Hands-on Kubernetes labs

Exam-style tasks for the performance-based certifications, run on a real kubeadm cluster on your own Mac with the GoldenKube CLI and graded locally. Each card shows the task's domain, the cluster topology it needs, the recommended time and its points; the detail page has the full task text.

How to run a lab

  3. Start a scenario with its id, solve the task on the cluster, run goldenkube submit.

Grading happens on your machine and is practice feedback, not an official score. Tasks are public; hints, reference solutions and grader internals are not.
