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.

Pod is a collection of containers that can run on a host. This resource is created by clients and scheduled onto hosts.
PodSpec
PodSpec is a description of a pod.
Containers
containers ([]Container), required
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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.
initContainers ([]Container)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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 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/
ephemeralContainers ([]EphemeralContainer)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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.

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
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.

PodOS defines the OS parameters of a pod.
Volumes
Scheduling
nodeSelector (map[string]string)
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/
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
affinity (Affinity)
If specified, the pod's scheduling constraints
Affinity is a group of affinity scheduling rules.
affinity.nodeAffinity (NodeAffinity)
Describes node affinity scheduling rules for the pod.

Describes pod affinity scheduling rules (e.g. co-locate this pod in the same node, zone, etc. as some other pod(s)).
affinity.podAntiAffinity (PodAntiAffinity)
Describes pod anti-affinity scheduling rules (e.g. avoid putting this pod in the same node, zone, etc. as some other pod(s)).
tolerations ([]Toleration)
Atomic: will be replaced during a merge
If specified, the pod's tolerations.
The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .
tolerations.key (string)
Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.
tolerations.operator (string)
Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.
tolerations.value (string)
Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.
tolerations.effect (string)
Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
tolerations.tolerationSeconds (int64)
TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.
schedulerName (string)
If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler.
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
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.
priority (int32)
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.
preemptionPolicy (string)
PreemptionPolicy is the Policy for preempting pods with lower priority. One of Never, PreemptLowerPriority. Defaults to PreemptLowerPriority if unset.
topologySpreadConstraints ([]TopologySpreadConstraint)
Patch strategy: merge on key topologyKey
Map: unique values on keys topologyKey, whenUnsatisfiable
will be kept during a merge
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.
TopologySpreadConstraint specifies how to spread matching pods among the given topology.
topologySpreadConstraints.maxSkew (int32), required
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.
topologySpreadConstraints.topologyKey (string), required
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 <key, value> 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.
topologySpreadConstraints.whenUnsatisfiable (string), required
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.
topologySpreadConstraints.labelSelector (LabelSelector)
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.
topologySpreadConstraints.matchLabelKeys ([]string)
Atomic: will be replaced during a merge
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).
topologySpreadConstraints.minDomains (int32)
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.
topologySpreadConstraints.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. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.
topologySpreadConstraints.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. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.
overhead (map[string]Quantity)
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

terminationGracePeriodSeconds (int64)
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.
activeDeadlineSeconds (int64)
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.
readinessGates ([]PodReadinessGate)
Atomic: will be replaced during a merge
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
PodReadinessGate contains the reference to a pod condition

ConditionType refers to a condition in the pod's condition list with matching type.
Hostname and Name resolution
hostname (string)
Specifies the hostname of the Pod If not specified, the pod's hostname will be set to a system-defined value.
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.
subdomain (string)
If specified, the fully qualified Pod hostname will be "<hostname>.<subdomain>.<pod namespace>.svc.<cluster domain>". If not specified, the pod will not have a domainname at all.

Atomic: will be replaced during a merge
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.

Alpha level
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. This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature.
resourceClaims ([]PodResourceClaim)
Patch strategies: retainKeys, merge on key name
Map: unique values on key name will be kept during a merge

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.
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.
schedulingGates ([]PodSchedulingGate)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge

A single application container that you want to run within a pod.
Image
Entrypoint
command ([]string)
Atomic: will be replaced during a merge
Entrypoint array. Not executed within a shell. The container image's ENTRYPOINT is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell
args ([]string)
Atomic: will be replaced during a merge
Arguments to the entrypoint. The container image's CMD is used if this is not provided. Variable references $(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double $$ are reduced to a single $, which allows for escaping the $(VAR_NAME) syntax: i.e. "$$(VAR_NAME)" will produce the string literal "$(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell

Lifecycle
lifecycle (Lifecycle)
Actions that the management system should take in response to container lifecycle events. Cannot be updated.
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.
lifecycle.postStart (LifecycleHandler)
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
lifecycle.preStop (LifecycleHandler)
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. More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks
terminationMessagePath (string)
Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem.

startupProbe (Probe)
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
restartPolicy (string)
RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. 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.
Security Context
securityContext (SecurityContext)
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/

securityContext.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.
securityContext.runAsGroup (int64)

SeccompProfile defines a pod/container's seccomp profile settings. Only one profile source may be set.
securityContext.seccompProfile.type (string), required
type indicates which kind of seccomp profile will be applied. Valid options are:

In addition, if HostProcess is true then HostNetwork must also be set to true.
securityContext.windowsOptions.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.
Debugging
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
tty (boolean)
Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false.
EphemeralContainer
An EphemeralContainer is a temporary container that you may add to an existing Pod for user-initiated activities such as debugging. Ephemeral containers have no resource or scheduling guarantees, and they will not be restarted when they exit or when a Pod is removed or restarted. The kubelet may evict a Pod if an ephemeral container causes the Pod to exceed its resource allocation.
To add an ephemeral container, use the ephemeralcontainers subresource of an existing Pod. Ephemeral containers may not be removed or restarted.

Name of the ephemeral container specified as a DNS_LABEL. This name must be unique among all containers, init containers and ephemeral containers.
targetContainerName (string)
If set, the name of the container from PodSpec that this ephemeral container targets. The ephemeral container will be run in the namespaces (IPC, PID, etc) of this container. If not set then the ephemeral container uses the namespaces configured in the Pod spec.
The container runtime must implement support for this feature. If the runtime does not support namespace targeting then the result of setting this field is undefined.

Name must match the name of one entry in pod.spec.resourceClaims of the Pod where this field is used. It makes that resource available inside a container.
resources.claims.request (string)
Request is the name chosen for a request in the referenced claim. If empty, everything from the claim is made available, otherwise only the result of this request.

lifecycle (Lifecycle)
Lifecycle is not allowed for ephemeral containers.
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.
lifecycle.postStart (LifecycleHandler)
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
lifecycle.preStop (LifecycleHandler)
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. More info: https://kubernetes.io/docs/concepts/containers/container-lifecycle-hooks/#container-hooks

Command is the command line to execute inside the container, the working directory for the command is root ('/') in the container's filesystem. The command is simply exec'd, it is not run inside a shell, so traditional shell instructions ('|', etc) won't work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy.
httpGet (HTTPGetAction)
HTTPGet specifies the http request to perform.
HTTPGetAction describes an action based on HTTP Get requests.
httpGet.port (IntOrString), required
Name or number of the port to access on the container. Number must be in the range 1 to 65535. Name must be an IANA_SVC_NAME.

Host name to connect to, defaults to the pod IP. You probably want to set "Host" in httpHeaders instead.
httpGet.httpHeaders ([]HTTPHeader)
Atomic: will be replaced during a merge
Custom headers to set in the request. HTTP allows repeated headers.
HTTPHeader describes a custom header to be used in HTTP probes

TCPSocketAction describes an action based on opening a socket
tcpSocket.port (IntOrString), required
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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

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.

container (in query): string
The container for which to stream logs. Defaults to only container if there is one container in the pod.
follow (in query): boolean
Follow the log stream of the pod. Defaults to false.
insecureSkipTLSVerifyBackend (in query): 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).

Return previous terminated container logs. Defaults to false.
sinceSeconds (in query): 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.
tailLines (in query): 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
timestamps (in query): boolean
If true, add an RFC3339 or RFC3339Nano timestamp at the beginning of every line of log output. Defaults to false.

1.6 - Deployment
Deployment enables declarative updates for Pods and ReplicaSets.
apiVersion: apps/v1
import "k8s.io/api/apps/v1"
Deployment
Deployment enables declarative updates for Pods and ReplicaSets.
DeploymentSpec
DeploymentSpec is the specification of the desired behavior of the Deployment.
selector (LabelSelector), required
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.
template (PodTemplateSpec), required
Template describes the pods that will be created. The only allowed template.spec.restartPolicy value is "Always".
replicas (int32)
Number of desired pods. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.
minReadySeconds (int32)
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)
strategy (DeploymentStrategy)
Patch strategy: retainKeys
The deployment strategy to use to replace existing pods with new ones.
DeploymentStrategy describes how to replace existing pods with new ones.
strategy.type (string)
Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.
strategy.rollingUpdate (RollingUpdateDeployment)
Rolling update config params. Present only if DeploymentStrategyType = RollingUpdate.
Spec to control the desired behavior of rolling update.
strategy.rollingUpdate.maxSurge (IntOrString)
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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
strategy.rollingUpdate.maxUnavailable (IntOrString)
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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
revisionHistoryLimit (int32)
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.
progressDeadlineSeconds (int32)
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.
paused (boolean)
Indicates that the deployment is paused.
DeploymentStatus
DeploymentStatus is the most recently observed status of the Deployment.
replicas (int32)
Total number of non-terminated pods targeted by this deployment (their labels match the selector).
availableReplicas (int32)
Total number of available pods (ready for at least minReadySeconds) targeted by this deployment.
readyReplicas (int32)
readyReplicas is the number of pods targeted by this Deployment with a Ready Condition.
unavailableReplicas (int32)
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 (int32)
Total number of non-terminated pods targeted by this deployment that have the desired template spec.
collisionCount (int32)
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.

1.7 - StatefulSet
StatefulSet represents a set of pods with consistent identities.
apiVersion: apps/v1
import "k8s.io/api/apps/v1"
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.
StatefulSetSpec
A StatefulSetSpec is the specification of a StatefulSet.
serviceName (string), required
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.
selector (LabelSelector), required
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
template (PodTemplateSpec), required
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 <statefulsetname>-<podindex>. 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".
replicas (int32)
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.
updateStrategy (StatefulSetUpdateStrategy)
updateStrategy indicates the StatefulSetUpdateStrategy that will be employed to update Pods in the StatefulSet when a revision is made to Template.
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.
updateStrategy.type (string)
Type indicates the type of the StatefulSetUpdateStrategy. Default is RollingUpdate.
updateStrategy.rollingUpdate (RollingUpdateStatefulSetStrategy)
RollingUpdate is used to communicate parameters when Type is RollingUpdateStatefulSetStrategyType.
RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType.
updateStrategy.rollingUpdate.maxUnavailable (IntOrString)
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 alpha-level and is only honored by servers that enable the MaxUnavailableStatefulSet feature. 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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
updateStrategy.rollingUpdate.partition (int32)
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.
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.
revisionHistoryLimit (int32)
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.
volumeClaimTemplates ([]PersistentVolumeClaim)
Atomic: will be replaced during a merge
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.
minReadySeconds (int32)
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)
persistentVolumeClaimRetentionPolicy (StatefulSetPersistentVolumeClaimRetentionPolicy)
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. This requires the StatefulSetAutoDeletePVC feature gate to be enabled, which is beta.
StatefulSetPersistentVolumeClaimRetentionPolicy describes the policy used for PVCs created from the StatefulSet VolumeClaimTemplates.
persistentVolumeClaimRetentionPolicy.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.
persistentVolumeClaimRetentionPolicy.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.
ordinals (StatefulSetOrdinals)
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.
StatefulSetOrdinals describes the policy used for replica ordinal assignment in this StatefulSet.
ordinals.start (int32)
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).
StatefulSetStatus
StatefulSetStatus represents the current state of a StatefulSet.
replicas (int32), required
replicas is the number of Pods created by the StatefulSet controller.
readyReplicas (int32)
readyReplicas is the number of pods created for this StatefulSet with a Ready Condition.
currentReplicas (int32)
currentReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by currentRevision.
updatedReplicas (int32)
updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by updateRevision.
availableReplicas (int32)
Total number of available pods (ready for at least minReadySeconds) targeted by this statefulset.
collisionCount (int32)
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.
conditions ([]StatefulSetCondition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
Represents the latest available observations of a statefulset's current state.
StatefulSetCondition describes the state of a statefulset at a certain point.
conditions.status (string), required
Status of the condition, one of True, False, Unknown.
conditions.type (string), required
Type of statefulset condition.
conditions.lastTransitionTime (Time)
Last time the condition transitioned from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
A human readable message indicating details about the transition.
conditions.reason (string)
The reason for the condition's last transition.
currentRevision (string)
currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [0,currentReplicas).
updateRevision (string)
updateRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [replicas-updatedReplicas,replicas)
observedGeneration (int64)
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.
StatefulSetList
StatefulSetList is a collection of StatefulSets.

1.8 - ControllerRevision
ControllerRevision implements an immutable snapshot of state data.
apiVersion: apps/v1
import "k8s.io/api/apps/v1"
ControllerRevision
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.
apiVersion: apps/v1
kind: ControllerRevision
metadata (ObjectMeta)
Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
revision (int64), required
Revision indicates the revision of the state represented by Data.
data (RawExtension)
Data is the serialized representation of the state.
*RawExtension is used to hold extensions in external versions.
To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.
// Internal package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.Object json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// External package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.RawExtension json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// On the wire, the JSON will look something like this:
{
"kind":"MyAPIObject",
"apiVersion":"v1",
"myPlugin": {
"kind":"PluginA",
"aOption":"foo",
},
}
So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*

1.9 - DaemonSet
DaemonSet represents the configuration of a daemon set.
apiVersion: apps/v1
import "k8s.io/api/apps/v1"
DaemonSet
DaemonSet represents the configuration of a daemon set.
DaemonSetSpec
DaemonSetSpec is the specification of a daemon set.
selector (LabelSelector), required
A label query over pods that are managed by the daemon set. Must match in order to be controlled. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors
template (PodTemplateSpec), required
An object that describes the pod that will be created. The DaemonSet will create exactly one copy of this pod on every node that matches the template's node selector (or on every node if no node selector is specified). The only allowed template.spec.restartPolicy value is "Always". More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#pod-template
minReadySeconds (int32)
The minimum number of seconds for which a newly created DaemonSet 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).
updateStrategy (DaemonSetUpdateStrategy)
An update strategy to replace existing DaemonSet pods with new pods.
DaemonSetUpdateStrategy is a struct used to control the update strategy for a DaemonSet.
updateStrategy.type (string)
Type of daemon set update. Can be "RollingUpdate" or "OnDelete". Default is RollingUpdate.
updateStrategy.rollingUpdate (RollingUpdateDaemonSet)
Rolling update config params. Present only if type = "RollingUpdate".
Spec to control the desired behavior of daemon set rolling update.
updateStrategy.rollingUpdate.maxSurge (IntOrString)
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 immediatedly 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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
updateStrategy.rollingUpdate.maxUnavailable (IntOrString)
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.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
revisionHistoryLimit (int32)
The number of old history to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.
DaemonSetStatus
DaemonSetStatus represents the current status of a daemon set.
numberReady (int32), required
numberReady is the number of nodes that should be running the daemon pod and have one or more of the daemon pod running with a Ready Condition.
numberAvailable (int32)
The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and available (ready for at least spec.minReadySeconds)
numberUnavailable (int32)
The number of nodes that should be running the daemon pod and have none of the daemon pod running and available (ready for at least spec.minReadySeconds)
numberMisscheduled (int32), required
The number of nodes that are running the daemon pod, but are not supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
desiredNumberScheduled (int32), required
The total number of nodes that should be running the daemon pod (including nodes correctly running the daemon pod). More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
currentNumberScheduled (int32), required
The number of nodes that are running at least 1 daemon pod and are supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
updatedNumberScheduled (int32)
The total number of nodes that are running updated daemon pod
collisionCount (int32)
Count of hash collisions for the DaemonSet. The DaemonSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.
conditions ([]DaemonSetCondition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
Represents the latest available observations of a DaemonSet's current state.
DaemonSetCondition describes the state of a DaemonSet at a certain point.
conditions.status (string), required
Status of the condition, one of True, False, Unknown.
conditions.type (string), required
Type of DaemonSet condition.
conditions.lastTransitionTime (Time)
Last time the condition transitioned from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
A human readable message indicating details about the transition.
conditions.reason (string)
The reason for the condition's last transition.
observedGeneration (int64)
The most recent generation observed by the daemon set controller.

1.10 - Job
Job represents the configuration of a single job.
apiVersion: batch/v1
import "k8s.io/api/batch/v1"
Job
Job represents the configuration of a single job.
JobSpec
JobSpec describes how the job execution will look like.
Replicas
Lifecycle
completions (int32)
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/
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.
backoffLimit (int32)
Specifies the number of retries before marking this job failed. Defaults to 6
activeDeadlineSeconds (int64)
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.
ttlSecondsAfterFinished (int32)
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.
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.
Selector
Beta level
podFailurePolicy (PodFailurePolicy)
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.
PodFailurePolicy describes how failed pods influence the backoffLimit.
podFailurePolicy.rules ([]PodFailurePolicyRule), required
Atomic: will be replaced during a merge
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.
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.
podFailurePolicy.rules.action (string), required
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.
This value is beta-level. It can be used when the
JobBackoffLimitPerIndex
feature gate is enabled (enabled by default). - 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.
podFailurePolicy.rules.onExitCodes (PodFailurePolicyOnExitCodesRequirement)
Represents the requirement on the container exit codes.
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.
podFailurePolicy.rules.onExitCodes.operator (string), required
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.
podFailurePolicy.rules.onExitCodes.values ([]int32), required
Set: unique values will be kept during a merge
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.
podFailurePolicy.rules.onExitCodes.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.
podFailurePolicy.rules.onPodConditions ([]PodFailurePolicyOnPodConditionsPattern)
Atomic: will be replaced during a merge
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.
PodFailurePolicyOnPodConditionsPattern describes a pattern for matching an actual pod condition type.
podFailurePolicy.rules.onPodConditions.status (string), required
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.
podFailurePolicy.rules.onPodConditions.type (string), required
Specifies the required Pod condition type. To match a pod condition it is required that specified type equals the pod condition type.
successPolicy (SuccessPolicy)
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.
This field is beta-level. To use this field, you must enable the JobSuccessPolicy
feature gate (enabled by default).
SuccessPolicy describes when a Job can be declared as succeeded based on the success of some indexes.
successPolicy.rules ([]SuccessPolicyRule), required
Atomic: will be replaced during a merge
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 "SucceededCriteriaMet" 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 describes rule for declaring a Job as succeeded. Each rule must have at least one of the "succeededIndexes" or "succeededCount" specified.
successPolicy.rules.succeededCount (int32)
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.
successPolicy.rules.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.
Alpha level
backoffLimitPerIndex (int32)
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. This field is beta-level. It can be used when the JobBackoffLimitPerIndex
feature gate is enabled (enabled by default).
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.
This field is alpha-level. The job controller accepts setting the field when the feature gate JobManagedBy is enabled (disabled by default).
maxFailedIndexes (int32)
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. This field is beta-level. It can be used when the JobBackoffLimitPerIndex
feature gate is enabled (enabled by default).
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. This is an beta field. To use this, enable the JobPodReplacementPolicy feature toggle. This is on by default.
JobStatus
JobStatus represents the current state of a Job.
startTime (Time)
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.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
completionTime (Time)
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.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
active (int32)
The number of pending and running pods which are not terminating (without a deletionTimestamp). The value is zero for finished jobs.
failed (int32)
The number of pods which reached phase Failed. The value increases monotonically.
succeeded (int32)
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.
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".
conditions ([]JobCondition)
Patch strategy: merge on key type
Atomic: will be replaced during a merge
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/
JobCondition describes current state of a job.
conditions.status (string), required
Status of the condition, one of True, False, Unknown.
conditions.type (string), required
Type of job condition, Complete or Failed.
conditions.lastProbeTime (Time)
Last time the condition was checked.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.lastTransitionTime (Time)
Last time the condition transit from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
Human readable message indicating details about last transition.
conditions.reason (string)
(brief) reason for the condition's last transition.
uncountedTerminatedPods (UncountedTerminatedPods)
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:
- 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.
UncountedTerminatedPods holds UIDs of Pods that have terminated but haven't been accounted in Job status counters.
uncountedTerminatedPods.failed ([]string)
Set: unique values will be kept during a merge
failed holds UIDs of failed Pods.
uncountedTerminatedPods.succeeded ([]string)
Set: unique values will be kept during a merge
succeeded holds UIDs of succeeded Pods.
Beta level
Alpha level
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.
This field is beta-level. It can be used when the JobBackoffLimitPerIndex
feature gate is enabled (enabled by default).
terminating (int32)
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).

CronJob
CronJob represents the configuration of a single cron job.
CronJobSpec
CronJobSpec describes how the job execution will look like and when it will actually run.
jobTemplate (JobTemplateSpec), required
Specifies the job that will be created when executing a CronJob.
JobTemplateSpec describes the data a Job should have when created from a template

The schedule in Cron format, see https://en.wikipedia.org/wiki/Cron.
timeZone (string)
The time zone name for the given schedule, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones. If not specified, this will default to the time zone of the kube-controller-manager process. The set of valid time zone names and the time zone offset is loaded from the system-wide time zone database by the API server during CronJob validation and the controller manager during execution. If no system-wide time zone database can be found a bundled version of the database is used instead. If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host configuration, the controller will stop creating new new Jobs and will create a system event with the reason UnknownTimeZone. More information can be found in https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#time-zones
concurrencyPolicy (string)

startingDeadlineSeconds (int64)
Optional deadline in seconds for starting the job if it misses scheduled time for any reason. Missed jobs executions will be counted as failed ones.
suspend (boolean)
This flag tells the controller to suspend subsequent executions, it does not apply to already started executions. Defaults to false.
successfulJobsHistoryLimit (int32)
The number of successful finished jobs to retain. Value must be non-negative integer. Defaults to 3.

CrossVersionObjectReference contains enough information to let you identify the referred resource.
minReplicas (int32)
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.
behavior (HorizontalPodAutoscalerBehavior)
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.
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).
HPAScalingRules configures the scaling behavior for one direction. These 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.

behavior.scaleDown.stabilizationWindowSeconds (int32)
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).
behavior.scaleUp (HPAScalingRules)

metrics ([]MetricSpec)
Atomic: will be replaced during a merge
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.

1.16 - ResourceClaim v1alpha3
ResourceClaim describes a request for access to resources in the cluster, for use by workloads.
apiVersion: resource.k8s.io/v1alpha3
import "k8s.io/api/resource/v1alpha3"
ResourceClaim
ResourceClaim describes a request for access to resources in the cluster, for use by workloads. For example, if a workload needs an accelerator device with specific properties, this is how that request is expressed. The status stanza tracks whether this claim has been satisfied and what specific resources have been allocated.
This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.
apiVersion: resource.k8s.io/v1alpha3
kind: ResourceClaim
metadata (ObjectMeta)
Standard object metadata
spec (ResourceClaimSpec), required
Spec describes what is being requested and how to configure it. The spec is immutable.
status (ResourceClaimStatus)
Status describes whether the claim is ready to use and what has been allocated.
ResourceClaimSpec
ResourceClaimSpec defines what is being requested in a ResourceClaim and how to configure it.
controller (string)
Controller is the name of the DRA driver that is meant to handle allocation of this claim. If empty, allocation is handled by the scheduler while scheduling a pod.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
devices (DeviceClaim)
Devices defines how to request devices.
DeviceClaim defines how to request devices with a ResourceClaim.
devices.config ([]DeviceClaimConfiguration)
Atomic: will be replaced during a merge
This field holds configuration for multiple potential drivers which could satisfy requests in this claim. It is ignored while allocating the claim.
DeviceClaimConfiguration is used for configuration parameters in DeviceClaim.
devices.config.opaque (OpaqueDeviceConfiguration)
Opaque provides driver-specific configuration parameters.
OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.
devices.config.opaque.driver (string), required
Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.
An admission policy provided by the driver developer could use this to decide whether it needs to validate them.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
devices.config.opaque.parameters (RawExtension), required
Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions.
*RawExtension is used to hold extensions in external versions.
To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.
// Internal package:
type MyAPIObject struct {
runtime.TypeMeta `json:",inline"`
MyPlugin runtime.Object `json:"myPlugin"`
}
type PluginA struct {
AOption string `json:"aOption"`
}
// External package:
type MyAPIObject struct {
runtime.TypeMeta `json:",inline"`
MyPlugin runtime.RawExtension `json:"myPlugin"`
}
type PluginA struct {
AOption string `json:"aOption"`
}
// On the wire, the JSON will look something like this:
{
"kind":"MyAPIObject",
"apiVersion":"v1",
"myPlugin": {
"kind":"PluginA",
"aOption":"foo",
},
}
So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*
devices.config.requests ([]string)
Atomic: will be replaced during a merge
Requests lists the names of requests where the configuration applies. If empty, it applies to all requests.
devices.constraints ([]DeviceConstraint)
Atomic: will be replaced during a merge
These constraints must be satisfied by the set of devices that get allocated for the claim.
DeviceConstraint must have exactly one field set besides Requests.
devices.constraints.matchAttribute (string)
MatchAttribute requires that all devices in question have this attribute and that its type and value are the same across those devices.
For example, if you specified "dra.example.com/numa" (a hypothetical example!), then only devices in the same NUMA node will be chosen. A device which does not have that attribute will not be chosen. All devices should use a value of the same type for this attribute because that is part of its specification, but if one device doesn't, then it also will not be chosen.
Must include the domain qualifier.
devices.constraints.requests ([]string)
Atomic: will be replaced during a merge
Requests is a list of the one or more requests in this claim which must co-satisfy this constraint. If a request is fulfilled by multiple devices, then all of the devices must satisfy the constraint. If this is not specified, this constraint applies to all requests in this claim.
devices.requests ([]DeviceRequest)
Atomic: will be replaced during a merge
Requests represent individual requests for distinct devices which must all be satisfied. If empty, nothing needs to be allocated.
*DeviceRequest is a request for devices required for a claim. This is typically a request for a single resource like a device, but can also ask for several identical devices.
A DeviceClassName is currently required. Clients must check that it is indeed set. It's absence indicates that something changed in a way that is not supported by the client yet, in which case it must refuse to handle the request.*
devices.requests.deviceClassName (string), required
DeviceClassName references a specific DeviceClass, which can define additional configuration and selectors to be inherited by this request.
A class is required. Which classes are available depends on the cluster.
Administrators may use this to restrict which devices may get requested by only installing classes with selectors for permitted devices. If users are free to request anything without restrictions, then administrators can create an empty DeviceClass for users to reference.
devices.requests.name (string), required
Name can be used to reference this request in a pod.spec.containers[].resources.claims entry and in a constraint of the claim.
Must be a DNS label.
devices.requests.adminAccess (boolean)
AdminAccess indicates that this is a claim for administrative access to the device(s). Claims with AdminAccess are expected to be used for monitoring or other management services for a device. They ignore all ordinary claims to the device with respect to access modes and any resource allocations.
devices.requests.allocationMode (string)
AllocationMode and its related fields define how devices are allocated to satisfy this request. Supported values are:
ExactCount: This request is for a specific number of devices.
This is the default. The exact number is provided in the
count field.
All: This request is for all of the matching devices in a pool.
Allocation will fail if some devices are already allocated,
unless adminAccess is requested.
If AlloctionMode is not specified, the default mode is ExactCount. If the mode is ExactCount and count is not specified, the default count is one. Any other requests must specify this field.
More modes may get added in the future. Clients must refuse to handle requests with unknown modes.
devices.requests.count (int64)
Count is used only when the count mode is "ExactCount". Must be greater than zero. If AllocationMode is ExactCount and this field is not specified, the default is one.
devices.requests.selectors ([]DeviceSelector)
Atomic: will be replaced during a merge
Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this request. All selectors must be satisfied for a device to be considered.
DeviceSelector must have exactly one field set.
devices.requests.selectors.cel (CELDeviceSelector)
CEL contains a CEL expression for selecting a device.
CELDeviceSelector contains a CEL expression for selecting a device.
devices.requests.selectors.cel.expression (string), required
Expression is a CEL expression which evaluates a single device. It must evaluate to true when the device under consideration satisfies the desired criteria, and false when it does not. Any other result is an error and causes allocation of devices to abort.
The expression's input is an object named "device", which carries the following properties:
- driver (string): the name of the driver which defines this device.
- attributes (map[string]object): the device's attributes, grouped by prefix
(e.g. device.attributes["dra.example.com"] evaluates to an object with all
of the attributes which were prefixed by "dra.example.com".
- capacity (map[string]object): the device's capacities, grouped by prefix.
Example: Consider a device with driver="dra.example.com", which exposes two attributes named "model" and "ext.example.com/family" and which exposes one capacity named "modules". This input to this expression would have the following fields:
device.driver
device.attributes["dra.example.com"].model
device.attributes["ext.example.com"].family
device.capacity["dra.example.com"].modules
The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.
The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity.
If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort.
A robust expression should check for the existence of attributes before referencing them.
For ease of use, the cel.bind() function is enabled, and can be used to simplify expressions that access multiple attributes with the same domain. For example:
cel.bind(dra, device.attributes["dra.example.com"], dra.someBool && dra.anotherBool)
ResourceClaimStatus
ResourceClaimStatus tracks whether the resource has been allocated and what the result of that was.
allocation (AllocationResult)
Allocation is set once the claim has been allocated successfully.
AllocationResult contains attributes of an allocated resource.
allocation.controller (string)
Controller is the name of the DRA driver which handled the allocation. That driver is also responsible for deallocating the claim. It is empty when the claim can be deallocated without involving a driver.
A driver may allocate devices provided by other drivers, so this driver name here can be different from the driver names listed for the results.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
allocation.devices (DeviceAllocationResult)
Devices is the result of allocating devices.
DeviceAllocationResult is the result of allocating devices.
allocation.devices.config ([]DeviceAllocationConfiguration)
Atomic: will be replaced during a merge
This field is a combination of all the claim and class configuration parameters. Drivers can distinguish between those based on a flag.
This includes configuration parameters for drivers which have no allocated devices in the result because it is up to the drivers which configuration parameters they support. They can silently ignore unknown configuration parameters.
DeviceAllocationConfiguration gets embedded in an AllocationResult.
allocation.devices.config.source (string), required
Source records whether the configuration comes from a class and thus is not something that a normal user would have been able to set or from a claim.
allocation.devices.config.opaque (OpaqueDeviceConfiguration)
Opaque provides driver-specific configuration parameters.
OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.
allocation.devices.config.opaque.driver (string), required
Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.
An admission policy provided by the driver developer could use this to decide whether it needs to validate them.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
allocation.devices.config.opaque.parameters (RawExtension), required
Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions.
*RawExtension is used to hold extensions in external versions.
To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.
// Internal package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.Object json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// External package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.RawExtension json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// On the wire, the JSON will look something like this:
{
"kind":"MyAPIObject",
"apiVersion":"v1",
"myPlugin": {
"kind":"PluginA",
"aOption":"foo",
},
}
So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*
allocation.devices.config.requests ([]string)
Atomic: will be replaced during a merge
Requests lists the names of requests where the configuration applies. If empty, its applies to all requests.
allocation.devices.results ([]DeviceRequestAllocationResult)
Atomic: will be replaced during a merge
Results lists all allocated devices.
DeviceRequestAllocationResult contains the allocation result for one request.
allocation.devices.results.device (string), required
Device references one device instance via its name in the driver's resource pool. It must be a DNS label.
allocation.devices.results.driver (string), required
Driver specifies the name of the DRA driver whose kubelet plugin should be invoked to process the allocation once the claim is needed on a node.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
allocation.devices.results.pool (string), required
This name together with the driver name and the device name field identify which device was allocated (\<driver name>/\<pool name>/\<device name>
).
Must not be longer than 253 characters and may contain one or more DNS sub-domains separated by slashes.
allocation.devices.results.request (string), required
Request is the name of the request in the claim which caused this device to be allocated. Multiple devices may have been allocated per request.
allocation.nodeSelector (NodeSelector)
NodeSelector defines where the allocated resources are available. If unset, they are available everywhere.
A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.
allocation.nodeSelector.nodeSelectorTerms ([]NodeSelectorTerm), required
Atomic: will be replaced during a merge
Required. A list of node selector terms. The terms are ORed.
A null or empty node selector term matches no objects. The requirements of them are ANDed. The TopologySelectorTerm type implements a subset of the NodeSelectorTerm.
allocation.nodeSelector.nodeSelectorTerms.matchExpressions ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's labels.
allocation.nodeSelector.nodeSelectorTerms.matchFields ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's fields.
deallocationRequested (boolean)
Indicates that a claim is to be deallocated. While this is set, no new consumers may be added to ReservedFor.
This is only used if the claim needs to be deallocated by a DRA driver. That driver then must deallocate this claim and reset the field together with clearing the Allocation field.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
reservedFor ([]ResourceClaimConsumerReference)
Patch strategy: merge on key uid
Map: unique values on key uid will be kept during a merge
ReservedFor indicates which entities are currently allowed to use the claim. A Pod which references a ResourceClaim which is not reserved for that Pod will not be started. A claim that is in use or might be in use because it has been reserved must not get deallocated.
In a cluster with multiple scheduler instances, two pods might get scheduled concurrently by different schedulers. When they reference the same ResourceClaim which already has reached its maximum number of consumers, only one pod can be scheduled.
Both schedulers try to add their pod to the claim.status.reservedFor field, but only the update that reaches the API server first gets stored. The other one fails with an error and the scheduler which issued it knows that it must put the pod back into the queue, waiting for the ResourceClaim to become usable again.
There can be at most 32 such reservations. This may get increased in the future, but not reduced.
ResourceClaimConsumerReference contains enough information to let you locate the consumer of a ResourceClaim. The user must be a resource in the same namespace as the ResourceClaim.
reservedFor.name (string), required
Name is the name of resource being referenced.
reservedFor.resource (string), required
Resource is the type of resource being referenced, for example "pods".
reservedFor.uid (string), required
UID identifies exactly one incarnation of the resource.

1.17 - ResourceClaim v1beta1
ResourceClaim describes a request for access to resources in the cluster, for use by workloads.
apiVersion: resource.k8s.io/v1beta1
import "k8s.io/api/resource/v1beta1"
ResourceClaim
ResourceClaim describes a request for access to resources in the cluster, for use by workloads. For example, if a workload needs an accelerator device with specific properties, this is how that request is expressed. The status stanza tracks whether this claim has been satisfied and what specific resources have been allocated.
This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.
apiVersion: resource.k8s.io/v1beta1
kind: ResourceClaim
metadata (ObjectMeta)
Standard object metadata
spec (ResourceClaimSpec), required
Spec describes what is being requested and how to configure it. The spec is immutable.
status (ResourceClaimStatus)
Status describes whether the claim is ready to use and what has been allocated.
ResourceClaimSpec
ResourceClaimSpec defines what is being requested in a ResourceClaim and how to configure it.
controller (string)
Controller is the name of the DRA driver that is meant to handle allocation of this claim. If empty, allocation is handled by the scheduler while scheduling a pod.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
devices (DeviceClaim)
Devices defines how to request devices.
DeviceClaim defines how to request devices with a ResourceClaim.
devices.config ([]DeviceClaimConfiguration)
Atomic: will be replaced during a merge
This field holds configuration for multiple potential drivers which could satisfy requests in this claim. It is ignored while allocating the claim.
DeviceClaimConfiguration is used for configuration parameters in DeviceClaim.
devices.config.opaque (OpaqueDeviceConfiguration)
Opaque provides driver-specific configuration parameters.
OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.
devices.config.opaque.driver (string), required
Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.
An admission policy provided by the driver developer could use this to decide whether it needs to validate them.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

devices.config.requests ([]string)
Atomic: will be replaced during a merge
Requests lists the names of requests where the configuration applies. If empty, it applies to all requests.
devices.constraints ([]DeviceConstraint)
Atomic: will be replaced during a merge
These constraints must be satisfied by the set of devices that get allocated for the claim.
DeviceConstraint must have exactly one field set besides Requests.
devices.constraints.matchAttribute (string)
MatchAttribute requires that all devices in question have this attribute and that its type and value are the same across those devices.
For example, if you specified "dra.example.com/numa" (a hypothetical example!), then only devices in the same NUMA node will be chosen. A device which does not have that attribute will not be chosen. All devices should use a value of the same type for this attribute because that is part of its specification, but if one device doesn't, then it also will not be chosen.
Must include the domain qualifier.
devices.constraints.requests ([]string)
Atomic: will be replaced during a merge
Requests is a list of the one or more requests in this claim which must co-satisfy this constraint. If a request is fulfilled by multiple devices, then all of the devices must satisfy the constraint. If this is not specified, this constraint applies to all requests in this claim.
devices.requests ([]DeviceRequest)
Atomic: will be replaced during a merge
Requests represent individual requests for distinct devices which must all be satisfied. If empty, nothing needs to be allocated.
*DeviceRequest is a request for devices required for a claim. This is typically a request for a single resource like a device, but can also ask for several identical devices.
A DeviceClassName is currently required. Clients must check that it is indeed set. It's absence indicates that something changed in a way that is not supported by the client yet, in which case it must refuse to handle the request.*
devices.requests.deviceClassName (string), required
DeviceClassName references a specific DeviceClass, which can define additional configuration and selectors to be inherited by this request.
A class is required. Which classes are available depends on the cluster.
Administrators may use this to restrict which devices may get requested by only installing classes with selectors for permitted devices. If users are free to request anything without restrictions, then administrators can create an empty DeviceClass for users to reference.
devices.requests.name (string), required
Name can be used to reference this request in a pod.spec.containers[].resources.claims entry and in a constraint of the claim.
Must be a DNS label.
devices.requests.adminAccess (boolean)
AdminAccess indicates that this is a claim for administrative access to the device(s). Claims with AdminAccess are expected to be used for monitoring or other management services for a device. They ignore all ordinary claims to the device with respect to access modes and any resource allocations.
devices.requests.allocationMode (string)
AllocationMode and its related fields define how devices are allocated to satisfy this request. Supported values are:
ExactCount: This request is for a specific number of devices.
This is the default. The exact number is provided in the
count field.
All: This request is for all of the matching devices in a pool.
Allocation will fail if some devices are already allocated,
unless adminAccess is requested.
If AlloctionMode is not specified, the default mode is ExactCount. If the mode is ExactCount and count is not specified, the default count is one. Any other requests must specify this field.
More modes may get added in the future. Clients must refuse to handle requests with unknown modes.
devices.requests.count (int64)
Count is used only when the count mode is "ExactCount". Must be greater than zero. If AllocationMode is ExactCount and this field is not specified, the default is one.
devices.requests.selectors ([]DeviceSelector)
Atomic: will be replaced during a merge
Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this request. All selectors must be satisfied for a device to be considered.

device.capacity["dra.example.com"].modules
The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.

