  +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!

  === 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_).
