Docker on a Raspberry Pi
Raw
README.md
  • Get a Raspberry
  • Install Archlinux on it, see http://archlinuxarm.org/platforms/armv6/raspberry-pi
  • Get latest package info: pacman -Sy
  • install sudo pacman -S sudo
  • create a user in group wheel useradd -m -G wheel -s /bin/bash pixelistik
  • in /etc/sudoers allow everything to wheel group visudo, uncomment the %wheel line
  • mkdir .ssh
  • chmod 755 .ssh/
  • nano .ssh/authorized_keys and paste public key
  • chmod 644 .ssh/authorized_keys
  • pacman -S docker
  • add user to docker group to get permissions to run docker commands usermod -aG docker pixelistik
  • start docker daemon sysctl start docker (sysctl enable docker probably makes it persistent)
  • get a base image that matches the host docker pull sdhibit/rpi-arch (could probably be any other ARM-based Linux, e.g. Raspbian)
  • write a Dockerfile
  • build the docker image, saving it under a tag docker build -t estimation-poker .
  • run the image, publishing port 5000: docker run -p 5000:5000 estimation-poker
