I have been trying to deploy my flask app on aws using their elastic beanstalk service but I havnt had any luck. I have tried renaming app to application or import as application. I have tried adding different things to httpf.conf. But, no luck.

Any ideas?

Here is some examples of what i am using/running into.

This is because somewhere in your code you are starting the builtin Flask developer server. This is evident from the message:

Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Usually this is because app.run() is being called, but that is not evident in what you have shown.

Either way, you shouldn't be starting up the Flask development server as mod_wsgi under Apache is acting as the WSGI server.

  • it was these lines that did it... app.config["APP_SETTINGS"] = "northtrack.config.DevConfig" app.config.from_object(app.config["APP_SETTINGS"]). Thanks! – Adnan Dossaji Nov 29 '16 at 05:33

    Those lines shouldn't start the builtin developer server which was problem I was highlighting. Maybe you hadn't restarted Apache after some prior change where you removed what was causing it. – Graham Dumpleton Nov 29 '16 at 05:41
  • You are correct. I added those lines in after restarting apache and it worked. It was app.run() that was doing it but i never restarted Apache. Thanks again! – Adnan Dossaji Nov 29 '16 at 05:50
  • just put app.run under... if __name__ == "__main__": – Adi Jan 22 '17 at 22:35
