Tutorial: docker-on-arm

I am using Armbian for my head-less servers. Currently this setup is running on a Raspberry Pi 1, a Raspberry Pi 2 and a Olimex A20-OLinuXino-LIME.

Installation is quite simple.

  1. Install dependencies

    apt-get install -y apt-transport-https
  2. Add respository key

    wget -q https://packagecloud.io/gpg.key -O - | sudo apt-key add -
  3. Add repository

    echo 'deb https://packagecloud.io/Hypriot/Schatzkiste/debian/ jessie main' | sudo tee /etc/apt/sources.list.d/hypriot.list
    apt-get update
  4. Install Hypriot

    apt-get install -y docker-hypriot
    systemctl enable docker

Afterwards docker is ready to use.

You can test your docker installation:

Keep in mind that only ARM-based containers will run on ARM devices. You can search for valid containers with tags like “armhf” or “hypriot”:
