Running Flask Demos

Note: Visual Studio Code is configured to use /home/coder as the project home folder. Any new files and folders during development must be created under /home/coder .

Follow below steps to create and run the demos:

• Make sure to create new Flask projects inside the /home/coder/ directory, so that your new projects will be available in the Browser based Visual Studio Code.

• Once your project is created, navigate to your project directory where your app.py file exist.

  cd /home/coder/my_flask_app

• Then switch to the super user. This is required to run Flask server on port 80

  sudo su

• Then set the FLASK_APP environment variable to the app file

  export FLASK_APP=app.py

• Then start the flask server by running below command

  flask run -h 0.0.0.0 -p 80

• After running the command, open http://publicip and you should see the demo page displayed. Make sure to use http and not https.
