I think I'm going to start drawing a hard line on these reviews. You can cc me if it helps, but they must be sent to a Google SWE on the appropriate team, cloud logging in this case.

Who is your point of contact on the logging team? If there is no such person we need to find somebody.

Looks like that's @simonz130 for this PR? That's fine then, but please wait for his approval.

LGTM but you should get an approval from @simonz130

Hi there, any chance of having this merged anytime soon? Thanks

Any chance of merging this soon? Fluentd records these values by default in GKE, but the GCP Logback appender doesn't because of this lack of metadata. This PR will fix that problem and be very helpful to our ability to query this log data.
