Usage:
```
kubectl version [flags]
Available Flags:

#### rollingupdate
Perform a rolling update of the given ReplicationController.
Replaces named controller with new controller, updating one pod at a time to use the
new PodTemplate. The new-controller.json must specify the same namespace as the
existing controller and overwrite at least one (common) label in its replicaSelector.

$ kubectl rollingupdate frontend-v1 -f frontend-v2.json
<update pods of frontend-v1 using new controller data in frontend-v2.json>
$ cat frontend-v2.json | kubectl rollingupdate frontend-v1 -f -
