cri

The kubelet is a local reconcile loop with its own event stream, probe workers and eviction brain. Staff-level candidates can narrate it and explain why Ready status can reflect either reported health failure or missing heartbeats.

It sounds like trivia and screens for something real: whether you understand that a pod is a shared namespace boundary with an owner, not just a group of containers.

Dockershim is gone and the CRI contract decides what a runtime must do. The senior-level part is the shim model: a supervisor process that owns exit codes and stdio so the daemon can die without taking workloads with it.
