## kubectl scale
|
||||
|
||||
Set a new size for a Replication Controller.
|
||||
|
||||
### Synopsis
|
||||
|
||||
|
||||
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.
|
||||
|
||||
```
|
||||
{% raw %}
|
||||
kubectl scale [--resource-version=version] [--current-replicas=count] --replicas=COUNT (-f FILENAME | TYPE NAME)
|
||||
{% endraw %}
|
||||
```
|
||||
|
||||
### Examples
|
||||
|
||||
```
|
||||
{% raw %}
|
||||
# Scale replication controller named 'foo' to 3.
|
||||
$ kubectl scale --replicas=3 replicationcontrollers foo
|
||||
|
||||
# Scale a replication controller identified by type and name specified in "foo-controller.yaml" to 3.
|
||||
$ kubectl scale --replicas=3 -f foo-controller.yaml
|
||||
|
||||
# If the replication controller named foo's current size is 2, scale foo to 3.
|
||||
$ kubectl scale --current-replicas=2 --replicas=3 replicationcontrollers foo
|
||||
|
||||
# Scale multiple replication controllers.
|
||||
$ kubectl scale --replicas=5 rc/foo rc/bar
|
||||
{% endraw %}
|
||||
```
|
||||
|
||||
### Options
|
||||
|
||||
```
|
||||
{% raw %}
|
||||
--current-replicas=-1: Precondition for current size. Requires that the current size of the replication controller match this value in order to scale.
|
||||
-f, --filename=[]: Filename, directory, or URL to a file identifying the replication controller to set a new size
|
||||
-o, --output="": Output mode. Use "-o name" for shorter output (resource/name).
|
||||
--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.
|
||||
{% endraw %}
|
||||
```
|
||||
|
||||

|
||||
