Summary

  • kube-state-metrics has 499 restarts in 6 days due to liveness probe killing the container before it finishes initializing 30+ resource watchers
  • Adds a startupProbe giving KSM up to 185s to initialize before liveness takes over
  • Liveness probe continues with standard timings after startup succeeds

Test plan

  • ArgoCD syncs the change
  • kube-state-metrics pod restarts with new probe config
  • Restart count stays at 0 after rollout

KSM lists/watches 30+ resource types on startup. Default liveness probe
(initialDelay=5s) kills the container at ~35s before caches are built,
causing 499 restarts in 6 days. Startup probe gives up to 185s for
initialization before liveness takes over.
