Building a Gitlab CI light using Elixir/Nerves - Hardware

Sun, 31 Mar 2019 22:24:30 +0000

It’s no secret I am a fan of Gitlab and I thought about ways to utilize their API/callbacks to create a fun project using Elixir/Nerves. Other companies have created their own versions of light based notifications, here’s my take on it.

Hardware

I am going to use a 3 color tower light from Adafruit to provide the visual aspect of the notification system. It will be controlled by a Raspberry PI Zero W or a Raspberry PI 3, the code can be shared between the two devices. A 4 channel 5v relay board will control turning the lights on and off via the GPIO. Power to the lamp requires the use of a barrel jack and a 12v power adapter.

Gitlab is a great development tool, getting better with every release. They give you access to their new-ish pipelining features on Gitlab.com for free. However, I wanted to setup the Gitlab Runner (this is what executes your CI build) on my own VPS using Docker. Gitlab makes this very easy to install, but the documentation is spread out when it comes to setup and execution. I thought an all in one document showing all the steps would be helpful to the community.
