Afterlife Tales
summary
Covers concrete fixes for container problems: diagnosing RBAC 403s by inspecting Roles/RoleBindings and audit logs, tuning readiness vs liveness probes with a simulated 20s startup (adjusting timeout/period/failureThreshold cuts startup waits from ~42s toward ~32s), protecting replicas with a pod disruption budget (3 replicas, minAvailable=2) during node drains, doing remote Java debug 5005 via kubectl port-forward or Telepresence, swapping unchanged image tags by patching a deployment label, and stopping runaway cronjobs by suspending them and setting backoffLimit correctly.
