Configure Heroku app with only scheduled jobs?

Question

I want to spin up a Heroku instance that only runs a few jobs scheduled with the Heroku Scheduler add-on. I don't want any processes to start on deploy. Should I configure a dummy process, add an empty Procfile, omit the Procfile, or something else?

Answer 1

An empty Procfile works. Still need to try omitting the Procfile.
