an authenticating proxy to
authenticate API requests through authentication plugins. As HTTP requests are
made to the API server, plugins attempt to associate the following attributes
with the request:
Username: a string which identifies the end user. Common values might be kube-admin or jane@example.com.
UID: a string which identifies the end user and attempts to be more consistent and unique than username.
Groups: a set of strings, each of which indicates the user's membership in a named logical collection of users.
Common values might be system:masters or devops-team.
Extra fields: a map of strings to list of strings which holds additional information authorizers may find useful.
Note:
All values are opaque to the authentication system and only hold significance
when interpreted by an authorizer.
Anonymous requests
When enabled, requests that are not rejected by other configured authentication methods are
treated as anonymous requests, and given a username of system:anonymous and a group of
system:unauthenticated.
For example, on a server with token authentication configured, and anonymous access enabled,
a request providing an invalid bearer token would receive a 401 Unauthorized error.
A request providing no bearer token would be treated as an anonymous request.
Anonymous access is enabled by default if an
authorization mode
other than AlwaysAllow is used; you can disable it by passing the --anonymous-auth=false
command line option to the API server.
The built-in ABAC and RBAC authorizers require explicit authorization of the
system:anonymous user or the system:unauthenticated group; if you have legacy policy rules
(from Kubernetes version 1.5 or earlier), those legacy rules
that grant access to the * user or * group do not automatically allow access to anonymous users.
Anonymous authenticator configuration
FEATURE STATE:Kubernetes v1.34 [stable](enabled by default)
The AuthenticationConfiguration can be used to configure the anonymous
authenticator. If you set the anonymous field in the AuthenticationConfiguration
file then you cannot set the --anonymous-auth command line option.
The main advantage of configuring anonymous authenticator using the authentication
configuration file is that in addition to enabling and disabling anonymous authentication
you can also configure which endpoints support anonymous authentication.
A sample authentication configuration file is below:
---## CAUTION: this is an example configuration.# Do not use this as-is for your own cluster!#apiVersion:apiserver.config.k8s.io/v1kind:AuthenticationConfigurationanonymous:enabled:trueconditions:- path:/livez- path:/readyz- path:/healthz
In the configuration above, only the /livez, /readyz and /healthz endpoints
are reachable by anonymous requests. Any other endpoints will not be reachable
anonymously, even if your authorization configuration would allow it.
Authentication methods
You can enable multiple authentication methods at once. You should usually use at least two methods:
When multiple authenticator modules are enabled, the first module
to successfully authenticate the request short-circuits evaluation.
The API server does not guarantee the order authenticators run in.
X.509 client certificates
Any Kubernetes client that presents a valid client certificate signed by the cluster's
client trust certificate authority (CA) is considered authenticated. In this configuration, Kubernetes determines
the username from the commonName field in the subject of the certificate
(for example, commonName=bob represents a user with username "bob").
From there, Kubernetes authorization
mechanisms determine whether the user is allowed to perform a specific operation on a resource.
Client certificate authentication is enabled by passing the --client-ca-file=<SOMEFILE>
option to the API server.
This option configures the cluster's client trust certificate authority.
The referenced file must contain one or more certificate authorities that
the API server can use, when it needs to validate client certificates.
If a client certificate is presented and verified, the common name of the subject is used as
the user name for the request. Client certificates can also indicate a user's group memberships
using the certificate's organization fields. To include multiple group memberships for a user,
include multiple organization fields in the certificate.
You can present a valid certificate, issued by a CA in a trust chain that the API server accepts
for client certificates, and use that to authenticate to Kubernetes.
The certificate must be valid; the API server checks that based on the X.509 notBefore and notAfter attributes, and the certificate must have an
extended key usage that includes client authentication (ClientAuth).
Note:
Kubernetes 1.36 does not support certificate revocation.
Any certificate that is issued remains valid until it expires.
Username mapping
Kubernetes expects a client certificate that contains a commonName (OID 2.5.4.3)
attribute, that is used as the username of the subject.
User ID mapping
FEATURE STATE:Kubernetes v1.34 [beta](enabled by default)
To use this feature, the certificate must have the attribute 1.3.6.1.4.1.57683.2 included,
and the AllowParsingUserUIDFromCertAuthfeature gate
must be enabled (it is on by default).
Kubernetes can parse an optional user UID from a certificate.
UID is different from user name; it is an opaque value with a meaning defined
by the person who requested the certificate, or alternatively by whoever has
set the certificate approval rules.
For example, the UID could be 1042 (a simple integer) in one cluster, but
another certificate might use d3f77937-ec82-4f16-8010-61821abe315a (a UUID)
as the UID.
Here is an example to explain what that means. If you have a certificate with the common name
set to "Ada Lovelace" and the certificate also had a uid attribute, (OID 0.9.2342.19200300.100.1.1)
with uid set to "aaking1815", Kubernetes considers that the client's username is "Ada Lovelace";
Kubernetes ignores the uid attribute because it is not the CNCF-specific OID
that Kubernetes looks for.
If you wanted aaking1815 to be recognized as UID by Kubernetes, it must be
set as a value to the OID 1.3.6.1.4.1.57683.2 attribute in the certificate's subject.
Group mapping
You can map a user into groups by statically including group information into
the certificate. For each group that the user is a member of, add the group
name as an organization (OID 2.5.6.4) in your certificate's subject.
To include multiple group memberships for a user, include multiple organizations in the certificate subject
(the order does not matter).
For the example user, the distinguished name for a certificate might be
CN=Ada Lovelace,O=Users,O=Staff,O=Programmers, which would place her into the groups
"Programmers", "Staff", "system:authenticated", and "Users".
Putting group information into a certificate is optional; if you don't specify any groups in the certificate,
then the user will be a member of "system:authenticated" only.
Node client certificates
Kubernetes can use the same approach for node identity; nodes are clients of the Kubernetes API server that run a
kubelet
(also, although less relevant here, the API server is usually also a client of each node).
For example: a Node "server-1a-antarctica42", with the domain name "server-1a-antarctica42.cluster.example", could use a certificate issued to "CN=system:node:server-1a-antarctica/42,O=system:nodes". The node's username is then "system:node:server-1a-antarctica/g42", and the node is a member of "system:authenticated" and "system:nodes".
The kubelet uses the node's certificate and private key to authenticate to
the cluster's API server.
Note:
Machine identities for nodes are not the same as
ServiceAccounts.
Example
You could use the openssl command line tool to generate a certificate signing request:
# This example assumes that you already have a private key alovelace.pemopenssl req -new -key alovelace.pem -out alovelace-csr.pem -subj "/CN=alovelace/O=app1/O=app2"
This would create a signing request for the username "alovelace", belonging to two groups, "app1" and "app2". You could then have that signing request be signed by your cluster's client trust certificate authority to obtain a certificate you can use for client authentication to your cluster.
Bootstrap tokens
FEATURE STATE:Kubernetes v1.18 [stable]
To allow for streamlined bootstrapping for new clusters, Kubernetes includes a
dynamically-managed Bearer token type called a Bootstrap Token. These tokens
are stored as Secrets in the kube-system namespace, where they can be
dynamically managed and created. Controller Manager contains a TokenCleaner
controller that deletes bootstrap tokens as they expire.
The tokens are of the form [a-z0-9]{6}.[a-z0-9]{16}. The first component is a
Token ID and the second component is the Token Secret. You specify the token
in an HTTP header as follows:
Authorization: Bearer 781292.db7bc3a58fc5f07e
You must enable the Bootstrap Token Authenticator with the
--enable-bootstrap-token-auth flag on the API Server. You must enable
the TokenCleaner controller via the --controllers command line argument
for kube-controller-manager.
This is done with something like --controllers=*,tokencleaner.
The kubeadm tool will do this for you if you are using it to bootstrap a cluster.
The authenticator authenticates as system:bootstrap:<Token ID>. It is
included in the system:bootstrappers group. The naming and groups are
intentionally limited to discourage users from using these tokens past
bootstrapping. The user names and group can be used (and are used by kubeadm)
to craft the appropriate authorization policies to support bootstrapping a
cluster.
Please see Bootstrap Tokens for in depth
documentation on the Bootstrap Token authenticator and controllers along with
how to manage these tokens with kubeadm.
Putting a bearer token in a request
When using bearer token authentication from an HTTP client, the API
server expects an Authorization header with a value of Bearer <token>. The bearer token must be a character sequence that can be
put in an HTTP header value using no more than the encoding and
quoting facilities of HTTP. For example: if the bearer token is
31ada4fd-adec-460c-809a-9e56ceb75269 then it would appear in an HTTP
header as shown below.
A service account is an automatically enabled authenticator that uses signed
bearer tokens to verify requests. The plugin takes two optional flags:
--service-account-key-file File containing PEM-encoded x509 RSA or ECDSA
private or public keys, used to verify ServiceAccount tokens. The specified file
can contain multiple keys, and the flag can be specified multiple times with
different files. If unspecified, --tls-private-key-file is used.
--service-account-lookup If enabled, tokens which are deleted from the API will be revoked.
Service accounts are usually created automatically by the API server and
associated with pods running in the cluster through the ServiceAccountAdmission Controller. Bearer tokens are
mounted into pods at well-known locations, and allow in-cluster processes to
talk to the API server. Accounts may be explicitly associated with pods using the
serviceAccountName field of a PodSpec.
Note:
serviceAccountName is usually omitted because this is done automatically.
apiVersion:apps/v1# this apiVersion is relevant as of Kubernetes 1.9kind:Deploymentmetadata:name:nginx-deploymentnamespace:defaultspec:replicas:3template:metadata:# ...spec:serviceAccountName:bob-the-botcontainers:- name:nginximage:nginx:1.14.2
Service account bearer tokens are perfectly valid to use outside the cluster and
can be used to create identities for long standing jobs that wish to talk to the
Kubernetes API. To manually create a service account, use the kubectl create serviceaccount (NAME) command. This creates a service account in the current
namespace.
The signed JWT can be used as a bearer token to authenticate as the given service
account. See above for how the token is included
in a request. Normally these tokens are mounted into pods for in-cluster access to
the API server, but can be used from outside the cluster as well.
Service accounts authenticate with the username system:serviceaccount:(NAMESPACE):(SERVICEACCOUNT),
and are assigned to the groups system:serviceaccounts and system:serviceaccounts:(NAMESPACE).
Warning:
Because service account tokens can also be stored in Secret API objects, any user with
write access to Secrets can request a token, and any user with read access to those
Secrets can authenticate as the service account. Be cautious when granting permissions
to service accounts and read or write capabilities for Secrets.
Integrations with other authentication protocols (for example: LDAP, SAML, Kerberos, alternate X.509 schemes)
can be accomplished using an authenticating proxy or by integrating with an
authentication webhook.
You can also use any custom method that issues client X.509 certificates to clients,
provided that the API server will trust the valid certificates.
Read X.509 client certificates to learn about how to generate a
certificate.
If you do issue certificates to clients, it is up to you (as a cloud platform administrator)
to make sure that the certificate validity period, and other design choices you make, provide a
suitable level of security.
JSON Web Token authentication
You can configure Kubernetes to authenticate users using JSON Web Token
(JWT) compliant tokens. JWT authentication mechanism is used for the ServiceAccount tokens that Kubernetes itself issues,
and you can also use it to integrate with other identity sources.
The authenticator attempts to parse a raw ID token, verify it's been signed by the configured issuer.
For externally issued tokens, the public key to verify the signature is discovered from the issuer's public endpoint using OIDC discovery.
The minimum valid JWT payload must contain the following claims:
{"iss":"https://example.com",// must match the issuer.url
"aud":["my-app"],// at least one of the entries in issuer.audiences must match the "aud" claim in presented JWTs.
"exp":1234567890,// token expiration as Unix time (the number of seconds elapsed since January 1, 1970 UTC)
"<username-claim>":"user"// this is the username claim configured in the claimMappings.username.claim or claimMappings.username.expression
}
JWT egress selector type
FEATURE STATE:Kubernetes v1.34 [beta](enabled by default)
The egressSelectorType field in the JWT issuer configuration allows you to specify which egress selector
should be used for sending all traffic related to the issuer (discovery, JWKS, distributed claims, etc).
This feature requires the StructuredAuthenticationConfigurationEgressSelector feature gate to be enabled.
OpenID Connect tokens
OpenID Connect is a flavor of OAuth2 supported by
some OAuth2 providers, notably Microsoft Entra ID, Salesforce, and Google.
The protocol's main extension of OAuth2 is an additional field returned with
the access token called an ID Token.
This token is a JSON Web Token (JWT) with well known fields, such as a user's
email, signed by the server.
To identify the user, the authenticator uses the id_token (not the access_token)
from the OAuth2 token response
as a bearer token. See above for how the token
is included in a request.

Log in to your identity provider
Your identity provider will provide you with an access_token, id_token and a refresh_token
When using kubectl, use your id_token with the --token command line argument or add it directly to your kubeconfig
kubectl sends your id_token in a header called Authorization to the API server
The API server will make sure the JWT signature is valid
Check to make sure the id_token hasn't expired
Perform claim and/or user validation if CEL expressions are configured with AuthenticationConfiguration.
Make sure the user is authorized
Once authorized the API server returns a response to kubectl
kubectl provides feedback to the user
Since all of the data needed to validate who you are is in the id_token, Kubernetes doesn't need to
"phone home" to the identity provider. In a model where every request is stateless this provides a
very scalable solution for authentication. It does offer a few challenges:
Kubernetes has no "web interface" to trigger the authentication process. There is no browser or
interface to collect credentials which is why you need to authenticate to your identity provider first.
The id_token can't be revoked, it's like a certificate so it should be short-lived (only a few minutes)
so it can be very annoying to have to get a new token every few minutes.
To authenticate to the Kubernetes dashboard, you must use the kubectl proxy command or a reverse proxy
that injects the id_token.
Configuring the API Server
Using command line arguments
To enable the plugin, configure the following command line arguments for the API server:
Parameter
Description
Example
Required
--oidc-issuer-url
URL of the provider that allows the API server to discover public signing keys. Only URLs that use the https:// scheme are accepted. This is typically the provider's discovery URL, changed to have an empty path.
If the issuer's OIDC discovery URL is https://accounts.provider.example/.well-known/openid-configuration, the value should be https://accounts.provider.example
Yes
--oidc-client-id
A client id that all tokens must be issued for.
kubernetes
Yes
--oidc-username-claim
JWT claim to use as the user name. By default sub, which is expected to be a unique identifier of the end user. Admins can choose other claims, such as email or name, depending on their provider. However, claims other than email will be prefixed with the issuer URL to prevent naming clashes with other plugins.
sub
No
--oidc-username-prefix
Prefix prepended to username claims to prevent clashes with existing names (such as system: users). For example, the value oidc: will create usernames like oidc:jane.doe. If this argument isn't provided and --oidc-username-claim is a value other than email the prefix defaults to ( Issuer URL )# where ( Issuer URL ) is the value of --oidc-issuer-url. The value - can be used to disable all prefixing.
oidc:
No
--oidc-groups-claim
JWT claim to use as the user's group. If the claim is present it must be an array of strings.
groups
No
--oidc-groups-prefix
Prefix prepended to group claims to prevent clashes with existing names (such as system: groups). For example, the value oidc: will create group names like oidc:engineering and oidc:infra.
oidc:
No
--oidc-required-claim
A key=value pair that describes a required claim in the ID Token. If set, the claim is verified to be present in the ID Token with a matching value. Repeat this argument to specify multiple claims.
claim=value
No
--oidc-ca-file
The path to the certificate for the CA that signed your identity provider's web certificate. Defaults to the host's root CAs.
/etc/kubernetes/ssl/kc-ca.pem
No
--oidc-signing-algs
The signing algorithms accepted. Default is RS256. Allowed values are: RS256, RS384, RS512, ES256, ES384, ES512, PS256, PS384, PS512. Values are defined by RFC 7518 https://tools.ietf.org/html/rfc7518#section-3.1.
RS512
No
Authentication configuration from a file
FEATURE STATE:Kubernetes v1.34 [stable](enabled by default)
The configuration file approach allows you to configure multiple JWT authenticators, each with a unique
issuer.url and issuer.discoveryURL. The configuration file even allows you to specify CEL
expressions to map claims to user attributes, and to validate claims and user information.
The API server also automatically reloads the authenticators when the configuration file is modified.
You can use apiserver_authentication_config_controller_automatic_reload_last_timestamp_seconds metric
to monitor the last time the configuration was reloaded by the API server.
You must specify the path to the authentication configuration using the --authentication-config command line argument to the API server. If you want to use command line arguments instead of the configuration file, those will
continue to work as-is. To access the new capabilities like configuring multiple authenticators,
setting multiple audiences for an issuer, switch to using the configuration file.
To use structured authentication, specify the --authentication-config command line
argument to the kube-apiserver. An example of the structured authentication configuration file is shown below.
Note:
If you specify --authentication-config along with any of the --oidc-* command line arguments, this is
a misconfiguration. In this situation, the API server reports an error and then immediately exits.
If you want to switch to using structured authentication configuration, you have to remove the --oidc-*
command line arguments, and use the configuration file instead.

which will fail user validation because the username starts with system:.
The API server will return 401 Unauthorized error.
Limitations
Distributed claims do not work via CEL expressions.
Kubernetes does not provide an OpenID Connect Identity Provider.
You can use an existing public OpenID Connect Identity Provider or run your own Identity Provider
that supports the OpenID Connect protocol.
For an identity provider to work with Kubernetes it must:
The public key to verify the signature is discovered from the issuer's public endpoint using OIDC discovery.
If you're using the authentication configuration file, the identity provider doesn't need to publicly expose the discovery endpoint.
You can host the discovery endpoint at a different location than the issuer (such as locally in the cluster) and specify the
issuer.discoveryURL in the configuration file.
Run in TLS with non-obsolete ciphers
Have a CA signed certificate (even if the CA is not a commercial CA or is self signed)
A note about requirement #3 above, requiring a CA signed certificate. If you deploy your own
identity provider you MUST have your identity provider's web server certificate signed by a
certificate with the CA flag set to TRUE, even if it is self signed. This is due to GoLang's
TLS client implementation being very strict to the standards around certificate validation. If you
don't have a CA handy, you can create a simple CA and a signed certificate and key pair using
standard certificate generation tools.
Using kubectl
Option 1 - OIDC authenticator
The first option is to use the kubectl oidc authenticator, which sets the id_token as a bearer token
for all requests and refreshes the token once it expires. After you've logged into your provider, use
kubectl to add your id_token, refresh_token, client_id, and client_secret to configure the plugin.
Providers that don't return an id_token as part of their refresh token response aren't supported
by this plugin and should use Option 2 (specifying --token).
kubectl config set-credentials USER_NAME \
--auth-provider=oidc \
--auth-provider-arg=idp-issuer-url=( issuer url )\
--auth-provider-arg=client-id=( your client id )\
--auth-provider-arg=client-secret=( your client secret )\
--auth-provider-arg=refresh-token=( your refresh token )\
--auth-provider-arg=idp-certificate-authority=( path to your ca certificate )\
--auth-provider-arg=id-token=( your id_token )
As an example, running the below command after authenticating to your identity provider:
Once your id_token expires, kubectl will attempt to refresh your id_token using your refresh_token
and client_secret storing the new values for the refresh_token and id_token in your .kube/config.
Option 2 - Use the --token command line argument
The kubectl command lets you pass in a token using the --token command line argument.
Copy and paste the id_token into this option:
kubectl --token=eyJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJodHRwczovL21sYi50cmVtb2xvLmxhbjo4MDQzL2F1dGgvaWRwL29pZGMiLCJhdWQiOiJrdWJlcm5ldGVzIiwiZXhwIjoxNDc0NTk2NjY5LCJqdGkiOiI2RDUzNXoxUEpFNjJOR3QxaWVyYm9RIiwiaWF0IjoxNDc0NTk2MzY5LCJuYmYiOjE0NzQ1OTYyNDksInN1YiI6Im13aW5kdSIsInVzZXJfcm9sZSI6WyJ1c2VycyIsIm5ldy1uYW1lc3BhY2Utdmlld2VyIl0sImVtYWlsIjoibXdpbmR1QG5vbW9yZWplZGkuY29tIn0.f2As579n9VNoaKzoF-dOQGmXkFKf1FMyNV0-va_B63jn-_n9LGSCca_6IVMP8pO-Zb4KvRqGyTP0r3HkHxYy5c81AnIh8ijarruczl-TK_yF5akjSTHFZD-0gRzlevBDiH8Q79NAr-ky0P4iIXS8lY9Vnjch5MF74Zx0c3alKJHJUnnpjIACByfF2SCaYzbWFMUNat-K1PaUk5-ujMBG7yYnr95xD-63n8CO8teGUAAEMx6zRjzfhnhbzX-ajwZLGwGUBT4WqjMs70-6a7_8gZmLZb2az1cZynkFRj2BaCkVT3A2RrjeEwZEtGXlMqKJ1_I2ulrOVsYx01_yD35-rw get nodes
Webhook token authentication
Kubernetes webhook authentication is a mechanism to make an HTTP callout for verifying bearer tokens.
In terms of how you configure the API server:
--authentication-token-webhook-config-file a configuration file describing how to access the remote webhook service.
--authentication-token-webhook-cache-ttl how long to cache authentication decisions. Defaults to two minutes.
--authentication-token-webhook-version determines whether to use authentication.k8s.io/v1beta1 or authentication.k8s.io/v1TokenReview objects to send/receive information from the webhook. Defaults to v1beta1.
The configuration file uses the kubeconfig
file format. Within the file, clusters refers to the remote service and
users refers to the API server webhook. An example would be:
# Kubernetes API versionapiVersion:v1# kind of the API objectkind:Config# clusters refers to the remote service.clusters:- name:name-of-remote-authn-servicecluster:certificate-authority:/path/to/ca.pem # CA for verifying the remote service.server:https://authn.example.com/authenticate# URL of remote service to query. 'https' recommended for production.# users refers to the API server's webhook configuration.users:- name:name-of-api-serveruser:client-certificate:/path/to/cert.pem# cert for the webhook plugin to useclient-key:/path/to/key.pem # key matching the cert# kubeconfig files require a context. Provide one for the API server.current-context:webhookcontexts:- context:cluster:name-of-remote-authn-serviceuser:name-of-api-servername:webhook
When a client attempts to authenticate with the API server using a bearer token as discussed
above, the authentication webhook POSTs a JSON-serialized
TokenReview object containing the token to the remote service.
Note that webhook API objects are subject to the same versioning compatibility rules
as other Kubernetes API objects. Implementers should check the apiVersion field of the request to ensure correct deserialization,
and must respond with a TokenReview object of the same version as the request.
Note:
The Kubernetes API server defaults to sending authentication.k8s.io/v1beta1 token reviews for backwards compatibility.
To opt into receiving authentication.k8s.io/v1 token reviews, the API server must be started with --authentication-token-webhook-version=v1.
{"apiVersion": "authentication.k8s.io/v1","kind": "TokenReview","spec": {# Opaque bearer token sent to the API server"token": "014fbff9a07c...",# Optional list of the audience identifiers for the server the token was presented to.# Audience-aware token authenticators (for example, OIDC token authenticators)# should verify the token was intended for at least one of the audiences in this list,# and return the intersection of this list and the valid audiences for the token in the response status.# This ensures the token is valid to authenticate to the server it was presented to.# If no audiences are provided, the token should be validated to authenticate to the Kubernetes API server."audiences": ["https://myserver.example.com","https://myserver.internal.example.com"]}}

The remote service is expected to fill the status field of the request to indicate the success of the login.
The response body's spec field is ignored and may be omitted.
The remote service must return a response using the same TokenReview API version that it received.
A successful validation of the bearer token would return:
{"apiVersion": "authentication.k8s.io/v1","kind": "TokenReview","status": {"authenticated": true,"user": {# Required"username": "janedoe@example.com",# Optional"uid": "42",# Optional group memberships"groups": ["developers","qa"],# Optional additional information provided by the authenticator.# This should not contain confidential data, as it can be recorded in logs# or API objects, and is made available to admission webhooks."extra": {"extrafield1": ["extravalue1","extravalue2"]}},# Optional list audience-aware token authenticators can return,# containing the audiences from the `spec.audiences` list for which the provided token was valid.# If this is omitted, the token is considered to be valid to authenticate to the Kubernetes API server."audiences": ["https://myserver.example.com"]}}

An unsuccessful request would return:
{"apiVersion": "authentication.k8s.io/v1","kind": "TokenReview","status": {"authenticated": false,# Optionally include details about why authentication failed.# If no error is provided, the API will return a generic Unauthorized message.# The error field is ignored when authenticated=true."error": "Credentials are expired"}}

Authenticating reverse proxy
Warning:
If you have a certificate authority (CA) that is also used in a different context, do not trust
that certificate authority to identify authenticating proxy clients, unless you understand the
risks and the mechanisms to protect that CA's usage.
The API server can be configured to identify users from request header values, such as X-Remote-User.
It is designed for use in combination with an authenticating proxy that sets these headers.
Using an authenticating reverse proxy is different from user impersonation.
With user impersonation, one user requests the API server to treat the request as if it were being
made by a different user. With an authenticating reverse proxy, the API server trusts its direct client
to provide information about the identity of the principal making the original request.
In order to prevent header spoofing, the authenticating proxy is required to present a valid client
certificate to the API server for validation against the specified CA before the request headers are
checked.
See the command line option reference for request header
authentication mode.
Do not reuse a CA that is used in a different context unless you understand
the risks and the mechanisms to protect the CA's usage.
Static token file integration
The API server reads static bearer tokens from a file when given the --token-auth-file=<SOMEFILE>
option on the command line.
In Kubernetes 1.36, tokens last indefinitely, and the token list cannot be
changed without restarting the API server.
The token file is a CSV file with a minimum of 3 columns: token, user name, user uid,
followed by a comma-separated list of optional group names.
Note:
If you have more than one group, the column must be double quoted e.g.
token,user,uid,"group1,group2,group3"
Using a static token file is appropriate for tokens that by their nature
are long-lived, static, and perhaps may never be rotated. It is also useful
when the client is local to a particular API server within the control plane,
such as a monitoring agent.
If you use this method during cluster provisioning, and then transition to
a different authentication method that will be used longer term, you
should deactivate the token that was used for bootstrapping (this requires
a restart of each API server.
For other circumstances, and especially where very prompt token rotation is
important, the Kubernetes project recommends using a
webhook token authenticator instead of this mechanism.
User impersonation
User impersonation provides
a method that a user can act as another user through impersonation headers
You can use the following command line arguments to configure how your cluster's control plane authenticates clients.
The command line reference for the API server
describes all of the relevant command line arguments in more detail.
Anonymous authentication configuration
--anonymous-auth
Controls whether clients who have not authenticated can make request via the API server's secure port. Anonymous requests have a username of system:anonymous, and a group name of system:unauthenticated. Also see anonymous requests.
Bootstrap token configuration
--enable-bootstrap-token-auth
When this flag is set, you can use bootstrap tokens to authenticate.
Certificate authentication configuration
--client-ca-file
The path to the trust anchor(s) for validating client identity, when clients use X.509 certificate authentication.
OIDC configuration
--oidc-ca-file
The path to the trust anchor(s) for validating client identity, when clients use OIDC.
--oidc-client-id
The client ID for the OpenID Connect client.
--oidc-username-claim
The name of a JWT claim for specifying the username. claim to use as the user name. Default claim name is sub, as this should be a unique identifier of the end user. You can choose other claims, such as email or name. For claims other than sub or email, the kube-apiserver adds a prefix to the group name (to prevent naming clashes).
--oidc-username-prefix
Prefix prepended to username claims to prevent clashes with existing names (such as system: users). For example, the value oidc: will create usernames like oidc:jane.doe. If this argument isn't provided and --oidc-username-claim is a value other than email the prefix defaults to ( Issuer URL )# where ( Issuer URL ) is the value of --oidc-issuer-url. You can specify the prefix value as - to disable username prefixing.
--oidc-groups-claim
The name of a custom OpenID Connect claim for specifying user groups. The claim in the token must be an array of strings. No default.
--oidc-groups-prefix
Prefix prepended to group claims to prevent clashes with existing names (such as system: groups). For example, the value oidc: will create group names like oidc:engineering and oidc:infra. The default prefix is oidc:
--oidc-issuer-url
The URL of the OpenID issuer. The URL scheme must be https. If the issuer's OIDC discovery URL is https://accounts.provider.example/.well-known/openid-configuration, the value should be https://accounts.provider.example.
--oidc-required-claim
A claim that must be present in a token before Kubernetes authenticates a client. Format is key=value. You can specify this argument more than once.
--oidc-signing-algs
The signing algorithms accepted. Allowed values are: RS256, RS384, RS512, ES256, ES384, ES512, PS256, PS384, PS512. Values are defined by RFC 7518. Default is RS512.
ServiceAccount configuration
--api-audiences
Defines the authentication audience for service account tokens.
--service-account-extend-token-expiration
This flag turns on projected service account expiration extension during token generation, which helps safe transition from legacy tokens to bound service account token feature. See authenticating service account credentials.
--service-account-issuer
Identifier of the service account token issuer. The issuer asserts this identifier in iss claim of each issued token. The Kubernetes project recommends using a URL here, with the scheme set to https.
--service-account-jwks-uri
Overrides the URI for the JSON Web Key Set in the discovery document that is served at /.well-known/openid-configuration
--service-account-key-file
Path to a file containing PEM-encoded X.509 public or private keys (RSA or ECDSA), used to verify ServiceAccount tokens. The specified file can contain multiple keys, and you can specify the argument multiple times with different paths.
--service-account-lookup
If true, the API server validates that ServiceAccount tokens exist in etcd as part of authentication.
--service-account-max-token-expiration
The maximum validity duration of a token created by the service account token issuer, as a Kubernetes duration string.
--service-account-signing-endpoint
Path to socket where an external JWT signer is listening. You can use this to integrate with an external token signer.
--service-account-signing-key-file
Path to the file that contains the current private key of the service account token issuer. Changes made to this file while the API server is running are not re-read.
Static token configuration
--token-auth-file
Path to the configuration file for static bearer tokens. Changes made to this file while the API server is running are not re-read.
Webhook authentication configuration
--authentication-token-webhook-cache-ttl
How long (as a Kubernetes duration specification) the API server should cache the outcome of HTTP callouts to validate tokens.
--authentication-token-webhook-config-file
The path to a kubeconfig format client configuration, that specifies how the API server authenticates when making HTTP callouts. Changes made to this file while the API server is running are not re-read.
--authentication-token-webhook-version
The API version of TokenReview to use when making HTTP callouts to check tokens.
Web request authentication configuration
Caution:
You should read the documentation about configuring an authenticating proxy
before you specify these command line arguments, as there is important information security advice
that you must follow.
--requestheader-client-ca-file
Required.
Path to a PEM-encoded certificate bundle containing trust anchor(s) for validating authenticating proxy identity. A valid client certificate
must be presented and validated against the certificate authorities in the specified file before the
request headers are checked for user names.
--requestheader-allowed-names
Optional. Comma-separated list of Common Name values (CNs). If set, a valid client
certificate with a CN in the specified list must be presented before the request headers are checked
for user names. If empty, any CN is allowed.
--requestheader-username-headers
Required; case-insensitive. Header names to check, in order, for the user identity. The first header containing a value is used as the username.
--requestheader-group-headers
Optional; case-insensitive.
Header names to check, in order, for the user's groups. X-Remote-Group is suggested.
All values in all specified headers are used as group names.
--requestheader-extra-headers-prefix
Optional; case-insensitive.
Header prefixes to look for to determine extra information about the user. X-Remote-Extra- is suggested.
Extra data is typically used by the configured authorization plugin(s).
Any headers beginning with any of the specified prefixes have the prefix removed.
The remainder of the header name is lowercased and percent-decoded
and becomes the extra key, and the header value is the extra value.
Configuration via configuration file
FEATURE STATE:Kubernetes v1.34 [stable](enabled by default)
When you specify the --authentication-config command line argument to the kube-apiserver, the API server
loads a file at the path you specify, and uses the contents of that file to configure authentication.
The contents of that file can be changed while the API server is running and, if you do that, the API server re-reads the file afterwards.
Note:
Modifications to this file should be done in an atomic way (for example: writing to a peer temporary file, then renaming the temporary file to replace this file).
Here is an example of a Kubernetes (structured) authentication configuration file:
---## CAUTION: this is an example configuration.# Check and amend this before you use it in your own cluster!#apiVersion:apiserver.config.k8s.io/v1kind:AuthenticationConfigurationanonymous:enabled:false
client-go credential plugins
FEATURE STATE:Kubernetes v1.22 [stable]
k8s.io/client-go and tools using it such as kubectl and kubelet are able to execute an
external command to receive user credentials.
This feature is intended for client side integrations with authentication protocols not natively
supported by k8s.io/client-go (LDAP, Kerberos, OAuth2, SAML, etc.). The plugin implements the
protocol specific logic, then returns opaque credentials to use. Almost all credential plugin
use cases require a server side component with support for the webhook token authenticator
to interpret the credential format produced by the client plugin.
Note:
Earlier versions of kubectl included built-in support for authenticating to AKS and GKE, but this is no longer present.
Example use case
In a hypothetical use case, an organization would run an external service that exchanges LDAP credentials
for user specific, signed tokens. The service would also be capable of responding to webhook token
authenticator requests to validate the tokens. Users would be required
to install a credential plugin on their workstation.
To authenticate against the API:
The user issues a kubectl command.
Credential plugin prompts the user for LDAP credentials, exchanges credentials with external service for a token.
Credential plugin returns token to client-go, which uses it as a bearer token against the API server.
External service verifies the signature on the token and returns the user's username and groups.
Configuration
Credential plugins are configured through kubectl config files
as part of the user fields.

Relative command paths are interpreted as relative to the directory of the config file. If
KUBECONFIG is set to /home/jane/kubeconfig and the exec command is ./bin/example-client-go-exec-plugin,
the binary /home/jane/bin/example-client-go-exec-plugin is executed.

Input and output formats
The executed command prints an ExecCredential object to stdout. k8s.io/client-go
authenticates against the Kubernetes API using the returned credentials in the status.
The executed command is passed an ExecCredential object as input via the KUBERNETES_EXEC_INFO
environment variable. This input contains helpful information like the expected API version
of the returned ExecCredential object and whether or not the plugin can use stdin to interact
with the user.
When run from an interactive session (i.e., a terminal), stdin can be exposed directly
to the plugin. Plugins should use the spec.interactive field of the input
ExecCredential object from the KUBERNETES_EXEC_INFO environment variable in order to
determine if stdin has been provided. A plugin's stdin requirements (i.e., whether
stdin is optional, strictly required, or never used in order for the plugin
to run successfully) is declared via the user.exec.interactiveMode field in the
kubeconfig
(see table below for valid values). The user.exec.interactiveMode field is optional
in client.authentication.k8s.io/v1beta1 and required in client.authentication.k8s.io/v1.
interactiveMode values
interactiveMode Value
Meaning
Never
This exec plugin never needs to use standard input, and therefore the exec plugin will be run regardless of whether standard input is available for user input.
IfAvailable
This exec plugin would like to use standard input if it is available, but can still operate if standard input is not available. Therefore, the exec plugin will be run regardless of whether stdin is available for user input. If standard input is available for user input, then it will be provided to this exec plugin.
Always
This exec plugin requires standard input in order to run, and therefore the exec plugin will only be run if standard input is available for user input. If standard input is not available for user input, then the exec plugin will not be run and an error will be returned by the exec plugin runner.
To use bearer token credentials, the plugin returns a token in the status of the
ExecCredential
Alternatively, a PEM-encoded client certificate and key can be returned to use TLS client auth.
If the plugin returns a different certificate and key on a subsequent call, k8s.io/client-go
will close existing connections with the server to force a new TLS handshake.
If specified, clientKeyData and clientCertificateData must both must be present.
clientCertificateData may contain additional intermediate certificates to send to the server.
Optionally, the response can include the expiry of the credential formatted as a
RFC 3339 timestamp.
Presence or absence of an expiry has the following impact:
If an expiry is included, the bearer token and TLS credentials are cached until
the expiry time is reached, or if the server responds with a 401 HTTP status code,
or when the process exits.
If an expiry is omitted, the bearer token and TLS credentials are cached until
the server responds with a 401 HTTP status code or until the process exits.
To enable the exec plugin to obtain cluster-specific information, set provideClusterInfo on the user.exec
field in the kubeconfig.
The plugin will then be supplied this cluster-specific information in the KUBERNETES_EXEC_INFO environment variable.
Information from this environment variable can be used to perform cluster-specific
credential acquisition logic.
The following ExecCredential manifest describes a cluster information sample.

API access to authentication information for a client
FEATURE STATE:Kubernetes v1.28 [stable]
You can use the SelfSubjectReview API to find out
how your Kubernetes cluster maps your authentication information to identify you as a client.
This works whether you are authenticating as a user (typically representing
a real person) or as a ServiceAccount.
In a typical Kubernetes cluster, all authenticated users can create SelfSubjectReviews.
Access to do this is allowed by the built-in system:basic-userClusterRole.
The ability for a client to learn its own identity is extremely useful when troubleshooting a complicated authentication flow that is used in a Kubernetes cluster;
for example, if you use webhook token authentication
or an authenticating proxy.
SelfSubjectReviews do not have any configurable fields. On receiving a request, the Kubernetes
API server fills the status with the user attributes and returns it to the user.
This does not persist a named resource into your cluster: you cannot fetch the
SelfSubjectReview, and it is discarded once your POST request has completed.
Request example (the body would be a SelfSubjectReview):
POST /apis/authentication.k8s.io/v1/selfsubjectreviews
The Kubernetes API server fills userInfo after all authentication mechanisms are applied,
including impersonation.
If you, or an authentication proxy, make a SelfSubjectReview using impersonation,
you see the user details and properties for the user that was impersonated.
This example response did not show all the available fields; not all
authentication mechanisms fill in every available field.
See the SelfSubjectReview API reference
to see which fields are available.
Here is another example that also includes the uid and extra fields:
The data in these optional fields come from your authentication
integration or from the user database that it uses. The username,
UID, extra information, and all groups with names that don't start
system: are all sourced from outside of Kubernetes.
When querying the Kubernetes API via HTTP, you can request a response in either JSON or YAML
using the Accept: HTTP header; for example:
Bootstrap tokens are a simple bearer token that is meant to be used when
creating new clusters or joining new nodes to an existing cluster.
It was built to support kubeadm, but can be used in other contexts
for users that wish to start clusters without kubeadm. It is also built to
work, via RBAC policy, with the
kubelet TLS Bootstrapping system.
Bootstrap Tokens Overview
Bootstrap Tokens are defined with a specific type
(bootstrap.kubernetes.io/token) of secrets that lives in the kube-system
namespace. These Secrets are then read by the Bootstrap Authenticator in the
API Server. Expired tokens are removed with the TokenCleaner controller in the
Controller Manager. The tokens are also used to create a signature for a
specific ConfigMap used in a "discovery" process through a BootstrapSigner
controller.
Token Format
Bootstrap Tokens take the form of abcdef.0123456789abcdef.
More formally, they must match the regular expression [a-z0-9]{6}\.[a-z0-9]{16}.
The first part of the token is the "Token ID" and is considered public
information. It is used when referring to a token without leaking the secret
part used for authentication. The second part is the "Token Secret" and should
only be shared with trusted parties.
Enabling Bootstrap Token Authentication
The Bootstrap Token authenticator can be enabled using the following flag on the
API server:
--enable-bootstrap-token-auth
When enabled, bootstrapping tokens can be used as bearer token credentials to
authenticate requests against the API server.
Authorization: Bearer 07401b.f395accd246ae52d
Tokens authenticate as the username system:bootstrap:<token id> and are members
of the group system:bootstrappers.
Additional groups may be specified in the token's Secret.
Expired tokens can be deleted automatically by enabling the tokencleaner
controller on the controller manager.
--controllers=*,tokencleaner
Bootstrap Token Secret Format
Each valid token is backed by a secret in the kube-system namespace. You can
find the full design doc
here.
Here is what the secret looks like.
apiVersion:v1kind:Secretmetadata:# Name MUST be of form "bootstrap-token-<token id>"name:bootstrap-token-07401bnamespace:kube-system# Type MUST be 'bootstrap.kubernetes.io/token'type:bootstrap.kubernetes.io/tokenstringData:# Human readable description. Optional.description:"The default bootstrap token generated by 'kubeadm init'."# Token ID and secret. Required.token-id:07401btoken-secret:f395accd246ae52d# Expiration. Optional.expiration:2017-03-10T03:22:11Z# Allowed usages.usage-bootstrap-authentication:"true"usage-bootstrap-signing:"true"# Extra groups to authenticate the token as. Must start with "system:bootstrappers:"auth-extra-groups:system:bootstrappers:worker,system:bootstrappers:ingress
The type of the secret must be bootstrap.kubernetes.io/token and the name must
be bootstrap-token-<token id>. It must also exist in the kube-system namespace.
The usage-bootstrap-* members indicate what this secret is intended to be used for.
A value must be set to true to be enabled.
usage-bootstrap-authentication indicates that the token can be used to
authenticate to the API server as a bearer token.
usage-bootstrap-signing indicates that the token may be used to sign the
cluster-info ConfigMap as described below.
The expiration field controls the expiry of the token. Expired tokens are
rejected when used for authentication and ignored during ConfigMap signing.
The expiry value is encoded as an absolute UTC time using RFC3339. Enable the
tokencleaner controller to automatically delete expired tokens.
Token Management with kubeadm
You can use the kubeadm tool to manage tokens on a running cluster. See the
kubeadm token docs for details.
ConfigMap Signing
In addition to authentication, the tokens can be used to sign a ConfigMap.
This is used early in a cluster bootstrap process before the client trusts the API
server. The signed ConfigMap can be authenticated by the shared token.
Enable ConfigMap signing by enabling the bootstrapsigner controller on the
Controller Manager.
--controllers=*,bootstrapsigner
The ConfigMap that is signed is cluster-info in the kube-public namespace.
The typical flow is that a client reads this ConfigMap while unauthenticated and
ignoring TLS errors. It then validates the payload of the ConfigMap by looking
at a signature embedded in the ConfigMap.
The kubeconfig member of the ConfigMap is a config file with only the cluster
information filled out. The key thing being communicated here is the
certificate-authority-data. This may be expanded in the future.
The signature is a JWS signature using the "detached" mode. To validate the
signature, the user should encode the kubeconfig payload according to JWS
rules (base64 encoded while discarding any trailing =). That encoded payload
is then used to form a whole JWS by inserting it between the 2 dots. You can
verify the JWS using the HS256 scheme (HMAC-SHA256) with the full token (e.g.
07401b.f395accd246ae52d) as the shared secret. Users must verify that HS256
is used.
Warning:
Any party with a bootstrapping token can create a valid signature for that
token. When using ConfigMap signing it's discouraged to share the same token with
many clients, since a compromised client can potentially man-in-the middle another
client relying on the signature to bootstrap TLS trust.
Details of Kubernetes authorization mechanisms and supported authorization modes.
Kubernetes authorization takes place following
authentication.
Usually, a client making a request must be authenticated (logged in) before its
request can be allowed; however, Kubernetes also allows anonymous requests in
some circumstances.
Kubernetes authorization of API requests takes place within the API server.
The API server evaluates all of the request attributes against all policies,
potentially also consulting external services, and then allows or denies the
request.
All parts of an API request must be allowed by some authorization
mechanism in order to proceed. In other words: access is denied by default.
Note:
Access controls and policies that
depend on specific fields of specific kinds of objects are handled by
admission controllers.
Kubernetes admission control happens after authorization has completed (and,
therefore, only when the authorization decision was to allow the request).
When multiple authorization modules are configured,
each is checked in sequence.
If any authorizer approves or denies a request, that decision is immediately
returned and no other authorizer is consulted. If all modules have no opinion
on the request, then the request is denied. An overall deny verdict means that
the API server rejects the request and responds with an HTTP 403 (Forbidden)
status.
Request attributes used in authorization
Kubernetes reviews only the following API request attributes:
user - The user string provided during authentication.
group - The list of group names to which the authenticated user belongs.
extra - A map of arbitrary string keys to string values, provided by the authentication layer.
API - Indicates whether the request is for an API resource.
Request path - Path to miscellaneous non-resource endpoints like /api or /healthz.
API request verb - API verbs like get, list, create, update, patch, watch, delete, and deletecollection are used for resource requests. To determine the request verb for a resource API endpoint, see request verbs and authorization.
HTTP request verb - Lowercased HTTP methods like get, post, put, and delete are used for non-resource requests.
Resource - The ID or name of the resource that is being accessed (for resource requests only) -- For resource requests using get, update, patch, and delete verbs, you must provide the resource name.
Subresource - The subresource that is being accessed (for resource requests only). This can be a standard subresource (for example, status or scale) or a synthetic subresource used for fine-grained authorization.
Namespace - The namespace of the object that is being accessed (for namespaced resource requests only).
API group - The API Group being accessed (for resource requests only). An empty string designates the coreAPI group.
Request verbs and authorization
Non-resource requests
Requests to endpoints other than /api/v1/... or /apis/<group>/<version>/...
are considered non-resource requests, and use the lower-cased HTTP method of the request as the verb.
For example, making a GET request using HTTP to endpoints such as /api or /healthz would use get as the verb.
Resource requests
To determine the request verb for a resource API endpoint, Kubernetes maps the HTTP verb
used and considers whether or not the request acts on an individual resource or on a
collection of resources:
HTTP verb
request verb
POST
create
GET, HEAD
get (for individual resources), list (for collections, including full object content), watch (for watching an individual resource or collection of resources)
+The get, list and watch verbs can all return the full details of a resource. In
terms of access to the returned data they are equivalent. For example, list on secrets
will reveal the data attributes of any returned resources.
Kubernetes sometimes checks authorization for additional permissions using specialized verbs. For example:
Synthetic subresources such as resourceclaims/binding and resourceclaims/driver in the resource.k8s.io API group.
Node-aware verbs such as associated-node:update, associated-node:patch, arbitrary-node:update, and arbitrary-node:patch for DRA driver resourceclaims/status updates.
Authorization context
Kubernetes expects attributes that are common to REST API requests. This means
that Kubernetes authorization works with existing organization-wide or
cloud-provider-wide access control systems which may handle other APIs besides
the Kubernetes API.
Authorization modes
The Kubernetes API server may authorize a request using one of several authorization modes:
AlwaysAllow
This mode allows all requests, which brings security risks. Use this authorization mode only if you do not require authorization for your API requests (for example, for testing).
AlwaysDeny
This mode blocks all requests. Use this authorization mode only for testing.
Kubernetes ABAC mode defines an access control paradigm whereby access rights are granted to users through the use of policies which combine attributes together. The policies can use any type of attributes (user attributes, resource attributes, object, environment attributes, etc).
Kubernetes RBAC is a method of regulating access to computer or network resources based on the roles of individual users within an enterprise. In this context, access is the ability of an individual user to perform a specific task, such as view, create, or modify a file. In this mode, Kubernetes uses the rbac.authorization.k8s.io API group to drive authorization decisions, allowing you to dynamically configure permission policies through the Kubernetes API.
Node
A special-purpose authorization mode that grants permissions to kubelets based on the pods they are scheduled to run. To learn more about the Node authorization mode, see Node Authorization.
Webhook
Kubernetes webhook mode for authorization makes a synchronous HTTP callout, blocking the request until the remote HTTP service responds to the query.You can write your own software to handle the callout, or use solutions from the ecosystem.
You should not use the AlwaysAllow mode on a Kubernetes cluster where the API server
is reachable from the public internet.
The system:masters group
The system:masters group is a built-in Kubernetes group that grants unrestricted
access to the API server. Any user assigned to this group has full cluster administrator
privileges, bypassing any authorization restrictions imposed by the RBAC or Webhook mechanisms.
Avoid adding users
to this group. If you do need to grant a user cluster-admin rights, you can create a
ClusterRoleBinding
to the built-in cluster-admin ClusterRole.
You have to pick one of the two configuration approaches; setting both --authorization-config
path and configuring an authorization webhook using the --authorization-mode and
--authorization-webhook-* command line arguments is not allowed.
If you try this, the API server reports an error message during startup, then exits immediately.
FEATURE STATE:Kubernetes v1.32 [stable](enabled by default)
Kubernetes lets you configure authorization chains that can include multiple
webhooks. The authorization items in that chain can have well-defined parameters that validate
requests in a particular order, offering you fine-grained control, such as explicit Deny on failures.
The configuration file approach even allows you to specify
CEL rules to pre-filter requests before they are dispatched
to webhooks, helping you to prevent unnecessary invocations. The API server also automatically
reloads the authorizer chain when the configuration file is modified.
You specify the path to the authorization configuration using the
--authorization-config command line argument.
If you want to use command line arguments instead of a configuration file, that's also a valid and supported approach.
Some authorization capabilities (for example: multiple webhooks, webhook failure policy, and pre-filter rules)
are only available if you use an authorization configuration file.

When configuring the authorizer chain using a configuration file, make sure all the
control plane nodes have the same file contents. Take a note of the API server
configuration when upgrading / downgrading your clusters. For example, if upgrading
from Kubernetes 1.35 to Kubernetes 1.36,
you would need to make sure the config file is in a format that Kubernetes 1.36
can understand, before you upgrade the cluster. If you downgrade to 1.35,
you would need to set the configuration appropriately.
Authorization configuration and reloads
Kubernetes reloads the authorization configuration file when the API server observes a change
to the file, and also on a 60 second schedule if no change events were observed.
Note:
You must ensure that all non-webhook authorizer types remain unchanged in the file on reload.
A reload must not add or remove Node or RBAC authorizers (they can be reordered,
but cannot be added or removed).
Command line authorization mode configuration
You can use the following modes:
--authorization-mode=ABAC (Attribute-based access control mode)
--authorization-mode=RBAC (Role-based access control mode)
You can choose more than one authorization mode; for example:
--authorization-mode=Node,RBAC,Webhook
Kubernetes checks authorization modules based on the order that you specify them
on the API server's command line, so an earlier module has higher priority to allow
or deny a request.
For more information on command line arguments to the API server, read the
kube-apiserver reference.
Privilege escalation via workload creation or edits
Users who can create/edit pods in a namespace, either directly or through an object that
enables indirect workload management, may be
able to escalate their privileges in that namespace. The potential routes to privilege
escalation include Kubernetes API extensions
and their associated controllers.
Caution:
As a cluster administrator, use caution when granting access to create or edit workloads.
Some details of how these can be misused are documented in
escalation paths.
Escalation paths
There are different ways that an attacker or untrustworthy user could gain additional
privilege within a namespace, if you allow them to run arbitrary Pods in that namespace:
Mounting arbitrary Secrets in that namespace
Can be used to access confidential information meant for other workloads
Can be used to obtain a more privileged ServiceAccount's service account token
Using arbitrary ServiceAccounts in that namespace
Can perform Kubernetes API actions as another workload (impersonation)
Can perform any privileged actions that ServiceAccount has
Mounting or using ConfigMaps meant for other workloads in that namespace
Can be used to obtain information meant for other workloads, such as database host names.
Mounting volumes meant for other workloads in that namespace
Can be used to obtain information meant for other workloads, and change it.
Caution:
As a system administrator, you should be cautious when deploying CustomResourceDefinitions
that let users make changes to the above areas. These may open privilege escalations paths.
Consider the consequences of this kind of change when deciding on your authorization controls.
Checking API access
kubectl provides the auth can-i subcommand for quickly querying the API authorization layer.
The command uses the SelfSubjectAccessReview API to determine if the current user can perform
a given action, and works regardless of the authorization mode used.
kubectl auth can-i create deployments --namespace dev
SelfSubjectAccessReview is part of the authorization.k8s.io API group, which
exposes the API server authorization to external services. Other resources in
this group include:
SubjectAccessReview
Access review for any user, not only the current one. Useful for delegating authorization decisions to the API server. For example, the kubelet and extension API servers use this to determine user access to their own APIs.
LocalSubjectAccessReview
Like SubjectAccessReview but restricted to a specific namespace.
SelfSubjectRulesReview
A review which returns the set of actions a user can perform within a namespace. Useful for users to quickly summarize their own access, or for UIs to hide/show actions.
These APIs can be queried by creating normal Kubernetes resources, where the response status
field of the returned object is the result of the query. For example:
Role-based access control (RBAC) is a method of regulating access to computer or
network resources based on the roles of individual users within your organization.
RBAC authorization uses the rbac.authorization.k8s.ioAPI group to drive authorization
decisions, allowing you to dynamically configure policies through the Kubernetes API.
To enable RBAC, start the API server
with the --authorization-config flag set to a file that includes the RBAC authorizer; for example:
The RBAC API declares four kinds of Kubernetes object: Role, ClusterRole,
RoleBinding and ClusterRoleBinding. You can describe or amend the RBAC
objects
using tools such as kubectl, just like any other Kubernetes object.
Caution:
These objects, by design, impose access restrictions. If you are making changes
to a cluster as you learn, see
privilege escalation prevention and bootstrapping
to understand how those restrictions can prevent you making some changes.
Role and ClusterRole
An RBAC Role or ClusterRole contains rules that represent a set of permissions.
Permissions are purely additive (there are no "deny" rules).
A Role always sets permissions within a particular namespace;
when you create a Role, you have to specify the namespace it belongs in.
ClusterRole, by contrast, is a non-namespaced resource. The resources have different names (Role
and ClusterRole) because a Kubernetes object always has to be either namespaced or not namespaced;
it can't be both.
ClusterRoles have several uses. You can use a ClusterRole to:
define permissions on namespaced resources and be granted access within individual namespace(s)
define permissions on namespaced resources and be granted access across all namespaces
define permissions on cluster-scoped resources
If you want to define a role within a namespace, use a Role; if you want to define
a role cluster-wide, use a ClusterRole.
Role example
Here's an example Role in the "default" namespace that can be used to grant read access to
pods:
apiVersion:rbac.authorization.k8s.io/v1kind:Rolemetadata:namespace:defaultname:pod-readerrules:- apiGroups:[""]# "" indicates the core API groupresources:["pods"]verbs:["get","watch","list"]
ClusterRole example
A ClusterRole can be used to grant the same permissions as a Role.
Because ClusterRoles are cluster-scoped, you can also use them to grant access to:
namespaced resources (like Pods), across all namespaces
For example: you can use a ClusterRole to allow a particular user to run
kubectl get pods --all-namespaces
Here is an example of a ClusterRole that can be used to grant read access to
secrets in any particular namespace,
or across all namespaces (depending on how it is bound):
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:# "namespace" omitted since ClusterRoles are not namespacedname:secret-readerrules:- apiGroups:[""]## at the HTTP level, the name of the resource for accessing Secret# objects is "secrets"resources:["secrets"]verbs:["get","watch","list"]
The name of a Role or a ClusterRole object must be a valid
path segment name.
RoleBinding and ClusterRoleBinding
A role binding grants the permissions defined in a role to a user or set of users.
It holds a list of subjects (users, groups, or service accounts), and a reference to the
role being granted.
A RoleBinding grants permissions within a specific namespace whereas a ClusterRoleBinding
grants that access cluster-wide.
A RoleBinding may reference any Role in the same namespace. Alternatively, a RoleBinding
can reference a ClusterRole and bind that ClusterRole to the namespace of the RoleBinding.
If you want to bind a ClusterRole to all the namespaces in your cluster, you use a
ClusterRoleBinding.
The name of a RoleBinding or ClusterRoleBinding object must be a valid
path segment name.
RoleBinding examples
Here is an example of a RoleBinding that grants the "pod-reader" Role to the user "jane"
within the "default" namespace.
This allows "jane" to read pods in the "default" namespace.
apiVersion:rbac.authorization.k8s.io/v1# This role binding allows "jane" to read pods in the "default" namespace.# You need to already have a Role named "pod-reader" in that namespace.kind:RoleBindingmetadata:name:read-podsnamespace:defaultsubjects:# You can specify more than one "subject"- kind:Username:jane# "name" is case sensitiveapiGroup:rbac.authorization.k8s.ioroleRef:# "roleRef" specifies the binding to a Role / ClusterRolekind:Role#this must be Role or ClusterRolename:pod-reader# this must match the name of the Role or ClusterRole you wish to bind toapiGroup:rbac.authorization.k8s.io
A RoleBinding can also reference a ClusterRole to grant the permissions defined in that
ClusterRole to resources inside the RoleBinding's namespace. This kind of reference
lets you define a set of common roles across your cluster, then reuse them within
multiple namespaces.
For instance, even though the following RoleBinding refers to a ClusterRole,
"dave" (the subject, case sensitive) will only be able to read Secrets in the "development"
namespace, because the RoleBinding's namespace (in its metadata) is "development".
apiVersion:rbac.authorization.k8s.io/v1# This role binding allows "dave" to read secrets in the "development" namespace.# You need to already have a ClusterRole named "secret-reader".kind:RoleBindingmetadata:name:read-secrets## The namespace of the RoleBinding determines where the permissions are granted.# This only grants permissions within the "development" namespace.namespace:developmentsubjects:- kind:Username:dave# Name is case sensitiveapiGroup:rbac.authorization.k8s.ioroleRef:kind:ClusterRolename:secret-readerapiGroup:rbac.authorization.k8s.io
ClusterRoleBinding example
To grant permissions across a whole cluster, you can use a ClusterRoleBinding.
The following ClusterRoleBinding allows any user in the group "manager" to read
secrets in any namespace.
apiVersion:rbac.authorization.k8s.io/v1# This cluster role binding allows anyone in the "manager" group to read secrets in any namespace.kind:ClusterRoleBindingmetadata:name:read-secrets-globalsubjects:- kind:Groupname:manager# Name is case sensitiveapiGroup:rbac.authorization.k8s.ioroleRef:kind:ClusterRolename:secret-readerapiGroup:rbac.authorization.k8s.io
After you create a binding, you cannot change the Role or ClusterRole that it refers to.
If you try to change a binding's roleRef, you get a validation error. If you do want
to change the roleRef for a binding, you need to remove the binding object and create
a replacement.
There are two reasons for this restriction:
Making roleRef immutable allows granting someone update permission on an existing binding
object, so that they can manage the list of subjects, without being able to change
the role that is granted to those subjects.
A binding to a different role is a fundamentally different binding.
Requiring a binding to be deleted/recreated in order to change the roleRef
ensures the full list of subjects in the binding is intended to be granted
the new role (as opposed to enabling or accidentally modifying only the roleRef
without verifying all of the existing subjects should be given the new role's
permissions).
The kubectl auth reconcile command-line utility creates or updates a manifest file containing RBAC objects,
and handles deleting and recreating binding objects if required to change the role they refer to.
See command usage and examples for more information.
Referring to resources
In the Kubernetes API, most resources are represented and accessed using a string representation of
their object name, such as pods for a Pod. RBAC refers to resources using exactly the same
name that appears in the URL for the relevant API endpoint.
Some Kubernetes APIs involve a
subresource, such as the logs for a Pod. A request for a Pod's logs looks like:
GET /api/v1/namespaces/{namespace}/pods/{name}/log
In this case, pods is the namespaced resource for Pod resources, and log is a
subresource of pods. To represent this in an RBAC role, use a slash (/) to
delimit the resource and subresource. To allow a subject to read pods and
also access the log subresource for each of those Pods, you write:
You can also refer to resources by name for certain requests through the resourceNames list.
When specified, requests can be restricted to individual instances of a resource.
Here is an example that restricts its subject to only get or update a
ConfigMap named my-configmap:
apiVersion:rbac.authorization.k8s.io/v1kind:Rolemetadata:namespace:defaultname:configmap-updaterrules:- apiGroups:[""]## at the HTTP level, the name of the resource for accessing ConfigMap# objects is "configmaps"resources:["configmaps"]resourceNames:["my-configmap"]verbs:["update","get"]
Note:
You cannot restrict deletecollection or top-level create requests by resource name.
For create, this limitation is because the name of the new object may not be known at authorization time. However, the create limitation applies only to top-level resources, not subresources. For example, you can use the resourceNames field with pods/exec.
If you restrict list or watch by resourceName, clients must include a metadata.name field selector in their list or watch request (that matches the specified resourceName)
in order to be authorized.
For example: kubectl get configmaps --field-selector=metadata.name=my-configmap
Rather than referring to individual resources, apiGroups, and verbs,
you can use the wildcard * symbol to refer to all such objects.
For nonResourceURLs, you can use the wildcard * as a suffix glob match.
For resourceNames, an empty set means that everything is allowed.
Here is an example that allows access to perform any current and future action on
all current and future resources in the example.com API group.
This is similar to the built-in cluster-admin role.
apiVersion:rbac.authorization.k8s.io/v1kind:Rolemetadata:namespace:defaultname:example.com-superuser# DO NOT USE THIS ROLE, IT IS JUST AN EXAMPLErules:- apiGroups:["example.com"]resources:["*"]verbs:["*"]
Caution:
Using wildcards in resource and verb entries could result in overly permissive access being granted
to sensitive resources.
For instance, if a new resource type is added, or a new subresource is added,
or a new custom verb is checked, the wildcard entry automatically grants access, which may be undesirable.
The principle of least privilege
should be employed, using specific resources and verbs to ensure only the permissions required for the
workload to function correctly are applied.
Aggregated ClusterRoles
You can aggregate several ClusterRoles into one combined ClusterRole.
A controller, running as part of the cluster control plane, watches for ClusterRole
objects with an aggregationRule set. The aggregationRule defines a label
selector that the controller
uses to match other ClusterRole objects that should be combined into the rules
field of this one.
Caution:
The control plane overwrites any values that you manually specify in the rules field of an
aggregate ClusterRole. If you want to change or add rules, do so in the ClusterRole objects
that are selected by the aggregationRule.
Here is an example aggregated ClusterRole:
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:monitoringaggregationRule:clusterRoleSelectors:- matchLabels:rbac.example.com/aggregate-to-monitoring:"true"rules:[]# The control plane automatically fills in the rules
If you create a new ClusterRole that matches the label selector of an existing aggregated ClusterRole,
that change triggers adding the new rules into the aggregated ClusterRole.
Here is an example that adds rules to the "monitoring" ClusterRole, by creating another
ClusterRole labeled rbac.example.com/aggregate-to-monitoring: true.
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:monitoring-endpointsliceslabels:rbac.example.com/aggregate-to-monitoring:"true"# When you create the "monitoring-endpointslices" ClusterRole,# the rules below will be added to the "monitoring" ClusterRole.rules:- apiGroups:[""]resources:["services","pods"]verbs:["get","list","watch"]- apiGroups:["discovery.k8s.io"]resources:["endpointslices"]verbs:["get","list","watch"]
The default user-facing roles use ClusterRole aggregation. This lets you,
as a cluster administrator, include rules for custom resources, such as those served by
CustomResourceDefinitions
or aggregated API servers, to extend the default roles.
For example: the following ClusterRoles let the "admin" and "edit" default roles manage the custom resource
named CronTab, whereas the "view" role can perform only read actions on CronTab resources.
You can assume that CronTab objects are named "crontabs" in URLs as seen by the API server.
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:aggregate-cron-tabs-editlabels:# Add these permissions to the "admin" and "edit" default roles.rbac.authorization.k8s.io/aggregate-to-admin:"true"rbac.authorization.k8s.io/aggregate-to-edit:"true"rules:- apiGroups:["stable.example.com"]resources:["crontabs"]verbs:["get","list","watch","create","update","patch","delete"]---kind:ClusterRoleapiVersion:rbac.authorization.k8s.io/v1metadata:name:aggregate-cron-tabs-viewlabels:# Add these permissions to the "view" default role.rbac.authorization.k8s.io/aggregate-to-view:"true"rules:- apiGroups:["stable.example.com"]resources:["crontabs"]verbs:["get","list","watch"]

rules:- apiGroups:[""]## at the HTTP level, the name of the resource for accessing Pod# objects is "pods"resources:["pods"]verbs:["get","list","watch"]
Allow reading/writing Deployments (at the HTTP level: objects with "deployments"
in the resource part of their URL) in the "apps" API groups:
rules:- apiGroups:["apps"]## at the HTTP level, the name of the resource for accessing Deployment# objects is "deployments"resources:["deployments"]verbs:["get","list","watch","create","update","patch","delete"]
Allow reading Pods in the core API group, as well as reading or writing Job
resources in the "batch" API group:
rules:- apiGroups:[""]## at the HTTP level, the name of the resource for accessing Pod# objects is "pods"resources:["pods"]verbs:["get","list","watch"]- apiGroups:["batch"]## at the HTTP level, the name of the resource for accessing Job# objects is "jobs"resources:["jobs"]verbs:["get","list","watch","create","update","patch","delete"]
Allow reading a ConfigMap named "my-config" (must be bound with a
RoleBinding to limit to a single ConfigMap in a single namespace):
rules:- apiGroups:[""]## at the HTTP level, the name of the resource for accessing ConfigMap# objects is "configmaps"resources:["configmaps"]resourceNames:["my-config"]verbs:["get"]
Allow reading the resource "nodes" in the core group (because a

