Heroku: Running multiple python processes in a single dyno using Honcho

Tue, 04/09/2013 - 20:41 | dasty

Recently I had exactly the same problem as Jonatan Heyman in his post Heroku: Running multiple python processes in a single dyno using foreman. I also needed to run a web and Celery process in one Heroku dyno during prototyping.

I really liked Jonatan's approach, but as the $PORT bug was fixed recently, I decided to use Honcho in order to avoid mixing ruby and python in one project.

The process is quite straight forward:

Install Honcho using "pip install honcho".
Regenerate your requirements.txt to include Honcho.
Rename your current Procfile to ProcfileHoncho.
Create a new Procfile with the following content
```
web: honcho -f ProcfileHoncho start
```

That should theoretically be it. Unfortunately, there is a small bug in Honcho. Before this bug gets fixed you will need to run the following workaround for Honcho to work properly:

heroku config:set USER=heroku

Awesome tutorial!

I also have a small django side project (I wanted to run both the web front-end and celery on a singly dyno while I was still prototyping).

This worked awesome for me, the bug fix was in the latest version (I got 0.6.6) and everything worked (running django 1.7, python3, and celery 3.1).

Thanks!
