name: scale
|
|
synopsis: |
|
|
Set a new size for a Deployment, ReplicaSet, Replication Controller, or Job.
|
|
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:
|
|
- name: current-replicas
|
|
default_value: "-1"
|
|
usage: |

|
Precondition for current size. Requires that the current size of the resource match this value in order to scale.
