What's a Procfile 👀

Posted on 1 Jul, 2019

I recently deployed a Python application on Heroku, there I encountered a Procfile. This is what I got to know :

  • The Procfile is a simple text file that is named Procfile without a file extension. For example, Procfile.txt is not a valid Procfile.

  • It specifies the commands that are executed by the app on startup. For e.g A Django server.

  • Example: If you want to run a python script on Heroku, your Procfile content should be worker: python script.py
