Readiness-Probe

Why / Howto /

Readiness checks, if container is ready and if it's not READY
- SENDS NO TRAFFIC to the container

Difference to LiveNess

They are configured exactly the same, but use another keyword
- readinessProbe instead of livenessProbe

Example

readinessProbe:
  exec:
    command:
    - cat
    - /tmp/healthy
  initialDelaySeconds: 5
  periodSeconds: 5
