Heroku Gunicorn Procfile

python heroku flask gunicorn

Gunicorn takes a flag, --chdir, that lets you select which directory your Python app lives in. So, if you have a directory structure like:

my-project/  Procfile  my_folder/    my_module.py

and my_module.py contains:

app = Flask(__name__, ...)

You can put the following in your Procfile:

web: gunicorn --chdir my_folder my_module:app
