What:

Docker image based on centos:latest which builds Kubernetes from scratch upon start and moves binaries to /target.

Why:

I need an easy way to install Kubernetes on CoreOS.

Usage:

Whenever the container is run, it builds the latest Kubernetes binaries and moves them to the /target volume (any existing binaries will get overwritten).

So, to install or update Kubernetes, i.e. within /opt/kubernetes, just run

docker run --rm -v /opt/kubernetes:/target digitalwonderland/kubernetes

To build a specific branch just pass its name as parameter. If none is passed the master branch gets build.
