Welcome from Linux Developer & User

This repository was commissioned to support a tutorial published in Issue 163 of Linux User and Developer Magazine.

In the article I outline the case for Docker Swarm on the Raspberry PI and..

  • Install and configure Arch Linux giving a static IP address

  • Go into detail on how to recompile the latest version of Docker from an older (issue-free) version

Updates for Step 7 & 8

Please skip both of these steps and run the below instead (this is because Docker 1.10-3 is fully working in the package repository)

07 Install Docker 1.7.1 08 Build Docker on Docker!

# pacman -Sy docker
# sudo systemctl enable docker
# sudo usermod lud -aG docker
# sudo reboot

Edit /usr/lib/systemd/system/docker.service and add the following to the line starting ExecStart to:

ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://0.0.0.0:2375 --cluster-advertise eth0:2375 --cluster-store consul://192.168.0.35:8500

  • We then build Docker Swarm itself

  • Build out native images for Node.js, Redis and Consul.

Finally we put it all together and use Apache-Bench to load-test the solution with Nginx doing load-balancing for us.

I have provided a much condensed and abbreviated version of the steps in this guide: Follow the condensed guide
