My gunicorn command ( i run this in my dockerfile )- CMD gunicorn -b 0.0.0.0:9000 --worker-class eventlet --access-logfile - "my.app:create_app()"

My requirements.txt eventlet==0.17.4 flask-socketio greenlet==0.4.2

I’m not able to figure out why its not working when i integrate this into my app. When i run this separately it works. Please help!