1.20 - ResourceSlice v1alpha3
ResourceSlice represents one or more resources in a pool of similar resources, managed by a common driver.
apiVersion: resource.k8s.io/v1alpha3
import "k8s.io/api/resource/v1alpha3"
ResourceSlice
ResourceSlice represents one or more resources in a pool of similar resources, managed by a common driver. A pool may span more than one ResourceSlice, and exactly how many ResourceSlices comprise a pool is determined by the driver.
At the moment, the only supported resources are devices with attributes and capacities. Each device in a given pool, regardless of how many ResourceSlices, must have a unique name. The ResourceSlice in which a device gets published may change over time. The unique identifier for a device is the tuple <driver name>, <pool name>, <device name>.
Whenever a driver needs to update a pool, it increments the pool.Spec.Pool.Generation number and updates all ResourceSlices with that new number and new resource definitions. A consumer must only use ResourceSlices with the highest generation number and ignore all others.
When allocating all resources in a pool matching certain criteria or when looking for the best solution among several different alternatives, a consumer should check the number of ResourceSlices in a pool (included in each ResourceSlice) to determine whether its view of a pool is complete and if not, should wait until the driver has completed updating the pool.
For resources that are not local to a node, the node name is not set. Instead, the driver may use a node selector to specify where the devices are available.
This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.
apiVersion: resource.k8s.io/v1alpha3
kind: ResourceSlice
metadata (ObjectMeta)
Standard object metadata
spec (ResourceSliceSpec), required
Contains the information published by the driver.
Changing the spec automatically increments the metadata.generation number.
ResourceSliceSpec
ResourceSliceSpec contains the information published by the driver in one ResourceSlice.
driver (string), required
Driver identifies the DRA driver providing the capacity information. A field selector can be used to list only ResourceSlice objects with a certain driver name.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver. This field is immutable.
pool (ResourcePool), required
Pool describes the pool that this ResourceSlice belongs to.
ResourcePool describes the pool that ResourceSlices belong to.
pool.generation (int64), required
Generation tracks the change in a pool over time. Whenever a driver changes something about one or more of the resources in a pool, it must change the generation in all ResourceSlices which are part of that pool. Consumers of ResourceSlices should only consider resources from the pool with the highest generation number. The generation may be reset by drivers, which should be fine for consumers, assuming that all ResourceSlices in a pool are updated to match or deleted.
Combined with ResourceSliceCount, this mechanism enables consumers to detect pools which are comprised of multiple ResourceSlices and are in an incomplete state.
pool.name (string), required
Name is used to identify the pool. For node-local devices, this is often the node name, but this is not required.
It must not be longer than 253 characters and must consist of one or more DNS sub-domains separated by slashes. This field is immutable.
pool.resourceSliceCount (int64), required
ResourceSliceCount is the total number of ResourceSlices in the pool at this generation number. Must be greater than zero.
Consumers can use this to check whether they have seen all ResourceSlices belonging to the same pool.
allNodes (boolean)
AllNodes indicates that all nodes have access to the resources in the pool.
Exactly one of NodeName, NodeSelector and AllNodes must be set.
devices ([]Device)
Atomic: will be replaced during a merge
Devices lists some or all of the devices in this pool.
Must not have more than 128 entries.
Device represents one individual hardware instance that can be selected based on its attributes. Besides the name, exactly one field must be set.
devices.name (string), required
Name is unique identifier among all devices managed by the driver in the pool. It must be a DNS label.
devices.basic (BasicDevice)
Basic defines one device instance.
BasicDevice defines one device instance.
devices.basic.attributes (map[string]DeviceAttribute)
Attributes defines the set of attributes for this device. The name of each attribute must be unique in that set.
The maximum number of attributes and capacities combined is 32.
DeviceAttribute must have exactly one field set.
devices.basic.attributes.bool (boolean)
BoolValue is a true/false value.
devices.basic.attributes.int (int64)
IntValue is a number.
devices.basic.attributes.string (string)
StringValue is a string. Must not be longer than 64 characters.
devices.basic.attributes.version (string)
VersionValue is a semantic version according to semver.org spec 2.0.0. Must not be longer than 64 characters.
devices.basic.capacity (map[string]Quantity)
Capacity defines the set of capacities for this device. The name of each capacity must be unique in that set.
The maximum number of attributes and capacities combined is 32.
nodeName (string)
NodeName identifies the node which provides the resources in this pool. A field selector can be used to list only ResourceSlice objects belonging to a certain node.
This field can be used to limit access from nodes to ResourceSlices with the same node name. It also indicates to autoscalers that adding new nodes of the same type as some old node might also make new resources available.
Exactly one of NodeName, NodeSelector and AllNodes must be set. This field is immutable.
nodeSelector (NodeSelector)
NodeSelector defines which nodes have access to the resources in the pool, when that pool is not limited to a single node.
Must use exactly one term.
Exactly one of NodeName, NodeSelector and AllNodes must be set.
A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.
nodeSelector.nodeSelectorTerms ([]NodeSelectorTerm), required
Atomic: will be replaced during a merge
Required. A list of node selector terms. The terms are ORed.
A null or empty node selector term matches no objects. The requirements of them are ANDed. The TopologySelectorTerm type implements a subset of the NodeSelectorTerm.
nodeSelector.nodeSelectorTerms.matchExpressions ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's labels.
nodeSelector.nodeSelectorTerms.matchFields ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's fields.

Number or name of the port to access on the pods targeted by the service. Number must be in the range 1 to 65535. Name must be an IANA_SVC_NAME. If this is a string, it will be looked up as a named port in the target Pod's container ports. If this is not specified, the value of the 'port' field is used (an identity map). This field is ignored for services with clusterIP=None, and should be omitted or set equal to the 'port' field. More info: https://kubernetes.io/docs/concepts/services-networking/service/#defining-a-service
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
ports.protocol (string)
The IP protocol for this port. Supports "TCP", "UDP", and "SCTP". Default is TCP.
ports.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.
ports.nodePort (int32)
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. This field will be wiped when updating a Service to no longer need it (e.g. changing type from NodePort to ClusterIP). More info: https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport
ports.appProtocol (string)
The application protocol for this port. This is used as a hint for implementations to offer richer behavior for protocols that they understand. This field follows standard Kubernetes label syntax. Valid values are either:
Un-prefixed protocol names - reserved for IANA standard service names (as per RFC-6335 and https://www.iana.org/assignments/service-names).
Kubernetes-defined prefixed names:
Other protocols should use implementation-defined prefixed names such as mycompany.com/my-custom-protocol.
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
ipFamilies ([]string)
Atomic: will be replaced during a merge
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.
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)
Atomic: will be replaced during a merge
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)
Atomic: will be replaced during a merge
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.
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
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)
Atomic: will be replaced during a merge
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/
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.
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.
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).
healthCheckNodePort (int32)
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.
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.
sessionAffinityConfig (SessionAffinityConfig)
sessionAffinityConfig contains the configurations of session affinity.
SessionAffinityConfig represents the configurations of session affinity.
sessionAffinityConfig.clientIP (ClientIPConfig)
clientIP contains the configurations of Client IP based session affinity.
ClientIPConfig represents the configurations of Client IP based session affinity.
sessionAffinityConfig.clientIP.timeoutSeconds (int32)
timeoutSeconds specifies the seconds of ClientIP type session sticky time. The value must be >0 && <=86400(for 1 day) if ServiceAffinity == "ClientIP". Default value is 10800(for 3 hours).
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.
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 topologically close (e.g., same zone). This is an beta field and requires enabling ServiceTrafficDistribution feature.
ServiceStatus
ServiceStatus represents the current status of a service.
conditions ([]Condition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
Current service state
Condition contains details for one aspect of the current state of this API Resource.
conditions.lastTransitionTime (Time), required
lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string), required
message is a human readable message indicating details about the transition. This may be an empty string.
conditions.reason (string), required
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.
conditions.status (string), required
status of the condition, one of True, False, Unknown.
conditions.type (string), required
type of condition in CamelCase or in foo.example.com/CamelCase.
conditions.observedGeneration (int64)
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.
loadBalancer (LoadBalancerStatus)
LoadBalancer contains the current status of the load-balancer, if one is present.
LoadBalancerStatus represents the status of a load-balancer.
loadBalancer.ingress ([]LoadBalancerIngress)
Atomic: will be replaced during a merge
Ingress is a list containing ingress points for the load-balancer. Traffic intended for the service should be sent to these ingress points.
LoadBalancerIngress represents the status of a load-balancer ingress point: traffic intended for the service should be sent to an ingress point.
loadBalancer.ingress.hostname (string)
Hostname is set for load-balancer ingress points that are DNS based (typically AWS load-balancers)
loadBalancer.ingress.ip (string)
IP is set for load-balancer ingress points that are IP based (typically GCE or OpenStack load-balancers)
loadBalancer.ingress.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.
loadBalancer.ingress.ports ([]PortStatus)
Atomic: will be replaced during a merge
Ports is a list of records of service ports If used, every port defined in the service should have an entry in it
**
loadBalancer.ingress.ports.port (int32), required
Port is the port number of the service port of which status is recorded here
loadBalancer.ingress.ports.protocol (string), required
Protocol is the protocol of the service port of which status is recorded here The supported values are: "TCP", "UDP", "SCTP"
loadBalancer.ingress.ports.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.

Endpoints
Endpoints is a collection of endpoints that implement the actual service. Example:
Name: "mysvc",
Subsets: [

metadata (ObjectMeta)
Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
subsets ([]EndpointSubset)
Atomic: will be replaced during a merge
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.
*EndpointSubset is a group of addresses with a common set of ports. The expanded set of endpoints is the Cartesian product of Addresses x Ports. For example, given:
{
Addresses: [{"ip": "10.10.1.1"}, {"ip": "10.10.2.2"}],
Ports: [{"name": "a", "port": 8675}, {"name": "b", "port": 309}]
}
The resulting set of endpoints can be viewed as:
a: [ 10.10.1.1:8675, 10.10.2.2:8675 ],
b: [ 10.10.1.1:309, 10.10.2.2:309 ]*

EndpointSlice
EndpointSlice represents a subset of the endpoints that implement a service. For a given service there may be multiple EndpointSlice objects, selected by labels, which must be joined to produce the full set of endpoints.
apiVersion: discovery.k8s.io/v1
kind: EndpointSlice
metadata (ObjectMeta)
Standard object's metadata.
addressType (string), required
addressType specifies the type of address carried by this EndpointSlice. All addresses in this slice must be the same type. This field is immutable after creation. The following address types are currently supported: * IPv4: Represents an IPv4 Address. * IPv6: Represents an IPv6 Address. * FQDN: Represents a Fully Qualified Domain Name.
endpoints ([]Endpoint), required
Atomic: will be replaced during a merge
endpoints is a list of unique endpoints in this slice. Each slice may include a maximum of 1000 endpoints.
Endpoint represents a single logical "backend" implementing a service.
endpoints.addresses ([]string), required
Set: unique values will be kept during a merge
addresses of this endpoint. The contents of this field are interpreted according to the corresponding EndpointSlice addressType field. Consumers must handle different types of addresses in the context of their own capabilities. This must contain at least one address but no more than 100. These are all assumed to be fungible and clients may choose to only use the first element. Refer to: https://issue.k8s.io/106267
endpoints.conditions (EndpointConditions)
conditions contains information about the current status of the endpoint.
EndpointConditions represents the current condition of an endpoint.
endpoints.conditions.ready (boolean)
ready indicates that this endpoint is prepared to receive traffic, according to whatever system is managing the endpoint. A nil value indicates an unknown state. In most cases consumers should interpret this unknown state as ready. For compatibility reasons, ready should never be "true" for terminating endpoints, except when the normal readiness behavior is being explicitly overridden, for example when the associated Service has set the publishNotReadyAddresses flag.
endpoints.conditions.serving (boolean)
serving is identical to ready except that it is set regardless of the terminating state of endpoints. This condition should be set to true for a ready endpoint that is terminating. If nil, consumers should defer to the ready condition.
endpoints.conditions.terminating (boolean)
terminating indicates that this endpoint is terminating. A nil value indicates an unknown state. Consumers should interpret this unknown state to mean that the endpoint is not terminating.
endpoints.deprecatedTopology (map[string]string)
deprecatedTopology contains topology information part of the v1beta1 API. This field is deprecated, and will be removed when the v1beta1 API is removed (no sooner than kubernetes v1.24). While this field can hold values, it is not writable through the v1 API, and any attempts to write to it will be silently ignored. Topology information can be found in the zone and nodeName fields instead.
endpoints.hints (EndpointHints)
hints contains information associated with how an endpoint should be consumed.
EndpointHints provides hints describing how an endpoint should be consumed.
endpoints.hints.forZones ([]ForZone)
Atomic: will be replaced during a merge
forZones indicates the zone(s) this endpoint should be consumed by to enable topology aware routing.
ForZone provides information about which zones should consume this endpoint.
endpoints.hostname (string)
hostname of this endpoint. This field may be used by consumers of endpoints to distinguish endpoints from each other (e.g. in DNS names). Multiple endpoints which use the same hostname should be considered fungible (e.g. multiple A values in DNS). Must be lowercase and pass DNS Label (RFC 1123) validation.
endpoints.nodeName (string)
nodeName represents the name of the Node hosting this endpoint. This can be used to determine endpoints local to a Node.
endpoints.targetRef (ObjectReference)
targetRef is a reference to a Kubernetes object that represents this endpoint.
endpoints.zone (string)
zone is the name of the Zone this endpoint exists in.
ports ([]EndpointPort)
Atomic: will be replaced during a merge
ports specifies the list of network ports exposed by each endpoint in this slice. Each port must have a unique name. When ports is empty, it indicates that there are no defined ports. When a port is defined with a nil port value, it indicates "all ports". Each slice may include a maximum of 100 ports.
EndpointPort represents a Port used by an EndpointSlice
ports.port (int32)
port represents the port number of the endpoint. If this is not specified, ports are not restricted and must be interpreted in the context of the specific consumer.
ports.protocol (string)
protocol represents the IP protocol for this port. Must be UDP, TCP, or SCTP. Default is TCP.
ports.name (string)
name represents the name of this port. All ports in an EndpointSlice must have a unique name. If the EndpointSlice is derived from a Kubernetes service, this corresponds to the Service.ports[].name. Name must either be an empty string or pass DNS_LABEL validation: * must be no more than 63 characters long. * must consist of lower case alphanumeric characters or '-'. * must start and end with an alphanumeric character. Default is empty string.
ports.appProtocol (string)
The application protocol for this port. This is used as a hint for implementations to offer richer behavior for protocols that they understand. This field follows standard Kubernetes label syntax. Valid values are either:
Un-prefixed protocol names - reserved for IANA standard service names (as per RFC-6335 and https://www.iana.org/assignments/service-names).
Kubernetes-defined prefixed names:
Other protocols should use implementation-defined prefixed names such as mycompany.com/my-custom-protocol.

2.4 - Ingress
Ingress is a collection of rules that allow inbound connections to reach the endpoints defined by a backend.
apiVersion: networking.k8s.io/v1
import "k8s.io/api/networking/v1"
Ingress
Ingress is a collection of rules that allow inbound connections to reach the endpoints defined by a backend. An Ingress can be configured to give services externally-reachable urls, load balance traffic, terminate SSL, offer name based virtual hosting etc.
IngressSpec
IngressSpec describes the Ingress the user wishes to exist.
defaultBackend (IngressBackend)
defaultBackend is the backend that should handle requests that don't match any rule. If Rules are not specified, DefaultBackend must be specified. If DefaultBackend is not set, the handling of requests that do not match any of the rules will be up to the Ingress controller.
ingressClassName (string)
ingressClassName is the name of an IngressClass cluster resource. Ingress controller implementations use this field to know whether they should be serving this Ingress resource, by a transitive connection (controller -> IngressClass -> Ingress resource). Although the kubernetes.io/ingress.class
annotation (simple constant name) was never formally defined, it was widely supported by Ingress controllers to create a direct binding between Ingress controller and Ingress resources. Newly created Ingress resources should prefer using the field. However, even though the annotation is officially deprecated, for backwards compatibility reasons, ingress controllers should still honor that annotation if present.
rules ([]IngressRule)
Atomic: will be replaced during a merge
rules is a list of host rules used to configure the Ingress. If unspecified, or no rule matches, all traffic is sent to the default backend.
IngressRule represents the rules mapping the paths under a specified host to the related backend services. Incoming requests are first evaluated for a host match, then routed to the backend associated with the matching IngressRuleValue.
rules.host (string)
host is the fully qualified domain name of a network host, as defined by RFC 3986. Note the following deviations from the "host" part of the URI as defined in RFC 3986: 1. IPs are not allowed. Currently an IngressRuleValue can only apply to
the IP in the Spec of the parent Ingress.
2. The :
delimiter is not respected because ports are not allowed.
Currently the port of an Ingress is implicitly :80 for http and
:443 for https.
Both these may change in the future. Incoming requests are matched against the host before the IngressRuleValue. If the host is unspecified, the Ingress routes all traffic based on the specified IngressRuleValue.
host can be "precise" which is a domain name without the terminating dot of a network host (e.g. "foo.bar.com") or "wildcard", which is a domain name prefixed with a single wildcard label (e.g. ".foo.com"). The wildcard character '' must appear by itself as the first DNS label and matches only a single label. You cannot have a wildcard label by itself (e.g. Host == "*"). Requests will be matched against the Host field in the following way: 1. If host is precise, the request matches this rule if the http host header is equal to Host. 2. If host is a wildcard, then the request matches this rule if the http host header is to equal to the suffix (removing the first label) of the wildcard rule.
rules.http (HTTPIngressRuleValue)
HTTPIngressRuleValue is a list of http selectors pointing to backends. In the example: http:///? -> backend where where parts of the url correspond to RFC 3986, this resource will be used to match against everything after the last '/' and before the first '?' or '#'.
rules.http.paths ([]HTTPIngressPath), required
Atomic: will be replaced during a merge
paths is a collection of paths that map requests to backends.
HTTPIngressPath associates a path with a backend. Incoming urls matching the path are forwarded to the backend.
rules.http.paths.backend (IngressBackend), required
backend defines the referenced service endpoint to which the traffic will be forwarded to.
rules.http.paths.pathType (string), required
pathType determines the interpretation of the path matching. PathType can be one of the following values: * Exact: Matches the URL path exactly. * Prefix: Matches based on a URL path prefix split by '/'. Matching is
done on a path element by element basis. A path element refers is the
list of labels in the path split by the '/' separator. A request is a
match for path p if every p is an element-wise prefix of p of the
request path. Note that if the last element of the path is a substring
of the last element in request path, it is not a match (e.g. /foo/bar
matches /foo/bar/baz, but does not match /foo/barbaz).
- ImplementationSpecific: Interpretation of the Path matching is up to
the IngressClass. Implementations can treat this as a separate PathType
or treat it identically to Prefix or Exact path types.
Implementations are required to support all path types.
rules.http.paths.path (string)
path is matched against the path of an incoming request. Currently it can contain characters disallowed from the conventional "path" part of a URL as defined by RFC 3986. Paths must begin with a '/' and must be present when using PathType with value "Exact" or "Prefix".
tls ([]IngressTLS)
Atomic: will be replaced during a merge
tls represents the TLS configuration. Currently the Ingress only supports a single TLS port, 443. If multiple members of this list specify different hosts, they will be multiplexed on the same port according to the hostname specified through the SNI TLS extension, if the ingress controller fulfilling the ingress supports SNI.
IngressTLS describes the transport layer security associated with an ingress.
tls.hosts ([]string)
Atomic: will be replaced during a merge
hosts is a list of hosts included in the TLS certificate. The values in this list must match the name/s used in the tlsSecret. Defaults to the wildcard host setting for the loadbalancer controller fulfilling this Ingress, if left unspecified.
tls.secretName (string)
secretName is the name of the secret used to terminate TLS traffic on port 443. Field is left optional to allow TLS routing based on SNI hostname alone. If the SNI host in a listener conflicts with the "Host" header field used by an IngressRule, the SNI host is used for termination and value of the "Host" header is used for routing.
IngressBackend
IngressBackend describes all endpoints for a given service and port.
resource (TypedLocalObjectReference)
resource is an ObjectRef to another Kubernetes resource in the namespace of the Ingress object. If resource is specified, a service.Name and service.Port must not be specified. This is a mutually exclusive setting with "Service".
service (IngressServiceBackend)
service references a service as a backend. This is a mutually exclusive setting with "Resource".
IngressServiceBackend references a Kubernetes Service as a Backend.
service.name (string), required
name is the referenced service. The service must exist in the same namespace as the Ingress object.
service.port (ServiceBackendPort)
port of the referenced service. A port name or port number is required for a IngressServiceBackend.
ServiceBackendPort is the service port being referenced.
service.port.name (string)
name is the name of the port on the Service. This is a mutually exclusive setting with "Number".
service.port.number (int32)
number is the numerical port number (e.g. 80) on the Service. This is a mutually exclusive setting with "Name".
IngressStatus
IngressStatus describe the current state of the Ingress.
loadBalancer (IngressLoadBalancerStatus)
loadBalancer contains the current status of the load-balancer.
IngressLoadBalancerStatus represents the status of a load-balancer.
loadBalancer.ingress ([]IngressLoadBalancerIngress)
Atomic: will be replaced during a merge
ingress is a list containing ingress points for the load-balancer.
IngressLoadBalancerIngress represents the status of a load-balancer ingress point.
loadBalancer.ingress.hostname (string)
hostname is set for load-balancer ingress points that are DNS based.
loadBalancer.ingress.ip (string)
ip is set for load-balancer ingress points that are IP based.
loadBalancer.ingress.ports ([]IngressPortStatus)
Atomic: will be replaced during a merge
ports provides information about the ports exposed by this LoadBalancer.
IngressPortStatus represents the error condition of a service port
loadBalancer.ingress.ports.port (int32), required
port is the port number of the ingress port.
loadBalancer.ingress.ports.protocol (string), required
protocol is the protocol of the ingress port. The supported values are: "TCP", "UDP", "SCTP"
loadBalancer.ingress.ports.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.

