   == Power up and add DNS
   
  -You can now power up the first Pi. By default to login use root/hypriot. You will need to set up DNS for each of the Pi's. If you don't want to hook up a monitor and keyboard to login at the console to figure out its IP and Mac address, then you can use nmap [3] to figure this out. If you have a DNS service provision it there, or else name the Pi's in /etc/hosts. I named my Pi's _rpi-master_, _rpi-node-1_, _rpi-node-2_ and _rpi-node-3_. With a quick reboot of each Pi you will see the names reflected at the cmd prompt. Note that if you skip the DNS step your Kubernetes cluster will not work.

I added the following to my _/etc/hosts_ files on all machines

  +192.168.1.9     rpi-master
  +192.168.1.21    rpi-node-1
  +192.168.1.18    rpi-node-2

   == Add Swap (optional)
  
positive.code:     ./build-master.sh

  === Install Kubernetes Node
  
  The Kubernetes node only run the kubernetes proxy and the pods. 
  
negative.code:     ./build-worker.sh
  ....
  
  Finally you need to point the node to its master. Edit the _/etc/systemd/system/kubelet.service_ file and add the master's Kubernetes REST endpoint to the 'api-servers' (which in my case is _http://192.168.1.9:8080_).
