Certified Kubernetes Administrator
CKA practice questions, dealt by the exam blueprint
Hands on a real cluster, at a command line, with the documentation open. So this drills typed kubectl, task chains graded on a simulated cluster and tried on a live one, and a full mock under the same conditions.
flashkube is a flashcard game for Kubernetes certification. Miss a card and it comes back sooner; answer it well and it rests. That is spaced repetition, and it is the whole engine.

How many CKA cards are there?
5 islands · 15 landings
248 cards written for CKA, across 5 islands and 15 landings — counted from the cartridge itself, not written into this sentence. Cards are tagged per exam, so this is what a CKA candidate actually gets, not the whole library.

How does the CKA exam run, and what does that change?
Hands on a real cluster, at a command line, with the documentation open.
So the cartridge drills typed commands and finding the answer in the documentation alongside the recall underneath them — the recognition that makes your lab hours count. And task chains: multi-step kubectl work graded on a simulated cluster by what it ends up holding, which is the exam's own rule.
Use a lab for the cluster. Use flashkube for everything you will forget between now and the exam — it is the other half of the same preparation, not a substitute for the first.
What comes after CKA?
A finished CKA route hands you to CKS, on the same cartridge. It also holds the skills shelf: the platform stack and the observability skill, built on a generic two-cluster production platform and graded at a terminal; and the K9s tender, a drill over a tool's own keys with no clock — for the job after the paper, and nothing bought separately.
What does CKA prep on flashkube cost?
$29, paid once. Nothing renews and nothing lapses — and every card written after you buy is already yours. Three islands of free water, from wherever you land, and ten CKA questions dealt by the blueprint free, with no account.
