hello world flask application == web service

What is it?

Implemented a trivial HTTP "Hello, world!" web application in python Requirements:

• Dockerfile that dockerizes the application.
• The app has a health-check.
• The application must provide metrics endpoint for Prometheus.
• Grafana dashboard with metrics visualization.
• docker-compose.yml that launches the app with all the necessary environment (Prometheus and Grafana).

How build from Dockerfile?

DOCKER_BUILDKIT=1 docker build --ssh default --no-cache -t hello_world:latest -f Dockerfile .

How run docker-compose?

docker-compose up

How can I deploy this app in kubernetes? (Not the best method)
