Choose a direction. Build your confidence.

Build the core skills the Certified Kubernetes Application Developer exam tests, in order: workloads, Pod composition, configuration, resources, health, batch and networking — on a real cluster.

You get a ticket, not a tutorial. Diagnose and fix real, broken workloads under pressure — a dead Service, a port mismatch, a bad config release — the way on-call actually works.

Operate a cluster the way the Certified Kubernetes Administrator exam expects — workloads, scheduling, storage, autoscaling, quotas and access — everything that runs on a single cluster, building to a timed simulator.

Harden a real cluster the way the Certified Kubernetes Security Specialist exam expects: least-privilege RBAC, then policy-based admission control.

The Kyverno Certified Associate core: write policy-as-code that validates, mutates and generates Kubernetes resources at admission — on a real cluster with Kyverno enforcing.

Get paged, diagnose a genuinely broken cluster, and fix it under time pressure — on real control-plane internals, not a simulation.
