Basic Python Flask app in Docker which prints the hostname and IP of the container
Launches a Flask web server inside a Docker container. When you visit the page, it displays:
The hostname of the container is 6095273a4e9b and its IP is 172.17.0.2.
This confirms the container is running and shows key networking info -- useful for demos, testing, and learning Docker networking.
