Docker lab
Containers are the unit Pods run. Learn mode teaches Docker from images to networking; Break-fix mode has you repair deliberately broken containers at a real docker prompt.
Why this matters: Most Kubernetes problems are really container problems wearing a bigger hat — a bad image reference, a wrong entrypoint, a port that was never exposed. Get fluent here and half of cluster debugging stops being mysterious.