Allow GET and POST requests to the non-resource endpoint /healthz and
all subpaths (must be in a ClusterRole bound with a ClusterRoleBinding
to be effective):
rules:- nonResourceURLs:["/healthz","/healthz/*"]# '*' in a nonResourceURL is a suffix glob matchverbs:["get","post"]
Referring to subjects
A RoleBinding or ClusterRoleBinding binds a role to subjects.
Subjects can be groups, users or
ServiceAccounts.
Kubernetes represents usernames as strings.
These can be: plain names, such as "alice"; email-style names, like "bob@example.com";
or numeric user IDs represented as a string. It is up to you as a cluster administrator
to configure the authentication modules
so that authentication produces usernames in the format you want.
Caution:
The prefix system: is reserved for Kubernetes system use, so you should ensure
that you don't have users or groups with names that start with system: by
accident.
Other than this special prefix, the RBAC authorization system does not require any format
for usernames.
In Kubernetes, Authenticator modules provide group information.
Groups, like users, are represented as strings, and that string has no format requirements,
other than that the prefix system: is reserved.
ServiceAccounts have names prefixed
with system:serviceaccount:, and belong to groups that have names prefixed with system:serviceaccounts:.
Note:
system:serviceaccount: (singular) is the prefix for service account usernames.
system:serviceaccounts: (plural) is the prefix for service account groups.
RoleBinding examples
The following examples are RoleBinding excerpts that only
show the subjects section.
API servers create a set of default ClusterRole and ClusterRoleBinding objects.
Many of these are system: prefixed, which indicates that the resource is directly
managed by the cluster control plane.
All of the default ClusterRoles and ClusterRoleBindings are labeled with kubernetes.io/bootstrapping=rbac-defaults.
Caution:
Take care when modifying ClusterRoles and ClusterRoleBindings with names
that have a system: prefix.
Modifications to these resources can result in non-functional clusters.
Auto-reconciliation
At each start-up, the API server updates default cluster roles with any missing permissions,
and updates default cluster role bindings with any missing subjects.
This allows the cluster to repair accidental modifications, and helps to keep roles and role bindings
up-to-date as permissions and subjects change in new Kubernetes releases.
To opt out of this reconciliation, set the rbac.authorization.kubernetes.io/autoupdate
annotation on a default cluster role or default cluster RoleBinding to false.
Be aware that missing default permissions and subjects can result in non-functional clusters.
Auto-reconciliation is enabled by default if the RBAC authorizer is active.
API discovery roles
Default cluster role bindings authorize unauthenticated and authenticated users to read API information
that is deemed safe to be publicly accessible (including CustomResourceDefinitions).
To disable anonymous unauthenticated access, add --anonymous-auth=false flag to
the API server configuration.
To view the configuration of these roles via kubectl run:
kubectl get clusterroles system:discovery -o yaml
Note:
If you edit that ClusterRole, your changes will be overwritten on API server restart
via auto-reconciliation. To avoid that overwriting,
either do not manually edit the role, or disable auto-reconciliation.
Kubernetes RBAC API discovery roles
Default ClusterRole
Default ClusterRoleBinding
Description
system:basic-user
system:authenticated group
Allows a user read-only access to basic information about themselves. Prior to v1.14, this role was also bound to system:unauthenticated by default.
system:discovery
system:authenticated group
Allows read-only access to API discovery endpoints needed to discover and negotiate an API level. Prior to v1.14, this role was also bound to system:unauthenticated by default.
system:public-info-viewer
system:authenticated and system:unauthenticated groups
Allows read-only access to non-sensitive information about the cluster. Introduced in Kubernetes v1.14.
User-facing roles
Some of the default ClusterRoles are not system: prefixed. These are intended to be user-facing roles.
They include super-user roles (cluster-admin), roles intended to be granted cluster-wide
using ClusterRoleBindings, and roles intended to be granted within particular
namespaces using RoleBindings (admin, edit, view).
User-facing ClusterRoles use ClusterRole aggregation to allow admins to include
rules for custom resources on these ClusterRoles. To add rules to the admin, edit, or view roles, create
a ClusterRole with one or more of the following labels:
Allows super-user access to perform any action on any resource.
When used in a ClusterRoleBinding, it gives full control over every resource in the cluster and in all namespaces.
When used in a RoleBinding, it gives full control over every resource in the role binding's namespace, including the namespace itself.
admin
None
Allows admin access, intended to be granted within a namespace using a RoleBinding.
If used in a RoleBinding, allows read/write access to most resources in a namespace,
including the ability to create roles and role bindings within the namespace.
This role does not allow write access to resource quota or to the namespace itself.
This role also does not allow write access to EndpointSlices in clusters created
using Kubernetes v1.22+. More information is available in the
"Write Access for EndpointSlices" section.
edit
None
Allows read/write access to most objects in a namespace.
This role does not allow viewing or modifying roles or role bindings.
However, this role allows accessing Secrets and running Pods as any ServiceAccount in
the namespace, so it can be used to gain the API access levels of any ServiceAccount in
the namespace. This role also does not allow write access to EndpointSlices in
clusters created using Kubernetes v1.22+. More information is available in the
"Write Access for EndpointSlices" section.
view
None
Allows read-only access to see most objects in a namespace.
It does not allow viewing roles or role bindings.
This role does not allow viewing Secrets, since reading
the contents of Secrets enables access to ServiceAccount credentials
in the namespace, which would allow API access as any ServiceAccount
in the namespace (a form of privilege escalation).
Core component roles
Default ClusterRole
Default ClusterRoleBinding
Description
system:kube-scheduler
system:kube-scheduler user
Allows access to the resources required by the scheduler component.
system:volume-scheduler
system:kube-scheduler user
Allows access to the volume resources required by the kube-scheduler component.
system:kube-controller-manager
system:kube-controller-manager user
Allows access to the resources required by the controller manager component.
The permissions required by individual controllers are detailed in the controller roles.
system:node
None
Allows access to resources required by the kubelet, including read access to all secrets, and write access to all pod status objects.
You should use the Node authorizer and NodeRestriction admission plugin instead of the system:node role, and allow granting API access to kubelets based on the Pods scheduled to run on them.
The system:node role only exists for compatibility with Kubernetes clusters upgraded from versions prior to v1.8.
system:node-proxier
system:kube-proxy user
Allows access to the resources required by the kube-proxy component.
Other component roles
Default ClusterRole
Default ClusterRoleBinding
Description
system:auth-delegator
None
Allows delegated authentication and authorization checks.
This is commonly used by add-on API servers for unified authentication and authorization.
Allows read access to control-plane monitoring endpoints (i.e. kube-apiserver liveness and readiness endpoints (/healthz, /livez, /readyz), the individual health-check endpoints (/healthz/*, /livez/*, /readyz/*), /metrics), and causes the kube-apiserver to respect the traceparent header provided with requests for tracing. Note that individual health check endpoints and the metric endpoint may expose sensitive information.
Roles for built-in controllers
The Kubernetes controller manager runs
controllers that are built in to the Kubernetes
control plane.
When invoked with --use-service-account-credentials, kube-controller-manager starts each controller
using a separate service account.
Corresponding roles exist for each built-in controller, prefixed with system:controller:.
If the controller manager is not started with --use-service-account-credentials, it runs all control loops
using its own credential, which must be granted all the relevant roles.
These roles include:
The RBAC API prevents users from escalating privileges by editing roles or role bindings.
Because this is enforced at the API level, it applies even when the RBAC authorizer is not in use.
Restrictions on role creation or update
You can only create/update a role if at least one of the following things is true:
You already have all the permissions contained in the role, at the same scope as the object being modified
(cluster-wide for a ClusterRole, within the same namespace or cluster-wide for a Role).
You are granted explicit permission to perform the escalate verb on the roles or
clusterroles resource in the rbac.authorization.k8s.io API group.
For example, if user-1 does not have the ability to list Secrets cluster-wide, they cannot create a ClusterRole
containing that permission. To allow a user to create/update roles:
Grant them a role that allows them to create/update Role or ClusterRole objects, as desired.
Grant them permission to include specific permissions in the roles they create/update:
implicitly, by giving them those permissions (if they attempt to create or modify a Role or
ClusterRole with permissions they themselves have not been granted, the API request will be forbidden)
or explicitly allow specifying any permission in a Role or ClusterRole by giving them
permission to perform the escalate verb on roles or clusterroles resources in the
rbac.authorization.k8s.io API group
Restrictions on role binding creation or update
You can only create/update a role binding if you already have all the permissions contained in the referenced role
(at the same scope as the role binding) or if you have been authorized to perform the bind verb on the referenced role.
For example, if user-1 does not have the ability to list Secrets cluster-wide, they cannot create a ClusterRoleBinding
to a role that grants that permission. To allow a user to create/update role bindings:
Grant them a role that allows them to create/update RoleBinding or ClusterRoleBinding objects, as desired.
Grant them permissions needed to bind a particular role:
implicitly, by giving them the permissions contained in the role.
explicitly, by giving them permission to perform the bind verb on the particular Role (or ClusterRole).
For example, this ClusterRole and RoleBinding would allow user-1 to grant other users the admin, edit, and view roles in the namespace user-1-namespace:
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:role-grantorrules:- apiGroups:["rbac.authorization.k8s.io"]resources:["rolebindings"]verbs:["create"]- apiGroups:["rbac.authorization.k8s.io"]resources:["clusterroles"]verbs:["bind"]# omit resourceNames to allow binding any ClusterRoleresourceNames:["admin","edit","view"]---apiVersion:rbac.authorization.k8s.io/v1kind:RoleBindingmetadata:name:role-grantor-bindingnamespace:user-1-namespaceroleRef:apiGroup:rbac.authorization.k8s.iokind:ClusterRolename:role-grantorsubjects:- apiGroup:rbac.authorization.k8s.iokind:Username:user-1
When bootstrapping the first roles and role bindings, it is necessary for the initial user to grant permissions they do not yet have.
To bootstrap initial roles and role bindings:
Use a credential with the "system:masters" group, which is bound to the "cluster-admin" super-user role by the default bindings.
Command-line utilities
kubectl create role
Creates a Role object defining permissions within a single namespace. Examples:
Create a Role named "pod-reader" that allows users to perform get, watch and list on pods:
kubectl create role pod-reader --verb=get --verb=list --verb=watch --resource=pods
Create a Role named "pod-reader" with resourceNames specified:
kubectl create role pod-reader --verb=get --resource=pods --resource-name=readablepod --resource-name=anotherpod
Create a Role named "foo" with apiGroups specified:
kubectl create role foo --verb=get,list,watch --resource=replicasets.apps
Create a Role named "foo" with subresource permissions:
kubectl create role foo --verb=get,list,watch --resource=pods,pods/status
Create a Role named "my-component-lease-holder" with permissions to get/update a resource with a specific name:
kubectl create role my-component-lease-holder --verb=get,list,watch,update --resource=lease --resource-name=my-component
kubectl create clusterrole
Creates a ClusterRole. Examples:
Create a ClusterRole named "pod-reader" that allows user to perform get, watch and list on pods:
Default RBAC policies grant scoped permissions to control-plane components, nodes,
and controllers, but grant no permissions to service accounts outside the kube-system namespace
(beyond the permissions given by API discovery roles).
This allows you to grant particular roles to particular ServiceAccounts as needed.
Fine-grained role bindings provide greater security, but require more effort to administrate.
Broader grants can give unnecessary (and potentially escalating) API access to
ServiceAccounts, but are easier to administrate.
In order from most secure to least secure, the approaches are:
Grant a role to an application-specific service account (best practice)
This requires the application to specify a serviceAccountName in its pod spec,
and for the service account to be created (via the API, application manifest, kubectl create serviceaccount, etc.).
For example, grant read-only permission within "my-namespace" to the "my-sa" service account:
Many add-ons run as the
"default" service account in the kube-system namespace.
To allow those add-ons to run with super-user access, grant cluster-admin
permissions to the "default" service account in the kube-system namespace.
Caution:
Enabling this means the kube-system namespace contains Secrets
that grant super-user access to your cluster's API.
Grant a role to all service accounts in a namespace
If you want all applications in a namespace to have a role, no matter what service account they use,
you can grant a role to the service account group for that namespace.
For example, grant read-only permission within "my-namespace" to all service accounts in that namespace:
Grant super-user access to all service accounts cluster-wide (strongly discouraged)
If you don't care about partitioning permissions at all, you can grant super-user access to all service accounts.
Warning:
This allows any application full access to your cluster, and also grants
any user with read access to Secrets (or the ability to create any pod)
full access to your cluster.
Kubernetes clusters created before Kubernetes v1.22 include write access to
EndpointSlices (and the now-deprecated Endpoints API) in the aggregated "edit" and "admin" roles.
As a mitigation for CVE-2021-25740,
this access is not part of the aggregated roles in clusters that you create using
Kubernetes v1.22 or later.
Existing clusters that have been upgraded to Kubernetes v1.22 will not be
subject to this change. The CVE
announcement includes
guidance for restricting this access in existing clusters.
If you want new clusters to retain this level of access in the aggregated roles,
you can create the following ClusterRole:
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:annotations:kubernetes.io/description:|- Add endpoints write permissions to the edit and admin roles. This was
removed by default in 1.22 because of CVE-2021-25740. See
https://issue.k8s.io/103675. This can allow writers to direct LoadBalancer
or Ingress implementations to expose backend IPs that would not otherwise
be accessible, and can circumvent network policies or security controls
intended to prevent/isolate access to those backends.
EndpointSlices were never included in the edit or admin roles, so there
is nothing to restore for the EndpointSlice API.labels:rbac.authorization.k8s.io/aggregate-to-edit:"true"name:custom:aggregate-to-edit:endpoints# you can change this if you wishrules:- apiGroups:[""]resources:["endpoints"]verbs:["create","delete","deletecollection","patch","update"]
Upgrading from ABAC
Clusters that originally ran older Kubernetes versions often used
permissive ABAC policies, including granting full API access to all
service accounts.
Default RBAC policies grant scoped permissions to control-plane components, nodes,
and controllers, but grant no permissions to service accounts outside the kube-system namespace
(beyond the permissions given by API discovery roles).
While far more secure, this can be disruptive to existing workloads expecting to automatically receive API permissions.
Here are two approaches for managing this transition:
Parallel authorizers
Run both the RBAC and ABAC authorizers, and specify a policy file that contains
the legacy ABAC policy:
To explain that first command line option in detail: if earlier authorizers, such as Node,
deny a request, then the RBAC authorizer attempts to authorize the API request. If RBAC
also denies that API request, the ABAC authorizer is then run. This means that any request
allowed by either the RBAC or ABAC policies is allowed.
When the kube-apiserver is run with a log level of 5 or higher for the RBAC component
(--vmodule=rbac*=5 or --v=5), you can see RBAC denials in the API server log
(prefixed with RBAC).
You can use that information to determine which roles need to be granted to which users, groups, or service accounts.
Once you have granted roles to service accounts and workloads
are running with no RBAC denial messages in the server logs, you can remove the ABAC authorizer.
Permissive RBAC permissions
You can replicate a permissive ABAC policy using RBAC role bindings.
Warning:
The following policy allows ALL service accounts to act as cluster administrators.
Any application running in a container receives service account credentials automatically,
and could perform any action against the API, including viewing secrets and modifying permissions.
This is not a recommended policy.
After you have transitioned to use RBAC, you should adjust the access controls
for your cluster to ensure that these meet your information security needs.
3.5 - Using Node Authorization
Node authorization is a special-purpose authorization mode that specifically
authorizes API requests made by kubelets.
Overview
The Node authorizer allows a kubelet to perform API operations. This includes:
Read operations:
services
endpoints
nodes
pods
secrets, configmaps, persistent volume claims and persistent volumes related
to pods bound to the kubelet's node
FEATURE STATE:Kubernetes v1.34 [stable](enabled by default)
Kubelets are limited to reading their own Node objects, and only reading pods bound to their node.
Write operations:
nodes and node status (enable the NodeRestriction admission plugin to limit
a kubelet to modify its own node)
pods and pod status (enable the NodeRestriction admission plugin to limit a
kubelet to modify pods bound to itself)
the ability to create TokenReviews and SubjectAccessReviews for delegated
authentication/authorization checks
In future releases, the node authorizer may add or remove permissions to ensure
kubelets have the minimal set of permissions required to operate correctly.
In order to be authorized by the Node authorizer, kubelets must use a credential
that identifies them as being in the system:nodes group, with a username of
system:node:<nodeName>.
This group and user name format match the identity created for each kubelet as part of
kubelet TLS bootstrapping.
The value of <nodeName>must match precisely the name of the node as
registered by the kubelet. By default, this is the host name as provided by
hostname, or overridden via the
kubelet option--hostname-override. However, when using the --cloud-provider kubelet
option, the specific hostname may be determined by the cloud provider, ignoring
the local hostname and the --hostname-override option.
For specifics about how the kubelet determines the hostname, see the
kubelet options reference.
To enable the Node authorizer, start the API server
with the --authorization-config flag set to a file that includes the Node authorizer; for example:
To limit the API objects kubelets are able to write, enable the
NodeRestriction
admission plugin by starting the apiserver with
--enable-admission-plugins=...,NodeRestriction,...
Service account token audience restriction
FEATURE STATE:Kubernetes v1.33 [beta](enabled by default)
When the ServiceAccountNodeAudienceRestrictionfeature gate
is enabled and the NodeRestriction admission plugin is active, the kubelet can only
request service account tokens for audiences that are already referenced by pods running
on that node. This prevents a compromised node from obtaining tokens for arbitrary audiences.
The allowed audiences are determined from the pod spec:
The default API server audience (empty or the API server's configured audience).
Audiences set in projected service account token volume sources.
Audiences configured in CSI driver spec.tokenRequests for any CSI driver used by
the pod, whether through inline CSI volumes, PersistentVolumeClaim-backed volumes,
or ephemeral volumes.
You can grant kubelets permission to request tokens for audiences beyond what
the pod spec references. When the kubelet requests a token with an audience that
is not found in the pod spec, the NodeRestriction admission plugin checks whether
the kubelet is authorized by performing an authorization check with the following
attributes:
Attribute
Value
Verb
request-serviceaccounts-token-audience
API Group
(empty string, meaning the core API group)
Resource
The requested audience value
Name
The service account name
Namespace
The service account namespace
You can use standard RBAC rules to authorize these checks. The resources field
controls which audiences are allowed, and the resourceNames field controls which
service accounts the rule applies to.
For example, to allow the kubelet to request audience my-registry-audience for
a specific service account:
Omitting resourceNames allows the audience for any service account. Using a
wildcard ("*") for resources allows any audience:
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:node-audience-unrestrictedrules:- verbs:["request-serviceaccounts-token-audience"]apiGroups:[""]resources:["*"]# any audience# no resourceNames: any service account
Bind the ClusterRole to the system:nodes group to apply it to all kubelets:
This restriction is part of the NodeRestriction admission plugin and only applies to
node identities (kubelets). It does not restrict which audiences other callers of the
TokenRequest API can request. If you need to restrict other callers, consider using a ValidatingAdmissionPolicy.
Migration considerations
Kubelets outside the system:nodes group
Kubelets outside the system:nodes group would not be authorized by the Node
authorization mode, and would need to continue to be authorized via whatever
mechanism currently authorizes them.
The node admission plugin would not restrict requests from these kubelets.
Kubelets with undifferentiated usernames
In some deployments, kubelets have credentials that place them in the system:nodes group,
but do not identify the particular node they are associated with,
because they do not have a username in the system:node:... format.
These kubelets would not be authorized by the Node authorization mode,
and would need to continue to be authorized via whatever mechanism currently authorizes them.
The NodeRestriction admission plugin would ignore requests from these kubelets,
since the default node identifier implementation would not consider that a node identity.
3.6 - Webhook Mode
A WebHook is an HTTP callback: an HTTP POST that occurs when something happens; a simple event-notification via HTTP POST. A web application implementing WebHooks will POST a message to a URL when certain things happen.
When specified, mode Webhook causes Kubernetes to query an outside REST
service when determining user privileges.
Configuration File Format
Mode Webhook requires a file for HTTP configuration, specify by the
--authorization-webhook-config-file=SOME_FILENAME flag.
The configuration file uses the kubeconfig
file format. Within the file "users" refers to the API Server webhook and
"clusters" refers to the remote service.
A configuration example which uses HTTPS client auth:
# Kubernetes API versionapiVersion:v1# kind of the API objectkind:Config# clusters refers to the remote service.clusters:- name:name-of-remote-authz-servicecluster:# CA for verifying the remote service.certificate-authority:/path/to/ca.pem# URL of remote service to query. Must use 'https'. May not include parameters.server:https://authz.example.com/authorize# users refers to the API Server's webhook configuration.users:- name:name-of-api-serveruser:client-certificate:/path/to/cert.pem# cert for the webhook plugin to useclient-key:/path/to/key.pem # key matching the cert# kubeconfig files require a context. Provide one for the API Server.current-context:webhookcontexts:- context:cluster:name-of-remote-authz-serviceuser:name-of-api-servername:webhook
Request Payloads
When faced with an authorization decision, the API Server POSTs a JSON-
serialized authorization.k8s.io/v1beta1SubjectAccessReview object describing the
action. This object contains fields describing the user attempting to make the
request, and either details about the resource being accessed or requests
attributes.
Note that webhook API objects are subject to the same versioning compatibility rules
as other Kubernetes API objects. Implementers should be aware of looser
compatibility promises for beta objects and check the "apiVersion" field of the
request to ensure correct deserialization. Additionally, the API Server must
enable the authorization.k8s.io/v1beta1 API extensions group (--runtime-config=authorization.k8s.io/v1beta1=true).
The remote service is expected to fill the status field of
the request and respond to either allow or disallow access. The response body's
spec field is ignored and may be omitted. A permissive response would return:
The first method is preferred in most cases, and indicates the authorization
webhook does not allow, or has "no opinion" about the request, but if other
authorizers are configured, they are given a chance to allow the request.
If there are no other authorizers, or none of them allow the request, the
request is forbidden. The webhook would return:
{"apiVersion":"authorization.k8s.io/v1beta1","kind":"SubjectAccessReview","status":{"allowed":false,"reason":"user does not have read access to the namespace"}}
The second method denies immediately, short-circuiting evaluation by other
configured authorizers. This should only be used by webhooks that have
detailed knowledge of the full authorizer configuration of the cluster.
The webhook would return:
{"apiVersion":"authorization.k8s.io/v1beta1","kind":"SubjectAccessReview","status":{"allowed":false,"denied":true,"reason":"user does not have read access to the namespace"}}
FEATURE STATE:Kubernetes v1.34 [stable](enabled by default)
When calling out to an authorization webhook, Kubernetes passes
label and field selectors in the request to the authorization webhook.
The authorization webhook can make authorization decisions
informed by the scoped field and label selectors, if it wishes.
The SubjectAccessReview API documentation
gives guidelines for how these fields should be interpreted and handled by authorization webhooks,
specifically using the parsed requirements rather than the raw selector strings,
and how to handle unrecognized operators safely.
Non-resource paths include: /api, /apis, /metrics,
/logs, /debug, /healthz, /livez, /openapi/v2, /readyz, and
/version. Clients require access to /api, /api/*, /apis, /apis/*,
and /version to discover what resources and versions are present on the server.
Access to other non-resource paths can be disallowed without restricting access
to the REST api.
Attribute-based access control (ABAC) defines an access control paradigm whereby access rights are granted
to users through the use of policies which combine attributes together.
Policy File Format
To enable ABAC mode, specify --authorization-policy-file=SOME_FILENAME and --authorization-mode=ABAC
on startup.
The file format is one JSON object per line. There
should be no enclosing list or map, only one map per line.
Each line is a "policy object", where each such object is a map with the following
properties:
Versioning properties:
apiVersion, type string; valid values are "abac.authorization.kubernetes.io/v1beta1". Allows versioning
and conversion of the policy format.
kind, type string: valid values are "Policy". Allows versioning and conversion of the policy format.
spec property set to a map with the following properties:
Subject-matching properties:
user, type string; the user-string from --token-auth-file. If you specify user, it must match the
username of the authenticated user.
group, type string; if you specify group, it must match one of the groups of the authenticated user.
system:authenticated matches all authenticated requests. system:unauthenticated matches all
unauthenticated requests.
Resource-matching properties:
apiGroup, type string; an API group.
Ex: apps, networking.k8s.io
Wildcard: * matches all API groups.
namespace, type string; a namespace.
Ex: kube-system
Wildcard: * matches all resource requests.
resource, type string; a resource type
Ex: pods, deployments
Wildcard: * matches all resource requests.
Non-resource-matching properties:
nonResourcePath, type string; non-resource request paths.
Ex: /version or /apis
Wildcard:
* matches all non-resource requests.
/foo/* matches all subpaths of /foo/.
readonly, type boolean, when true, means that the Resource-matching policy only applies to get, list,
and watch operations, Non-resource-matching policy only applies to get operation.
Note:
An unset property is the same as a property set to the zero value for its type
(e.g. empty string, 0, false). However, unset should be preferred for
readability.
In the future, policies may be expressed in a JSON format, and managed via a
REST interface.
Authorization Algorithm
A request has attributes which correspond to the properties of a policy object.
When a request is received, the attributes are determined. Unknown attributes
are set to the zero value of its type (e.g. empty string, 0, false).
A property set to "*" will match any value of the corresponding attribute.
The tuple of attributes is checked for a match against every policy in the
policy file. If at least one line matches the request attributes, then the
request is authorized (but may fail later validation).
To permit any authenticated user to do something, write a policy with the
group property set to "system:authenticated".
To permit any unauthenticated user to do something, write a policy with the
group property set to "system:unauthenticated".
To permit a user to do anything, write a policy with the apiGroup, namespace,
resource, and nonResourcePath properties set to "*".
Kubectl
Kubectl uses the /api and /apis endpoints of apiserver to discover
served resource types, and validates objects sent to the API by create/update
operations using schema information located at /openapi/v2.
When using ABAC authorization, those special resources have to be explicitly
exposed via the nonResourcePath property in a policy (see examples below):
/api, /api/*, /apis, and /apis/* for API version negotiation.
/version for retrieving the server version via kubectl version.
/swaggerapi/* for create/update operations.
To inspect the HTTP calls involved in a specific kubectl operation you can turn
up the verbosity:
Creating a new namespace leads to the creation of a new service account in the following format:
system:serviceaccount:<namespace>:default
For example, if you wanted to grant the default service account (in the kube-system namespace) full
privilege to the API using ABAC, you would add this line to your policy file:
The apiserver will need to be restarted to pick up the new policy lines.
3.8 - Admission Control in Kubernetes
This page provides an overview of admission controllers.
An admission controller is a piece of code that intercepts requests to the
Kubernetes API server prior to persistence of the resource, but after the request
is authenticated and authorized.
Several important features of Kubernetes require an admission controller to be enabled in order
to properly support the feature. As a result, a Kubernetes API server that is not properly
configured with the right set of admission controllers is an incomplete server that will not
support all the features you expect.
What are they?
Admission controllers are code within the Kubernetes
API server that check the
data arriving in a request to modify a resource.
Admission controllers apply to requests that create, delete, or modify objects.
Admission controllers can also block custom verbs, such as a request to connect to a
pod via an API server proxy. Admission controllers do not (and cannot) block requests
to read (get, watch or list) objects, because reads bypass the admission
control layer.
Admission control mechanisms may be validating, mutating, or both. Mutating
controllers may modify the data for the resource being modified; validating controllers may not.
The admission controllers in Kubernetes 1.36 consist of the
list below, are compiled into the
kube-apiserver binary, and may only be configured by the cluster
administrator.
Admission control extension points
Within the full list, there are three
special controllers:
MutatingAdmissionWebhook,
ValidatingAdmissionWebhook, and
ValidatingAdmissionPolicy.
The two webhook controllers execute the mutating and validating (respectively)
admission control webhooks
which are configured in the API. ValidatingAdmissionPolicy provides a way to embed
declarative validation code within the API, without relying on any external HTTP
callouts.
You can use these three admission controllers to customize cluster behavior at
admission time.
Admission control phases
The admission control process proceeds in two phases. In the first phase,
mutating admission controllers are run. In the second phase, validating
admission controllers are run. Note again that some of the controllers are
both.
If any of the controllers in either phase reject the request, the entire
request is rejected immediately and an error is returned to the end-user.
Finally, in addition to sometimes mutating the object in question, admission
controllers may sometimes have side effects, that is, mutate related
resources as part of request processing. Incrementing quota usage is the
canonical example of why this is necessary. Any such side-effect needs a
corresponding reclamation or reconciliation process, as a given admission
controller does not know for sure that a given request will pass all of the
other admission controllers.
The ordering of these calls can be seen below.
Why do I need them?
Several important features of Kubernetes require an admission controller to be enabled in order
to properly support the feature. As a result, a Kubernetes API server that is not properly
configured with the right set of admission controllers is an incomplete server and will not
support all the features you expect.
How do I turn on an admission controller?
The Kubernetes API server flag enable-admission-plugins takes a comma-delimited list of admission control plugins to invoke prior to modifying objects in the cluster.
For example, the following command line enables the NamespaceLifecycle and the LimitRanger
admission control plugins:
Depending on the way your Kubernetes cluster is deployed and how the API server is
started, you may need to apply the settings in different ways. For example, you may
have to modify the systemd unit file if the API server is deployed as a systemd
service, you may modify the manifest file for the API server if Kubernetes is deployed
in a self-hosted way.
How do I turn off an admission controller?
The Kubernetes API server flag disable-admission-plugins takes a comma-delimited list of admission control plugins to be disabled, even if they are in the list of plugins enabled by default.
This admission controller allows all pods into the cluster. It is deprecated because
its behavior is the same as if there were no admission controller at all.
AlwaysDeny
FEATURE STATE:Kubernetes v1.13 [deprecated]
Type: Validating.
Rejects all requests. AlwaysDeny is deprecated as it has no real meaning.
AlwaysPullImages
Type: Mutating and Validating.
This admission controller modifies every new Pod to force the image pull policy to Always. This is useful in a
multitenant cluster so that users can be assured that their private images can only be used by those
who have the credentials to pull them. Without this admission controller, once an image has been pulled to a
node, any pod from any user can use it by knowing the image's name (assuming the Pod is
scheduled onto the right node), without any authorization check against the image. When this admission controller
is enabled, images are always pulled prior to starting containers, which means valid credentials are
required.
CertificateApproval
Type: Validating.
This admission controller observes requests to approve CertificateSigningRequest resources and performs additional
authorization checks to ensure the approving user has permission to approve certificate requests with the
spec.signerName requested on the CertificateSigningRequest resource.
See Certificate Signing Requests for more
information on the permissions required to perform different actions on CertificateSigningRequest resources.
CertificateSigning
Type: Validating.
This admission controller observes updates to the status.certificate field of CertificateSigningRequest resources
and performs an additional authorization checks to ensure the signing user has permission to sign certificate
requests with the spec.signerName requested on the CertificateSigningRequest resource.
See Certificate Signing Requests for more
information on the permissions required to perform different actions on CertificateSigningRequest resources.
CertificateSubjectRestriction
Type: Validating.
This admission controller observes creation of CertificateSigningRequest resources that have a spec.signerName
of kubernetes.io/kube-apiserver-client. It rejects any request that specifies a 'group' (or 'organization attribute')
of system:masters.
DefaultIngressClass
Type: Mutating.
This admission controller observes creation of Ingress objects that do not request any specific
ingress class and automatically adds a default ingress class to them. This way, users that do not
request any special ingress class do not need to care about them at all and they will get the
default one.
This admission controller does not do anything when no default ingress class is configured. When more than one ingress
class is marked as default, it rejects any creation of Ingress with an error and an administrator
must revisit their IngressClass objects and mark only one as default (with the annotation
"ingressclass.kubernetes.io/is-default-class"). This admission controller ignores any Ingress
updates; it acts only on creation.
See the Ingress documentation for more about ingress
classes and how to mark one as default.
DefaultStorageClass
Type: Mutating.
This admission controller observes creation of PersistentVolumeClaim objects that do not request any specific storage class
and automatically adds a default storage class to them.
This way, users that do not request any special storage class do not need to care about them at all and they
will get the default one.
This admission controller does nothing when no default StorageClass exists. When more than one storage
class is marked as default, and you then create a PersistentVolumeClaim with no storageClassName set,
Kubernetes uses the most recently created default StorageClass.
When a PersistentVolumeClaim is created with a specified volumeName, it remains in a pending state
if the static volume's storageClassName does not match the storageClassName on the PersistentVolumeClaim
after any default StorageClass is applied to it.
This admission controller ignores any PersistentVolumeClaim updates; it acts only on creation.
See persistent volume documentation about persistent volume claims and
storage classes and how to mark a storage class as default.
DefaultTolerationSeconds
Type: Mutating.
This admission controller sets the default forgiveness toleration for pods to tolerate
the taints notready:NoExecute and unreachable:NoExecute based on the k8s-apiserver input parameters
default-not-ready-toleration-seconds and default-unreachable-toleration-seconds if the pods don't already
have toleration for taints node.kubernetes.io/not-ready:NoExecute or
node.kubernetes.io/unreachable:NoExecute.
The default value for default-not-ready-toleration-seconds and default-unreachable-toleration-seconds is 5 minutes.
DenyServiceExternalIPs
Type: Validating.
This admission controller rejects all net-new usage of the Service field externalIPs. This
feature is very powerful (allows network traffic interception) and not well
controlled by policy. When enabled, users of the cluster may not create new
Services which use externalIPs and may not add new values to externalIPs on
existing Service objects. Existing uses of externalIPs are not affected,
and users may remove values from externalIPs on existing Service objects.
Most users do not need this feature at all, and cluster admins should consider disabling it.
Clusters that do need to use this feature should consider using some custom policy to manage usage
of it.
This admission controller is disabled by default.
EventRateLimit
FEATURE STATE:Kubernetes v1.13 [alpha]
Type: Validating.
This admission controller mitigates the problem where the API server gets flooded by
requests to store new Events. The cluster admin can specify event rate limits by:
Enabling the EventRateLimit admission controller;
Referencing an EventRateLimit configuration file from the file provided to the API
server's command line flag --admission-control-config-file:
This plug-in facilitates creation of dedicated nodes with extended resources.
If operators want to create dedicated nodes with extended resources (like GPUs, FPGAs etc.), they are expected to
taint the node with the extended resource
name as the key. This admission controller, if enabled, automatically
adds tolerations for such taints to pods requesting extended resources, so users don't have to manually
add these tolerations.
This admission controller is disabled by default.
ImagePolicyWebhook
Type: Validating.
The ImagePolicyWebhook admission controller allows a backend webhook to make admission decisions.
This admission controller is disabled by default.
Configuration file format
ImagePolicyWebhook uses a configuration file to set options for the behavior of the backend.
This file may be json or yaml and has the following format:
imagePolicy:kubeConfigFile:/path/to/kubeconfig/for/backend# time in s to cache approvalallowTTL:50# time in s to cache denialdenyTTL:50# time in ms to wait between retriesretryBackoff:500# determines behavior if the webhook backend failsdefaultAllow:true
Reference the ImagePolicyWebhook configuration file from the file provided to the API server's command line flag --admission-control-config-file:
The ImagePolicyWebhook config file must reference a
kubeconfig
formatted file which sets up the connection to the backend.
It is required that the backend communicate over TLS.
The kubeconfig file's cluster field must point to the remote service, and the user field
must contain the returned authorizer.
# clusters refers to the remote service.clusters:- name:name-of-remote-imagepolicy-servicecluster:certificate-authority:/path/to/ca.pem # CA for verifying the remote service.server:https://images.example.com/policy# URL of remote service to query. Must use 'https'.# users refers to the API server's webhook configuration.users:- name:name-of-api-serveruser:client-certificate:/path/to/cert.pem# cert for the webhook admission controller to useclient-key:/path/to/key.pem # key matching the cert
For additional HTTP configuration, refer to the
kubeconfig documentation.
Request payloads
When faced with an admission decision, the API Server POSTs a JSON serialized
imagepolicy.k8s.io/v1alpha1ImageReview object describing the action.
This object contains fields describing the containers being admitted, as well as
any pod annotations that match *.image-policy.k8s.io/*.
Note:
The webhook API objects are subject to the same versioning compatibility rules
as other Kubernetes API objects. Implementers should be aware of looser compatibility
promises for alpha objects and check the apiVersion field of the request to
ensure correct deserialization.
Additionally, the API Server must enable the imagepolicy.k8s.io/v1alpha1 API extensions
group (--runtime-config=imagepolicy.k8s.io/v1alpha1=true).
The remote service is expected to fill the status field of the request and
respond to either allow or disallow access. The response body's spec field is ignored, and
may be omitted. A permissive response would return:
{"apiVersion":"imagepolicy.k8s.io/v1alpha1","kind":"ImageReview","status":{"allowed":false,"reason":"image currently blacklisted"}}
Note:
ImageReview objects will include all images in Pods intended to be executed as
containers. This covers images specified as part of the containers,
initContainers, or ephemeralContainers fields in a Pod specification. As a
result, images included under image volumes are not in scope for the
ImagePolicyWebhook.
All annotations on a Pod that match *.image-policy.k8s.io/* are sent to the webhook.
Sending annotations allows users who are aware of the image policy backend to
send extra information to it, and for different backends implementations to
accept different information.
Examples of information you might put here are:
request to "break glass" to override a policy, in case of emergency.
a ticket number from a ticket system that documents the break-glass request
provide a hint to the policy server as to the imageID of the image being provided, to save it a lookup
In any case, the annotations are provided by the user and are not validated by Kubernetes in any way.
LimitPodHardAntiAffinityTopology
Type: Validating.
This admission controller denies any pod that defines an AntiAffinity topology key other than
kubernetes.io/hostname in requiredDuringSchedulingIgnoredDuringExecution.
This admission controller is disabled by default.
LimitRanger
Type: Mutating and Validating.
This admission controller will observe the incoming request and ensure that it does not violate
any of the constraints enumerated in the LimitRange object in a Namespace. If you are using
LimitRange objects in your Kubernetes deployment, you MUST use this admission controller to
enforce those constraints. LimitRanger can also be used to apply default resource requests to Pods
that don't specify any; currently, the default LimitRanger applies a 0.1 CPU requirement to all
Pods in the default namespace.
This admission controller calls any mutating webhooks which match the request. Matching
webhooks are called in serial; each one may modify the object if it desires.
This admission controller (as implied by the name) only runs in the mutating phase.
If a webhook called by this has side effects (for example, decrementing quota) it
must have a reconciliation system, as it is not guaranteed that subsequent
webhooks or validating admission controllers will permit the request to finish.
If you disable the MutatingAdmissionWebhook, you must also disable the
MutatingWebhookConfiguration object in the admissionregistration.k8s.io/v1
group/version via the --runtime-config flag, both are on by default.
Use caution when authoring and installing mutating webhooks
Users may be confused when the objects they try to create are different from
what they get back.
Built in control loops may break when the objects they try to create are
different when read back.
Setting originally unset fields is less likely to cause problems than
overwriting fields set in the original request. Avoid doing the latter.
Future changes to control loops for built-in resources or third-party resources
may break webhooks that work well today. Even when the webhook installation API
is finalized, not all possible webhook behaviors will be guaranteed to be supported
indefinitely.
NamespaceAutoProvision
Type: Mutating.
This admission controller examines all incoming requests on namespaced resources and checks
if the referenced namespace does exist.
It creates a namespace if it cannot be found.
This admission controller is useful in deployments that do not want to restrict creation of
a namespace prior to its usage.
NamespaceExists
Type: Validating.
This admission controller checks all requests on namespaced resources other than Namespace itself.
If the namespace referenced from a request doesn't exist, the request is rejected.
NamespaceLifecycle
Type: Validating.
This admission controller enforces that a Namespace that is undergoing termination cannot have
new objects created in it, and ensures that requests in a non-existent Namespace are rejected.
This admission controller also prevents deletion of three system reserved namespaces default,
kube-system, kube-public.
A Namespace deletion kicks off a sequence of operations that remove all objects (pods, services,
etc.) in that namespace. In order to enforce integrity of that process, we strongly recommend
running this admission controller.
NodeDeclaredFeatureValidator
FEATURE STATE:Kubernetes v1.36 [beta](enabled by default)
Type: Validating.
This admission controller intercepts writes to bound Pods, to ensure that the
changes are compatible with the features declared by the node where the Pod is
currently running. It uses the .status.declaredFeatures field of the Node to
determine the set of enabled features. If a Pod update requires a feature that
is not listed in the features of its current node, the admission controller
will reject the update request. This prevents runtime failures due to feature
mismatch after a Pod has been scheduled.
This admission controller is enabled by
default if the NodeDeclaredFeatures feature gate is enabled.
NodeRestriction
Type: Validating.
This admission controller limits the Node and Pod objects a kubelet can modify. In order to be limited by this admission controller,
kubelets must use credentials in the system:nodes group, with a username in the form system:node:<nodeName>.
Such kubelets will only be allowed to modify their own Node API object, and only modify Pod API objects that are bound to their node.
kubelets are not allowed to update or remove taints from their Node API object.
The NodeRestriction admission plugin prevents kubelets from deleting their Node API object,
and enforces kubelet modification of labels under the kubernetes.io/ or k8s.io/ prefixes as follows:
Forbidden (Kubelets are blocked from modifying these):
Labels with a node-restriction.kubernetes.io/ prefix. This prefix is reserved for administrators to label Node objects for workload isolation.
Labels with a node-role.kubernetes.io/ prefix (for example: node-role.kubernetes.io/control-plane). These are restricted to prevent unprivileged nodes from self-declaring cluster roles.
Reserved:
Use of any other labels under the kubernetes.io or k8s.io prefixes by kubelets is reserved.
The NodeRestriction admission plugin generally disallows these to prevent unauthorized self-labeling,
but may allow additional labels under these prefixes in the future as part of future features.
When the ServiceAccountNodeAudienceRestrictionfeature gate
is enabled, this admission plugin also restricts the audiences for which a kubelet can
request service account tokens via the TokenRequest API. The kubelet can only request
tokens for audiences already referenced by pods on that node (through projected service
account token volumes or CSI driver token requests), or for audiences explicitly granted
through RBAC using the request-serviceaccounts-token-audience verb. For more details,
see Service account token audience restriction.
Future versions may add additional restrictions to ensure kubelets have the minimal set of
permissions required to operate correctly.
OwnerReferencesPermissionEnforcement
Type: Validating.
This admission controller protects the access to the metadata.ownerReferences of an object
so that only users with delete permission to the object can change it.
This admission controller also protects the access to metadata.ownerReferences[x].blockOwnerDeletion
of an object, so that only users with update permission to the finalizers
subresource of the referenced owner can change it.
PersistentVolumeClaimResize
FEATURE STATE:Kubernetes v1.24 [stable]
Type: Validating.
This admission controller implements additional validations for checking incoming
PersistentVolumeClaim resize requests.
Enabling the PersistentVolumeClaimResize admission controller is recommended.
This admission controller prevents resizing of all claims by default unless a claim's StorageClass
explicitly enables resizing by setting allowVolumeExpansion to true.
For example: all PersistentVolumeClaims created from the following StorageClass support volume expansion:
This admission controller defaults and limits what node selectors may be used within a namespace
by reading a namespace annotation and a global configuration.
This admission controller is disabled by default.
Configuration file format
PodNodeSelector uses a configuration file to set options for the behavior of the backend.
Note that the configuration file format will move to a versioned file in a future release.
This file may be json or yaml and has the following format:
This admission controller has the following behavior:
If the Namespace has an annotation with a key scheduler.alpha.kubernetes.io/node-selector,
use its value as the node selector.
If the namespace lacks such an annotation, use the clusterDefaultNodeSelector defined in the
PodNodeSelector plugin configuration file as the node selector.
Evaluate the pod's node selector against the namespace node selector for conflicts. Conflicts
result in rejection.
Evaluate the pod's node selector against the namespace-specific allowed selector defined the
plugin configuration file. Conflicts result in rejection.
Note:
PodNodeSelector allows forcing pods to run on specifically labeled nodes. Also see the PodTolerationRestriction
admission plugin, which allows preventing pods from running on specifically tainted nodes.
PodSecurity
FEATURE STATE:Kubernetes v1.25 [stable]
Type: Validating.
The PodSecurity admission controller checks new Pods before they are
admitted, determines if it should be admitted based on the requested security context and the restrictions on permitted
Pod Security Standards
for the namespace that the Pod would be in.
PodSecurity replaced an older admission controller named PodSecurityPolicy.
PodTolerationRestriction
FEATURE STATE:Kubernetes v1.7 [alpha]
Type: Mutating and Validating.
The PodTolerationRestriction admission controller verifies any conflict between tolerations of a
pod and the tolerations of its namespace.
It rejects the pod request if there is a conflict.
It then merges the tolerations annotated on the namespace into the tolerations of the pod.
The resulting tolerations are checked against a list of allowed tolerations annotated to the namespace.
If the check succeeds, the pod request is admitted otherwise it is rejected.
If the namespace of the pod does not have any associated default tolerations or allowed
tolerations annotated, the cluster-level default tolerations or cluster-level list of allowed tolerations are used
instead if they are specified.
Tolerations to a namespace are assigned via the scheduler.alpha.kubernetes.io/defaultTolerations annotation key.
The list of allowed tolerations can be added via the scheduler.alpha.kubernetes.io/tolerationsWhitelist annotation key.
FEATURE STATE:Kubernetes v1.35 [beta](enabled by default)
Type: Mutating
The PodTopologyLabels admission controller mutates the pods/binding subresources
for all pods bound to a Node, adding topology labels matching those of the bound Node.
This allows Node topology labels to be available as pod labels,
which can be surfaced to running containers using the
Downward API.
The labels available as a result of this controller are the
topology.kubernetes.io/region and
topology.kuberentes.io/zone labels.
Note:
If any mutating admission webhook adds or modifies labels of the pods/binding subresource,
these changes will propagate to pod labels as a result of this controller,
overwriting labels with conflicting keys.
This admission controller is enabled when the PodTopologyLabelsAdmission feature gate is enabled.
Priority
Type: Mutating and Validating.
The priority admission controller uses the priorityClassName field and populates the integer
value of the priority.
If the priority class is not found, the Pod is rejected.
ResourceQuota
Type: Validating.
This admission controller will observe the incoming request and ensure that it does not violate
any of the constraints enumerated in the ResourceQuota object in a Namespace. If you are
using ResourceQuota objects in your Kubernetes deployment, you MUST use this admission
controller to enforce quota constraints.
If you define a RuntimeClass with Pod overhead
configured, this admission controller checks incoming Pods.
When enabled, this admission controller rejects any Pod create requests
that have the overhead already set.
For Pods that have a RuntimeClass configured and selected in their .spec,
this admission controller sets .spec.overhead in the Pod based on the value
defined in the corresponding RuntimeClass.
This admission controller implements automation for
serviceAccounts.
The Kubernetes project strongly recommends enabling this admission controller.
You should enable this admission controller if you intend to make any use of Kubernetes
ServiceAccount objects.
To enhance the security measures around Secrets, use separate namespaces to isolate access to mounted secrets.
StorageObjectInUseProtection
Type: Mutating.
The StorageObjectInUseProtection plugin adds the kubernetes.io/pvc-protection or kubernetes.io/pv-protection
finalizers to newly created Persistent Volume Claims (PVCs) or Persistent Volumes (PV).
In case a user deletes a PVC or PV the PVC or PV is not removed until the finalizer is removed
from the PVC or PV by PVC or PV Protection Controller.
Refer to the
Storage Object in Use Protection
for more detailed information.
TaintNodesByCondition
Type: Mutating.
This admission controller taints newly created
Nodes as NotReady and NoSchedule. That tainting avoids a race condition that could cause Pods
to be scheduled on new Nodes before their taints were updated to accurately reflect their reported
conditions.
ValidatingAdmissionPolicy
Type: Validating.
This admission controller implements the CEL validation for incoming matched requests.
It is enabled when both feature gate validatingadmissionpolicy and admissionregistration.k8s.io/v1alpha1 group/version are enabled.
If any of the ValidatingAdmissionPolicy fails, the request fails.
ValidatingAdmissionWebhook
Type: Validating.
This admission controller calls any validating webhooks which match the request. Matching
webhooks are called in parallel; if any of them rejects the request, the request
fails. This admission controller only runs in the validation phase; the webhooks it calls may not
mutate the object, as opposed to the webhooks called by the MutatingAdmissionWebhook admission controller.
If a webhook called by this has side effects (for example, decrementing quota) it
must have a reconciliation system, as it is not guaranteed that subsequent
webhooks or other validating admission controllers will permit the request to finish.
If you disable the ValidatingAdmissionWebhook, you must also disable the
ValidatingWebhookConfiguration object in the admissionregistration.k8s.io/v1
group/version via the --runtime-config flag.
Is there a recommended set of admission controllers to use?
Yes. The recommended admission controllers are enabled by default
(shown here),
so you do not need to explicitly specify them.
You can enable additional admission controllers beyond the default set using the
--enable-admission-plugins flag (order doesn't matter).
3.9 - Dynamic Admission Control
In addition to compiled-in admission plugins,
admission plugins can be developed as extensions and run as webhooks configured at runtime.
This page describes how to build, configure, use, and monitor admission webhooks.
What are admission webhooks?
Admission webhooks are HTTP callbacks that receive admission requests and do
something with them. You can define two types of admission webhooks,
validating admission webhook
and
mutating admission webhook.
Mutating admission webhooks are invoked first, and can modify objects sent to the API server to enforce custom defaults.
After all object modifications are complete, and after the incoming object is validated by the API server,
validating admission webhooks are invoked and can reject requests to enforce custom policies.
Note:
Admission webhooks that need to guarantee they see the final state of the object in order to enforce policy
should use a validating admission webhook, since objects can be modified after being seen by mutating webhooks.
Experimenting with admission webhooks
Admission webhooks are essentially part of the cluster control-plane. You should
write and deploy them with great caution. Please read the
user guides
for instructions if you intend to write/deploy production-grade admission webhooks.
In the following, we describe how to quickly experiment with admission webhooks.
Prerequisites
Ensure that MutatingAdmissionWebhook and ValidatingAdmissionWebhook
admission controllers are enabled.
Here
is a recommended set of admission controllers to enable in general.
Ensure that the admissionregistration.k8s.io/v1 API is enabled.
Write an admission webhook server
Please refer to the implementation of the admission webhook server
that is validated in a Kubernetes e2e test. The webhook handles the
AdmissionReview request sent by the API servers, and sends back its decision
as an AdmissionReview object in the same version it received.
See the webhook request section for details on the data sent to webhooks.
See the webhook response section for the data expected from webhooks.
The example admission webhook server leaves the ClientAuth field
empty,
which defaults to NoClientCert. This means that the webhook server does not
authenticate the identity of the clients, supposedly API servers. If you need
mutual TLS or other ways to authenticate the clients, see
how to authenticate API servers.
Deploy the admission webhook service
The webhook server in the e2e test is deployed in the Kubernetes cluster, via
the deployment API.
The test also creates a service
as the front-end of the webhook server. See
code.
You may also deploy your webhooks outside of the cluster. You will need to update
your webhook configurations accordingly.
The following is an example ValidatingWebhookConfiguration, a mutating webhook configuration is similar.
See the webhook configuration section for details about each config field.
You must replace the <CA_BUNDLE> in the above example by a valid CA bundle
which is a PEM-encoded (field value is Base64 encoded) CA bundle for validating the webhook's server certificate.
The scope field specifies if only cluster-scoped resources ("Cluster") or namespace-scoped
resources ("Namespaced") will match this rule. "∗" means that there are no scope restrictions.
Note:
When using clientConfig.service, the server cert must be valid for
<svc_name>.<svc_namespace>.svc.
Note:
Default timeout for a webhook call is 10 seconds,
You can set the timeout and it is encouraged to use a short timeout for webhooks.
If the webhook call times out, the request is handled according to the webhook's
failure policy.
When an API server receives a request that matches one of the rules, the
API server sends an admissionReview request to webhook as specified in the
clientConfig.
After you create the webhook configuration, the system will take a few seconds
to honor the new configuration.
Authenticate API servers
If your admission webhooks require authentication, you can configure the
API servers to use basic auth, bearer token, or a cert to authenticate itself to
the webhooks. There are three steps to complete the configuration.
When starting the API server, specify the location of the admission control
configuration file via the --admission-control-config-file flag.
In the admission control configuration file, specify where the
MutatingAdmissionWebhook controller and ValidatingAdmissionWebhook controller
should read the credentials. The credentials are stored in kubeConfig files
(yes, the same schema that's used by kubectl), so the field name is
kubeConfigFile. Here is an example admission control configuration file:
apiVersion:v1kind:Configusers:# name should be set to the DNS name of the service or the host (including port) of the URL the webhook is configured to speak to.# If a non-443 port is used for services, it must be included in the name when configuring 1.16+ API servers.## For a webhook configured to speak to a service on the default port (443), specify the DNS name of the service:# - name: webhook1.ns1.svc# user: ...## For a webhook configured to speak to a service on non-default port (e.g. 8443), specify the DNS name and port of the service in 1.16+:# - name: webhook1.ns1.svc:8443# user: ...# and optionally create a second stanza using only the DNS name of the service for compatibility with 1.15 API servers:# - name: webhook1.ns1.svc# user: ...## For webhooks configured to speak to a URL, match the host (and port) specified in the webhook's URL. Examples:# A webhook with `url: https://www.example.com`:# - name: www.example.com# user: ...## A webhook with `url: https://www.example.com:443`:# - name: www.example.com:443# user: ...## A webhook with `url: https://www.example.com:8443`:# - name: www.example.com:8443# user: ...#- name:'webhook1.ns1.svc'user:client-certificate-data:"<pem encoded certificate>"client-key-data:"<pem encoded key>"# The `name` supports using * to wildcard-match prefixing segments.- name:'*.webhook-company.org'user:password:"<password>"username:"<name>"# '*' is the default match.- name:'*'user:token:"<token>"
Of course you need to set up the webhook server to handle these authentication requests.
Webhook request and response
Request
Webhooks are sent as POST requests, with Content-Type: application/json,
with an AdmissionReview API object in the admission.k8s.io API group
serialized to JSON as the body.
Webhooks can specify what versions of AdmissionReview objects they accept
with the admissionReviewVersions field in their configuration:
admissionReviewVersions is a required field when creating webhook configurations.
Webhooks are required to support at least one AdmissionReview
version understood by the current and previous API server.
API servers send the first AdmissionReview version in the admissionReviewVersions list they support.
If none of the versions in the list are supported by the API server, the configuration will not be allowed to be created.
If an API server encounters a webhook configuration that was previously created and does not support any of the AdmissionReview
versions the API server knows how to send, attempts to call to the webhook will fail and be subject to the failure policy.
This example shows the data contained in an AdmissionReview object
for a request to update the scale subresource of an apps/v1Deployment:
{"apiVersion": "admission.k8s.io/v1","kind": "AdmissionReview","request": {# Random uid uniquely identifying this admission call"uid": "705ab4f5-6393-11e8-b7cc-42010a800002",# Fully-qualified group/version/kind of the incoming object"kind": {"group": "autoscaling","version": "v1","kind": "Scale"},# Fully-qualified group/version/kind of the resource being modified"resource": {"group": "apps","version": "v1","resource": "deployments"},# Subresource, if the request is to a subresource"subResource": "scale",# Fully-qualified group/version/kind of the incoming object in the original request to the API server# This only differs from `kind` if the webhook specified `matchPolicy: Equivalent` and the original# request to the API server was converted to a version the webhook registered for"requestKind": {"group": "autoscaling","version": "v1","kind": "Scale"},# Fully-qualified group/version/kind of the resource being modified in the original request to the API server# This only differs from `resource` if the webhook specified `matchPolicy: Equivalent` and the original# request to the API server was converted to a version the webhook registered for"requestResource": {"group": "apps","version": "v1","resource": "deployments"},# Subresource, if the request is to a subresource# This only differs from `subResource` if the webhook specified `matchPolicy: Equivalent` and the original# request to the API server was converted to a version the webhook registered for"requestSubResource": "scale",# Name of the resource being modified"name": "my-deployment",# Namespace of the resource being modified, if the resource is namespaced (or is a Namespace object)"namespace": "my-namespace",# operation can be CREATE, UPDATE, DELETE, or CONNECT"operation": "UPDATE","userInfo": {# Username of the authenticated user making the request to the API server"username": "admin",# UID of the authenticated user making the request to the API server"uid": "014fbff9a07c",# Group memberships of the authenticated user making the request to the API server"groups": ["system:authenticated","my-admin-group"],# Arbitrary extra info associated with the user making the request to the API server# This is populated by the API server authentication layer"extra": {"some-key": ["some-value1","some-value2"]}},# object is the new object being admitted.

