I use gunicorn --workers 3 wsgi to run my Flask app. If I change the variable application to myapp, Gunicorn gives the error AppImportError: Failed to find application: 'wsgi'. Why am I getting this error and how do I fix it?
myproject.py:
from flask import Flask myapp = Flask(__name__) @myapp.route("/") def hello(): return 'Test!' if __name__ == "__main__": myapp.run(host='0.0.0.0') wsgi.py:
from myproject import myapp if __name__ == "__main__": myapp.run() Gunicorn (and most WSGI servers) defaults to looking for the callable named application or app in whatever module you point it at. Simply adding an alias from myproject import myapp as application or application = myapp will let Gunicorn discover the callable again.
However, the wsgi.py file or the alias aren't needed, Gunicorn can be pointed directly at the real module and callable. There is almost never a good reason to have a separate wsgi.py file.
gunicorn myproject:myapp --workers 16 If you're trying to serve an app named app within server/app.py, you can start the server on port 8000 as follows:
gunicorn server.app:app -b 0.0.0.0:8000