attachRequired indicates this CSI volume driver requires an attach operation (because it implements the CSI ControllerPublishVolume() method), and that the Kubernetes attach detach controller should call the attach volume interface which checks the volumeattachment status and waits until the volume is attached before proceeding to mounting. The CSI external-attacher coordinates with CSI volume driver and updates the volumeattachment status when the attach operation is complete. If the CSIDriverRegistry feature gate is enabled and the value is specified to false, the attach operation will be skipped. Otherwise the attach operation will be called.
This field is immutable.
fsGroupPolicy (string)
fsGroupPolicy defines if the underlying volume supports changing ownership and permission of the volume before being mounted. Refer to the specific FSGroupPolicy values for additional details.
This field was immutable in Kubernetes < 1.29 and now is mutable.
Defaults to ReadWriteOnceWithFSType, which will examine each volume to determine if Kubernetes should modify ownership and permissions of the volume. With the default policy the defined fsGroup will only be applied if a fstype is defined and the volume's access mode contains ReadWriteOnce.
podInfoOnMount (boolean)
podInfoOnMount indicates this CSI volume driver requires additional pod information (like podName, podUID, etc.) during mount operations, if set to true. If set to false, pod information will not be passed on mount. Default is false.
The CSI driver specifies podInfoOnMount as part of driver deployment. If true, Kubelet will pass pod information as VolumeContext in the CSI NodePublishVolume() calls. The CSI driver is responsible for parsing and validating the information passed in as VolumeContext.
The following VolumeContext will be passed if podInfoOnMount is set to true. This list might grow, but the prefix will be used. "csi.storage.k8s.io/pod.name": pod.Name "csi.storage.k8s.io/pod.namespace": pod.Namespace "csi.storage.k8s.io/pod.uid": string(pod.UID) "csi.storage.k8s.io/ephemeral": "true" if the volume is an ephemeral inline volume
defined by a CSIVolumeSource, otherwise "false"
"csi.storage.k8s.io/ephemeral" is a new feature in Kubernetes 1.16. It is only required for drivers which support both the "Persistent" and "Ephemeral" VolumeLifecycleMode. Other drivers can leave pod info disabled and/or ignore this field. As Kubernetes 1.15 doesn't support this field, drivers can only support one mode when deployed on such a cluster and the deployment determines which mode that is, for example via a command line parameter of the driver.
This field was immutable in Kubernetes < 1.29 and now is mutable.
requiresRepublish (boolean)
requiresRepublish indicates the CSI driver wants NodePublishVolume
being periodically called to reflect any possible change in the mounted volume. This field defaults to false.
Note: After a successful initial NodePublishVolume call, subsequent calls to NodePublishVolume should only update the contents of the volume. New mount points will not be seen by a running container.
seLinuxMount (boolean)
seLinuxMount specifies if the CSI driver supports "-o context" mount option.
When "true", the CSI driver must ensure that all volumes provided by this CSI driver can be mounted separately with different -o context
options. This is typical for storage backends that provide volumes as filesystems on block devices or as independent shared volumes. Kubernetes will call NodeStage / NodePublish with "-o context=xyz" mount option when mounting a ReadWriteOncePod volume used in Pod that has explicitly set SELinux context. In the future, it may be expanded to other volume AccessModes. In any case, Kubernetes will ensure that the volume is mounted only with a single SELinux context.
When "false", Kubernetes won't pass any special SELinux mount options to the driver. This is typical for volumes that represent subdirectories of a bigger shared filesystem.
Default is "false".
storageCapacity (boolean)
storageCapacity indicates that the CSI volume driver wants pod scheduling to consider the storage capacity that the driver deployment will report by creating CSIStorageCapacity objects with capacity information, if set to true.
The check can be enabled immediately when deploying a driver. In that case, provisioning new volumes with late binding will pause until the driver deployment has published some suitable CSIStorageCapacity object.
Alternatively, the driver can be deployed with the field unset or false and it can be flipped later when storage capacity information has been published.
This field was immutable in Kubernetes <= 1.22 and now is mutable.
tokenRequests ([]TokenRequest)
Atomic: will be replaced during a merge
tokenRequests indicates the CSI driver needs pods' service account tokens it is mounting volume for to do necessary authentication. Kubelet will pass the tokens in VolumeContext in the CSI NodePublishVolume calls. The CSI driver should parse and validate the following VolumeContext: "csi.storage.k8s.io/serviceAccount.tokens": {
"<audience>": {
"token": <token>,
"expirationTimestamp": <expiration timestamp in RFC3339>,
},
...
}
Note: Audience in each TokenRequest should be different and at most one token is empty string. To receive a new token after expiry, RequiresRepublish can be used to trigger NodePublishVolume periodically.
TokenRequest contains parameters of a service account token.
tokenRequests.audience (string), required
audience is the intended audience of the token in "TokenRequestSpec". It will default to the audiences of kube apiserver.
tokenRequests.expirationSeconds (int64)
expirationSeconds is the duration of validity of the token in "TokenRequestSpec". It has the same default value of "ExpirationSeconds" in "TokenRequestSpec".
volumeLifecycleModes ([]string)
Set: unique values will be kept during a merge
volumeLifecycleModes defines what kind of volumes this CSI volume driver supports. The default if the list is empty is "Persistent", which is the usage defined by the CSI specification and implemented in Kubernetes via the usual PV/PVC mechanism.
The other mode is "Ephemeral". In this mode, volumes are defined inline inside the pod spec with CSIVolumeSource and their lifecycle is tied to the lifecycle of that pod. A driver has to be aware of this because it is only going to get a NodePublishVolume call for such a volume.
For more information about implementing this mode, see https://kubernetes-csi.github.io/docs/ephemeral-local-volumes.html A driver can support one or more of these modes and more modes may be added in the future.
This field is beta. This field is immutable.

3.4 - CSINode
CSINode holds information about all CSI drivers installed on a node.
apiVersion: storage.k8s.io/v1
import "k8s.io/api/storage/v1"
CSINode
CSINode holds information about all CSI drivers installed on a node. CSI drivers do not need to create the CSINode object directly. As long as they use the node-driver-registrar sidecar container, the kubelet will automatically populate the CSINode object for the CSI driver as part of kubelet plugin registration. CSINode has the same name as a node. If the object is missing, it means either there are no CSI Drivers available on the node, or the Kubelet version is low enough that it doesn't create this object. CSINode has an OwnerReference that points to the corresponding node object.
apiVersion: storage.k8s.io/v1
kind: CSINode
metadata (ObjectMeta)
Standard object's metadata. metadata.name must be the Kubernetes node name.
spec (CSINodeSpec), required
spec is the specification of CSINode
CSINodeSpec
CSINodeSpec holds information about the specification of all CSI drivers installed on a node
drivers ([]CSINodeDriver), required
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
drivers is a list of information of all CSI Drivers existing on a node. If all drivers in the list are uninstalled, this can become empty.
CSINodeDriver holds information about the specification of one CSI driver installed on a node
drivers.name (string), required
name represents the name of the CSI driver that this object refers to. This MUST be the same name returned by the CSI GetPluginName() call for that driver.
drivers.nodeID (string), required
nodeID of the node from the driver point of view. This field enables Kubernetes to communicate with storage systems that do not share the same nomenclature for nodes. For example, Kubernetes may refer to a given node as "node1", but the storage system may refer to the same node as "nodeA". When Kubernetes issues a command to the storage system to attach a volume to a specific node, it can use this field to refer to the node name using the ID that the storage system will understand, e.g. "nodeA" instead of "node1". This field is required.
drivers.allocatable (VolumeNodeResources)
allocatable represents the volume resources of a node that are available for scheduling. This field is beta.
VolumeNodeResources is a set of resource limits for scheduling of volumes.
drivers.allocatable.count (int32)
count indicates the maximum number of unique volumes managed by the CSI driver that can be used on a node. A volume that is both attached and mounted on a node is considered to be used once, not twice. The same rule applies for a unique volume that is shared among multiple pods on the same node. If this field is not specified, then the supported number of volumes on this node is unbounded.
drivers.topologyKeys ([]string)
Atomic: will be replaced during a merge
topologyKeys is the list of keys supported by the driver. When a driver is initialized on a cluster, it provides a set of topology keys that it understands (e.g. "company.com/zone", "company.com/region"). When a driver is initialized on a node, it provides the same topology keys along with values. Kubelet will expose these topology keys as labels on its own node object. When Kubernetes does topology aware provisioning, it can use this list to determine which labels it should retrieve from the node object and pass back to the driver. It is possible for different nodes to use different topology keys. This can be empty if driver does not support topology.

3.5 - CSIStorageCapacity
CSIStorageCapacity stores the result of one CSI GetCapacity call.
apiVersion: storage.k8s.io/v1
import "k8s.io/api/storage/v1"
CSIStorageCapacity
CSIStorageCapacity stores the result of one CSI GetCapacity call. For a given StorageClass, this describes the available capacity in a particular topology segment. This can be used when considering where to instantiate new PersistentVolumes.
For example this can express things like: - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1" - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"
The following three cases all imply that no capacity is available for a certain combination: - no object exists with suitable topology and storage class name - such an object exists, but the capacity is unset - such an object exists, but the capacity is zero
The producer of these objects can decide which approach is more suitable.
They are consumed by the kube-scheduler when a CSI driver opts into capacity-aware scheduling with CSIDriverSpec.StorageCapacity. The scheduler compares the MaximumVolumeSize against the requested size of pending volumes to filter out unsuitable nodes. If MaximumVolumeSize is unset, it falls back to a comparison against the less precise Capacity. If that is also unset, the scheduler assumes that capacity is insufficient and tries some other node.
apiVersion: storage.k8s.io/v1
kind: CSIStorageCapacity
metadata (ObjectMeta)
Standard object's metadata. The name has no particular meaning. It must be a DNS subdomain (dots allowed, 253 characters). To ensure that there are no conflicts with other CSI drivers on the cluster, the recommendation is to use csisc-<uuid>, a generated name, or a reverse-domain name which ends with the unique CSI driver name.
Objects are namespaced.
More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
storageClassName (string), required
storageClassName represents the name of the StorageClass that the reported capacity applies to. It must meet the same requirements as the name of a StorageClass object (non-empty, DNS subdomain). If that object no longer exists, the CSIStorageCapacity object is obsolete and should be removed by its creator. This field is immutable.
capacity (Quantity)
capacity is the value reported by the CSI driver in its GetCapacityResponse for a GetCapacityRequest with topology and parameters that match the previous fields.
The semantic is currently (CSI spec 1.2) defined as: The available capacity, in bytes, of the storage that can be used to provision volumes. If not set, that information is currently unavailable.
maximumVolumeSize (Quantity)
maximumVolumeSize is the value reported by the CSI driver in its GetCapacityResponse for a GetCapacityRequest with topology and parameters that match the previous fields.
This is defined since CSI spec 1.4.0 as the largest size that may be used in a CreateVolumeRequest.capacity_range.required_bytes field to create a volume with the same parameters as those in GetCapacityRequest. The corresponding value in the Kubernetes API is ResourceRequirements.Requests in a volume claim.
nodeTopology (LabelSelector)
nodeTopology defines which nodes have access to the storage for which capacity was reported. If not set, the storage is not accessible from any node in the cluster. If empty, the storage is accessible from all nodes. This field is immutable.
CSIStorageCapacityList
CSIStorageCapacityList is a collection of CSIStorageCapacity objects.

3.6 - PersistentVolumeClaim
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
PersistentVolumeClaimSpec
PersistentVolumeClaimSpec describes the common attributes of storage devices and allows a Source for provider-specific attributes
accessModes ([]string)
Atomic: will be replaced during a merge
accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1
selector (LabelSelector)
selector is a label query over volumes to consider for binding.
resources (VolumeResourceRequirements)
resources represents the minimum resources the volume should have. If RecoverVolumeExpansionFailure feature is enabled 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
VolumeResourceRequirements describes the storage resource requirements for a volume.
volumeName (string)
volumeName is the binding reference to the PersistentVolume backing this claim.
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
volumeMode (string)
volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec.
Beta level
dataSource (TypedLocalObjectReference)
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 (TypedObjectReference)
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.
**
dataSourceRef.kind (string), required
Kind is the type of resource being referenced
dataSourceRef.name (string), required
Name is the name of resource being referenced
dataSourceRef.apiGroup (string)
APIGroup is the group for the resource being referenced. If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required.
dataSourceRef.namespace (string)
Namespace is the namespace of resource being referenced Note that when a namespace is specified, a gateway.networking.k8s.io/ReferenceGrant object is required in the referent namespace to allow that namespace's owner to accept the reference. See the ReferenceGrant documentation for details. (Alpha) This field requires the CrossNamespaceVolumeDataSource feature gate to be enabled.
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 value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. 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/ (Beta) Using this field requires the VolumeAttributesClass feature gate to be enabled (off by default).
PersistentVolumeClaimStatus
PersistentVolumeClaimStatus is the current status of a persistent volume claim.
accessModes ([]string)
Atomic: will be replaced during a merge
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 (map[string]string)
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.
This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.
allocatedResources (map[string]Quantity)
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.
This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature.
capacity (map[string]Quantity)
capacity represents the actual resources of the underlying volume.
conditions ([]PersistentVolumeClaimCondition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge

lastTransitionTime is the time the condition transitioned from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
message is the human-readable message indicating details about last transition.
conditions.reason (string)
reason is a unique, this should be a short, machine understandable string that gives the reason for condition's last transition. If it reports "Resizing" that means the underlying persistent volume is being resized.
currentVolumeAttributesClassName (string)
currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using. When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim This is a beta field and requires enabling VolumeAttributesClass feature (off by default).
modifyVolumeStatus (ModifyVolumeStatus)
ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted. This is a beta field and requires enabling VolumeAttributesClass feature (off by default).
ModifyVolumeStatus represents the status object of ControllerModifyVolume operation
modifyVolumeStatus.status (string), required
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.
modifyVolumeStatus.targetVolumeAttributesClassName (string)
targetVolumeAttributesClassName is the name of the VolumeAttributesClass the PVC currently being reconciled
phase (string)
phase represents the current phase of PersistentVolumeClaim.

ephemeral (EphemeralVolumeSource)
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.
Represents an ephemeral volume that is handled by a normal storage driver.
ephemeral.volumeClaimTemplate (PersistentVolumeClaimTemplate)
Will be used to create a stand-alone PVC to provision the volume. 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 \<pod name>-\<volume name>
where \<volume name>
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.
PersistentVolumeClaimTemplate is used to produce PersistentVolumeClaim objects as part of an EphemeralVolumeSource.
ephemeral.volumeClaimTemplate.spec (PersistentVolumeClaimSpec), required
The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here.
ephemeral.volumeClaimTemplate.metadata (ObjectMeta)
May contain labels and annotations that will be copied into the PVC when creating it. No other fields are allowed and will be rejected during validation.
fc (FCVolumeSource)
fc represents a Fibre Channel resource that is attached to a kubelet's host machine and then exposed to the pod.
Represents a Fibre Channel volume. Fibre Channel volumes can only be mounted as read/write once. Fibre Channel volumes support ownership management and SELinux relabeling.

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.
fc.lun (int32)
lun is Optional: FC target lun number
fc.readOnly (boolean)
readOnly is Optional: Defaults to false (read/write). ReadOnly here will force the ReadOnly setting in VolumeMounts.

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) and non-executable files (noexec). Sub path mounts for containers are not supported (spec.containers[].volumeMounts.subpath). The field spec.securityContext.fsGroupChangePolicy has no effect on this volume type.

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. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise.
image.reference (string)
Required: Image or artifact reference to be used. Behaves in the same way as pod.spec.containers[*].image.

driverName (string), required
Name of the CSI driver This field is immutable.
parameters (map[string]string)
parameters hold volume attributes defined by the CSI driver. These values are opaque to the Kubernetes and are passed directly to the CSI driver. The underlying storage provider supports changing these attributes on an existing volume, however the parameters field itself is immutable. To invoke a volume update, a new VolumeAttributesClass should be created with new parameters, and the PersistentVolumeClaim should be updated to reference the new VolumeAttributesClass.
This field is required and must contain at least one key/value pair. The keys cannot be empty, and the maximum number of parameters is 512, with a cumulative max size of 256K. If the CSI driver rejects invalid parameters, the target PersistentVolumeClaim will be set to an "Infeasible" state in the modifyVolumeStatus field.

Audiences are the intendend audiences of the token. A recipient of a token must identify themself with an identifier in the list of audiences of the token, and otherwise should reject the token. A token issued for multiple audiences may be used to authenticate against any of the audiences listed but implies a high degree of trust between the target audiences.
boundObjectRef (BoundObjectReference)
BoundObjectRef is a reference to an object that the token will be bound to. The token will only be valid for as long as the bound object exists. NOTE: The API server's TokenReview endpoint will validate the BoundObjectRef, but other audiences may not. Keep ExpirationSeconds small if you want prompt revocation.
BoundObjectReference is a reference to an object that a token is bound to.
boundObjectRef.apiVersion (string)
API version of the referent.
boundObjectRef.kind (string)
Kind of the referent. Valid kinds are 'Pod' and 'Secret'.
boundObjectRef.name (string)
Name of the referent.
boundObjectRef.uid (string)
UID of the referent.
expirationSeconds (int64)
ExpirationSeconds is the requested duration of validity of the request. The token issuer may return a token with a different validity duration so a client needs to check the 'expiration' field in a response.
TokenRequestStatus
TokenRequestStatus is the result of a token request.
expirationTimestamp (Time), required
ExpirationTimestamp is the time of expiration of the returned token.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
token (string), required
Token is the opaque bearer token.

4.3 - TokenReview
TokenReview attempts to authenticate a token to a known user.
apiVersion: authentication.k8s.io/v1
import "k8s.io/api/authentication/v1"
TokenReview
TokenReview attempts to authenticate a token to a known user. Note: TokenReview requests may be cached by the webhook token authenticator plugin in the kube-apiserver.
TokenReviewSpec
TokenReviewSpec is a description of the token authentication request.
audiences ([]string)
Atomic: will be replaced during a merge
Audiences is a list of the identifiers that the resource server presented with the token identifies as. Audience-aware token authenticators will verify that the token was intended for at least one of the audiences in this list. If no audiences are provided, the audience will default to the audience of the Kubernetes apiserver.
token (string)
Token is the opaque bearer token.
TokenReviewStatus
TokenReviewStatus is the result of the token authentication request.
audiences ([]string)
Atomic: will be replaced during a merge
Audiences are audience identifiers chosen by the authenticator that are compatible with both the TokenReview and token. An identifier is any identifier in the intersection of the TokenReviewSpec audiences and the token's audiences. A client of the TokenReview API that sets the spec.audiences field should validate that a compatible audience identifier is returned in the status.audiences field to ensure that the TokenReview server is audience aware. If a TokenReview returns an empty status.audience field where status.authenticated is "true", the token is valid against the audience of the Kubernetes API server.
authenticated (boolean)
Authenticated indicates that the token was associated with a known user.
error (string)
Error indicates that the token couldn't be checked
user (UserInfo)
User is the UserInfo associated with the provided token.
UserInfo holds the information about the user needed to implement the user.Info interface.
user.extra (map[string][]string)
Any additional information provided by the authenticator.
user.groups ([]string)
Atomic: will be replaced during a merge
The names of groups this user is a part of.
user.uid (string)
A unique value that identifies this user across time. If this user is deleted and another user by the same name is added, they will have different UIDs.
user.username (string)
The name that uniquely identifies this user among all active users.