Response
Webhooks respond with a 200 HTTP status code, Content-Type: application/json,
and a body containing an AdmissionReview object (in the same version they were sent),
with the response stanza populated, serialized to JSON.
At a minimum, the response stanza must contain the following fields:
uid, copied from the request.uid sent to the webhook
allowed, either set to true or false
Example of a minimal response from a webhook to allow a request:
{"apiVersion":"admission.k8s.io/v1","kind":"AdmissionReview","response":{"uid":"<value from request.uid>","allowed":true}}
Example of a minimal response from a webhook to forbid a request:
{"apiVersion":"admission.k8s.io/v1","kind":"AdmissionReview","response":{"uid":"<value from request.uid>","allowed":false}}
When rejecting a request, the webhook can customize the http code and message returned to the user
using the status field. The specified status object is returned to the user.
See the API documentation
for details about the status type.
Example of a response to forbid a request, customizing the HTTP status code and message presented to the user:
{"apiVersion":"admission.k8s.io/v1","kind":"AdmissionReview","response":{"uid":"<value from request.uid>","allowed":false,"status":{"code":403,"message":"You cannot do this because it is Tuesday and your name starts with A"}}}
When allowing a request, a mutating admission webhook may optionally modify the incoming object as well.
This is done using the patch and patchType fields in the response.
The only currently supported patchType is JSONPatch.
See JSON patch documentation for more details.
For patchType: JSONPatch, the patch field contains a base64-encoded array of JSON patch operations.
As an example, a single patch operation that would set spec.replicas would be
[{"op": "add", "path": "/spec/replicas", "value": 3}]
Base64-encoded, this would be W3sib3AiOiAiYWRkIiwgInBhdGgiOiAiL3NwZWMvcmVwbGljYXMiLCAidmFsdWUiOiAzfV0=
So a webhook response to add that label would be:
{"apiVersion":"admission.k8s.io/v1","kind":"AdmissionReview","response":{"uid":"<value from request.uid>","allowed":true,"patchType":"JSONPatch","patch":"W3sib3AiOiAiYWRkIiwgInBhdGgiOiAiL3NwZWMvcmVwbGljYXMiLCAidmFsdWUiOiAzfV0="}}
Admission webhooks can optionally return warning messages that are returned to the requesting client
in HTTP Warning headers with a warning code of 299. Warnings can be sent with allowed or rejected admission responses.
If you're implementing a webhook that returns a warning:
Don't include a "Warning:" prefix in the message
Use warning messages to describe problems the client making the API request should correct or be aware of
Limit warnings to 120 characters if possible
Caution:
Individual warning messages over 256 characters may be truncated by the API server before being returned to clients.
If more than 4096 characters of warning messages are added (from all sources), additional warning messages are ignored.
{"apiVersion":"admission.k8s.io/v1","kind":"AdmissionReview","response":{"uid":"<value from request.uid>","allowed":true,"warnings":["duplicate envvar entries specified with name MY_ENV","memory request less than 4MB specified for container mycontainer, which will not start successfully"]}}
Webhook configuration
To register admission webhooks, create MutatingWebhookConfiguration or ValidatingWebhookConfiguration API objects.
The name of a MutatingWebhookConfiguration or a ValidatingWebhookConfiguration object must be a valid
DNS subdomain name.
Note:
Names ending in .static.k8s.io are reserved for
manifest-based admission control
and cannot be used for API-based webhook configurations. This reservation is
enforced when the ManifestBasedAdmissionControlConfigfeature gate is enabled.
Each configuration can contain one or more webhooks.
If multiple webhooks are specified in a single configuration, each must be given a unique name.
This is required in order to make resulting audit logs and metrics easier to match up to active
configurations.
Each webhook defines the following things.
Matching requests: rules
Each webhook must specify a list of rules used to determine if a request to the API server should be sent to the webhook.
Each rule specifies one or more operations, apiGroups, apiVersions, and resources, and a resource scope:
operations lists one or more operations to match. Can be "CREATE", "UPDATE", "DELETE", "CONNECT",
or "*" to match all.
apiGroups lists one or more API groups to match. "" is the core API group. "*" matches all API groups.
apiVersions lists one or more API versions to match. "*" matches all API versions.
resources lists one or more resources to match.
"*" matches all resources, but not subresources.
"*/*" matches all resources and subresources.
"pods/*" matches all subresources of pods.
"*/status" matches all status subresources.
scope specifies a scope to match. Valid values are "Cluster", "Namespaced", and "*".
Subresources match the scope of their parent resource. Default is "*".
"Cluster" means that only cluster-scoped resources will match this rule (Namespace API objects are cluster-scoped).
"Namespaced" means that only namespaced resources will match this rule.
"*" means that there are no scope restrictions.
If an incoming request matches one of the specified operations, groups, versions,
resources, and scope for any of a webhook's rules, the request is sent to the webhook.
Here are other examples of rules that could be used to specify which resources should be intercepted.
Match CREATE or UPDATE requests to apps/v1 and apps/v1beta1deployments and replicasets:
Webhooks may optionally limit which requests are intercepted based on the labels of the
objects they would be sent, by specifying an objectSelector. If specified, the objectSelector
is evaluated against both the object and oldObject that would be sent to the webhook,
and is considered to match if either object matches the selector.
A null object (oldObject in the case of create, or newObject in the case of delete),
or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object)
is not considered to match.
Use the object selector only if the webhook is opt-in, because end users may skip
the admission webhook by setting the labels.
This example shows a mutating webhook that would match a CREATE of any resource (but not subresources) with the label foo: bar:
See labels concept
for more examples of label selectors.
Matching requests: namespaceSelector
Webhooks may optionally limit which requests for namespaced resources are intercepted,
based on the labels of the containing namespace, by specifying a namespaceSelector.
The namespaceSelector decides whether to run the webhook on a request for a namespaced resource
(or a Namespace object), based on whether the namespace's labels match the selector.
If the object itself is a namespace, the matching is performed on object.metadata.labels.
If the object is a cluster scoped resource other than a Namespace, namespaceSelector has no effect.
This example shows a mutating webhook that matches a CREATE of any namespaced resource inside a namespace
that does not have a "runlevel" label of "0" or "1":
This example shows a validating webhook that matches a CREATE of any namespaced resource inside
a namespace that is associated with the "environment" of "prod" or "staging":
See labels concept
for more examples of label selectors.
Matching requests: matchPolicy
API servers can make objects available via multiple API groups or versions.
For example, if a webhook only specified a rule for some API groups/versions
(like apiGroups:["apps"], apiVersions:["v1","v1beta1"]),
and a request was made to modify the resource via another API group/version (like extensions/v1beta1),
the request would not be sent to the webhook.
The matchPolicy lets a webhook define how its rules are used to match incoming requests.
Allowed values are Exact or Equivalent.
Exact means a request should be intercepted only if it exactly matches a specified rule.
Equivalent means a request should be intercepted if it modifies a resource listed in rules,
even via another API group or version.
In the example given above, the webhook that only registered for apps/v1 could use matchPolicy:
matchPolicy: Exact would mean the extensions/v1beta1 request would not be sent to the webhook
matchPolicy: Equivalent means the extensions/v1beta1 request would be sent to the webhook
(with the objects converted to a version the webhook had specified: apps/v1)
Specifying Equivalent is recommended, and ensures that webhooks continue to intercept the
resources they expect when upgrades enable new versions of the resource in the API server.
When a resource stops being served by the API server, it is no longer considered equivalent to
other versions of that resource that are still served.
For example, extensions/v1beta1 deployments were first deprecated and then removed (in Kubernetes v1.16).
Since that removal, a webhook with a apiGroups:["extensions"], apiVersions:["v1beta1"], resources:["deployments"] rule
does not intercept deployments created via apps/v1 APIs. For that reason, webhooks should prefer registering
for stable versions of resources.
This example shows a validating webhook that intercepts modifications to deployments (no matter the API group or version),
and is always sent an apps/v1Deployment object:
The matchPolicy for an admission webhooks defaults to Equivalent.
Matching requests: matchConditions
FEATURE STATE:Kubernetes v1.30 [stable](enabled by default)
You can define match conditions for webhooks if you need fine-grained request filtering. These
conditions are useful if you find that match rules, objectSelectors and namespaceSelectors still
doesn't provide the filtering you want over when to call out over HTTP. Match conditions are
CEL expressions. All match conditions must evaluate to true for the
webhook to be called.
Here is an example illustrating a few different uses for match conditions:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingWebhookConfigurationwebhooks:- name:my-webhook.example.commatchPolicy:Equivalentrules:- operations:['CREATE','UPDATE']apiGroups:['*']apiVersions:['*']resources:['*']failurePolicy:'Ignore'# Fail-open (optional)sideEffects:NoneclientConfig:service:namespace:my-namespacename:my-webhookcaBundle:'<omitted>'# You can have up to 64 matchConditions per webhookmatchConditions:- name:'exclude-leases'# Each match condition must have a unique nameexpression:'!(request.resource.group == "coordination.k8s.io" && request.resource.resource == "leases")'# Match non-lease resources.- name:'exclude-kubelet-requests'expression:'!("system:nodes" in request.userInfo.groups)'# Match requests made by non-node users.- name:'rbac'# Skip RBAC requests, which are handled by the second webhook.expression:'request.resource.group != "rbac.authorization.k8s.io"'# This example illustrates the use of the 'authorizer'. The authorization check is more expensive# than a simple expression, so in this example it is scoped to only RBAC requests by using a second# webhook. Both webhooks can be served by the same endpoint.- name:rbac.my-webhook.example.commatchPolicy:Equivalentrules:- operations:['CREATE','UPDATE']apiGroups:['rbac.authorization.k8s.io']apiVersions:['*']resources:['*']failurePolicy:'Fail'# Fail-closed (the default)sideEffects:NoneclientConfig:service:namespace:my-namespacename:my-webhookcaBundle:'<omitted>'# You can have up to 64 matchConditions per webhookmatchConditions:- name:'breakglass'# Skip requests made by users authorized to 'breakglass' on this webhook.# The 'breakglass' API verb does not need to exist outside this check.expression:'!authorizer.group("admissionregistration.k8s.io").resource("validatingwebhookconfigurations").name("my-webhook.example.com").check("breakglass").allowed()'
Note:
You can define up to 64 elements in the matchConditions field per webhook.
Match conditions have access to the following CEL variables:
object - The object from the incoming request. The value is null for DELETE requests. The object
version may be converted based on the matchPolicy.
oldObject - The existing object. The value is null for CREATE requests.
request - The request portion of the AdmissionReview, excluding object and oldObject.
authorizer - A CEL Authorizer. May be used to perform authorization checks for the principal
(authenticated user) of the request. See
Authz in the Kubernetes CEL library
documentation for more details.
authorizer.requestResource - A shortcut for an authorization check configured with the request
resource (group, resource, (subresource), namespace, name).
Once the API server has determined a request should be sent to a webhook,
it needs to know how to contact the webhook. This is specified in the clientConfig
stanza of the webhook configuration.
Webhooks can either be called via a URL or a service reference,
and can optionally include a custom CA bundle to use to verify the TLS connection.
URL
url gives the location of the webhook, in standard URL form
(scheme://host:port/path).
The host should not refer to a service running in the cluster; use
a service reference by specifying the service field instead.
The host might be resolved via external DNS in some API servers
(e.g., kube-apiserver cannot resolve in-cluster DNS as that would
be a layering violation). host may also be an IP address.
Please note that using localhost or 127.0.0.1 as a host is
risky unless you take great care to run this webhook on all hosts
which run an API server which might need to make calls to this
webhook. Such installations are likely to be non-portable or not readily
run in a new cluster.
The scheme must be "https"; the URL must begin with "https://".
Attempting to use a user or basic auth (for example user:password@) is not allowed.
Fragments (#...) and query parameters (?...) are also not allowed.
Here is an example of a mutating webhook configured to call a URL
(and expects the TLS certificate to be verified using system trust roots, so does not specify a caBundle):
The service stanza inside clientConfig is a reference to the service for this webhook.
If the webhook is running within the cluster, then you should use service instead of url.
The service namespace and name are required. The port is optional and defaults to 443.
The path is optional and defaults to "/".
Here is an example of a mutating webhook configured to call a service on port "1234"
at the subpath "/my-path", and to verify the TLS connection against the ServerName
my-service-name.my-service-namespace.svc using a custom CA bundle:
You must replace the <CA_BUNDLE> in the above example by a valid CA bundle
which is a PEM-encoded CA bundle for validating the webhook's server certificate.
Side effects
Webhooks typically operate only on the content of the AdmissionReview sent to them.
Some webhooks, however, make out-of-band changes as part of processing admission requests.
Webhooks that make out-of-band changes ("side effects") must also have a reconciliation mechanism
(like a controller) that periodically determines the actual state of the world, and adjusts
the out-of-band data modified by the admission webhook to reflect reality.
This is because a call to an admission webhook does not guarantee the admitted object will be persisted as is, or at all.
Later webhooks can modify the content of the object, a conflict could be encountered while writing to storage,
or the server could power off before persisting the object.
Additionally, webhooks with side effects must skip those side-effects when dryRun: true admission requests are handled.
A webhook must explicitly indicate that it will not have side-effects when run with dryRun,
or the dry-run request will not be sent to the webhook and the API request will fail instead.
Webhooks indicate whether they have side effects using the sideEffects field in the webhook configuration:
None: calling the webhook will have no side effects.
NoneOnDryRun: calling the webhook will possibly have side effects, but if a request with
dryRun: true is sent to the webhook, the webhook will suppress the side effects (the webhook
is dryRun-aware).
Here is an example of a validating webhook indicating it has no side effects on dryRun: true requests:
Because webhooks add to API request latency, they should evaluate as quickly as possible.
timeoutSeconds allows configuring how long the API server should wait for a webhook to respond
before treating the call as a failure.
If the timeout expires before the webhook responds, the webhook call will be ignored or
the API call will be rejected based on the failure policy.
The timeout value must be between 1 and 30 seconds.
Here is an example of a validating webhook with a custom timeout of 2 seconds:
The timeout for an admission webhook defaults to 10 seconds.
Reinvocation policy
A single ordering of mutating admissions plugins (including webhooks) does not work for all cases
(see https://issue.k8s.io/64333 as an example). A mutating webhook can add a new sub-structure
to the object (like adding a container to a pod), and other mutating plugins which have already
run may have opinions on those new structures (like setting an imagePullPolicy on all containers).
To allow mutating admission plugins to observe changes made by other plugins,
built-in mutating admission plugins are re-run if a mutating webhook modifies an object,
and mutating webhooks can specify a reinvocationPolicy to control whether they are reinvoked as well.
reinvocationPolicy may be set to Never or IfNeeded. It defaults to Never.
Never: the webhook must not be called more than once in a single admission evaluation.
IfNeeded: the webhook may be called again as part of the admission evaluation if the object
being admitted is modified by other admission plugins after the initial webhook call.
The important elements to note are:
The number of additional invocations is not guaranteed to be exactly one.
If additional invocations result in further modifications to the object, webhooks are not
guaranteed to be invoked again.
Webhooks that use this option may be reordered to minimize the number of additional invocations.
To validate an object after all mutations are guaranteed complete, use a validating admission
webhook instead (recommended for webhooks with side-effects).
Here is an example of a mutating webhook opting into being re-invoked if later admission plugins
modify the object:
Mutating webhooks must be idempotent, able to successfully process an object they have already admitted
and potentially modified. This is true for all mutating admission webhooks, since any change they can make
in an object could already exist in the user-provided object, but it is essential for webhooks that opt into reinvocation.
Failure policy
failurePolicy defines how unrecognized errors and timeout errors from the admission webhook
are handled. Allowed values are Ignore or Fail.
Ignore means that an error calling the webhook is ignored and the API request is allowed to continue.
Fail means that an error calling the webhook causes the admission to fail and the API request to be rejected.
Here is a mutating webhook configured to reject an API request if errors are encountered calling the admission webhook:
The default failurePolicy for an admission webhooks is Fail.
Monitoring admission webhooks
The API server provides ways to monitor admission webhook behaviors. These
monitoring mechanisms help cluster admins to answer questions like:
Which mutating webhook mutated the object in a API request?
What change did the mutating webhook applied to the object?
Which webhooks are frequently rejecting API requests? What's the reason for a rejection?
Mutating webhook auditing annotations
Sometimes it's useful to know which mutating webhook mutated the object in a API request, and what change did the
webhook apply.
The Kubernetes API server performs auditing on each
mutating webhook invocation. Each invocation generates an auditing annotation
capturing if a request object is mutated by the invocation, and optionally generates an annotation
capturing the applied patch from the webhook admission response. The annotations are set in the
audit event for given request on given stage of its execution, which is then pre-processed
according to a certain policy and written to a backend.
The audit level of a event determines which annotations get recorded:
At Metadata audit level or higher, an annotation with key
mutation.webhook.admission.k8s.io/round_{round idx}_index_{order idx} gets logged with JSON
payload indicating a webhook gets invoked for given request and whether it mutated the object or not.
For example, the following annotation gets recorded for a webhook being reinvoked. The webhook is
ordered the third in the mutating webhook chain, and didn't mutated the request object during the
invocation.
# the audit event recorded{"kind": "Event","apiVersion": "audit.k8s.io/v1","annotations": {"mutation.webhook.admission.k8s.io/round_1_index_2": "{\"configuration\":\"my-mutating-webhook-configuration.example.com\",\"webhook\":\"my-webhook.example.com\",\"mutated\": false}"# other annotations...}# other fields...}
# the annotation value deserialized{"configuration": "my-mutating-webhook-configuration.example.com","webhook": "my-webhook.example.com","mutated": false}
The following annotation gets recorded for a webhook being invoked in the first round. The webhook
is ordered the first in the mutating webhook chain, and mutated the request object during the
invocation.
# the audit event recorded{"kind": "Event","apiVersion": "audit.k8s.io/v1","annotations": {"mutation.webhook.admission.k8s.io/round_0_index_0": "{\"configuration\":\"my-mutating-webhook-configuration.example.com\",\"webhook\":\"my-webhook-always-mutate.example.com\",\"mutated\": true}"# other annotations...}# other fields...}
# the annotation value deserialized{"configuration": "my-mutating-webhook-configuration.example.com","webhook": "my-webhook-always-mutate.example.com","mutated": true}
At Request audit level or higher, an annotation with key
patch.webhook.admission.k8s.io/round_{round idx}_index_{order idx} gets logged with JSON payload indicating
a webhook gets invoked for given request and what patch gets applied to the request object.
For example, the following annotation gets recorded for a webhook being reinvoked. The webhook is ordered the fourth in the
mutating webhook chain, and responded with a JSON patch which got applied to the request object.
# the audit event recorded{"kind": "Event","apiVersion": "audit.k8s.io/v1","annotations": {"patch.webhook.admission.k8s.io/round_1_index_3": "{\"configuration\":\"my-other-mutating-webhook-configuration.example.com\",\"webhook\":\"my-webhook-always-mutate.example.com\",\"patch\":[{\"op\":\"add\",\"path\":\"/data/mutation-stage\",\"value\":\"yes\"}],\"patchType\":\"JSONPatch\"}"# other annotations...}# other fields...}
# the annotation value deserialized{"configuration": "my-other-mutating-webhook-configuration.example.com","webhook": "my-webhook-always-mutate.example.com","patchType": "JSONPatch","patch": [{"op": "add","path": "/data/mutation-stage","value": "yes"}]}
Admission webhook metrics
The API server exposes Prometheus metrics from the /metrics endpoint, which can be used for monitoring and
diagnosing API server status. The following metrics record status related to admission webhooks.
API server admission webhook rejection count
Sometimes it's useful to know which admission webhooks are frequently rejecting API requests, and the
reason for a rejection.
The API server exposes a Prometheus counter metric recording admission webhook rejections. The
metrics are labelled to identify the causes of webhook rejection(s):
name: the name of the webhook that rejected a request.
operation: the operation type of the request, can be one of CREATE,
UPDATE, DELETE and CONNECT.
type: the admission webhook type, can be one of admit and validating.
error_type: identifies if an error occurred during the webhook invocation
that caused the rejection. Its value can be one of:
calling_webhook_error: unrecognized errors or timeout errors from the admission webhook happened and the
webhook's Failure policy is set to Fail.
no_error: no error occurred. The webhook rejected the request with allowed: false in the admission
response. The metrics label rejection_code records the .status.code set in the admission response.
apiserver_internal_error: an API server internal error happened.
rejection_code: the HTTP status code set in the admission response when a
webhook rejected a request.
Example of the rejection count metrics:
# HELP apiserver_admission_webhook_rejection_count [ALPHA] Admission webhook rejection count, identified by name and broken out for each admission type (validating or admit) and operation. Additional labels specify an error type (calling_webhook_error or apiserver_internal_error if an error occurred; no_error otherwise) and optionally a non-zero rejection code if the webhook rejects the request with an HTTP status code (honored by the apiserver when the code is greater or equal to 400). Codes greater than 600 are truncated to 600, to keep the metrics cardinality bounded.
# TYPE apiserver_admission_webhook_rejection_count counter
apiserver_admission_webhook_rejection_count{error_type="calling_webhook_error",name="always-timeout-webhook.example.com",operation="CREATE",rejection_code="0",type="validating"} 1
apiserver_admission_webhook_rejection_count{error_type="calling_webhook_error",name="invalid-admission-response-webhook.example.com",operation="CREATE",rejection_code="0",type="validating"} 1
apiserver_admission_webhook_rejection_count{error_type="no_error",name="deny-unwanted-configmap-data.example.com",operation="CREATE",rejection_code="400",type="validating"} 13
This task guide explains some of the concepts behind ServiceAccounts. The
guide also explains how to obtain or revoke tokens that represent
ServiceAccounts, and how to (optionally) bind a ServiceAccount's validity to
the lifetime of an API object.
Before you begin
You need to have a Kubernetes cluster, and the kubectl command-line tool must
be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a
cluster, you can create one by using
minikube
or you can use one of these Kubernetes playgrounds:
To be able to follow these steps exactly, ensure you have a namespace named
examplens.
If you don't, create one by running:
kubectl create namespace examplens
User accounts versus service accounts
Kubernetes distinguishes between the concept of a user account and a service account
for a number of reasons:
User accounts are for humans. Service accounts are for application processes,
which (for Kubernetes) run in containers that are part of pods.
User accounts are intended to be global: names must be unique across all
namespaces of a cluster. No matter what namespace you look at, a particular
username that represents a user represents the same user.
In Kubernetes, service accounts are namespaced: two different namespaces can
contain ServiceAccounts that have identical names.
Typically, a cluster's user accounts might be synchronised from a corporate
database, where new user account creation requires special privileges and is
tied to complex business processes. By contrast, service account creation is
intended to be more lightweight, allowing cluster users to create service accounts
for specific tasks on demand. Separating ServiceAccount creation from the steps to
onboard human users makes it easier for workloads to follow the principle of
least privilege.
Auditing considerations for humans and service accounts may differ; the separation
makes that easier to achieve.
A configuration bundle for a complex system may include definition of various service
accounts for components of that system. Because service accounts can be created
without many constraints and have namespaced names, such configuration is
usually portable.
Bound service account tokens
ServiceAccount tokens can be bound to API objects that exist in the kube-apiserver.
This can be used to tie the validity of a token to the existence of another API object.
Supported object types are as follows:
Pod (used for projected volume mounts, see below)
Secret (can be used to allow revoking a token by deleting the Secret)
Node (can be used to auto-revoke a token when its Node is deleted; creating new node-bound tokens is GA in v1.33+)
When a token is bound to an object, the object's metadata.name and metadata.uid are
stored as extra 'private claims' in the issued JWT.
When a bound token is presented to the kube-apiserver, the service account authenticator
will extract and verify these claims.
If the referenced object or the ServiceAccount is pending deletion (for example, due to finalizers),
then for any instant that is 60 seconds (or more) after the .metadata.deletionTimestamp date,
authentication with that token would fail.
If the referenced object no longer exists (or its metadata.uid does not match),
the request will not be authenticated.
Additional metadata in Pod bound tokens
FEATURE STATE:Kubernetes v1.32 [stable](enabled by default)
When a service account token is bound to a Pod object, additional metadata is also
embedded into the token that indicates the value of the bound pod's spec.nodeName field,
and the uid of that Node, if available.
This node information is not verified by the kube-apiserver when the token is used for authentication.
It is included so integrators do not have to fetch Pod or Node API objects to check the associated Node name
and uid when inspecting a JWT.
Verifying and inspecting private claims
The TokenReview API can be used to verify and extract private claims from a token:
First, assume you have a pod named test-pod and a service account named my-sa.
Despite using kubectl create -f to create this resource, and defining it similar to
other resource types in Kubernetes, TokenReview is a special type and the kube-apiserver
does not actually persist the TokenReview object into etcd.
Hence kubectl get tokenreview is not a valid command.
Schema for service account private claims
The schema for the Kubernetes-specific claims within JWT tokens is not currently documented,
however the relevant code area can be found in
the serviceaccount package
in the Kubernetes codebase.
You can inspect a JWT using standard JWT decoding tool. Below is an example of a JWT for the
my-serviceaccount ServiceAccount, bound to a Pod object named my-pod which is scheduled
to the Node my-node, in the my-namespace namespace:
The aud and iss fields in this JWT may differ between different Kubernetes clusters depending
on your configuration.
The presence of both the pod and node claim implies that this token is bound
to a Pod object. When verifying Pod bound ServiceAccount tokens, the API server does not
verify the existence of the referenced Node object.
Services that run outside of Kubernetes and want to perform offline validation of JWTs may
use this schema, along with a compliant JWT validator configured with OpenID Discovery information
from the API server, to verify presented JWTs without requiring use of the TokenReview API.
Services that verify JWTs in this way do not verify the claims embedded in the JWT token to be
current and still valid.
This means if the token is bound to an object, and that object no longer exists, the token will still
be considered valid (until the configured token expires).
Clients that require assurance that a token's bound claims are still valid MUST use the TokenReview
API to present the token to the kube-apiserver for it to verify and expand the embedded claims, using
similar steps to the Verifying and inspecting private claims
section above, but with a supported client library.
For more information on JWTs and their structure, see the JSON Web Token RFC.
Bound service account token volume mechanism
FEATURE STATE:Kubernetes v1.22 [stable](enabled by default)
Here's an example of how that looks for a launched Pod:
...- name:kube-api-access-<random-suffix>projected:sources:- serviceAccountToken:path:token# must match the path the app expects- configMap:items:- key:ca.crtpath:ca.crtname:kube-root-ca.crt- downwardAPI:items:- fieldRef:apiVersion:v1fieldPath:metadata.namespacepath:namespace
That manifest snippet defines a projected volume that consists of three sources. In this case,
each source also represents a single path within that volume. The three sources are:
A serviceAccountToken source, that contains a token that the kubelet acquires from kube-apiserver.
The kubelet fetches time-bound tokens using the TokenRequest API. A token served for a TokenRequest expires
either when the pod is deleted or after a defined lifespan (by default, that is 1 hour).
The kubelet also refreshes that token before the token expires.
The token is bound to the specific Pod and has the kube-apiserver as its audience.
This mechanism superseded an earlier mechanism that added a volume based on a Secret,
where the Secret represented the ServiceAccount for the Pod, but did not expire.
A configMap source. The ConfigMap contains a bundle of certificate authority data. Pods can use these
certificates to make sure that they are connecting to your cluster's kube-apiserver (and not to middlebox
or an accidentally misconfigured peer).
A downwardAPI source that looks up the name of the namespace containing the Pod, and makes
that name information available to application code running inside the Pod.
Any container within the Pod that mounts this particular volume can access the above information.
Note:
There is no specific mechanism to invalidate a token issued via TokenRequest. If you no longer
trust a bound service account token for a Pod, you can delete that Pod. Deleting a Pod expires
its bound service account tokens.
Manual Secret management for ServiceAccounts
Versions of Kubernetes before v1.22 automatically created credentials for accessing
the Kubernetes API. This older mechanism was based on creating token Secrets that
could then be mounted into running Pods.
In more recent versions, including Kubernetes v1.36, API credentials
are obtained directly using the
TokenRequest API,
and are mounted into Pods using a projected volume.
The tokens obtained using this method have bounded lifetimes, and are automatically
invalidated when the Pod they are mounted into is deleted.
You can still manually create
a Secret to hold a service account token; for example, if you need a token that never expires.
Once you manually create a Secret and link it to a ServiceAccount,
the Kubernetes control plane automatically populates the token into that Secret.
Note:
Although the manual mechanism for creating a long-lived ServiceAccount token exists,
using TokenRequest
to obtain short-lived API access tokens is recommended instead.
Auto-generated legacy ServiceAccount token clean up
Before version 1.24, Kubernetes automatically generated Secret-based tokens for
ServiceAccounts. To distinguish between automatically generated tokens and
manually created ones, Kubernetes checks for a reference from the
ServiceAccount's secrets field. If the Secret is referenced in the secrets
field, it is considered an auto-generated legacy token. Otherwise, it is
considered a manually created legacy token. For example:
apiVersion:v1kind:ServiceAccountmetadata:name:build-robotnamespace:defaultsecrets:- name:build-robot-secret# usually NOT present for a manually generated token
Beginning from version 1.29, legacy ServiceAccount tokens that were generated
automatically will be marked as invalid if they remain unused for a certain
period of time (set to default at one year). Tokens that continue to be unused
for this defined period (again, by default, one year) will subsequently be
purged by the control plane.
If users use an invalidated auto-generated token, the token validator will
add an audit annotation for the key-value pair
authentication.k8s.io/legacy-token-invalidated: <secret name>/<namespace>,
increment the invalid_legacy_auto_token_uses_total metric count,
update the Secret label kubernetes.io/legacy-token-last-used with the new
date,
return an error indicating that the token has been invalidated.
When receiving this validation error, users can update the Secret to remove the
kubernetes.io/legacy-token-invalid-since label to temporarily allow use of
this token.
Here's an example of an auto-generated legacy token that has been marked with the
kubernetes.io/legacy-token-last-used and kubernetes.io/legacy-token-invalid-since
labels:
A ServiceAccount controller manages the ServiceAccounts inside namespaces, and
ensures a ServiceAccount named "default" exists in every active namespace.
Token controller
The service account token controller runs as part of kube-controller-manager.
This controller acts asynchronously. It:
watches for ServiceAccount deletion and deletes all corresponding ServiceAccount
token Secrets.
watches for ServiceAccount token Secret addition, and ensures the referenced
ServiceAccount exists, and adds a token to the Secret if needed.
watches for Secret deletion and removes a reference from the corresponding
ServiceAccount if needed.
You must pass a service account private key file to the token controller in
the kube-controller-manager using the --service-account-private-key-file
flag. The private key is used to sign generated service account tokens.
Similarly, you must pass the corresponding public key to the kube-apiserver
using the --service-account-key-file flag. The public key will be used to
verify the tokens during authentication.
FEATURE STATE:Kubernetes v1.36 [stable](enabled by default)
An alternate setup to setting --service-account-private-key-file and --service-account-key-file flags is
to configure an external JWT signer for external ServiceAccount token signing and key management.
Note that these setups are mutually exclusive and cannot be configured together.
ServiceAccount admission controller
The modification of pods is implemented via a plugin
called an Admission Controller.
It is part of the API server.
This admission controller acts synchronously to modify pods as they are created.
When this plugin is active (and it is by default on most distributions), then
it does the following when a Pod is created:
If the pod does not have a .spec.serviceAccountName set, the admission controller sets the name of the
ServiceAccount for this incoming Pod to default.
The admission controller ensures that the ServiceAccount referenced by the incoming Pod exists. If there
is no ServiceAccount with a matching name, the admission controller rejects the incoming Pod. That check
applies even for the default ServiceAccount.
Provided that neither the ServiceAccount's automountServiceAccountToken field nor the
Pod's automountServiceAccountToken field is set to false:
the admission controller mutates the incoming Pod, adding an extra
volume that contains
a token for API access.
the admission controller adds a volumeMount to each container in the Pod,
skipping any containers that already have a volume mount defined for the path
/var/run/secrets/kubernetes.io/serviceaccount.
For Linux containers, that volume is mounted at /var/run/secrets/kubernetes.io/serviceaccount;
on Windows nodes, the mount is at the equivalent path.
If the spec of the incoming Pod doesn't already contain any imagePullSecrets, then the
admission controller adds imagePullSecrets, copying them from the ServiceAccount.
Legacy ServiceAccount token tracking controller
FEATURE STATE:Kubernetes v1.28 [stable](enabled by default)
This controller generates a ConfigMap called
kube-system/kube-apiserver-legacy-service-account-token-tracking in the
kube-system namespace. The ConfigMap records the timestamp when legacy service
account tokens began to be monitored by the system.
Legacy ServiceAccount token cleaner
FEATURE STATE:Kubernetes v1.30 [stable](enabled by default)
The legacy ServiceAccount token cleaner runs as part of the
kube-controller-manager and checks every 24 hours to see if any auto-generated
legacy ServiceAccount token has not been used in a specified amount of time.
If so, the cleaner marks those tokens as invalid.
The cleaner works by first checking the ConfigMap created by the control plane
(provided that LegacyServiceAccountTokenTracking is enabled). If the current
time is a specified amount of time after the date in the ConfigMap, the
cleaner then loops through the list of Secrets in the cluster and evaluates each
Secret that has the type kubernetes.io/service-account-token.
If a Secret meets all of the following conditions, the cleaner marks it as
invalid:
The Secret is auto-generated, meaning that it is bi-directionally referenced
by a ServiceAccount.
The Secret is not currently mounted by any pods.
The Secret has not been used in a specified amount of time since it was
created or since it was last used.
The cleaner marks a Secret invalid by adding a label called
kubernetes.io/legacy-token-invalid-since to the Secret, with the current date
as the value. If an invalid Secret is not used in a specified amount of time,
the cleaner will delete it.
Note:
All the specified amount of time above defaults to one year. The cluster
administrator can configure this value through the
--legacy-service-account-token-clean-up-period command line argument for the
kube-controller-manager component.
TokenRequest API
FEATURE STATE:Kubernetes v1.22 [stable]
You use the TokenRequest
subresource of a ServiceAccount to obtain a time-bound token for that ServiceAccount.
You don't need to call this to obtain an API token for use within a container, since
the kubelet sets this up for you using a projected volume.
The Kubernetes control plane (specifically, the ServiceAccount admission controller)
adds a projected volume to Pods, and the kubelet ensures that this volume contains a token
that lets containers authenticate as the right ServiceAccount.
(This mechanism superseded an earlier mechanism that added a volume based on a Secret,
where the Secret represented the ServiceAccount for the Pod but did not expire.)
Here's an example of how that looks for a launched Pod:
That manifest snippet defines a projected volume that combines information from three sources:
A serviceAccountToken source, that contains a token that the kubelet acquires from kube-apiserver.
The kubelet fetches time-bound tokens using the TokenRequest API. A token served for a TokenRequest expires
either when the pod is deleted or after a defined lifespan (by default, that is 1 hour).
The token is bound to the specific Pod and has the kube-apiserver as its audience.
A configMap source. The ConfigMap contains a bundle of certificate authority data. Pods can use these
certificates to make sure that they are connecting to your cluster's kube-apiserver (and not to a middlebox
or an accidentally misconfigured peer).
A downwardAPI source. This downwardAPI volume makes the name of the namespace containing the Pod available
to application code running inside the Pod.
Any container within the Pod that mounts this volume can access the above information.
Create additional API tokens
Caution:
Only create long-lived API tokens if the token request mechanism
is not suitable. The token request mechanism provides time-limited tokens; because these
expire, they represent a lower risk to information security.
To create a non-expiring, persisted API token for a ServiceAccount, create a
Secret of type kubernetes.io/service-account-token with an annotation
referencing the ServiceAccount. The control plane then generates a long-lived token and
updates that Secret with that generated token data.
If you launch a new Pod into the examplens namespace, it can use the myserviceaccount
service-account-token Secret that you just created.
Caution:
Do not reference manually created Secrets in the secrets field of a
ServiceAccount. Or the manually created Secrets will be cleaned if it is not used for a long
time. Please refer to auto-generated legacy ServiceAccount token clean up.
Delete/invalidate a ServiceAccount token
Delete/invalidate a long-lived/legacy ServiceAccount token
If you know the name of the Secret that contains the token you want to remove:
kubectl delete secret name-of-secret
Otherwise, first find the Secret for the ServiceAccount.
# This assumes that you already have a namespace named 'examplens'kubectl -n examplens get serviceaccount/example-automated-thing -o yaml
Delete/invalidate a short-lived ServiceAccount token
Short lived ServiceAccount tokens automatically expire after the time-limit
specified during their creation. There is no central record of tokens issued,
so there is no way to revoke individual tokens.
If you have to revoke a short-lived token before its expiration, you
can delete and re-create the ServiceAccount it is associated to. This will
change its UID and hence invalidate all ServiceAccount tokens that were
created for it.
External ServiceAccount token signing and key management
FEATURE STATE:Kubernetes v1.36 [stable](enabled by default)
The kube-apiserver can be configured to use external signer for token signing and token verifying key management.
This feature enables kubernetes distributions to integrate with key management solutions of their choice
(for example, HSMs, cloud KMSes) for service account credential signing and verification.
To configure kube-apiserver to use external-jwt-signer set the --service-account-signing-endpoint flag
to the location of a Unix domain socket (UDS) on a filesystem, or be prefixed with an @ symbol and name
a UDS in the abstract socket namespace. At the configured UDS shall be an RPC server which implements
an ExternalJWTSigner gRPC service.
The external-jwt-signer must be healthy and be ready to serve supported service account keys for the kube-apiserver to start.
Note:
The kube-apiserver flags --service-account-key-file and --service-account-signing-key-file will continue
to be used for reading from files unless --service-account-signing-endpoint is set; they are mutually
exclusive ways of supporting JWT signing and authentication.
An external signer provides a v1.ExternalJWTSigner gRPC service that implements 3 methods:
Metadata
Metadata is meant to be called once by kube-apiserver on startup.
This enables the external signer to share metadata with kube-apiserver, like the max token lifetime that signer supports.
rpcMetadata(MetadataRequest)returns(MetadataResponse){}messageMetadataRequest{}messageMetadataResponse{// used by kube-apiserver for defaulting/validation of JWT lifetime while accounting for configuration flag values:
// 1. `--service-account-max-token-expiration`
// 2. `--service-account-extend-token-expiration`
//
// * If `--service-account-max-token-expiration` is greater than `max_token_expiration_seconds`, kube-apiserver treats that as misconfiguration and exits.
// * If `--service-account-max-token-expiration` is not explicitly set, kube-apiserver defaults to `max_token_expiration_seconds`.
// * If `--service-account-extend-token-expiration` is true, the extended expiration is `min(1 year, max_token_expiration_seconds)`.
//
// `max_token_expiration_seconds` must be at least 600s.
int64max_token_expiration_seconds=1;}
FetchKeys
FetchKeys returns the set of public keys that are trusted to sign
Kubernetes service account tokens. Kube-apiserver will call this RPC:
Every time it tries to validate a JWT from the service account issuer with an unknown key ID, and
Periodically, so it can serve reasonably-up-to-date keys from the OIDC JWKs endpoint.
rpcFetchKeys(FetchKeysRequest)returns(FetchKeysResponse){}messageFetchKeysRequest{}messageFetchKeysResponse{repeatedKeykeys=1;// The timestamp when this data was pulled from the authoritative source of
// truth for verification keys.
// kube-apiserver can export this from metrics, to enable end-to-end SLOs.
google.protobuf.Timestampdata_timestamp=2;// refresh interval for verification keys to pick changes if any.
// any value <= 0 is considered a misconfiguration.
int64refresh_hint_seconds=3;}messageKey{// A unique identifier for this key.
// Length must be <=1024.
stringkey_id=1;// The public key, PKIX-serialized.
// must be a public key supported by kube-apiserver (currently RSA 256 or ECDSA 256/384/521)
byteskey=2;// Set only for keys that are not used to sign bound tokens.
// eg: supported keys for legacy tokens.
// If set, key is used for verification but excluded from OIDC discovery docs.
// if set, external signer should not use this key to sign a JWT.
boolexclude_from_oidc_discovery=3;}
Sign
Sign takes a serialized JWT payload, and returns the serialized header and
signature. kube-apiserver then assembles the JWT from the header, payload,
and signature.
rpcSign(SignJWTRequest)returns(SignJWTResponse){}messageSignJWTRequest{// URL-safe base64 wrapped payload to be signed.
// Exactly as it appears in the second segment of the JWT
stringclaims=1;}messageSignJWTResponse{// header must contain only alg, kid, typ claims.
// typ must be “JWT”.
// kid must be non-empty, <=1024 characters, and its corresponding public key should not be excluded from OIDC discovery.
// alg must be one of the algorithms supported by kube-apiserver (currently RS256, ES256, ES384, ES512).
// header cannot have any additional data that kube-apiserver does not recognize.
// Already wrapped in URL-safe base64, exactly as it appears in the first segment of the JWT.
stringheader=1;// The signature for the JWT.
// Already wrapped in URL-safe base64, exactly as it appears in the final segment of the JWT.
stringsignature=2;}
Clean up
If you created a namespace examplens to experiment with, you can remove it:
User impersonation is a method of allowing authenticated users to act as another user,
group, or service account through HTTP headers.
A user can act as another user through impersonation headers. These let requests
manually override the user info a request authenticates as. For example, an admin
could use this feature to debug an authorization policy by temporarily
impersonating another user and seeing if a request was denied.
Impersonation requests first authenticate as the requesting user, then switch
to the impersonated user info.
A user makes an API call with their credentials and impersonation headers.
API server authenticates the user.
API server ensures the authenticated users have impersonation privileges.
Request user info is replaced with impersonation values.
Request is evaluated, authorization acts on impersonated user info.
The following HTTP headers can be used to performing an impersonation request:
Impersonate-User: The username to act as.
Impersonate-Uid: A unique identifier that represents the user being impersonated. Optional.
Requires "Impersonate-User". Kubernetes does not impose any format requirements on this string.
Impersonate-Group: A group name to act as. Can be provided multiple times to set multiple groups.
Optional. Requires "Impersonate-User".
Impersonate-Extra-( extra name ): A dynamic header used to associate extra fields with the user.
Optional. Requires "Impersonate-User". In order to be preserved consistently, ( extra name )
must be lower-case, and any characters which aren't legal in HTTP header labels
MUST be utf8 and percent-encoded.
Note:
Prior to 1.11.3 (and 1.10.7, 1.9.11), ( extra name ) could only contain characters which
were legal in HTTP header labels.
Note:
Impersonate-Uid is only available in versions 1.22.0 and higher.
An example of the impersonation headers used when impersonating a user with groups:
When using kubectl set the --as command line argument to configure the Impersonate-User
header, you can also set the --as-group flag to configure the Impersonate-Group header，
set the --as-uid flag (1.23) to configure Impersonate-Uid header, and set the
--as-user-extra flag (1.35) to configure Impersonate-Extra-( extra name ) header.
kubectl drain mynode
Error from server (Forbidden): User "clark" cannot get nodes at the cluster scope. (get nodes mynode)
To impersonate a user, user identifier (UID), group or extra fields, the impersonating user must
have the ability to perform the impersonate verb on the kind of attribute
being impersonated ("user", "uid", "group", etc.). For clusters that enable the RBAC
authorization plugin, the following ClusterRole encompasses the rules needed to
set user and group impersonation headers:
For impersonation, extra fields and impersonated UIDs are both under the "authentication.k8s.io" apiGroup.
Extra fields are evaluated as sub-resources of the resource "userextras". To
allow a user to use impersonation headers for the extra field scopes and
for UIDs, a user should be granted the following role:
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:scopes-and-uid-impersonatorrules:# Can set "Impersonate-Extra-scopes" header and the "Impersonate-Uid" header.- apiGroups:["authentication.k8s.io"]resources:["userextras/scopes","uids"]verbs:["impersonate"]
The values of impersonation headers can also be restricted by limiting the set
of resourceNames a resource can take.
apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRolemetadata:name:limited-impersonatorrules:# Can impersonate the user "jane.doe@example.com"- apiGroups:[""]resources:["users"]verbs:["impersonate"]resourceNames:["jane.doe@example.com"]# Can impersonate the groups "developers" and "admins"- apiGroups:[""]resources:["groups"]verbs:["impersonate"]resourceNames:["developers","admins"]# Can impersonate the extras field "scopes" with the values "view" and "development"- apiGroups:["authentication.k8s.io"]resources:["userextras/scopes"]verbs:["impersonate"]resourceNames:["view","development"]# Can impersonate the uid "06f6ce97-e2c5-4ab8-7ba5-7654dd08d52b"- apiGroups:["authentication.k8s.io"]resources:["uids"]verbs:["impersonate"]resourceNames:["06f6ce97-e2c5-4ab8-7ba5-7654dd08d52b"]
Note:
Impersonating a user or group allows you to perform any action as if you were that user or group;
for that reason, impersonation is not namespace scoped.
If you want to allow impersonation using Kubernetes RBAC,
this requires using a ClusterRole and a ClusterRoleBinding,
not a Role and RoleBinding.
Granting impersonation over ServiceAccounts is namespace scoped, but the impersonated ServiceAccount
could perform actions outside of namespace.
Constrained Impersonation
FEATURE STATE:Kubernetes v1.36 [beta](enabled by default)
With the impersonate verb, impersonation cannot be limited or scoped.
It either grants full impersonation or none at all. Once granted permission to
impersonate a user, you can perform any action that user can perform across all
resources and namespaces.
With constrained impersonation, an impersonator can be limited to impersonate another
user only for specific actions on specific resources, rather than being able to perform all actions
that the impersonated user can perform.
This feature is enabled by setting the ConstrainedImpersonationfeature gate.
Understanding constrained impersonation
Constrained impersonation requires two separate permissions:
Permission to impersonate a specific identity (user, UID, group, service account or node)
Permission to perform specific actions at a particular scope when impersonating (for
example, only list and watch pods in the default namespace)
This means an impersonator can be limited to impersonate another user only for specific operations.
Impersonation modes
Constrained impersonation defines three distinct modes, each with its own set of verbs:
user-info mode
Use this mode to impersonate generic users (not service accounts or nodes). This mode applies when
the Impersonate-User header value:
Does not start with system:serviceaccount:
Does not start with system:node:
Verbs:
impersonate:user-info - Permission to impersonate a specific user, group, UID, or extra field
impersonate-on:user-info:<verb> - Permission to perform <verb> when impersonating a generic user
ServiceAccount mode
Use this mode to impersonate ServiceAccounts.
Verbs:
impersonate:serviceaccount - Permission to impersonate a specific service account
impersonate-on:serviceaccount:<verb> - Permission to perform <verb> when impersonating a service account
arbitrary-node and associated-node modes
Use these modes to impersonate nodes. This mode applies when the Impersonate-User header value
starts with system:node:.
Verbs:
impersonate:arbitrary-node - Permission to impersonate any specified node
impersonate:associated-node - Permission to impersonate only the node to which the impersonator is bound
impersonate-on:arbitrary-node:<verb> - Permission to perform <verb> when impersonating any node
impersonate-on:associated-node:<verb> - Permission to perform <verb> when impersonating the associated node
Note:
The impersonate:associated-node verb only applies when the impersonator is a service account bound to the
node it's trying to impersonate. This is determined by checking if the service account's user info
contains an extra field with key authentication.kubernetes.io/node-name that matches the node
being impersonated.
Configuring constrained impersonation with RBAC
All constrained impersonation permissions use the authentication.k8s.io API group. Here's how to
configure the different modes.
Example: Impersonate a user for specific actions
This example shows how to allow a service account to impersonate a user named jane.doe@example.com,
but only to list and watch pods in the default namespace. You need both a ClusterRoleBinding
for the identity permission and a RoleBinding for the action permission
Step 1: Grant permission to impersonate the user identity
Now the my-controller service account can impersonate jane.doe@example.com to list and watch
pods in the default namespace, but cannot perform other actions like deleting pods or
accessing resources in other namespaces.
Example: Impersonate a ServiceAccount
To allow impersonating a service account named app-sa in the production namespace to create
and update deployments:
apiVersion:rbac.authorization.k8s.io/v1kind:Rolemetadata:name:impersonate-app-sanamespace:defaultrules:- apiGroups:["authentication.k8s.io"]resources:["serviceaccounts"]resourceNames:["app-sa"]# For service accounts, you must specify the namespace in the RoleBindingverbs:["impersonate:serviceaccount"]---apiVersion:rbac.authorization.k8s.io/v1kind:Rolemetadata:name:impersonate-manage-deploymentsnamespace:productionrules:- apiGroups:["apps"]resources:["deployments"]verbs:- "impersonate-on:serviceaccount:create"- "impersonate-on:serviceaccount:update"- "impersonate-on:serviceaccount:patch"---apiVersion:rbac.authorization.k8s.io/v1kind:RoleBindingmetadata:name:impersonate-app-sanamespace:defaultroleRef:apiGroup:rbac.authorization.k8s.iokind:Rolename:impersonate-app-sasubjects:- kind:ServiceAccountname:deputy-controllernamespace:default---apiVersion:rbac.authorization.k8s.io/v1kind:RoleBindingmetadata:name:impersonate-manage-deploymentsnamespace:productionroleRef:apiGroup:rbac.authorization.k8s.iokind:Rolename:impersonate-manage-deploymentssubjects:- kind:ServiceAccountname:deputy-controllernamespace:default
Example: Impersonate a node
To allow node-impersonator ServiceAccount in default namespace impersonating
a node named mynode to get and list pods:
From a client perspective, using constrained impersonation is identical to using traditional
impersonation. You use the same impersonation headers:
Impersonate-User: jane.doe@example.com
Or with kubectl:
kubectl get pods -n default --as=jane.doe@example.com
The difference is entirely in the authorization checks performed by the API server.
Working with impersonate verb
If you have existing RBAC rules using the impersonate verb, they continue
to function when the feature gate is enabled.
When an impersonation request is made, the API server first checks for
constrained impersonation permissions. If those checks fail, it falls back to checking the
impersonate permission.
Auditing
An audit event is logged for each impersonation request to help track how impersonation is used.
When a request uses constrained impersonation, the audit event includes an authenticationMetadata
object with an impersonationConstraint field that indicates which constrained impersonation verb
was used to authorize the request.
For non-watch requests that take longer than 500ms, the API server also adds an
apiserver.latency.k8s.io/impersonation annotation to the audit event
recording the time taken to process the impersonation (along with other handlers that contributed
to the overall duration).
The impersonationConstraint value indicates which mode was used (for example, impersonate:user-info,
impersonate:associated-node). The specific action (for example, list) can be determined from the
verb field in the audit event. For slow requests, the latency annotation records the time (for example,
100ms) taken to process the impersonation for the request.
Metrics
kube-apiserver exposes the following Prometheus metrics for constrained impersonation:
apiserver_impersonation_attempts_total{mode, decision}: a counter that increments on each
impersonation attempt. A mode is one of associated-node,
arbitrary-node, serviceaccount, user-info, or legacy. The decision is allowed or denied.
apiserver_impersonation_attempts_duration_seconds{mode, decision}: a histogram tracking the time taken to
resolve the impersonated user. The mode and decision labels have the same values as above. Because of
caching within the handler, this reflects the amortized latency cost of impersonation requests.
apiserver_impersonation_authorization_attempts_total{mode, decision}: a counter that increments each
time an impersonation attempt invokes the authorizer. The mode and decision labels have the same values as above.
apiserver_impersonation_authorization_attempts_duration_seconds{mode, decision}: a histogram
tracking the time taken by the authorizer for each impersonation attempt.
The mode and decision labels have the same values as above.
For metrics apiserver_impersonation_attempts_total{mode, decision} and
apiserver_impersonation_attempts_duration_seconds{mode, decision}, the mode is
the empty string when decision is denied.
3.12 - Certificates and Certificate Signing Requests
Kubernetes certificate and trust bundle APIs enable automation of
X.509 credential provisioning by providing
a programmatic interface for clients of the Kubernetes API to request and obtain
X.509 certificates from a Certificate Authority (CA).
There is also experimental (alpha) support for distributing trust bundles.
Certificate signing requests
FEATURE STATE:Kubernetes v1.19 [stable]
A CertificateSigningRequest
(CSR) resource is used to request that a certificate be signed
by a denoted signer, after which the request may be approved or denied before
finally being signed.
Request signing process
The CertificateSigningRequest resource type allows a client to ask for an X.509 certificate
be issued, based on a signing request.
The CertificateSigningRequest object includes a PEM-encoded PKCS#10 signing request in
the spec.request field. The CertificateSigningRequest denotes the signer (the
recipient that the request is being made to) using the spec.signerName field.
Note that spec.signerName is a required key after API version certificates.k8s.io/v1.
In Kubernetes v1.22 and later, clients may optionally set the spec.expirationSeconds
field to request a particular lifetime for the issued certificate. The minimum valid
value for this field is 600, i.e. ten minutes.
Once created, a CertificateSigningRequest must be approved before it can be signed.
Depending on the signer selected, a CertificateSigningRequest may be automatically approved
by a controller.
Otherwise, a CertificateSigningRequest must be manually approved either via the REST API (or client-go)
or by running kubectl certificate approve. Likewise, a CertificateSigningRequest may also be denied,
which tells the configured signer that it must not sign the request.
For certificates that have been approved, the next step is signing. The relevant signing controller
first validates that the signing conditions are met and then creates a certificate.
The signing controller then updates the CertificateSigningRequest, storing the new certificate into
the status.certificate field of the existing CertificateSigningRequest object. The
status.certificate field is either empty or contains a X.509 certificate, encoded in PEM format.
The CertificateSigningRequest status.certificate field is empty until the signer does this.
Once the status.certificate field has been populated, the request has been completed and clients can now
fetch the signed certificate PEM data from the CertificateSigningRequest resource.
The signers can instead deny certificate signing if the approval conditions are not met.
In order to reduce the number of old CertificateSigningRequest resources left in a cluster, a garbage collection
controller runs periodically. The garbage collection removes CertificateSigningRequests that have not changed
state for some duration:
Approved requests: automatically deleted after 1 hour
Denied requests: automatically deleted after 1 hour
Failed requests: automatically deleted after 1 hour
Pending requests: automatically deleted after 24 hours
All requests: automatically deleted after the issued certificate has expired
Certificate signing authorization

