## kubectl rolling-update

Perform a rolling update of the given ReplicationController.

### Synopsis


Perform a rolling update of the given ReplicationController.

Replaces the specified replication controller with a new replication controller by updating one pod at a time to use the
new PodTemplate. The new-controller.json must specify the same namespace as the
existing replication controller and overwrite at least one (common) label in its replicaSelector.

```
kubectl rolling-update OLD_CONTROLLER_NAME ([NEW_CONTROLLER_NAME] --image=NEW_CONTAINER_IMAGE | -f NEW_CONTROLLER_SPEC)
```

### Examples

```
// Update pods of frontend-v1 using new replication controller data in frontend-v2.json.
$ kubectl rolling-update frontend-v1 -f frontend-v2.json

// Update pods of frontend-v1 using JSON data passed into stdin.
$ cat frontend-v2.json | kubectl rolling-update frontend-v1 -f -

// Update the pods of frontend-v1 to frontend-v2 by just changing the image, and switching the
// name of the replication controller.
$ kubectl rolling-update frontend-v1 frontend-v2 --image=image:v2

// Update the pods of frontend by just changing the image, and keeping the old name
$ kubectl rolling-update frontend --image=image:v2

```

### Options

```
      --deployment-label-key="deployment": The key to use to differentiate between two different controllers, default 'deployment'.  Only relevant when --image is specified, ignored otherwise
      --dry-run=false: If true, print out the changes that would be made, but don't actually make them.
  -f, --filename="": Filename or URL to file to use to create the new replication controller.
  -h, --help=false: help for rolling-update
      --image="": Image to use for upgrading the replication controller.  Can not be used with --filename/-f
      --no-headers=false: When using the default output, don't print headers.
  -o, --output="": Output format. One of: json|yaml|template|templatefile|wide.
      --output-version="": Output the formatted object with the given version (default api-version).
      --poll-interval="3s": Time delay between polling for replication controller status after the update. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
      --rollback=false: If true, this is a request to abort an existing rollout that is partially rolled out. It effectively reverses current and next and runs a rollout
  -t, --template="": Template string or path to template file to use when -o=template or -o=templatefile.  The template format is golang templates [http://golang.org/pkg/text/template/#pkg-overview]
      --timeout="5m0s": Max time to wait for a replication controller to update before giving up. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
      --update-period="1m0s": Time to wait between updating pods. Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".
