Set a new size for a Replication Controller.
Set a new size for a Replication Controller.
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 RESOURCE ID
// Scale replication controller named 'foo' to 3.
$ kubectl scale --replicas=3 replicationcontrollers foo
// If the replication controller named foo's current size is 2, scale foo to 3.
$ kubectl scale --current-replicas=2 --replicas=3 replicationcontrollers foo
--current-replicas=-1: Precondition for current size. Requires that the current size of the replication controller match this value in order to scale.
-h, --help=false: help for scale
--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.
--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 key 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
--validate=false: If true, use a schema to validate the input before sending it
--vmodule=: comma-separated list of pattern=N settings for file-filtered logging