Signers
Signers abstractly represent the entity or entities that might sign, or have
signed, a security certificate.
Any signer that is made available for outside a particular cluster should provide information
about how the signer works, so that consumers can understand what that means for CertificateSigningRequests
and (if enabled) ClusterTrustBundles.
This includes:
Trust distribution: how trust anchors (CA certificates or certificate bundles) are distributed.
Permitted subjects: any restrictions on and behavior when a disallowed subject is requested.
Permitted x509 extensions: including IP subjectAltNames, DNS subjectAltNames,
Email subjectAltNames, URI subjectAltNames etc, and behavior when a disallowed extension is requested.
Permitted key usages / extended key usages: any restrictions on and behavior
when usages different than the signer-determined usages are specified in the CSR.
Expiration/certificate lifetime: whether it is fixed by the signer, configurable by the admin, determined by the CSR spec.expirationSeconds field, etc
and the behavior when the signer-determined expiration is different from the CSR spec.expirationSeconds field.
CA bit allowed/disallowed: and behavior if a CSR contains a request for a CA certificate when the signer does not permit it.
Commonly, the status.certificate field of a CertificateSigningRequest contains a
single PEM-encoded X.509 certificate once the CSR is approved and the certificate is issued.
Some signers store multiple certificates into the status.certificate field. In
that case, the documentation for the signer should specify the meaning of
additional certificates; for example, this might be the certificate plus
intermediates to be presented during TLS handshakes.
If you want to make the trust anchor (root certificate) available, this should be done
separately from a CertificateSigningRequest and its status.certificate field. For example,
you could use a ClusterTrustBundle.
The PKCS#10 signing request format does not have a standard mechanism to specify a
certificate expiration or lifetime. The expiration or lifetime therefore has to be set
through the spec.expirationSeconds field of the CSR object. The built-in signers
use the ClusterSigningDuration configuration option, which defaults to 1 year,
(the --cluster-signing-duration command-line flag of the kube-controller-manager)
as the default when no spec.expirationSeconds is specified. When spec.expirationSeconds
is specified, the minimum of spec.expirationSeconds and ClusterSigningDuration is
used.
Note:
The spec.expirationSeconds field was added in Kubernetes v1.22. Earlier versions of Kubernetes do not honor this field.
Kubernetes API servers prior to v1.22 will silently drop this field when the object is created.
Kubernetes signers
Kubernetes provides built-in signers that each have a well-known signerName:
kubernetes.io/kube-apiserver-client: signs certificates that will be honored as client certificates by the API server.
Never auto-approved by kube-controller-manager.
Trust distribution: signed certificates must be honored as client certificates by the API server. The CA bundle is not distributed by any other means.
Permitted subjects - no subject restrictions, but approvers and signers may choose not to approve or sign.
Certain subjects like cluster-admin level users or groups vary between distributions and installations,
but deserve additional scrutiny before approval and signing.
The CertificateSubjectRestriction admission plugin is enabled by default to restrict system:masters,
but it is often not the only cluster-admin subject in a cluster.
Permitted x509 extensions - honors subjectAltName and key usage extensions and discards other extensions.
Permitted key usages - must include ["client auth"]. Must not include key usages beyond ["digital signature", "key encipherment", "client auth"].
Expiration/certificate lifetime - for the kube-controller-manager implementation of this signer, set to the minimum
of the --cluster-signing-duration option or, if specified, the spec.expirationSeconds field of the CSR object.
CA bit allowed/disallowed - not allowed.
kubernetes.io/kube-apiserver-client-kubelet: signs client certificates that will be honored as client certificates by the
API server.
May be auto-approved by kube-controller-manager.
Trust distribution: signed certificates must be honored as client certificates by the API server. The CA bundle
is not distributed by any other means.
Permitted subjects - organizations are exactly ["system:nodes"], common name is "system:node:${NODE_NAME}".
Permitted x509 extensions - honors key usage extensions, forbids subjectAltName extensions and drops other extensions.
Expiration/certificate lifetime - for the kube-controller-manager implementation of this signer, set to the minimum
of the --cluster-signing-duration option or, if specified, the spec.expirationSeconds field of the CSR object.
CA bit allowed/disallowed - not allowed.
kubernetes.io/kubelet-serving: signs serving certificates that are honored as a valid kubelet serving certificate
by the API server, but has no other guarantees.
Never auto-approved by kube-controller-manager.
Trust distribution: signed certificates must be honored by the API server as valid to terminate connections to a kubelet.
The CA bundle is not distributed by any other means.
Permitted subjects - organizations are exactly ["system:nodes"], common name is "system:node:${NODE_NAME}".
Permitted x509 extensions - honors key usage and DNSName/IPAddress subjectAltName extensions, forbids EmailAddress and
URI subjectAltName extensions, drops other extensions. At least one DNS or IP subjectAltName must be present.
Expiration/certificate lifetime - for the kube-controller-manager implementation of this signer, set to the minimum
of the --cluster-signing-duration option or, if specified, the spec.expirationSeconds field of the CSR object.
CA bit allowed/disallowed - not allowed.
kubernetes.io/legacy-unknown: has no guarantees for trust at all. Some third-party distributions of Kubernetes
may honor client certificates signed by it. The stable CertificateSigningRequest API (version certificates.k8s.io/v1 and later)
does not allow to set the signerName as kubernetes.io/legacy-unknown.
Never auto-approved by kube-controller-manager.
Trust distribution: None. There is no standard trust or distribution for this signer in a Kubernetes cluster.
Permitted subjects - any
Permitted x509 extensions - honors subjectAltName and key usage extensions and discards other extensions.
Permitted key usages - any
Expiration/certificate lifetime - for the kube-controller-manager implementation of this signer, set to the minimum
of the --cluster-signing-duration option or, if specified, the spec.expirationSeconds field of the CSR object.
CA bit allowed/disallowed - not allowed.
kubernetes.io/kube-apiserver-serving: signs certificates that can be used to verify kube-apiserver serving
certificates. Signing and approval are handled outside kube-controller-manager.
FEATURE STATE:Kubernetes v1.33 [beta](disabled by default)
Trust distribution: signed certificates are used by the kube-apiserver for TLS
server authentication. The CA bundle is distributed using a ClusterTrustBundle object
identifiable by the kubernetes.io/kube-apiserver-serving signer name.
Permitted subjects - "Subject" itself is deprecated for TLS server authentication by RFC2818. However,
it should still follow the same rules on DNS/IP SANs
from the "Permitted x509 extensions" section below.
Permitted x509 extensions - honors subjectAltName and key usage extensions. At
least one DNS or IP subjectAltName must be present. The SAN DNS/IP of the certificates
must resolve/point to kube-apiserver's hostname/IP.
Expiration/certificate lifetime - The recommended maximum lifetime is 30 days.
CA bit allowed/disallowed - not recommended by the Kubernetes project.
Note:
The spec.expirationSeconds field was added in Kubernetes v1.22. Earlier versions of Kubernetes do not honor this field.
Kubernetes API servers prior to v1.22 will silently drop this field when the object is created.
The kube-controller-manager implements control plane signing for each of the built in
signers except for kubernetes.io/kube-apiserver-serving. Failures for all of these are only reported in kube-controller-manager logs.
Signing of certificates in the trust domain of the kubernetes.io/kube-apiserver-serving signer is in full control of
the cluster administrator(s).
Any trust outside of the above described cases is strictly
coincidental. For instance, some distributions may honor kubernetes.io/legacy-unknown as client certificates for the
kube-apiserver, but this is not a standard.
None of these usages are related to ServiceAccount token secrets .data[ca.crt] in any way. That CA bundle is only
guaranteed to verify a connection to the API server using the default service (kubernetes.default.svc).
Custom signers
You can also introduce your own custom signer, which should have a similar prefixed name but using your
own domain name. For example, if you represent an open source project that uses the domain open-fictional.example
then you might use issuer.open-fictional.example/service-mesh as a signer name.
A custom signer uses the Kubernetes API to issue a certificate. See API-based signers.
Signing
Control plane signer
The Kubernetes control plane implements each of the
Kubernetes signers,
as part of the kube-controller-manager.
Note:
Prior to Kubernetes v1.18, the kube-controller-manager would sign any CSRs that
were marked as approved.
Note:
The spec.expirationSeconds field was added in Kubernetes v1.22.
Earlier versions of Kubernetes do not honor this field.
Kubernetes API servers prior to v1.22 will silently drop this field when the object is created.
API-based signers
Users of the REST API can sign CSRs by submitting an UPDATE request to the status
subresource of the CSR to be signed.
As part of this request, the status.certificate field should be set to contain the
signed certificate. This field contains one or more PEM-encoded certificates.
All PEM blocks must have the "CERTIFICATE" label, contain no headers,
and the encoded data must be a BER-encoded ASN.1 Certificate structure
as described in section 4 of RFC5280.
Non-PEM content may appear before or after the CERTIFICATE PEM blocks and is unvalidated,
to allow for explanatory text as described in section 5.2 of RFC7468.
When encoded in JSON or YAML, this field is base-64 encoded.
A CertificateSigningRequest containing the example certificate above would look like this:
Before a signer issues a certificate based on a CertificateSigningRequest,
the signer typically checks that the issuance for that CSR has been approved.
Control plane automated approval
The kube-controller-manager ships with a built-in approver for certificates with
a signerName of kubernetes.io/kube-apiserver-client-kubelet that delegates various
permissions on CSRs for node credentials to authorization.
The kube-controller-manager POSTs SubjectAccessReview resources to the API server
in order to check authorization for certificate approval.
Approval or rejection using kubectl
A Kubernetes administrator (with appropriate permissions) can manually approve
(or deny) CertificateSigningRequests by using the kubectl certificate approve and kubectl certificate deny commands.
Users of the REST API can approve CSRs by submitting an UPDATE request to the approval
subresource of the CSR to be approved. For example, you could write an
operator that watches for a particular
kind of CSR and then sends an UPDATE to approve them.
When you make an approval or rejection request, set either the Approved or Denied
status condition based on the state you determine:
For Approved CSRs:
apiVersion:certificates.k8s.io/v1kind:CertificateSigningRequest...status:conditions:- lastUpdateTime:"2020-02-08T11:37:35Z"lastTransitionTime:"2020-02-08T11:37:35Z"message:Approved by my custom approver controllerreason:ApprovedByMyPolicy# You can set this to any stringtype:Approved
For Denied CSRs:
apiVersion:certificates.k8s.io/v1kind:CertificateSigningRequest...status:conditions:- lastUpdateTime:"2020-02-08T11:37:35Z"lastTransitionTime:"2020-02-08T11:37:35Z"message:Denied by my custom approver controllerreason:DeniedByMyPolicy# You can set this to any stringtype:Denied
It's usual to set status.conditions.reason to a machine-friendly reason
code using TitleCase; this is a convention but you can set it to anything
you like. If you want to add a note for human consumption, use the
status.conditions.message field.
PodCertificateRequests
FEATURE STATE:Kubernetes v1.35 [beta](disabled by default)
Note:
In Kubernetes 1.36, you must enable support for Pod
Certificates using the PodCertificateRequestfeature
gate and the
--runtime-config=certificates.k8s.io/v1beta1/podcertificaterequests=true
kube-apiserver flag.
PodCertificateRequests are API objects tailored to provisioning certificates to
workloads running as Pods within a cluster. The user typically does not
interact with PodCertificateRequests directly, but uses podCertificate
projected volume sources, which are a kubelet
feature that handles secure key provisioning and automatic certificate refresh.
The application inside the pod only needs to know how to read the certificates
from the filesystem.
PodCertificateRequests are similar to CertificateSigningRequests, but have a
simpler format enabled by their narrower use case.
A PodCertificateRequest has the following spec fields:
signerName: The signer to which this request is addressed.
podName and podUID: The Pod that Kubelet is requesting a certificate for.
serviceAccountName and serviceAccountUID: The ServiceAccount corresponding to the Pod.
nodeName and nodeUID: The Node corresponding to the Pod.
maxExpirationSeconds: The maximum lifetime that the workload author will
accept for this certificate. Defaults to 24 hours if not specified.
stubPKCS10Request: A minimal
PKCS#10 CSR. Signers should extract
the public key from this CSR. Typically, no other actions need to be taken
with this field from the signer side, the CSR signature is checked by the API
server. Requests from the Kubelet will only include the public key information
in the CSR.
unverifiedUserAnnotations: A map that allows the user to pass additional
information to the signer implementation. It is copied verbatim from the
userAnnotations field of the podCertificate projected volume
source. Entries are
subject to the same validation as object metadata annotations, with the
addition that all keys must be domain-prefixed. No restrictions are placed on
values, except an overall size limitation on the entire field. Other than
these basic validations, the API server does not conduct any extra
validations. The signer implementations should be very careful when consuming
this data. Signers must not inherently trust this data without first
performing the appropriate verification steps. Signers should document the
keys and values they support. Signers should deny requests that contain keys
they do not recognize.
Nodes automatically receive permissions to create PodCertificateRequests and
read PodCertificateRequests related to them (as determined by the
spec.nodeName field). The NodeRestriction admission plugin, if enabled,
ensures that nodes can only create PodCertificateRequests that correspond to a
real pod that is currently running on the node.
After creation, the spec of a PodCertificateRequest is immutable.
Unlike CSRs, PodCertificateRequests do not have an
approval phase. Once the PodCertificateRequest is created, the signer's
controller directly decides to issue or deny the request. It also has the
option to mark the request as failed, if it encountered a permanent error when
attempting to issue the request.
To take any of these actions, the signing controller needs to have the
appropriate permissions on both the PodCertificateRequest type, as well as on
the signer name:
Verbs: sign, group: certificates.k8s.io, resource: signers,
resourceName: <signerNameDomain>/<signerNamePath> or <signerNameDomain>/*
The signing controller is free to consider other information beyond what's
contained in the request, but it can rely on the information in the request to
be accurate. For example, the signing controller might load the Pod and read
annotations set on it, or perform a SubjectAccessReview on the ServiceAccount.
To issue a certificate in response to a request, the signing controller:
Adds an Issued condition to status.conditions.
Puts the issued certificate in status.certificateChain
Puts the NotBefore and NotAfter fields of the certificate in the
status.notBefore and status.notAfter fields — these fields are
denormalized into the Kubernetes API in order to aid debugging
Suggests a time to begin attempting to refresh the certificate using
status.beginRefreshAt.
To deny a request, the signing controller adds a "Denied" condition to
status.conditions[].
To mark a request failed, the signing controller adds a "Failed" condition to
status.conditions[].
All of these conditions are mutually-exclusive, and must have status "True". No
other condition types are permitted on PodCertificateRequests. In addition,
once any of these conditions are set, the status field becomes immutable.
Like all conditions, the status.conditions[].reason field is meant to contain
a machine-readable code describing the condition in TitleCase. The
status.conditions[].message field is meant for a free-form explanation for
human consumption.
To ensure that terminal PodCertificateRequests do not build up in the cluster, a
kube-controller-manager controller deletes all PodCertificateRequests older
than 15 minutes. All certificate issuance flows are expected to complete within
this 15-minute limit.
Cluster trust bundles
FEATURE STATE:Kubernetes v1.33 [beta](disabled by default)
Note:
In Kubernetes 1.36, you must enable the ClusterTrustBundlefeature gateand the certificates.k8s.io/v1alpha1API group in order to use
this API.
A ClusterTrustBundles is a cluster-scoped object for distributing X.509 trust
anchors (root certificates) to workloads within the cluster. They're designed
to work well with the signer concept from CertificateSigningRequests.
All ClusterTrustBundle objects have strong validation on the contents of their
trustBundle field. That field must contain one or more X.509 certificates,
DER-serialized, each wrapped in a PEM CERTIFICATE block. The certificates
must parse as valid X.509 certificates.
Esoteric PEM features like inter-block data and intra-block headers are either
rejected during object validation, or can be ignored by consumers of the object.
Additionally, consumers are allowed to reorder the certificates in
the bundle with their own arbitrary but stable ordering.
ClusterTrustBundle objects should be considered world-readable within the
cluster. If your cluster uses RBAC
authorization, all ServiceAccounts have a default grant that allows them to
get, list, and watch all ClusterTrustBundle objects.
If you use your own authorization mechanism and you have enabled
ClusterTrustBundles in your cluster, you should set up an equivalent rule to
make these objects public within the cluster, so that they work as intended.
If you do not have permission to list cluster trust bundles by default in your
cluster, you can impersonate a service account you have access to in order to
see available ClusterTrustBundles:
kubectl get clustertrustbundles --as='system:serviceaccount:mynamespace:default'
Signer-linked ClusterTrustBundles
Signer-linked ClusterTrustBundles are associated with a signer name, like this:
apiVersion:certificates.k8s.io/v1alpha1kind:ClusterTrustBundlemetadata:name:example.com:mysigner:foospec:signerName:example.com/mysignertrustBundle:"<... PEM data ...>"
These ClusterTrustBundles are intended to be maintained by a signer-specific
controller in the cluster, so they have several security features:
To create or update a signer-linked ClusterTrustBundle, you must be permitted
to attest on the signer (custom authorization verb attest,
API group certificates.k8s.io; resource path signers). You can configure
authorization for the specific resource name
<signerNameDomain>/<signerNamePath> or match a pattern such as
<signerNameDomain>/*.
Signer-linked ClusterTrustBundles must be named with a prefix derived from
their spec.signerName field. Slashes (/) are replaced with colons (:),
and a final colon is appended. This is followed by an arbitrary name. For
example, the signer example.com/mysigner can be linked to a
ClusterTrustBundle example.com:mysigner:<arbitrary-name>.
Signer-linked ClusterTrustBundles will typically be consumed in workloads
by a combination of a
field selector on the signer name, and a separate
label selector.
Signer-unlinked ClusterTrustBundles
Signer-unlinked ClusterTrustBundles have an empty spec.signerName field, like this:
apiVersion:certificates.k8s.io/v1alpha1kind:ClusterTrustBundlemetadata:name:foospec:# no signerName specified, so the field is blanktrustBundle:"<... PEM data ...>"
They are primarily intended for cluster configuration use cases.
Each signer-unlinked ClusterTrustBundle is an independent object, in contrast to the
customary grouping behavior of signer-linked ClusterTrustBundles.
Signer-unlinked ClusterTrustBundles have no attest verb requirement.
Instead, you control access to them directly using the usual mechanisms,
such as role-based access control.
To distinguish them from signer-linked ClusterTrustBundles, the names of
signer-unlinked ClusterTrustBundles must not contain a colon (:).
Accessing ClusterTrustBundles from pods
FEATURE STATE:Kubernetes v1.33 [beta](disabled by default)
The contents of ClusterTrustBundles can be injected into the container filesystem, similar to ConfigMaps and Secrets.
See the clusterTrustBundle projected volume source for more details.
3.13 - Mapping PodSecurityPolicies to Pod Security Standards
The tables below enumerate the configuration parameters on
PodSecurityPolicy objects, whether the field mutates
and/or validates pods, and how the configuration values map to the
Pod Security Standards.
For each applicable parameter, the allowed values for the
Baseline and
Restricted profiles are listed.
Anything outside the allowed values for those profiles would fall under the
Privileged profile. "No opinion"
means all values are allowed under all Pod Security Standards.
Baseline: "runtime/default,"(Trailing comma to allow unset)
Restricted: "runtime/default"(No trailing comma)
localhost/* values are also permitted for both Baseline & Restricted.
3.14 - Kubelet authentication/authorization
Overview
A kubelet's HTTPS endpoint exposes APIs which give access to data of varying sensitivity,
and allow you to perform operations with varying levels of power on the node and within containers.
This document describes how to authenticate and authorize access to the kubelet's HTTPS endpoint.
Kubelet authentication
By default, requests to the kubelet's HTTPS endpoint that are not rejected by other configured
authentication methods are treated as anonymous requests, and given a username of system:anonymous
and a group of system:unauthenticated.
To disable anonymous access and send 401 Unauthorized responses to unauthenticated requests:
start the kubelet with the --anonymous-auth=false flag
To enable X509 client certificate authentication to the kubelet's HTTPS endpoint:
start the kubelet with the --client-ca-file flag, providing a CA bundle to verify client certificates with
start the apiserver with --kubelet-client-certificate and --kubelet-client-key flags
To enable API bearer tokens (including service account tokens) to be used to authenticate to the kubelet's HTTPS endpoint:
ensure the authentication.k8s.io/v1 API group is enabled in the API server
start the kubelet with the --authentication-token-webhook and --kubeconfig flags
the kubelet calls the TokenReview API on the configured API server to determine user information from bearer tokens
Kubelet authorization
Any request that is successfully authenticated (including an anonymous request) is then authorized. The default authorization mode is AlwaysAllow, which allows all requests.
There are many possible reasons to subdivide access to the kubelet API:
anonymous auth is enabled, but anonymous users' ability to call the kubelet API should be limited
bearer token auth is enabled, but arbitrary API users' (like service accounts) ability to call the kubelet API should be limited
client certificate auth is enabled, but only some of the client certificates signed by the configured CA should be allowed to use the kubelet API
To subdivide access to the kubelet API, delegate authorization to the API server:
ensure the authorization.k8s.io/v1 API group is enabled in the API server
start the kubelet with the --authorization-mode=Webhook and the --kubeconfig flags
the kubelet calls the SubjectAccessReview API on the configured API server to determine whether each request is authorized
The kubelet authorizes API requests using the same request attributes approach as the apiserver.
The verb is determined from the incoming request's HTTP verb:
HTTP verb
request verb
POST
create
GET, HEAD
get
PUT
update
PATCH
patch
DELETE
delete
The resource and subresource is determined from the incoming request's path:
Kubelet API
resource
subresource
/stats/*
nodes
stats
/metrics/*
nodes
metrics
/logs/*
nodes
log
/spec/*
nodes
spec
/checkpoint/*
nodes
checkpoint
all others
nodes
proxy
Warning:
nodes/proxy permission grants access to all other kubelet APIs.
This includes APIs that can be used to execute commands in any container running on the node.
Some of these endpoints support Websocket protocols via HTTP GET requests, which are authorized with the get verb.
This means that get permission on nodes/proxy is not a read-only permission,
and authorizes executing commands in any container running on the node.
The namespace and API group attributes are always an empty string, and
the resource name is always the name of the kubelet's Node API object.
When running in this mode, ensure the user identified by the --kubelet-client-certificate and --kubelet-client-key
flags passed to the apiserver is authorized for the following attributes:
verb=*, resource=nodes, subresource=proxy
verb=*, resource=nodes, subresource=stats
verb=*, resource=nodes, subresource=log
verb=*, resource=nodes, subresource=spec
verb=*, resource=nodes, subresource=metrics
Fine-grained authorization
FEATURE STATE:Kubernetes v1.36 [stable](enabled by default)
Kubelet performs a fine-grained check before falling back to the proxy
subresource for the /pods, /runningPods, /configz and /healthz
endpoints. The resource and subresource are determined from the incoming
request's path:
Kubelet API
resource
subresource
/stats/*
nodes
stats
/metrics/*
nodes
metrics
/logs/*
nodes
log
/pods
nodes
pods, proxy
/runningPods/
nodes
pods, proxy
/healthz
nodes
healthz, proxy
/configz
nodes
configz, proxy
all others
nodes
proxy
When the feature-gate KubeletFineGrainedAuthz is enabled, ensure the user
identified by the --kubelet-client-certificate and --kubelet-client-key
flags passed to the API server is authorized for the following attributes:
verb=*, resource=nodes, subresource=proxy
verb=*, resource=nodes, subresource=stats
verb=*, resource=nodes, subresource=log
verb=*, resource=nodes, subresource=metrics
verb=*, resource=nodes, subresource=configz
verb=*, resource=nodes, subresource=healthz
verb=*, resource=nodes, subresource=pods
If RBAC authorization is used,
enabling this gate also ensure that the builtin system:kubelet-api-admin ClusterRole
is updated with permissions to access all the above mentioned subresources.
3.15 - TLS bootstrapping
In a Kubernetes cluster, the components on the worker nodes - kubelet and kube-proxy - need
to communicate with Kubernetes control plane components, specifically kube-apiserver.
In order to ensure that communication is kept private, not interfered with, and ensure that
each component of the cluster is talking to another trusted component, we strongly
recommend using client TLS certificates on nodes.
The normal process of bootstrapping these components, especially worker nodes that need certificates
so they can communicate safely with kube-apiserver, can be a challenging process as it is often outside
of the scope of Kubernetes and requires significant additional work.
This in turn, can make it challenging to initialize or scale a cluster.
In order to simplify the process, beginning in version 1.4, Kubernetes introduced a certificate request
and signing API. The proposal can be found here.
This document describes the process of node initialization, how to set up TLS client certificate bootstrapping for
kubelets, and how it works.
Initialization process
When a worker node starts up, the kubelet does the following:
Look for its kubeconfig file
Retrieve the URL of the API server and credentials, normally a TLS key and signed certificate from the kubeconfig file
Attempt to communicate with the API server using the credentials.
Assuming that the kube-apiserver successfully validates the kubelet's credentials,
it will treat the kubelet as a valid node, and begin to assign pods to it.
Note that the above process depends upon:
Existence of a key and certificate on the local host in the kubeconfig
The certificate having been signed by a Certificate Authority (CA) trusted by the kube-apiserver
All of the following are responsibilities of whoever sets up and manages the cluster:
Creating the CA key and certificate
Distributing the CA certificate to the control plane nodes, where kube-apiserver is running
Creating a key and certificate for each kubelet; strongly recommended to have a unique one, with a unique CN, for each kubelet
Signing the kubelet certificate using the CA key
Distributing the kubelet key and signed certificate to the specific node on which the kubelet is running
The TLS Bootstrapping described in this document is intended to simplify, and partially or even
completely automate, steps 3 onwards, as these are the most common when initializing or scaling
a cluster.
Bootstrap initialization
In the bootstrap initialization process, the following occurs:
kubelet begins
kubelet sees that it does not have a kubeconfig file
kubelet searches for and finds a bootstrap-kubeconfig file
kubelet reads its bootstrap file, retrieving the URL of the API server and a limited usage "token"
kubelet connects to the API server, authenticates using the token
kubelet now has limited credentials to create and retrieve a certificate signing request (CSR)
kubelet creates a CSR for itself with the signerName set to kubernetes.io/kube-apiserver-client-kubelet
CSR is approved in one of two ways:
If configured, kube-controller-manager automatically approves the CSR
If configured, an outside process, possibly a person, approves the CSR using the Kubernetes API or via kubectl
Certificate is created for the kubelet
Certificate is issued to the kubelet
kubelet retrieves the certificate
kubelet creates a proper kubeconfig with the key and signed certificate
kubelet begins normal operation
Optional: if configured, kubelet automatically requests renewal of the certificate when it is close to expiry
The renewed certificate is approved and issued, either automatically or manually, depending on configuration.
The rest of this document describes the necessary steps to configure TLS Bootstrapping, and its limitations.
Configuration
To configure for TLS bootstrapping and optional automatic approval, you must configure options on the following components:
kube-apiserver
kube-controller-manager
kubelet
in-cluster resources: ClusterRoleBinding and potentially ClusterRole
In addition, you need your Kubernetes Certificate Authority (CA).
Certificate Authority
As without bootstrapping, you will need a Certificate Authority (CA) key and certificate.
As without bootstrapping, these will be used to sign the kubelet certificate. As before,
it is your responsibility to distribute them to control plane nodes.
For the purposes of this document, we will assume these have been distributed to control
plane nodes at /var/lib/kubernetes/ca.pem (certificate) and /var/lib/kubernetes/ca-key.pem (key).
We will refer to these as "Kubernetes CA certificate and key".
All Kubernetes components that use these certificates - kubelet, kube-apiserver,
kube-controller-manager - assume the key and certificate to be PEM-encoded.
kube-apiserver configuration
The kube-apiserver has several requirements to enable TLS bootstrapping:
Recognizing CA that signs the client certificate
Authenticating the bootstrapping kubelet to the system:bootstrappers group
Authorize the bootstrapping kubelet to create a certificate signing request (CSR)
Recognizing client certificates
This is normal for all client certificate authentication.
If not already set, add the --client-ca-file=FILENAME flag to the kube-apiserver command to enable
client certificate authentication, referencing a certificate authority bundle
containing the signing certificate, for example
--client-ca-file=/var/lib/kubernetes/ca.pem.
Initial bootstrap authentication
In order for the bootstrapping kubelet to connect to kube-apiserver and request a certificate,
it must first authenticate to the server. You can use any
authenticator that can authenticate the kubelet.
While any authentication strategy can be used for the kubelet's initial
bootstrap credentials, the following two authenticators are recommended for ease
of provisioning.
Using bootstrap tokens is a simpler and more easily managed method to authenticate kubelets,
and does not require any additional flags when starting kube-apiserver.
Whichever method you choose, the requirement is that the kubelet be able to authenticate as a user with the rights to:
create and retrieve CSRs
be automatically approved to request node client certificates, if automatic approval is enabled.
A kubelet authenticating using bootstrap tokens is authenticated as a user in the group
system:bootstrappers, which is the standard method to use.
As this feature matures, you
should ensure tokens are bound to a Role Based Access Control (RBAC) policy
which limits requests (using the bootstrap token) strictly to client
requests related to certificate provisioning. With RBAC in place, scoping the
tokens to a group allows for great flexibility. For example, you could disable a
particular bootstrap group's access when you are done provisioning the nodes.
Bootstrap tokens
Bootstrap tokens are described in detail here.
These are tokens that are stored as secrets in the Kubernetes cluster, and then issued to the individual kubelet.
You can use a single token for an entire cluster, or issue one per worker node.
The process is two-fold:
Create a Kubernetes secret with the token ID, secret and scope(s).
Issue the token to the kubelet
From the kubelet's perspective, one token is like another and has no special meaning.
From the kube-apiserver's perspective, however, the bootstrap token is special.
Due to its type, namespace and name, kube-apiserver recognizes it as a special token,
and grants anyone authenticating with that token special bootstrap rights, notably treating
them as a member of the system:bootstrappers group. This fulfills a basic requirement
for TLS bootstrapping.
The details for creating the secret are available here.
If you want to use bootstrap tokens, you must enable it on kube-apiserver with the flag:
--enable-bootstrap-token-auth=true
Token authentication file
kube-apiserver has the ability to accept tokens as authentication.
These tokens are arbitrary but should represent at least 128 bits of entropy derived
from a secure random number generator (such as /dev/urandom on most modern Linux
systems). There are multiple ways you can generate a token. For example:
head -c 16 /dev/urandom | od -An -t x | tr -d ' '
This will generate tokens that look like 02b50b05283e98dd0fd71db496ef01e8.
The token file should look like the following example, where the first three
values can be anything and the quoted group name should be as depicted:
Add the --token-auth-file=FILENAME flag to the kube-apiserver command (in your
systemd unit file perhaps) to enable the token file. See docs
here for
further details.
Authorize kubelet to create CSR
Now that the bootstrapping node is authenticated as part of the
system:bootstrappers group, it needs to be authorized to create a
certificate signing request (CSR) as well as retrieve it when done.
Fortunately, Kubernetes ships with a ClusterRole with precisely these (and
only these) permissions, system:node-bootstrapper.
To do this, you only need to create a ClusterRoleBinding that binds the system:bootstrappers
group to the cluster role system:node-bootstrapper.
# enable bootstrapping nodes to create CSRapiVersion:rbac.authorization.k8s.io/v1kind:ClusterRoleBindingmetadata:name:create-csrs-for-bootstrappingsubjects:- kind:Groupname:system:bootstrappersapiGroup:rbac.authorization.k8s.ioroleRef:kind:ClusterRolename:system:node-bootstrapperapiGroup:rbac.authorization.k8s.io
kube-controller-manager configuration
While the apiserver receives the requests for certificates from the kubelet and authenticates those requests,
the controller-manager is responsible for issuing actual signed certificates.
The controller-manager performs this function via a certificate-issuing control loop.
This takes the form of a
cfssl local signer using
assets on disk. Currently, all certificates issued have one year validity and a
default set of key usages.
In order for the controller-manager to sign certificates, it needs the following:
access to the "Kubernetes CA key and certificate" that you created and distributed
enabling CSR signing
Access to key and certificate
As described earlier, you need to create a Kubernetes CA key and certificate, and distribute it to the control plane nodes.
These will be used by the controller-manager to sign the kubelet certificates.
Since these signed certificates will, in turn, be used by the kubelet to authenticate as a regular kubelet
to kube-apiserver, it is important that the CA provided to the controller-manager at this stage also be
trusted by kube-apiserver for authentication. This is provided to kube-apiserver with the flag --client-ca-file=FILENAME
(for example, --client-ca-file=/var/lib/kubernetes/ca.pem), as described in the kube-apiserver configuration section.
To provide the Kubernetes CA key and certificate to kube-controller-manager, use the following flags:
The validity duration of signed certificates can be configured with flag:
--cluster-signing-duration
Approval
In order to approve CSRs, you need to tell the controller-manager that it is acceptable to approve them. This is done by granting
RBAC permissions to the correct group.
There are two distinct sets of permissions:
nodeclient: If a node is creating a new certificate for a node, then it does not have a certificate yet.
It is authenticating using one of the tokens listed above, and thus is part of the group system:bootstrappers.
selfnodeclient: If a node is renewing its certificate, then it already has a certificate (by definition),
which it uses continuously to authenticate as part of the group system:nodes.
To enable the kubelet to request and receive a new certificate, create a ClusterRoleBinding that binds
the group in which the bootstrapping node is a member system:bootstrappers to the ClusterRole that
grants it permission, system:certificates.k8s.io:certificatesigningrequests:nodeclient:
# Approve all CSRs for the group "system:bootstrappers"apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRoleBindingmetadata:name:auto-approve-csrs-for-groupsubjects:- kind:Groupname:system:bootstrappersapiGroup:rbac.authorization.k8s.ioroleRef:kind:ClusterRolename:system:certificates.k8s.io:certificatesigningrequests:nodeclientapiGroup:rbac.authorization.k8s.io
To enable the kubelet to renew its own client certificate, create a ClusterRoleBinding that binds
the group in which the fully functioning node is a member system:nodes to the ClusterRole that
grants it permission, system:certificates.k8s.io:certificatesigningrequests:selfnodeclient:
# Approve renewal CSRs for the group "system:nodes"apiVersion:rbac.authorization.k8s.io/v1kind:ClusterRoleBindingmetadata:name:auto-approve-renewals-for-nodessubjects:- kind:Groupname:system:nodesapiGroup:rbac.authorization.k8s.ioroleRef:kind:ClusterRolename:system:certificates.k8s.io:certificatesigningrequests:selfnodeclientapiGroup:rbac.authorization.k8s.io
The csrapproving controller that ships as part of
kube-controller-manager and is enabled
by default. The controller uses the
SubjectAccessReview API to
determine if a given user is authorized to request a CSR, then approves based on
the authorization outcome. To prevent conflicts with other approvers, the
built-in approver doesn't explicitly deny CSRs. It only ignores unauthorized
requests. The controller also prunes expired certificates as part of garbage
collection.
kubelet configuration
Finally, with the control plane nodes properly set up and all of the necessary
authentication and authorization in place, we can configure the kubelet.
The kubelet requires the following configuration to bootstrap:
A path to store the key and certificate it generates (optional, can use default)
A path to a kubeconfig file that does not yet exist; it will place the bootstrapped config file here
A path to a bootstrap kubeconfig file to provide the URL for the server and bootstrap credentials, e.g. a bootstrap token
Optional: instructions to rotate certificates
The bootstrap kubeconfig should be in a path available to the kubelet, for example /var/lib/kubelet/bootstrap-kubeconfig.
Its format is identical to a normal kubeconfig file. A sample file might look as follows:
certificate-authority: path to a CA file, used to validate the server certificate presented by kube-apiserver
server: URL to kube-apiserver
token: the token to use
The format of the token does not matter, as long as it matches what kube-apiserver expects. In the above example, we used a bootstrap token.
As stated earlier, any valid authentication method can be used, not only tokens.
Because the bootstrap kubeconfigis a standard kubeconfig, you can use kubectl to generate it. To create the above example file:
When starting the kubelet, if the file specified via --kubeconfig does not
exist, the bootstrap kubeconfig specified via --bootstrap-kubeconfig is used
to request a client certificate from the API server. On approval of the
certificate request and receipt back by the kubelet, a kubeconfig file
referencing the generated key and obtained certificate is written to the path
specified by --kubeconfig. The certificate and key file will be placed in the
directory specified by --cert-dir.
Client and serving certificates
All of the above relate to kubelet client certificates, specifically, the certificates a kubelet
uses to authenticate to kube-apiserver.
A kubelet also can use serving certificates. The kubelet itself exposes an https endpoint for certain features.
To secure these, the kubelet can do one of:
use provided key and certificate, via the --tls-private-key-file and --tls-cert-file flags
create self-signed key and certificate, if a key and certificate are not provided
request serving certificates from the cluster server, via the CSR API
The client certificate provided by TLS bootstrapping is signed, by default, for client auth only, and thus cannot
be used as serving certificates, or server auth.
However, you can enable its server certificate, at least partially, via certificate rotation.
Certificate rotation
Kubernetes v1.8 and higher kubelet implements features for enabling
rotation of its client and/or serving certificates. Note, rotation of serving
certificate is a beta feature and requires the RotateKubeletServerCertificate
feature flag on the kubelet (enabled by default).
You can configure the kubelet to rotate its client certificates by creating new CSRs
as its existing credentials expire. To enable this feature, use the rotateCertificates
field of kubelet configuration file
or pass the following command line argument to the kubelet (deprecated):
--rotate-certificates
Enabling RotateKubeletServerCertificate causes the kubelet both to request a serving
certificate after bootstrapping its client credentials and to rotate that
certificate. To enable this behavior, use the field serverTLSBootstrap of
the kubelet configuration file
or pass the following command line argument to the kubelet (deprecated):
--rotate-server-certificates
Note:
The CSR approving controllers implemented in core Kubernetes do not
approve node serving certificates for
security reasons. To use
RotateKubeletServerCertificate operators need to run a custom approving
controller, or manually approve the serving certificate requests.
A deployment-specific approval process for kubelet serving certificates should typically only approve CSRs which:
are requested by nodes (ensure the spec.username field is of the form
system:node:<nodeName> and spec.groups contains system:nodes)
request usages for a serving certificate (ensure spec.usages contains server auth,
optionally contains digital signature and key encipherment, and contains no other usages)
only have IP and DNS subjectAltNames that belong to the requesting node,
and have no URI and Email subjectAltNames (parse the x509 Certificate Signing Request
in spec.request to verify subjectAltNames)
Other authenticating components
All of TLS bootstrapping described in this document relates to the kubelet. However,
other components may need to communicate directly with kube-apiserver. Notable is kube-proxy, which
is part of the Kubernetes node components and runs on every node, but may also include other components such as monitoring or networking.
Like the kubelet, these other components also require a method of authenticating to kube-apiserver.
You have several options for generating these credentials:
The old way: Create and distribute certificates the same way you did for kubelet before TLS bootstrapping
DaemonSet: Since the kubelet itself is loaded on each node, and is sufficient to start base services,
you can run kube-proxy and other node-specific services not as a standalone process, but rather as a
daemonset in the kube-system namespace. Since it will be in-cluster, you can give it a proper service
account with appropriate permissions to perform its activities. This may be the simplest way to configure
such services.
kubectl approval
CSRs can be approved outside of the approval flows built into the controller
manager.
The signing controller does not immediately sign all certificate requests.
Instead, it waits until they have been flagged with an "Approved" status by an
appropriately-privileged user. This flow is intended to allow for automated
approval handled by an external approval controller or the approval controller
implemented in the core controller-manager. However cluster administrators can
also manually approve certificate requests using kubectl. An administrator can
list CSRs with kubectl get csr and describe one in detail with
kubectl describe csr <name>. An administrator can approve or deny a CSR with
kubectl certificate approve <name> and kubectl certificate deny <name>.
3.16 - Manifest-Based Admission Control
FEATURE STATE:Kubernetes v1.36 [alpha](disabled by default)
This page provides an overview of manifest-based admission control configuration.
Manifest-based admission control lets you load
admission webhooks
and CEL-based admission policies from static files on disk, rather than from the
Kubernetes API. These policies are active from API server startup, operate
independently of etcd, and can
protect API-based admission resources from modification.
To use the feature, enable the ManifestBasedAdmissionControlConfigfeature gate and
configure the staticManifestsDir field in the
AdmissionConfiguration
file passed to the kube-apiserver via --admission-control-config-file.
Why use manifest-based admission control?
Admission policies and webhooks registered through the Kubernetes API (such as
ValidatingAdmissionPolicy, MutatingAdmissionPolicy,
ValidatingWebhookConfiguration, and MutatingWebhookConfiguration) have several
inherent limitations:
Bootstrap gap: REST-based policy enforcement requires the API objects to be
created and loaded by the dynamic admission controller. Until that happens,
policies are not enforced.
Self-protection gap: Admission configuration resources (such as
ValidatingWebhookConfiguration) are not themselves subject to webhook
admission, to prevent circular dependencies. A user with sufficient privileges
can delete or modify critical admission policies.
etcd dependency: REST-based admission configurations depend on etcd
availability. If etcd is unavailable or corrupted, admission policies may not
load correctly.
Manifest-based admission control addresses these limitations by loading
configurations from files on disk. These configurations are:
Active as soon as the API server is ready to serve requests
Not visible or changeable through the Kubernetes API
Independent of etcd availability
Able to intercept operations on API-based admission resources themselves
Supported resource types
You can include the following resource types in manifest files. Only the
admissionregistration.k8s.io/v1 API version is supported.
Supported resource types for manifest-based admission control
You can also use v1.List to wrap multiple resources of the same plugin type
in a single document.
Each admission plugin's staticManifestsDir must only contain resource types
allowed for that plugin. For example, a directory configured for the
ValidatingAdmissionPolicy plugin can only contain ValidatingAdmissionPolicy
and ValidatingAdmissionPolicyBinding resources.
Configuring manifest-based admission control
To enable manifest-based admission control, you need:
The ManifestBasedAdmissionControlConfig feature gate enabled on the
kube-apiserver.
An AdmissionConfiguration file with staticManifestsDir fields pointing
to directories containing your manifest files.
The manifest files themselves on disk, accessible to the kube-apiserver
process.
AdmissionConfiguration
Add staticManifestsDir to the plugin configuration for each admission plugin
that should load manifests from disk. Each plugin requires its own directory.
# This is an example AdmissionConfiguration that configures all four admission# plugins to load manifest-based admission control from static files on disk.apiVersion:apiserver.config.k8s.io/v1kind:AdmissionConfigurationplugins:- name:ValidatingAdmissionWebhookconfiguration:apiVersion:apiserver.config.k8s.io/v1kind:WebhookAdmissionConfigurationkubeConfigFile:"<path-to-kubeconfig>"staticManifestsDir:"/etc/kubernetes/admission/validating-webhooks/"- name:MutatingAdmissionWebhookconfiguration:apiVersion:apiserver.config.k8s.io/v1kind:WebhookAdmissionConfigurationkubeConfigFile:"<path-to-kubeconfig>"staticManifestsDir:"/etc/kubernetes/admission/mutating-webhooks/"- name:ValidatingAdmissionPolicyconfiguration:apiVersion:apiserver.config.k8s.io/v1kind:ValidatingAdmissionPolicyConfigurationstaticManifestsDir:"/etc/kubernetes/admission/validating-policies/"- name:MutatingAdmissionPolicyconfiguration:apiVersion:apiserver.config.k8s.io/v1kind:MutatingAdmissionPolicyConfigurationstaticManifestsDir:"/etc/kubernetes/admission/mutating-policies/"
The staticManifestsDir field accepts an absolute path to a directory. All
direct-children files with .yaml, .yml, or .json extensions in the
directory are loaded. Subdirectories and files with other extensions are ignored.
Glob patterns and relative paths are not supported.
Pass this file to the kube-apiserver with the --admission-control-config-file
flag.
Configuration types
Each admission plugin uses a specific configuration kind:
Configuration types for each admission plugin
Plugin
apiVersion
kind
ValidatingAdmissionWebhook
apiserver.config.k8s.io/v1
WebhookAdmissionConfiguration
MutatingAdmissionWebhook
apiserver.config.k8s.io/v1
WebhookAdmissionConfiguration
ValidatingAdmissionPolicy
apiserver.config.k8s.io/v1
ValidatingAdmissionPolicyConfiguration
MutatingAdmissionPolicy
apiserver.config.k8s.io/v1
MutatingAdmissionPolicyConfiguration
Writing manifest files
Manifest files contain standard Kubernetes resource definitions. You can include
multiple resources in a single file using YAML document separators (---).
Naming convention
All objects in manifest files must have names ending with the .static.k8s.io
suffix. For example: deny-privileged.static.k8s.io.
When the ManifestBasedAdmissionControlConfig feature gate is enabled, creation
of API-based admission objects with names ending in .static.k8s.io is blocked.
When the feature gate is disabled, a warning is returned instead.
Note:
If two manifest files define objects of the same type with the same name, the
API server fails to start, displaying a descriptive error.
Restrictions
Manifest-based admission configurations exist in isolation and cannot
reference API resources. The following restrictions apply:
Webhooks: Must use clientConfig.url. The clientConfig.service field is
not allowed because the service network may not be available at API server
startup.
Policies: The spec.paramKind field is not allowed. Policies cannot
reference ConfigMaps or other cluster objects for parameters.
Bindings: The spec.paramRef field is not allowed. The spec.policyName
must reference a policy defined in the same manifest file set and must end
with .static.k8s.io.
Manifest files are decoded using the strict decoder, which rejects files
containing duplicate fields or unknown fields. Each object undergoes the same
defaulting and validation that the REST API applies.
Examples
Protecting API-based admission resources
A key capability of manifest-based admission control is the ability to intercept
operations on admission configuration resources themselves
(ValidatingAdmissionPolicy, MutatingAdmissionPolicy,
ValidatingWebhookConfiguration, MutatingWebhookConfiguration, and their
bindings). REST-based admission webhooks and policies are not invoked on these
resource types to prevent circular dependencies, but manifest-based policies
can enforce rules on them because they do not have that circular dependency.
The following example prevents deletion or modification of admission resources
that carry the platform.example.com/protected: "true" label:
# This is an example ValidatingAdmissionPolicy that prevents deletion or# modification of API-based admission resources with the# "platform.example.com/protected: true" label.apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"example-protect-admission-resources.static.k8s.io"annotations:kubernetes.io/description:"Prevent modification or deletion of protected admission resources"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:["admissionregistration.k8s.io"]apiVersions:["*"]operations:["DELETE","UPDATE"]resources:- "validatingadmissionpolicies"- "validatingadmissionpolicybindings"- "mutatingadmissionpolicies"- "mutatingadmissionpolicybindings"- "validatingwebhookconfigurations"- "mutatingwebhookconfigurations"validations:- expression:>- !has(oldObject.metadata.labels) ||

Enforcing a ValidatingAdmissionPolicy from disk
The following example defines a policy that denies privileged containers in all
namespaces except kube-system:
# This is an example ValidatingAdmissionPolicy that denies privileged containers# in all namespaces except kube-system.apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"example-deny-privileged.static.k8s.io"annotations:kubernetes.io/description:"Deny privileged containers outside kube-system"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:[""]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["pods"]variables:- name:allContainersexpression:>- object.spec.containers +

Place this file in the directory configured as staticManifestsDir for the
ValidatingAdmissionPolicy plugin. The policy and its binding are loaded
together atomically.
Configuring a ValidatingWebhookConfiguration from disk
The following example configures a validating webhook that calls an external URL:
# This is an example ValidatingWebhookConfiguration that calls an external# URL-based webhook endpoint to validate pod creation and updates.apiVersion:admissionregistration.k8s.io/v1kind:ValidatingWebhookConfigurationmetadata:name:"example-security-webhook.static.k8s.io"annotations:kubernetes.io/description:"Validate pod creation and updates via external webhook"webhooks:- name:"security.platform.example.com"clientConfig:url:"https://security-webhook.platform.example.com:443/validate"caBundle:"<base64-encoded-CA-bundle>"rules:- apiGroups:[""]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["pods"]admissionReviewVersions:["v1"]sideEffects:NonefailurePolicy:Fail
Note:
Webhook URLs must be reachable from the kube-apiserver at startup. Only
URL-based endpoints are supported; service references are not allowed in
manifest-based webhook configurations.
Using the List format
You can use v1.List to group related resources together in a single document:
# This is an example of using the v1.List format to group a# ValidatingAdmissionPolicy and its binding in a single document.apiVersion:v1kind:Listitems:- apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"example-require-labels.static.k8s.io"annotations:kubernetes.io/description:"Require app.kubernetes.io/name label on all pods"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:[""]apiVersions:["v1"]operations:["CREATE"]resources:["pods"]validations:- expression:>- has(object.metadata.labels) &&

Evaluation order
Manifest-based configurations are evaluated before API-based configurations.
This ensures that platform-level policies enforced via static configuration take
precedence over API-based policies.
For admission configuration resources themselves (ValidatingAdmissionPolicy,
MutatingAdmissionPolicy, ValidatingAdmissionPolicyBinding,
MutatingAdmissionPolicyBinding, ValidatingWebhookConfiguration,
MutatingWebhookConfiguration), only manifest-based admission hooks are
evaluated. API-based hooks are skipped for these resource types to prevent
circular dependencies.
File watching and dynamic reloading
The kube-apiserver watches the configured directories for changes:
Initial load: At startup, all configured paths are read and validated.
The API server does not become ready until all manifests are loaded
successfully. Invalid manifests cause startup failure.
Runtime reloading: Changes to manifest files trigger a reload cycle:
File modifications are detected using
fsnotify with a polling fallback
(default 1 minute interval), similar to other config file reloading in
kube-apiserver.
A content hash of all manifest files is computed on each check. If the hash
is unchanged, no reload occurs.
New configurations are validated before being applied.
If validation fails, the error is logged, metrics are updated, and the
previous valid configuration is retained.
Successful reloads atomically replace the previous configuration.
Atomic file updates: To avoid partial reads during file writes, make
changes atomically (for example, write to a temporary file and rename it).
This is especially important when updating mounted ConfigMaps or Secrets in
containerized environments.
Caution:
If an invalid manifest file is present at startup, the API server does not
start. At runtime, if a reload fails due to validation errors, the previous
valid configuration is retained and the error is logged.
Observability
Metrics
Manifest-based admission control provides the following metrics for monitoring
reload health:
Metrics for manifest-based admission control
Type
Description
Metric
Counter
Total number of reload attempts, with status (success or failure), plugin, and apiserver_id_hash labels.
Current configuration information (value is always 1), with plugin, apiserver_id_hash, and hash labels. Use the hash label to detect configuration drift across API servers.
The plugin label identifies which admission plugin the metric applies to:
ValidatingAdmissionWebhook, MutatingAdmissionWebhook,
ValidatingAdmissionPolicy, or MutatingAdmissionPolicy.
Since manifest-based objects have names ending in .static.k8s.io, existing
admission metrics (such as apiserver_admission_webhook_rejection_count) can
identify manifest-based decisions by filtering on the name label.
Audit annotations
Existing audit annotations (such as
validation.policy.admission.k8s.io/validation_failure and
mutation.webhook.admission.k8s.io/round_0_index_0) include the object name.
You can identify manifest-based admission decisions by filtering for names
ending in .static.k8s.io.
High availability considerations
Each kube-apiserver instance loads its own manifest files independently. In
high availability setups with multiple API server instances:
Each API server must be configured individually. There is no cross-apiserver
synchronization of manifest-based configurations.
Use external configuration management tools (such as Ansible, Puppet, or
shared storage mounts) to keep manifest files consistent across instances.
The apiserver_manifest_admission_config_controller_last_config_info metric
exposes a hash label that you can use to detect configuration drift across
API server instances.
Upgrade: Enabling the feature and providing manifest configuration is
opt-in. Existing clusters without manifest configuration see no behavioral
change.
Downgrade: Before downgrading to a version without this feature:
Remove staticManifestsDir entries from the AdmissionConfiguration file.
If relying on manifest-based policies, recreate them as API objects where
possible.
Restart the kube-apiserver.
Warning:
Downgrading without removing the staticManifestsDir configuration causes the
API server to fail to start due to unknown configuration fields.
Troubleshooting
Common issues and their resolution
Symptom
Possible cause
Resolution
API server fails to start
Invalid manifest file at startup
Check API server logs for validation errors. Fix the manifest file and restart.
API server fails to start
Duplicate object names across manifest files
Ensure all object names within a plugin's staticManifestsDir are unique.
Policies not enforced after file update
Reload validation failure
Check automatic_reloads_total{status="failure"} metric and API server logs. Fix the manifest and wait for the next reload cycle.
Webhook requests failing
Webhook URL not reachable
Verify that the URL specified in clientConfig.url is accessible from the kube-apiserver.
Cannot create API objects with .static.k8s.io suffix
Name suffix reserved by feature gate
The .static.k8s.io suffix is reserved for manifest-based configurations when the feature gate is enabled. Use a different name for API-based objects.
FEATURE STATE:Kubernetes v1.36 [stable](enabled by default)
This page provides an overview of MutatingAdmissionPolicies.
MutatingAdmissionPolicies allow you to change what happens when someone writes a change to the Kubernetes API.
If you want to use declarative policies just to prevent a particular kind of change to resources (for example: protecting platform namespaces from deletion),
ValidatingAdmissionPolicy
is
a simpler and more effective alternative.
What are MutatingAdmissionPolicies?
Mutating admission policies offer a declarative, in-process alternative to mutating admission webhooks.
Mutating admission policies use the Common Expression Language (CEL) to declare mutations to resources.
Mutations can be defined either with an apply configuration that is merged using the
server side apply merge strategy,
or a JSON patch.
Mutating admission policies are highly configurable, enabling policy authors to define policies
that can be parameterized and scoped to resources as needed by cluster administrators.
What resources make a policy
A policy is generally made up of three resources:
The MutatingAdmissionPolicy describes the abstract logic of a policy
(think: "this policy sets a particular label to a particular value").
A parameter resource provides information to a MutatingAdmissionPolicy to make it a concrete
statement (think "set the owner label to something like company.example.com").
Parameter resources refer to Kubernetes resources, available in the Kubernetes API. They can be built-in types or extensions,
such as a CustomResourceDefinition (CRD). For example, you can use a ConfigMap as a parameter.
A MutatingAdmissionPolicyBinding links the above (MutatingAdmissionPolicy and parameter) resources together and provides scoping.
If you only want to set an owner label for Pods, and not other API kinds, the binding is where you
specify this mutation.
At least a MutatingAdmissionPolicy and a corresponding MutatingAdmissionPolicyBinding
must be defined for a policy to have an effect.
Note:
Names ending in .static.k8s.io are reserved for
manifest-based admission control
and cannot be used for API-based policies or bindings. This reservation is
enforced when the ManifestBasedAdmissionControlConfigfeature gate is enabled.
If a MutatingAdmissionPolicy does not need to be configured via parameters, simply leave
spec.paramKind in MutatingAdmissionPolicy not specified.
Getting Started with MutatingAdmissionPolicies
Mutating admission policy is part of the cluster control-plane. You should write
and deploy them with great caution. The following describes how to quickly
experiment with Mutating admission policy.
Create a MutatingAdmissionPolicy
The following is an example of a MutatingAdmissionPolicy. This policy mutates newly created Pods to have a sidecar container if it does not exist.
The .spec.mutations field consists of a list of expressions that evaluate to resource patches.
The emitted patches may be either apply configurations or JSON Patch
patches. You cannot specify an empty list of mutations. After evaluating all the
expressions, the API server applies those changes to the resource that is
passing through admission.
To configure a mutating admission policy for use in a cluster, a binding is
required. The MutatingAdmissionPolicy will only be active if a corresponding
binding exists with the referenced spec.policyName matching the spec.name of
a policy.
Once the binding and policy are created, any resource request that matches the
spec.matchConditions of a policy will trigger the set of mutations defined.
In the example above, creating a Pod will add the mesh-proxy initContainer mutation:
Parameter resources allow a policy configuration to be separate from its
definition. A policy can define paramKind, which outlines GVK of the parameter
resource, and then a policy binding ties a policy by name (via policyName) to a
particular parameter resource via paramRef.
MutatingAdmissionPolicy expressions are always CEL. Each apply configuration
expression must evaluate to a CEL object (declared using Object()
initialization).
Apply configurations may not modify atomic structs, maps or arrays due to the risk of accidental deletion of
values not included in the apply configuration.
CEL expressions have access to the object types needed to create apply configurations:
Object - CEL type of the resource object.
Object.<fieldName> - CEL type of object field (such as Object.spec)
Object.<fieldName1>.<fieldName2>...<fieldNameN> - CEL type of nested field (such as Object.spec.containers)
CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables:
object - The object from the incoming request. The value is null for DELETE requests.
oldObject - The existing object. The value is null for CREATE requests.
request - Attributes of the API request.
params - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind.
namespaceObject - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources.
variables - Map of composited variables, from its name to its lazily evaluated value.
For example, a variable named foo can be accessed as variables.foo.
authorizer.requestResource - A CEL ResourceCheck constructed from the authorizer and configured with the
request resource.
The apiVersion, kind, metadata.name, metadata.generateName and metadata.labels are always accessible from the root of the object. No other metadata properties are accessible.
JSONPatch
The same mutation can be written as a JSON Patch as follows:
CEL expressions have access to the types needed to create JSON patches and objects:
JSONPatch - CEL type of JSON Patch operations. JSONPatch has the fields op, from, path and value.
See JSON patch for more details. The value field may be set to any of: string,
integer, array, map or object. If set, the path and from fields must be set to a
JSON pointer string, where the jsonpatch.escapeKey() CEL
function may be used to escape path keys containing / and ~.
Object - CEL type of the resource object.
Object.<fieldName> - CEL type of object field (such as Object.spec)
Object.<fieldName1>.<fieldName2>...<fieldNameN> - CEL type of nested field (such as Object.spec.containers)
CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables:
object - The object from the incoming request. The value is null for DELETE requests.
oldObject - The existing object. The value is null for CREATE requests.
request - Attributes of the API request.
params - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind.
namespaceObject - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources.
variables - Map of composited variables, from its name to its lazily evaluated value.
For example, a variable named foo can be accessed as variables.foo.
jsonpatch.escapeKey - Performs JSONPatch key escaping. ~ and / are escaped as ~0 and ~1 respectively.
Only property names of the form [a-zA-Z_.-/][a-zA-Z0-9_.-/]* are accessible.
API kinds exempt from mutating admission
There are certain API kinds that are exempt from admission-time mutation. For example, you can't create a MutatingAdmissionPolicy that changes a MutatingAdmissionPolicy.
Note:
When configured via
manifest-based admission control,
a MutatingAdmissionPolicy can intercept all resource types listed below.
This bypasses the restrictions usually applied to policies created via the REST
API, allowing you to mutate even admission configuration and security-sensitive
resources. Unlike the REST API, a bad manifest-based admission policy
intercepting these resources would not be unrecoverable since it is defined on
disk rather than through the API.
This page provides an overview of Validating Admission Policy.
What is Validating Admission Policy?
Validating admission policies offer a declarative, in-process alternative to validating admission webhooks.
Validating admission policies use the Common Expression Language (CEL) to declare the validation
rules of a policy.
Validation admission policies are highly configurable, enabling policy authors to define policies
that can be parameterized and scoped to resources as needed by cluster administrators.
What Resources Make a Policy
A policy is generally made up of three resources:
The ValidatingAdmissionPolicy describes the abstract logic of a policy
(think: "this policy makes sure a particular label is set to a particular value").
A parameter resource provides information to a ValidatingAdmissionPolicy to make it a concrete
statement (think "the owner label must be set to something that ends in .company.com").
A native type such as ConfigMap or a CRD defines the schema of a parameter resource.
ValidatingAdmissionPolicy objects specify what Kind they are expecting for their parameter resource.
A ValidatingAdmissionPolicyBinding links the above resources together and provides scoping.
If you only want to require an owner label to be set for Pods, the binding is where you would
specify this restriction.
At least a ValidatingAdmissionPolicy and a corresponding ValidatingAdmissionPolicyBinding
must be defined for a policy to have an effect.
Note:
Names ending in .static.k8s.io are reserved for
manifest-based admission control
and cannot be used for API-based policies or bindings. This reservation is
enforced when the ManifestBasedAdmissionControlConfigfeature gate is enabled.
If a ValidatingAdmissionPolicy does not need to be configured via parameters, simply leave
spec.paramKind in ValidatingAdmissionPolicy not specified.
Getting Started with Validating Admission Policy
Validating Admission Policy is part of the cluster control-plane. You should write and deploy them
with great caution. The following describes how to quickly experiment with Validating Admission Policy.
Creating a ValidatingAdmissionPolicy
The following is an example of a ValidatingAdmissionPolicy.
spec.validations contains CEL expressions which use the Common Expression Language (CEL)
to validate the request. If an expression evaluates to false, the validation check is enforced
according to the spec.failurePolicy field.
To configure a validating admission policy for use in a cluster, a binding is required.
The following is an example of a ValidatingAdmissionPolicyBinding.:
The above provides a simple example of using ValidatingAdmissionPolicy without a parameter configured.
Validation actions
Each ValidatingAdmissionPolicyBinding must specify one or more
validationActions to declare how validations of a policy are enforced.
The supported validationActions are:
Deny: Validation failure results in a denied request.
Warn: Validation failure is reported to the request client
as a warning.
Audit: Validation failure is included in the audit event for the API request.
For example, to both warn clients about a validation failure and to audit the
validation failures, use:
validationActions:[Warn, Audit]
Deny and Warn may not be used together since this combination
needlessly duplicates the validation failure both in the
API response body and the HTTP warning headers.
A validation that evaluates to false is always enforced according to these
actions. Failures defined by the failurePolicy are enforced
according to these actions only if the failurePolicy is set to Fail (or not specified),
otherwise the failures are ignored.
Parameter resources allow a policy configuration to be separate from its definition.
A policy can define paramKind, which outlines GVK of the parameter resource,
and then a policy binding ties a policy by name (via policyName) to a particular parameter resource via paramRef.
If parameter configuration is needed, the following is an example of a ValidatingAdmissionPolicy
with parameter configuration.
The spec.paramKind field of the ValidatingAdmissionPolicy specifies the kind of resources used
to parameterize this policy. For this example, it is configured by ReplicaLimit custom resources.
Note in this example how the CEL expression references the parameters via the CEL params variable,
e.g. params.maxReplicas. spec.matchConstraints specifies what resources this policy is
designed to validate. Note that the native types such like ConfigMap could also be used as
parameter reference.
The spec.validations fields contain CEL expressions. If an expression evaluates to false, the
validation check is enforced according to the spec.failurePolicy field.
The validating admission policy author is responsible for providing the ReplicaLimit parameter CRD.
To configure an validating admission policy for use in a cluster, a binding and parameter resource
are created. The following is an example of a ValidatingAdmissionPolicyBinding
that uses a cluster-wide param - the same param will be used to validate
every resource request that matches the binding:
This policy parameter resource limits deployments to a max of 3 replicas.
An admission policy may have multiple bindings. To bind all other environments
to have a maxReplicas limit of 100, create another ValidatingAdmissionPolicyBinding:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicyBindingmetadata:name:"replicalimit-binding-nontest"spec:policyName:"replicalimit-policy.example.com"validationActions:[Deny]paramRef:name:"replica-limit-prod.example.com"namespace:"default"parameterNotFoundAction:DenymatchResources:namespaceSelector:matchExpressions:- key:environmentoperator:NotInvalues:- test
Notice this binding applies a different parameter to resources which
are not in the test environment.
For each admission request, the API server evaluates CEL expressions of each
(policy, binding, param) combination that match the request. For a request
to be admitted it must pass all evaluations.
If multiple bindings match the request, the policy will be evaluated for each,
and they must all pass evaluation for the policy to be considered passed.
If multiple parameters match a single binding, the policy rules will be evaluated
for each param, and they too must all pass for the binding to be considered passed.
Bindings can have overlapping match criteria. The policy is evaluated for each
matching binding-parameter combination. A policy may even be evaluated multiple
times if multiple bindings match it, or a single binding that matches multiple
parameters.
The params object representing a parameter resource will not be set if a parameter resource has
not been bound, so for policies requiring a parameter resource, it can be useful to add a check to
ensure one has been bound. A parameter resource will not be bound and params will be null
if paramKind of the policy, or paramRef of the binding are not specified.
For the use cases requiring parameter configuration, we recommend to add a param check in
spec.validations[0].expression:
- expression: "params != null"
message: "params missing but required to bind to this policy"
Optional parameters
It can be convenient to be able to have optional parameters as part of a parameter resource, and
only validate them if present. CEL provides the has() macro, which checks whether a field
is present before a CEL expression accesses the field's value.
CEL also implements Boolean short-circuiting. If the first half of a logical OR evaluates to true,
it won’t evaluate the other half (since the result of the entire OR will be true regardless).
Combining the two, we can provide a way to validate optional parameters:
Here, we first check whether the optional parameter is absent with !has(params.optionalNumber).
If optionalNumber hasn’t been defined, then the expression short-circuits since
!has(params.optionalNumber) will evaluate to true.
If optionalNumber has been defined, then the latter half of the CEL expression will be
evaluated, and optionalNumber will be checked to ensure that it contains a value between 5 and
10 inclusive.
Use has() to check field presence. To check whether a map contains a key, use the in
operator instead. For example,
has(object.metadata.labels) && 'example.com/environment' in object.metadata.labels checks that
the metadata.labels field is present and that the map contains the example.com/environment key.
Per-namespace Parameters
As the author of a ValidatingAdmissionPolicy and its ValidatingAdmissionPolicyBinding,
you can choose to specify cluster-wide, or per-namespace parameters.
If you specify a namespace for the binding's paramRef, the control plane only
searches for parameters in that namespace.
However, if namespace is not specified in the ValidatingAdmissionPolicyBinding, the
API server can search for relevant parameters in the namespace that a request is against.
For example, if you make a request to modify a ConfigMap in the default namespace and
there is a relevant ValidatingAdmissionPolicyBinding with no namespace set, then the
API server looks for a parameter object in default.
This design enables policy configuration that depends on the namespace
of the resource being manipulated, for more fine-tuned control.
Parameter selector
In addition to specify a parameter in a binding by name, you may
choose instead to specify label selector, such that all resources of the
policy's paramKind, and the param's namespace (if applicable) that match the
label selector are selected for evaluation. See selector for more information on how label selectors match resources.
If multiple parameters are found to meet the condition, the policy's rules are
evaluated for each parameter found and the results will be ANDed together.
If namespace is provided, only objects of the paramKind in the provided
namespace are eligible for selection. Otherwise, when namespace is empty and
paramKind is namespace-scoped, the namespace used in the request being
admitted will be used.
Authorization checks
We introduced the authorization check for parameter resources.
User is expected to have read access to the resources referenced by paramKind in
ValidatingAdmissionPolicy and paramRef in ValidatingAdmissionPolicyBinding.
Note that if a resource in paramKind fails resolving via the restmapper, read access to all
resources of groups is required.
paramRef
The paramRef field specifies the parameter resource used by the policy. It has the following fields:
name: The name of the parameter resource.
namespace: The namespace of the parameter resource.
selector: A label selector to match multiple parameter resources.
parameterNotFoundAction: (Required) Controls the behavior when the specified parameters are not found.
Allowed Values:
Allow: The absence of matched parameters is treated as a successful validation by the binding.
Deny: The absence of matched parameters is subject to the failurePolicy of the policy.
One of name or selector must be set, but not both.
Note:
The parameterNotFoundAction field in paramRef is required. It specifies the action to take when no parameters are found matching the paramRef. If not specified, the policy binding may be considered invalid and will be ignored or could lead to unexpected behavior.
Allow: If set to Allow, and no parameters are found, the binding treats the absence of parameters as a successful validation, and the policy is considered to have passed.
Deny: If set to Deny, and no parameters are found, the binding enforces the failurePolicy of the policy. If the failurePolicy is Fail, the request is rejected.
Make sure to set parameterNotFoundAction according to the desired behavior when parameters are missing.
Handling Missing Parameters with parameterNotFoundAction
When using paramRef with a selector, it's possible that no parameters match the selector. The parameterNotFoundAction field determines how the binding behaves in this scenario.
failurePolicy defines how mis-configurations and CEL expressions evaluating to error from the
admission policy are handled. Allowed values are Ignore or Fail.
Ignore means that an error calling the ValidatingAdmissionPolicy is ignored and the API
request is allowed to continue.
Fail means that an error calling the ValidatingAdmissionPolicy causes the admission to fail
and the API request to be rejected.
Note that the failurePolicy is defined inside ValidatingAdmissionPolicy:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicyspec:...failurePolicy:Ignore# The default is "Fail"validations:- expression:"object.spec.xyz == params.x"
Validation Expression
spec.validations[i].expression represents the expression which will be evaluated by CEL.
To learn more, see the CEL language specification
CEL expressions have access to the contents of the Admission request/response, organized into CEL
variables as well as some other useful variables:
'object' - The object from the incoming request. The value is null for DELETE requests.
'oldObject' - The existing object. The value is null for CREATE requests.
'params' - Parameter resource referred to by the policy binding being evaluated. The value is
null if ParamKind is not specified.
namespaceObject - The namespace, as a Kubernetes resource, that the incoming object belongs to.
The value is null if the incoming object is cluster-scoped.
authorizer - A CEL Authorizer. May be used to perform authorization checks for the principal
(authenticated user) of the request. See
AuthzSelectors and
Authz in the Kubernetes CEL library
documentation for more details.
authorizer.requestResource - A shortcut for an authorization check configured with the request
resource (group, resource, (subresource), namespace, name).
In CEL expressions, variables like object and oldObject are strongly-typed.
You can access any field in the object's schema, such as object.metadata.labels and fields in spec.
For any Kubernetes object, including schemaless Custom Resources, CEL guarantees access to a minimal set of properties:
apiVersion, kind, metadata.name, and metadata.generateName.
Equality on arrays with list type of 'set' or 'map' ignores element order, i.e. [1, 2] == [2, 1].
Concatenation on arrays with x-kubernetes-list-type use the semantics of the list type:
'set': X + Y performs a union where the array positions of all elements in X are preserved and
non-intersecting elements in Y are appended, retaining their partial order.
'map': X + Y performs a merge where the array positions of all keys in X are preserved but the values
are overwritten by values in Y when the key sets of X and Y intersect. Elements in Y with
non-intersecting keys are appended, retaining their partial order.
spec.validation[i].reason represents a machine-readable description of why this validation failed.
If this is the first validation in the list to fail, this reason, as well as the corresponding
HTTP response code, are used in the HTTP response to the client.
The currently supported reasons are: Unauthorized, Forbidden, Invalid, RequestEntityTooLarge.
If not set, StatusReasonInvalid is used in the response to the client.
Matching requests: matchConditions
You can define match conditions for a ValidatingAdmissionPolicy if you need fine-grained request filtering. These
conditions are useful if you find that match rules, objectSelectors and namespaceSelectors still
doesn't provide the filtering you want. Match conditions are
CEL expressions. All match conditions must evaluate to true for the
resource to be evaluated.
Here is an example illustrating a few different uses for match conditions:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"demo-policy.example.com"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:["*"]apiVersions:["*"]operations:["CREATE","UPDATE"]resources:["*"]matchConditions:- name:'exclude-leases'# Each match condition must have a unique nameexpression:'!(request.resource.group == "coordination.k8s.io" && request.resource.resource == "leases")'# Match non-lease resources.- name:'exclude-kubelet-requests'expression:'!("system:nodes" in request.userInfo.groups)'# Match requests made by non-node users.- name:'rbac'# Skip RBAC requests.expression:'request.resource.group != "rbac.authorization.k8s.io"'validations:- expression:"!object.metadata.name.contains('demo') || object.metadata.namespace == 'demo'"
Match conditions have access to the same CEL variables as validation expressions.
In the event of an error evaluating a match condition the policy is not evaluated. Whether to reject
the request is determined as follows:
If any match condition evaluated to false (regardless of other errors), the API server skips the policy.
Otherwise:
for failurePolicy: Fail, reject the request (without evaluating the policy).
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"demo-policy.example.com"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:["apps"]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["deployments"]validations:- expression:"object.spec.replicas > 50"messageExpression:"'Deployment spec.replicas set to ' + string(object.spec.replicas)"auditAnnotations:- key:"high-replica-count"valueExpression:"'Deployment spec.replicas set to ' + string(object.spec.replicas)"
When an API request is validated with this admission policy, the resulting audit event will look like:
# the audit event recorded
{
"kind": "Event",
"apiVersion": "audit.k8s.io/v1",
"annotations": {
"demo-policy.example.com/high-replica-count": "Deployment spec.replicas set to 128"
# other annotations
...
}
# other fields
...
}
In this example the annotation will only be included if the spec.replicas of the Deployment is more than
50, otherwise the CEL expression evaluates to null and the annotation will not be included.
Note that audit annotation keys are prefixed by the name of the ValidatingAdmissionPolicy and a /. If
another admission controller, such as an admission webhook, uses the exact same audit annotation key, the
value of the first admission controller to include the audit annotation will be included in the audit
event and all other values will be ignored.
Message expression
To return a more friendly message when the policy rejects a request, we can use a CEL expression
to composite a message with spec.validations[i].messageExpression. Similar to the validation expression,
a message expression has access to object, oldObject, request, params, and namespaceObject.
Unlike validations, message expression must evaluate to a string.
For example, to better inform the user of the reason of denial when the policy refers to a parameter,
we can have the following validation:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"deploy-replica-policy.example.com"spec:paramKind:apiVersion:rules.example.com/v1kind:ReplicaLimitmatchConstraints:resourceRules:- apiGroups:["apps"]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["deployments"]validations:- expression:"object.spec.replicas <= params.maxReplicas"messageExpression:"'object.spec.replicas must be no greater than ' + string(params.maxReplicas)"reason:Invalid
After creating a params object that limits the replicas to 3 and setting up the binding,
when we try to create a deployment with 5 replicas, we will receive the following message.
$ kubectl create deploy --image=nginx nginx --replicas=5
error: failed to create deployment: deployments.apps "nginx" is forbidden: ValidatingAdmissionPolicy 'deploy-replica-policy.example.com' with binding 'demo-binding-test.example.com' denied request: object.spec.replicas must be no greater than 3
This is more informative than a static message of "too many replicas".
The message expression takes precedence over the static message defined in spec.validations[i].message if both are defined.
However, if the message expression fails to evaluate, the static message will be used instead.
Additionally, if the message expression evaluates to a multi-line string,
the evaluation result will be discarded and the static message will be used if present.
Note that static message is validated against multi-line strings.
Type checking
When a policy definition is created or updated, the validation process parses the expressions it contains
and reports any syntax errors, rejecting the definition if any errors are found.
Afterward, the referred variables are checked for type errors, including missing fields and type confusion,
against the matched types of spec.matchConstraints.
The result of type checking can be retrieved from status.typeChecking.
The presence of status.typeChecking indicates the completion of type checking,
and an empty status.typeChecking means that no errors were detected.
For example, given the following policy definition:
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"deploy-replica-policy.example.com"spec:matchConstraints:resourceRules:- apiGroups:["apps"]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["deployments"]validations:- expression:"object.replicas > 1"# should be "object.spec.replicas > 1"message:"must be replicated"reason:Invalid
If multiple resources are matched in spec.matchConstraints, all of matched resources will be checked against.
For example, the following policy definition
apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"replica-policy.example.com"spec:matchConstraints:resourceRules:- apiGroups:["apps"]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["deployments","replicasets"]validations:- expression:"object.replicas > 1"# should be "object.spec.replicas > 1"message:"must be replicated"reason:Invalid
will have multiple types and type checking result of each type in the warning message.
No wildcard matching. If spec.matchConstraints.resourceRules contains "*" in any of apiGroups, apiVersions or resources,
the types that "*" matches will not be checked.
The number of matched types is limited to 10. This is to prevent a policy that manually specifying too many types.
to consume excessive computing resources. In the order of ascending group, version, and then resource, 11th combination and beyond are ignored.
Type Checking does not affect the policy behavior in any way. Even if the type checking detects errors, the policy will continue
to evaluate. If errors do occur during evaluate, the failure policy will decide its outcome.
Type Checking does not apply to CRDs, including matched CRD types and reference of paramKind. The support for CRDs will come in future release.
Variable composition
If an expression grows too complicated, or part of the expression is reusable and computationally expensive to evaluate,
you can extract some part of the expressions into variables. A variable is a named expression that can be referred later
in variables in other expressions.
A variable is lazily evaluated when it is first referred. Any error that occurs during the evaluation will be
reported during the evaluation of the referring expression. Both the result and potential error are memorized and
count only once towards the runtime cost.
The order of variables are important because a variable can refer to other variables that are defined before it.
This ordering prevents circular references.
The following is a more complex example of enforcing that image repo names match the environment defined in its namespace.
# This policy enforces that all containers of a deployment has the image repo match the environment label of its namespace.# Except for "exempt" deployments, or any containers that do not belong to the "example.com" organization (e.g. common sidecars).# For example, if the namespace has a label of {"environment": "staging"}, all container images must be either staging.example.com/*# or do not contain "example.com" at all, unless the deployment has {"exempt": "true"} label.apiVersion:admissionregistration.k8s.io/v1kind:ValidatingAdmissionPolicymetadata:name:"image-matches-namespace-environment.policy.example.com"spec:failurePolicy:FailmatchConstraints:resourceRules:- apiGroups:["apps"]apiVersions:["v1"]operations:["CREATE","UPDATE"]resources:["deployments"]variables:- name:environmentexpression:"'environment' in namespaceObject.metadata.labels ? namespaceObject.metadata.labels['environment'] : 'prod'"- name:exemptexpression:"'exempt' in object.metadata.labels && object.metadata.labels['exempt'] == 'true'"- name:containersexpression:"object.spec.template.spec.containers"- name:containersToCheckexpression:"variables.containers.filter(c, c.image.contains('example.com/'))"validations:- expression:"variables.exempt || variables.containersToCheck.all(c, c.image.startsWith(variables.environment + '.'))"messageExpression:"'only ' + variables.environment + ' images are allowed in namespace ' + namespaceObject.metadata.name"
With the policy bound to the namespace default, which is labeled environment: prod,
the following attempt to create a deployment would be rejected.
error: failed to create deployment: deployments.apps "invalid" is forbidden: ValidatingAdmissionPolicy 'image-matches-namespace-environment.policy.example.com' with binding 'demo-binding-test.example.com' denied request: only prod images are allowed in namespace default
API kinds exempt from admission validation
There are certain API kinds that are exempt from admission-time validation checks. For example, you can't create a ValidatingAdmissionPolicy that prevents changes to ValidatingAdmissionPolicyBindings.
Note:
When configured via
manifest-based admission control,
a ValidatingAdmissionPolicy can intercept all resource types listed below.
This bypasses the restrictions usually applied to policies created via the REST
API, allowing you to validate even admission configuration and
security-sensitive resources. Unlike the REST API, a bad manifest-based
admission policy intercepting these resources would not be unrecoverable since
it is defined on disk rather than through the API.
If this annotation is set to true on a FlowSchema or PriorityLevelConfiguration, the spec for that object
is managed by the kube-apiserver. If the API server does not recognize an APF object, and you annotate it
for automatic update, the API server deletes the entire object. Otherwise, the API server does not manage the
object spec.
For more details, read Maintenance of the Mandatory and Suggested Configuration Objects.
Use of this annotation is Alpha.
For Kubernetes version 1.36, you can use this annotation on Secrets,
ConfigMaps, or custom resources if the
CustomResourceDefinition
defining them has the applyset.kubernetes.io/is-parent-type label.
Part of the specification used to implement
ApplySet-based pruning in kubectl.
This annotation is applied to the parent object used to track an ApplySet to extend the scope of
the ApplySet beyond the parent object's own namespace (if any).
The value is a comma-separated list of the names of namespaces other than the parent's namespace
in which objects are found.
Use of this annotation is Alpha.