4.4 - CertificateSigningRequest
CertificateSigningRequest objects provide a mechanism to obtain x509 certificates by submitting a certificate signing request, and having it asynchronously approved and issued.
apiVersion: certificates.k8s.io/v1
import "k8s.io/api/certificates/v1"
CertificateSigningRequest
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.
apiVersion: certificates.k8s.io/v1
kind: CertificateSigningRequest
metadata (ObjectMeta)
spec (CertificateSigningRequestSpec), required
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 (CertificateSigningRequestStatus)
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.
request ([]byte), required
Atomic: will be replaced during a merge
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), required
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:
- "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.
- "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.
- "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:
- Trust distribution: how trust (CA bundles) are distributed.
- Permitted subjects: and behavior when a disallowed subject is requested.
- 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.
- Required, permitted, or forbidden key usages / extended key usages.
- Expiration/certificate lifetime: whether it is fixed by the signer, configurable by the admin.
- Whether or not requests for CA certificates are allowed.
expirationSeconds (int32)
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:
- Old signer that is unaware of the field (such as the in-tree
implementations prior to v1.22)
- Signer whose configured maximum is shorter than the requested duration
- Signer whose configured minimum is longer than the requested duration
The minimum valid value for expirationSeconds is 600, i.e. 10 minutes.
extra (map[string][]string)
extra contains extra attributes of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
groups ([]string)
Atomic: will be replaced during a merge
groups contains group membership of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
uid (string)
uid contains the uid of the user that created the CertificateSigningRequest. Populated by the API server on creation and immutable.
usages ([]string)
Atomic: will be replaced during a merge
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.
certificate ([]byte)
Atomic: will be replaced during a merge
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:
- certificate must contain one or more PEM blocks.
- 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.
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 ([]CertificateSigningRequestCondition)
Map: unique values on key type will be kept during a merge
conditions applied to the request. Known conditions are "Approved", "Denied", and "Failed".
CertificateSigningRequestCondition describes a condition of a CertificateSigningRequest object
conditions.status (string), required
status of the condition, one of True, False, Unknown. Approved, Denied, and Failed conditions may not be "False" or "Unknown".
conditions.type (string), required
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.
conditions.lastTransitionTime (Time)
lastTransitionTime is the time the condition last transitioned from one status to another. If unset, when a new condition type is added or an existing condition's status is changed, the server defaults this to the current time.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.lastUpdateTime (Time)
lastUpdateTime is the time of the last update to this condition
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

4.5 - ClusterTrustBundle v1alpha1
ClusterTrustBundle is a cluster-scoped container for X.
apiVersion: certificates.k8s.io/v1alpha1
import "k8s.io/api/certificates/v1alpha1"
ClusterTrustBundle
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.
apiVersion: certificates.k8s.io/v1alpha1
kind: ClusterTrustBundle
metadata (ObjectMeta)
metadata contains the object metadata.
spec (ClusterTrustBundleSpec), required
spec contains the signer (if any) and trust anchors.
ClusterTrustBundleSpec
ClusterTrustBundleSpec contains the signer and trust anchors.
trustBundle (string), required
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.
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=<the signer name> 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.

apiVersion: authorization.k8s.io/v1
import "k8s.io/api/authorization/v1"
SelfSubjectAccessReview
SelfSubjectAccessReview checks whether or the current user can perform an action. Not filling in a spec.namespace means "in all namespaces". Self is a special case, because users should always be able to check whether they can perform an action
SelfSubjectAccessReviewSpec
SelfSubjectAccessReviewSpec is a description of the access request. Exactly one of ResourceAuthorizationAttributes and NonResourceAuthorizationAttributes must be set
nonResourceAttributes (NonResourceAttributes)
NonResourceAttributes describes information for a non-resource access request
NonResourceAttributes includes the authorization attributes available for non-resource requests to the Authorizer interface
nonResourceAttributes.path (string)
Path is the URL path of the request
nonResourceAttributes.verb (string)
Verb is the standard HTTP verb
resourceAttributes (ResourceAttributes)
ResourceAuthorizationAttributes describes information for a resource access request
ResourceAttributes includes the authorization attributes available for resource requests to the Authorizer interface
resourceAttributes.fieldSelector (FieldSelectorAttributes)
fieldSelector describes the limitation on access based on field. It can only limit access, not broaden it.
This field is alpha-level. To use this field, you must enable the AuthorizeWithSelectors
feature gate (disabled by default).
*FieldSelectorAttributes indicates a field limited access. Webhook authors are encouraged to * ensure rawSelector and requirements are not both set * consider the requirements field if set * not try to parse or consider the rawSelector field if set. This is to avoid another CVE-2022-2880 (i.e. getting different systems to agree on how exactly to parse a query is not something we want), see https://www.oxeye.io/resources/golang-parameter-smuggling-attack for more details. For the SubjectAccessReview endpoints of the kube-apiserver: * If rawSelector is empty and requirements are empty, the request is not limited. * If rawSelector is present and requirements are empty, the rawSelector will be parsed and limited if the parsing succeeds. * If rawSelector is empty and requirements are present, the requirements should be honored * If rawSelector is present and requirements are present, the request is invalid.
resourceAttributes.fieldSelector.rawSelector (string)
rawSelector is the serialization of a field selector that would be included in a query parameter. Webhook implementations are encouraged to ignore rawSelector. The kube-apiserver's *SubjectAccessReview will parse the rawSelector as long as the requirements are not present.
resourceAttributes.fieldSelector.requirements ([]FieldSelectorRequirement)
Atomic: will be replaced during a merge
requirements is the parsed interpretation of a field selector. All requirements must be met for a resource instance to match the selector. Webhook implementations should handle requirements, but how to handle them is up to the webhook. Since requirements can only limit the request, it is safe to authorize as unlimited request if the requirements are not understood.
FieldSelectorRequirement is a selector that contains values, a key, and an operator that relates the key and values.
resourceAttributes.fieldSelector.requirements.key (string), required
key is the field selector key that the requirement applies to.
resourceAttributes.fieldSelector.requirements.operator (string), required
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists, DoesNotExist. The list of operators may grow in the future.
resourceAttributes.fieldSelector.requirements.values ([]string)
Atomic: will be replaced during a merge
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty.
resourceAttributes.group (string)
Group is the API Group of the Resource. "*" means all.
resourceAttributes.labelSelector (LabelSelectorAttributes)
labelSelector describes the limitation on access based on labels. It can only limit access, not broaden it.
This field is alpha-level. To use this field, you must enable the AuthorizeWithSelectors
feature gate (disabled by default).
*LabelSelectorAttributes indicates a label limited access. Webhook authors are encouraged to * ensure rawSelector and requirements are not both set * consider the requirements field if set * not try to parse or consider the rawSelector field if set.

SelfSubjectRulesReview
SelfSubjectRulesReview enumerates the set of actions the current user can perform within a namespace. The returned list of actions may be incomplete depending on the server's authorization mode, and any errors experienced during the evaluation. SelfSubjectRulesReview should be used by UIs to show/hide actions, or to quickly let an end user reason about their permissions. It should NOT Be used by external systems to drive authorization decisions as this raises confused deputy, cache lifetime/revocation, and correctness concerns. SubjectAccessReview, and LocalAccessReview are the correct way to defer authorization decisions to the API server.

Status is filled in by the server and indicates the set of actions a user can perform.
SubjectRulesReviewStatus contains the result of a rules check. This check can be incomplete depending on the set of authorizers the server is configured with and any errors experienced during evaluation. Because authorization rules are additive, if a rule appears in a list it's safe to assume the subject has that permission, even if that list is incomplete.

SubjectAccessReview checks whether or not a user or group can perform an action.
SubjectAccessReviewSpec
SubjectAccessReviewSpec is a description of the access request. Exactly one of ResourceAuthorizationAttributes and NonResourceAuthorizationAttributes must be set
extra (map[string][]string)
Extra corresponds to the user.Info.GetExtra() method from the authenticator. Since that is input to the authorizer it needs a reflection here.

resourceAttributes.fieldSelector (FieldSelectorAttributes)
fieldSelector describes the limitation on access based on field. It can only limit access, not broaden it.
This field is alpha-level. To use this field, you must enable the AuthorizeWithSelectors
feature gate (disabled by default).
*FieldSelectorAttributes indicates a field limited access. Webhook authors are encouraged to * ensure rawSelector and requirements are not both set * consider the requirements field if set * not try to parse or consider the rawSelector field if set. This is to avoid another CVE-2022-2880 (i.e. getting different systems to agree on how exactly to parse a query is not something we want), see https://www.oxeye.io/resources/golang-parameter-smuggling-attack for more details. For the SubjectAccessReview endpoints of the kube-apiserver: * If rawSelector is empty and requirements are empty, the request is not limited. * If rawSelector is present and requirements are empty, the rawSelector will be parsed and limited if the parsing succeeds. * If rawSelector is empty and requirements are present, the requirements should be honored * If rawSelector is present and requirements are present, the request is invalid.

resourceAttributes.fieldSelector.requirements ([]FieldSelectorRequirement)
Atomic: will be replaced during a merge
requirements is the parsed interpretation of a field selector. All requirements must be met for a resource instance to match the selector. Webhook implementations should handle requirements, but how to handle them is up to the webhook. Since requirements can only limit the request, it is safe to authorize as unlimited request if the requirements are not understood.
FieldSelectorRequirement is a selector that contains values, a key, and an operator that relates the key and values.
resourceAttributes.fieldSelector.requirements.key (string), required
key is the field selector key that the requirement applies to.

resourceAttributes.labelSelector (LabelSelectorAttributes)
labelSelector describes the limitation on access based on labels. It can only limit access, not broaden it.
This field is alpha-level. To use this field, you must enable the AuthorizeWithSelectors
feature gate (disabled by default).
*LabelSelectorAttributes indicates a label limited access. Webhook authors are encouraged to * ensure rawSelector and requirements are not both set * consider the requirements field if set * not try to parse or consider the rawSelector field if set.

Allowed is required. True if the action would be allowed, false otherwise.
denied (boolean)
Denied is optional. True if the action would be denied, otherwise false. If both allowed is false and denied is false, then the authorizer has no opinion on whether to authorize the action. Denied may not be true if Allowed is true.
evaluationError (string)
EvaluationError is an indication that some error occurred during the authorization check. It is entirely possible to get an error and be able to continue determine authorization status in spite of it.

FlowSchema
FlowSchema defines the schema of a group of flows. Note that a flow is made up of a set of inbound API requests with similar attributes and is identified by a pair of strings: the name of the FlowSchema and a "flow distinguisher".
FlowSchemaSpec
FlowSchemaSpec describes how the FlowSchema's specification looks like.
distinguisherMethod (FlowDistinguisherMethod)
distinguisherMethod
defines how to compute the flow distinguisher for requests that match this schema. nil
specifies that the distinguisher is disabled and thus will always be the empty string.

type
is the type of flow distinguisher method The supported types are "ByUser" and "ByNamespace". Required.
matchingPrecedence (int32)
matchingPrecedence
is used to choose among the FlowSchemas that match a given request. The chosen FlowSchema is among those with the numerically lowest (which we take to be logically highest) MatchingPrecedence. Each MatchingPrecedence value must be ranged in [1,10000]. Note that if the precedence is not specified, it will be set to 1000 as default.
priorityLevelConfiguration (PriorityLevelConfigurationReference), required
priorityLevelConfiguration

6.4 - NetworkPolicy
NetworkPolicy describes what network traffic is allowed for a set of Pods.
apiVersion: networking.k8s.io/v1
import "k8s.io/api/networking/v1"
NetworkPolicy
NetworkPolicy describes what network traffic is allowed for a set of Pods
NetworkPolicySpec
NetworkPolicySpec provides the specification of a NetworkPolicy
podSelector (LabelSelector), required
podSelector selects the pods to which this NetworkPolicy object applies. The array of ingress rules is applied to any pods selected by this field. Multiple network policies can select the same set of pods. In this case, the ingress rules for each are combined additively. This field is NOT optional and follows standard label selector semantics. An empty podSelector matches all pods in this namespace.
policyTypes ([]string)
Atomic: will be replaced during a merge
policyTypes is a list of rule types that the NetworkPolicy relates to. Valid options are ["Ingress"], ["Egress"], or ["Ingress", "Egress"]. If this field is not specified, it will default based on the existence of ingress or egress rules; policies that contain an egress section are assumed to affect egress, and all policies (whether or not they contain an ingress section) are assumed to affect ingress. If you want to write an egress-only policy, you must explicitly specify policyTypes [ "Egress" ]. Likewise, if you want to write a policy that specifies that no egress is allowed, you must specify a policyTypes value that include "Egress" (since such a policy would not include an egress section and would otherwise default to just [ "Ingress" ]). This field is beta-level in 1.8
ingress ([]NetworkPolicyIngressRule)
Atomic: will be replaced during a merge
ingress is a list of ingress rules to be applied to the selected pods. Traffic is allowed to a pod if there are no NetworkPolicies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic source is the pod's local node, OR if the traffic matches at least one ingress rule across all of the NetworkPolicy objects whose podSelector matches the pod. If this field is empty then this NetworkPolicy does not allow any traffic (and serves solely to ensure that the pods it selects are isolated by default)
NetworkPolicyIngressRule describes a particular set of traffic that is allowed to the pods matched by a NetworkPolicySpec's podSelector. The traffic must match both ports and from.
ingress.from ([]NetworkPolicyPeer)
Atomic: will be replaced during a merge
from is a list of sources which should be able to access the pods selected for this rule. Items in this list are combined using a logical OR operation. If this field is empty or missing, this rule matches all sources (traffic not restricted by source). If this field is present and contains at least one item, this rule allows traffic only if the traffic matches at least one item in the from list.
NetworkPolicyPeer describes a peer to allow traffic to/from. Only certain combinations of fields are allowed
ingress.from.ipBlock (IPBlock)
ipBlock defines policy on a particular IPBlock. If this field is set then neither of the other fields can be.
IPBlock describes a particular CIDR (Ex. "192.168.1.0/24","2001:db8::/64") that is allowed to the pods matched by a NetworkPolicySpec's podSelector. The except entry describes CIDRs that should not be included within this rule.
ingress.from.ipBlock.cidr (string), required
cidr is a string representing the IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64"
ingress.from.ipBlock.except ([]string)
Atomic: will be replaced during a merge
except is a slice of CIDRs that should not be included within an IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64" Except values will be rejected if they are outside the cidr range
ingress.from.namespaceSelector (LabelSelector)
namespaceSelector selects namespaces using cluster-scoped labels. This field follows standard label selector semantics; if present but empty, it selects all namespaces.
If podSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the namespaces selected by namespaceSelector. Otherwise it selects all pods in the namespaces selected by namespaceSelector.
ingress.from.podSelector (LabelSelector)
podSelector is a label selector which selects pods. This field follows standard label selector semantics; if present but empty, it selects all pods.
If namespaceSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the Namespaces selected by NamespaceSelector. Otherwise it selects the pods matching podSelector in the policy's own namespace.
ingress.ports ([]NetworkPolicyPort)
Atomic: will be replaced during a merge
ports is a list of ports which should be made accessible on the pods selected for this rule. Each item in this list is combined using a logical OR. If this field is empty or missing, this rule matches all ports (traffic not restricted by port). If this field is present and contains at least one item, then this rule allows traffic only if the traffic matches at least one port in the list.
NetworkPolicyPort describes a port to allow traffic on
ingress.ports.port (IntOrString)
port represents the port on the given protocol. This can either be a numerical or named port on a pod. If this field is not provided, this matches all port names and numbers. If present, only traffic on the specified protocol AND port will be matched.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
ingress.ports.endPort (int32)
endPort indicates that the range of ports from port to endPort if set, inclusive, should be allowed by the policy. This field cannot be defined if the port field is not defined or if the port field is defined as a named (string) port. The endPort must be equal or greater than port.
ingress.ports.protocol (string)
protocol represents the protocol (TCP, UDP, or SCTP) which traffic must match. If not specified, this field defaults to TCP.
egress ([]NetworkPolicyEgressRule)
Atomic: will be replaced during a merge
egress is a list of egress rules to be applied to the selected pods. Outgoing traffic is allowed if there are no NetworkPolicies selecting the pod (and cluster policy otherwise allows the traffic), OR if the traffic matches at least one egress rule across all of the NetworkPolicy objects whose podSelector matches the pod. If this field is empty then this NetworkPolicy limits all outgoing traffic (and serves solely to ensure that the pods it selects are isolated by default). This field is beta-level in 1.8
NetworkPolicyEgressRule describes a particular set of traffic that is allowed out of pods matched by a NetworkPolicySpec's podSelector. The traffic must match both ports and to. This type is beta-level in 1.8
egress.to ([]NetworkPolicyPeer)
Atomic: will be replaced during a merge
to is a list of destinations for outgoing traffic of pods selected for this rule. Items in this list are combined using a logical OR operation. If this field is empty or missing, this rule matches all destinations (traffic not restricted by destination). If this field is present and contains at least one item, this rule allows traffic only if the traffic matches at least one item in the to list.
NetworkPolicyPeer describes a peer to allow traffic to/from. Only certain combinations of fields are allowed
egress.to.ipBlock (IPBlock)
ipBlock defines policy on a particular IPBlock. If this field is set then neither of the other fields can be.
IPBlock describes a particular CIDR (Ex. "192.168.1.0/24","2001:db8::/64") that is allowed to the pods matched by a NetworkPolicySpec's podSelector. The except entry describes CIDRs that should not be included within this rule.
egress.to.ipBlock.cidr (string), required
cidr is a string representing the IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64"
egress.to.ipBlock.except ([]string)
Atomic: will be replaced during a merge
except is a slice of CIDRs that should not be included within an IPBlock Valid examples are "192.168.1.0/24" or "2001:db8::/64" Except values will be rejected if they are outside the cidr range
egress.to.namespaceSelector (LabelSelector)
namespaceSelector selects namespaces using cluster-scoped labels. This field follows standard label selector semantics; if present but empty, it selects all namespaces.
If podSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the namespaces selected by namespaceSelector. Otherwise it selects all pods in the namespaces selected by namespaceSelector.
egress.to.podSelector (LabelSelector)
podSelector is a label selector which selects pods. This field follows standard label selector semantics; if present but empty, it selects all pods.
If namespaceSelector is also set, then the NetworkPolicyPeer as a whole selects the pods matching podSelector in the Namespaces selected by NamespaceSelector. Otherwise it selects the pods matching podSelector in the policy's own namespace.
egress.ports ([]NetworkPolicyPort)
Atomic: will be replaced during a merge
ports is a list of destination ports for outgoing traffic. Each item in this list is combined using a logical OR. If this field is empty or missing, this rule matches all ports (traffic not restricted by port). If this field is present and contains at least one item, then this rule allows traffic only if the traffic matches at least one port in the list.
NetworkPolicyPort describes a port to allow traffic on
egress.ports.port (IntOrString)
port represents the port on the given protocol. This can either be a numerical or named port on a pod. If this field is not provided, this matches all port names and numbers. If present, only traffic on the specified protocol AND port will be matched.
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
egress.ports.endPort (int32)
endPort indicates that the range of ports from port to endPort if set, inclusive, should be allowed by the policy. This field cannot be defined if the port field is not defined or if the port field is defined as a named (string) port. The endPort must be equal or greater than port.
egress.ports.protocol (string)
protocol represents the protocol (TCP, UDP, or SCTP) which traffic must match. If not specified, this field defaults to TCP.
NetworkPolicyList
NetworkPolicyList is a list of NetworkPolicy objects.

