The Goal

Set up Kubernetes on 3 Debian Jessie virtual machines: One master. Two nodes. Additionally do this without any "magic" so that what is required to be running to make everything work is plain and obvious.

We will be using flannel for the inter-machine networking layer. Mainly because it is useful and it seems to be pretty popular.
