Hi Daniel, I believe it is possible to use logback for jobs submitted by flink kubernetes operator but I have not found an out-of-box solution either. I tried following steps:
* Create custom flink image following https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/advanced/logging/#configuring-logback to add necessary jars/xmls and use the custom image * Use -Dlogback.configurationFile=<file> to specify the logback.xml(mounted or packaged in the image) in spec.flinkConfiguration * Submit the job Best, Biao Geng From: Daniel Fischer <d.fischer...@gmail.com> Date: Wednesday, July 13, 2022 at 6:44 PM To: user@flink.apache.org <user@flink.apache.org> Subject: Kubernetes Operator - Logging Hi, I have a job running in Kubernetes that I'm looking to migrate to the new Kubernetes Operator https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/operations/metrics-logging/. My question is about logging. My job currently uses logback, but reading through the documentation I'm not seeing a way to use anything other than log4j. My questions are: 1. Is it possible to use a logging framework other than log4j with the kubernetes operator? 2. Is it possible to configure logging through the FlinkDeployment? The documentation seems to read that logging must be configured when installing the operator. https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-main/docs/operations/metrics-logging/#logging Thanks!
