google cloud platform - GKE & Stackdriver: Java logback logging format?

Question

I have a project running Java in a docker image on Kubernetes. Logs are automatically ingested by the fluentd agent and end up in Stackdriver.

However, the format of the logs is wrong: Multiline logs get put into separate log lines in Stackdriver, and all logs have "INFO" log level, even though they are really warning, or error.

I have been searching for information on how to configure logback to output the correct format for this to work properly, but I can find no such guide in the google Stackdriver or GKE documentation.

My guess is that I should be outputting JSON of some form, but where do I find information on the format, or even a guide on how to properly set up this pipeline.

Thanks!