This annotation is applied to the parent object used to track an ApplySet to optimize listing of
ApplySet member objects. It is optional in the ApplySet specification, as tools can perform discovery
or use a different optimization. However, as of Kubernetes version 1.36,
it is required by kubectl. When present, the value of this annotation must be a comma separated list
of the group-kinds, in the fully-qualified name format, i.e. <resource>.<group>.

the hash of the group-kind-name-namespace of the object it is on, in the form:
<base64(sha256(<name>.<namespace>.<kind>.<group>))>.
There is no relation between the value of this label and object UID.
Use of this label is Alpha.
Part of the specification used to implement
ApplySet-based pruning in kubectl.
You can set this label on a CustomResourceDefinition (CRD) to identify the custom resource type it
defines (not the CRD itself) as an allowed parent for an ApplySet.
The only permitted value for this label is "true"; if you want to mark a CRD as
not being a valid parent for ApplySets, omit this label.
Use of this label is Alpha.
Part of the specification used to implement
ApplySet-based pruning in kubectl.
This label is what makes an object a member of an ApplySet.
The value of the label must match the value of the applyset.kubernetes.io/id
label on the parent object.
Use of this annotation is Alpha.
For Kubernetes version 1.36, you can use this annotation on Secrets,
ConfigMaps, or custom resources if the CustomResourceDefinitiondefining them has the
applyset.kubernetes.io/is-parent-type label.
Part of the specification used to implement
ApplySet-based pruning in kubectl.
This annotation is applied to the parent object used to track an ApplySet to indicate which
tooling manages that ApplySet. Tooling should refuse to mutate ApplySets belonging to other tools.
The value must be in the format <toolname>/<semver>.
apps.kubernetes.io/pod-index (beta)
Type: Label
Example: apps.kubernetes.io/pod-index: "0"
Used on: Pod
When a StatefulSet controller creates a Pod for the StatefulSet, it sets this label on that Pod.
The value of the label is the ordinal index of the pod being created.
See Pod Index Label
in the StatefulSet topic for more details.
Note the PodIndexLabel
feature gate must be enabled for this label to be added to pods.
This annotation is assigned to generated ResourceClaims.
Its value corresponds to the name of the resource claim in the .spec of any Pod(s) for which the ResourceClaim was created.
Within dynamic resource allocation, the
discoverable device metadata feature uses this annotation to map a generated ResourceClaim
back to the Pod claim name (pod.spec.resourceClaims[].name) for template-based claims.
Kubernetes manages this annotation, so you should not modify it.
When this annotation is set to "true", the cluster autoscaler is allowed to evict a Pod
even if other rules would normally prevent that.
The cluster autoscaler never evicts Pods that have this annotation explicitly set to
"false"; you could set that on an important Pod that you want to keep running.
If this annotation is not set then the cluster autoscaler follows its Pod-level behavior.
This annotation is used in manifests to mark an object as local configuration that
should not be submitted to the Kubernetes API.
A value of "true" for this annotation declares that the object is only consumed by
client-side tooling and should not be submitted to the API server.
A value of "false" can be used to declare that the object should be submitted to
the API server even when it would otherwise be assumed to be local.
This annotation is part of the Kubernetes Resource Model (KRM) Functions Specification,
which is used by Kustomize and similar third-party tools.
For example, Kustomize removes objects with this annotation from its final build output.
This annotation allows you to specify the AppArmor security profile for a container within a
Kubernetes pod. As of Kubernetes v1.30, this should be set with the appArmorProfile field instead.
To learn more, see the AppArmor tutorial.
The tutorial illustrates using AppArmor to restrict a container's abilities and access.
The profile specified dictates the set of rules and restrictions that the containerized process must
adhere to. This helps enforce security policies and isolation for your containers.
This annotation is set by the Deployment controller on ReplicaSets it manages.
The value represents the desired number of replicas (.spec.replicas) from the Deployment
that owns this ReplicaSet. The Deployment controller uses this annotation to track the
desired state during rolling updates and scaling operations.
This is an internal annotation used by the Deployment controller and should not be
modified manually.
This annotation is set by the Deployment controller on ReplicaSets it manages.
The value represents the maximum number of replicas that this ReplicaSet is allowed to have
during a rolling update. This is used to implement the maxSurge parameter of the
Deployment's rolling update strategy, which controls how many extra Pods can be created
above the desired number during an update.
This is an internal annotation used by the Deployment controller and should not be
modified manually.
deployment.kubernetes.io/revision
Type: Annotation
Example: deployment.kubernetes.io/revision: "2"
Used on: ReplicaSet
This annotation is set by the Deployment controller on ReplicaSets it manages.
The value represents the revision number of the Deployment. Each time the Deployment's
Pod template (.spec.template) is changed, the revision number is incremented.
This annotation is used to track the rollout history and enables rollback to previous
revisions using kubectl rollout undo.
The revision number is also visible when running kubectl rollout history deployment/<name>.
This is an internal annotation used by the Deployment controller and should not be
modified manually.
This annotation is set by the Deployment controller on a ReplicaSet when a rollback
causes that ReplicaSet to be reused. The value is a comma-separated list of all
previous revision numbers that the ReplicaSet has served for a Deployment, maintained
as a history when the deployment.kubernetes.io/revision annotation is updated to a
new revision number.
This is an internal annotation used by the Deployment controller and should not be
modified manually.
internal.config.kubernetes.io/* (reserved prefix)
Type: Annotation
Used on: All objects
This prefix is reserved for internal use by tools that act as orchestrators in accordance
with the Kubernetes Resource Model (KRM) Functions Specification.
Annotations with this prefix are internal to the orchestration process and are not persisted to
the manifests on the filesystem. In other words, the orchestrator tool should set these
annotations when reading files from the local filesystem and remove them when writing the output
of functions back to the filesystem.
A KRM function must not modify annotations with this prefix, unless otherwise specified for a
given annotation. This enables orchestrator tools to add additional internal annotations, without
requiring changes to existing functions.
This annotation records the slash-delimited, OS-agnostic, relative path to the manifest file the
object was loaded from. The path is relative to a fixed location on the filesystem, determined by
the orchestrator tool.
This annotation is part of the Kubernetes Resource Model (KRM) Functions Specification, which is
used by Kustomize and similar third-party tools.
A KRM Function should not modify this annotation on input objects unless it is modifying the
referenced files. A KRM Function may include this annotation on objects it generates.
internal.config.kubernetes.io/index
Type: Annotation
Example: internal.config.kubernetes.io/index: "2"
Used on: All objects
This annotation records the zero-indexed position of the YAML document that contains the object
within the manifest file the object was loaded from. Note that YAML documents are separated by
three dashes (---) and can each contain one object. When this annotation is not specified, a
value of 0 is implied.
This annotation is part of the Kubernetes Resource Model (KRM) Functions Specification,
which is used by Kustomize and similar third-party tools.
A KRM Function should not modify this annotation on input objects unless it is modifying the
referenced files. A KRM Function may include this annotation on objects it generates.
The Kubelet populates this with runtime.GOARCH as defined by Go.
This can be handy if you are mixing ARM and x86 nodes.
kubernetes.io/os
Type: Label
Example: kubernetes.io/os: "linux"
Used on: Node, Pod
For nodes, the kubelet populates this with runtime.GOOS as defined by Go. This can be handy if you are
mixing operating systems in your cluster (for example: mixing Linux and Windows nodes).
You can also set this label on a Pod. Kubernetes allows you to set any value for this label;
if you use this label, you should nevertheless set it to the Go runtime.GOOS string for the operating
system that this Pod actually works with.
When the kubernetes.io/os label value for a Pod does not match the label value on a Node,
the kubelet on the node will not admit the Pod. However, this is not taken into account by
the kube-scheduler. Alternatively, the kubelet refuses to run a Pod where you have specified a Pod OS, if
this isn't the same as the operating system for the node where that kubelet is running. Just
look for Pods OS for more details.
The Kubernetes API server (part of the control plane)
sets this label on all namespaces. The label value is set
to the name of the namespace. You can't change this label's value.
This is useful if you want to target a specific namespace with a label
selector.
kubernetes.io/limit-ranger
Type: Annotation
Example: kubernetes.io/limit-ranger: "LimitRanger plugin set: cpu, memory request for container nginx; cpu, memory limit for container nginx"
Used on: Pod
Kubernetes by default doesn't provide any resource limit, that means unless you explicitly define
limits, your container can consume unlimited CPU and memory.
You can define a default request or default limit for pods. You do this by creating a LimitRange
in the relevant namespace. Pods deployed after you define a LimitRange will have these limits
applied to them.
The annotation kubernetes.io/limit-ranger records that resource defaults were specified for the Pod,
and they were applied successfully.
For more details, read about LimitRanges.
When the kubelet creates a static Pod based on a given manifest, it attaches this annotation
to the static Pod. The value of the annotation is the UID of the Pod.
Note that the kubelet also sets the .spec.nodeName to the current node name as if the Pod
was scheduled to the node.
For a static Pod created by the kubelet on a node, a mirror Pod
is created on the API server. The kubelet adds an annotation to indicate that this Pod is
actually a mirror Pod. The annotation value is copied from the kubernetes.io/config.hash
annotation, which is the UID of the Pod.
When updating a Pod with this annotation set, the annotation cannot be changed or removed.
If a Pod doesn't have this annotation, it cannot be added during a Pod update.
kubernetes.io/config.source
Type: Annotation
Example: kubernetes.io/config.source: "file"
Used on: Pod
This annotation is added by the kubelet to indicate where the Pod comes from.
For static Pods, the annotation value could be one of file or http depending
on where the Pod manifest is located. For a Pod created on the API server and then
scheduled to the current node, the annotation value is api.
To specify how an add-on should be managed, you can use the addonmanager.kubernetes.io/mode label.
This label can have one of three values: Reconcile, EnsureExists, or Ignore.
Reconcile: Addon resources will be periodically reconciled with the expected state.
If there are any differences, the add-on manager will recreate, reconfigure or delete
the resources as needed. This is the default mode if no label is specified.
EnsureExists: Addon resources will be checked for existence only but will not be modified
after creation. The add-on manager will create or re-create the resources when there is
no instance of the resource with that name.
Ignore: Addon resources will be ignored. This mode is useful for add-ons that are not
compatible with the add-on manager or that are managed by another controller.
The kube-apiserver sets this label on any APIService object that the API server
has created automatically. The label marks how the control plane should manage that
APIService. You should not add, modify, or remove this label by yourself.
Note:
Automanaged APIService objects are deleted by kube-apiserver when it has no built-in
or custom resource API corresponding to the API group/version of the APIService.
There are two possible values:
onstart: The APIService should be reconciled when an API server starts up, but not otherwise.
true: The API server should reconcile this APIService continuously.
This annotation was formerly used to indicate that the Endpoints controller
should create Endpoints for unready Pods. Since Kubernetes 1.11, the preferred
API for this feature has been the .publishNotReadyAddresses field on the
Service. This annotation has no effect in
Kubernetes 1.36.
This annotation was used to configure the scaling behavior for a HorizontalPodAutoscaler (HPA) in earlier Kubernetes versions.
It allowed you to specify how the HPA should scale pods up or down, including setting stabilization windows and scaling policies.
Setting this annotation has no effect in any supported release of Kubernetes.
The Kubelet populates this label with the hostname of the node. Note that the hostname
can be changed from the "actual" hostname by passing the --hostname-override flag to
the kubelet.
This label is also used as part of the topology hierarchy.
See topology.kubernetes.io/zone for more information.
kubernetes.io/enforce-mountable-secrets is deprecated since Kubernetes v1.32. Use separate namespaces to isolate access to mounted secrets.
The value for this annotation must be true to take effect.
When you set this annotation to "true", Kubernetes enforces the following rules for
Pods running as this ServiceAccount:
Secrets mounted as volumes must be listed in the ServiceAccount's secrets field.
Secrets referenced in envFrom for containers (including sidecar containers and init containers)
must also be listed in the ServiceAccount's secrets field.
If any container in a Pod references a Secret not listed in the ServiceAccount's secrets field
(and even if the reference is marked as optional), then the Pod will fail to start,
and an error indicating the non-compliant secret reference will be generated.
Secrets referenced in a Pod's imagePullSecrets must be present in the
ServiceAccount's imagePullSecrets field, the Pod will fail to start,
and an error indicating the non-compliant image pull secret reference will be generated.
When you create or update a Pod, these rules are checked. If a Pod doesn't follow them, it won't start and you'll see an error message.
If a Pod is already running and you change the kubernetes.io/enforce-mountable-secrets annotation
to true, or you edit the associated ServiceAccount to remove the reference to a Secret
that the Pod is already using, the Pod continues to run.
node.alpha.kubernetes.io/ttl (deprecated)
Type: Label
Example: node.alpha.kubernetes.io/ttl: "0"
Used on: Node
This label was used historically by some tools (such as minikube) to set a time-to-live
value for nodes. The label is deprecated and should not be used in new deployments.
Note:
This label is deprecated and has no effect in current Kubernetes versions.
It may still be set by older tools for backward compatibility.
You can add labels to particular worker nodes to exclude them from the list of backend servers used by external load balancers.
The following command can be used to exclude a worker node from the list of backend servers in a
backend set:
This annotation is used to set Pod Deletion Cost
which allows users to influence ReplicaSet downscaling order.
The annotation value parses into an int32 type.
This annotation controls whether a DaemonSet pod should be evicted by a ClusterAutoscaler.
This annotation needs to be specified on DaemonSet pods in a DaemonSet manifest.
When this annotation is set to "true", the ClusterAutoscaler is allowed to evict
a DaemonSet Pod, even if other rules would normally prevent that.
To disallow the ClusterAutoscaler from evicting DaemonSet pods,
you can set this annotation to "false" for important DaemonSet pods.
If this annotation is not set, then the ClusterAutoscaler follows its overall behavior
(i.e evict the DaemonSets based on its configuration).
Note:
This annotation only impacts DaemonSet Pods.
kubernetes.io/ingress-bandwidth
Type: Annotation
Example: kubernetes.io/ingress-bandwidth: 10M
Used on: Pod
You can apply quality-of-service traffic shaping to a pod and effectively limit its available
bandwidth. Ingress traffic to a Pod is handled by shaping queued packets to effectively
handle data. To limit the bandwidth on a Pod, write an object definition JSON file and specify
the data traffic speed using kubernetes.io/ingress-bandwidth annotation. The unit used for
specifying ingress rate is bits per second, as a
Quantity.
For example, 10M means 10 megabits per second.
Note:
Ingress traffic shaping annotation is an experimental feature.
If you want to enable traffic shaping support, you must add the bandwidth plugin to your CNI
configuration file (default /etc/cni/net.d) and ensure that the binary is included in your CNI
bin dir (default /opt/cni/bin).
kubernetes.io/egress-bandwidth
Type: Annotation
Example: kubernetes.io/egress-bandwidth: 10M
Used on: Pod
Egress traffic from a Pod is handled by policing, which simply drops packets in excess of the
configured rate. The limits you place on a Pod do not affect the bandwidth of other Pods.
To limit the bandwidth on a Pod, write an object definition JSON file and specify the data traffic
speed using kubernetes.io/egress-bandwidth annotation. The unit used for specifying egress rate
is bits per second, as a Quantity.
For example, 10M means 10 megabits per second.
Note:
Egress traffic shaping annotation is an experimental feature.
If you want to enable traffic shaping support, you must add the bandwidth plugin to your CNI
configuration file (default /etc/cni/net.d) and ensure that the binary is included in your CNI
bin dir (default /opt/cni/bin).
The Kubelet populates this with the instance type as defined by the cloud provider.
This will be set only if you are using a cloud provider. This setting is handy
if you want to target certain workloads to certain instance types, but typically you want
to rely on the Kubernetes scheduler to perform resource-based scheduling.
You should aim to schedule based on properties rather than on instance types
(for example: require a GPU, instead of requiring a g2.2xlarge).
When this annotation is set on a PersistentVolumeClaim (PVC), that indicates that the lifecycle
of the PVC has passed through initial binding setup. When present, that information changes
how the control plane interprets the state of PVC objects.
The value of this annotation does not matter to Kubernetes.
If this annotation is set on a PersistentVolume or PersistentVolumeClaim, it indicates that a
storage binding (PersistentVolume → PersistentVolumeClaim, or PersistentVolumeClaim → PersistentVolume)
was installed by the controller.
If the annotation isn't set, and there is a storage binding in place, the absence of that
annotation means that the binding was done manually.
The value of this annotation does not matter.
This annotation is added to a PersistentVolume(PV) that has been dynamically provisioned by Kubernetes.
Its value is the name of volume plugin that created the volume. It serves both users (to show where a PV
comes from) and Kubernetes (to recognize dynamically provisioned PVs in its decisions).
It is added to a PersistentVolume(PV) and PersistentVolumeClaim(PVC) that is supposed to be
dynamically provisioned/deleted by its corresponding CSI driver through the CSIMigration feature gate.
When this annotation is set, the Kubernetes components will "stand-down" and the
external-provisioner will act on the objects.
When a StatefulSet controller creates a Pod for the StatefulSet, the control plane
sets this label on that Pod. The value of the label is the name of the Pod being created.
See Pod Name Label
in the StatefulSet topic for more details.
On Node: The kubelet or the external cloud-controller-manager populates this
with the information from the cloud provider. This will be set only if you are using
a cloud provider. However, you can consider setting this on nodes if it makes sense
in your topology.
On PersistentVolume: topology-aware volume provisioners will automatically set
node affinity constraints on a PersistentVolume.
A zone represents a logical failure domain. It is common for Kubernetes clusters to
span multiple zones for increased availability. While the exact definition of a zone
is left to infrastructure implementations, common properties of a zone include
very low network latency within a zone, no-cost network traffic within a zone, and
failure independence from other zones.
For example, nodes within a zone might share a network switch, but nodes in different
zones should not.
A region represents a larger domain, made up of one or more zones.
It is uncommon for Kubernetes clusters to span multiple regions,
While the exact definition of a zone or region is left to infrastructure implementations,
common properties of a region include higher network latency between them than within them,
non-zero cost for network traffic between them, and failure independence from other zones or regions.
For example, nodes within a region might share power infrastructure (e.g. a UPS or generator),
but nodes in different regions typically would not.
Kubernetes makes a few assumptions about the structure of zones and regions:
regions and zones are hierarchical: zones are strict subsets of regions and
no zone can be in 2 regions
zone names are unique across regions; for example region "africa-east-1" might be comprised
of zones "africa-east-1a" and "africa-east-1b"
It should be safe to assume that topology labels do not change.
Even though labels are strictly mutable, consumers of them can assume that a given node
is not going to be moved between zones without being destroyed and recreated.
Kubernetes can use this information in various ways.
For example, the scheduler automatically tries to spread the Pods in a ReplicaSet across nodes
in a single-zone cluster (to reduce the impact of node failures, see
kubernetes.io/hostname).
With multiple-zone clusters, this spreading behavior also applies to zones (to reduce the impact of zone failures).
This is achieved via SelectorSpreadPriority.
SelectorSpreadPriority is a best effort placement. If the zones in your cluster are
heterogeneous (for example: different numbers of nodes, different types of nodes, or different pod
resource requirements), this placement might prevent equal spreading of your Pods across zones.
If desired, you can use homogeneous zones (same number and types of nodes) to reduce the probability
of unequal spreading.
The scheduler (through the VolumeZonePredicate predicate) also will ensure that Pods,
that claim a given volume, are only placed into the same zone as that volume.
Volumes cannot be attached across zones.
If PersistentVolumeLabel does not support automatic labeling of your PersistentVolumes,
you should consider adding the labels manually (or adding support for PersistentVolumeLabel).
With PersistentVolumeLabel, the scheduler prevents Pods from mounting volumes in a different zone.
If your infrastructure doesn't have this constraint, you don't need to add the zone labels to the volumes at all.
This annotation can be used for PersistentVolume(PV) or PersistentVolumeClaim(PVC)
to specify the name of StorageClass.
When both the storageClassName attribute and the volume.beta.kubernetes.io/storage-class
annotation are specified, the annotation volume.beta.kubernetes.io/storage-class
takes precedence over the storageClassName attribute.
This annotation has been deprecated. Instead, set the
storageClassName field
for the PersistentVolumeClaim or PersistentVolume.
Example : volume.beta.kubernetes.io/mount-options: "ro,soft"
Used on: PersistentVolume
A Kubernetes administrator can specify additional
mount options
for when a PersistentVolume is mounted on a node.
volume.kubernetes.io/storage-provisioner
Type: Annotation
Used on: PersistentVolumeClaim
This annotation is added to a PVC that is supposed to be dynamically provisioned.
Its value is the name of a volume plugin that is supposed to provision a volume
for this PVC.
volume.kubernetes.io/selected-node
Type: Annotation
Used on: PersistentVolumeClaim
This annotation is added to a PVC that is triggered by a scheduler to be
dynamically provisioned. Its value is the name of the selected node.
If a node has the annotation volumes.kubernetes.io/controller-managed-attach-detach,
its storage attach and detach operations are being managed by the volume attach/detachcontroller.
This annotation is automatically added for the CSINode object that maps to a node that
installs CSIDriver. This annotation shows the in-tree plugin name of the migrated plugin. Its
value depends on your cluster's in-tree cloud provider storage type.
For example, if the in-tree cloud provider storage type is CSIMigrationvSphere, the CSINodes instance for the node should be updated with:
storage.alpha.kubernetes.io/migrated-plugins: "kubernetes.io/vsphere-volume"
service.kubernetes.io/headless
Type: Label
Example: service.kubernetes.io/headless: ""
Used on: EndpointSlice, Endpoints
The control plane adds
this label to EndpointSlice and
Endpoints objects when the owning Service is
headless (as a hint to the service proxy that it can ignore these endpoints). To
learn more, read Headless
Services.
Example: service.kubernetes.io/topology-mode: Auto
Used on: Service
This annotation provides a way to define how Services handle network topology;
for example, you can configure a Service so that Kubernetes prefers keeping traffic between
a client and server within a single topology zone.
In some cases this can help reduce costs or improve network performance.
This label records the name of the
Service that the EndpointSlice is backing. All EndpointSlices should have this label set to
the name of their associated Service.
This annotation records the unique ID of the
ServiceAccount that the token (stored in the Secret of type kubernetes.io/service-account-token)
represents.
The control plane only adds this label to Secrets that have the type
kubernetes.io/service-account-token.
The value of this label records the date (ISO 8601 format, UTC time zone) when the control plane
last saw a request where the client authenticated using the service account token.
If a legacy token was last used before the cluster gained the feature (added in Kubernetes v1.26),
then the label isn't set.
The control plane automatically adds this label to auto-generated Secrets that
have the type kubernetes.io/service-account-token. This label marks the
Secret-based token as invalid for authentication. The value of this label
records the date (ISO 8601 format, UTC time zone) when the control plane detects
that the auto-generated Secret has not been used for a specified duration
(defaults to one year).
This label is used internally to mark Endpoints objects that were created by
Kubernetes (as opposed to Endpoints created by users or external controllers).
The label is used to indicate the controller or entity that manages the EndpointSlice. This label
aims to enable different EndpointSlice objects to be managed by different controllers or entities
within the same cluster. The value endpointslice-controller.k8s.io indicates an
EndpointSlice object that was created automatically by Kubernetes for a Service with a
selectors.
The label can be set to "true" on an Endpoints resource to indicate that the
EndpointSliceMirroring controller should not mirror this resource with EndpointSlices.
Setting a value for this label tells kube-proxy to ignore this service for proxying purposes.
This allows for use of alternative proxy implementations for this service (e.g. running
a DaemonSet that manages nftables its own way). Multiple alternative proxy implementations
could be active simultaneously using this field, e.g. by having a value unique to each
alternative proxy implementation to be responsible for their respective services.
Used on: Gateway, HTTPRoute, and other Gateway API resources
This annotation is added by tools that automatically generate
Gateway API resources.
The value identifies the tool that created the resource (for example,
ingress2gateway). The annotation is informational only and does not
affect the behavior of any Gateway API implementation.
When a IngressClass resource has this annotation set to "true", new Ingress resource
without a class specified will be assigned this default class.
kubernetes.io/ingress.class (deprecated)
Type: Annotation
Used on: Ingress
Note:
Starting in v1.18, this annotation is deprecated in favor of spec.ingressClassName.
kubernetes.io/cluster-service (deprecated)
Type: Label
Example: kubernetes.io/cluster-service: "true"
Used on: Service
This label indicates that the Service provides a service to the cluster, if the value is set to true.
When you run kubectl cluster-info, the tool queries for Services with this label set to true.
However, setting this label on any Service is deprecated.
When a single StorageClass resource has this annotation set to "true", new PersistentVolumeClaim
resource without a class specified will be assigned this default class.
The kubelet can set this annotation on a Node to denote its configured IPv4 and/or IPv6 address.
When kubelet is started with the --cloud-provider flag set to any value (includes both external
and legacy in-tree cloud providers), it sets this annotation on the Node to denote an IP address
set from the command line flag (--node-ip). This IP is verified with the cloud provider as valid
by the cloud-controller-manager.
This annotation is used to record the original (expected) creation timestamp for a Job,
when that Job is part of a CronJob.
The control plane sets the value to that timestamp in RFC3339 format. If the Job belongs to a CronJob
with a timezone specified, then the timestamp is in that timezone. Otherwise, the timestamp is in controller-manager's local time.
When you use kubectl create job with the --from=cronjob/<cronjob-name> flag to manually create a Job from an existing CronJob template, kubectl sets this annotation on the newly created Job.
The value of this annotation is always manual. This annotation allows you to distinguish
Jobs that were created on demand by a user from Jobs that the CronJob controller automatically creates on their scheduled time.
The value of the annotation is the container name that is default for this Pod.
For example, kubectl logs or kubectl exec without -c or --container flag
will use this default container.
The value of the annotation is the container name that is the default logging container for this
Pod. For example, kubectl logs without -c or --container flag will use this default
container.
Note:
This annotation is deprecated. You should use the
kubectl.kubernetes.io/default-container
annotation instead. Kubernetes versions 1.25 and newer ignore this annotation.
Used on: Deployment, ReplicaSet, StatefulSet, DaemonSet, Pod
This annotation contains the latest restart time of a resource (Deployment, ReplicaSet, StatefulSet or DaemonSet),
where kubectl triggered a rollout in order to force creation of new Pods.
The command kubectl rollout restart <RESOURCE> triggers a restart by patching the template
metadata of all the pods of resource with this annotation. In above example the latest restart time is shown as 21st June 2024 at 17:27:41 UTC.
You should not assume that this annotation represents the date / time of the most recent update;
a separate change could have been made since the last manually triggered rollout.
If you manually set this annotation on a Pod, nothing happens. The restarting side effect comes from
how workload management and Pod templating works.
The control plane adds this annotation to
an Endpoints object if the associated
Service has more than 1000 backing endpoints.
The annotation indicates that the Endpoints object is over capacity and the number of endpoints
has been truncated to 1000.
If the number of backend endpoints falls below 1000, the control plane removes this annotation.
Note:
The Endpoints
API is deprecated in favor of
EndpointSlice.
A Service can have multiple EndpointSlice objects. As a result, EndpointSlices do not require truncation.
This annotation set to an Endpoints object that
represents the timestamp (The timestamp is stored in RFC 3339 date-time string format. For example, '2018-10-22T19:32:52.1Z'). This is timestamp
of the last change in some Pod or Service object, that triggered the change to the Endpoints object.
The control plane previously used
an Endpoints object to
coordinate leader assignment for the Kubernetes control plane. This Endpoints
object included an annotation with the following detail:
Who is the current leader.
The time when the current leadership was acquired.
The duration of the lease (of the leadership) in seconds.
The time the current lease (the current leadership) should be renewed.
The number of leadership transitions that happened in the past.
Kubernetes now uses Leases to
manage leader assignment for the Kubernetes control plane.
batch.kubernetes.io/job-tracking (deprecated)
Type: Annotation
Example: batch.kubernetes.io/job-tracking: ""
Used on: Jobs
The presence of this annotation on a Job used to indicate that the control plane is
tracking the Job status using finalizers.
Adding or removing this annotation no longer has an effect (Kubernetes v1.27 and later)
All Jobs are tracked with finalizers.
job-name (deprecated)
Type: Label
Example: job-name: "pi"
Used on: Jobs and Pods controlled by Jobs
Note:
Starting from Kubernetes 1.27, this label is deprecated.
Kubernetes 1.27 and newer ignore this label and use the prefixed job-name label.
controller-uid (deprecated)
Type: Label
Example: controller-uid: "$UID"
Used on: Jobs and Pods controlled by Jobs
Note:
Starting from Kubernetes 1.27, this label is deprecated.
Kubernetes 1.27 and newer ignore this label and use the prefixed controller-uid label.
batch.kubernetes.io/job-name
Type: Label
Example: batch.kubernetes.io/job-name: "pi"
Used on: Jobs and Pods controlled by Jobs
This label is used as a user-friendly way to get Pods corresponding to a Job.
The job-name comes from the name of the Job and allows for an easy way to
get Pods corresponding to the Job.
This label is used as a programmatic way to get all Pods corresponding to a Job. The controller-uid is a unique identifier that gets set in the selector field so the Job
controller can get all the corresponding Pods.
This annotation requires the PodTolerationRestriction
admission controller to be enabled. This annotation key allows assigning tolerations to a
namespace and any new pods created in this namespace would get these tolerations added.
This annotation is only useful when the (Alpha)
PodTolerationRestriction
admission controller is enabled. The annotation value is a JSON document that defines a list of
allowed tolerations for the namespace it annotates. When you create a Pod or modify its
tolerations, the API server checks the tolerations to see if they are mentioned in the allow list.
The pod is admitted only if the check succeeds.
The kubelet detects memory pressure based on memory.available and allocatableMemory.available
observed on a Node. The observed values are then compared to the corresponding thresholds that can
be set on the kubelet to determine if the Node condition and taint should be added/removed.
The kubelet detects disk pressure based on imagefs.available, imagefs.inodesFree,
nodefs.available and nodefs.inodesFree(Linux only) observed on a Node.
The observed values are then compared to the corresponding thresholds that can be set on the
kubelet to determine if the Node condition and taint should be added/removed.
This is initially set by the kubelet when the cloud provider used indicates a requirement for
additional network configuration. Only when the route on the cloud is configured properly will the
taint be removed by the cloud provider.
The kubelet checks D-value of the size of /proc/sys/kernel/pid_max and the PIDs consumed by
Kubernetes on a node to get the number of available PIDs that referred to as the pid.available
metric. The metric is then compared to the corresponding threshold that can be set on the kubelet
to determine if the node condition and taint should be added/removed.
A user can manually add the taint to a Node marking it out-of-service.
If a Node is marked out-of-service with this taint, the Pods on the node
will be forcefully deleted if there are no matching tolerations on it and
volume detach operations for the Pods terminating on the node will happen immediately.
This allows the Pods on the out-of-service node to recover quickly on a different node.
Sets this taint on a Node to mark it as unusable, when kubelet is started with the "external"
cloud provider, until a controller from the cloud-controller-manager initializes this Node, and
then removes the taint.
If a Node is in a cloud provider specified shutdown state, the Node gets tainted accordingly
with node.cloudprovider.kubernetes.io/shutdown and the taint effect of NoSchedule.
These labels are used by the Node Feature Discovery (NFD) component to advertise
features on a node. All built-in labels use the feature.node.kubernetes.io label
namespace and have the format feature.node.kubernetes.io/<feature-name>: "true".
NFD has many extension points for creating vendor and application-specific labels.
For details, see the customization guide.
For node(s) where the Node Feature Discovery (NFD)
master
is scheduled, this annotation records the version of the NFD master.
It is used for informative use only.
This annotation records a comma-separated list of node feature labels managed by
Node Feature Discovery (NFD).
NFD uses this for an internal mechanism. You should not edit this annotation yourself.
This annotation records a comma-separated list of
extended resources
managed by Node Feature Discovery (NFD).
NFD uses this for an internal mechanism. You should not edit this annotation yourself.
nfd.node.kubernetes.io/node-name
Type: Label
Example: nfd.node.kubernetes.io/node-name: node-1
Used on: Nodes
It specifies which node the NodeFeature object is targeting.
Creators of NodeFeature objects must set this label and
consumers of the objects are supposed to use the label for
filtering features designated for a certain node.
Note:
These Node Feature Discovery (NFD) labels or annotations only apply to
the nodes where NFD is running. To learn more about NFD and
its components go to its official documentation.
The cloud controller manager integration with AWS elastic load balancing configures
the load balancer for a Service based on this annotation. The value determines
how often the load balancer writes log entries. For example, if you set the value
to 5, the log writes occur 5 seconds apart.
The cloud controller manager integration with AWS elastic load balancing configures
the load balancer for a Service based on this annotation. Access logging is enabled
if you set the annotation to "true".
Example: service.beta.kubernetes.io/aws-load-balancer-access-log-s3-bucket-name: example
Used on: Service
The cloud controller manager integration with AWS elastic load balancing configures
the load balancer for a Service based on this annotation. The load balancer
writes logs to an S3 bucket with the name you specify.
The cloud controller manager integration with AWS elastic load balancing configures
the load balancer for a Service based on this annotation. The load balancer
writes log objects with the prefix that you specify.

tags (an AWS concept) for a load balancer based on the comma-separated key/value
pairs in the value of this annotation.
The cloud controller manager integration with AWS elastic load balancing configures
the load balancer based on this annotation. The load balancer's connection draining
setting depends on the value you set.
If you configure connection draining
for a Service of type: LoadBalancer, and you use the AWS cloud, the integration configures
the draining period based on this annotation. The value you set determines the draining
timeout in seconds.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. The load balancer has a configured idle
timeout period (in seconds) that applies to its connections. If no data has been
sent or received by the time that the idle timeout period elapses, the load balancer
closes the connection.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. If you set this annotation to "true",
each load balancer node distributes requests evenly across the registered targets
in all enabled availability zones.
If you disable cross-zone load balancing, each load balancer node distributes requests
evenly across the registered targets in its availability zone only.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. The value is a comma-separated list
of elastic IP address allocation IDs.
This annotation is only relevant for Services of type: LoadBalancer, where
the load balancer is an AWS Network Load Balancer.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. The annotation value is a comma-separated
list of extra AWS VPC security groups to configure for the load balancer.

of seconds before a probe that hasn't yet succeeded is automatically treated as
having failed.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. The annotation value specifies the number of
successive unsuccessful health checks required for a backend to be considered unhealthy
for traffic.
The cloud controller manager integration with AWS elastic load balancing configures
a load balancer based on this annotation. When you set this annotation to "true",
the integration configures an internal load balancer.
If you set this annotation on a Service, and you also annotate that Service with
service.beta.kubernetes.io/aws-load-balancer-type: "external", and you use the
AWS load balancer controller
in your cluster, then the AWS load balancer controller sets the name of that load
balancer to the value you set for this annotation.
See annotations
in the AWS load balancer controller documentation.
The official Kubernetes integration with AWS elastic load balancing configures
a load balancer based on this annotation. The only permitted value is "*",
which indicates that the load balancer should wrap TCP connections to the backend
Pod with the PROXY protocol.
The AWS load balancer controller uses this annotation to specify a comma separated list
of security groups you want to attach to an AWS load balancer. Both name and ID of security
are supported where name matches a Name tag, not the groupName attribute.
When this annotation is added to a Service, the load-balancer controller attaches the security groups
referenced by the annotation to the load balancer. If you omit this annotation, the AWS load balancer
controller automatically creates a new security group and attaches it to the load balancer.
Note:
Kubernetes v1.27 and later do not directly set or read this annotation. However, the AWS
load balancer controller (part of the Kubernetes project) does still use the
service.beta.kubernetes.io/aws-load-balancer-security-groups annotation.
The official integration with AWS elastic load balancing configures TLS for a Service of
type: LoadBalancer based on this annotation. The value of the annotation is the
AWS Resource Name (ARN) of the X.509 certificate that the load balancer listener should
use.
(The TLS protocol is based on an older technology that abbreviates to SSL.)
The official integration with AWS elastic load balancing configures TLS for a Service of
type: LoadBalancer based on this annotation. The value of the annotation is the name
of an AWS policy for negotiating TLS with a client peer.
The official integration with AWS elastic load balancing configures TLS for a Service of
type: LoadBalancer based on this annotation. The value of the annotation is either "*",
which means that all the load balancer's ports should use TLS, or it is a comma separated
list of port numbers.
Kubernetes' official integration with AWS uses this annotation to configure a
load balancer and determine in which AWS availability zones to deploy the managed
load balancing service. The value is either a comma separated list of subnet names, or a
comma separated list of subnet IDs.
Kubernetes' official integration with AWS uses this annotation to determine which
nodes in your cluster should be considered as valid targets for the load balancer.
Kubernetes' official integrations with AWS use this annotation to determine
whether the AWS cloud provider integration should manage a Service of
type: LoadBalancer.
There are two permitted values:
nlb
the cloud controller manager configures a Network Load Balancer
external
the cloud controller manager does not configure any load balancer
If you deploy a Service of type: LoadBalancer on AWS, and you don't set any
service.beta.kubernetes.io/aws-load-balancer-type annotation,
the AWS integration deploys a classic Elastic Load Balancer. This behavior,
with no annotation present, is the default unless you specify otherwise.
When you set this annotation to external on a Service of type: LoadBalancer,
and your cluster has a working deployment of the AWS Load Balancer controller,
then the AWS Load Balancer controller attempts to deploy a load balancer based
on the Service specification.
Caution:
Do not modify or add the service.beta.kubernetes.io/aws-load-balancer-type annotation
on an existing Service object. See the AWS documentation on this topic for more
details.
This annotation only works for Azure standard load balancer backed service.
This annotation is used on the Service to specify whether the load balancer
should disable or enable TCP reset on idle timeout. If enabled, it helps
applications to behave more predictably, to detect the termination of a connection,
remove expired connections and initiate new connections.
You can set the value to be either true or false.
Value must be one of privileged, baseline, or restricted which correspond to
Pod Security Standard levels.
Specifically, the enforce label prohibits the creation of any Pod in the labeled
Namespace which does not meet the requirements outlined in the indicated level.
Value must be latest or a valid Kubernetes version in the format v<major>.<minor>.
This determines the version of the
Pod Security Standard
policies to apply when validating a Pod.
Value must be one of privileged, baseline, or restricted which correspond to
Pod Security Standard levels.
Specifically, the audit label does not prevent the creation of a Pod in the labeled
Namespace which does not meet the requirements outlined in the indicated level,
but adds an this annotation to the Pod.

Specifically, the warn label does not prevent the creation of a Pod in the labeled
Namespace which does not meet the requirements outlined in the indicated level,
but returns a warning to the user after doing so.
Note that warnings are also displayed when creating or updating objects that contain
Pod templates, such as Deployments, Jobs, StatefulSets, etc.
Value must be latest or a valid Kubernetes version in the format v<major>.<minor>.
This determines the version of the Pod Security Standard
policies to apply when validating a submitted Pod.
Note that warnings are also displayed when creating or updating objects that contain
Pod templates, such as Deployments, Jobs, StatefulSets, etc.
Used on: ClusterRole, ClusterRoleBinding, Role, RoleBinding
When this annotation is set to "true" on default RBAC objects created by the API server,
they are automatically updated at server start to add missing permissions and subjects
(extra permissions and subjects are left in place).
To prevent autoupdating a particular role or rolebinding, set this annotation to "false".
If you create your own RBAC objects and set this annotation to "false", kubectl auth reconcile
(which allows reconciling arbitrary RBAC objects in a manifest)
respects this annotation and does not automatically add missing permissions and subjects.
kubernetes.io/psp (deprecated)
Type: Annotation
Example: kubernetes.io/psp: restricted
Used on: Pod
This annotation was only relevant if you were using
PodSecurityPolicy objects.
Kubernetes v1.36 does not support the PodSecurityPolicy API.
When the PodSecurityPolicy admission controller admitted a Pod, the admission controller
modified the Pod to have this annotation.
The value of the annotation was the name of the PodSecurityPolicy that was used for validation.
Kubernetes before v1.25 allowed you to configure seccomp behavior using this annotation.
See Restrict a Container's Syscalls with seccomp to
learn the supported way to specify seccomp restrictions for a Pod.
Kubernetes before v1.25 allowed you to configure seccomp behavior using this annotation.
See Restrict a Container's Syscalls with seccomp to
learn the supported way to specify seccomp restrictions for a Pod.
Value can either be true or false. This determines whether a user can modify
the mode of the source volume when a PersistentVolumeClaim is being created from
a VolumeSnapshot.
This label/annotation is used to store the name of the JobSet that a Job or Pod belongs to.
JobSet is an extension API that you can deploy into your Kubernetes cluster.
This label or annotation stores the name of the replicated job that this Job or Pod is part of.
jobset.sigs.k8s.io/job-index
Type: Label, Annotation
Example: jobset.sigs.k8s.io/job-index: "0"
Used on: Jobs, Pods
This label/annotation is set by the JobSet controller on child Jobs and Pods. It contains the index of the Job replica within its parent ReplicatedJob.
The JobSet controller sets this label (and also an annotation with the same key) on child Jobs and
Pods of a JobSet. The value is the SHA256 hash of the namespaced Job name.
You can set this label/annotation on a JobSet to ensure exclusive Job
placement per topology group. You can also define this label or annotation on a replicated job
template. Read the documentation for JobSet to learn more.
This label/annotation can be applied to a JobSet. When it's set, the JobSet controller modifies the Jobs and their corresponding Pods by adding node selectors and tolerations. This ensures exclusive job placement per topology domain, restricting the scheduling of these Pods to specific nodes based on the strategy.
This label is either set manually or automatically (for example, a cluster autoscaler) on the nodes. When alpha.jobset.sigs.k8s.io/node-selector is set to "true", the JobSet controller adds a nodeSelector to this node label (along with the toleration to the taint alpha.jobset.sigs.k8s.io/no-schedule discussed next).
This taint is either set manually or automatically (for example, a cluster autoscaler) on the nodes. When alpha.jobset.sigs.k8s.io/node-selector is set to "true", the JobSet controller adds a toleration to this node taint (along with the node selector to the label alpha.jobset.sigs.k8s.io/namespaced-job discussed previously).
This annotation/label is used on Jobs and Pods to store a stable network endpoint where the coordinator
pod can be reached if the JobSet spec defines the .spec.coordinator field.
Annotation that kubeadm places on locally managed etcd Pods to keep track of
a list of URLs where etcd clients should connect to.
This is used mainly for etcd cluster health check purposes.
Annotation that kubeadm places on locally managed kube-apiserver Pods to keep track
of the exposed advertise address/port endpoint for that API server instance.
Annotation that kubeadm places on ConfigMaps that it manages for configuring components.
It contains a hash (SHA-256) used to determine if the user has applied settings different
from the kubeadm defaults for a particular component.
node-role.kubernetes.io/control-plane
Type: Label
Used on: Node
A marker label to indicate that the node is used to run control plane components.
The kubeadm tool applies this label to the control plane nodes that it manages.
Other cluster management tools typically also set this taint.
You can label control plane nodes with this label to make it easier to schedule Pods
only onto these nodes, or to avoid running Pods on the control plane.
If this label is set, the EndpointSlice controller
ignores that node while calculating Topology Aware Hints.
node-role.kubernetes.io/*
Type: Label
Example: node-role.kubernetes.io/gpu: gpu
Used on: Node
This optional label is applied to a node when you want to mark a node role.
The node role (text following / in the label key) can be set, as long as the overall key follows the
syntax rules for
object labels.
Taint that kubeadm applies on control plane nodes to restrict placing Pods and
allow only specific pods to schedule on them.
If this Taint is applied, control plane nodes allow only critical workloads to
be scheduled onto them. You can manually remove this taint with the following
command on a specific node.
Taint that kubeadm previously applied on control plane nodes to allow only critical
workloads to schedule on them. Replaced by the
node-role.kubernetes.io/control-plane
taint. kubeadm no longer sets or uses this deprecated taint.
Used to grant administrative access to certain resource.k8s.io API types within
a namespace. When this label is set on a namespace with the value "true"
(case-sensitive), it allows the use of adminAccess: true in any namespaced
resource.k8s.io API types. Currently, this permission applies to
ResourceClaim and ResourceClaimTemplate objects.
This page serves as a reference for the audit annotations of the kubernetes.io
namespace. These annotations apply to Event object from API group
audit.k8s.io.
Note:
The following annotations are not used within the Kubernetes API. When you
enable auditing in your cluster,
audit event data is written using Event from API group audit.k8s.io.
The annotations apply to audit events. Audit events are different from objects in the
Event API (API group
events.k8s.io).
k8s.io/deprecated
Example: k8s.io/deprecated: "true"
Value must be "true" or "false". The value "true" indicates that the
request used a deprecated API version.
k8s.io/removed-release
Example: k8s.io/removed-release: "1.22"
Value must be in the format "<MAJOR>.<MINOR>". It is set to target the removal release
on requests made to deprecated API versions with a target removal release.
Value must be one of user, namespace, or runtimeClass which correspond to
Pod Security Exemption
dimensions. This annotation indicates on which dimension was based the exemption
from the PodSecurity enforcement.
Value must be privileged:<version>, baseline:<version>,
restricted:<version> which correspond to Pod Security
Standard levels accompanied by
a version which must be latest or a valid Kubernetes version in the format
v<MAJOR>.<MINOR>. This annotations informs about the enforcement level that
allowed or denied the pod during PodSecurity admission.
Example: pod-security.kubernetes.io/audit-violations: would violate PodSecurity "restricted:latest": allowPrivilegeEscalation != false (container "example" must set securityContext.allowPrivilegeEscalation=false), ...
Value details an audit policy violation, it contains the
Pod Security Standard level
that was transgressed as well as the specific policies on the fields that were
violated from the PodSecurity enforcement.
Value is always "true". This annotation indicates that the audit event has been truncated
because the event size exceeded the configured maximum. Truncation is disabled by default
and must be explicitly enabled via the API server flags.
This annotation indicates the measure of latency incurred inside the storage layer,
it accounts for the time it takes to send data to the etcd and get the complete response back.
The value of this audit annotation does not include the time incurred in admission, or validation.
Example: missing-san.invalid-cert.kubernetes.io/example-svc.example-namespace.svc: "relies on a legacy Common Name field instead of the SAN extension for subject validation"
Used by Kubernetes version v1.24 and later
This annotation indicates a webhook or aggregated API server
is using an invalid certificate that is missing subjectAltNames.
Support for these certificates was disabled by default in Kubernetes 1.19,
and removed in Kubernetes 1.23.
Requests to endpoints using these certificates will fail.
Services using these certificates should replace them as soon as possible
to avoid disruption when running in Kubernetes 1.23+ environments.
Example: insecure-sha1.invalid-cert.kubernetes.io/example-svc.example-namespace.svc: "uses an insecure SHA-1 signature"
Used by Kubernetes version v1.24 and later
This annotation indicates a webhook or aggregated API server
is using an insecure certificate signed with a SHA-1 hash.
Support for these insecure certificates is disabled by default in Kubernetes 1.24,
and will be removed in a future release.
Services using these certificates should replace them as soon as possible,
to ensure connections are secured properly and to avoid disruption in future releases.
This annotation indicates that a admission policy validation evaluated to false
for an API request, or that the validation resulted in an error while the policy
was configured with failurePolicy: Fail.
The value of the annotation is a JSON object. The message in the JSON
provides the message about the validation failure.
The policy, binding and expressionIndex in the JSON identifies the
name of the ValidatingAdmissionPolicy, the name of the
ValidatingAdmissionPolicyBinding and the index in the policy validations of
the CEL expressions that failed, respectively.
The validationActions shows what actions were taken for this validation failure.
See Validating Admission Policy
for more details about validationActions.
5 - Kubernetes API
Kubernetes' API is the application that serves Kubernetes functionality through a RESTful interface and stores the state of the cluster.
Kubernetes resources and "records of intent" are all stored as API objects, and modified via RESTful calls to the API. The API allows configuration to be managed in a declarative way. Users can interact with the Kubernetes API directly, or via tools like kubectl. The core Kubernetes API is flexible and can also be extended to support custom resources.

