jedcunningham opened a new issue #15259:
URL: https://github.com/apache/airflow/issues/15259
Pre Kubernetes v1.20, livenessprobe `timeoutSeconds` wasn't functional, and
defaults to 1 second. The livenessprobe for the schedule, however, takes longer
than 1 second to finish, so the scheduler will have consistent livenessprobe
failures when running on v1.20.
```
...
Warning Unhealthy 23s kubelet Liveness probe failed:
```
https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#configure-probes
**Kubernetes version**: v1.20.2
**What happened**:
Livenessprobe failures keeps restarting the scheduler due to timing out.
**What you expected to happen**:
Livenessprobe succeeds.
**How to reproduce it**:
Deploy the helm chart on v1.20+ with the default livenessprobe
`timeoutSeconds` of 1 and watch the scheduler livenessprobe fail.
