kubectl autoscale
Synopsis
Creates an autoscaler that automatically chooses and sets the number of pods that run in a Kubernetes cluster.
Looks up a deployment, replica set, stateful set, or replication controller by name and creates an autoscaler that uses the given resource as a reference. An autoscaler can automatically increase or decrease number of pods deployed within the system as needed.
kubectl autoscale (-f FILENAME | TYPE NAME | TYPE/NAME) [--min=MINPODS] --max=MAXPODS [--cpu-percent=CPU]
Examples
# Auto scale a deployment "foo", with the number of pods between 2 and 10, no target CPU utilization specified so a default autoscaling policy will be used
kubectl autoscale deployment foo --min=2 --max=10
# Auto scale a replication controller "foo", with the number of pods between 1 and 5, target CPU utilization at 80%
kubectl autoscale rc foo --max=5 --cpu-percent=80
Options
| --allow-missing-template-keys Default: true | |
If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. | |
| --cpu-percent int32 Default: -1 | |
The target average CPU utilization (represented as a percent of requested CPU) over all the pods. If it's not specified or negative, a default autoscaling policy will be used. | |
| --dry-run string[="unchanged"] Default: "none" | |
Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource. | |
| --field-manager string Default: "kubectl-autoscale" | |
Name of the manager used to track field ownership. | |
| -f, --filename strings | |
Filename, directory, or URL to files identifying the resource to autoscale. | |
| -h, --help | |
help for autoscale | |
| -k, --kustomize string | |
Process the kustomization directory. This flag can't be used together with -f or -R. | |
| --max int32 Default: -1 | |
The upper limit for the number of pods that can be set by the autoscaler. Required. | |
| --min int32 Default: -1 | |
The lower limit for the number of pods that can be set by the autoscaler. If it's not specified or negative, the server will apply a default value. | |
| --name string | |
The name for the newly created object. If not specified, the name of the input resource will be used. | |
| -o, --output string | |

| -R, --recursive | |
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory. | |
| --save-config | |
If true, the configuration of current object will be saved in its annotation. Otherwise, the annotation will be unchanged. This flag is useful when you want to perform kubectl apply on this object in the future. | |
| --show-managed-fields | |
If true, keep the managedFields when printing objects in JSON or YAML format. | |
| --template string | |
Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]. | |
