Probes done right

Stub page

The single most misunderstood K8s feature. Liveness ≠ readiness ≠ startup.

Planned content

  • Startup probe: when your app is slow to boot
  • Readiness probe: 'should I receive traffic?'
  • Liveness probe: 'should I be killed?' (and when NOT to use it)
  • Common anti-patterns (DB checks in liveness, etc.)