6.5 - PodDisruptionBudget
PodDisruptionBudget is an object to define the max disruption that can be caused to a collection of pods.
apiVersion: policy/v1
import "k8s.io/api/policy/v1"
PodDisruptionBudget
PodDisruptionBudget is an object to define the max disruption that can be caused to a collection of pods
PodDisruptionBudgetSpec
PodDisruptionBudgetSpec is a description of a PodDisruptionBudget.
maxUnavailable (IntOrString)
An eviction is allowed if at most "maxUnavailable" pods selected by "selector" are unavailable after the eviction, i.e. even in absence of the evicted pod. For example, one can prevent all voluntary evictions by specifying 0. This is a mutually exclusive setting with "minAvailable".
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
minAvailable (IntOrString)
An eviction is allowed if at least "minAvailable" pods selected by "selector" will still be available after the eviction, i.e. even in the absence of the evicted pod. So for example you can prevent all voluntary evictions by specifying "100%".
IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.
selector (LabelSelector)
Label query over pods whose evictions are managed by the disruption budget. A null selector will match no pods, while an empty ({}) selector will select all pods within the namespace.
unhealthyPodEvictionPolicy (string)
UnhealthyPodEvictionPolicy defines the criteria for when unhealthy pods should be considered for eviction. Current implementation considers healthy pods, as pods that have status.conditions item with type="Ready",status="True".
Valid policies are IfHealthyBudget and AlwaysAllow. If no policy is specified, the default behavior will be used, which corresponds to the IfHealthyBudget policy.
IfHealthyBudget policy means that running pods (status.phase="Running"), but not yet healthy can be evicted only if the guarded application is not disrupted (status.currentHealthy is at least equal to status.desiredHealthy). Healthy pods will be subject to the PDB for eviction.
AlwaysAllow policy means that all running pods (status.phase="Running"), but not yet healthy are considered disrupted and can be evicted regardless of whether the criteria in a PDB is met. This means perspective running pods of a disrupted application might not get a chance to become healthy. Healthy pods will be subject to the PDB for eviction.
Additional policies may be added in the future. Clients making eviction decisions should disallow eviction of unhealthy pods if they encounter an unrecognized policy in this field.
This field is beta-level. The eviction API uses this field when the feature gate PDBUnhealthyPodEvictionPolicy is enabled (enabled by default).
PodDisruptionBudgetStatus
PodDisruptionBudgetStatus represents information about the status of a PodDisruptionBudget. Status may trail the actual state of a system.
currentHealthy (int32), required
current number of healthy pods
desiredHealthy (int32), required
minimum desired number of healthy pods
disruptionsAllowed (int32), required
Number of pod disruptions that are currently allowed.
expectedPods (int32), required
total number of pods counted by this disruption budget
conditions ([]Condition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
Conditions contain conditions for PDB. The disruption controller sets the DisruptionAllowed condition. The following are known values for the reason field (additional reasons could be added in the future): - SyncFailed: The controller encountered an error and wasn't able to compute
the number of allowed disruptions. Therefore no disruptions are
allowed and the status of the condition will be False.
- InsufficientPods: The number of pods are either at or below the number
required by the PodDisruptionBudget. No disruptions are
allowed and the status of the condition will be False.
- SufficientPods: There are more pods than required by the PodDisruptionBudget.
The condition will be True, and the number of allowed
disruptions are provided by the disruptionsAllowed property.
Condition contains details for one aspect of the current state of this API Resource.
conditions.lastTransitionTime (Time), required
lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string), required
message is a human readable message indicating details about the transition. This may be an empty string.
conditions.reason (string), required
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.
conditions.status (string), required
status of the condition, one of True, False, Unknown.
conditions.type (string), required
type of condition in CamelCase or in foo.example.com/CamelCase.
conditions.observedGeneration (int64)
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.
disruptedPods (map[string]Time)
DisruptedPods contains information about pods whose eviction was processed by the API server eviction subresource handler but has not yet been observed by the PodDisruptionBudget controller. A pod will be in this map from the time when the API server processed the eviction request to the time when the pod is seen by PDB controller as having been marked for deletion (or after a timeout). The key in the map is the name of the pod and the value is the time when the API server processed the eviction request. If the deletion didn't occur and a pod is still there it will be removed from the list automatically by PodDisruptionBudget controller after some time. If everything goes smooth this map should be empty for the most of the time. Large number of entries in the map may indicate problems with pod deletions.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
observedGeneration (int64)
Most recent generation observed when updating this PDB status. DisruptionsAllowed and other status information is valid only if observedGeneration equals to PDB's object generation.
PodDisruptionBudgetList
PodDisruptionBudgetList is a collection of PodDisruptionBudgets.

6.6 - PriorityLevelConfiguration
PriorityLevelConfiguration represents the configuration of a priority level.
apiVersion: flowcontrol.apiserver.k8s.io/v1
import "k8s.io/api/flowcontrol/v1"
PriorityLevelConfiguration
PriorityLevelConfiguration represents the configuration of a priority level.
PriorityLevelConfigurationSpec
PriorityLevelConfigurationSpec specifies the configuration of a priority level.
exempt (ExemptPriorityLevelConfiguration)
exempt
specifies how requests are handled for an exempt priority level. This field MUST be empty if type
is "Limited"
. This field MAY be non-empty if type
is "Exempt"
. If empty and type
is "Exempt"
then the default values for ExemptPriorityLevelConfiguration
apply.
ExemptPriorityLevelConfiguration describes the configurable aspects of the handling of exempt requests. In the mandatory exempt configuration object the values in the fields here can be modified by authorized users, unlike the rest of the spec
.
exempt.lendablePercent (int32)
lendablePercent
prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. This value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows.
LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 )
exempt.nominalConcurrencyShares (int32)
nominalConcurrencyShares
(NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats nominally reserved for this priority level. This DOES NOT limit the dispatching from this priority level but affects the other priority levels through the borrowing mechanism. The server's concurrency limit (ServerCL) is divided among all the priority levels in proportion to their NCS values:
NominalCL(i) = ceil( ServerCL * NCS(i) / sum_ncs ) sum_ncs = sum[priority level k] NCS(k)
Bigger numbers mean a larger nominal concurrency limit, at the expense of every other priority level. This field has a default value of zero.
limited (LimitedPriorityLevelConfiguration)
limited
specifies how requests are handled for a Limited priority level. This field must be non-empty if and only if type
is "Limited"
.
*LimitedPriorityLevelConfiguration specifies how to handle requests that are subject to limits. It addresses two issues:
How are requests for this priority level limited?
What should be done with requests that exceed the limit?*
limited.borrowingLimitPercent (int32)
borrowingLimitPercent
, if present, configures a limit on how many seats this priority level can borrow from other priority levels. The limit is known as this level's BorrowingConcurrencyLimit (BorrowingCL) and is a limit on the total number of seats that this level may borrow at any one time. This field holds the ratio of that limit to the level's nominal concurrency limit. When this field is non-nil, it must hold a non-negative integer and the limit is calculated as follows.
BorrowingCL(i) = round( NominalCL(i) * borrowingLimitPercent(i)/100.0 )
The value of this field can be more than 100, implying that this priority level can borrow a number of seats that is greater than its own nominal concurrency limit (NominalCL). When this field is left nil
, the limit is effectively infinite.
limited.lendablePercent (int32)
lendablePercent
prescribes the fraction of the level's NominalCL that can be borrowed by other priority levels. The value of this field must be between 0 and 100, inclusive, and it defaults to 0. The number of seats that other levels can borrow from this level, known as this level's LendableConcurrencyLimit (LendableCL), is defined as follows.
LendableCL(i) = round( NominalCL(i) * lendablePercent(i)/100.0 )
limited.limitResponse (LimitResponse)
limitResponse
indicates what to do with requests that can not be executed right now
LimitResponse defines how to handle requests that can not be executed right now.
limited.limitResponse.type (string), required
type
is "Queue" or "Reject". "Queue" means that requests that can not be executed upon arrival are held in a queue until they can be executed or a queuing limit is reached. "Reject" means that requests that can not be executed upon arrival are rejected. Required.
limited.limitResponse.queuing (QueuingConfiguration)
queuing
holds the configuration parameters for queuing. This field may be non-empty only if type
is "Queue"
.
QueuingConfiguration holds the configuration parameters for queuing
limited.limitResponse.queuing.handSize (int32)
handSize
is a small positive number that configures the shuffle sharding of requests into queues. When enqueuing a request at this priority level the request's flow identifier (a string pair) is hashed and the hash value is used to shuffle the list of queues and deal a hand of the size specified here. The request is put into one of the shortest queues in that hand. handSize
must be no larger than queues
, and should be significantly smaller (so that a few heavy flows do not saturate most of the queues). See the user-facing documentation for more extensive guidance on setting this field. This field has a default value of 8.
limited.limitResponse.queuing.queueLengthLimit (int32)
queueLengthLimit
is the maximum number of requests allowed to be waiting in a given queue of this priority level at a time; excess requests are rejected. This value must be positive. If not specified, it will be defaulted to 50.
limited.limitResponse.queuing.queues (int32)
queues
is the number of queues for this priority level. The queues exist independently at each apiserver. The value must be positive. Setting it to 1 effectively precludes shufflesharding and thus makes the distinguisher method of associated flow schemas irrelevant. This field has a default value of 64.
limited.nominalConcurrencyShares (int32)
nominalConcurrencyShares
(NCS) contributes to the computation of the NominalConcurrencyLimit (NominalCL) of this level. This is the number of execution seats available at this priority level. This is used both for requests dispatched from this priority level as well as requests dispatched from other priority levels borrowing seats from this level. The server's concurrency limit (ServerCL) is divided among the Limited priority levels in proportion to their NCS values:
NominalCL(i) = ceil( ServerCL * NCS(i) / sum_ncs ) sum_ncs = sum[priority level k] NCS(k)
Bigger numbers mean a larger nominal concurrency limit, at the expense of every other priority level.
If not specified, this field defaults to a value of 30.
Setting this field to zero supports the construction of a "jail" for this priority level that is used to hold some request(s)
type (string), required
type
indicates whether this priority level is subject to limitation on request execution. A value of "Exempt"
means that requests of this priority level are not subject to a limit (and thus are never queued) and do not detract from the capacity made available to other priority levels. A value of "Limited"
means that (a) requests of this priority level are subject to limits and (b) some of the server's limited capacity is made available exclusively to this priority level. Required.
PriorityLevelConfigurationStatus
PriorityLevelConfigurationStatus represents the current state of a "request-priority".
conditions ([]PriorityLevelConfigurationCondition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
conditions
is the current state of "request-priority".
PriorityLevelConfigurationCondition defines the condition of priority level.
conditions.lastTransitionTime (Time)
lastTransitionTime
is the last time the condition transitioned from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
message
is a human-readable message indicating details about last transition.
conditions.reason (string)
reason
is a unique, one-word, CamelCase reason for the condition's last transition.
conditions.status (string)
status
is the status of the condition. Can be True, False, Unknown. Required.
conditions.type (string)
type
is the type of the condition. Required.
PriorityLevelConfigurationList
PriorityLevelConfigurationList is a list of PriorityLevelConfiguration objects.

ValidatingAdmissionPolicy
ValidatingAdmissionPolicy describes the definition of an admission validation policy that accepts or rejects an object without changing it.
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy
metadata (ObjectMeta)
Standard object metadata; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata.
spec (ValidatingAdmissionPolicySpec)
Specification of the desired behavior of the ValidatingAdmissionPolicy.
ValidatingAdmissionPolicySpec is the specification of the desired behavior of the AdmissionPolicy.
spec.auditAnnotations ([]AuditAnnotation)
Atomic: will be replaced during a merge
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.
AuditAnnotation describes how to produce an audit annotation for an API request.
spec.auditAnnotations.key (string), required
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.
spec.auditAnnotations.valueExpression (string), required
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.
spec.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.
spec.matchConditions ([]MatchCondition)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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):
- If ANY matchCondition evaluates to FALSE, the policy is skipped.
- If ALL matchConditions evaluate to TRUE, the policy is evaluated.
- If any matchCondition evaluates to an error (but none are FALSE):
- If failurePolicy=Fail, reject the request
- If failurePolicy=Ignore, the policy is skipped
MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.
spec.matchConditions.expression (string), required
Expression represents the expression which will be evaluated by CEL. Must evaluate to bool. CEL expressions have access to the contents of the AdmissionRequest and Authorizer, organized into CEL 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 admission request(/pkg/apis/admission/types.go#AdmissionRequest). '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

request resource.
Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/
Required.
spec.matchConditions.name (string), required
Name is an identifier for this match condition, used for strategic merging of MatchConditions, as well as providing an identifier for logging purposes. A good name should be descriptive of the associated expression. Name must be a qualified name consisting of alphanumeric characters, '-', '' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')
Required.
spec.matchConstraints (MatchResources)
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.
MatchResources decides whether to run the admission control policy on an object based on whether it meets the match criteria. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
spec.matchConstraints.excludeResourceRules ([]NamedRuleWithOperations)

spec.matchConstraints.excludeResourceRules.operations ([]string)
Atomic: will be replaced during a merge
Operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or * for all of those operations and any future admission operations that are added. If '*' is present, the length of the slice must be one. Required.
spec.matchConstraints.excludeResourceRules.resourceNames ([]string)
Atomic: will be replaced during a merge
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.

For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '' means all resources, but not subresources. 'pods/' means all subresources of pods. '/scale' means all scale subresources. '/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
spec.matchConstraints.excludeResourceRules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "Cluster" means that only cluster-scoped resources will match this rule.

Subresources match the scope of their parent resource. Default is "*".
spec.matchConstraints.matchPolicy (string)
matchPolicy defines how the "MatchResources" 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 ValidatingAdmissionPolicy.
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 ValidatingAdmissionPolicy.
Defaults to "Equivalent"
spec.matchConstraints.namespaceSelector (LabelSelector)
NamespaceSelector decides whether to run the admission control policy 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 policy.
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 policy 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.
spec.matchConstraints.objectSelector (LabelSelector)
ObjectSelector decides whether to run the validation based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the cel validation, 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.
spec.matchConstraints.resourceRules ([]NamedRuleWithOperations)
Atomic: will be replaced during a merge

- 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.
spec.validations.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}".
spec.validations.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)+")"
spec.validations.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.
spec.variables ([]Variable)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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.
Variable is the definition of a variable that is used for composition. A variable is defined as a named expression.
spec.variables.expression (string), required
Expression is the expression that will be evaluated as the value of the variable. The CEL expression has access to the same identifiers as the CEL expressions in Validation.

lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
status.conditions.message (string), required
message is a human readable message indicating details about the transition. This may be an empty string.
status.conditions.reason (string), required
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.
status.conditions.status (string), required
status of the condition, one of True, False, Unknown.
status.conditions.type (string), required
type of condition in CamelCase or in foo.example.com/CamelCase.
status.conditions.observedGeneration (int64)
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.
status.observedGeneration (int64)
The generation observed by the controller.

ValidatingAdmissionPolicyList
ValidatingAdmissionPolicyList is a list of ValidatingAdmissionPolicy.
ValidatingAdmissionPolicyBinding
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.
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

spec.matchResources (MatchResources)
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.
MatchResources decides whether to run the admission control policy on an object based on whether it meets the match criteria. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)

spec.matchResources.namespaceSelector (LabelSelector)
NamespaceSelector decides whether to run the admission control policy 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 policy.
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",

If instead you want to only run the policy 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": [

Default to the empty LabelSelector, which matches everything.
spec.matchResources.objectSelector (LabelSelector)
ObjectSelector decides whether to run the validation based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the cel validation, 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.
spec.matchResources.resourceRules ([]NamedRuleWithOperations)

Namespace API objects are cluster-scoped. "Namespaced" means that only namespaced resources will match this rule. "" means that there are no scope restrictions. Subresources match the scope of their parent resource. Default is "*".
spec.paramRef (ParamRef)
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.
ParamRef describes how to locate the params to be used as input to expressions of rules applied by a policy binding.
spec.paramRef.name (string)
name is the name of the resource being referenced.
One of name
or selector
must be set, but name
and selector
are mutually exclusive properties. If one is set, the other must be unset.
A single parameter used for all admission requests can be configured by setting the name
field, leaving selector
blank, and setting namespace if paramKind
is namespace-scoped.
spec.paramRef.namespace (string)
namespace is the namespace of the referenced resource. Allows limiting the search for params to a specific namespace. Applies to both name
and selector
fields.
A per-namespace parameter may be used by specifying a namespace-scoped paramKind
in the policy and leaving this field empty.
If paramKind
is cluster-scoped, this field MUST be unset. Setting this field results in a configuration error.
If paramKind
is namespace-scoped, the namespace of the object being evaluated for admission will be used when this field is left unset. Take care that if this is left empty the binding must not match any cluster-scoped resources, which will result in an error.
spec.paramRef.parameterNotFoundAction (string)
parameterNotFoundAction
controls the behavior of the binding when the resource exists, and name or selector is valid, but there are no parameters matched by the binding. If the value is set to Allow
, then no matched parameters will be treated as successful validation by the binding. If set to Deny
, then no matched parameters will be subject to the failurePolicy
of the policy.
Allowed values are Allow
or Deny
Required
spec.paramRef.selector (LabelSelector)
selector can be used to match multiple param objects based on their labels. Supply selector: {} to match all resources of the ParamKind.
If multiple params are found, they are all evaluated with the policy expressions and the results are ANDed together.
One of name
or selector
must be set, but name
and selector
are mutually exclusive properties. If one is set, the other must be unset.
spec.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.
spec.validationActions ([]string)
Set: unique values will be kept during a merge
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.

