OpenShift Error The requested URL / was not found on this server

Question

I've been trying to deploy a flask app on openshift. I tested the website and it runs just fine on the development server (both by typing python app.py and manage.py runserver), I uploaded the project to github and created the app using this command from terminal:

rhc create-app marcsantiago python-2.7 --from-code=https://github.com/marcsantiago/personalwebsite.git

The app seems to be created without a problem. The issue occurs when I try and visit the created url:

http://marcsantiago-mywebappsflask.rhcloud.com

I receive a not found error The requested URL / was not found on this server.

I don't understand what i did wrong or how to fix it so that the website it live. It is a simple website, which uses no databases.

Could someone please help me resolve this issue?

this the postgresql.log information, though i'm not sure how relevant it is since i don't use a database, python.log is below

sorry for how messy it looks, couldn't think of a better way to share the logs other than pasting them in.

Answer 1

Have you tried reading through the section of the Developer Portal that is about using Flask on OpenShift Online?

https://developers.openshift.com/en/python-flask.html

Answer 2

The domain is not pointing to any server.

This is most likely an issue in your configuration on Openshift, an error in their server configuration or a mistyping of the URL on your side.

Contact Openshift or check their logs.

Edit: Looking at the new logs, it becomes clear that the server can't find your WSGI app. You mention that it is called app.py, but the server may be looking for something else. The more common file name would be application.py. Check your configuration at OpenShift and adjust the WSGI application file name accordingly.
