Quick notes on the Nerves setup steps to enable an mcp2515 can controller on an rpi3

can0 setup

(for mcp2515 controller like the PiCAN2)

  1. fork (or clone) nerves_system_rpi3 locally into the parent directory of your project

  2. edit mix.exs and change the nerves_system_rpi3 lines to point to your local one:

     def system("rpi3"), do: [{:nerves_system_rpi3, path: "../nerves_system_rpi3", runtime: false}]

  3. mix deps.get

  4. mkdir config/rpi3 to set up a place to store some customized rpi configs

Deploying Elixir and Phoenix applications using Docker and Exrm

Goal

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.

Assumptions

  1. You already have a working Elixir environment with the Phoenix Framework installed
  2. You have at least basic working knowledge of Docker, and have installed the Docker tools onto your local environment
