About this track

A lab-only path through production Docker.

Every item in this course is a real environment you launch, operate and repair: guided labs, troubleshooting challenges, three practical exams and a capstone release. There are no video lectures and no reading-only lessons — if you want those, take Hands-on Docker, which covers the same ground with the teaching attached.

Each module closes with a short quiz on what you just did.

You will build, break, diagnose and ship the same application across twelve modules, ending with a production release you take from source to a verified, rolled-back-and-recovered deployment.
