If you are using a released version of Kubernetes, you should refer to the docs that go with that version.
The latest release of this document can be found [here](http://releases.k8s.io/release-1.1/docs/user-guide/kubectl/kubectl_scale.md).Documentation for other releases can be found at releases.k8s.io.
Set a new size for a Replication Controller, Job, or Deployment.
Set a new size for a Replication Controller, Job, or Deployment.
Scale also allows users to specify one or more preconditions for the scale action. If --current-replicas or --resource-version is specified, it is validated before the scale is attempted, and it is guaranteed that the precondition holds true when the scale is sent to the server.
kubectl scale [--resource-version=version] [--current-replicas=count] --replicas=COUNT (-f FILENAME | TYPE NAME)
# Scale replication controller named 'foo' to 3.
$ kubectl scale --replicas=3 rc/foo
# Scale a resource identified by type and name specified in "foo.yaml" to 3.
$ kubectl scale --replicas=3 -f foo.yaml
# If the deployment named mysql's current size is 2, scale mysql to 3.
$ kubectl scale --current-replicas=2 --replicas=3 deployment/mysql
# Scale multiple replication controllers.
$ kubectl scale --replicas=5 rc/foo rc/bar rc/baz
# Scale job named 'cron' to 3.
$ kubectl scale --replicas=3 job/cron
--current-replicas=-1: Precondition for current size. Requires that the current size of the resource match this value in order to scale.
-f, --filename=[]: Filename, directory, or URL to a file identifying the resource to set a new size
-o, --output="": Output mode. Use "-o name" for shorter output (resource/name).
--replicas=-1: The new desired number of replicas. Required.
--resource-version="": Precondition for resource version. Requires that the current resource version match this value in order to scale.
--timeout=0: The length of time to wait before giving up on a scale operation, zero means don't wait.
--alsologtostderr[=false]: log to standard error as well as files
--api-version="": The API version to use when talking to the server
--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
