True. My only experience is with VMware OpenStack, and my quick googling didn't turn up much info. I think Kubernetes will fall to the same fate as OpenStack is sliding into. Growing complexity with promises of the world. Time will tell.

You seem to know more than I do, so I got to ask. Why does openstack-helm exist? Why would anyone want to deploy OpenStack on top of kubernetes? Is it so you can have the OpenStack API run in Kubernetes that manages physical boxes?
