Setting custom process as Heroku web process type

96 views Asked by Sergio Tapia At 05 September 2017 at 19:36

I have a git repository with two applications. One backend API, the other client-side application.

In my root Procfile, I have this:

api: cd apps/api && mix phx.server
clientside: cd apps/clientside && mix phx.server

However Heroku complains that there is no web process type.

heroku[router]: at=error code=H14 desc="No web processes running"

How can I tell Heroku to use a custom process in my procfile as the web process?
