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.

Creating Keys

This is a brief guide to creating a public/private key pair that can be used for OpenSSL. While the "easy" version will work, I find it convenient to generate a single PEM bundle and then export the private/public key from that as needed. This document also covers how to add and remove a password from your private key and how to make sure that keychain will automatically unlock it when you sign in.

Just make it work

Generate an ssh key-pair:

openssl rsa -in ~/.ssh/id_rsa -outform pem > id_rsa.pem
chmod 700 id_rsa.pem

// BrowserRouter is the router implementation for HTML5 browsers (vs Native).
// Link is your replacement for anchor tags.
// Route is the conditionally shown component based on matching a path to a URL.
// Switch returns only the first matching route rather than all matching routes.
import {
  BrowserRouter as Router,
  Link,
  Route,
  Switch,
