I have recently posted a few questions on GKE/Kubernetes deployment issues to ServerFault and StackOverflow. [A first one][1] has been downvoted and voted-to-close, presumably because it was not strictly about programming, although StackOverflow apparently hosts many other questions on GKE/Kubernetes operational issues as well. (I have later cross-posted/migrated [the same][2] question to ServerFault.)

So here is my meta question: What is the best/better place for asking  questions about GKE/Kubernetes deployment (etc.) in terms of site rules and size of expert audience? There seem to be more such questions/answers present on StackOverflow. I have received more answers on ServerFault so far. Or is best way forward to open GKE-Kubernetes-related questions as [issues][3] on GitHub as many seem to do? Has there been any "official" communication e.g. from Google on this matter?
