Starting from a Unbuntu server with Nginx installed and set up with Let’s Encrypt HTTPS, we install Postgres, Elixir and Phoenix and then make an automated deployment system using Distillery and Edeliver.

After setting everything up, deployment can be done entirely from your local machine and upgrades take only only a single command.
