Kubernetes: The Second Week
summary
Covers concrete second‑week skills: how Kubernetes enforces resource quotas and QoS classes so best‑effort pods get evicted first, how lifecycle hooks and signal handling work (postStart/preStop and catching SIGTERM but beware the 30‑second SIGKILL timeout), when to use init containers vs postStart, practical sidecars that refresh content (example: git clone loop every 15s), plus jobs/cronjobs, daemonsets, affinities, taints/tolerations, secrets as base64, and configMaps.
