Docker Compose lets beginners run real applications with a single configuration file instead of long commands. Five small projects teach everything you need for daily use.

Start with a notes app to learn volumes, the mechanism that keeps your data safe when containers are removed or updated.

A website plus a database teaches port mapping and container networking, the shape of most real applications.

Finish with a media server and a dashboard to learn environment variables, restart policies, and organisation. Keep each project in its own folder with a short readme.
