Docker on my Raspberry PI Cluster

Installation

See here https://docs.docker.com/engine/installation/linux/debian/

Purge any older repositories (not necessary with a clean, new debian installation)

$ apt-get purge "lxc-docker*"
$ apt-get purge "docker.io*"

Update package information, ensure that APT works with the https method, and that CA certificates are installed.

$ apt-get update
$ apt-get install apt-transport-https ca-certificates gnupg2

Add the new GPG key.

$ sudo apt-key adv \
       --keyserver hkp://ha.pool.sks-keyservers.net:80 \
       --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

Edit /etc/apt/sources.list.d/docker.list

deb https://apt.dockerproject.org/repo debian-jessie main

Verify that APT is pulling from the right repository.

$ apt-cache policy docker-engine

Hello from Docker on armhf!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
