canonical/paas-charm ? reverse-engineered prompt

Build me a project that helps me take a normal web app, like Flask, Django, FastAPI, Go, Express, or Spring Boot, and turn it into something I can deploy on Kubernetes without doing all the ops work myself.

I want it to automatically create the container image and the charm files, then let me pack and deploy the app with Juju. It should also make it easy to connect the app to common things like a database and ingress, so I can get the app online and serving traffic quickly.

Please include clear docs for getting started with each supported framework, plus examples I can follow. If anything depends on the latest Charmcraft or Rockcraft docs, look up the current guidance online and keep the setup steps simple.
