> Looking at [https://github.com/spotify/flink-on-k8s-operator/blob/master/docs/user_guide.md#control-logging-behavior] 
> Something similar could work here as well
> {quote}The default logging configuration provided by the operator sends logs from JobManager and TaskManager to {{{}stdout{}}}. This has the effect of making it so that logging from Flink workloads running on Kubernetes behaves like every other Kubernetes pod. Your Flink logs should be stored wherever you generally expect to see your container logs in your environment.
> Sometimes, however, this is not a good fit. An example of when you might want to customize logging behavior is to restore the visibility of logs in the Flink JobManager web interface. Or you might want to ship logs directly to a different sink, or using a different formatter.
> You can use the {{spec.logConfig}} field to fully control the log4j and logback configuration. It is a string-to-string map, whose keys and values become filenames and contents (respectively) in the folder {{/opt/flink/conf}} in each container. The default Flink docker entrypoint expects this directory to contain two files: {{log4j-console.properties}} and {{{}logback-console.xml{}}}.
