My app requires a custom start command.
the "collectstatic" is needed in prod to copy the contents from static to staticfiles.

Essentially, it needs to run:

python manage.py collectstatic --clear --no-input
python manage.py runserver
gunicorn my_project.wsgi:application

The issue is that runserver and gunicorn are both commands that need to run in the foreground; and I've already tried several combinations of trying to modify the start command, running in the background, etc.

1. Custom start command (doesn't like ";" to run multiple commands)

python manage.py collectstatic --clear --no-input && python manage.py runserver && gunicorn mu_project.wsgi:application

2. Wrapping these in a shell script, e.g,.

   /bin/sh -c "/app/run_prod.sh"

3. Running both the script and Gunicorn,

   /bin/sh -c "/app/run_prod.sh" && gunicorn stealth_ai.wsgi:application
