corekube

It's pretty complicated with GCE itself. for GCE, I followed this http://kubernetes.io/v1.0/docs/getting-started-guides/gce.ht... guide. I eventually wanted to set it up in Rackspace where my company cloud lives. I used corekube(https://github.com/metral/corekube) heat templates to set it up but the way to add more minions to the cluster wasn't simple. On top of that there's this complicated networking I have to setup on rackspace, because k8s runs in its own flannel subnet which is actually overlayed on top of an isolated rackspace private subnet. To access the API externally I had to do some NAT manipulation to interface that private subnet to the rackspace public IP just to get the guestbook example working. Dunno how I'd have managed that with a more complex setup of multiple services.

It's great to see more options out there for folks to start playing with Kubernetes. It can be a bit daunting initially, especially for newcomers. As an alternative, I started a project called "Corekube" (https://github.com/metral/corekube) that allows you to kick the tires on Kubernetes on top of CoreOS. Corekube is an OpenStack based Heat template that just requires an OpenStack provider to stand up a Kubernetes cluster in minutes - the cluster comes complete with a private Etcd discovery service, 1 K8s master, 3 K8s minions, and a logic coordinator/deployment operator aka "the Overlord" which interacts with Etcd, Fleet and K8s via their API's to set things up.
