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

# How to use it:
#
# Plug it at the end of your :browser pipeline in your Phoenix app router.ex
# Make sure it is plugged before your session-based authentication and authorization Plugs.
#
# pipeline :browser do
#   plug :accepts, ["html"]
#   plug :fetch_session
#   plug :fetch_flash
#   plug :put_secure_browser_headers
