## 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.

```
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 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
```

### Options

```
      --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.
```

### Options inherited from parent commands

```
      --alsologtostderr[=false]: log to standard error as well as files

      --user="": The name of the kubeconfig user to use
      --username="": Username for basic authentication to the API server.
