Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

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

# two different ways to implement a find_or_create for Ecto

find_or_create_user = fn user ->
  case Repo.all(from u in users, where: u.id == ^user.id and u.email == ^user.email) do
    [] ->
      %User{}
      |> User.changeset(user)
      |> Repo.insert!()
    _ ->
      IO.puts "Already inserted"
