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.
