rskotla/k3s-flask-project ? reverse-engineered prompt

Build me a small Flask web app that can be run locally with Docker and also deployed to a k3s Kubernetes cluster.

I want a simple site with a clean home page using templates, plus enough structure that it can be tested and expanded later. Please include the Flask app entry point, basic HTML templates, a Dockerfile, and Kubernetes YAML for deployment and service. Also set up a Jenkins pipeline so the app can be built, tested, and packaged in a straightforward CI flow.

Keep it simple and practical, with sensible defaults so I can run it locally without much setup, then push it to the cluster. Add a few basic tests so I know the app is working, and make sure the dependencies are split between normal app requirements and CI requirements. If you need current best practices for Flask, Docker, or k3s, look up the latest docs online and use those.
