Strimzi-kafka-operator: No way to set the debug level up

[datngoews]

Is there any way to set the ZOOKEEPER_LOG_LEVEL env?

https://github.com/strimzi/strimzi/blob/5d395aeb1ba55a4299fcdccf357cd6d0c418c167/docker-images/zookeeper/scripts/zookeeper_run.sh#L32

Same issue for the KAFKA_LOG_LEVEL

Good point. We have it supported in the containers it self, but not exposed this as user configurable to the users. Thanks for raising this issue - we will add it to our backlog.

Or any community effort with a PR is well accepted ;)

@scholzj or @ppatierno anything in the pipe on your side or is it worth I take a look right now ?

[ppatierno]

@prune998 it isn't high priority on our side so if you want, a PR will be really welcomed! :)

Well, the way I was thinking of this was :

• change the startup script in the Docker image to template the log4j.properties file
• change the controler to set an ENV VAR with the needed log level, which is used by the startup script.

Any better thought ?

[scholzj]

Yeah, I think that would be a good start. I think in a long term there might be a need for more flexibility than just log level. But that can be done later.

This has been now implemented through a different issue and can be closed.
