How to set log level using Flink Docker Image

Hi everyone,

I have a Flink Cluster created from Flink's Docker Image. I'm trying to set
log level to DEBUG but couldn't find how. I know where logback
configuration files are as per documentation:

"The conf directory contains a logback.xml file which can be modified and
is used if Flink is started outside of an IDE."

However I'm not sure how to do that for a running Flink Cluster on
Kubernetes.

Thanks,
G

Thanks, that sounds reasonable. I'll try it out tomorrow :)

You can for example mount the *conf* directory using docker volumes.

You would need to have *logback.xml* and then mount it as *conf/logback.xml
*inside the image. Locally You could do this using *docker-compose.yml*,
for mounting volumes in kubernetes refer to this page:
https://kubernetes.io/docs/concepts/storage/volumes/
