The developer practice pack
Self-paced / one paymentGet the project.
Work through the incidents.
Deploy an application, investigate its failures, and keep a record of your repairs. The pack includes everything below.
Four guided lessons
An application deployment
Connect a frontend, API, PostgreSQL database, and Ingress. Use the browser simulator or take the supplied source into a local cluster.
Five core cases + five challenges
Troubleshooting labs
Use the terminal, live resource map, and manifest editor. Every case checks your repaired resources and asks why the fix works.
- 01The silent release
- 02Healthy, but unreachable
- 03Startup blocked by configuration
- 04Running is not ready
- 05Back to a known good state
Downloadable resources
Your notes and field guide
Export your lab notes, pinned command output, and verification results. Keep the investigation checklist, annotated manifest, and handover template for reference.
Before you buy
Is this for me?
This is for software engineers whose team uses Kubernetes, or who are moving to one that does. Some experience writing software is enough to start. The free foundations introduce the Kubernetes concepts used in the project and labs.
What does the pack add to the free lessons?
The free lessons walk you through commands and repairs. The paid labs start with a broken deployment for you to investigate. Each includes hints, a two-fault challenge, and checks of the repaired resources. The pack also includes the application project and downloadable field guide.
Do I need a cluster or a cloud account?
The labs run in your browser. The optional local project uses Docker, kubectl, k3d, and Helm. The browser simulator models resource state without running real containers or network traffic.
How do I get access?
Pay once through Stripe, then open the sign-in link sent to your purchase email. Use the access form below whenever you return on another browser. Existing Zen Pro purchases include the pack.
Is my progress saved?
Lesson and lab progress is saved in this browser. Your purchase works across devices, but progress does not sync between them. Clearing browser storage clears the saved progress.
The course covers application workflows. It does not prepare you for CKA or CKAD certification exams. Browser checks verify simulated resource state; use the optional local project to practice with real containers and requests.
