 In kubernetes with gracefull shutdown enabled, pods can stay for long time perriods in a `broken` state. The state results in alerting getting fired by kube-prometheus-stack.
 
+```console
+[FIRING:1] Pod has been in a non-ready state for more than 15 minutes.
+Severity:  warning
+ Description: Pod default/some-container-7fb4c4fbc5-gbjwm has been in a non-ready state for longer than 15 minutes.
+ Details:
+  • alertname: KubePodNotReady • namespace: default • pod: some-container-7fb4c4fbc5-gbjwm • prometheus: observability/kube-prometheus-stack-prometheus • severity: warning
+```

 Most of the `solutions` on the internet describe an uncontrolled deletion of all Pods in `Error` or `Terminated` state.
 Wich I consider as a bad idea, because you will not see anymore if real `Error` Pods are in your system.
