Using Elixir releases and multi-stage Docker files to simplify Phoenix deployment

This repo is my experiment in deploying a basic Phoenix app using the release feature from elixir 1.9 (https://elixir-lang.org/blog/2019/06/24/elixir-v1-9-0-released/) and docker, via a multi-stage Dockerfile (https://docs.docker.com/develop/develop-images/multistage-build/) leveraging bitwalker's docker images for Elixir and Phoenix.

Step 1: Install Elixir 1.9.1 (and Erlang)

The simplest way to manage Elixir versions is to use asdf.

mysql2 install failing on Mac OS X (Mojave)

If you want to install the gem (client) without having a database, doing brew install mysql-connector-c used to work, but not anymore.

You now have to install a compatible connector (mariadb):

brew install mariadb-connector-c
bundle config build.mysql2 "--with-mysql-config=$(brew info mariadb-connector-c | grep /usr/local | cut -d ' ' -f 1)/bin/mariadb_config"
bundle install
