Since that post went live, I’ve done experimentation on my own, and also learned a few things about the deployment toolset being used for the Kubernetes Cluster Template.

Azure Stack Kubernetes Cluster is NOT AKS

If you’ve been test driving Azure Stack with a full stamp or just the ASDK, you may have decided to try out the Kubernetes Cluster template that is available in the marketplace syndication. This post is meant to walk through what the K8s template is, what it isn’t, and how it works.
