Easy Kubernetes Installation on CoreOS

At Timeline Labs, we are continuously looking at new technologies to see what fits our needs. We are especially excited about Kubernetes from Google to manage our services atop Docker and CoreOS.

This process for installing Kubernetes on CoreOS uses Flannel for Kubernetes networking and should be cloud provider agnostic. To deploy the Kubernetes master functionality into the cluster, it uses fleetctl.

Thanks to Kelsey Hightower and his blog posts! They served as a great starting point for this process.

How do I get this running?

Add the cloud config below to your own and bring up your cluster using a CoreOS version with Docker 1.3 (currently v472.0.0 in alpha). During that initial boot, the download-kubernetes and download-flannel units will download binaries from the latest project release and use those.
