SYNOPSIS

kubectl scale [OPTIONS]

DESCRIPTION

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.

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.
