This snippet shows how to run simple continuously running python scripts on Heroku

python_on_heroku.md

Deploying long running python scripts on Heroku

1. Add Procfile with the following contents

worker: python your_script.py

2. Add requirements.txt file with the format MODULE_NAME==MODULE_VERSION. Example:

slackclient==1.2.1

Note: Don't add all the requirements using pip freeze as this may create a huge file with so many requirements including conda if you use one, instead pick the ones that are absolutely required

3. Push code to heroku and it should be successfully deployed
4. Now we need to run the infinitely listening script on a worker instance

heroku ps:scale worker=1

5. Check Heroku logs to see outputs such as Listening on ... using

heroku logs --tail
