 + 
 +An automated script maintained by the Docker project will create a systemd service file and copy the relevant Docker binaries into /usr/bin/. 
 + 
 +  sudo curl -sSL https://get.docker.com | sh 
 + 
 +Set Docker to auto-start: 
 + 
 +  sudo systemctl enable docker 
 + 
 +Or start Docker manually: 
 + 
 +  sudo systemctl start docker 
 + 
 +The Docker client can only be used by root or members of the docker group. Add pi or your equivalent user to the docker group: 
 + 
 +  sudo usermod -aG docker pi 
 + 
 +Test the Docker install by downloading and running Alpine Linux: 
 + 
 +  docker run -ti arm32v6/alpine:3.5 /bin/sh 
 + 
 +Note that Docker creates a new docker0 network interface. 
 + 
 +==== Kubernetes ==== 
 + 
 +[[https://blog.hypriot.com/post/setup-kubernetes-raspberry-pi-cluster/|Setup Kubernetes on a Raspberry Pi Cluster]] 
 + 
 +First, trust the kubernetes APT key and add the official APT Kubernetes repository on every node: 
 + 
 +  curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg > apt-key.gpg 
 +  sudo apt-key add apt-key.gpg 
 +  echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" > /etc/apt/sources.list.d/kubernetes.list

-Docker+  apt-get update 
 +  apt-get install -y kubeadm
