// Out of the box, just by Using a .groovy file, you get probably something like (not tested):
client replicationControllers() inNameSpace "test" withName "nginx" rolling() image "nginx:1.9.3"

// With some simple wrapping of the default API you could get to:
client replicationControllers inNameSpace "test" withName "nginx" rolling image "nginx:1.9.3"

// You can probably do something fancy like this:
client replicationControllers where {
  nameSpace = "test"
  name = "nginx"
} rolling image "nginx:1.9.3"

// This last form might not be very easy to "guess" but I just wanted to show there are possibilities.
