I would like to deploy my rails app, which locally runs with foreman to a server, where supervisord handles the restarts.
Unfortunatley the app throws this error and I have no idea where $PORT comes from, nor from where this part gets started. Locally everything runs nice.
My app uses redis (which is the second part in the procfile) and puma as a webserver
