The new-controller.json must specify the same namespace as the existing controller and overwrite at least one (common) label in its replicaSelector. Examples: $ 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 - <update pods of frontend-v1 using json data passed into stdin> Usage: ``` kubectl rollingupdate <old-controller-name> -f <new-controller.json> [flags] Available Flags: --alsologtostderr=false: log to standard error as well as files --api-version="": The API version to use when talking to the server -a, --auth-path="": Path to the auth info file.

It's useful to see generated markdown of help output for the full command tree, e.g. if you want to link to the syntax on irc or something. Anyway, this was quite easy to do, I'll have a PR shortly.
