You should check out Rancher - they fully automate/orchestrate the installation of Kubernetes (along with Mesos, Swarm, or Cattle) and support some advanced features like blue/green deployments by integrating with the Kubernetes ingress feature: http://rancher.com/rancher-controller-for-the-kubernetes-ing...
Rancher Labs definitely seems to be further along the path of a production-ready container hosting platform than any other one I've tried so far.
I'm surprised I don't read more about Rancher qurg everyone focusing on k8s.
Not only can Rancher use k8s for scheduling, but mixing and matching environments with different scheduling technologies is extremely powerful instead of pigeon holing yourself on a one-size-fits all approach for you applications.