5.2 - Admissionregistration
5.2.1 - MutatingAdmissionPolicy
MutatingAdmissionPolicy describes the definition of an admission mutation policy that mutates the object coming into admission chain.
apiVersion: admissionregistration.k8s.io/v1
import "k8s.io/api/admissionregistration/v1"
MutatingAdmissionPolicy
MutatingAdmissionPolicy describes the definition of an admission mutation policy that mutates the object coming into admission chain.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec defines the desired behavior of the MutatingAdmissionPolicy.
MutatingAdmissionPolicySpec
MutatingAdmissionPolicySpec defines the desired behavior of the admission policy.
Field
Description
failurePolicy string
failurePolicy defines how to handle failures for the admission policy. Failures can occur from CEL expression parse errors, type check errors, runtime errors and invalid or mis-configured policy definitions or bindings. A policy is invalid if paramKind refers to a non-existent Kind. A binding is invalid if paramRef.name refers to a non-existent resource. failurePolicy does not define how validations that evaluate to false are handled. Allowed values are Ignore or Fail. Defaults to Fail.
Possible enum values: - `"Fail"` means that an error calling the webhook causes the admission to fail. - `"Ignore"` means that an error calling the webhook is ignored.
matchConditions is a list of conditions that must be met for a request to be validated. Match conditions filter requests that have already been matched by the matchConstraints. An empty list of matchConditions matches all requests. There are a maximum of 64 match conditions allowed. If a parameter object is provided, it can be accessed via the `params` handle in the same manner as validation expressions. The exact matching logic is (in order): 1. If ANY matchCondition evaluates to FALSE, the policy is skipped. 2. If ALL matchConditions evaluate to TRUE, the policy is evaluated. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the policy is skipped
matchConstraints specifies what resources this policy is designed to validate. The MutatingAdmissionPolicy cares about a request if it matches _all_ Constraints. However, in order to prevent clusters from being put into an unstable state that cannot be recovered from via the API MutatingAdmissionPolicy cannot match MutatingAdmissionPolicy and MutatingAdmissionPolicyBinding. The CREATE, UPDATE and CONNECT operations are allowed. The DELETE operation may not be matched. '\*' matches CREATE, UPDATE and CONNECT. Required.
mutations contain operations to perform on matching objects. mutations may not be empty; a minimum of one mutation is required. mutations are evaluated in order, and are reinvoked according to the reinvocationPolicy. The mutations of a policy are invoked for each binding of this policy and reinvocation of mutations occurs on a per binding basis.
paramKind specifies the kind of resources used to parameterize this policy. If absent, there are no parameters for this policy and the param CEL variable will not be provided to validation expressions. If paramKind refers to a non-existent kind, this policy definition is mis-configured and the FailurePolicy is applied. If paramKind is specified but paramRef is unset in MutatingAdmissionPolicyBinding, the params variable will be null.
reinvocationPolicy string
reinvocationPolicy indicates whether mutations may be called multiple times per MutatingAdmissionPolicyBinding as part of a single admission evaluation. Allowed values are "Never" and "IfNeeded". Never: These mutations will not be called more than once per binding in a single admission evaluation. IfNeeded: These mutations may be invoked more than once per binding for a single admission request and there is no guarantee of order with respect to other admission plugins, admission webhooks, bindings of this policy and admission policies. Mutations are only reinvoked when mutations change the object after this mutation is invoked. Required.
Possible enum values: - `"IfNeeded"` indicates that the mutation may be called at least one additional time as part of the admission evaluation if the object being admitted is modified by other admission plugins after the initial mutation call. - `"Never"` indicates that the mutation must not be called more than once in a single admission evaluation.
variables contain definitions of variables that can be used in composition of other expressions. Each variable is defined as a named CEL expression. The variables defined here will be available under `variables` in other expressions of the policy except matchConditions because matchConditions are evaluated before the rest of the policy. The expression of a variable can refer to other variables defined earlier in the list but not those after. Thus, variables must be sorted by the order of first appearance and acyclic.
MutatingAdmissionPolicyList
MutatingAdmissionPolicyList is a list of MutatingAdmissionPolicy.

ApplyConfiguration
ApplyConfiguration defines the desired configuration values of an object.
Field
Description
expression string
expression will be evaluated by CEL to create an apply configuration. ref: https://github.com/google/cel-spec Apply configurations are declared in CEL using object initialization. For example, this CEL expression returns an apply configuration to set a single field: Object{ spec: Object.spec{ serviceAccountName: "example" } } Apply configurations may not modify atomic structs, maps or arrays due to the risk of accidental deletion of values not included in the apply configuration. CEL expressions have access to the object types needed to create apply configurations: - 'Object' - CEL type of the resource object. - 'Object.\' - CEL type of object field (such as 'Object.spec') - 'Object.\.\...\` - CEL type of nested field (such as 'Object.spec.containers') CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables: - 'object' - The object from the incoming request.

The value is null for CREATE requests. - 'request' - Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)). - 'params' - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind. - 'namespaceObject' - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources. - 'variables' - Map of composited variables, from its name to its lazily evaluated value. For example, a variable named 'foo' can be accessed as 'variables.foo'. - 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request. See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz - 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the request resource. The `apiVersion`, `kind`, `metadata.name` and `metadata.generateName` are always accessible from the root of the object. No other metadata properties are accessible. Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Required.
JSONPatch
JSONPatch defines a JSON Patch.
Field
Description
expression string
expression will be evaluated by CEL to create a [JSON patch](https://jsonpatch.com/). ref: https://github.com/google/cel-spec expression must return an array of JSONPatch values. For example, this CEL expression returns a JSON patch to conditionally modify a value: [ JSONPatch{op: "test", path: "/spec/example", value: "Red"}, JSONPatch{op: "replace", path: "/spec/example", value: "Green"} ] To define an object for the patch value, use Object types. For example: [ JSONPatch{ op: "add", path: "/spec/selector", value: Object.spec.selector{matchLabels: {"environment": "test"}} } ] To use strings containing '/' and '~' as JSONPatch path keys, use "jsonpatch.escapeKey". For example: [ JSONPatch{ op: "add", path: "/metadata/labels/" + jsonpatch.escapeKey("example.com/environment"), value: "test" }, ] CEL expressions have access to the types needed to create JSON patches and objects: - 'JSONPatch' - CEL type of JSON Patch operations. JSONPatch has the fields 'op', 'from', 'path' and 'value'. See [JSON patch](https://jsonpatch.com/) for more details. The 'value' field may be set to any of: string, integer, array, map or object. If set, the 'path' and 'from' fields must be set to a [JSON pointer](https://datatracker.ietf.org/doc/html/rfc6901/) string, where the 'jsonpatch.escapeKey()' CEL function may be used to escape path keys containing '/' and '~'. - 'Object' - CEL type of the resource object. - 'Object.\' - CEL type of object field (such as 'Object.spec') - 'Object.\.\...\` - CEL type of nested field (such as 'Object.spec.containers') CEL expressions have access to the contents of the API request, organized into CEL variables as well as some other useful variables: - 'object' - The object from the incoming request. The value is null for DELETE requests. - 'oldObject' - The existing object. The value is null for CREATE requests. - 'request' - Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)). - 'params' - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind. - 'namespaceObject' - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources. - 'variables' - Map of composited variables, from its name to its lazily evaluated value. For example, a variable named 'foo' can be accessed as 'variables.foo'. - 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request. See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz - 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the request resource. CEL expressions have access to [Kubernetes CEL function libraries](https://kubernetes.io/docs/reference/using-api/cel/#cel-options-language-features-and-libraries) as well as: - 'jsonpatch.escapeKey' - Performs JSONPatch key escaping. '~' and '/' are escaped as '~0' and `~1' respectively). Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Required.
Mutation
Mutation specifies the CEL expression which is used to apply the Mutation.
applyConfiguration defines the desired configuration values of an object. The configuration is applied to the admission object using [structured merge diff](https://github.com/kubernetes-sigs/structured-merge-diff). A CEL expression is used to create apply configuration.
jsonPatch defines a [JSON patch](https://jsonpatch.com/) operation to perform a mutation to the object. A CEL expression is used to create the JSON patch.
patchType* string
patchType indicates the patch strategy used. Allowed values are "ApplyConfiguration" and "JSONPatch". Required.
Possible enum values: - `"ApplyConfiguration"` ApplyConfiguration indicates that the mutation is using apply configuration to mutate the object. - `"JSONPatch"` JSONPatch indicates that the object is mutated through JSON Patch.

dryRun
string

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
GET /apis/admissionregistration.k8s.io/v1/watch/mutatingadmissionpolicies
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection.

The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
MutatingAdmissionPolicyBinding binds the MutatingAdmissionPolicy with parametrized resources. MutatingAdmissionPolicyBinding and the optional parameter resource together define how cluster administrators configure policies for clusters.
For a given admission request, each binding will cause its policy to be evaluated N times, where N is 1 for policies/bindings that don't use params, otherwise N is the number of parameters selected by the binding. Each evaluation is constrained by a runtime cost budget.
Adding/removing policies, bindings, or params can not affect whether a given (policy, binding, param) combination is within its own CEL budget.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
matchResources limits what resources match this binding and may be mutated by it. Note that if matchResources matches a resource, the resource must also match a policy's matchConstraints and matchConditions before the resource may be mutated. When matchResources is unset, it does not constrain resource matching, and only the policy's matchConstraints and matchConditions must match for the resource to be mutated. Additionally, matchResources.resourceRules are optional and do not constraint matching when unset. Note that this is differs from MutatingAdmissionPolicy matchConstraints, where resourceRules are required. The CREATE, UPDATE and CONNECT operations are allowed. The DELETE operation may not be matched. '\*' matches CREATE, UPDATE and CONNECT.
paramRef specifies the parameter resource used to configure the admission control policy. It should point to a resource of the type specified in spec.ParamKind of the bound MutatingAdmissionPolicy. If the policy specifies a ParamKind and the resource referred to by ParamRef does not exist, this binding is considered mis-configured and the FailurePolicy of the MutatingAdmissionPolicy applied. If the policy does not specify a ParamKind then this field is ignored, and the rules are evaluated without a param.
policyName string
policyName references a MutatingAdmissionPolicy name which the MutatingAdmissionPolicyBinding binds to. If the referenced resource does not exist, this binding is considered invalid and will be ignored Required.
MutatingAdmissionPolicyBindingList
MutatingAdmissionPolicyBindingList is a list of MutatingAdmissionPolicyBinding.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

MutatingWebhook
MutatingWebhook describes an admission webhook and the resources and operations it applies to.
Field
Description
admissionReviewVersions* string array
admissionReviewVersions is an ordered list of preferred `AdmissionReview` versions the Webhook expects. API server will try to use first version in the list which it supports. If none of the versions specified in this list supported by API server, validation will fail for this object. If a persisted webhook configuration specifies allowed versions and does not include any versions known to the API Server, calls to the webhook will fail and be subject to the failure policy.
clientConfig defines how to communicate with the hook. Required
failurePolicy string
failurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.
Possible enum values: - `"Fail"` means that an error calling the webhook causes the admission to fail. - `"Ignore"` means that an error calling the webhook is ignored.
matchConditions is a list of conditions that must be met for a request to be sent to this webhook. Match conditions filter requests that have already been matched by the rules, namespaceSelector, and objectSelector. An empty list of matchConditions matches all requests. There are a maximum of 64 match conditions allowed. The exact matching logic is (in order): 1. If ANY matchCondition evaluates to FALSE, the webhook is skipped. 2. If ALL matchConditions evaluate to TRUE, the webhook is called. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the error is ignored and the webhook is skipped
matchPolicy string
matchPolicy defines how the "rules" list is used to match incoming requests. Allowed values are "Exact" or "Equivalent". - Exact: match a request only if it exactly matches a specified rule. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, but "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the webhook. - Equivalent: match a request if modifies a resource listed in rules, even via another API group or version. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, and "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would be converted to apps/v1 and sent to the webhook. Defaults to "Equivalent"
Possible enum values: - `"Equivalent"` means requests should be sent to the webhook if they modify a resource listed in rules via another API group or version. - `"Exact"` means requests should only be sent to the webhook if they exactly match a given rule.
name* string
name is the name of the admission webhook. Name should be fully qualified, e.g., imagepolicy.kubernetes.io, where "imagepolicy" is the name of the webhook, and kubernetes.io is the name of the organization. Required.
namespaceSelector decides whether to run the webhook on an object based on whether the namespace for that object matches the selector. If the object itself is a namespace, the matching is performed on object.metadata.labels. If the object is another cluster scoped resource, it never skips the webhook. For example, to run the webhook on any objects whose namespace is not associated with "runlevel" of "0" or "1"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "runlevel", "operator": "NotIn", "values": [ "0", "1" ] } ] } If instead you want to only run the webhook on any objects whose namespace is associated with the "environment" of "prod" or "staging"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "environment", "operator": "In", "values": [ "prod", "staging" ] } ] } See https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/ for more examples of label selectors. Default to the empty LabelSelector, which matches everything.
objectSelector decides whether to run the webhook based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the webhook, and is considered to match if either object matches the selector. A null object (oldObject in the case of create, or newObject in the case of delete) or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object) is not considered to match. Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. Default to the empty LabelSelector, which matches everything.
reinvocationPolicy string
reinvocationPolicy indicates whether this webhook should be called multiple times as part of a single admission evaluation. Allowed values are "Never" and "IfNeeded". Never: the webhook will not be called more than once in a single admission evaluation. IfNeeded: the webhook will be called at least one additional time as part of the admission evaluation if the object being admitted is modified by other admission plugins after the initial webhook call. Webhooks that specify this option *must* be idempotent, able to process objects they previously admitted. Note: * the number of additional invocations is not guaranteed to be exactly one. * if additional invocations result in further modifications to the object, webhooks are not guaranteed to be invoked again. * webhooks that use this option may be reordered to minimize the number of additional invocations. * to validate an object after all mutations are guaranteed complete, use a validating admission webhook instead. Defaults to "Never".
Possible enum values: - `"IfNeeded"` indicates that the mutation may be called at least one additional time as part of the admission evaluation if the object being admitted is modified by other admission plugins after the initial mutation call. - `"Never"` indicates that the mutation must not be called more than once in a single admission evaluation.
rules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches _any_ Rule. However, in order to prevent ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks from putting the cluster in a state which cannot be recovered from without completely disabling the plugin, ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks are never called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects.
sideEffects* string
sideEffects states whether this webhook has side effects. Acceptable values are: None, NoneOnDryRun (webhooks created via v1beta1 may also specify Some or Unknown). Webhooks with side effects MUST implement a reconciliation system, since a request may be rejected by a future step in the admission chain and the side effects therefore need to be undone. Requests with the dryRun attribute will be auto-rejected if they match a webhook with sideEffects == Unknown or Some.
Possible enum values: - `"None"` means that calling the webhook will have no side effects. - `"NoneOnDryRun"` means that calling the webhook will possibly have side effects, but if the request being reviewed has the dry-run attribute, the side effects will be suppressed. - `"Some"` means that calling the webhook will possibly have side effects. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail. - `"Unknown"` means that no information is known about the side effects of calling the webhook. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.
timeoutSeconds integer
timeoutSeconds specifies the timeout for this webhook. After the timeout passes, the webhook call will be ignored or the API call will fail based on the failure policy. The timeout value must be between 1 and 30 seconds. Default to 10 seconds.

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).

force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
ValidatingAdmissionPolicy describes the definition of an admission validation policy that accepts or rejects an object without changing it.
apiVersion: admissionregistration.k8s.io/v1
import "k8s.io/api/admissionregistration/v1"
ValidatingAdmissionPolicy
ValidatingAdmissionPolicy describes the definition of an admission validation policy that accepts or rejects an object without changing it.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
status represents the current status of the ValidatingAdmissionPolicy, including warnings that are useful to determine if the policy behaves in the expected way. Populated by the system. Read-only.
ValidatingAdmissionPolicySpec
ValidatingAdmissionPolicySpec is the specification of the desired behavior of the AdmissionPolicy.
auditAnnotations contains CEL expressions which are used to produce audit annotations for the audit event of the API request. validations and auditAnnotations may not both be empty; a least one of validations or auditAnnotations is required.
failurePolicy string
failurePolicy defines how to handle failures for the admission policy. Failures can occur from CEL expression parse errors, type check errors, runtime errors and invalid or mis-configured policy definitions or bindings. A policy is invalid if spec.paramKind refers to a non-existent Kind. A binding is invalid if spec.paramRef.name refers to a non-existent resource. failurePolicy does not define how validations that evaluate to false are handled. When failurePolicy is set to Fail, ValidatingAdmissionPolicyBinding validationActions define how failures are enforced. Allowed values are Ignore or Fail. Defaults to Fail.
Possible enum values: - `"Fail"` means that an error calling the webhook causes the admission to fail. - `"Ignore"` means that an error calling the webhook is ignored.
matchConditions is a list of conditions that must be met for a request to be validated. Match conditions filter requests that have already been matched by the rules, namespaceSelector, and objectSelector. An empty list of matchConditions matches all requests. There are a maximum of 64 match conditions allowed. If a parameter object is provided, it can be accessed via the `params` handle in the same manner as validation expressions. The exact matching logic is (in order): 1. If ANY matchCondition evaluates to FALSE, the policy is skipped. 2. If ALL matchConditions evaluate to TRUE, the policy is evaluated. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the policy is skipped
matchConstraints specifies what resources this policy is designed to validate. The AdmissionPolicy cares about a request if it matches _all_ Constraints. However, in order to prevent clusters from being put into an unstable state that cannot be recovered from via the API ValidatingAdmissionPolicy cannot match ValidatingAdmissionPolicy and ValidatingAdmissionPolicyBinding. Required.
paramKind specifies the kind of resources used to parameterize this policy. If absent, there are no parameters for this policy and the param CEL variable will not be provided to validation expressions. If ParamKind refers to a non-existent kind, this policy definition is mis-configured and the FailurePolicy is applied. If paramKind is specified but paramRef is unset in ValidatingAdmissionPolicyBinding, the params variable will be null.
validations contain CEL expressions which is used to apply the validation. Validations and AuditAnnotations may not both be empty; a minimum of one Validations or AuditAnnotations is required.
variables Variable array patch strategy: merge on key name
variables contain definitions of variables that can be used in composition of other expressions. Each variable is defined as a named CEL expression. The variables defined here will be available under `variables` in other expressions of the policy except MatchConditions because MatchConditions are evaluated before the rest of the policy. The expression of a variable can refer to other variables defined earlier in the list but not those after. Thus, Variables must be sorted by the order of first appearance and acyclic.
ValidatingAdmissionPolicyStatus
ValidatingAdmissionPolicyStatus represents the status of an admission validation policy.
typeChecking contains the results of type checking for each expression. Presence of this field indicates the completion of the type checking.
ValidatingAdmissionPolicyList
ValidatingAdmissionPolicyList is a list of ValidatingAdmissionPolicy.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata is the standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
AuditAnnotation
AuditAnnotation describes how to produce an audit annotation for an API request.
Field
Description
key* string
key specifies the audit annotation key. The audit annotation keys of a ValidatingAdmissionPolicy must be unique. The key must be a qualified name ([A-Za-z0-9][-A-Za-z0-9_.]*) no more than 63 bytes in length. The key is combined with the resource name of the ValidatingAdmissionPolicy to construct an audit annotation key: "{ValidatingAdmissionPolicy name}/{key}". If an admission webhook uses the same resource name as this ValidatingAdmissionPolicy and the same audit annotation key, the annotation key will be identical. In this case, the first annotation written with the key will be included in the audit event and all subsequent annotations with the same key will be discarded. Required.
valueExpression* string
valueExpression represents the expression which is evaluated by CEL to produce an audit annotation value. The expression must evaluate to either a string or null value. If the expression evaluates to a string, the audit annotation is included with the string value. If the expression evaluates to null or empty string the audit annotation will be omitted. The valueExpression may be no longer than 5kb in length. If the result of the valueExpression is more than 10kb in length, it will be truncated to 10kb. If multiple ValidatingAdmissionPolicyBinding resources match an API request, then the valueExpression will be evaluated for each binding. All unique values produced by the valueExpressions will be joined together in a comma-separated list. Required.
ExpressionWarning
ExpressionWarning is a warning information that targets a specific expression.
Field
Description
fieldRef* string
fieldRef is the path to the field that refers to the expression. For example, the reference to the expression of the first item of validations is "spec.validations[0].expression"
warning* string
warning contains the content of type checking information in a human-readable form. Each line of the warning contains the type that the expression is checked against, followed by the type check error from the compiler.
TypeChecking
TypeChecking contains results of type checking the expressions in the ValidatingAdmissionPolicy
expressionWarnings contains the type checking warnings for each expression.
Validation
Validation specifies the CEL expression which is used to apply the validation.
Field
Description
expression* string
expression represents the expression which will be evaluated by CEL. ref: https://github.com/google/cel-spec CEL expressions have access to the contents of the API request/response, organized into CEL variables as well as some other useful variables: - 'object' - The object from the incoming request. The value is null for DELETE requests. - 'oldObject' - The existing object. The value is null for CREATE requests. - 'request' - Attributes of the API request([ref](/pkg/apis/admission/types.go#AdmissionRequest)). - 'params' - Parameter resource referred to by the policy binding being evaluated. Only populated if the policy has a ParamKind. - 'namespaceObject' - The namespace object that the incoming object belongs to. The value is null for cluster-scoped resources. - 'variables' - Map of composited variables, from its name to its lazily evaluated value. For example, a variable named 'foo' can be accessed as 'variables.foo'. - 'authorizer' - A CEL Authorizer. May be used to perform authorization checks for the principal (user or service account) of the request. See https://pkg.go.dev/k8s.io/apiserver/pkg/cel/library#Authz - 'authorizer.requestResource' - A CEL ResourceCheck constructed from the 'authorizer' and configured with the request resource. The `apiVersion`, `kind`, `metadata.name` and `metadata.generateName` are always accessible from the root of the object. No other metadata properties are accessible. Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Accessible property names are escaped according to the following rules when accessed in the expression: - '__' escapes to '__underscores__' - '.' escapes to '__dot__' - '-' escapes to '__dash__' - '/' escapes to '__slash__' - Property names that exactly match a CEL RESERVED keyword escape to '__{keyword}__'. The keywords are: "true", "false", "null", "in", "as", "break", "const", "continue", "else", "for", "function", "if", "import", "let", "loop", "package", "namespace", "return". Examples: - Expression accessing a property named "namespace": {"Expression": "object.__namespace__ > 0"} - Expression accessing a property named "x-prop": {"Expression": "object.x__dash__prop > 0"} - Expression accessing a property named "redact__d": {"Expression": "object.redact__underscores__d > 0"} Equality on arrays with list type of 'set' or 'map' ignores element order, i.e. [1, 2] == [2, 1]. Concatenation on arrays with x-kubernetes-list-type use the semantics of the list type: - 'set': `X + Y` performs a union where the array positions of all elements in `X` are preserved and non-intersecting elements in `Y` are appended, retaining their partial order. - 'map': `X + Y` performs a merge where the array positions of all keys in `X` are preserved but the values are overwritten by values in `Y` when the key sets of `X` and `Y` intersect. Elements in `Y` with non-intersecting keys are appended, retaining their partial order. Required.
message string
message represents the message displayed when validation fails. The message is required if the Expression contains line breaks. The message must not contain line breaks. If unset, the message is "failed rule: {Rule}". e.g. "must be a URL with the host matching spec.host" If the Expression contains line breaks. Message is required. The message must not contain line breaks. If unset, the message is "failed Expression: {Expression}".
messageExpression string
messageExpression declares a CEL expression that evaluates to the validation failure message that is returned when this rule fails. Since messageExpression is used as a failure message, it must evaluate to a string. If both message and messageExpression are present on a validation, then messageExpression will be used if validation fails. If messageExpression results in a runtime error, the runtime error is logged, and the validation failure message is produced as if the messageExpression field were unset. If messageExpression evaluates to an empty string, a string with only spaces, or a string that contains line breaks, then the validation failure message will also be produced as if the messageExpression field were unset, and the fact that messageExpression produced an empty string/string with only spaces/string with line breaks will be logged. messageExpression has access to all the same variables as the `expression` except for 'authorizer' and 'authorizer.requestResource'. Example: "object.x must be less than max ("+string(params.max)+")"
reason string
reason represents a machine-readable description of why this validation failed. If this is the first validation in the list to fail, this reason, as well as the corresponding HTTP response code, are used in the HTTP response to the client. The currently supported reasons are: "Unauthorized", "Forbidden", "Invalid", "RequestEntityTooLarge". If not set, StatusReasonInvalid is used in the response to the client.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid").

timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

ValidatingAdmissionPolicyBinding binds the ValidatingAdmissionPolicy with paramerized resources. ValidatingAdmissionPolicyBinding and parameter CRDs together define how cluster administrators configure policies for clusters.
For a given admission request, each binding will cause its policy to be evaluated N times, where N is 1 for policies/bindings that don't use params, otherwise N is the number of parameters selected by the binding.
The CEL expressions of a policy must have a computed CEL cost below the maximum CEL budget. Each evaluation of the policy is given an independent CEL cost budget. Adding/removing policies, bindings, or params can not affect whether a given (policy, binding, param) combination is within its own CEL budget.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
matchResources declares what resources match this binding and will be validated by it. Note that this is intersected with the policy's matchConstraints, so only requests that are matched by the policy can be selected by this. If this is unset, all resources matched by the policy are validated by this binding When resourceRules is unset, it does not constrain resource matching. If a resource is matched by the other fields of this object, it will be validated. Note that this is differs from ValidatingAdmissionPolicy matchConstraints, where resourceRules are required.
paramRef specifies the parameter resource used to configure the admission control policy. It should point to a resource of the type specified in ParamKind of the bound ValidatingAdmissionPolicy. If the policy specifies a ParamKind and the resource referred to by ParamRef does not exist, this binding is considered mis-configured and the FailurePolicy of the ValidatingAdmissionPolicy applied. If the policy does not specify a ParamKind then this field is ignored, and the rules are evaluated without a param.
policyName* string
policyName references a ValidatingAdmissionPolicy name which the ValidatingAdmissionPolicyBinding binds to. If the referenced resource does not exist, this binding is considered invalid and will be ignored Required.
validationActions* string array
validationActions declares how Validations of the referenced ValidatingAdmissionPolicy are enforced. If a validation evaluates to false it is always enforced according to these actions. Failures defined by the ValidatingAdmissionPolicy's FailurePolicy are enforced according to these actions only if the FailurePolicy is set to Fail, otherwise the failures are ignored. This includes compilation errors, runtime errors and misconfigurations of the policy. validationActions is declared as a set of action values. Order does not matter. validationActions may not contain duplicates of the same action. The supported actions values are: "Deny" specifies that a validation failure results in a denied request. "Warn" specifies that a validation failure is reported to the request client in HTTP Warning headers, with a warning code of 299. Warnings can be sent both for allowed or denied admission responses. "Audit" specifies that a validation failure is included in the published audit event for the request. The audit event will contain a `validation.policy.admission.k8s.io/validation_failure` audit annotation with a value containing the details of the validation failures, formatted as a JSON list of objects, each with the following fields: - message: The validation failure message string - policy: The resource name of the ValidatingAdmissionPolicy - binding: The resource name of the ValidatingAdmissionPolicyBinding - expressionIndex: The index of the failed validations in the ValidatingAdmissionPolicy - validationActions: The enforcement actions enacted for the validation failure Example audit annotation: `"validation.policy.admission.k8s.io/validation_failure": "[{\"message\": \"Invalid value\", {\"policy\": \"policy.example.com\", {\"binding\": \"policybinding.example.com\", {\"expressionIndex\": \"1\", {\"validationActions\": [\"Audit\"]}]"` Clients should expect to handle additional values by ignoring any values not recognized. "Deny" and "Warn" may not be used together since this combination needlessly duplicates the validation failure both in the API response body and the HTTP warning headers. Required.
ValidatingAdmissionPolicyBindingList
ValidatingAdmissionPolicyBindingList is a list of ValidatingAdmissionPolicyBinding.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata is the standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds

dryRun
string

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
GET /apis/admissionregistration.k8s.io/v1/watch/validatingadmissionpolicybindings
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

ValidatingWebhook
ValidatingWebhook describes an admission webhook and the resources and operations it applies to.
Field
Description
admissionReviewVersions* string array
admissionReviewVersions is an ordered list of preferred `AdmissionReview` versions the Webhook expects. API server will try to use first version in the list which it supports. If none of the versions specified in this list supported by API server, validation will fail for this object. If a persisted webhook configuration specifies allowed versions and does not include any versions known to the API Server, calls to the webhook will fail and be subject to the failure policy.
clientConfig defines how to communicate with the hook. Required
failurePolicy string
failurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.
Possible enum values: - `"Fail"` means that an error calling the webhook causes the admission to fail. - `"Ignore"` means that an error calling the webhook is ignored.
matchConditions is a list of conditions that must be met for a request to be sent to this webhook. Match conditions filter requests that have already been matched by the rules, namespaceSelector, and objectSelector. An empty list of matchConditions matches all requests. There are a maximum of 64 match conditions allowed. The exact matching logic is (in order): 1. If ANY matchCondition evaluates to FALSE, the webhook is skipped. 2. If ALL matchConditions evaluate to TRUE, the webhook is called. 3. If any matchCondition evaluates to an error (but none are FALSE): - If failurePolicy=Fail, reject the request - If failurePolicy=Ignore, the error is ignored and the webhook is skipped
matchPolicy string
matchPolicy defines how the "rules" list is used to match incoming requests. Allowed values are "Exact" or "Equivalent". - Exact: match a request only if it exactly matches a specified rule. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, but "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would not be sent to the webhook. - Equivalent: match a request if modifies a resource listed in rules, even via another API group or version. For example, if deployments can be modified via apps/v1, apps/v1beta1, and extensions/v1beta1, and "rules" only included `apiGroups:["apps"], apiVersions:["v1"], resources: ["deployments"]`, a request to apps/v1beta1 or extensions/v1beta1 would be converted to apps/v1 and sent to the webhook. Defaults to "Equivalent"
Possible enum values: - `"Equivalent"` means requests should be sent to the webhook if they modify a resource listed in rules via another API group or version. - `"Exact"` means requests should only be sent to the webhook if they exactly match a given rule.
name* string
name is the name of the admission webhook. Name should be fully qualified, e.g., imagepolicy.kubernetes.io, where "imagepolicy" is the name of the webhook, and kubernetes.io is the name of the organization. Required.
namespaceSelector decides whether to run the webhook on an object based on whether the namespace for that object matches the selector. If the object itself is a namespace, the matching is performed on object.metadata.labels. If the object is another cluster scoped resource, it never skips the webhook. For example, to run the webhook on any objects whose namespace is not associated with "runlevel" of "0" or "1"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "runlevel", "operator": "NotIn", "values": [ "0", "1" ] } ] } If instead you want to only run the webhook on any objects whose namespace is associated with the "environment" of "prod" or "staging"; you will set the selector as follows: "namespaceSelector": { "matchExpressions": [ { "key": "environment", "operator": "In", "values": [ "prod", "staging" ] } ] } See https://kubernetes.io/docs/concepts/overview/working-with-objects/labels for more examples of label selectors. Default to the empty LabelSelector, which matches everything.
objectSelector decides whether to run the webhook based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the webhook, and is considered to match if either object matches the selector. A null object (oldObject in the case of create, or newObject in the case of delete) or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object) is not considered to match. Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. Default to the empty LabelSelector, which matches everything.
rules describes what operations on what resources/subresources the webhook cares about. The webhook cares about an operation if it matches _any_ Rule. However, in order to prevent ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks from putting the cluster in a state which cannot be recovered from without completely disabling the plugin, ValidatingAdmissionWebhooks and MutatingAdmissionWebhooks are never called on admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects.
sideEffects* string
sideEffects states whether this webhook has side effects. Acceptable values are: None, NoneOnDryRun (webhooks created via v1beta1 may also specify Some or Unknown). Webhooks with side effects MUST implement a reconciliation system, since a request may be rejected by a future step in the admission chain and the side effects therefore need to be undone. Requests with the dryRun attribute will be auto-rejected if they match a webhook with sideEffects == Unknown or Some.
Possible enum values: - `"None"` means that calling the webhook will have no side effects. - `"NoneOnDryRun"` means that calling the webhook will possibly have side effects, but if the request being reviewed has the dry-run attribute, the side effects will be suppressed. - `"Some"` means that calling the webhook will possibly have side effects. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail. - `"Unknown"` means that no information is known about the side effects of calling the webhook. If a request with the dry-run attribute would trigger a call to this webhook, the request will instead fail.
timeoutSeconds integer
timeoutSeconds specifies the timeout for this webhook. After the timeout passes, the webhook call will be ignored or the API call will fail based on the failure policy. The timeout value must be between 1 and 30 seconds. Default to 10 seconds.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set.

Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
conversion defines conversion settings for the CRD.
group* string

names specify the resource and kind names for the custom resource.
preserveUnknownFields boolean
preserveUnknownFields indicates that object fields which are not specified in the OpenAPI schema should be preserved when persisting to storage. apiVersion, kind, metadata and known fields inside metadata are always preserved. This field is deprecated in favor of setting `x-preserve-unknown-fields` to true in `spec.versions[*].schema.openAPIV3Schema`. See https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions/#field-pruning for details.
scope* string
scope indicates whether the defined custom resource is cluster- or namespace-scoped. Allowed values are `Cluster` and `Namespaced`.
versions is the list of all API versions of the defined custom resource. Version names are used to compute the order in which served versions are listed in API discovery. If the version string is "kube-like", it will sort above non "kube-like" version strings, which are ordered lexicographically. "Kube-like" versions start with a "v", then are followed by a number (the major version), then optionally the string "alpha" or "beta" and another number (the minor version). These are sorted first by GA > beta > alpha (where GA is a version with no suffix such as beta or alpha), and then by comparing major version, then minor version. An example sorted list of versions: v10, v2, v1, v11beta2, v10beta3, v3beta1, v12alpha1, v11alpha2, foo1, foo10.
CustomResourceDefinitionStatus
CustomResourceDefinitionStatus indicates the state of the CustomResourceDefinition
conditions indicate state for particular aspects of a CustomResourceDefinition
observedGeneration integer
The generation observed by the CRD controller.
storedVersions string array
storedVersions lists all versions of CustomResources that were ever persisted. Tracking these versions allows a migration path for stored versions in etcd. The field is mutable so a migration controller can finish a migration to another version (ensuring no old objects are left in storage), and then remove the rest of the versions from this list. Versions may not be removed from `spec.versions` while they exist in this list.
CustomResourceDefinitionList
CustomResourceDefinitionList is a list of CustomResourceDefinition objects.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
items list individual CustomResourceDefinition objects
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Standard object's metadata More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

format string
format is an optional OpenAPI type definition for this column. The 'name' format is applied to the primary identifier column to assist in clients identifying column is the resource name. See https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types for details.
jsonPath* string
jsonPath is a simple JSON path (i.e. with array notation) which is evaluated against each custom resource to produce the value for this column.
name* string
name is a human readable name for the column.
priority integer
priority is an integer defining the relative importance of this column compared to others. Lower numbers are considered higher priority. Columns that may be omitted in limited space scenarios should be given a priority greater than 0.
type* string
type is an OpenAPI type definition for this column. See https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#data-types for details.
CustomResourceConversion
CustomResourceConversion describes how to convert different versions of a CR.
Field
Description
strategy* string
strategy specifies how custom resources are converted between versions. Allowed values are: - `"None"`: The converter only change the apiVersion and would not touch any other field in the custom resource. - `"Webhook"`: API Server will call to an external webhook to do the conversion. Additional information is needed for this option. This requires spec.preserveUnknownFields to be false, and spec.conversion.webhook to be set.
lastTransitionTime last time the condition transitioned from one status to another.
message string
message is a human-readable message indicating details about last transition.
observedGeneration integer
observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance.
reason string
reason is a unique, one-word, CamelCase reason for the condition's last transition.

kind* string
kind is the serialized kind of the resource. It is normally CamelCase and singular. Custom resource instances will use this value as the `kind` attribute in API calls.
listKind string
listKind is the serialized kind of the list for this resource. Defaults to "`kind`List".
plural* string
plural is the plural name of the resource to serve. The custom resources are served under `/apis/\/\/.../\`. Must match the name of the CustomResourceDefinition (in the form `\.\`). Must be all lowercase.

CustomResourceDefinitionVersion
CustomResourceDefinitionVersion describes a version for CRD.
additionalPrinterColumns specifies additional columns returned in Table output. See https://kubernetes.io/docs/reference/using-api/api-concepts/#receiving-resources-as-tables for details. If no columns are specified, a single column displaying the age of the custom resource is used.
deprecated boolean
deprecated indicates this version of the custom resource API is deprecated. When set to true, API requests to this version receive a warning header in the server response. Defaults to false.
deprecationWarning string
deprecationWarning overrides the default warning returned to API clients. May only be set when `deprecated` is true. The default warning indicates this version is deprecated and recommends use of the newest served version of equal or greater stability, if one exists.
name* string
name is the version name, e.g. “v1”, “v2beta1”, etc. The custom resources are served under this version at `/apis/\/\/...` if `served` is true.
selectableFields specifies paths to fields that may be used as field selectors. A maximum of 8 selectable fields are allowed. See https://kubernetes.io/docs/concepts/overview/working-with-objects/field-selectors
served* boolean
served is a flag enabling/disabling this version from being served via REST APIs
storage* boolean
storage indicates this version should be used when persisting custom resources to storage. There must be exactly one version with storage=true.
subresources specify what subresources this version of the defined custom resource have.
CustomResourceSubresourceScale
CustomResourceSubresourceScale defines how to serve the scale subresource for CustomResources.
Field
Description
labelSelectorPath string
labelSelectorPath defines the JSON path inside of a custom resource that corresponds to Scale `status.selector`. Only JSON paths without the array notation are allowed. Must be a JSON Path under `.status` or `.spec`. Must be set to work with HorizontalPodAutoscaler. The field pointed by this JSON path must be a string field (not a complex selector struct) which contains a serialized label selector in string form. More info: https://kubernetes.io/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definitions#scale-subresource If there is no value under the given path in the custom resource, the `status.selector` value in the `/scale` subresource will default to the empty string.
specReplicasPath* string
specReplicasPath defines the JSON path inside of a custom resource that corresponds to Scale `spec.replicas`. Only JSON paths without the array notation are allowed. Must be a JSON Path under `.spec`. If there is no value under the given path in the custom resource, the `/scale` subresource will return an error on GET.
statusReplicasPath* string
statusReplicasPath defines the JSON path inside of a custom resource that corresponds to Scale `status.replicas`. Only JSON paths without the array notation are allowed. Must be a JSON Path under `.status`. If there is no value under the given path in the custom resource, the `status.replicas` value in the `/scale` subresource will default to 0.
CustomResourceSubresourceStatus
CustomResourceSubresourceStatus defines how to serve the status subresource for CustomResources. Status is represented by the .status JSON path inside of a CustomResource. When set, * exposes a /status subresource for the custom resource * PUT requests to the /status subresource take a custom resource object, and ignore changes to anything except the status stanza * PUT/POST/PATCH requests to the custom resource ignore changes to the status stanza
CustomResourceSubresources
CustomResourceSubresources defines the status and scale subresources for CustomResources.
status indicates the custom resource should serve a `/status` subresource. When enabled: 1. requests to the custom resource primary endpoint ignore changes to the `status` stanza of the object. 2. requests to the custom resource `/status` subresource ignore changes to anything other than the `status` stanza of the object.
CustomResourceValidation
CustomResourceValidation is a list of validation methods for CustomResources.
default is a default value for undefined object fields. Defaulting is a beta feature under the CustomResourceDefaulting feature gate. Defaulting requires spec.preserveUnknownFields to be false.

x-kubernetes-embedded-resource defines that the value is an embedded Kubernetes runtime.Object, with TypeMeta and ObjectMeta. The type must be object. It is allowed to further restrict the embedded object. kind, apiVersion and metadata are validated automatically. x-kubernetes-preserve-unknown-fields is allowed to be true, but does not have to be if the object is fully specified (up to kind, apiVersion, metadata).
x-kubernetes-int-or-string boolean
x-kubernetes-int-or-string specifies that this value is either an integer or a string. If this is true, an empty type is allowed and type as child of anyOf is permitted if following one of the following patterns: 1) anyOf: - type: integer - type: string 2) allOf: - anyOf: - type: integer - type: string - ... zero or more
x-kubernetes-list-map-keys string array
x-kubernetes-list-map-keys annotates an array with the x-kubernetes-list-type `map` by specifying the keys used as the index of the map. This tag MUST only be used on lists that have the "x-kubernetes-list-type" extension set to "map". Also, the values specified for this attribute must be a scalar typed field of the child structure (no nesting is supported). The properties specified must either be required or have a default value, to ensure those properties are present for all list items.
x-kubernetes-list-type string
x-kubernetes-list-type annotates an array to further describe its topology. This extension must only be used on lists and may have 3 possible values: 1) `atomic`: the list is treated as a single entity, like a scalar. Atomic lists will be entirely replaced when updated. This extension may be used on any type of list (struct, scalar, ...). 2) `set`: Sets are lists that must not have multiple items with the same value. Each value must be a scalar, an object with x-kubernetes-map-type `atomic` or an array with x-kubernetes-list-type `atomic`. 3) `map`: These lists are like maps in that their elements have a non-index key used to identify them. Order is preserved upon merge. The map tag must only be used on a list with elements of type object. Defaults to atomic for arrays.
x-kubernetes-map-type string
x-kubernetes-map-type annotates an object to further describe its topology. This extension must only be used when type is object and may have 2 possible values: 1) `granular`: These maps are actual maps (key-value pairs) and each fields are independent from each other (they can each be manipulated by separate actors). This is the default behaviour for all maps. 2) `atomic`: the list is treated as a single entity, like a scalar. Atomic maps will be entirely replaced when updated.
x-kubernetes-preserve-unknown-fields boolean
x-kubernetes-preserve-unknown-fields stops the API server decoding step from pruning fields which are not specified in the validation schema. This affects fields recursively, but switches back to normal pruning behaviour if nested properties or additionalProperties are specified in the schema. This can either be true or undefined. False is forbidden.
x-kubernetes-validations describes a list of validation rules written in the CEL expression language.
JSONSchemaPropsOrArray
JSONSchemaPropsOrArray represents a value that can either be a JSONSchemaProps or an array of JSONSchemaProps. Mainly here for serialization purposes.
JSONSchemaPropsOrBool
JSONSchemaPropsOrBool represents JSONSchemaProps or a boolean value. Defaults to true for the boolean property.
SelectableField
SelectableField specifies the JSON path of a field that may be used with field selectors.
Field
Description
jsonPath* string
jsonPath is a simple JSON path which is evaluated against each custom resource to produce a field selector value. Only JSON paths without the array notation are allowed. Must point to a field of type string, boolean or integer. Types with enum values and strings with formats are allowed. If jsonPath refers to absent field in a resource, the jsonPath evaluates to an empty string. Must not point to metdata fields. Required.
ServiceReference
ServiceReference holds a reference to Service.legacy.k8s.io
Field
Description
name* string
name is the name of the service. Required
namespace* string
namespace is the namespace of the service. Required
path string
path is an optional URL path at which the webhook will be contacted.
port integer
port is an optional service port at which the webhook will be contacted. `port` should be a valid port number (1-65535, inclusive). Defaults to 443 for backward compatibility.
ValidationRule
ValidationRule describes a validation rule written in the CEL expression language.
Field
Description
fieldPath string
fieldPath represents the field path returned when the validation fails. It must be a relative JSON path (i.e. with array notation) scoped to the location of this x-kubernetes-validations extension in the schema and refer to an existing field. e.g. when validation checks if a specific attribute `foo` under a map `testMap`, the fieldPath could be set to `.testMap.foo` If the validation checks two lists must have unique attributes, the fieldPath could be set to either of the list: e.g. `.testList` It does not support list numeric index. It supports child operation to refer to an existing field currently. Refer to [JSONPath support in Kubernetes](https://kubernetes.io/docs/reference/kubectl/jsonpath/) for more info. Numeric index of array is not supported. For field name which contains special characters, use `['specialName']` to refer the field name. e.g. for attribute `foo.34$` appears in a list `testList`, the fieldPath could be set to `.testList['foo.34$']`
message string
Message represents the message displayed when validation fails. The message is required if the Rule contains line breaks. The message must not contain line breaks. If unset, the message is "failed rule: {Rule}". e.g. "must be a URL with the host matching spec.host"
messageExpression string
MessageExpression declares a CEL expression that evaluates to the validation failure message that is returned when this rule fails. Since messageExpression is used as a failure message, it must evaluate to a string. If both message and messageExpression are present on a rule, then messageExpression will be used if validation fails. If messageExpression results in a runtime error, the runtime error is logged, and the validation failure message is produced as if the messageExpression field were unset. If messageExpression evaluates to an empty string, a string with only spaces, or a string that contains line breaks, then the validation failure message will also be produced as if the messageExpression field were unset, and the fact that messageExpression produced an empty string/string with only spaces/string with line breaks will be logged. messageExpression has access to all the same variables as the rule; the only difference is the return type. Example: "x must be less than max ("+string(self.max)+")"
optionalOldSelf boolean
optionalOldSelf is used to opt a transition rule into evaluation even when the object is first created, or if the old object is missing the value. When enabled `oldSelf` will be a CEL optional whose value will be `None` if there is no old value, or when the object is initially created. You may check for presence of oldSelf using `oldSelf.hasValue()` and unwrap it after checking using `oldSelf.value()`. Check the CEL documentation for Optional types for more information: https://pkg.go.dev/github.com/google/cel-go/cel#OptionalTypes May not be set unless `oldSelf` is used in `rule`.
reason string
reason provides a machine-readable validation failure reason that is returned to the caller when a request fails this validation rule. The HTTP status code returned to the caller will match the reason of the reason of the first failed validation rule. The currently supported reasons are: "FieldValueInvalid", "FieldValueForbidden", "FieldValueRequired", "FieldValueDuplicate". If not set, default to use "FieldValueInvalid". All future added reasons must be accepted by clients when reading this value and unknown reasons should be treated as FieldValueInvalid.
Possible enum values: - `"FieldValueDuplicate"` is used to report collisions of values that must be unique (e.g. unique IDs). - `"FieldValueForbidden"` is used to report valid (as per formatting rules) values which would be accepted under some conditions, but which are not permitted by the current conditions (such as security policy). - `"FieldValueInvalid"` is used to report malformed values (e.g. failed regex match, too long, out of bounds). - `"FieldValueRequired"` is used to report required values that are not provided (e.g. empty strings, null values, or empty arrays).
rule* string
Rule represents the expression which will be evaluated by CEL. ref: https://github.com/google/cel-spec The Rule is scoped to the location of the x-kubernetes-validations extension in the schema. The `self` variable in the CEL expression is bound to the scoped value. Example: - Rule scoped to the root of a resource with a status subresource: {"rule": "self.status.actual \<= self.spec.maxDesired"} If the Rule is scoped to an object with properties, the accessible properties of the object are field selectable via `self.field` and field presence can be checked via `has(self.field)`. Null valued fields are treated as absent fields in CEL expressions. If the Rule is scoped to an object with additionalProperties (i.e. a map) the value of the map are accessible via `self[mapKey]`, map containment can be checked via `mapKey in self` and all entries of the map are accessible via CEL macros and functions such as `self.all(...)`. If the Rule is scoped to an array, the elements of the array are accessible via `self[i]` and also by macros and functions. If the Rule is scoped to a scalar, `self` is bound to the scalar value. Examples: - Rule scoped to a map of objects: {"rule": "self.components['Widget'].priority \< 10"} - Rule scoped to a list of integers: {"rule": "self.values.all(value, value >= 0 && value \< 100)"} - Rule scoped to a string value: {"rule": "self.startsWith('kube')"} The `apiVersion`, `kind`, `metadata.name` and `metadata.generateName` are always accessible from the root of the object and from any x-kubernetes-embedded-resource annotated objects. No other metadata properties are accessible. Unknown data preserved in custom resources via x-kubernetes-preserve-unknown-fields is not accessible in CEL expressions. This includes: - Unknown field values that are preserved by object schemas with x-kubernetes-preserve-unknown-fields. - Object properties where the property schema is of an "unknown type". An "unknown type" is recursively defined as: - A schema with no type and x-kubernetes-preserve-unknown-fields set to true - An array where the items schema is of an "unknown type" - An object where the additionalProperties schema is of an "unknown type" Only property names of the form `[a-zA-Z_.-/][a-zA-Z0-9_.-/]*` are accessible. Accessible property names are escaped according to the following rules when accessed in the expression: - '__' escapes to '__underscores__' - '.' escapes to '__dot__' - '-' escapes to '__dash__' - '/' escapes to '__slash__' - Property names that exactly match a CEL RESERVED keyword escape to '__{keyword}__'. The keywords are: "true", "false", "null", "in", "as", "break", "const", "continue", "else", "for", "function", "if", "import", "let", "loop", "package", "namespace", "return". Examples: - Rule accessing a property named "namespace": {"rule": "self.__namespace__ > 0"} - Rule accessing a property named "x-prop": {"rule": "self.x__dash__prop > 0"} - Rule accessing a property named "redact__d": {"rule": "self.redact__underscores__d > 0"} Equality on arrays with x-kubernetes-list-type of 'set' or 'map' ignores element order, i.e. [1, 2] == [2, 1]. Concatenation on arrays with x-kubernetes-list-type use the semantics of the list type: - 'set': `X + Y` performs a union where the array positions of all elements in `X` are preserved and non-intersecting elements in `Y` are appended, retaining their partial order. - 'map': `X + Y` performs a merge where the array positions of all keys in `X` are preserved but the values are overwritten by values in `Y` when the key sets of `X` and `Y` intersect. Elements in `Y` with non-intersecting keys are appended, retaining their partial order. If `rule` makes use of the `oldSelf` variable it is implicitly a `transition rule`. By default, the `oldSelf` variable is the same type as `self`. When `optionalOldSelf` is true, the `oldSelf` variable is a CEL optional variable whose value() is the same type as `self`. See the documentation for the `optionalOldSelf` field for details. Transition rules by default are applied only on UPDATE requests and are skipped if an old value could not be found. You can opt a transition rule into unconditional evaluation by setting `optionalOldSelf` to true.
WebhookClientConfig
WebhookClientConfig contains the information to make a TLS connection with the webhook.
Field
Description
caBundle string
caBundle is a PEM encoded CA bundle which will be used to validate the webhook's server certificate. If unspecified, system trust roots on the apiserver are used.
service is a reference to the service for this webhook. Either service or url must be specified. If the webhook is running within the cluster, then you should use `service`.
url string
url gives the location of the webhook, in standard URL form (`scheme://host:port/path`). Exactly one of `url` or `service` must be specified. The `host` should not refer to a service running in the cluster; use the `service` field instead. The host might be resolved via external DNS in some apiservers (e.g., `kube-apiserver` cannot resolve in-cluster DNS as that would be a layering violation). `host` may also be an IP address. Please note that using `localhost` or `127.0.0.1` as a `host` is risky unless you take great care to run this webhook on all hosts which run an apiserver which might need to make calls to this webhook. Such installs are likely to be non-portable, i.e., not easy to turn up in a new cluster. The scheme must be "https"; the URL must begin with "https://". A path is optional, and if present may be any string permissible in a URL. You may use the path to pass an arbitrary string to the webhook, for example, a cluster identifier. Attempting to use a user or basic auth e.g. "user:password@" is not allowed. Fragments ("#...") and query parameters ("?...") are not allowed, either.
WebhookConversion
WebhookConversion describes how to call a conversion webhook
clientConfig is the instructions for how to call the webhook if strategy is `Webhook`.
conversionReviewVersions* string array
conversionReviewVersions is an ordered list of preferred `ConversionReview` versions the Webhook expects. The API server will use the first version in the list which it supports. If none of the versions specified in this list are supported by API server, conversion will fail for the custom resource. If a persisted Webhook configuration specifies allowed versions and does not include any versions known to the API Server, calls to the webhook will fail.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Status contains derived information about an API server
APIServiceSpec
APIServiceSpec contains information for locating and communicating with a server. Only https is supported, though you are able to disable certificate verification.
Field
Description
caBundle string
CABundle is a PEM encoded CA bundle which will be used to validate an API server's serving certificate. If unspecified, system trust roots on the apiserver are used.
group string
Group is the API group name this server hosts
groupPriorityMinimum* integer
GroupPriorityMinimum is the priority this group should have at least. Higher priority means that the group is preferred by clients over lower priority ones. Note that other versions of this group might specify even higher GroupPriorityMinimum values such that the whole group gets a higher priority. The primary sort is based on GroupPriorityMinimum, ordered highest number to lowest (20 before 10). The secondary sort is based on the alphabetical comparison of the name of the object. (v1.bar before v1.foo) We'd recommend something like: *.k8s.io (except extensions) at 18000 and PaaSes (OpenShift, Deis) are recommended to be in the 2000s
insecureSkipTLSVerify boolean
InsecureSkipTLSVerify disables TLS certificate verification when communicating with this server. This is strongly discouraged. You should use the CABundle instead.
Service is a reference to the service for this API server. It must communicate on port 443. If the Service is nil, that means the handling for the API groupversion is handled locally on this server. The call will simply delegate to the normal handler chain to be fulfilled.
version string
Version is the API version this server hosts. For example, "v1"
versionPriority* integer
VersionPriority controls the ordering of this API version inside of its group. Must be greater than zero. The primary sort is based on VersionPriority, ordered highest to lowest (20 before 10). Since it's inside of a group, the number can be small, probably in the 10s. In case of equal version priorities, the version string will be used to compute the order inside a group. If the version string is "kube-like", it will sort above non "kube-like" version strings, which are ordered lexicographically. "Kube-like" versions start with a "v", then are followed by a number (the major version), then optionally the string "alpha" or "beta" and another number (the minor version). These are sorted first by GA > beta > alpha (where GA is a version with no suffix such as beta or alpha), and then by comparing major version, then minor version. An example sorted list of versions: v10, v2, v1, v11beta2, v10beta3, v3beta1, v12alpha1, v11alpha2, foo1, foo10.
APIServiceStatus
APIServiceStatus contains derived information about an API server

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
GET /apis/apiregistration.k8s.io/v1/watch/apiservices
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results.

sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space.

timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
GET /apis/internal.apiserver.k8s.io/v1alpha1/storageversions
Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force

ControllerRevision implements an immutable snapshot of state data. Clients are responsible for serializing and deserializing the objects that contain their internal state. Once a ControllerRevision has been successfully created, it can not be updated. The API Server will fail validation of all requests that attempt to mutate the Data field. ControllerRevisions may, however, be deleted. Note that, due to its use by both the DaemonSet and StatefulSet controllers for update and rollback, this object is beta. However, it may be subject to name and representation changes in future releases, and clients should not depend on its stability. It is primarily for internal use by controllers.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Rolling update config params. Present only if type = "RollingUpdate".
rollingUpdate.maxSurge
The maximum number of nodes with an existing available DaemonSet pod that can have an updated DaemonSet pod during during an update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up to a minimum of 1. Default value is 0. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their a new pod created before the old pod is marked as deleted. The update starts by launching new pods on 30% of nodes. Once an updated pod is available (Ready for at least minReadySeconds) the old DaemonSet pod on that node is marked deleted. If the old pod becomes unavailable for any reason (Ready transitions to false, is evicted, or is drained) an updated pod is immediately created on that node without considering surge limits. Allowing surge implies the possibility that the resources consumed by the daemonset on any given node can double if the readiness check fails, and so resource intensive daemonsets should take into account that they may cause evictions during disruption.
rollingUpdate.maxUnavailable
The maximum number of DaemonSet pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of total number of DaemonSet pods at the start of the update (ex: 10%). Absolute number is calculated from percentage by rounding up. This cannot be 0 if MaxSurge is 0 Default value is 1. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their pods stopped for an update at any given time. The update starts by stopping at most 30% of those DaemonSet pods and then brings up new DaemonSet pods in their place. Once the new pods are available, it then proceeds onto other DaemonSet pods, thus ensuring that at least 70% of original number of DaemonSet pods are available at all times during the update.
type string
Type of daemon set update. Can be "RollingUpdate" or "OnDelete". Default is RollingUpdate.
Possible enum values: - `"OnDelete"` Replace the old daemons only when it's killed - `"RollingUpdate"` Replace the old daemons by new ones using rolling update i.e replace them on each node one after the other.

