How do I run a flask app in gunicorn if I used the application factory pattern?
Create a file wsgi.py under your project with the following contents, then point Gunicorn at it.
from my_project import create_appapp = create_app()gunicorn -w 4 my_project.wsgi:app# -w 4 specifies four worker processesIf you're using the application factory pattern, Gunicorn allows specifying a function call like my_project:create_app(). For most cases, you can the skip making a wsgi.py file and tell Gunicorn how to create your app directly.
gunicorn -w 4 "my_project:create_app()"Note that the quotes are necessary in some shells where parentheses have special meaning.
You need to create_app() with specific factory config in run.py. See the code below:
from your_app import create_appif __name__ == "__main__": app = create_app(os.getenv('FLASK_CONFIG') or 'dev') app.run()And then, you could run command gunicorn -w 4 -b 0.0.0.0:5000 run:create_app('dev') to run the application.
