Setup for this lab

Expected Outcome

Three hosts that can talk to each other over ports 2379 and 2380. This document assumes these default ports. However, they are configurable through the kubeadm config file.
Each host must have docker, kubelet, and kubeadm installed.
- In our case, we will be using RancherOS which have docker installed.
- We will manually install kubelet and kubeadm.
Some infrastructure to copy files between hosts. For example ssh and scp can satisfy this requirement.