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Path Parameters
Name

Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Deployment
Deployment enables declarative updates for Pods and ReplicaSets.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
DeploymentSpec is the specification of the desired behavior of the Deployment.
Field
Description
minReadySeconds integer
Minimum number of seconds for which a newly created pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)
paused boolean
Indicates that the deployment is paused.
progressDeadlineSeconds integer
The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s.
replicas integer
Number of desired pods. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.
revisionHistoryLimit integer
The number of old ReplicaSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.
Label selector for pods. Existing ReplicaSets whose pods are selected by this will be the ones affected by this deployment. It must match the pod template's labels.
Rolling update config params. Present only if DeploymentStrategyType = RollingUpdate.
strategy.rollingUpdate.maxSurge
The maximum number of pods that can be scheduled above the desired number of pods. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 25%. Example: when this is set to 30%, the new ReplicaSet can be scaled up immediately when the rolling update starts, such that the total number of old and new pods do not exceed 130% of desired pods. Once old pods have been killed, new ReplicaSet can be scaled up further, ensuring that total number of pods running at any time during the update is at most 130% of desired pods.
strategy.rollingUpdate.maxUnavailable
The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 25%. Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old ReplicaSet can be scaled down further, followed by scaling up the new ReplicaSet, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.
strategy.type string
Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.
Possible enum values: - `"Recreate"` Kill all existing pods before creating new ones. - `"RollingUpdate"` Replace the old ReplicaSets by new one using rolling update i.e gradually scale down the old ReplicaSets and scale up the new one.
Template describes the pods that will be created. The only allowed template.spec.restartPolicy value is "Always".
DeploymentStatus
DeploymentStatus is the most recently observed status of the Deployment.
Field
Description
availableReplicas integer
Total number of available non-terminating pods (ready for at least minReadySeconds) targeted by this deployment.
collisionCount integer
Count of hash collisions for the Deployment. The Deployment controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ReplicaSet.
Represents the latest available observations of a deployment's current state.
observedGeneration integer
The generation observed by the deployment controller.
readyReplicas integer
Total number of non-terminating pods targeted by this Deployment with a Ready Condition.
replicas integer
Total number of non-terminating pods targeted by this deployment (their labels match the selector).
terminatingReplicas integer
Total number of terminating pods targeted by this deployment. Terminating pods have a non-null .metadata.deletionTimestamp and have not yet reached the Failed or Succeeded .status.phase. This is a beta field and requires enabling DeploymentReplicaSetTerminatingReplicas feature (enabled by default).
unavailableReplicas integer
Total number of unavailable pods targeted by this deployment. This is the total number of pods that are still required for the deployment to have 100% available capacity. They may either be pods that are running but not yet available or pods that still have not been created.
updatedReplicas integer
Total number of non-terminating pods targeted by this deployment that have the desired template spec.
DeploymentList
DeploymentList is a list of Deployments.

When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Path Parameters
Name
Type
Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

dryRun
string

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests.

StatefulSet
StatefulSet represents a set of pods with consistent identities. Identities are defined as:
Network: A single stable DNS and hostname.
Storage: As many VolumeClaims as requested.
The StatefulSet guarantees that a given network identity will always map to the same storage identity.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Status is the current status of Pods in this StatefulSet. This data may be out of date by some window of time.
StatefulSetSpec
A StatefulSetSpec is the specification of a StatefulSet.
Field
Description
minReadySeconds integer
Minimum number of seconds for which a newly created pod should be ready without any of its container crashing for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)
ordinals controls the numbering of replica indices in a StatefulSet. The default ordinals behavior assigns a "0" index to the first replica and increments the index by one for each additional replica requested.
persistentVolumeClaimRetentionPolicy describes the lifecycle of persistent volume claims created from volumeClaimTemplates. By default, all persistent volume claims are created as needed and retained until manually deleted. This policy allows the lifecycle to be altered, for example by deleting persistent volume claims when their stateful set is deleted, or when their pod is scaled down.
podManagementPolicy string
podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down. The default policy is `OrderedReady`, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. When scaling down, the pods are removed in the opposite order. The alternative policy is `Parallel` which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once.
Possible enum values: - `"OrderedReady"` will create pods in strictly increasing order on scale up and strictly decreasing order on scale down, progressing only when the previous pod is ready or terminated. At most one pod will be changed at any time. - `"Parallel"` will create and delete pods as soon as the stateful set replica count is changed, and will not wait for pods to be ready or complete termination.
replicas integer
replicas is the desired number of replicas of the given Template. These are replicas in the sense that they are instantiations of the same Template, but individual replicas also have a consistent identity. If unspecified, defaults to 1.
revisionHistoryLimit integer
revisionHistoryLimit is the maximum number of revisions that will be maintained in the StatefulSet's revision history. The revision history consists of all revisions not represented by a currently applied StatefulSetSpec version. The default value is 10.
selector is a label query over pods that should match the replica count. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors
serviceName string
serviceName is the name of the service that governs this StatefulSet. This service must exist before the StatefulSet, and is responsible for the network identity of the set. Pods get DNS/hostnames that follow the pattern: pod-specific-string.serviceName.default.svc.cluster.local where "pod-specific-string" is managed by the StatefulSet controller.
template is the object that describes the pod that will be created if insufficient replicas are detected. Each pod stamped out by the StatefulSet will fulfill this Template, but have a unique identity from the rest of the StatefulSet. Each pod will be named with the format \-\. For example, a pod in a StatefulSet named "web" with index number "3" would be named "web-3". The only allowed template.spec.restartPolicy value is "Always".
volumeClaimTemplates is a list of claims that pods are allowed to reference. The StatefulSet controller is responsible for mapping network identities to claims in a way that maintains the identity of a pod. Every claim in this list must have at least one matching (by name) volumeMount in one container in the template. A claim in this list takes precedence over any volumes in the template, with the same name.
StatefulSetStatus
StatefulSetStatus represents the current state of a StatefulSet.
Field
Description
availableReplicas integer
Total number of available pods (ready for at least minReadySeconds) targeted by this statefulset.
collisionCount integer
collisionCount is the count of hash collisions for the StatefulSet. The StatefulSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.
Represents the latest available observations of a statefulset's current state.
currentReplicas integer
currentReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by currentRevision.
currentRevision string
currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [0,currentReplicas).
observedGeneration integer
observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the StatefulSet's generation, which is updated on mutation by the API Server.
readyReplicas integer
readyReplicas is the number of pods created for this StatefulSet with a Ready Condition.
replicas* integer
replicas is the number of Pods created by the StatefulSet controller.
updateRevision string
updateRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [replicas-updatedReplicas,replicas)
updatedReplicas integer
updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by updateRevision.
StatefulSetList
StatefulSetList is a collection of StatefulSets.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Standard list's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
RollingUpdateStatefulSetStrategy
RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType.
Field
Description
maxUnavailable
The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding up. This can not be 0. Defaults to 1. This field is beta-level and is enabled by default. The field applies to all pods in the range 0 to Replicas-1. That means if there is any unavailable pod in the range 0 to Replicas-1, it will be counted towards MaxUnavailable. This setting might not be effective for the OrderedReady podManagementPolicy. That policy ensures pods are created and become ready one at a time.
partition integer
Partition indicates the ordinal at which the StatefulSet should be partitioned for updates. During a rolling update, all pods from ordinal Replicas-1 to Partition are updated. All pods from ordinal Partition-1 to 0 remain untouched. This is helpful in being able to do a canary based deployment. The default value is 0.
StatefulSetCondition
StatefulSetCondition describes the state of a statefulset at a certain point.
Last time the condition transitioned from one status to another.
message string
A human readable message indicating details about the transition.
reason string
The reason for the condition's last transition.
status* string
Status of the condition, one of True, False, Unknown.
type* string
Type of statefulset condition.
StatefulSetOrdinals
StatefulSetOrdinals describes the policy used for replica ordinal assignment in this StatefulSet.
Field
Description
start integer
start is the number representing the first replica's index. It may be used to number replicas from an alternate index (eg: 1-indexed) over the default 0-indexed names, or to orchestrate progressive movement of replicas from one StatefulSet to another. If set, replica indices will be in the range: [.spec.ordinals.start, .spec.ordinals.start + .spec.replicas). If unset, defaults to 0. Replica indices will be in the range: [0, .spec.replicas).
StatefulSetPersistentVolumeClaimRetentionPolicy
StatefulSetPersistentVolumeClaimRetentionPolicy describes the policy used for PVCs created from the StatefulSet VolumeClaimTemplates.
Field
Description
whenDeleted string
WhenDeleted specifies what happens to PVCs created from StatefulSet VolumeClaimTemplates when the StatefulSet is deleted. The default policy of `Retain` causes PVCs to not be affected by StatefulSet deletion. The `Delete` policy causes those PVCs to be deleted.
whenScaled string
WhenScaled specifies what happens to PVCs created from StatefulSet VolumeClaimTemplates when the StatefulSet is scaled down. The default policy of `Retain` causes PVCs to not be affected by a scaledown. The `Delete` policy causes the associated PVCs for any excess pods above the replica count to be deleted.
StatefulSetUpdateStrategy
StatefulSetUpdateStrategy indicates the strategy that the StatefulSet controller will use to perform updates. It includes any additional parameters necessary to perform the update for the indicated strategy.
RollingUpdate is used to communicate parameters when Type is RollingUpdateStatefulSetStrategyType.
type string
Type indicates the type of the StatefulSetUpdateStrategy. Default is RollingUpdate.
Possible enum values: - `"OnDelete"` triggers the legacy behavior. Version tracking and ordered rolling restarts are disabled. Pods are recreated from the StatefulSetSpec when they are manually deleted. When a scale operation is performed with this strategy,specification version indicated by the StatefulSet's currentRevision. - `"RollingUpdate"` indicates that update will be applied to all Pods in the StatefulSet with respect to the StatefulSet ordering constraints. When a scale operation is performed with this strategy, new Pods will be created from the specification version indicated by the StatefulSet's updateRevision.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

continue
string
The continue option should be set when retrieving more results from the server.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

HorizontalPodAutoscaler
HorizontalPodAutoscaler is the configuration for a horizontal pod autoscaler, which automatically manages the replica count of any resource implementing the scale subresource based on the metrics specified.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec is the specification for the behaviour of the autoscaler. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status.
behavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively). If not set, the default HPAScalingRules for scale up and scale down are used.
maxReplicas* integer
maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas.
metrics contains the specifications for which to use to calculate the desired replica count (the maximum replica count across all metrics will be used). The desired replica count is calculated multiplying the ratio between the target value and the current value by the current number of pods. Ergo, metrics used must decrease as the pod count is increased, and vice-versa. See the individual metric source types for more information about how each type of metric must respond. If not set, the default metric will be set to 80% average CPU utilization.
minReplicas integer
minReplicas is the lower limit for the number of replicas to which the autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured. Scaling is active as long as at least one metric value is available.
scaleTargetRef points to the target resource to scale, and is used to the pods for which metrics should be collected, as well as to actually change the replica count.
HorizontalPodAutoscalerStatus
HorizontalPodAutoscalerStatus describes the current status of a horizontal pod autoscaler.
lastScaleTime is the last time the HorizontalPodAutoscaler scaled the number of pods, used by the autoscaler to control how often the number of pods is changed.
observedGeneration integer
observedGeneration is the most recent generation observed by this autoscaler.
HorizontalPodAutoscalerList
HorizontalPodAutoscalerList is a list of horizontal pod autoscaler objects.

ContainerResourceMetricSource indicates how to scale on a resource metric known to Kubernetes, as specified in requests and limits, describing each pod in the current scale target (e.g. CPU or memory). The values will be averaged together before being compared to the target. Such metrics are built in to Kubernetes, and have special scaling options on top of those available to normal per-pod metrics using the "pods" source. Only one "target" type should be set.
Field
Description
container* string
container is the name of the container in the pods of the scaling target
target specifies the target value for the given metric
ContainerResourceMetricStatus
ContainerResourceMetricStatus indicates the current value of a resource metric known to Kubernetes, as specified in requests and limits, describing a single container in each pod in the current scale target (e.g. CPU or memory). Such metrics are built in to Kubernetes, and have special scaling options on top of those available to normal per-pod metrics using the "pods" source.
Field

ExternalMetricSource
ExternalMetricSource indicates how to scale on a metric not associated with any Kubernetes object (for example length of queue in cloud messaging service, or QPS from loadbalancer running outside of cluster).
metric identifies the target metric by name and selector
HPAScalingPolicy
HPAScalingPolicy is a single policy which must hold true for a specified past interval.
Field
Description
periodSeconds* integer
periodSeconds specifies the window of time for which the policy should hold true. PeriodSeconds must be greater than zero and less than or equal to 1800 (30 min).
type* string
type is used to specify the scaling policy.
value* integer
value contains the amount of change which is permitted by the policy. It must be greater than zero
HPAScalingRules
HPAScalingRules configures the scaling behavior for one direction via scaling Policy Rules and a configurable metric tolerance.
Scaling Policy Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies. They can prevent flapping by specifying the stabilization window, so that the number of replicas is not set instantly, instead, the safest value from the stabilization window is chosen.
The tolerance is applied to the metric values and prevents scaling too eagerly for small metric variations. (Note that setting a tolerance requires the beta HPAConfigurableTolerance feature gate to be enabled.)
policies is a list of potential scaling polices which can be used during scaling. If not set, use the default values: - For scale up: allow doubling the number of pods, or an absolute change of 4 pods in a 15s window. - For scale down: allow all pods to be removed in a 15s window.
selectPolicy string
selectPolicy is used to specify which policy should be used. If not set, the default value Max is used.
stabilizationWindowSeconds integer
stabilizationWindowSeconds is the number of seconds for which past recommendations should be considered while scaling up or scaling down. StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour). If not set, use the default values: - For scale up: 0 (i.e. no stabilization is done). - For scale down: 300 (i.e. the stabilization window is 300 seconds long).
tolerance is the tolerance on the ratio between the current and desired metric value under which no updates are made to the desired number of replicas (e.g. 0.01 for 1%). Must be greater than or equal to zero. If not set, the default cluster-wide tolerance is applied (by default 10%). For example, if autoscaling is configured with a memory consumption target of 100Mi, and scale-down and scale-up tolerances of 5% and 1% respectively, scaling will be triggered when the actual consumption falls below 95Mi or exceeds 101Mi. This is an beta field and requires the HPAConfigurableTolerance feature gate to be enabled.
HorizontalPodAutoscalerBehavior
HorizontalPodAutoscalerBehavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively).
scaleDown is scaling policy for scaling Down. If not set, the default value is to allow to scale down to minReplicas pods, with a 300 second stabilization window (i.e., the highest recommendation for the last 300sec is used).
scaleUp is scaling policy for scaling Up. If not set, the default value is the higher of: * increase no more than 4 pods per 60 seconds * double the number of pods per 60 seconds No stabilization is used.
HorizontalPodAutoscalerCondition
HorizontalPodAutoscalerCondition describes the state of a HorizontalPodAutoscaler at a certain point.
selector is the string-encoded form of a standard kubernetes label selector for the given metric When set, it is passed as an additional parameter to the metrics server for more specific metrics scoping. When unset, just the metricName will be used to gather metrics.

pods refers to a metric describing each pod in the current scale target (for example, transactions-processed-per-second). The values will be averaged together before being compared to the target value.
resource refers to a resource metric (such as those specified in requests and limits) known to Kubernetes describing each pod in the current scale target (e.g. CPU or memory). Such metrics are built in to Kubernetes, and have special scaling options on top of those available to normal per-pod metrics using the "pods" source.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

Name

Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
GET /apis/autoscaling/v2/watch/horizontalpodautoscalers
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents

continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds

If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Specification of the desired behavior of a job. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
Current status of a job. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
JobSpec
JobSpec describes how the job execution will look like.
Field
Description
activeDeadlineSeconds integer
Specifies the duration in seconds relative to the startTime that the job may be continuously active before the system tries to terminate it; value must be positive integer. If a Job is suspended (at creation or through an update), this timer will effectively be stopped and reset when the Job is resumed again.
backoffLimit integer
Specifies the number of retries before marking this job failed. Defaults to 6, unless backoffLimitPerIndex (only Indexed Job) is specified. When backoffLimitPerIndex is specified, backoffLimit defaults to 2147483647.
backoffLimitPerIndex integer
Specifies the limit for the number of retries within an index before marking this index as failed. When enabled the number of failures per index is kept in the pod's batch.kubernetes.io/job-index-failure-count annotation. It can only be set when Job's completionMode=Indexed, and the Pod's restart policy is Never. The field is immutable.
completionMode string
completionMode specifies how Pod completions are tracked. It can be `NonIndexed` (default) or `Indexed`. `NonIndexed` means that the Job is considered complete when there have been .spec.completions successfully completed Pods. Each Pod completion is homologous to each other. `Indexed` means that the Pods of a Job get an associated completion index from 0 to (.spec.completions - 1), available in the annotation batch.kubernetes.io/job-completion-index. The Job is considered complete when there is one successfully completed Pod for each index. When value is `Indexed`, .spec.completions must be specified and `.spec.parallelism` must be less than or equal to 10^5. In addition, The Pod name takes the form `$(job-name)-$(index)-$(random-string)`, the Pod hostname takes the form `$(job-name)-$(index)`. More completion modes can be added in the future. If the Job controller observes a mode that it doesn't recognize, which is possible during upgrades due to version skew, the controller skips updates for the Job.
Possible enum values: - `"Indexed"` is a Job completion mode. In this mode, the Pods of a Job get an associated completion index from 0 to (.spec.completions - 1). The Job is considered complete when a Pod completes for each completion index. - `"NonIndexed"` is a Job completion mode. In this mode, the Job is considered complete when there have been .spec.completions successfully completed Pods. Pod completions are homologous to each other.
completions integer
Specifies the desired number of successfully finished pods the job should be run with. Setting to null means that the success of any pod signals the success of all pods, and allows parallelism to have any positive value. Setting to 1 means that parallelism is limited to 1 and the success of that pod signals the success of the job. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/
managedBy string
ManagedBy field indicates the controller that manages a Job. The k8s Job controller reconciles jobs which don't have this field at all or the field value is the reserved string `kubernetes.io/job-controller`, but skips reconciling Jobs with a custom value for this field. The value must be a valid domain-prefixed path (e.g. acme.io/foo) - all characters before the first "/" must be a valid subdomain as defined by RFC 1123. All characters trailing the first "/" must be valid HTTP Path characters as defined by RFC 3986. The value cannot exceed 63 characters. This field is immutable.
manualSelector boolean
manualSelector controls generation of pod labels and pod selectors. Leave `manualSelector` unset unless you are certain what you are doing. When false or unset, the system pick labels unique to this job and appends those labels to the pod template. When true, the user is responsible for picking unique labels and specifying the selector. Failure to pick a unique label may cause this and other jobs to not function correctly. However, You may see `manualSelector=true` in jobs that were created with the old `extensions/v1beta1` API. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/#specifying-your-own-pod-selector
maxFailedIndexes integer
Specifies the maximal number of failed indexes before marking the Job as failed, when backoffLimitPerIndex is set. Once the number of failed indexes exceeds this number the entire Job is marked as Failed and its execution is terminated. When left as null the job continues execution of all of its indexes and is marked with the `Complete` Job condition. It can only be specified when backoffLimitPerIndex is set. It can be null or up to completions. It is required and must be less than or equal to 10^4 when is completions greater than 10^5.
parallelism integer
Specifies the maximum desired number of pods the job should run at any given time. The actual number of pods running in steady state will be less than this number when ((.spec.completions - .status.successful) \< .spec.parallelism), i.e. when the work left to do is less than max parallelism. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/
Specifies the policy of handling failed pods. In particular, it allows to specify the set of actions and conditions which need to be satisfied to take the associated action. If empty, the default behaviour applies - the counter of failed pods, represented by the jobs's .status.failed field, is incremented and it is checked against the backoffLimit. This field cannot be used in combination with restartPolicy=OnFailure.
podReplacementPolicy string
podReplacementPolicy specifies when to create replacement Pods. Possible values are: - TerminatingOrFailed means that we recreate pods when they are terminating (has a metadata.deletionTimestamp) or failed. - Failed means to wait until a previously created Pod is fully terminated (has phase Failed or Succeeded) before creating a replacement Pod. When using podFailurePolicy, Failed is the the only allowed value. TerminatingOrFailed and Failed are allowed values when podFailurePolicy is not in use.
Possible enum values: - `"Failed"` means to wait until a previously created Pod is fully terminated (has phase Failed or Succeeded) before creating a replacement Pod. - `"TerminatingOrFailed"` means that we recreate pods when they are terminating (has a metadata.deletionTimestamp) or failed.
A label query over pods that should match the pod count. Normally, the system sets this field for you. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors
successPolicy specifies the policy when the Job can be declared as succeeded. If empty, the default behavior applies - the Job is declared as succeeded only when the number of succeeded pods equals to the completions. When the field is specified, it must be immutable and works only for the Indexed Jobs. Once the Job meets the SuccessPolicy, the lingering pods are terminated.
suspend boolean
suspend specifies whether the Job controller should create Pods or not. If a Job is created with suspend set to true, no Pods are created by the Job controller. If a Job is suspended after creation (i.e. the flag goes from false to true), the Job controller will delete all active Pods associated with this Job. Users must design their workload to gracefully handle this. Suspending a Job will reset the StartTime field of the Job, effectively resetting the ActiveDeadlineSeconds timer too. Defaults to false.
Describes the pod that will be created when executing a job. The only allowed template.spec.restartPolicy values are "Never" or "OnFailure". More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/
ttlSecondsAfterFinished integer
ttlSecondsAfterFinished limits the lifetime of a Job that has finished execution (either Complete or Failed). If this field is set, ttlSecondsAfterFinished after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is unset, the Job won't be automatically deleted. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes.
JobStatus
JobStatus represents the current state of a Job.
Field
Description
active integer
The number of pending and running pods which are not terminating (without a deletionTimestamp). The value is zero for finished jobs.
completedIndexes string
completedIndexes holds the completed indexes when .spec.completionMode = "Indexed" in a text format. The indexes are represented as decimal integers separated by commas. The numbers are listed in increasing order. Three or more consecutive numbers are compressed and represented by the first and last element of the series, separated by a hyphen. For example, if the completed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7".
Represents time when the job was completed. It is not guaranteed to be set in happens-before order across separate operations. It is represented in RFC3339 form and is in UTC. The completion time is set when the job finishes successfully, and only then. The value cannot be updated or removed. The value indicates the same or later point in time as the startTime field.
The latest available observations of an object's current state. When a Job fails, one of the conditions will have type "Failed" and status true. When a Job is suspended, one of the conditions will have type "Suspended" and status true; when the Job is resumed, the status of this condition will become false. When a Job is completed, one of the conditions will have type "Complete" and status true. A job is considered finished when it is in a terminal condition, either "Complete" or "Failed". A Job cannot have both the "Complete" and "Failed" conditions. Additionally, it cannot be in the "Complete" and "FailureTarget" conditions. The "Complete", "Failed" and "FailureTarget" conditions cannot be disabled. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/
failed integer
The number of pods which reached phase Failed. The value increases monotonically.
failedIndexes string
FailedIndexes holds the failed indexes when spec.backoffLimitPerIndex is set. The indexes are represented in the text format analogous as for the `completedIndexes` field, ie. they are kept as decimal integers separated by commas. The numbers are listed in increasing order. Three or more consecutive numbers are compressed and represented by the first and last element of the series, separated by a hyphen. For example, if the failed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7". The set of failed indexes cannot overlap with the set of completed indexes.
ready integer
The number of active pods which have a Ready condition and are not terminating (without a deletionTimestamp).
Represents time when the job controller started processing a job. When a Job is created in the suspended state, this field is not set until the first time it is resumed. This field is reset every time a Job is resumed from suspension. It is represented in RFC3339 form and is in UTC. Once set, the field can only be removed when the job is suspended. The field cannot be modified while the job is unsuspended or finished.
succeeded integer
The number of pods which reached phase Succeeded. The value increases monotonically for a given spec. However, it may decrease in reaction to scale down of elastic indexed jobs.
terminating integer
The number of pods which are terminating (in phase Pending or Running and have a deletionTimestamp). This field is beta-level. The job controller populates the field when the feature gate JobPodReplacementPolicy is enabled (enabled by default).
uncountedTerminatedPods holds the UIDs of Pods that have terminated but the job controller hasn't yet accounted for in the status counters. The job controller creates pods with a finalizer. When a pod terminates (succeeded or failed), the controller does three steps to account for it in the job status: 1. Add the pod UID to the arrays in this field. 2. Remove the pod finalizer. 3. Remove the pod UID from the arrays while increasing the corresponding counter. Old jobs might not be tracked using this field, in which case the field remains null. The structure is empty for finished jobs.
JobList
JobList is a collection of jobs.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
A list of pod failure policy rules. The rules are evaluated in order. Once a rule matches a Pod failure, the remaining of the rules are ignored. When no rule matches the Pod failure, the default handling applies - the counter of pod failures is incremented and it is checked against the backoffLimit. At most 20 elements are allowed.
PodFailurePolicyOnExitCodesRequirement
PodFailurePolicyOnExitCodesRequirement describes the requirement for handling a failed pod based on its container exit codes. In particular, it lookups the .state.terminated.exitCode for each app container and init container status, represented by the .status.containerStatuses and .status.initContainerStatuses fields in the Pod status, respectively. Containers completed with success (exit code 0) are excluded from the requirement check.
Field
Description
containerName string
Restricts the check for exit codes to the container with the specified name. When null, the rule applies to all containers. When specified, it should match one the container or initContainer names in the pod template.
operator* string
Represents the relationship between the container exit code(s) and the specified values. Containers completed with success (exit code 0) are excluded from the requirement check. Possible values are: - In: the requirement is satisfied if at least one container exit code (might be multiple if there are multiple containers not restricted by the 'containerName' field) is in the set of specified values. - NotIn: the requirement is satisfied if at least one container exit code (might be multiple if there are multiple containers not restricted by the 'containerName' field) is not in the set of specified values. Additional values are considered to be added in the future. Clients should react to an unknown operator by assuming the requirement is not satisfied.
Possible enum values: - `"In"` - `"NotIn"`
values* integer array
Specifies the set of values. Each returned container exit code (might be multiple in case of multiple containers) is checked against this set of values with respect to the operator. The list of values must be ordered and must not contain duplicates. Value '0' cannot be used for the In operator. At least one element is required. At most 255 elements are allowed.
PodFailurePolicyOnPodConditionsPattern
PodFailurePolicyOnPodConditionsPattern describes a pattern for matching an actual pod condition type.
Field
Description
status string
Specifies the required Pod condition status. To match a pod condition it is required that the specified status equals the pod condition status. Defaults to True.
type* string
Specifies the required Pod condition type. To match a pod condition it is required that specified type equals the pod condition type.
PodFailurePolicyRule
PodFailurePolicyRule describes how a pod failure is handled when the requirements are met. One of onExitCodes and onPodConditions, but not both, can be used in each rule.
Field
Description
action* string
Specifies the action taken on a pod failure when the requirements are satisfied. Possible values are: - FailJob: indicates that the pod's job is marked as Failed and all running pods are terminated. - FailIndex: indicates that the pod's index is marked as Failed and will not be restarted. - Ignore: indicates that the counter towards the .backoffLimit is not incremented and a replacement pod is created. - Count: indicates that the pod is handled in the default way - the counter towards the .backoffLimit is incremented. Additional values are considered to be added in the future. Clients should react to an unknown action by skipping the rule.
Possible enum values: - `"Count"` This is an action which might be taken on a pod failure - the pod failure is handled in the default way - the counter towards .backoffLimit, represented by the job's .status.failed field, is incremented. - `"FailIndex"` This is an action which might be taken on a pod failure - mark the Job's index as failed to avoid restarts within this index. This action can only be used when backoffLimitPerIndex is set. - `"FailJob"` This is an action which might be taken on a pod failure - mark the pod's job as Failed and terminate all running pods. - `"Ignore"` This is an action which might be taken on a pod failure - the counter towards .backoffLimit, represented by the job's .status.failed field, is not incremented and a replacement pod is created.
Represents the requirement on the pod conditions. The requirement is represented as a list of pod condition patterns. The requirement is satisfied if at least one pattern matches an actual pod condition. At most 20 elements are allowed.
SuccessPolicy
SuccessPolicy describes when a Job can be declared as succeeded based on the success of some indexes.
rules represents the list of alternative rules for the declaring the Jobs as successful before `.status.succeeded >= .spec.completions`. Once any of the rules are met, the "SuccessCriteriaMet" condition is added, and the lingering pods are removed. The terminal state for such a Job has the "Complete" condition. Additionally, these rules are evaluated in order; Once the Job meets one of the rules, other rules are ignored. At most 20 elements are allowed.
SuccessPolicyRule
SuccessPolicyRule describes rule for declaring a Job as succeeded. Each rule must have at least one of the "succeededIndexes" or "succeededCount" specified.
Field
Description
succeededCount integer
succeededCount specifies the minimal required size of the actual set of the succeeded indexes for the Job. When succeededCount is used along with succeededIndexes, the check is constrained only to the set of indexes specified by succeededIndexes. For example, given that succeededIndexes is "1-4", succeededCount is "3", and completed indexes are "1", "3", and "5", the Job isn't declared as succeeded because only "1" and "3" indexes are considered in that rules. When this field is null, this doesn't default to any value and is never evaluated at any time. When specified it needs to be a positive integer.
succeededIndexes string
succeededIndexes specifies the set of indexes which need to be contained in the actual set of the succeeded indexes for the Job. The list of indexes must be within 0 to ".spec.completions-1" and must not contain duplicates. At least one element is required. The indexes are represented as intervals separated by commas. The intervals can be a decimal integer or a pair of decimal integers separated by a hyphen. The number are listed in represented by the first and last element of the series, separated by a hyphen. For example, if the completed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7". When this field is null, this field doesn't default to any value and is never evaluated at any time.
UncountedTerminatedPods
UncountedTerminatedPods holds UIDs of Pods that have terminated but haven't been accounted in Job status counters.
Field
Description
failed string array
failed holds UIDs of failed Pods.
succeeded string array
succeeded holds UIDs of succeeded Pods.

object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean

The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Path Parameters
Name
Type
Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

CertificateSigningRequest objects provide a mechanism to obtain x509 certificates by submitting a certificate signing request, and having it asynchronously approved and issued.
Kubelets use this API to obtain:
client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client-kubelet" signerName).
serving certificates for TLS endpoints kube-apiserver can connect to securely (with the "kubernetes.io/kubelet-serving" signerName).
This API can be used to request client certificates to authenticate to kube-apiserver (with the "kubernetes.io/kube-apiserver-client" signerName), or to obtain certificates from custom non-Kubernetes signers.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec contains the certificate request, and is immutable after creation. Only the request, signerName, expirationSeconds, and usages fields can be set on creation. Other fields are derived by Kubernetes and cannot be modified by users.
status contains information about whether the request is approved or denied, and the certificate issued by the signer, or the failure condition indicating signer failure.
CertificateSigningRequestSpec
CertificateSigningRequestSpec contains the certificate request.
Field
Description
expirationSeconds integer
expirationSeconds is the requested duration of validity of the issued certificate. The certificate signer may issue a certificate with a different validity duration so a client must check the delta between the notBefore and and notAfter fields in the issued certificate to determine the actual duration. The v1.22+ in-tree implementations of the well-known Kubernetes signers will honor this field as long as the requested duration is not greater than the maximum duration they will honor per the --cluster-signing-duration CLI flag to the Kubernetes controller manager. Certificate signers may not honor this field for various reasons: 1. Old signer that is unaware of the field (such as the in-tree implementations prior to v1.22) 2. Signer whose configured maximum is shorter than the requested duration 3. Signer whose configured minimum is longer than the requested duration The minimum valid value for expirationSeconds is 600, i.e. 10 minutes.
extra object
extra contains extra attributes of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
groups string array
groups contains group membership of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
request* string
request contains an x509 certificate signing request encoded in a "CERTIFICATE REQUEST" PEM block. When serialized as JSON or YAML, the data is additionally base64-encoded.
signerName* string
signerName indicates the requested signer, and is a qualified name. List/watch requests for CertificateSigningRequests can filter on this field using a "spec.signerName=NAME" fieldSelector. Well-known Kubernetes signers are: 1. "kubernetes.io/kube-apiserver-client": issues client certificates that can be used to authenticate to kube-apiserver. Requests for this signer are never auto-approved by kube-controller-manager, can be issued by the "csrsigning" controller in kube-controller-manager. 2. "kubernetes.io/kube-apiserver-client-kubelet": issues client certificates that kubelets use to authenticate to kube-apiserver. Requests for this signer can be auto-approved by the "csrapproving" controller in kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager. 3. "kubernetes.io/kubelet-serving" issues serving certificates that kubelets use to serve TLS endpoints, which kube-apiserver can connect to securely. Requests for this signer are never auto-approved by kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager. More details are available at https://k8s.io/docs/reference/access-authn-authz/certificate-signing-requests/#kubernetes-signers Custom signerNames can also be specified. The signer defines: 1. Trust distribution: how trust (CA bundles) are distributed. 2. Permitted subjects: and behavior when a disallowed subject is requested. 3. Required, permitted, or forbidden x509 extensions in the request (including whether subjectAltNames are allowed, which types, restrictions on allowed values) and behavior when a disallowed extension is requested. 4. Required, permitted, or forbidden key usages / extended key usages. 5. Expiration/certificate lifetime: whether it is fixed by the signer, configurable by the admin. 6. Whether or not requests for CA certificates are allowed.
uid string
uid contains the uid of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
usages string array
usages specifies a set of key usages requested in the issued certificate. Requests for TLS client certificates typically request: "digital signature", "key encipherment", "client auth". Requests for TLS serving certificates typically request: "key encipherment", "digital signature", "server auth". Valid values are: "signing", "digital signature", "content commitment", "key encipherment", "key agreement", "data encipherment", "cert sign", "crl sign", "encipher only", "decipher only", "any", "server auth", "client auth", "code signing", "email protection", "s/mime", "ipsec end system", "ipsec tunnel", "ipsec user", "timestamping", "ocsp signing", "microsoft sgc", "netscape sgc"
username string
username contains the name of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
CertificateSigningRequestStatus
CertificateSigningRequestStatus contains conditions used to indicate approved/denied/failed status of the request, and the issued certificate.
Field
Description
certificate string
certificate is populated with an issued certificate by the signer after an Approved condition is present. This field is set via the /status subresource. Once populated, this field is immutable. If the certificate signing request is denied, a condition of type "Denied" is added and this field remains empty. If the signer cannot issue the certificate, a condition of type "Failed" is added and this field remains empty. Validation requirements: 1. certificate must contain one or more PEM blocks. 2. All PEM blocks must have the "CERTIFICATE" label, contain no headers, and the encoded data must be a BER-encoded ASN.1 Certificate structure as described in section 4 of RFC5280. 3. Non-PEM content may appear before or after the "CERTIFICATE" PEM blocks and is unvalidated, to allow for explanatory text as described in section 5.2 of RFC7468. If more than one PEM block is present, and the definition of the requested spec.signerName does not indicate otherwise, the first block is the issued certificate, and subsequent blocks should be treated as intermediate certificates and presented in TLS handshakes. The certificate is encoded in PEM format. When serialized as JSON or YAML, the data is additionally base64-encoded, so it consists of: base64( -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- )
conditions applied to the request. Known conditions are "Approved", "Denied", and "Failed".
CertificateSigningRequestList
CertificateSigningRequestList is a collection of CertificateSigningRequest objects
Field
Description

type* string
type of the condition. Known conditions are "Approved", "Denied", and "Failed". An "Approved" condition is added via the /approval subresource, indicating the request was approved and should be issued by the signer. A "Denied" condition is added via the /approval subresource, indicating the request was denied and should not be issued by the signer. A "Failed" condition is added via the /status subresource, indicating the signer failed to issue the certificate. Approved and Denied conditions are mutually exclusive. Approved, Denied, and Failed conditions cannot be removed once added. Only one condition of a given type is allowed.

If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

ClusterTrustBundle is a cluster-scoped container for X.509 trust anchors (root certificates).
ClusterTrustBundle objects are considered to be readable by any authenticated user in the cluster, because they can be mounted by pods using the clusterTrustBundle projection. All service accounts have read access to ClusterTrustBundles by default. Users who only have namespace-level access to a cluster can read ClusterTrustBundles by impersonating a serviceaccount that they have access to.
It can be optionally associated with a particular assigner, in which case it contains one valid set of trust anchors for that signer. Signers may have multiple associated ClusterTrustBundles; each is an independent set of trust anchors for that signer. Admission control is used to enforce that only users with permissions on the signer can create or modify the corresponding bundle.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec contains the signer (if any) and trust anchors.
ClusterTrustBundleSpec
ClusterTrustBundleSpec contains the signer and trust anchors.
Field
Description
signerName string
signerName indicates the associated signer, if any. In order to create or update a ClusterTrustBundle that sets signerName, you must have the following cluster-scoped permission: group=certificates.k8s.io resource=signers resourceName=\ verb=attest. If signerName is not empty, then the ClusterTrustBundle object must be named with the signer name as a prefix (translating slashes to colons). For example, for the signer name `example.com/foo`, valid ClusterTrustBundle object names include `example.com:foo:abc` and `example.com:foo:v1`. If signerName is empty, then the ClusterTrustBundle object's name must not have such a prefix. List/watch requests for ClusterTrustBundles can filter on this field using a `spec.signerName=NAME` field selector.
trustBundle* string
trustBundle contains the individual X.509 trust anchors for this bundle, as PEM bundle of PEM-wrapped, DER-formatted X.509 certificates. The data must consist only of PEM certificate blocks that parse as valid X.509 certificates. Each certificate must include a basic constraints extension with the CA bit set. The API server will reject objects that contain duplicate certificates, or that use PEM block headers. Users of ClusterTrustBundles, including Kubelet, are free to reorder and deduplicate certificate blocks in this file according to their own logic, as well as to drop PEM block headers and inter-block data.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field.

A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

PodCertificateRequest
PodCertificateRequest encodes a pod requesting a certificate from a given signer.
Kubelets use this API to implement podCertificate projected volumes
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
status contains the issued certificate, and a standard set of conditions.
PodCertificateRequestSpec
PodCertificateRequestSpec describes the certificate request. All fields are immutable after creation.
Field
Description
maxExpirationSeconds integer
maxExpirationSeconds is the maximum lifetime permitted for the certificate. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime *shorter* than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. `kubernetes.io` signers will never issue certificates with a lifetime longer than 24 hours.
nodeName* string
nodeName is the name of the node the pod is assigned to.
nodeUID* string
nodeUID is the UID of the node the pod is assigned to.
pkixPublicKey string
The PKIX-serialized public key the signer will issue the certificate to. The key must be one of RSA3072, RSA4096, ECDSAP256, ECDSAP384, ECDSAP521, or ED25519. Note that this list may be expanded in the future. Signer implementations do not need to support all key types supported by kube-apiserver and kubelet. If a signer does not support the key type used for a given PodCertificateRequest, it must deny the request by setting a status.conditions entry with a type of "Denied" and a reason of "UnsupportedKeyType". It may also suggest a key type that it does support in the message field. Deprecated: This field is replaced by StubPKCS10Request. If StubPKCS10Request is set, this field must be empty. Signer implementations should extract the public key from the StubPKCS10Request field.
podName* string
podName is the name of the pod into which the certificate will be mounted.
podUID* string
podUID is the UID of the pod into which the certificate will be mounted.
proofOfPossession string
A proof that the requesting kubelet holds the private key corresponding to pkixPublicKey. It is contructed by signing the ASCII bytes of the pod's UID using `pkixPublicKey`. kube-apiserver validates the proof of possession during creation of the PodCertificateRequest. If the key is an RSA key, then the signature is over the ASCII bytes of the pod UID, using RSASSA-PSS from RFC 8017 (as implemented by the golang function crypto/rsa.SignPSS with nil options). If the key is an ECDSA key, then the signature is as described by [SEC 1, Version 2.0](https://www.secg.org/sec1-v2.pdf) (as implemented by the golang library function crypto/ecdsa.SignASN1) If the key is an ED25519 key, the the signature is as described by the [ED25519 Specification](https://ed25519.cr.yp.to/) (as implemented by the golang library crypto/ed25519.Sign). Deprecated: This field is replaced by StubPKCS10Request. If StubPKCS10Request is set, this field must be empty.
serviceAccountName* string
serviceAccountName is the name of the service account the pod is running as.
serviceAccountUID* string
serviceAccountUID is the UID of the service account the pod is running as.
signerName* string
signerName indicates the requested signer. All signer names beginning with `kubernetes.io` are reserved for use by the Kubernetes project. There is currently one well-known signer documented by the Kubernetes project, `kubernetes.io/kube-apiserver-client-pod`, which will issue client certificates understood by kube-apiserver. It is currently unimplemented.
stubPKCS10Request* string
A PKCS#10 certificate signing request (DER-serialized) generated by Kubelet using the subject private key. Most signer implementations will ignore the contents of the CSR except to extract the subject public key. The API server automatically verifies the CSR signature during admission, so the signer does not need to repeat the verification. CSRs generated by kubelet are completely empty. The subject public key must be one of RSA3072, RSA4096, ECDSAP256, ECDSAP384, ECDSAP521, or ED25519. Note that this list may be expanded in the future. Signer implementations do not need to support all key types supported by kube-apiserver and kubelet. If a signer does not support the key type used for a given PodCertificateRequest, it must deny the request by setting a status.conditions entry with a type of "Denied" and a reason of "UnsupportedKeyType". It may also suggest a key type that it does support in the message field.
unverifiedUserAnnotations object
unverifiedUserAnnotations allow pod authors to pass additional information to the signer implementation. Kubernetes does not restrict or validate this metadata in any way. Entries are subject to the same validation as object metadata annotations, with the addition that all keys must be domain-prefixed. No restrictions are placed on values, except an overall size limitation on the entire field. Signers should document the keys and values they support. Signers should deny requests that contain keys they do not recognize.
PodCertificateRequestStatus
PodCertificateRequestStatus describes the status of the request, and holds the certificate data if the request is issued.
beginRefreshAt is the time at which the kubelet should begin trying to refresh the certificate. This field is set via the /status subresource, and must be set at the same time as certificateChain. Once populated, this field is immutable. This field is only a hint. Kubelet may start refreshing before or after this time if necessary.
certificateChain string
certificateChain is populated with an issued certificate by the signer. This field is set via the /status subresource. Once populated, this field is immutable. If the certificate signing request is denied, a condition of type "Denied" is added and this field remains empty. If the signer cannot issue the certificate, a condition of type "Failed" is added and this field remains empty. Validation requirements: 1. certificateChain must consist of one or more PEM-formatted certificates. 2. Each entry must be a valid PEM-wrapped, DER-encoded ASN.1 Certificate as described in section 4 of RFC5280. If more than one block is present, and the definition of the requested spec.signerName does not indicate otherwise, the first block is the issued certificate, and subsequent blocks should be treated as intermediate certificates and presented in TLS handshakes. When projecting the chain into a pod volume, kubelet will drop any data in-between the PEM blocks, as well as any PEM block headers.
conditions Condition array patch strategy: merge on key type
conditions applied to the request. The types "Issued", "Denied", and "Failed" have special handling. At most one of these conditions may be present, and they must have status "True". If the request is denied with `Reason=UnsupportedKeyType`, the signer may suggest a key type that will work in the message field.
notAfter is the time at which the certificate expires. The value must be the same as the notAfter value in the leaf certificate in certificateChain. This field is set via the /status subresource. Once populated, it is immutable. The signer must set this field at the same time it sets certificateChain.
notBefore is the time at which the certificate becomes valid. The value must be the same as the notBefore value in the leaf certificate in certificateChain. This field is set via the /status subresource. Once populated, it is immutable. The signer must set this field at the same time it sets certificateChain.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

acquireTime is a time when the current lease was acquired.
holderIdentity string
holderIdentity contains the identity of the holder of a current lease. If Coordinated Leader Election is used, the holder identity must be equal to the elected LeaseCandidate.metadata.name field.
leaseDurationSeconds integer
leaseDurationSeconds is a duration that candidates for a lease need to wait to force acquire it. This is measured against the time of last observed renewTime.
leaseTransitions integer
leaseTransitions is the number of transitions of a lease between holders.
preferredHolder string
PreferredHolder signals to a lease holder that the lease has a more optimal holder and should be given up. This field can only be set if Strategy is also set.
renewTime is a time when the current holder of a lease has last updated the lease.
strategy string
Strategy indicates the strategy for picking the leader for coordinated leader election. If the field is not specified, there is no active coordination for this lease. (Alpha) Using this field requires the CoordinatedLeaderElection feature gate to be enabled.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Path Parameters
Name
Type
Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

LeaseCandidate
LeaseCandidate defines a candidate for a Lease object. Candidates are created such that coordinated leader election will pick the best leader from the list of candidates.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec contains the specification of the Lease. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
LeaseCandidateSpec
LeaseCandidateSpec is a specification of a Lease.
Field
Description
binaryVersion* string
BinaryVersion is the binary version. It must be in a semver format without leading `v`. This field is required.
emulationVersion string
EmulationVersion is the emulation version. It must be in a semver format without leading `v`. EmulationVersion must be less than or equal to BinaryVersion. This field is required when strategy is "OldestEmulationVersion"
leaseName* string
LeaseName is the name of the lease for which this candidate is contending. The limits on this field are the same as on Lease.name. Multiple lease candidates may reference the same Lease.name. This field is immutable.
PingTime is the last time that the server has requested the LeaseCandidate to renew. It is only done during leader election to check if any LeaseCandidates have become ineligible. When PingTime is updated, the LeaseCandidate will respond by updating RenewTime.
RenewTime is the time that the LeaseCandidate was last updated. Any time a Lease needs to do leader election, the PingTime field is updated to signal to the LeaseCandidate that they should update the RenewTime. Old LeaseCandidate objects are also garbage collected if it has been hours since the last renew. The PingTime field is updated regularly to prevent garbage collection for still active LeaseCandidates.
strategy* string
Strategy is the strategy that coordinated leader election will use for picking the leader. If multiple candidates for the same Lease return different strategies, the strategy provided by the candidate with the latest BinaryVersion will be used. If there is still conflict, this is a user error and coordinated leader election will not operate the Lease until resolved.
LeaseCandidateList
LeaseCandidateList is a list of Lease objects.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
GET /apis/coordination.k8s.io/v1beta1/watch/leasecandidates
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset

boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
Event is a report of an event somewhere in the cluster. It generally denotes some state change in the system. Events have a limited retention time and triggers and messages may evolve with time. Event consumers should not rely on the timing of an event with a given Reason reflecting a consistent underlying trigger, or the continued existence of events with that Reason. Events should be treated as informative, best-effort, supplemental data.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.

resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space.

Path Parameters
Name

Description
namespace
string
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents

The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results.

resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set.

Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
The set of all endpoints is the union of all subsets. Addresses are placed into subsets according to the IPs they share. A single address with multiple ports, some of which are ready and some of which are not (because they come from different containers) will result in the address being displayed in different subsets for the different ports. No address will appear in both Addresses and NotReadyAddresses in the same subset. Sets of addresses and ports that comprise a service.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available.

Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation.

Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
Event is a report of an event somewhere in the cluster. Events have a limited retention time and triggers and messages may evolve with time. Event consumers should not rely on the timing of an event with a given Reason reflecting a consistent underlying trigger, or the continued existence of events with that Reason. Events should be treated as informative, best-effort, supplemental data.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field.

pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector

A selector to restrict the list of returned objects by their fields. Defaults to everything.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.

Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion.

If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds

fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

Node
Node is a worker node in Kubernetes. Each node will have a unique identifier in the cache (i.e. in etcd).
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Most recently observed status of the node. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
NodeSpec
NodeSpec describes the attributes that a node is created with.
Deprecated: Previously used to specify the source of the node's configuration for the DynamicKubeletConfig feature. This feature is removed.
externalID string
Deprecated. Not all kubelets will set this field. Remove field after 1.13. see: https://issues.k8s.io/61966
podCIDR string
PodCIDR represents the pod IP range assigned to the node.
podCIDRs string array patch strategy: merge
podCIDRs represents the IP ranges assigned to the node for usage by Pods on that node. If this field is specified, the 0th entry must match the podCIDR field. It may contain at most 1 value for each of IPv4 and IPv6.
providerID string
ID of the node assigned by the cloud provider in the format: \://\
Unschedulable controls node schedulability of new pods. By default, node is schedulable. More info: https://kubernetes.io/docs/concepts/nodes/node/#manual-node-administration
NodeStatus
NodeStatus is information about the current status of a node.
List of addresses reachable to the node. Queried from cloud provider, if available. More info: https://kubernetes.io/docs/reference/node/node-status/#addresses Note: This field is declared as mergeable, but the merge key is not sufficiently unique, which can cause data corruption when it is merged. Callers should instead use a full-replacement patch. See https://pr.k8s.io/79391 for an example. Consumers should assume that addresses can change during the lifetime of a Node. However, there are some exceptions where this may not be possible, such as Pods that inherit a Node's address in its own status or consumers of the downward API (status.hostIP).
allocatable object
Allocatable represents the resources of a node that are available for scheduling. Defaults to Capacity.
capacity object
Capacity represents the total resources of a node. More info: https://kubernetes.io/docs/reference/node/node-status/#capacity
Set of ids/uuids to uniquely identify the node. More info: https://kubernetes.io/docs/reference/node/node-status/#info
phase string
NodePhase is the recently observed lifecycle phase of the node. More info: https://kubernetes.io/docs/concepts/nodes/node/#phase The field is never populated, and now is deprecated.
Possible enum values: - `"Pending"` means the node has been created/added by the system, but not configured. - `"Running"` means the node has been configured and has Kubernetes components running. - `"Terminated"` means the node has been removed from the cluster.
List of attachable volumes in use (mounted) by the node.
NodeList
NodeList is the whole list of all Nodes which have been registered with master.

Last time the condition transit from one status to another.
message string
Human readable message indicating details about last transition.
reason string
(brief) reason for the condition's last transition.
status* string
Status of the condition, one of True, False, Unknown.
type* string
Type of node condition.
NodeConfigSource
NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22
Active reports the checkpointed config the node is actively using. Active will represent either the current version of the Assigned config, or the current LastKnownGood config, depending on whether attempting to use the Assigned config results in an error.
Assigned reports the checkpointed config the node will try to use. When Node.Spec.ConfigSource is updated, the node checkpoints the associated config payload to local disk, along with a record indicating intended config. The node refers to this record to choose its config checkpoint, and reports this record in Assigned. Assigned only updates in the status after the record has been checkpointed to disk. When the Kubelet is restarted, it tries to make the Assigned config the Active config by loading and validating the checkpointed payload identified by Assigned.
error string
Error describes any problems reconciling the Spec.ConfigSource to the Active config. Errors may occur, for example, attempting to checkpoint Spec.ConfigSource to the local Assigned record, attempting to checkpoint the payload associated with Spec.ConfigSource, attempting to load or validate the Assigned config, etc. Errors may occur at different points while syncing config. Earlier errors (e.g. download or checkpointing errors) will not result in a rollback to LastKnownGood, and may resolve across Kubelet retries. Later errors (e.g. loading or validating a checkpointed config) will result in a rollback to LastKnownGood. In the latter case, it is usually possible to resolve the error by fixing the config assigned in Spec.ConfigSource. You can find additional information for debugging by searching the error message in the Kubelet log. Error is a human-readable description of the error state; machines can check whether or not Error is empty, but should not rely on the stability of the Error text across Kubelet versions.
LastKnownGood reports the checkpointed config the node will fall back to when it encounters an error attempting to use the Assigned config. The Assigned config becomes the LastKnownGood config when the node determines that the Assigned config is stable and correct. This is currently implemented as a 10-minute soak period starting when the local record of Assigned config is updated. If the Assigned config is Active at the end of this period, it becomes the LastKnownGood. Note that if Spec.ConfigSource is reset to nil (use local defaults), the LastKnownGood is also immediately reset to nil, because the local default config is always assumed good. You should not make assumptions about the node's method of determining config stability and correctness, as this may change or become configurable in the future.
NodeDaemonEndpoints
NodeDaemonEndpoints lists ports opened by daemons running on the Node.
NodeFeatures describes the set of features implemented by the CRI implementation. The features contained in the NodeFeatures should depend only on the cri implementation independent of runtime handlers.
Field
Description

SupplementalGroupsPolicy is set to true if the runtime supports SupplementalGroupsPolicy and ContainerUser.
NodeRuntimeHandler
NodeRuntimeHandler is a set of runtime handler information.
NodeSystemInfo is a set of ids/uuids to uniquely identify the node.
Field
Description
architecture* string
The Architecture reported by the node
bootID* string
Boot ID reported by the node.
containerRuntimeVersion* string
ContainerRuntime Version reported by the node through runtime remote API (e.g. containerd://1.4.2).
kernelVersion* string
Kernel Version reported by the node from 'uname -r' (e.g. 3.16.0-0.bpo.4-amd64).
kubeProxyVersion* string
Deprecated: KubeProxy Version reported by the node.
kubeletVersion* string
Kubelet Version reported by the node.
machineID* string
MachineID reported by the node. For unique machine identification in the cluster this field is preferred. Learn more from man(5) machine-id: http://man7.org/linux/man-pages/man5/machine-id.5.html
operatingSystem* string
The Operating System reported by the node
osImage* string
OS Image reported by the node from /etc/os-release (e.g. Debian GNU/Linux 7 (wheezy)).
SystemUUID reported by the node. For unique machine identification MachineID is preferred. This field is specific to Red Hat hosts https://access.redhat.com/documentation/en-us/red_hat_subscription_management/1/html/rhsm/uuid
Taint
The node this Taint is attached to has the "effect" on any pod that does not tolerate the Taint.
Field
Description
effect* string
Required. The effect of the taint on pods that do not tolerate the taint. Valid effects are NoSchedule, PreferNoSchedule and NoExecute.
Possible enum values: - `"NoExecute"` Evict any already-running pods that do not tolerate the taint. Currently enforced by NodeController. - `"NoSchedule"` Do not allow new pods to schedule onto the node unless they tolerate the taint, but allow all pods submitted to Kubelet without going through the scheduler to start, and allow all already-running pods to continue running. Enforced by the scheduler. - `"PreferNoSchedule"` Like TaintEffectNoSchedule, but the scheduler tries not to schedule new pods onto the node, rather than prohibiting new pods from scheduling onto the node entirely. Enforced by the scheduler.
TimeAdded represents the time at which the taint was added.
value string
The taint value corresponding to the taint key.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string

labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results.

The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.

If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).

PersistentVolumeClaim is a user's request for and claim to a persistent volume
apiVersion: v1
import "k8s.io/api/core/v1"
PersistentVolumeClaim
PersistentVolumeClaim is a user's request for and claim to a persistent volume
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
spec defines the desired characteristics of a volume requested by a pod author. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims
status represents the current information/status of a persistent volume claim. Read-only. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims
PersistentVolumeClaimSpec
PersistentVolumeClaimSpec describes the common attributes of storage devices and allows a Source for provider-specific attributes
Field
Description
accessModes string array
accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.
dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
resources represents the minimum resources the volume should have. Users are allowed to specify resource requirements that are lower than previous value but must still be higher than capacity recorded in the status field of the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources
selector is a label query over volumes to consider for binding.
storageClassName string
storageClassName is the name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1
volumeAttributesClassName string
volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string or nil value indicates that no VolumeAttributesClass will be applied to the claim. If the claim enters an Infeasible error state, this field can be reset to its previous value (including nil) to cancel the modification. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/
volumeMode string
volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec.
Possible enum values: - `"Block"` means the volume will not be formatted with a filesystem and will remain a raw block device. - `"Filesystem"` means the volume will be or is formatted with a filesystem.
volumeName string
volumeName is the binding reference to the PersistentVolume backing this claim.
PersistentVolumeClaimStatus
PersistentVolumeClaimStatus is the current status of a persistent volume claim.
Field
Description
accessModes string array
accessModes contains the actual access modes the volume backing the PVC has. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
allocatedResourceStatuses object
allocatedResourceStatuses stores status of resource being resized for the given PVC. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used. ClaimResourceStatus can be in any of following states: - ControllerResizeInProgress: State set when resize controller starts resizing the volume in control-plane. - ControllerResizeFailed: State set when resize has failed in resize controller with a terminal error. - NodeResizePending: State set when resize controller has finished resizing the volume but further resizing of volume is needed on the node. - NodeResizeInProgress: State set when kubelet starts resizing the volume. - NodeResizeFailed: State set when resizing has failed in kubelet with a terminal error. Transient errors don't set NodeResizeFailed. For example: if expanding a PVC for more capacity - this field can be one of the following states: - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed" When this field is not set, it means that no resize operation is in progress for the given PVC. A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.
allocatedResources object
allocatedResources tracks the resources allocated to a PVC including its capacity. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used. Capacity reported here may be larger than the actual capacity when a volume expansion operation is requested. For storage quota, the larger value from allocatedResources and PVC.spec.resources is used. If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation. If a volume expansion capacity request is lowered, allocatedResources is only lowered if there are no expansion operations in progress and if the actual volume capacity is equal or lower than the requested capacity. A controller that receives PVC update with previously unknown resourceName should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC.
capacity object
capacity represents the actual resources of the underlying volume.
conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'Resizing'.
currentVolumeAttributesClassName string
currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using. When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim
ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted.
phase string
phase represents the current phase of PersistentVolumeClaim.
Possible enum values: - `"Bound"` used for PersistentVolumeClaims that are bound - `"Lost"` used for PersistentVolumeClaims that lost their underlying PersistentVolume. The claim was bound to a PersistentVolume and this volume does not exist any longer and all data on it was lost. - `"Pending"` used for PersistentVolumeClaims that are not yet bound
PersistentVolumeClaimList
PersistentVolumeClaimList is a list of PersistentVolumeClaim items.

