OpsCaptain can deploy Elixir and Phoenix applications using the heroku-buildpack-elixir and heroku-buildpack-phoenix-static. From the developers perspective, you simply deploy your code using the CLI and OpsCaptain configures the environment to compile your application using the buildpacks. If you are interested in customizing runtime parameters such as the version of erlang, elixir, node.js to be used to compile your application.
