I just wrote a controller that does pretty much that – spawn containers on demand and report back status changes. While this solution does require some knowledge, it so far has been perfectly reliable and reasonably fast. I can fathom the need for processes to spawn and tear down faster in specific use cases than the Kubernetes scheduler would allow for, but for us a few seconds of wait time has been perfectly reasonable.