6.8 - ValidatingAdmissionPolicyBinding
ValidatingAdmissionPolicyBinding binds the ValidatingAdmissionPolicy with paramerized resources.
apiVersion: admissionregistration.k8s.io/v1
import "k8s.io/api/admissionregistration/v1"
ValidatingAdmissionPolicyBinding
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.
apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicyBinding
metadata (ObjectMeta)
Standard object metadata; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata.
spec (ValidatingAdmissionPolicyBindingSpec)
Specification of the desired behavior of the ValidatingAdmissionPolicyBinding.
ValidatingAdmissionPolicyBindingSpec is the specification of the ValidatingAdmissionPolicyBinding.
spec.matchResources (MatchResources)
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.
MatchResources decides whether to run the admission control policy on an object based on whether it meets the match criteria. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
spec.matchResources.excludeResourceRules ([]NamedRuleWithOperations)
Atomic: will be replaced during a merge
ExcludeResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy should not care about. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.
spec.matchResources.excludeResourceRules.apiGroups ([]string)
Atomic: will be replaced during a merge
APIGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.
spec.matchResources.excludeResourceRules.apiVersions ([]string)
Atomic: will be replaced during a merge
APIVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.
spec.matchResources.excludeResourceRules.operations ([]string)
Atomic: will be replaced during a merge
Operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or * for all of those operations and any future admission operations that are added. If '*' is present, the length of the slice must be one. Required.
spec.matchResources.excludeResourceRules.resourceNames ([]string)
Atomic: will be replaced during a merge
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
spec.matchResources.excludeResourceRules.resources ([]string)
Atomic: will be replaced during a merge
Resources is a list of resources this rule applies to.
For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '' means all resources, but not subresources. 'pods/' means all subresources of pods. '/scale' means all scale subresources. '/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
spec.matchResources.excludeResourceRules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "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. Subresources match the scope of their parent resource. Default is "*".
spec.matchResources.matchPolicy (string)
matchPolicy defines how the "MatchResources" 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 ValidatingAdmissionPolicy.
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 ValidatingAdmissionPolicy.
Defaults to "Equivalent"
spec.matchResources.namespaceSelector (LabelSelector)
NamespaceSelector decides whether to run the admission control policy 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 policy.
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 policy 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.
spec.matchResources.objectSelector (LabelSelector)
ObjectSelector decides whether to run the validation based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the cel validation, 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.
spec.matchResources.resourceRules ([]NamedRuleWithOperations)
Atomic: will be replaced during a merge
ResourceRules describes what operations on what resources/subresources the ValidatingAdmissionPolicy matches. The policy cares about an operation if it matches any Rule.
NamedRuleWithOperations is a tuple of Operations and Resources with ResourceNames.
spec.matchResources.resourceRules.apiGroups ([]string)
Atomic: will be replaced during a merge
APIGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.
spec.matchResources.resourceRules.apiVersions ([]string)
Atomic: will be replaced during a merge
APIVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.
spec.matchResources.resourceRules.operations ([]string)
Atomic: will be replaced during a merge
Operations is the operations the admission hook cares about - CREATE, UPDATE, DELETE, CONNECT or * for all of those operations and any future admission operations that are added. If '*' is present, the length of the slice must be one. Required.
spec.matchResources.resourceRules.resourceNames ([]string)
Atomic: will be replaced during a merge
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
spec.matchResources.resourceRules.resources ([]string)
Atomic: will be replaced during a merge
Resources is a list of resources this rule applies to.
For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '' means all resources, but not subresources. 'pods/' means all subresources of pods. '/scale' means all scale subresources. '/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
spec.matchResources.resourceRules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "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. Subresources match the scope of their parent resource. Default is "*".
spec.paramRef (ParamRef)
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.
ParamRef describes how to locate the params to be used as input to expressions of rules applied by a policy binding.
spec.paramRef.name (string)
name is the name of the resource being referenced.
One of name
or selector
must be set, but name
and selector
are mutually exclusive properties. If one is set, the other must be unset.
A single parameter used for all admission requests can be configured by setting the name
field, leaving selector
blank, and setting namespace if paramKind
is namespace-scoped.
spec.paramRef.namespace (string)
namespace is the namespace of the referenced resource. Allows limiting the search for params to a specific namespace. Applies to both name
and selector
fields.
A per-namespace parameter may be used by specifying a namespace-scoped paramKind
in the policy and leaving this field empty.
If paramKind
is cluster-scoped, this field MUST be unset. Setting this field results in a configuration error.
If paramKind
is namespace-scoped, the namespace of the object being evaluated for admission will be used when this field is left unset. Take care that if this is left empty the binding must not match any cluster-scoped resources, which will result in an error.
spec.paramRef.parameterNotFoundAction (string)
parameterNotFoundAction
controls the behavior of the binding when the resource exists, and name or selector is valid, but there are no parameters matched by the binding. If the value is set to Allow
, then no matched parameters will be treated as successful validation by the binding. If set to Deny
, then no matched parameters will be subject to the failurePolicy
of the policy.
Allowed values are Allow
or Deny
Required
spec.paramRef.selector (LabelSelector)
selector can be used to match multiple param objects based on their labels. Supply selector: {} to match all resources of the ParamKind.
If multiple params are found, they are all evaluated with the policy expressions and the results are ANDed together.
One of name
or selector
must be set, but name
and selector
are mutually exclusive properties. If one is set, the other must be unset.
spec.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.
spec.validationActions ([]string)
Set: unique values will be kept during a merge
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.
ValidatingAdmissionPolicy
ValidatingAdmissionPolicy describes the definition of an admission validation policy that accepts or rejects an object without changing it.
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
metadata (ObjectMeta)
Standard object metadata; More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata.
spec (ValidatingAdmissionPolicySpec)
Specification of the desired behavior of the ValidatingAdmissionPolicy.
ValidatingAdmissionPolicySpec is the specification of the desired behavior of the AdmissionPolicy.
spec.auditAnnotations ([]AuditAnnotation)
Atomic: will be replaced during a merge
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.
AuditAnnotation describes how to produce an audit annotation for an API request.
spec.auditAnnotations.key (string), required
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.
spec.auditAnnotations.valueExpression (string), required
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.
spec.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.
spec.matchConditions ([]MatchCondition)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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):
- If ANY matchCondition evaluates to FALSE, the policy is skipped.
- If ALL matchConditions evaluate to TRUE, the policy is evaluated.
- If any matchCondition evaluates to an error (but none are FALSE):
- If failurePolicy=Fail, reject the request
- If failurePolicy=Ignore, the policy is skipped
MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.
spec.matchConditions.expression (string), required
Expression represents the expression which will be evaluated by CEL. Must evaluate to bool. CEL expressions have access to the contents of the AdmissionRequest and Authorizer, organized into CEL 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 admission request(/pkg/apis/admission/types.go#AdmissionRequest). '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.
Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/
Required.
spec.matchConditions.name (string), required
Name is an identifier for this match condition, used for strategic merging of MatchConditions, as well as providing an identifier for logging purposes. A good name should be descriptive of the associated expression. Name must be a qualified name consisting of alphanumeric characters, '-', '' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')
Required.
spec.matchConstraints (MatchResources)
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.
MatchResources decides whether to run the admission control policy on an object based on whether it meets the match criteria. The exclude rules take precedence over include rules (if a resource matches both, it is excluded)
spec.matchConstraints.excludeResourceRules ([]NamedRuleWithOperations)
Atomic: will be replaced during a merge

Atomic: will be replaced during a merge
ResourceNames is an optional white list of names that the rule applies to. An empty set means that everything is allowed.
spec.matchConstraints.excludeResourceRules.resources ([]string)

Resources is a list of resources this rule applies to.
For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '' means all resources, but not subresources. 'pods/' means all subresources of pods. '/scale' means all scale subresources. '/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
spec.matchConstraints.excludeResourceRules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "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. Subresources match the scope of their parent resource. Default is "*".
spec.matchConstraints.matchPolicy (string)
matchPolicy defines how the "MatchResources" 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 ValidatingAdmissionPolicy.
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 ValidatingAdmissionPolicy.
Defaults to "Equivalent"
spec.matchConstraints.namespaceSelector (LabelSelector)
NamespaceSelector decides whether to run the admission control policy 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 policy.
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",

spec.matchConstraints.objectSelector (LabelSelector)
ObjectSelector decides whether to run the validation based on if the object has matching labels. objectSelector is evaluated against both the oldObject and newObject that would be sent to the cel validation, 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.

Namespace API objects are cluster-scoped. "Namespaced" means that only namespaced resources will match this rule. "" means that there are no scope restrictions. Subresources match the scope of their parent resource. Default is "*".
spec.paramKind (ParamKind)
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.
ParamKind is a tuple of Group Kind and Version.
spec.paramKind.apiVersion (string)
APIVersion is the API group version the resources belong to. In format of "group/version". Required.

Atomic: will be replaced during a merge
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.
Validation specifies the CEL expression which is used to apply the validation.
spec.validations.expression (string), required
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). - '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.
spec.validations.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}".
spec.validations.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)+")"
spec.validations.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.
spec.variables ([]Variable)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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.
Variable is the definition of a variable that is used for composition. A variable is defined as a named expression.
spec.variables.expression (string), required
Expression is the expression that will be evaluated as the value of the variable. The CEL expression has access to the same identifiers as the CEL expressions in Validation.
spec.variables.name (string), required
Name is the name of the variable. The name must be a valid CEL identifier and unique among all variables. The variable can be accessed in other expressions through variables
For example, if name is "foo", the variable will be available as variables.foo

is needed for this option. This requires spec.preserveUnknownFields to be false, and spec.conversion.webhook to be set.
conversion.webhook (WebhookConversion)
webhook describes how to call the conversion webhook. Required when strategy
is set to "Webhook"
.
WebhookConversion describes how to call a conversion webhook
conversion.webhook.conversionReviewVersions ([]string), required
Atomic: will be replaced during a merge
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.
conversion.webhook.clientConfig (WebhookClientConfig)
clientConfig is the instructions for how to call the webhook if strategy is Webhook
.
WebhookClientConfig contains the information to make a TLS connection with the webhook.
conversion.webhook.clientConfig.caBundle ([]byte)
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.
conversion.webhook.clientConfig.service (ServiceReference)
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
.

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.
conversion.webhook.clientConfig.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.
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.

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:
- anyOf:
- type: integer
- type: string
- allOf:
- anyOf:
- type: integer
- type: string
- ... zero or more
x-kubernetes-list-map-keys ([]string)
Atomic: will be replaced during a merge
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:
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, ...).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
.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:
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.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 ([]ValidationRule)
Patch strategy: merge on key rule
Map: unique values on key rule will be kept during a merge
x-kubernetes-validations describes a list of validation rules written in the CEL expression language.
ValidationRule describes a validation rule written in the CEL expression language.
x-kubernetes-validations.rule (string), required
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.
x-kubernetes-validations.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 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$']
x-kubernetes-validations.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"
x-kubernetes-validations.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)+")"
x-kubernetes-validations.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
.
x-kubernetes-validations.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.
CustomResourceDefinitionStatus
CustomResourceDefinitionStatus indicates the state of the CustomResourceDefinition
acceptedNames (CustomResourceDefinitionNames)
acceptedNames are the names that are actually being used to serve discovery. They may be different than the names in spec.
CustomResourceDefinitionNames indicates the names to serve this CustomResourceDefinition
acceptedNames.kind (string), required
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.
acceptedNames.plural (string), required
plural is the plural name of the resource to serve. The custom resources are served under /apis/\<group>/\<version>/.../\<plural>
. Must match the name of the CustomResourceDefinition (in the form \<names.plural>.\<group>
). Must be all lowercase.
acceptedNames.categories ([]string)
Atomic: will be replaced during a merge
categories is a list of grouped resources this custom resource belongs to (e.g. 'all'). This is published in API discovery documents, and used by clients to support invocations like kubectl get all
.
acceptedNames.listKind (string)
listKind is the serialized kind of the list for this resource. Defaults to "kind
List".
acceptedNames.shortNames ([]string)
Atomic: will be replaced during a merge
shortNames are short names for the resource, exposed in API discovery documents, and used by clients to support invocations like kubectl get \<shortname>
. It must be all lowercase.
acceptedNames.singular (string)
singular is the singular name of the resource. It must be all lowercase. Defaults to lowercased kind
.
conditions ([]CustomResourceDefinitionCondition)
Map: unique values on key type will be kept during a merge
conditions indicate state for particular aspects of a CustomResourceDefinition
CustomResourceDefinitionCondition contains details for the current condition of this pod.
conditions.status (string), required
status is the status of the condition. Can be True, False, Unknown.
conditions.type (string), required
type is the type of the condition. Types include Established, NamesAccepted and Terminating.
conditions.lastTransitionTime (Time)
lastTransitionTime last time the condition transitioned from one status to another.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string)
message is a human-readable message indicating details about last transition.
conditions.reason (string)
reason is a unique, one-word, CamelCase reason for the condition's last transition.
storedVersions ([]string)
Atomic: will be replaced during a merge
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.

7.2 - DeviceClass v1alpha3
DeviceClass is a vendor- or admin-provided resource that contains device configuration and selectors.
apiVersion: resource.k8s.io/v1alpha3
import "k8s.io/api/resource/v1alpha3"
DeviceClass
DeviceClass is a vendor- or admin-provided resource that contains device configuration and selectors. It can be referenced in the device requests of a claim to apply these presets. Cluster scoped.
This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.
apiVersion: resource.k8s.io/v1alpha3
kind: DeviceClass
metadata (ObjectMeta)
Standard object metadata
spec (DeviceClassSpec), required
Spec defines what can be allocated and how to configure it.
This is mutable. Consumers have to be prepared for classes changing at any time, either because they get updated or replaced. Claim allocations are done once based on whatever was set in classes at the time of allocation.
Changing the spec automatically increments the metadata.generation number.
DeviceClassSpec
DeviceClassSpec is used in a [DeviceClass] to define what can be allocated and how to configure it.
config ([]DeviceClassConfiguration)
Atomic: will be replaced during a merge
Config defines configuration parameters that apply to each device that is claimed via this class. Some classses may potentially be satisfied by multiple drivers, so each instance of a vendor configuration applies to exactly one driver.
They are passed to the driver, but are not considered while allocating the claim.
DeviceClassConfiguration is used in DeviceClass.
config.opaque (OpaqueDeviceConfiguration)
Opaque provides driver-specific configuration parameters.
OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.
config.opaque.driver (string), required
Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.
An admission policy provided by the driver developer could use this to decide whether it needs to validate them.
Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.
config.opaque.parameters (RawExtension), required
Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions.
*RawExtension is used to hold extensions in external versions.
To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.
// Internal package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.Object json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// External package:
type MyAPIObject struct {
runtime.TypeMeta json:",inline"
MyPlugin runtime.RawExtension json:"myPlugin"
}
type PluginA struct {
AOption string json:"aOption"
}
// On the wire, the JSON will look something like this:
{
"kind":"MyAPIObject",
"apiVersion":"v1",
"myPlugin": {
"kind":"PluginA",
"aOption":"foo",
},
}
So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*
selectors ([]DeviceSelector)
Atomic: will be replaced during a merge
Each selector must be satisfied by a device which is claimed via this class.
DeviceSelector must have exactly one field set.
selectors.cel (CELDeviceSelector)
CEL contains a CEL expression for selecting a device.
CELDeviceSelector contains a CEL expression for selecting a device.
selectors.cel.expression (string), required
Expression is a CEL expression which evaluates a single device. It must evaluate to true when the device under consideration satisfies the desired criteria, and false when it does not. Any other result is an error and causes allocation of devices to abort.
The expression's input is an object named "device", which carries the following properties:
- driver (string): the name of the driver which defines this device.
- attributes (map[string]object): the device's attributes, grouped by prefix
(e.g. device.attributes["dra.example.com"] evaluates to an object with all
of the attributes which were prefixed by "dra.example.com".
- capacity (map[string]object): the device's capacities, grouped by prefix.
Example: Consider a device with driver="dra.example.com", which exposes two attributes named "model" and "ext.example.com/family" and which exposes one capacity named "modules". This input to this expression would have the following fields:
device.driver
device.attributes["dra.example.com"].model
device.attributes["ext.example.com"].family
device.capacity["dra.example.com"].modules
The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.
The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity.
If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort.
A robust expression should check for the existence of attributes before referencing them.
For ease of use, the cel.bind() function is enabled, and can be used to simplify expressions that access multiple attributes with the same domain. For example:
cel.bind(dra, device.attributes["dra.example.com"], dra.someBool && dra.anotherBool)
suitableNodes (NodeSelector)
Only nodes matching the selector will be considered by the scheduler when trying to find a Node that fits a Pod when that Pod uses a claim that has not been allocated yet and that claim gets allocated through a control plane controller. It is ignored when the claim does not use a control plane controller for allocation.
Setting this field is optional. If unset, all Nodes are candidates.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.
suitableNodes.nodeSelectorTerms ([]NodeSelectorTerm), required
Atomic: will be replaced during a merge
Required. A list of node selector terms. The terms are ORed.
A null or empty node selector term matches no objects. The requirements of them are ANDed. The TopologySelectorTerm type implements a subset of the NodeSelectorTerm.
suitableNodes.nodeSelectorTerms.matchExpressions ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's labels.
suitableNodes.nodeSelectorTerms.matchFields ([]NodeSelectorRequirement)
Atomic: will be replaced during a merge
A list of node selector requirements by node's fields.
DeviceClassList
DeviceClassList is a collection of classes.

device.capacity["dra.example.com"].modules
The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.
The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity.
If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort.
A robust expression should check for the existence of attributes before referencing them.
For ease of use, the cel.bind() function is enabled, and can be used to simplify expressions that access multiple attributes with the same domain. For example:
cel.bind(dra, device.attributes["dra.example.com"], dra.someBool && dra.anotherBool)
suitableNodes (NodeSelector)
Only nodes matching the selector will be considered by the scheduler when trying to find a Node that fits a Pod when that Pod uses a claim that has not been allocated yet and that claim gets allocated through a control plane controller. It is ignored when the claim does not use a control plane controller for allocation.
Setting this field is optional. If unset, all Nodes are candidates.
This is an alpha field and requires enabling the DRAControlPlaneController feature gate.
A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.
suitableNodes.nodeSelectorTerms ([]NodeSelectorTerm), required
Atomic: will be replaced during a merge
Required. A list of node selector terms. The terms are ORed.

webhooks ([]MutatingWebhook)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
Webhooks is a list of webhooks and the affected resources and operations.
MutatingWebhook describes an admission webhook and the resources and operations it applies to.
webhooks.admissionReviewVersions ([]string), required
Atomic: will be replaced during a merge
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.
webhooks.clientConfig (WebhookClientConfig), required
ClientConfig defines how to communicate with the hook. Required
WebhookClientConfig contains the information to make a TLS connection with the webhook
webhooks.clientConfig.caBundle ([]byte)
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.
webhooks.clientConfig.service (ServiceReference)
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
.
ServiceReference holds a reference to Service.legacy.k8s.io
webhooks.clientConfig.service.name (string), required
name
is the name of the service. Required
webhooks.clientConfig.service.namespace (string), required
namespace
is the namespace of the service. Required
webhooks.clientConfig.service.path (string)
path
is an optional URL path which will be sent in any request to this service.
webhooks.clientConfig.service.port (int32)
If specified, the port on the service that hosting webhook. Default to 443 for backward compatibility. port
should be a valid port number (1-65535, inclusive).
webhooks.clientConfig.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.
webhooks.name (string), required
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.
webhooks.sideEffects (string), required
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.
webhooks.failurePolicy (string)
FailurePolicy defines how unrecognized errors from the admission endpoint are handled - allowed values are Ignore or Fail. Defaults to Fail.
webhooks.matchConditions ([]MatchCondition)
Patch strategy: merge on key name
Map: unique values on key name will be kept during a merge
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):
- If ANY matchCondition evaluates to FALSE, the webhook is skipped.
- If ALL matchConditions evaluate to TRUE, the webhook is called.
- 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
MatchCondition represents a condition which must by fulfilled for a request to be sent to a webhook.
webhooks.matchConditions.expression (string), required
Expression represents the expression which will be evaluated by CEL. Must evaluate to bool. CEL expressions have access to the contents of the AdmissionRequest and Authorizer, organized into CEL 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 admission request(/pkg/apis/admission/types.go#AdmissionRequest). '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.
Documentation on CEL: https://kubernetes.io/docs/reference/using-api/cel/
Required.
webhooks.matchConditions.name (string), required
Name is an identifier for this match condition, used for strategic merging of MatchConditions, as well as providing an identifier for logging purposes. A good name should be descriptive of the associated expression. Name must be a qualified name consisting of alphanumeric characters, '-', '' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')
Required.
webhooks.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"
webhooks.namespaceSelector (LabelSelector)
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.
webhooks.objectSelector (LabelSelector)
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.
webhooks.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".
webhooks.rules ([]RuleWithOperations)
Atomic: will be replaced during a merge
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.
RuleWithOperations is a tuple of Operations and Resources. It is recommended to make sure that all the tuple expansions are valid.
webhooks.rules.apiGroups ([]string)
Atomic: will be replaced during a merge
APIGroups is the API groups the resources belong to. '' is all groups. If '' is present, the length of the slice must be one. Required.

Atomic: will be replaced during a merge
APIVersions is the API versions the resources belong to. '' is all versions. If '' is present, the length of the slice must be one. Required.
webhooks.rules.operations ([]string)
Atomic: will be replaced during a merge

webhooks.rules.resources ([]string)
Atomic: will be replaced during a merge
Resources is a list of resources this rule applies to.
For example: 'pods' means pods. 'pods/log' means the log subresource of pods. '' means all resources, but not subresources. 'pods/' means all subresources of pods. '/scale' means all scale subresources. '/*' means all resources and their subresources.
If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
webhooks.rules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "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. Subresources match the scope of their parent resource. Default is "*".
webhooks.timeoutSeconds (int32)
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.

If wildcard is present, the validation rule will ensure resources do not overlap with each other.
Depending on the enclosing object, subresources might not be allowed. Required.
webhooks.rules.scope (string)
scope specifies the scope of this rule. Valid values are "Cluster", "Namespaced", and "" "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. Subresources match the scope of their parent resource. Default is "*".
webhooks.timeoutSeconds (int32)
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.

