kubectl autoscale — Auto-scale a Deployment, ReplicaSet, or ReplicationController

Synopsis

kubectl autoscale [Options]

Description

Creates an autoscaler that automatically chooses and sets the number of pods that run in a kubernetes cluster.

Looks up a Deployment, ReplicaSet, or ReplicationController 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.

Options

--cpu-percent=-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=false
If true, only print the object that would be sent, without sending it.
-f, --filename=[]
Filename, directory, or URL to a file identifying the resource to autoscale.
--generator="horizontalpodautoscaler/v1"
The name of the API generator to use. Currently there is only 1 generator.
--include-extended-apis=true
If true, include definitions of new APIs via calls to the API server. [default true]
--max=-1
The upper limit for the number of pods that can be set by the autoscaler. Required.
--min=-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=""
The name for the newly created object. If not specified, the name of the input resource will be used.
--no-headers=false
When using the default output, don't print headers.
-o, --output=""
Output format. One of: json|yaml|wide|name|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See golang template [ ⟨http://golang.org/pkg/text/template/#pk…⟩] and jsonpath template [ ⟨http://releases.k8s.io/release-1.3/docs…⟩].
--output-version=""
Output the formatted object with the given group version (for ex: 'extensions/v1beta1').
--record=false
Record current kubectl command in the resource annotation.
-R, --recursive=false
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
--save-config=false
If true, the configuration of current object will be saved in its annotation. This is useful when you want to perform kubectl apply on this object in the future.
-a, --show-all=false
When printing, show all resources (default hide terminated pods.)
--show-labels=false
When printing, show all labels as the last column (default hide labels column)
--sort-by=""
If non-empty, sort list types using this field specification. The field specification is expressed as a JSONPath expression (e.g. '{.metadata.name}'). The field in the API resource specified by this JSONPath expression must be an integer or a string.
--template=""
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/#pk…⟩].

Options Inherited from Parent Commands

--alsologtostderr=false
log to standard error as well as files

--api-version=""
DEPRECATED: The API version to use when talking to the server

--as=""
Username to impersonate for the operation.

--certificate-authority=""
Path to a cert. file for the certificate authority.

--client-certificate=""
Path to a client certificate file for TLS.

--client-key=""
Path to a client key file for TLS.

--cluster=""
The name of the kubeconfig cluster to use

--context=""
The name of the kubeconfig context to use

--insecure-skip-tls-verify=false
If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.

--kubeconfig=""
Path to the kubeconfig file to use for CLI requests.

--log-backtrace-at=:0
when logging hits line file:N, emit a stack trace

--log-dir=""
If non-empty, write log files in this directory

--log-flush-frequency=5s
Maximum number of seconds between log flushes

--logtostderr=true
log to standard error instead of files

--match-server-version=false
Require server version to match client version

--namespace=""
If present, the namespace scope for this CLI request.

--password=""
Password for basic authentication to the API server.

-s, --server=""
The address and port of the Kubernetes API server

--stderrthreshold=2
logs at or above this threshold go to stderr

--token=""
Bearer token for authentication to the API server.

--user=""
The name of the kubeconfig user to use

--username=""
Username for basic authentication to the API server.

--v=0
log level for V logs

--vmodule=
comma-separated list of pattern=N settings for file-filtered logging

Example

# Auto scale a deployment "foo", with the number of pods between 2 to 10, no target CPU utilization specfied 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 to 5, target CPU utilization at 80%:
kubectl autoscale rc foo --max=5 --cpu-percent=80
