Metacontroller is actually quite easy to learn. It comes with good examples too. Including a re-implementation of the Stateful Set controller, all done with iterations of an otherwise pure computation. The trick is obviously that the state lives in the k8s api server, from which the inputs of the subsequent invocation of your pure function come.
