kubectl scale

kubectl scale

Set a new size for a Deployment, ReplicaSet, Replication Controller, or Job

Synopsis

Set a new size for a Deployment, ReplicaSet, Replication Controller, or Job.

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)

Examples

  # Scale a replicaset named 'foo' to 3.
  kubectl scale --replicas=3 rs/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

Options

      --current-replicas int      Precondition for current size. Requires that the current size of the resource match this value in order to scale. (default -1)
  -f, --filename stringSlice      Filename, directory, or URL to files identifying the resource to set a new size
  -o, --output string             Output mode. Use "-o name" for shorter output (resource/name).
      --record                    Record current kubectl command in the resource annotation. If set to false, do not record the command. If set to true, record the command. If not set, default to updating the existing annotation value only if one already exists.
  -R, --recursive                 Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.
      --replicas int              The new desired number of replicas. Required. (default -1)
      --resource-version string   Precondition for resource version. Requires that the current resource version match this value in order to scale.
      --timeout duration          The length of time to wait before giving up on a scale operation, zero means don't wait. Any other values should contain a corresponding time unit (e.g. 1s, 2m, 3h).

      --certificate-authority string     Path to a cert. file for the certificate authority
      --client-certificate string        Path to a client certificate file for TLS

      --context string                   The name of the kubeconfig context to use
      --insecure-skip-tls-verify         If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure
      --kubeconfig string                Path to the kubeconfig file to use for CLI requests.
      --log-backtrace-at traceLocation   when logging hits line file:N, emit a stack trace (default :0)
      --log-dir string                   If non-empty, write log files in this directory
      --logtostderr                      log to standard error instead of files
      --match-server-version             Require server version to match client version

      --request-timeout string           The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0")
  -s, --server string                    The address and port of the Kubernetes API server
