* We prefer Ready:False status instead of restarted pods,Staffan Olsson2017-08-052-12/+0
| | | | | | at least for now, as it allows exec into the pods to investigate. We've been having frequent restarts that are not due to OOMKilled (i.e. not #49). Now failed probes will lead to unready pods, which we can monitor for using #60.

* Default shell on Debian shows the same symptom ...Staffan Olsson2017-07-262-2/+2
| | | | | | | | of not forwarding signals as Alpine did. Kafka logs say nothing, and after 30s the container is terminated. With /bin/bash instead the log indicates shutdown behavior. This reverts commit c188f43cb8a252cd685a4944d35577ebc17a3668.

* Clarifies a gotcha: to mount config with log4j.properties ...Staffan Olsson2017-07-262-0/+4
| | | | | | | you must use /opt/kafka/config, due to how log4j.properites (sometimes tools- or connect-) are resolved by the ./bin scripts. See https://github.com/solsson/dockerfiles/pull/10

* Adds probes, but for Kafka I don't think it indicates readiness...Staffan Olsson2017-06-272-0/+24
| | | | | | | | | | | | | | | 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.
* Reverts to default termination period, and uses bash for "shell form"...Staffan Olsson2017-06-272-4/+4
| | | | | | | | 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.
