Build a StatefulSet with a headless Service, watch ordered Pod creation, verify per-replica PVC naming, scale down and back up, prove stable identity, then roll an image update and roll back using ControllerRevision history.
Run one Pod per node with a DaemonSet, roll an image update, roll back to the previous revision, and restrict coverage to a subset of nodes with a nodeSelector.
Build a ReplicaSet by hand, observe self-healing, then update its template and end up with Pods running different images. Layer a Deployment on top and confirm the full ownership chain.
Build a Pod from scratch, exec into it, try to edit an immutable field, explore all three restart policies, and observe graceful termination.
Six hands-on challenges covering every Kubernetes workload resource. Build Pods, ReplicaSets, Deployments, DaemonSets, StatefulSets, Jobs, and CronJobs by hand and understand the ownership chains that connect them.
