So when do they throw their Microsoft wrench in it..

"Oh and these Kubernetes features only work on Azure Cloud(tm) running Windows Server(tm), or Microsoft Linux(tm)."

I don't know.. does anyone that isn't a .net shop use Azure? It seems if you are a .net shop, Azure is the best choice. If you are not a .net shop, why use Azure? If Microsoft is going to reach a compelling chunk of AWS and GCE linux developers, I don't think they are going have that easy of a time...
