How to set log level using Flink Docker Image

[Guilherme Nobre]

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

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/
