the method

Three tracks. One rhythm.

Every track runs three labs deep — foundations, then persistence, then production. Finish all three and you've shipped nine real applications.

3

Foundations

Pull, run, and connect your first containers — the vocabulary and mechanics everything else builds on.

6

Persistence & Compose

Keep data alive, wire multi-service application stacks, and orchestrate them with one command.

volumescomposeservice discovery
9

Production

Build tiny secure images, scale services gracefully, and harden what you built for the real world.

A lab, not a lecture

Everything you need to go from “what is a container?” to confidently shipping multi-service architectures.

Private Cloud Sandboxes

Every lab session runs in a dedicated, isolated sandbox with guaranteed resource limits — what you run stays private and safe.

Real commands, instant feedback

Run docker and docker compose in a live browser terminal and get instant pass/fail verification against your environment.

AI copilot that teaches

Stuck? Ask the Docker-specialist copilot for hints, command explanations, or deep architectural breakdowns in real time.
