## 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 RESOURCE ID
```

### Examples

```
// 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
```

### Options

```
      --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.
```
