OpenStack and Kubernetes Get the Heat Treatment

Take advantage of autoscaling, and high availability for Kubernetes with no worry about infrastructure. Be the Rockstar and avoid all the hurdles of deploying Kubernetes. So Why not take Heat and automate the setup of your Kubernetes cluster? Why not give project owners a Heat Stack to deploy Kubernetes whenever they want to?

Hoping to share how anyone can use Heat to deploy Kubernetes on OpenStack and customize to their liking. 

This is a tried and true method that I've used on my OpenStack clusters and I will share the benefits, bumps along the way and the lessons learned.

These Heat templates will deploy a cluster of Nova instances running Kubernetes from the Kubic project. 

The cluster uses Flannel to provide an overlay network connecting pods deployed on different nodes. You can determine the initial size of the cluster via a configuration parameter when you deploy it, and the cluster will scale dynamically (up to a specified maximum size) due to CPU load on the Kubernetes nodes.
