Confusion in Quiz 3.1

pubudu_sitinamaluwa

This looks contradicting with docs or I have understood this incorrectly.

https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-readiness-probes

Can someone please help me to solve this confusion? Thanks.

Hi @pubudu_sitinamaluwa,

The question, the answer, and the note from the documentation are correct, but once you put them side-by-side things become a bit confusing.
The missing piece of information is that although the readiness probe runs on the container during its entire lifecycle (per the note above), kubelet checks the probe until it passes, and stops checking after that. However, if the probe failure threshold is reached, then kubelet restarts the container and the readiness probing starts all over again.

Regards,

We will update the question to better reflect how the probes work.

Thanks for bringing it up.
