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
