Configure Kubernetes logs in different path with Spring Logback

spring logging kubernetes logback fluentd

You need to:

move that file onto an emptyDir volume (or hostPath I guess but use emptyDir) and then
run fluentd/bit as a sidecar which reads from that volume and
forwards to the rest of your fluentd setup.

spring logging kubernetes logback fluentd

In the dockerfile for the spring boot app create a directory where logs will be written
In the logback xml file have a FileAppender which will write logs in that directory path
Have the logback xml file as part of the jar file in resources folder.
Add Fluentd sidecar into the pod spec of the spring boot app
Configure Fluentd sidecar to tail logs from the log file written in that directory path.
