Get Docker up and running on the RaspberryPi (ARMv6) in three steps
This tutorial describes useful things if you want to set up and run Docker on your RaspberryPi from scratch. If you prefer a ready to use image you may want to read this article and take the image provided by the Hypriot team. As always some people feel better if they can do the set up by themselves and don't need to trust other people's images. If you belong to this particular group you may want to continue reading.
You will need a Raspberry Pi running Raspbian. I've taken the stand alone Jessie image (and not NOOBS), since I wanted to use the Raspberry Pi headless.
The official Raspbian comes with a lot of packages pre-installed, many of them don't make sense if you want to run the Raspberry Pi as a server (e.g. without a display attached). So I've decided to delete packages I'm not going to miss very much (thanks to cnxsoft).

The Hypriot team has made a great job, automating the process of building a raspbian wheezy package for Docker, with Docker on ARM. Any docker enabled ARMv7 device will work as well. If you don't have any, you may take a look at Scaleway, they offer AWS like services based on ARMv7:
$ git clone https://github.com/hypriot/rpi-docker-builder.git
$ cd rpi-docker-builder
$ sudo sh build.sh
$ sudo sh run-builder.sh
You will find the docker install package in ./dist/docker-hypriot_1.8.1-1_armhf.deb .
The Hypriot team offers the installation package for download now, you don't need to create the installation package by yourself.
$ curl -sSL http://downloads.hypriot.com/docker-hypriot_1.8.2-1_armhf.deb >/tmp/docker-hypriot_1.8.2-1_armhf.deb
$ sudo dpkg -i /tmp/docker-hypriot_1.8.2-1_armhf.deb
$ rm -f /tmp/docker-hypriot_1.8.2-1_armhf.deb
$ sudo sh -c 'usermod -aG docker $SUDO_USER'
$ sudo systemctl enable docker.service
See if it works:
