How to save Connect logs to file

[mmuehlbeyer]

hey,

I’ve tested different settings in my local env, not yet a working solution but probably a good point to start.

I’v extended the Dockerfile with the following

COPY common-logging-6.2.1.jar /usr/share/java/kafka/common-logging-6.2.1.jar
COPY confluent-log4j-extensions-6.2.1.jar /usr/share/java/kafka/confluent-log4j-extensions-6.2.1.jar
COPY kafka-connect.properties /etc/confluent/docker/kafka-connect.properties.template

get the jars from
https://mvnrepository.com/artifact/io.confluent/common-logging
https://mvnrepository.com/artifact/io.confluent/confluent-log4j-extensions

and then start the container with
-e CONNECT_LOG4J_ROOT_LOGLEVEL="DEBUG, connectAppender, stdout" \

for reference, similar topic but not on docker:
