We provide a sample app using Flask that you can deply on App Platform.
Then, create an app using your fork of this repo as the source. App Platform will inspect the code, automatically detect the kind of component to create, and use the correct buildpack to create and deploy a container. From there, you can push changes to your fork and see App Platform automatically re-deploy the update to your app.
gunicorn --worker-tmp-dir /dev/shm app:app.