Standard list metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
ModifyVolumeStatus
ModifyVolumeStatus represents the status object of ControllerModifyVolume operation
Field
Description
status* string
status is the status of the ControllerModifyVolume operation. It can be in any of following states: - Pending Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing. - InProgress InProgress indicates that the volume is being modified. - Infeasible Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified. Note: New statuses can be added in the future. Consumers should check for unknown statuses and fail appropriately.
Possible enum values: - `"InProgress"` InProgress indicates that the volume is being modified - `"Infeasible"` Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified - `"Pending"` Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing
targetVolumeAttributesClassName string

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

Pod
Pod is a collection of containers that can run on a host. This resource is created by clients and scheduled onto hosts.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Specification of the desired behavior of the pod. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
Most recently observed status of the pod. This data may not be up to date. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
PodSpec
PodSpec is a description of a pod.
Field
Description
activeDeadlineSeconds integer
Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer.
AutomountServiceAccountToken indicates whether a service account token should be automatically mounted.
containers* Container array patch strategy: merge on key name
List of containers belonging to the pod. Containers cannot currently be added or removed. There must be at least one container in a Pod. Cannot be updated.
Specifies the DNS parameters of a pod. Parameters specified here will be merged to the generated DNS configuration based on DNSPolicy.
dnsPolicy string
Set DNS policy for the pod. Defaults to "ClusterFirst". Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'. DNS parameters given in DNSConfig will be merged with the policy selected with DNSPolicy. To have DNS options set along with hostNetwork, you have to specify DNS policy explicitly to 'ClusterFirstWithHostNet'.
Possible enum values: - `"ClusterFirst"` indicates that the pod should use cluster DNS first unless hostNetwork is true, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - `"ClusterFirstWithHostNet"` indicates that the pod should use cluster DNS first, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - `"Default"` indicates that the pod should use the default (as determined by kubelet) DNS settings. - `"None"` indicates that the pod should use empty DNS settings. DNS parameters such as nameservers and search paths should be defined via DNSConfig.
enableServiceLinks boolean
EnableServiceLinks indicates whether information about services should be injected into pod's environment variables, matching the syntax of Docker links. Optional: Defaults to true.
List of ephemeral containers run in this pod. Ephemeral containers may be run in an existing pod to perform user-initiated actions such as debugging. This list cannot be specified when creating a pod, and it cannot be modified by updating the pod spec. In order to add an ephemeral container to an existing pod, use the pod's ephemeralcontainers subresource.
HostAliases is an optional list of hosts and IPs that will be injected into the pod's hosts file if specified.
hostIPC boolean
Use the host's ipc namespace. Optional: Default to false.
hostNetwork boolean
Host networking requested for this pod. Use the host's network namespace. When using HostNetwork you should specify ports so the scheduler is aware. When `hostNetwork` is true, specified `hostPort` fields in port definitions must match `containerPort`, and unspecified `hostPort` fields in port definitions are defaulted to match `containerPort`. Default to false.
hostPID boolean
Use the host's pid namespace. Optional: Default to false.
hostUsers boolean
Use the host's user namespace. Optional: Default to true. If set to true or not present, the pod will be run in the host user namespace, useful for when the pod needs a feature only available to the host user namespace, such as loading a kernel module with CAP_SYS_MODULE. When set to false, a new userns is created for the pod. Setting false is useful for mitigating container breakout vulnerabilities even allowing users to run their containers as root without actually having root privileges on the host.
hostname string
Specifies the hostname of the Pod If not specified, the pod's hostname will be set to a system-defined value.
hostnameOverride string
HostnameOverride specifies an explicit override for the pod's hostname as perceived by the pod. This field only specifies the pod's hostname and does not affect its DNS records. When this field is set to a non-empty string: - It takes precedence over the values set in `hostname` and `subdomain`. - The Pod's hostname will be set to this value. - `setHostnameAsFQDN` must be nil or set to false. - `hostNetwork` must be set to false. This field must be a valid DNS subdomain as defined in RFC 1123 and contain at most 64 characters. Requires the HostnameOverride feature gate to be enabled.
ImagePullSecrets is an optional list of references to secrets in the same namespace to use for pulling any of the images used by this PodSpec. If specified, these secrets will be passed to individual puller implementations for them to use. More info: https://kubernetes.io/docs/concepts/containers/images#specifying-imagepullsecrets-on-a-pod
initContainers Container array patch strategy: merge on key name
List of initialization containers belonging to the pod. Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/
nodeName string
NodeName indicates in which node this pod is scheduled. If empty, this pod is a candidate for scheduling by the scheduler defined in schedulerName. Once this field is set, the kubelet for this node becomes responsible for the lifecycle of this pod. This field should not be used to express a desire for the pod to be scheduled on a specific node. https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodename
nodeSelector object
NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/
Specifies the OS of the containers in the pod. Some pod and container fields are restricted if this is set. If the OS field is set to linux, the following fields must be unset: -securityContext.windowsOptions If the OS field is set to windows, following fields must be unset: - spec.hostPID - spec.hostIPC - spec.hostUsers - spec.resources - spec.securityContext.appArmorProfile - spec.securityContext.seLinuxOptions - spec.securityContext.seccompProfile - spec.securityContext.fsGroup - spec.securityContext.fsGroupChangePolicy - spec.securityContext.sysctls - spec.shareProcessNamespace - spec.securityContext.runAsUser - spec.securityContext.runAsGroup - spec.securityContext.supplementalGroups - spec.securityContext.supplementalGroupsPolicy - spec.containers[*].securityContext.appArmorProfile - spec.containers[*].securityContext.seLinuxOptions - spec.containers[*].securityContext.seccompProfile - spec.containers[*].securityContext.capabilities - spec.containers[*].securityContext.readOnlyRootFilesystem - spec.containers[*].securityContext.privileged - spec.containers[*].securityContext.allowPrivilegeEscalation - spec.containers[*].securityContext.procMount - spec.containers[*].securityContext.runAsUser - spec.containers[*].securityContext.runAsGroup
overhead object
Overhead represents the resource overhead associated with running a pod for a given RuntimeClass. This field will be autopopulated at admission time by the RuntimeClass admission controller. If the RuntimeClass admission controller is enabled, overhead must not be set in Pod create requests. The RuntimeClass admission controller will reject Pod create requests which have the overhead already set. If RuntimeClass is configured and selected in the PodSpec, Overhead will be set to the value defined in the corresponding RuntimeClass, otherwise it will remain unset and treated as zero. More info: https://git.k8s.io/enhancements/keps/sig-node/688-pod-overhead/README.md
preemptionPolicy string
PreemptionPolicy is the Policy for preempting pods with lower priority. One of Never, PreemptLowerPriority. Defaults to PreemptLowerPriority if unset.
Possible enum values: - `"Never"` means that pod never preempts other pods with lower priority. - `"PreemptLowerPriority"` means that pod can preempt other pods with lower priority.
priority integer
The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.
priorityClassName string
If specified, indicates the pod's priority. "system-node-critical" and "system-cluster-critical" are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.
If specified, all readiness gates will be evaluated for pod readiness. A pod is ready when all its containers are ready AND all conditions specified in the readiness gates have status equal to "True" More info: https://git.k8s.io/enhancements/keps/sig-network/580-pod-readiness-gates
ResourceClaims defines which ResourceClaims must be allocated and reserved before the Pod is allowed to start. The resources will be made available to those containers which consume them by name. This is a stable field but requires that the DynamicResourceAllocation feature gate is enabled. This field is immutable.
Resources is the total amount of CPU and Memory resources required by all containers in the pod. It supports specifying Requests and Limits for "cpu", "memory" and "hugepages-" resource names only. ResourceClaims are not supported. This field enables fine-grained control over resource allocation for the entire pod, allowing resource sharing among containers in a pod. This is an alpha field and requires enabling the PodLevelResources feature gate.
restartPolicy string
Restart policy for all containers within the pod. One of Always, OnFailure, Never. In some contexts, only a subset of those values may be permitted. Default to Always. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#restart-policy
Possible enum values: - `"Always"` - `"Never"` - `"OnFailure"`
runtimeClassName string
RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/585-runtime-class
schedulerName string
If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler.
SchedulingGates is an opaque list of values that if specified will block scheduling the pod. If schedulingGates is not empty, the pod will stay in the SchedulingGated state and the scheduler will not attempt to schedule the pod. SchedulingGates can only be set at pod creation time, and be removed only afterwards.
SchedulingGroup provides a reference to the immediate scheduling runtime grouping object that this Pod belongs to. This field is used by the scheduler to identify the group and apply the correct group scheduling policies. The association with a group also impacts other lifecycle aspects of a Pod that are relevant in a wider context of scheduling like preemption, resource attachment, etc. If not specified, the Pod is treated as a single unit in all of these aspects. The group object referenced by this field may not exist at the time the Pod is created. This field is immutable, but a group object with the same name may be recreated with different policies. Doing this during pod scheduling may result in the placement not conforming to the expected policies.
SecurityContext holds pod-level security attributes and common container settings. Optional: Defaults to empty. See type description for default values of each field.
serviceAccount string
DeprecatedServiceAccount is a deprecated alias for ServiceAccountName. Deprecated: Use serviceAccountName instead.
serviceAccountName string
ServiceAccountName is the name of the ServiceAccount to use to run this pod. More info: https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/
setHostnameAsFQDN boolean
If true the pod's hostname will be configured as the pod's FQDN, rather than the leaf name (the default). In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters to FQDN. If a pod does not have FQDN, this has no effect. Default to false.
shareProcessNamespace boolean
Share a single process namespace between all of the containers in a pod. When this is set containers will be able to view and signal processes from other containers in the same pod, and the first process in each container will not be assigned PID 1. HostPID and ShareProcessNamespace cannot both be set. Optional: Default to false.
subdomain string
If specified, the fully qualified Pod hostname will be "\.\.\.svc.\". If not specified, the pod will not have a domainname at all.
terminationGracePeriodSeconds integer
Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. Defaults to 30 seconds.
TopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed.

Examples include "cpu", "memory", "ephemeral-storage", and hugepages.
nominatedNodeName string
nominatedNodeName is set only when this pod preempts other pods on the node, but it cannot be scheduled right away as preemption victims receive their graceful termination periods. This field does not guarantee that the pod will be scheduled on this node. Scheduler may decide to place the pod elsewhere if other nodes become available sooner. Scheduler may also decide to give the resources on this node to a higher priority pod that is created after preemption. As a result, this field may be different than PodSpec.nodeName when the pod is scheduled.
observedGeneration integer
If set, this represents the .metadata.generation that the pod status was set based upon. The PodObservedGenerationTracking feature gate must be enabled to use this field.
phase string
The phase of a Pod is a simple, high-level summary of where the Pod is in its lifecycle. The conditions array, the reason and message fields, and the individual container status arrays contain more detail about the pod's status. There are five possible phase values: Pending: The pod has been accepted by the Kubernetes system, but one or more of the container images has not been created. This includes time before being scheduled as well as time spent downloading images over the network, which could take a while. Running: The pod has been bound to a node, and all of the containers have been created. At least one container is still running, or is in the process of starting or restarting. Succeeded: All containers in the pod have terminated in success, and will not be restarted. Failed: All containers in the pod have terminated, and at least one container has terminated in failure. The container either exited with non-zero status or was terminated by the system. Unknown: For some reason the state of the pod could not be obtained, typically due to an error in communicating with the host of the pod. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#pod-phase
Possible enum values: - `"Failed"` means that all containers in the pod have terminated, and at least one container has terminated in a failure (exited with a non-zero exit code or was stopped by the system). - `"Pending"` means the pod has been accepted by the system, but one or more of the containers has not been started. This includes time before being bound to a node, as well as time spent pulling images onto the host. - `"Running"` means the pod has been bound to a node and all of the containers have been started. At least one container is still running or is in the process of being restarted. - `"Succeeded"` means that all containers in the pod have voluntarily terminated with a container exit code of 0, and the system is not going to restart any of these containers. - `"Unknown"` means that for some reason the state of the pod could not be obtained, typically due to an error in communicating with the host of the pod. Deprecated: It isn't being set since 2015 (74da3b14b0c0f658b3bb8d2def5094686d0e9095)

resize string
Status of resources resize desired for pod's containers. It is empty if no resources resize is pending. Any changes to container resources will automatically set this to "Proposed" Deprecated: Resize status is moved to two pod conditions PodResizePending and PodResizeInProgress. PodResizePending will track states where the spec has been resized, but the Kubelet has not yet allocated the resources. PodResizeInProgress will track in-progress resizes, and should be present whenever allocated resources != acknowledged resources.
resourceClaimStatuses PodResourceClaimStatus array patch strategy: merge,retainKeys on key name
Resources represents the compute resource requests and limits that have been applied at the pod level if pod-level requests or limits are set in PodSpec.Resources

RestartPolicy defines the restart behavior of individual containers in a pod. This overrides the pod-level restart policy. When this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Additionally, setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed.
Represents a list of rules to be checked to determine if the container should be restarted on exit. The rules are evaluated in order. Once a rule matches a container exit condition, the remaining rules are ignored. If no rule matches the container exit condition, the Container-level restart policy determines the whether the container is restarted or not. Constraints on the rules: - At most 20 rules are allowed. - Rules can have the same action. - Identical rules are not forbidden in validations. When rules are specified, container MUST set RestartPolicy explicitly even it if matches the Pod's RestartPolicy.
SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/
StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes
stdin boolean
Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false.
stdinOnce boolean
Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false

The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated.
terminationMessagePolicy string
Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated.
Possible enum values: - `"FallbackToLogsOnError"` will read the most recent contents of the container logs for the container status message when the container exits with an error and the terminationMessagePath has no contents. - `"File"` is the default behavior and will set the container status message to the contents of the container's terminationMessagePath when the container exits.

stdinOnce boolean
Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false

Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated.
terminationMessagePolicy string
Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure.

The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be `\-\` where `\` is the name from the `PodSpec.Volumes` array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long). An existing PVC with that name that is not owned by the pod will *not* be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil.

Lifecycle describes actions that the management system should take in response to container lifecycle events. For the PostStart and PreStop lifecycle handlers, management of the container blocks until the action is complete, unless the container process fails, in which case the handler is aborted.
PostStart is called immediately after a container is created. If the handler fails, the container is terminated and restarted according to its restart policy. Other management of the container blocks until the hook completes. More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks
PreStop is called immediately before a container is terminated due to an API request or management event such as liveness/startup probe failure, preemption, resource contention, etc. The handler is not called if the container crashes or exits. The Pod's termination grace period countdown begins before the PreStop hook is executed. Regardless of the outcome of the handler, the container will eventually terminate within the Pod's termination grace period (unless delayed by finalizers). Other management of the container blocks until the hook completes or until the termination grace period is reached.

The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling affinity expressions, etc.), compute a sum by iterating through the elements of this field and adding "weight" to the sum if the node matches the corresponding matchExpressions; the node(s) with the highest sum are the most preferred.
If the affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the affinity requirements specified by this field cease to be met at some point during pod execution (e.g. due to an update), the system may or may not try to eventually evict the pod from its node.

When there are multiple elements, the lists of nodes corresponding to each podAffinityTerm are intersected, i.e. all terms must be satisfied.
PodAffinityTerm
Defines a set of pods (namely those matching the labelSelector relative to the given namespace(s)) that this pod should be co-located (affinity) or not co-located (anti-affinity) with, where co-located is defined as running on a node whose value of the label with key <topologyKey> matches that of any node on which a pod of the set of pods is running
A label query over a set of resources, in this case pods. If it's null, this PodAffinityTerm matches with no Pods.
matchLabelKeys string array
MatchLabelKeys is a set of pod label keys to select which pods will be taken into consideration. The keys are used to lookup values from the incoming pod labels, those key-value labels are merged with `labelSelector` as `key in (value)` to select the group of existing pods which pods will be taken into consideration for the incoming pod's pod (anti) affinity. Keys that don't exist in the incoming pod labels will be ignored. The default value is empty. The same key is forbidden to exist in both matchLabelKeys and labelSelector. Also, matchLabelKeys cannot be set when labelSelector isn't set.
mismatchLabelKeys string array
MismatchLabelKeys is a set of pod label keys to select which pods will be taken into consideration. The keys are used to lookup values from the incoming pod labels, those key-value labels are merged with `labelSelector` as `key notin (value)` to select the group of existing pods which pods will be taken into consideration for the incoming pod's pod (anti) affinity. Keys that don't exist in the incoming pod labels will be ignored. The default value is empty. The same key is forbidden to exist in both mismatchLabelKeys and labelSelector. Also, mismatchLabelKeys cannot be set when labelSelector isn't set.
A label query over the set of namespaces that the term applies to. The term is applied to the union of the namespaces selected by this field and the ones listed in the namespaces field. null selector and null or empty namespaces list means "this pod's namespace". An empty selector ({}) matches all namespaces.
namespaces string array
namespaces specifies a static list of namespace names that the term applies to. The term is applied to the union of the namespaces listed in this field and the ones selected by namespaceSelector. null or empty namespaces list and null namespaceSelector means "this pod's namespace".
topologyKey* string
This pod should be co-located (affinity) or not co-located (anti-affinity) with the pods matching the labelSelector in the specified namespaces, where co-located is defined as running on a node whose value of the label with key topologyKey matches that of any node on which any of the selected pods is running. Empty topologyKey is not allowed.
PodAntiAffinity
Pod anti affinity is a group of inter pod anti affinity scheduling rules.
The scheduler will prefer to schedule pods to nodes that satisfy the anti-affinity expressions specified by this field, but it may choose a node that violates one or more of the expressions. The node that is most preferred is the one with the greatest sum of weights, i.e. for each node that meets all of the scheduling requirements (resource request, requiredDuringScheduling anti-affinity expressions, etc.), compute a sum by iterating through the elements of this field and subtracting "weight" from the sum if the node has pods which matches the corresponding podAffinityTerm; the node(s) with the highest sum are the most preferred.
If the anti-affinity requirements specified by this field are not met at scheduling time, the pod will not be scheduled onto the node. If the anti-affinity requirements specified by this field cease to be met at some point during pod execution (e.g. due to a pod label update), the system may or may not try to eventually evict the pod from its node. When there are multiple elements, the lists of nodes corresponding to each podAffinityTerm are intersected, i.e. all terms must be satisfied.
PodCertificateProjection
PodCertificateProjection provides a private key and X.509 certificate in the pod filesystem.
Field
Description
certificateChainPath string
Write the certificate chain at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation.
credentialBundlePath string
Write the credential bundle at this path in the projected volume. The credential bundle is a single file that contains multiple PEM blocks. The first PEM block is a PRIVATE KEY block, containing a PKCS#8 private key. The remaining blocks are CERTIFICATE blocks, containing the issued certificate chain from the signer (leaf and any intermediates). Using credentialBundlePath lets your Pod's application code make a single atomic read that retrieves a consistent key and certificate chain. If you project them to separate files, your application code will need to additionally check that the leaf certificate was issued to the key.
keyPath string
Write the key at this path in the projected volume. Most applications should use credentialBundlePath. When using keyPath and certificateChainPath, your application needs to check that the key and leaf certificate are consistent, because it is possible to read the files mid-rotation.
keyType* string
The type of keypair Kubelet will generate for the pod. Valid values are "RSA3072", "RSA4096", "ECDSAP256", "ECDSAP384", "ECDSAP521", and "ED25519".
maxExpirationSeconds integer
maxExpirationSeconds is the maximum lifetime permitted for the certificate. Kubelet copies this value verbatim into the PodCertificateRequests it generates for this projection. If omitted, kube-apiserver will set it to 86400(24 hours). kube-apiserver will reject values shorter than 3600 (1 hour). The maximum allowable value is 7862400 (91 days). The signer implementation is then free to issue a certificate with any lifetime *shorter* than MaxExpirationSeconds, but no shorter than 3600 seconds (1 hour). This constraint is enforced by kube-apiserver. `kubernetes.io` signers will never issue certificates with a lifetime longer than 24 hours.
signerName* string
Kubelet's generated CSRs will be addressed to this signer.
userAnnotations object
userAnnotations allow pod authors to pass additional information to the signer implementation. Kubernetes does not restrict or validate this metadata in any way. These values are copied verbatim into the `spec.unverifiedUserAnnotations` field of the PodCertificateRequest objects that Kubelet creates. Entries are subject to the same validation as object metadata annotations, with the addition that all keys must be domain-prefixed. No restrictions are placed on values, except an overall size limitation on the entire field. Signers should document the keys and values they support. Signers should deny requests that contain keys they do not recognize.
PodCondition
PodCondition contains details for the current condition of this pod.
Last time the condition transitioned from one status to another.
message string
Human-readable message indicating details about last transition.
observedGeneration integer
If set, this represents the .metadata.generation that the pod condition was set based upon.
reason string
Unique, one-word, CamelCase reason for the condition's last transition.

Status is the status of the condition. Can be True, False, Unknown. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#pod-conditions
type* string
Type is the type of the condition. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#pod-conditions
PodDNSConfig

nameservers string array
A list of DNS name server IP addresses. This will be appended to the base nameservers generated from DNSPolicy. Duplicated nameservers will be removed.
A list of DNS resolver options. This will be merged with the base options generated from DNSPolicy. Duplicated entries will be removed. Resolution options given in Options will override those that appear in the base DNSPolicy.
searches string array
A list of DNS search domains for host-name lookup. This will be appended to the base search paths generated from DNSPolicy. Duplicated search paths will be removed.
PodDNSConfigOption
PodDNSConfigOption defines DNS resolver options of a pod.
Field
Description
name string
Name is this DNS resolver option's name. Required.
value string
Value is this DNS resolver option's value.
PodExtendedResourceClaimStatus
PodExtendedResourceClaimStatus is stored in the PodStatus for the extended resource requests backed by DRA. It stores the generated name for the corresponding special ResourceClaim created by the scheduler.

Additional value may be defined in future and can be one of: https://github.com/opencontainers/runtime-spec/blob/master/config.md#platform-specific-configuration Clients should expect to handle additional values and treat unrecognized values in this field as os: null
PodReadinessGate
PodReadinessGate contains the reference to a pod condition
Field
Description
conditionType* string
ConditionType refers to a condition in the pod's condition list with matching type.
PodResourceClaim
PodResourceClaim references exactly one ResourceClaim, either directly or by naming a ResourceClaimTemplate which is then turned into a ResourceClaim for the pod.
It adds a name to it that uniquely identifies the ResourceClaim inside the Pod. Containers that need access to the ResourceClaim reference it with this name.
When the DRAWorkloadResourceClaims feature gate is enabled and this Pod belongs to a PodGroup, a PodResourceClaim is matched to a PodGroupResourceClaim if all of their fields are equal (Name, ResourceClaimName, and ResourceClaimTemplateName). A matched claim references a single ResourceClaim shared across all Pods in the PodGroup, reserved for the PodGroup in ResourceClaimStatus.ReservedFor rather than for individual Pods.
Field
Description
name* string
Name uniquely identifies this resource claim inside the pod. This must be a DNS_LABEL.
resourceClaimName string
ResourceClaimName is the name of a ResourceClaim object in the same namespace as this pod. Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.
resourceClaimTemplateName string
ResourceClaimTemplateName is the name of a ResourceClaimTemplate object in the same namespace as this pod. The template will be used to create a new ResourceClaim, which will be bound to this pod. When this pod is deleted, the ResourceClaim will also be deleted. The pod name and resource name, along with a generated component, will be used to form a unique name for the ResourceClaim, which will be recorded in pod.status.resourceClaimStatuses. When the DRAWorkloadResourceClaims feature gate is enabled and the pod belongs to a PodGroup that defines a PodGroupResourceClaim with the same Name and ResourceClaimTemplateName, this PodResourceClaim resolves to the ResourceClaim generated for the PodGroup. All pods in the group that define an equivalent PodResourceClaim matching the PodGroupResourceClaim's Name and ResourceClaimTemplateName share the same generated ResourceClaim. ResourceClaims generated for a PodGroup are owned by the PodGroup and their lifecycles are tied to the PodGroup instead of any individual pod. This field is immutable and no changes will be made to the corresponding ResourceClaim by the control plane after creating the ResourceClaim. Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.
PodSchedulingGate
PodSchedulingGate is associated to a Pod to guard its scheduling.
Field
Description
name* string
Name of the scheduling gate. Each scheduling gate must have a unique name field.
PodSchedulingGroup
PodSchedulingGroup identifies the runtime scheduling group instance that a Pod belongs to. The scheduler uses this information to apply workload-aware scheduling semantics. Exactly one field must be specified.
Field
Description
podGroupName string
PodGroupName specifies the name of the standalone PodGroup object that represents the runtime instance of this group. Must be a DNS subdomain.
PodSecurityContext
PodSecurityContext holds pod-level security attributes and common container settings. Some fields are also present in container.securityContext. Field values of container.securityContext take precedence over field values of PodSecurityContext.
appArmorProfile is the AppArmor options to use by the containers in this pod. Note that this field cannot be set when spec.os.name is windows.
fsGroup integer
A special supplemental group that applies to all containers in a pod. Some volume types allow the Kubelet to change the ownership of that volume to be owned by the pod: 1. The owning GID will be the FSGroup 2. The setgid bit is set (new files created in the volume will be owned by FSGroup) 3. The permission bits are OR'd with rw-rw---- If unset, the Kubelet will not modify the ownership and permissions of any volume. Note that this field cannot be set when spec.os.name is windows.
fsGroupChangePolicy string
fsGroupChangePolicy defines behavior of changing ownership and permission of the volume before being exposed inside Pod. This field will only apply to volume types which support fsGroup based ownership(and permissions). It will have no effect on ephemeral volume types such as: secret, configmaps and emptydir. Valid values are "OnRootMismatch" and "Always". If not specified, "Always" is used. Note that this field cannot be set when spec.os.name is windows.
Possible enum values: - `"Always"` indicates that volume's ownership and permissions should always be changed whenever volume is mounted inside a Pod. This the default behavior. - `"OnRootMismatch"` indicates that volume's ownership and permissions will be changed only when permission and ownership of root directory does not match with expected permissions on the volume. This can help shorten the time it takes to change ownership and permissions of a volume.
runAsGroup integer
The GID to run the entrypoint of the container process. Uses runtime default if unset. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence for that container. Note that this field cannot be set when spec.os.name is windows.
runAsNonRoot boolean
Indicates that the container must run as a non-root user. If true, the Kubelet will validate the image at runtime to ensure that it does not run as UID 0 (root) and fail to start the container if it does. If unset or false, no such validation will be performed. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.
runAsUser integer
The UID to run the entrypoint of the container process. Defaults to user specified in image metadata if unspecified. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence for that container. Note that this field cannot be set when spec.os.name is windows.
seLinuxChangePolicy string
seLinuxChangePolicy defines how the container's SELinux label is applied to all volumes used by the Pod. It has no effect on nodes that do not support SELinux or to volumes does not support SELinux. Valid values are "MountOption" and "Recursive". "Recursive" means relabeling of all files on all Pod volumes by the container runtime. This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node. "MountOption" mounts all eligible Pod volumes with `-o context` mount option. This requires all Pods that share the same volume to use the same SELinux label. It is not possible to share the same volume among privileged and unprivileged Pods. Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their CSIDriver instance. Other volumes are always re-labelled recursively. "MountOption" value is allowed only when SELinuxMount feature gate is enabled. If not specified and SELinuxMount feature gate is enabled, "MountOption" is used. If not specified and SELinuxMount feature gate is disabled, "MountOption" is used for ReadWriteOncePod volumes and "Recursive" for all other volumes. This field affects only Pods that have SELinux label set, either in PodSecurityContext or in SecurityContext of all containers. All Pods that use the same volume should use the same seLinuxChangePolicy, otherwise some pods can get stuck in ContainerCreating state. Note that this field cannot be set when spec.os.name is windows.
The SELinux context to be applied to all containers. If unspecified, the container runtime will allocate a random SELinux context for each container. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence for that container. Note that this field cannot be set when spec.os.name is windows.
The seccomp options to use by the containers in this pod. Note that this field cannot be set when spec.os.name is windows.
supplementalGroups integer array
A list of groups applied to the first process run in each container, in addition to the container's primary GID and fsGroup (if specified). If the SupplementalGroupsPolicy feature is enabled, the supplementalGroupsPolicy field determines whether these are in addition to or instead of any group memberships defined in the container image. If unspecified, no additional groups are added, though group memberships defined in the container image may still be used, depending on the supplementalGroupsPolicy field. Note that this field cannot be set when spec.os.name is windows.
supplementalGroupsPolicy string
Defines how supplemental groups of the first container processes are calculated. Valid values are "Merge" and "Strict". If not specified, "Merge" is used. (Alpha) Using the field requires the SupplementalGroupsPolicy feature gate to be enabled and the container runtime must implement support for this feature. Note that this field cannot be set when spec.os.name is windows.
Possible enum values: - `"Merge"` means that the container's provided SupplementalGroups and FsGroup (specified in SecurityContext) will be merged with the primary user's groups as defined in the container image (in /etc/group). - `"Strict"` means that the container's provided SupplementalGroups and FsGroup (specified in SecurityContext) will be used instead of any groups defined in the container image.
Sysctls hold a list of namespaced sysctls used for the pod. Pods with unsupported sysctls (by the container runtime) might fail to launch. Note that this field cannot be set when spec.os.name is windows.
The Windows specific settings applied to all containers. If unspecified, the options within a container's SecurityContext will be used. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is linux.
PreferredSchedulingTerm
An empty preferred scheduling term matches all objects with implicit weight 0 (i.e. it's a no-op). A null preferred scheduling term matches no objects (i.e. is also a no-op).

periodSeconds integer
How often (in seconds) to perform the probe. Default to 10 seconds. Minimum value is 1.
successThreshold integer
Minimum consecutive successes for the probe to be considered successful after having failed. Defaults to 1. Must be 1 for liveness and startup. Minimum value is 1.
Optional duration in seconds the pod needs to terminate gracefully upon probe failure. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset.
timeoutSeconds integer
Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

procMount denotes the type of proc mount to use for the containers. The default value is Default which uses the container runtime defaults for readonly paths and masked paths. Note that this field cannot be set when spec.os.name is windows.
Possible enum values: - `"Default"` uses the container runtime defaults for readonly and masked paths for /proc. Most container runtimes mask certain paths in /proc to avoid accidental security exposure of special devices or information. - `"Unmasked"` bypasses the default masking behavior of the container runtime and ensures the newly created /proc the container stays in tact with no modifications.
readOnlyRootFilesystem boolean
Whether this container has a read-only root filesystem. Default is false. Note that this field cannot be set when spec.os.name is windows.
runAsGroup integer
The GID to run the entrypoint of the container process. Uses runtime default if unset. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is windows.
runAsNonRoot boolean
Indicates that the container must run as a non-root user. If true, the Kubelet will validate the image at runtime to ensure that it does not run as UID 0 (root) and fail to start the container if it does. If unset or false, no such validation will be performed. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.
runAsUser integer
The UID to run the entrypoint of the container process. Defaults to user specified in image metadata if unspecified. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is windows.
The SELinux context to be applied to the container. If unspecified, the container runtime will allocate a random SELinux context for each container. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is windows.
The seccomp options to use by this container. If seccomp options are provided at both the pod & container level, the container options override the pod options. Note that this field cannot be set when spec.os.name is windows.
The Windows specific settings applied to all containers. If unspecified, the options from the PodSecurityContext will be used. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is linux.
ServiceAccountTokenProjection
ServiceAccountTokenProjection represents a projected service account token volume. This projection can be used to insert a service account token into the pods runtime filesystem for use against APIs (Kubernetes API Server or otherwise).
Field
Description
audience string
audience is the intended audience of the token. A recipient of a token must identify itself with an identifier specified in the audience of the token, and otherwise should reject the token. The audience defaults to the identifier of the apiserver.
expirationSeconds integer
expirationSeconds is the requested duration of validity of the service account token. As the token approaches expiration, the kubelet volume plugin will proactively rotate the service account token. The kubelet will start trying to rotate the token if the token is older than 80 percent of its time to live or if the token is older than 24 hours.Defaults to 1 hour and must be at least 10 minutes.
path* string
path is the path relative to the mount point of the file to project the token into.
SleepAction
SleepAction describes a "sleep" action.
Field
Description
seconds* integer
Seconds is the number of seconds to sleep.
StorageOSVolumeSource
Represents a StorageOS persistent volume resource.
Field
Description
fsType string
fsType is the filesystem type to mount. Must be a filesystem type supported by the host operating system. Ex. "ext4", "xfs", "ntfs". Implicitly inferred to be "ext4" if unspecified.
readOnly boolean
readOnly defaults to false (read/write). ReadOnly here will force the ReadOnly setting in VolumeMounts.
secretRef specifies the secret to use for obtaining the StorageOS API credentials. If not specified, default values will be attempted.
volumeName string
volumeName is the human-readable name of the StorageOS volume. Volume names are only unique within a namespace.
volumeNamespace string
volumeNamespace specifies the scope of the volume within StorageOS. If no namespace is specified then the Pod's namespace will be used. This allows the Kubernetes name scoping to be mirrored within StorageOS for tighter integration. Set VolumeName to any name to override the default behaviour. Set to "default" if you are not using namespaces within StorageOS. Namespaces that do not pre-exist within StorageOS will be created.
Sysctl
Sysctl defines a kernel parameter to be set
Field
Description
name* string
Name of a property to set
value* string
Value of a property to set
TCPSocketAction
TCPSocketAction describes an action based on opening a socket
Field
Description
host string
Optional: Host name to connect to, defaults to the pod IP.
port*
Number or name of the port to access on the container. Number must be in the range 1 to 65535. Name must be an IANA_SVC_NAME.
TopologySpreadConstraint
TopologySpreadConstraint specifies how to spread matching pods among the given topology.
LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.
matchLabelKeys string array
MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default).
maxSkew* integer
MaxSkew describes the degree to which pods may be unevenly distributed. When `whenUnsatisfiable=DoNotSchedule`, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When `whenUnsatisfiable=ScheduleAnyway`, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed.
minDomains integer
MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew.
nodeAffinityPolicy string
NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy.
Possible enum values: - `"Honor"` means use this scheduling directive when calculating pod topology spread skew. - `"Ignore"` means ignore this scheduling directive when calculating pod topology spread skew.
nodeTaintsPolicy string
NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy.
Possible enum values: - `"Honor"` means use this scheduling directive when calculating pod topology spread skew. - `"Ignore"` means ignore this scheduling directive when calculating pod topology spread skew.
topologyKey* string
TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each \ as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field.
whenUnsatisfiable* string
WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it *more* imbalanced. It's a required field.
Possible enum values: - `"DoNotSchedule"` instructs the scheduler not to schedule the pod when constraints are not satisfied. - `"ScheduleAnyway"` instructs the scheduler to schedule the pod even if constraints are not satisfied.
Volume
Volume represents a named volume in a pod that may be accessed by any container in the pod.
awsElasticBlockStore represents an AWS Disk resource that is attached to a kubelet's host machine and then exposed to the pod. Deprecated: AWSElasticBlockStore is deprecated. All operations for the in-tree awsElasticBlockStore type are redirected to the ebs.csi.aws.com CSI driver. More info: https://kubernetes.io/docs/concepts/storage/volumes#awselasticblockstore
azureDisk represents an Azure Data Disk mount on the host and bind mount to the pod. Deprecated: AzureDisk is deprecated. All operations for the in-tree azureDisk type are redirected to the disk.csi.azure.com CSI driver.
azureFile represents an Azure File Service mount on the host and bind mount to the pod. Deprecated: AzureFile is deprecated. All operations for the in-tree azureFile type are redirected to the file.csi.azure.com CSI driver.
cephFS represents a Ceph FS mount on the host that shares a pod's lifetime. Deprecated: CephFS is deprecated and the in-tree cephfs type is no longer supported.
cinder represents a cinder volume attached and mounted on kubelets host machine. Deprecated: Cinder is deprecated. All operations for the in-tree cinder type are redirected to the cinder.csi.openstack.org CSI driver. More info: https://examples.k8s.io/mysql-cinder-pd/README.md
ephemeral represents a volume that is handled by a cluster storage driver. The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed. Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim). Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod. Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information. A pod can use both types of ephemeral volumes and persistent volumes at the same time.
flexVolume represents a generic volume resource that is provisioned/attached using an exec based plugin. Deprecated: FlexVolume is deprecated. Consider using a CSIDriver instead.
flocker represents a Flocker volume attached to a kubelet's host machine. This depends on the Flocker control service being running. Deprecated: Flocker is deprecated and the in-tree flocker type is no longer supported.
gcePersistentDisk represents a GCE Disk resource that is attached to a kubelet's host machine and then exposed to the pod. Deprecated: GCEPersistentDisk is deprecated. All operations for the in-tree gcePersistentDisk type are redirected to the pd.csi.storage.gke.io CSI driver. More info: https://kubernetes.io/docs/concepts/storage/volumes#gcepersistentdisk
gitRepo represents a git repository at a particular revision. Deprecated: GitRepo is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container.
glusterfs represents a Glusterfs mount on the host that shares a pod's lifetime. Deprecated: Glusterfs is deprecated and the in-tree glusterfs type is no longer supported.
hostPath represents a pre-existing file or directory on the host machine that is directly exposed to the container. This is generally used for system agents or other privileged things that are allowed to see the host machine. Most containers will NOT need this. More info: https://kubernetes.io/docs/concepts/storage/volumes#hostpath
image represents an OCI object (a container image or artifact) pulled and mounted on the kubelet's host machine. The volume is resolved at pod startup depending on which PullPolicy value is provided: - Always: the kubelet always attempts to pull the reference. Container creation will fail If the pull fails. - Never: the kubelet never pulls the reference and only uses a local image or artifact. Container creation will fail if the reference isn't present. - IfNotPresent: the kubelet pulls if the reference isn't already present on disk. Container creation will fail if the reference isn't present and the pull fails. The volume gets re-resolved if the pod gets deleted and recreated, which means that new remote content will become available on pod recreation. A failure to resolve or pull the image during pod startup will block containers from starting and may add significant latency. Failures will be retried using normal volume backoff and will be reported on the pod reason and message. The types of objects that may be mounted by this volume are defined by the container runtime implementation on a host machine and at minimum must include all valid types supported by the container image field. The OCI object gets mounted in a single directory (spec.containers[*].volumeMounts.mountPath) by merging the manifest layers in the same way as for container images. The volume will be mounted read-only (ro). Sub path mounts for containers are not supported (spec.containers[*].volumeMounts.subpath) before 1.33. The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.
iscsi represents an ISCSI Disk resource that is attached to a kubelet's host machine and then exposed to the pod. More info: https://kubernetes.io/docs/concepts/storage/volumes/#iscsi
name* string
name of the volume. Must be a DNS_LABEL and unique within the pod. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names
persistentVolumeClaimVolumeSource represents a reference to a PersistentVolumeClaim in the same namespace. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#persistentvolumeclaims
photonPersistentDisk represents a PhotonController persistent disk attached and mounted on kubelets host machine. Deprecated: PhotonPersistentDisk is deprecated and the in-tree photonPersistentDisk type is no longer supported.

Field
Description
devicePath* string

name* string
name must match the name of a persistentVolumeClaim in the pod
VolumeMount
VolumeMount describes a mounting of a Volume within a container.
Field
Description
mountPath* string
Path within the container at which the volume should be mounted. Must not contain ':'.
mountPropagation string
mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10. When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified (which defaults to None).
Possible enum values: - `"Bidirectional"` means that the volume in a container will receive new mounts from the host or other containers, and its own mounts will be propagated from the container to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rshared" in Linux terminology). - `"HostToContainer"` means that the volume in a container will receive new mounts from the host or other containers, but filesystems mounted inside the container won't be propagated to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rslave" in Linux terminology). - `"None"` means that the volume in a container will not receive new mounts from the host or other containers, and filesystems mounted inside the container won't be propagated to the host or other containers. Note that this mode corresponds to "private" in Linux terminology.
name* string
This must match the Name of a Volume.
readOnly boolean
Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false.
recursiveReadOnly string
RecursiveReadOnly specifies whether read-only mounts should be handled recursively. If ReadOnly is false, this field has no meaning and must be unspecified. If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason. If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None). If this field is not specified, it is treated as an equivalent of Disabled.
subPath string
Path within the volume from which the container's volume should be mounted. Defaults to "" (volume's root).
subPathExpr string
Expanded path within the volume from which the container's volume should be mounted. Behaves similarly to SubPath but environment variable references $(VAR_NAME) are expanded using the container's environment. Defaults to "" (volume's root). SubPathExpr and SubPath are mutually exclusive.
VolumeProjection
Projection that may be projected along with other supported volume types. Exactly one of these fields must be set.
ClusterTrustBundle allows a pod to access the `.spec.trustBundle` field of ClusterTrustBundle objects in an auto-updating file. Alpha, gated by the ClusterTrustBundleProjection feature gate. ClusterTrustBundle objects can either be selected by name, or by the combination of signer name and a label selector. Kubelet performs aggressive normalization of the PEM contents written into the pod filesystem. Esoteric PEM features such as inter-block comments and block headers are stripped. Certificates are deduplicated. The ordering of certificates within the file is arbitrary, and Kubelet may change the order over time.
Projects an auto-rotating credential bundle (private key and certificate chain) that the pod can use either as a TLS client or server. Kubelet generates a private key and uses it to send a PodCertificateRequest to the named signer. Once the signer approves the request and issues a certificate chain, Kubelet writes the key and certificate chain to the pod filesystem. The pod does not start until certificates have been issued for each podCertificate projected volume source in its spec. Kubelet will begin trying to rotate the certificate at the time indicated by the signer using the PodCertificateRequest.Status.BeginRefreshAt timestamp. Kubelet can write a single file, indicated by the credentialBundlePath field, or separate files, indicated by the keyPath and certificateChainPath fields. The credential bundle is a single file in PEM format. The first PEM entry is the private key (in PKCS#8 format), and the remaining PEM entries are the certificate chain issued by the signer (typically, signers will return their certificate chain in leaf-to-root order). Prefer using the credential bundle format, since your application code can read it atomically. If you use keyPath and certificateChainPath, your application must make two separate file reads. If these coincide with a certificate rotation, it is possible that the private key and leaf certificate you read may not correspond to each other. Your application will need to check for this condition, and re-read until they are consistent. The named signer controls chooses the format of the certificate it issues; consult the signer implementation's documentation to learn how to use the certificates it issues.
Required. A pod affinity term, associated with the corresponding weight.
weight* integer
weight associated with matching the corresponding podAffinityTerm, in the range 1-100.
WindowsSecurityContextOptions

GMSACredentialSpec is where the GMSA admission webhook (https://github.com/kubernetes-sigs/windows-gmsa) inlines the contents of the GMSA credential spec named by the GMSACredentialSpecName field.
gmsaCredentialSpecName string
GMSACredentialSpecName is the name of the GMSA credential spec to use.
hostProcess boolean
HostProcess determines if a container should be run as a 'Host Process' container. All of a Pod's containers must have the same effective HostProcess value (it is not allowed to have a mix of HostProcess containers and non-HostProcess containers). In addition, if HostProcess is true then HostNetwork must also be set to true.
runAsUserName string
The UserName in Windows to run the entrypoint of the container process. Defaults to the user specified in image metadata if unspecified. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents

Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

object name and auth scope, such as for teams and projects
Query Parameters
Name
Type
Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.

fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force

container
string
The container for which to stream logs. Defaults to only container if there is one container in the pod.
follow
boolean
Follow the log stream of the pod. Defaults to false.
insecureSkipTLSVerifyBackend
boolean
insecureSkipTLSVerifyBackend indicates that the apiserver should not confirm the validity of the serving certificate of the backend it is connecting to. This will make the HTTPS connection between the apiserver and the backend insecure. This means the apiserver cannot verify the log data it is receiving came from the real kubelet. If the kubelet is configured to verify the apiserver's TLS credentials, it does not mean the connection to the real kubelet is vulnerable to a man in the middle attack (e.g. an attacker could not intercept the actual log data coming from the real kubelet).
limitBytes
integer
If set, the number of bytes to read from the server before terminating the log output. This may not display a complete final line of logging, and may return slightly more or slightly less than the specified limit.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
previous
boolean
Return previous terminated container logs. Defaults to false.
sinceSeconds
integer
A relative time in seconds before the current time from which to show logs. If this value precedes the time a pod was started, only logs since the pod start will be returned. If this value is in the future, no logs will be returned. Only one of sinceSeconds or sinceTime may be specified.
stream
string
Specify which container log stream to return to the client. Acceptable values are "All", "Stdout" and "Stderr". If not specified, "All" is used, and both stdout and stderr are returned interleaved. Note that when "TailLines" is specified, "Stream" can only be set to nil or "All".
tailLines
integer
If set, the number of lines from the end of the logs to show. If not specified, logs are shown from the creation of the container or sinceSeconds or sinceTime. Note that when "TailLines" is specified, "Stream" can only be set to nil or "All".
timestamps
boolean
If true, add an RFC3339 or RFC3339Nano timestamp at the beginning of every line of log output. Defaults to false.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

ReplicationController represents the configuration of a replication controller.
apiVersion: v1
import "k8s.io/api/core/v1"
ReplicationController
ReplicationController represents the configuration of a replication controller.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
If the Labels of a ReplicationController are empty, they are defaulted to be the same as the Pod(s) that the replication controller manages. Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Spec defines the specification of the desired behavior of the replication controller. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
Status is the most recently observed status of the replication controller. This data may be out of date by some window of time. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
ReplicationControllerSpec
ReplicationControllerSpec is the specification of a replication controller.
Field
Description
minReadySeconds integer
Minimum number of seconds for which a newly created pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)
replicas integer
Replicas is the number of desired replicas. This is a pointer to distinguish between explicit zero and unspecified. Defaults to 1. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#what-is-a-replicationcontroller
selector object
Selector is a label query over pods that should match the Replicas count. If Selector is empty, it is defaulted to the labels present on the Pod template. Label keys and values that must match in order to be controlled by this replication controller, if empty defaulted to labels on Pod template.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.

This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string

The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Query Parameters
Name

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.

shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid").

pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint. This field is required for apply requests (application/apply-patch) but optional for non-apply patch types (JsonPatch, MergePatch, StrategicMergePatch).
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.
force
boolean
Force is going to "force" Apply requests. It means user will re-acquire conflicting fields owned by other people. Force flag must be unset for non-apply patch requests.

Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
data object
Data contains the secret data. Each key must consist of alphanumeric characters, '-', '_' or '.'. The serialized form of the secret data is a base64 encoded string, representing the arbitrary (possibly non-string) data value here. Described in https://tools.ietf.org/html/rfc4648#section-4
immutable boolean
Immutable, if set to true, ensures that data stored in the Secret cannot be updated (only object metadata can be modified). If not set to true, the field can be modified at any time. Defaulted to nil.
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
stringData object
stringData allows specifying non-binary secret data in string form. It is provided as a write-only input field for convenience. All keys and values are merged into the data field on write, overwriting any existing values. The stringData field is never output when reading from the API.
type string
Used to facilitate programmatic handling of secret data. More info: https://kubernetes.io/docs/concepts/configuration/secret/#secret-types
SecretList
SecretList is a list of Secret.

Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldManager
string
fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint.
fieldValidation
string
fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered.

dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds

The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.

WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string

The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string

Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.

Description
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token.

Service
Service is a named abstraction of software service (for example, mysql) consisting of local port (for example 3306) that the proxy listens on, and the selector that determines which pods will answer requests sent through the proxy.
Field
Description
apiVersion string
APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind string
Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
Most recently observed status of the service. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status
ServiceSpec
ServiceSpec describes the attributes that a user creates on a service.
Field
Description
allocateLoadBalancerNodePorts boolean
allocateLoadBalancerNodePorts defines if NodePorts will be automatically allocated for services with type LoadBalancer. Default is "true". It may be set to "false" if the cluster load-balancer does not rely on NodePorts. If the caller requests specific NodePorts (by specifying a value), those requests will be respected, regardless of this field. This field may only be set for services with type LoadBalancer and will be cleared if the type is changed to any other type.
clusterIP string
clusterIP is the IP address of the service and is usually assigned randomly. If an address is specified manually, is in-range (as per system configuration), and is not in use, it will be allocated to the service; otherwise creation of the service will fail. This field may not be changed through updates unless the type field is also being changed to ExternalName (which requires this field to be blank) or the type field is being changed from ExternalName (in which case this field may optionally be specified, as describe above). Valid values are "None", empty string (""), or a valid IP address. Setting this to "None" makes a "headless service" (no virtual IP), which is useful when direct endpoint connections are preferred and proxying is not required. Only applies to types ClusterIP, NodePort, and LoadBalancer. If this field is specified when creating a Service of type ExternalName, creation will fail. This field will be wiped when updating a Service to type ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies
clusterIPs string array
ClusterIPs is a list of IP addresses assigned to this service, and are usually assigned randomly. If an address is specified manually, is in-range (as per system configuration), and is not in use, it will be allocated to the service; otherwise creation of the service will fail. This field may not be changed through updates unless the type field is also being changed to ExternalName (which requires this field to be empty) or the type field is being changed from ExternalName (in which case this field may optionally be specified, as describe above). Valid values are "None", empty string (""), or a valid IP address. Setting this to "None" makes a "headless service" (no virtual IP), which is useful when direct endpoint connections are preferred and proxying is not required. Only applies to types ClusterIP, NodePort, and LoadBalancer. If this field is specified when creating a Service of type ExternalName, creation will fail. This field will be wiped when updating a Service to type ExternalName. If this field is not specified, it will be initialized from the clusterIP field. If this field is specified, clients must ensure that clusterIPs[0] and clusterIP have the same value. This field may hold a maximum of two entries (dual-stack IPs, in either order). These IPs must correspond to the values of the ipFamilies field. Both clusterIPs and ipFamilies are governed by the ipFamilyPolicy field. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies
externalIPs string array
externalIPs is a list of IP addresses for which nodes in the cluster will also accept traffic for this service. These IPs are not managed by Kubernetes. The user is responsible for ensuring that traffic arrives at a node with this IP. A common example is external load-balancers that are not part of the Kubernetes system.
externalName string
externalName is the external reference that discovery mechanisms will return as an alias for this service (e.g. a DNS CNAME record). No proxying will be involved. Must be a lowercase RFC-1123 hostname (https://tools.ietf.org/html/rfc1123) and requires `type` to be "ExternalName".
externalTrafficPolicy string
externalTrafficPolicy describes how nodes distribute service traffic they receive on one of the Service's "externally-facing" addresses (NodePorts, ExternalIPs, and LoadBalancer IPs). If set to "Local", the proxy will configure the service in a way that assumes that external load balancers will take care of balancing the service traffic between nodes, and so each node will deliver traffic only to the node-local endpoints of the service, without masquerading the client source IP. (Traffic mistakenly sent to a node with no endpoints will be dropped.) The default value, "Cluster", uses the standard behavior of routing to all endpoints evenly (possibly modified by topology and other features). Note that traffic sent to an External IP or LoadBalancer IP from within the cluster will always get "Cluster" semantics, but clients sending to a NodePort from within the cluster may need to take traffic policy into account when picking a node.
Possible enum values: - `"Cluster"` routes traffic to all endpoints. - `"Local"` preserves the source IP of the traffic by routing only to endpoints on the same node as the traffic was received on (dropping the traffic if there are no local endpoints).
healthCheckNodePort integer
healthCheckNodePort specifies the healthcheck nodePort for the service. This only applies when type is set to LoadBalancer and externalTrafficPolicy is set to Local. If a value is specified, is in-range, and is not in use, it will be used. If not specified, a value will be automatically allocated. External systems (e.g. load-balancers) can use this port to determine if a given node holds endpoints for this service or not. If this field is specified when creating a Service which does not need it, creation will fail. This field will be wiped when updating a Service to no longer need it (e.g. changing type). This field cannot be updated once set.
internalTrafficPolicy string
InternalTrafficPolicy describes how nodes distribute service traffic they receive on the ClusterIP. If set to "Local", the proxy will assume that pods only want to talk to endpoints of the service on the same node as the pod, dropping the traffic if there are no local endpoints. The default value, "Cluster", uses the standard behavior of routing to all endpoints evenly (possibly modified by topology and other features).
Possible enum values: - `"Cluster"` routes traffic to all endpoints. - `"Local"` routes traffic only to endpoints on the same node as the client pod (dropping the traffic if there are no local endpoints).
ipFamilies string array
IPFamilies is a list of IP families (e.g. IPv4, IPv6) assigned to this service. This field is usually assigned automatically based on cluster configuration and the ipFamilyPolicy field. If this field is specified manually, the requested family is available in the cluster, and ipFamilyPolicy allows it, it will be used; otherwise creation of the service will fail. This field is conditionally mutable: it allows for adding or removing a secondary IP family, but it does not allow changing the primary IP family of the Service. Valid values are "IPv4" and "IPv6". This field only applies to Services of types ClusterIP, NodePort, and LoadBalancer, and does apply to "headless" services. This field will be wiped when updating a Service to type ExternalName. This field may hold a maximum of two entries (dual-stack families, in either order). These families must correspond to the values of the clusterIPs field, if specified. Both clusterIPs and ipFamilies are governed by the ipFamilyPolicy field.
ipFamilyPolicy string
IPFamilyPolicy represents the dual-stack-ness requested or required by this Service. If there is no value provided, then this field will be set to SingleStack. Services can be "SingleStack" (a single IP family), "PreferDualStack" (two IP families on dual-stack configured clusters or a single IP family on single-stack clusters), or "RequireDualStack" (two IP families on dual-stack configured clusters, otherwise fail). The ipFamilies and clusterIPs fields depend on the value of this field. This field will be wiped when updating a service to type ExternalName.
Possible enum values: - `"PreferDualStack"` indicates that this service prefers dual-stack when the cluster is configured for dual-stack. If the cluster is not configured for dual-stack the service will be assigned a single IPFamily. If the IPFamily is not set in service.spec.ipFamilies then the service will be assigned the default IPFamily configured on the cluster - `"RequireDualStack"` indicates that this service requires dual-stack. Using IPFamilyPolicyRequireDualStack on a single stack cluster will result in validation errors. The IPFamilies (and their order) assigned to this service is based on service.spec.ipFamilies. If service.spec.ipFamilies was not provided then it will be assigned according to how they are configured on the cluster. If service.spec.ipFamilies has only one entry then the alternative IPFamily will be added by apiserver - `"SingleStack"` indicates that this service is required to have a single IPFamily. The IPFamily assigned is based on the default IPFamily used by the cluster or as identified by service.spec.ipFamilies field
loadBalancerClass string
loadBalancerClass is the class of the load balancer implementation this Service belongs to. If specified, the value of this field must be a label-style identifier, with an optional prefix, e.g. "internal-vip" or "example.com/internal-vip". Unprefixed names are reserved for end-users. This field can only be set when the Service type is 'LoadBalancer'. If not set, the default load balancer implementation is used, today this is typically done through the cloud provider integration, but should apply for any default implementation. If set, it is assumed that a load balancer implementation is watching for Services with a matching class. Any default load balancer implementation (e.g. cloud providers) should ignore Services that set this field. This field can only be set when creating or updating a Service to type 'LoadBalancer'. Once set, it can not be changed. This field will be wiped when a service is updated to a non 'LoadBalancer' type.
loadBalancerIP string
Only applies to Service Type: LoadBalancer. This feature depends on whether the underlying cloud-provider supports specifying the loadBalancerIP when a load balancer is created. This field will be ignored if the cloud-provider does not support the feature. Deprecated: This field was under-specified and its meaning varies across implementations. Using it is non-portable and it may not support dual-stack. Users are encouraged to use implementation-specific annotations when available.
loadBalancerSourceRanges string array
If specified and supported by the platform, this will restrict traffic through the cloud-provider load-balancer will be restricted to the specified client IPs. This field will be ignored if the cloud-provider does not support the feature." More info: https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/
The list of ports that are exposed by this service. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies
publishNotReadyAddresses boolean
publishNotReadyAddresses indicates that any agent which deals with endpoints for this Service should disregard any indications of ready/not-ready. The primary use case for setting this field is for a StatefulSet's Headless Service to propagate SRV DNS records for its Pods for the purpose of peer discovery. The Kubernetes controllers that generate Endpoints and EndpointSlice resources for Services interpret this to mean that all endpoints are considered "ready" even if the Pods themselves are not. Agents which consume only Kubernetes generated endpoints through the Endpoints or EndpointSlice resources can safely assume this behavior.
selector object
Route service traffic to pods with label keys and values matching this selector. If empty or not present, the service is assumed to have an external process managing its endpoints, which Kubernetes will not modify. Only applies to types ClusterIP, NodePort, and LoadBalancer. Ignored if type is ExternalName. More info: https://kubernetes.io/docs/concepts/services-networking/service/
sessionAffinity string
Supports "ClientIP" and "None". Used to maintain session affinity. Enable client IP based session affinity. Must be ClientIP or None. Defaults to None. More info: https://kubernetes.io/docs/concepts/services-networking/service/#virtual-ips-and-service-proxies
Possible enum values: - `"ClientIP"` is the Client IP based. - `"None"` - no session affinity.
sessionAffinityConfig contains the configurations of session affinity.
trafficDistribution string
TrafficDistribution offers a way to express preferences for how traffic is distributed to Service endpoints. Implementations can use this field as a hint, but are not required to guarantee strict adherence. If the field is not set, the implementation will apply its default routing strategy. If set to "PreferClose", implementations should prioritize endpoints that are in the same zone.
type string
type determines how the Service is exposed. Defaults to ClusterIP. Valid options are ExternalName, ClusterIP, NodePort, and LoadBalancer. "ClusterIP" allocates a cluster-internal IP address for load-balancing to endpoints. Endpoints are determined by the selector or if that is not specified, by manual construction of an Endpoints object or EndpointSlice objects. If clusterIP is "None", no virtual IP is allocated and the endpoints are published as a set of endpoints rather than a virtual IP. "NodePort" builds on ClusterIP and allocates a port on every node which routes to the same endpoints as the clusterIP. "LoadBalancer" builds on NodePort and creates an external load-balancer (if supported in the current cloud) which routes to the same endpoints as the clusterIP. "ExternalName" aliases this service to the specified externalName. Several other fields do not apply to ExternalName services. More info: https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types
Possible enum values: - `"ClusterIP"` means a service will only be accessible inside the cluster, via the cluster IP. - `"ExternalName"` means a service consists of only a reference to an external name that kubedns or equivalent will return as a CNAME record, with no exposing or proxying of any pods involved. - `"LoadBalancer"` means a service will be exposed via an external load balancer (if the cloud provider supports it), in addition to 'NodePort' type. - `"NodePort"` means a service will be exposed on one port of every node, in addition to 'ClusterIP' type.

ipMode string
IPMode specifies how the load-balancer IP behaves, and may only be specified when the ip field is specified. Setting this to "VIP" indicates that traffic is delivered to the node with the destination set to the load-balancer's IP and port. Setting this to "Proxy" indicates that traffic is delivered to the node or pod with the destination set to the node's IP and node port or the pod's IP and port. Service implementations may use this information to adjust traffic routing.
Ingress is a list containing ingress points for the load-balancer. Traffic intended for the service should be sent to these ingress points.
PortStatus
PortStatus represents the error condition of a service port
Field
Description
error string
Error is to record the problem with the service port The format of the error shall comply with the following rules: - built-in error values shall be specified in this file and those shall use CamelCase names - cloud provider specific error values must have names that comply with the format foo.example.com/CamelCase.

name string
The name of this port within the service. This must be a DNS_LABEL. All ports within a ServiceSpec must have unique names. When considering the endpoints for a Service, this must match the 'name' field in the EndpointPort. Optional if only one ServicePort is defined on this service.
nodePort integer
The port on each node on which this service is exposed when type is NodePort or LoadBalancer. Usually assigned by the system. If a value is specified, in-range, and not in use it will be used, otherwise the operation will fail. If not specified, a port will be allocated if this Service requires one. If this field is specified when creating a Service which does not need it, creation will fail.

gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential
boolean
if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
dryRun
string
When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
gracePeriodSeconds
integer
The duration in seconds before the object should be deleted. Value must be non-negative integer. The value zero indicates delete immediately. If this value is nil, the default grace period for the specified type will be used. Defaults to a per object value if not specified. zero means delete immediately.
ignoreStoreReadErrorWithClusterBreakingPotential

if set to true, it will trigger an unsafe deletion of the resource in case the normal deletion flow fails with a corrupt object error. A resource is considered corrupt if it can not be retrieved from the underlying storage successfully because of a) its data can not be transformed e.g. decryption failure, or b) it fails to decode into an object. NOTE: unsafe deletion ignores finalizer constraints, skips precondition checks, and removes the object from the storage. WARNING: This may potentially break the cluster if the workload associated with the resource being unsafe-deleted relies on normal deletion flow. Use only if you REALLY know what you are doing. The default value is false, and the user must opt in to enable it
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
orphanDependents
boolean
Deprecated: please use the PropagationPolicy, this field will be deprecated in 1.7. Should the dependent objects be orphaned. If true/false, the "orphan" finalizer will be added to/removed from the object's finalizers list. Either this field or PropagationPolicy may be set, but not both.
propagationPolicy
string
Whether and how garbage collection will be performed. Either this field or OrphanDependents may be set, but not both. The default policy is decided by the existing finalizer set in the metadata.finalizers and the resource-specific default policy. Acceptable values are: 'Orphan' - orphan the dependents; 'Background' - allow the garbage collector to delete the dependents in the background; 'Foreground' - a cascading policy that deletes all dependents in the foreground.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64. Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.

Query Parameters
Name
Type
Description
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
allowWatchBookmarks
boolean
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset

Examples: 2-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x8000000000000000') shard 1: shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') 4-shard split: shard 0: shardRange(object.metadata.uid, '0x0000000000000000', '0x4000000000000000') shard 1: shardRange(object.metadata.uid, '0x4000000000000000', '0x8000000000000000') shard 2: shardRange(object.metadata.uid, '0x8000000000000000', '0xc000000000000000') shard 3: shardRange(object.metadata.uid, '0xc000000000000000', '0x10000000000000000') This is an alpha field and requires enabling the ShardedListAndWatch feature gate.
timeoutSeconds
integer
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
boolean
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored.
continue
string
The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.
fieldSelector
string
A selector to restrict the list of returned objects by their fields. Defaults to everything.
labelSelector
string
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
integer
limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.
pretty
string
If 'true', then the output is pretty printed. Defaults to 'false' unless the user-agent indicates a browser or command-line HTTP tool (curl and wget).
resourceVersion
string
resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
resourceVersionMatch
string
resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset
sendInitialEvents
boolean
`sendInitialEvents=true` may be set together with `watch=true`. In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `"k8s.io/initial-events-end": "true"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of the watch request is as following: - `resourceVersionMatch` = NotOlderThan is interpreted as "data at least as new as the provided `resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion` at least as fresh as the one provided by the ListOptions. If `resourceVersion` is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - `resourceVersionMatch` set to any other value or unset Invalid error is returned. Defaults to true if `resourceVersion=""` or `resourceVersion="0"` (for backward compatibility reasons) and to false otherwise.
shardSelector
string
shardSelector restricts the list of returned objects using a CEL-based shard selector expression. The format uses the shardRange() function combined with || (logical OR) to specify one or more hash ranges: shardRange(object.metadata.uid, '0x0', '0x8000000000000000') shardRange(object.metadata.uid, '0x0', '0x8000000000000000') || shardRange(object.metadata.uid, '0x8000000000000000', '0x10000000000000000') Field paths use CEL-style object-rooted syntax (e.g. "object.metadata.uid"), NOT the fieldSelector format ("metadata.uid"). Currently supported paths: - object.metadata.uid - object.metadata.namespace hexStart and hexEnd are single-quoted CEL string literals with a '0x' prefix, defining the inclusive lower and exclusive upper bounds over the 64-bit FNV-1a hash space. The full range is [0x0, 0x10000000000000000), where the exclusive upper bound equals 2^64.