8 - Cluster Resources
8.1 - APIService
APIService represents a server for a particular GroupVersion.
apiVersion: apiregistration.k8s.io/v1
import "k8s.io/kube-aggregator/pkg/apis/apiregistration/v1"
APIService
APIService represents a server for a particular GroupVersion. Name must be "version.group".
APIServiceSpec
APIServiceSpec contains information for locating and communicating with a server. Only https is supported, though you are able to disable certificate verification.
groupPriorityMinimum (int32), required
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
versionPriority (int32), required
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.

ServiceReference holds a reference to Service.legacy.k8s.io
service.name (string)
Name is the name of the service
service.namespace (string)
Namespace is the namespace of the service
service.port (int32)
If specified, the port on the service that hosting webhook. Default to 443 for backward compatibility. port

8.6 - LeaseCandidate v1alpha1
LeaseCandidate defines a candidate for a Lease object.
apiVersion: coordination.k8s.io/v1alpha1
import "k8s.io/api/coordination/v1alpha1"
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.
LeaseCandidateSpec
LeaseCandidateSpec is a specification of a Lease.
leaseName (string), required
LeaseName is the name of the lease for which this candidate is contending. This field is immutable.
preferredStrategies ([]string), required
Atomic: will be replaced during a merge
PreferredStrategies indicates the list of strategies for picking the leader for coordinated leader election. The list is ordered, and the first strategy supersedes all other strategies. The list is used by coordinated leader election to make a decision about the final election strategy. This follows as - If all clients have strategy X as the first element in this list, strategy X will be used. - If a candidate has strategy [X] and another candidate has strategy [Y, X], Y supersedes X and strategy Y
will be used.
- If a candidate has strategy [X, Y] and another candidate has strategy [Y, X], this is a user error and leader
election will not operate the Lease until resolved.
(Alpha) Using this field requires the CoordinatedLeaderElection feature gate to be enabled.
binaryVersion (string)
BinaryVersion is the binary version. It must be in a semver format without leading v
. This field is required when strategy is "OldestEmulationVersion"
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"
pingTime (MicroTime)
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.
MicroTime is version of Time with microsecond level precision.
renewTime (MicroTime)
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.
MicroTime is version of Time with microsecond level precision.

NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22
config.active.configMap (ConfigMapNodeConfigSource)
ConfigMap is a reference to a Node's ConfigMap

config.assigned (NodeConfigSource)
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.
NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22
config.assigned.configMap (ConfigMapNodeConfigSource)
ConfigMap is a reference to a Node's ConfigMap

UID is the metadata.UID of the referenced ConfigMap. This field is forbidden in Node.Spec, and required in Node.Status.
config.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.
config.lastKnownGood (NodeConfigSource)
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.
NodeConfigSource specifies a source of node configuration. Exactly one subfield (excluding metadata) must be non-nil. This API is deprecated since 1.22
config.lastKnownGood.configMap (ConfigMapNodeConfigSource)

8.9 - RuntimeClass
RuntimeClass defines a class of container runtime supported in the cluster.
apiVersion: node.k8s.io/v1
import "k8s.io/api/node/v1"
RuntimeClass
RuntimeClass defines a class of container runtime supported in the cluster. The RuntimeClass is used to determine which container runtime is used to run all containers in a pod. RuntimeClasses are manually defined by a user or cluster provisioner, and referenced in the PodSpec. The Kubelet is responsible for resolving the RuntimeClassName reference before running the pod. For more details, see https://kubernetes.io/docs/concepts/containers/runtime-class/
apiVersion: node.k8s.io/v1
kind: RuntimeClass
metadata (ObjectMeta)
More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
handler (string), required
handler specifies the underlying runtime and configuration that the CRI implementation will use to handle pods of this class. The possible values are specific to the node & CRI configuration. It is assumed that all handlers are available on every node, and handlers of the same name are equivalent on every node. For example, a handler called "runc" might specify that the runc OCI runtime (using native Linux containers) will be used to run the containers in a pod. The Handler must be lowercase, conform to the DNS Label (RFC 1123) requirements, and is immutable.
overhead (Overhead)
overhead represents the resource overhead associated with running a pod for a given RuntimeClass. For more details, see
https://kubernetes.io/docs/concepts/scheduling-eviction/pod-overhead/
Overhead structure represents the resource overhead associated with running a pod.
scheduling (Scheduling)
scheduling holds the scheduling constraints to ensure that pods running with this RuntimeClass are scheduled to nodes that support it. If scheduling is nil, this RuntimeClass is assumed to be supported by all nodes.
Scheduling specifies the scheduling constraints for nodes supporting a RuntimeClass.
scheduling.nodeSelector (map[string]string)
nodeSelector lists labels that must be present on nodes that support this RuntimeClass. Pods using this RuntimeClass can only be scheduled to a node matched by this selector. The RuntimeClass nodeSelector is merged with a pod's existing nodeSelector. Any conflicts will cause the pod to be rejected in admission.
scheduling.tolerations ([]Toleration)
Atomic: will be replaced during a merge
tolerations are appended (excluding duplicates) to pods running with this RuntimeClass during admission, effectively unioning the set of nodes tolerated by the pod and the RuntimeClass.
The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .
scheduling.tolerations.key (string)
Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.
scheduling.tolerations.operator (string)
Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.
scheduling.tolerations.value (string)
Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.
scheduling.tolerations.effect (string)
Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.
scheduling.tolerations.tolerationSeconds (int64)
TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

8.10 - ServiceCIDR v1beta1
ServiceCIDR defines a range of IP addresses using CIDR format (e.
apiVersion: networking.k8s.io/v1beta1
import "k8s.io/api/networking/v1beta1"
ServiceCIDR
ServiceCIDR defines a range of IP addresses using CIDR format (e.g. 192.168.0.0/24 or 2001:db2::/64). This range is used to allocate ClusterIPs to Service objects.
ServiceCIDRSpec
ServiceCIDRSpec define the CIDRs the user wants to use for allocating ClusterIPs for Services.
cidrs ([]string)
Atomic: will be replaced during a merge
CIDRs defines the IP blocks in CIDR notation (e.g. "192.168.0.0/24" or "2001:db8::/64") from which to assign service cluster IPs. Max of two CIDRs is allowed, one of each IP family. This field is immutable.
ServiceCIDRStatus
ServiceCIDRStatus describes the current state of the ServiceCIDR.
conditions ([]Condition)
Patch strategy: merge on key type
Map: unique values on key type will be kept during a merge
conditions holds an array of metav1.Condition that describe the state of the ServiceCIDR. Current service state
Condition contains details for one aspect of the current state of this API Resource.
conditions.lastTransitionTime (Time), required
lastTransitionTime is the last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
conditions.message (string), required
message is a human readable message indicating details about the transition. This may be an empty string.
conditions.reason (string), required
reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty.
conditions.status (string), required
status of the condition, one of True, False, Unknown.
conditions.type (string), required
type of condition in CamelCase or in foo.example.com/CamelCase.
conditions.observedGeneration (int64)
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.
ServiceCIDRList
ServiceCIDRList contains a list of ServiceCIDR objects.

9 - Common Definitions
9.1 - DeleteOptions
DeleteOptions may be provided when deleting an API object.
import "k8s.io/apimachinery/pkg/apis/meta/v1"
DeleteOptions may be provided when deleting an API object.
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
dryRun ([]string)
Atomic: will be replaced during a merge
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 (int64)
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.
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
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.
preconditions (Preconditions)
Must be fulfilled before a deletion is carried out. If not possible, a 409 Conflict status will be returned.
Preconditions must be fulfilled before an operation (update, delete, etc.) is carried out.
preconditions.resourceVersion (string)
Specifies the target ResourceVersion
preconditions.uid (string)
Specifies the target UID.
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.
9.2 - LabelSelector
A label selector is a label query over a set of resources.
import "k8s.io/apimachinery/pkg/apis/meta/v1"
A label selector is a label query over a set of resources. The result of matchLabels and matchExpressions are ANDed. An empty label selector matches all objects. A null label selector matches no objects.
matchExpressions ([]LabelSelectorRequirement)
Atomic: will be replaced during a merge
matchExpressions is a list of label selector requirements. The requirements are ANDed.
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
matchExpressions.key (string), required
key is the label key that the selector applies to.
matchExpressions.operator (string), required
operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist.
matchExpressions.values ([]string)
Atomic: will be replaced during a merge
values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch.
matchLabels (map[string]string)
matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed.
9.3 - ListMeta
ListMeta describes metadata that synthetic resources must have, including lists and various status objects.
import "k8s.io/apimachinery/pkg/apis/meta/v1"
ListMeta describes metadata that synthetic resources must have, including lists and various status objects. A resource may have only one of {ObjectMeta, ListMeta}.
continue (string)
continue may be set if the user set a limit on the number of items returned, and indicates that the server has more data available. The value is opaque and may be used to issue another request to the endpoint that served this list to retrieve the next set of available objects. Continuing a consistent list may not be possible if the server configuration has changed or more than a few minutes have passed. The resourceVersion field returned when using this continue value will be identical to the value in the first response, unless you have received this token from an error message.
remainingItemCount (int64)
remainingItemCount is the number of subsequent items in the list which are not included in this list response. If the list request contained label or field selectors, then the number of remaining items is unknown and the field will be left unset and omitted during serialization. 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 this field will be left unset and omitted during serialization. Servers older than v1.15 do not set this field. The intended use of the remainingItemCount is estimating the size of a collection. Clients should not rely on the remainingItemCount to be set or to be exact.
resourceVersion (string)
String that identifies the server's internal version of this object that can be used by clients to determine when objects have changed. Value must be treated as opaque by clients and passed unmodified back to the server. Populated by the system. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency
selfLink (string)
Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.
9.4 - LocalObjectReference
LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace.
import "k8s.io/api/core/v1"
LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace.
9.5 - NodeSelectorRequirement
A node selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
import "k8s.io/api/core/v1"
A node selector requirement is a selector that contains values, a key, and an operator that relates the key and values.
key (string), required
The label key that the selector applies to.
operator (string), required
Represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists, DoesNotExist. Gt, and Lt.
values ([]string)
Atomic: will be replaced during a merge
An array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. If the operator is Gt or Lt, the values array must have a single element, which will be interpreted as an integer. This array is replaced during a strategic merge patch.
9.6 - ObjectFieldSelector
ObjectFieldSelector selects an APIVersioned field of an object.
import "k8s.io/api/core/v1"
ObjectFieldSelector selects an APIVersioned field of an object.
fieldPath (string), required
Path of the field to select in the specified API version.
apiVersion (string)
Version of the schema the FieldPath is written in terms of, defaults to "v1".
9.7 - ObjectMeta
ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.
import "k8s.io/apimachinery/pkg/apis/meta/v1"
ObjectMeta is metadata that all persisted resources must have, which includes all objects users must create.
name (string)
Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names
generateName (string)
GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server.
If this field is specified and the generated name exists, the server will return a 409.
Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency
namespace (string)
Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.
Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces
labels (map[string]string)
Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels
annotations (map[string]string)
Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/annotations
System
finalizers ([]string)
Set: unique values will be kept during a merge
Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed. Finalizers may be processed and removed in any order. Order is NOT enforced because it introduces significant risk of stuck finalizers. finalizers is a shared field, any actor with permission can reorder it. If the finalizer list is processed in order, then this can lead to a situation in which the component responsible for the first finalizer in the list is waiting for a 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.
managedFields ([]ManagedFieldsEntry)
Atomic: will be replaced during a merge
ManagedFields maps workflow-id and version to the set of fields that are managed by that workflow. This is mostly for internal housekeeping, and users typically shouldn't need to set or understand this field. A workflow can be the user's name, a controller's name, or the name of a specific apply path like "ci-cd". The set of fields is always in the version that the workflow used when modifying the object.
ManagedFieldsEntry is a workflow-id, a FieldSet and the group version of the resource that the fieldset applies to.
managedFields.apiVersion (string)
APIVersion defines the version of this resource that this field set applies to. The format is "group/version" just like the top-level APIVersion field. It is necessary to track the version of a field set because it cannot be automatically converted.
managedFields.fieldsType (string)
FieldsType is the discriminator for the different fields format and version. There is currently only one possible value: "FieldsV1"
managedFields.fieldsV1 (FieldsV1)
FieldsV1 holds the first JSON version format as described in the "FieldsV1" type.
*FieldsV1 stores a set of fields in a data structure like a Trie, in JSON format.
Each key is either a '.' representing the field itself, and will always map to an empty set, or a string representing a sub-field or item. The string will follow one of these four formats: 'f:', where is the name of a field in a struct, or key in a map 'v:', where is the exact json formatted value of a list item 'i:', where is position of a item in a list 'k:', where is a map of a list item's key fields to their unique values If a key maps to an empty Fields value, the field that key represents is part of the set.
The exact format is defined in sigs.k8s.io/structured-merge-diff*
managedFields.manager (string)
Manager is an identifier of the workflow managing these fields.
managedFields.operation (string)
Operation is the type of operation which lead to this ManagedFieldsEntry being created. The only valid values for this field are 'Apply' and 'Update'.
managedFields.subresource (string)
Subresource is the name of the subresource used to update that object, or empty string if the object was updated through the main resource. The value of this field is used to distinguish between managers, even if they share the same name. For example, a status update will be distinct from a regular update using the same manager name. Note that the APIVersion field is not related to the Subresource field and it always corresponds to the version of the main resource.
managedFields.time (Time)
Time is the timestamp of when the ManagedFields entry was added. The timestamp will also be updated if a field is added, the manager changes any of the owned fields value or removes a field. The timestamp does not update when a field is removed from the entry because another manager took it over.
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
ownerReferences ([]OwnerReference)
Patch strategy: merge on key uid
Map: unique values on key uid will be kept during a merge
List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.
OwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field.
Read-only
creationTimestamp (Time)
CreationTimestamp is a timestamp representing the server time when this object was created. It is not guaranteed to be set in happens-before order across separate operations. Clients may not set this value. It is represented in RFC3339 form and is in UTC.
Populated by the system. Read-only. Null for lists. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
deletionGracePeriodSeconds (int64)
Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set. May only be shortened. Read-only.
deletionTimestamp (Time)
DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted. This field is set by the server when a graceful deletion is requested by the user, and is not directly settable by a client. The resource is expected to be deleted (no longer visible from resource lists, and not reachable by name) after the time in this field, once the finalizers list is empty. As long as the finalizers list contains items, deletion is blocked. Once the deletionTimestamp is set, this value may not be unset or be set further into the future, although it may be shortened or the resource may be deleted prior to this time. For example, a user may request that a pod is deleted in 30 seconds. The Kubelet will react by sending a graceful termination signal to the containers in the pod. After that 30 seconds, the Kubelet will send a hard termination signal (SIGKILL) to the container and after cleanup, remove the pod from the API. In the presence of network partitions, this object may still exist after this timestamp, until an administrator or automated process can determine the resource is fully terminated. If not set, graceful deletion of the object has not been requested.
Populated by the system when a graceful deletion is requested. Read-only. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.
generation (int64)
A sequence number representing a specific generation of the desired state. Populated by the system. Read-only.
resourceVersion (string)
An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed. May be used for optimistic concurrency, change detection, and the watch operation on a resource or set of resources. Clients must treat these values as opaque and passed unmodified back to the server. They may only be valid for a particular resource or set of resources.
Populated by the system. Read-only. Value must be treated as opaque by clients and . More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency
selfLink (string)
Deprecated: selfLink is a legacy read-only field that is no longer populated by the system.
uid (string)
UID is the unique in time and space value for this object. It is typically generated by the server on successful creation of a resource and is not allowed to change on PUT operations.
Populated by the system. Read-only. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids
9.8 - ObjectReference

9.9 - Patch
Patch is provided to give a concrete name and type to the Kubernetes PATCH request body.
import "k8s.io/apimachinery/pkg/apis/meta/v1"
Patch is provided to give a concrete name and type to the Kubernetes PATCH request body.
9.10 - Quantity
Quantity is a fixed-point representation of a number.
import "k8s.io/apimachinery/pkg/api/resource"
Quantity is a fixed-point representation of a number. It provides convenient marshaling/unmarshaling in JSON and YAML, in addition to String() and AsInt64() accessors.
The serialization format is:
\<quantity> ::= \<signedNumber>\<suffix>
(Note that \<suffix> may be empty, from the "" case in \<decimalSI>.)
\<digit> ::= 0 | 1 | ... | 9 \<digits> ::= \<digit> | \<digit>\<digits> \<number> ::= \<digits> | \<digits>.\<digits> | \<digits>. | .\<digits> \<sign> ::= "+" | "-" \<signedNumber> ::= \<number> | \<sign>\<number> \<suffix> ::= \<binarySI> | \<decimalExponent> | \<decimalSI> \<binarySI> ::= Ki | Mi | Gi | Ti | Pi | Ei
(International System of units; See: http://physics.nist.gov/cuu/Units/binary.html)
\<decimalSI> ::= m | "" | k | M | G | T | P | E
(Note that 1024 = 1Ki but 1000 = 1k; I didn't choose the capitalization.)
\<decimalExponent> ::= "e" \<signedNumber> | "E" \<signedNumber>
No matter which of the three exponent forms is used, no quantity may represent a number greater than 2^63-1 in magnitude, nor may it have more than 3 decimal places. Numbers larger or more precise will be capped or rounded up. (E.g.: 0.1m will rounded up to 1m.) This may be extended in the future if we require larger or smaller quantities.
When a Quantity is parsed from a string, it will remember the type of suffix it had, and will use the same type again when it is serialized.
Before serializing, Quantity will be put in "canonical form". This means that Exponent/suffix will be adjusted up or down (with a corresponding increase or decrease in Mantissa) such that:
- No precision is lost - No fractional digits will be emitted - The exponent (or suffix) is as large as possible.
The sign will be omitted unless the number is negative.
Examples:
- 1.5 will be serialized as "1500m" - 1.5Gi will be serialized as "1536Mi"
Note that the quantity will NEVER be internally represented by a floating point number. That is the whole point of this exercise.
Non-canonical values will still parse as long as they are well formed, but will be re-emitted in their canonical form. (So always use canonical form, or don't diff.)
This format is intended to make it difficult to use these numbers without writing some sort of special handling code in the hopes that that will cause implementors to also use a fixed point implementation.
9.11 - ResourceFieldSelector
ResourceFieldSelector represents container resources (cpu, memory) and their output format.
import "k8s.io/api/core/v1"
ResourceFieldSelector represents container resources (cpu, memory) and their output format

import "k8s.io/apimachinery/pkg/apis/meta/v1"
Status is a return value for calls that don't return other objects.
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

StatusDetails is a set of additional properties that MAY be set by the server to provide additional information about a response. The Reason field of a Status object defines what attributes will be set. Clients must ignore fields that do not match the defined type of each attribute, and should assume that any attribute may be empty, invalid, or under defined.
details.causes ([]StatusCause)
Atomic: will be replaced during a merge
The Causes array includes more details associated with the StatusReason failure. Not all StatusReasons may provide detailed causes.
StatusCause provides more information about an api.Status failure, including cases when multiple errors are encountered.
details.causes.field (string)
The field of the resource that has caused this error, as named by its JSON serialization. May include dot and postfix notation for nested attributes. Arrays are zero-indexed. Fields may appear more than once in an array of causes due to fields having multiple errors. Optional.
Examples:
"name" - the field "name" on the current resource
"items[0].name" - the field "name" on the first array entry in "items"
details.causes.message (string)
A human-readable description of the cause of the error. This field may be presented as-is to a reader.

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
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
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
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.
fieldSelector
A selector to restrict the list of returned objects by their fields. Defaults to everything.
fieldValidation
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
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
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.
labelSelector
A selector to restrict the list of returned objects by their labels. Defaults to everything.
limit
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.
namespace
object name and auth scope, such as for teams and projects
pretty
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).
propagationPolicy
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
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
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
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.
timeoutSeconds
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.
watch
Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
