In my experience, Erlang doesn't have a standard way of doing a deployment. There are 3rd party apps like Rebar and others, but they are both not available by default (after a fresh install) and seriously underdocumented. The result of this, IMHO, is that everyone builds their own build and deployment system, using shell scripting, Make or Erlang itself.

Elixir includes Mix - a standard task runner - and Hex as part of the distribution. It also provides a central pkg repository (https://hex.pm/packages). It's much, much easier to start a project and pull all your dependencies.

I guess you could use Hex and Mix with pure Erlang projects, but I haven't tried this.
