Labs, not lectures.

Every course is a sequence of tasks in a live environment. You read two lines, you do the thing, the verifier checks it — and an AI tutor is there when you're stuck. Here is exactly what that looks like, start to certificate.

Container Foundations

7 tasksBeginner45 mcertificate
  • Run, tag, exec into, port-map and inspect any container
  • Understand what makes a container isolated
  • No prior Docker needed — a real terminal in the browser
Start lab →
What you'll have at the end
  • A running nginx container you published to port 8080
  • 7 / 7 tasks verified against your own containers
  • A certificate with a public verification link

Every course in the catalog has this exact shape — tasks, a live environment, a verifier, a certificate.

Provisioning your environment
✓ sandbox allocated 0.3 s
✓ Docker daemon started 4 s
✓ VS Code + terminal ready 31 s

Nothing to install. Works on a college lab PC. The same environment every time, so you never lose twenty minutes to setup.

7What makes it isolated

Run your first container

Pull hello-world and run it. Then run nginx detached and confirm it's up.

student@lab:~$ docker run hello-world
Hello from Docker! This message shows that your installation appears to be working.
student@lab:~$ docker run -d --name web nginx:1.27
9e1f…c2a7
student@lab:~$ docker ps --format "{{.Names}} {{.Status}}"
web Up 3 seconds
Verification · task 3 of 7
Container web exists
State is running
docker inspect shows image nginx:1.27
You ran inspect, not just ps
Verify step
What the verifier does
  • Connects to your environment, not a model answer
  • Inspects the container, the image, the port mapping
  • Reads your shell history for the commands the task required
  • Tells you exactly which check failed, and why

Attempts are free and unlimited. Retries are recorded — honestly — on the lab report.

Ask the AI tutor
AI tutor · knows your current step, never gives the answer
AI tutor · hint 1 of 3
Your port mapping is right, but the container that owns it isn't running any more. Something stopped it after you started it.
scoped to task 4 · never the answer
AI tutor · hint 2 of 3
Run docker ps -a — look at the STATUS column for web. What does "Exited (0)" tell you about the command it ran?
verified · task 4
You restarted web with -d and a foreground process. All three checks pass.

The link works for anyone — a recruiter sees the tasks that passed, when, and how many attempts. Share it on LinkedIn or put it on your resume.

The catalog

Six areas. Each one a path, not a pile.

Courses come in numbered series that build on each other and end in a capstone. Pick an area to see its series and every lab in them.

Inside a lab

Five things every lab has.

The same anatomy across all 117, so the second lab feels familiar and the fiftieth feels fast.

Tasks5–12 per lab. Two lines of direction each. Ordered, not skippable.
EnvironmentVS Code + terminal in the browser, or a real AWS account. Ready in seconds.
VerifierChecks the artefact, not the answer. Tells you which check failed and why.
AI tutorHints scoped to your current step. Reveals the solution only after two verify attempts.
CertificateIssued when every task passes. Public link lists the labs.

Start with Docker. Or Linux. Or AWS.
