\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	which might not matter because we no longer have a loadbalancing service. These probes won't catch all failure modes, but if they fail we're pretty sure the container is malfunctioning. I found some sources recommending ./bin/kafka-topics.sh for probes but to me it looks risky to introduce a dependency to some other service for such things. One such source is https://github.com/kubernetes/charts/pull/144 The zookeeper probe is from https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/ An issue is that zookeeper's logs are quite verbose for every probe.

\| \| \| \| \| \| \| \|	as Alpine's /bin/busybox (ash) does not forward signals, according to https://pracucci.com/graceful-shutdown-of-kubernetes-pods.html The reason for the termination period change is that we haven't observed any termination behavior yet so we can't know how slow it might be.
