> I think we should make Flink's logs accessible via {{kubectl logs}} per
> default. Firstly, this is the idiomatic way to obtain the logs from a
> container on Kubernetes. Secondly, especially if something does not work and
> the container cannot start/stops abruptly, there is no way to log into the
> container and look for the log.file. This makes debugging the setup quite
> hard.
> I think the best way would be to create the Flink Docker image in such a way
> that it logs to stdout. In order to allow access to the log file from the web
> ui, it should also create a log file. One way to achieve this is to add a
> ConsoleAppender to the respective logging configuration. Another way could be
> to start the process in the console mode and then to teeing the stdout output
> into the log file.
