Python Flask on IIS: WARNING: This is a development server. Do not use it in a production deployment-CodePudding

We followed this guide on setting up Flask on IIS https://medium.com/@dpralay07/deploy-a-python-flask-application-in-iis-server-and-run-on-machine-ip-address-ddb81df8edf3 and it works well but when we do flask run from VS code we get the following

PS J:\Apps\prod> flask run
 * Serving Flask app 'wsgi.py' (lazy loading)
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000 (Press CTRL C to quit)

About the development server line and the production WSGI server line - is this purely because we set it up in IIS? Should we have followed a different route than what was in that guide we followed?

Everything else I'm seeing seems to be only relevant to *nix based systems i.e using Gunicorn

Thanks

I see you are working in a development environment. Run the following code to set you environment to development mode to remove the warning:

export FLASK_APP=your-flask-app-name
export FLASK_ENV=development
flask run

This warning means that you are using the standard flask server. Of course, it should not be used in production. You need to use some kind of wsgi-server like gunicorn, uwsgi, waitress etc. Check out the deployment documentation so you can properly deploy your Flask application. Well, and to remove the inscription;)
