120 cards
This deck walks you through the foundational building blocks of a Kubernetes cluster, from the humble Pod all the way up through the controllers that manage them and the Services that expose them. The questions cover what each object is, what problem it solves, and how it relates to the others, so you can build a clear mental map of the core API rather than just memorizing isolated definitions.
It's a great fit if you're new to Kubernetes and trying to get comfortable with the vocabulary, or if you're preparing for a certification like the CKAD or CKA and want to drill the basics. Developers and operators who already work with clusters occasionally but want a more confident grasp of the "why" behind the YAML they write will also find it useful.
Because the cards are framed as short questions, try answering out loud or in writing before flipping each one over — active recall like this sticks far better than passive reading. It also helps to study related cards together in small batches (for example, all the workload controllers, or all the Service types), since the differences between them often become clearer when you compare them side by side.
