## kubectl scale Set a new size for a Replication Controller, Job, or Deployment. ### Synopsis 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) ``` ### Examples ``` # 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 ``` ### Options ``` --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). --record[=false]: Record current kubectl command in the resource annotation. --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. ``` ### Options inherited from parent commands ``` --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 ``` ### SEE ALSO * [kubectl](kubectl.md) - kubectl controls the Kubernetes cluster manager ###### Auto generated by spf13/cobra on 29-Feb-2016 []()
