Quick Reference

K8s Probes: Liveness = restart if dead (keep simple). Readiness = receive traffic if ready (check deps). Startup = disable others until started (slow apps). Use separate endpoints. Don't check external deps in liveness. failureThreshold=3, periodSeconds=10 as starting point.

Use When

  • Kubernetes deployments
  • Container health monitoring
  • Service reliability
  • Zero-downtime deployments

Skip When

  • Non-Kubernetes environments
  • Batch jobs
