   === Install Kubernetes Node
   
   The Kubernetes node only run the kubernetes proxy and the pods. 
  
positive.code: 
  == 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. 
  
  
  == Add Swap (optional)
  
negative.code: WantedBy=multi-user.target
  ....
  
  Set _export KUBERNETES_MASTER=http://rpi-master:8080_ so your _kubectl_ can connect the kubernetes REST API on the master. Now  verify your nodes are registered
  ....
  kubectl get nodes
  NAME         LABELS                              STATUS
  rpi-master   kubernetes.io/hostname=rpi-master   Ready
  rpi-node-1   kubernetes.io/hostname=rpi-node-1   Ready
  rpi-node-2   kubernetes.io/hostname=rpi-node-2   Ready
  rpi-node-3   kubernetes.io/hostname=rpi-node-3   Ready
  ....
  
  Yay it worked!
  
  === Open Docker for remote connections.
  
  Finally we need to fix up the Docker configuration so it accepts remote connections, so we can deploy something to it. Open the _/etc/default/docker_ file for editing and set the DOCKER_OPTS
  ....
  	DOCKER_OPTS="-H tcp://192.168.1.9:2375 -H unix:///var/run/docker.sock --storage-driver=overlay -D"
  ....
  where the IP address of machine, or you can user '0.0.0.0' to bind to all interfaces. Now we can remotely push docker images to the master. In my next post I'm going to deploy a fabric8, note that the docker images you want to run need to be based on an ARM architecture or else they won't run!
