The current documentation on how to get remote logging in GCP to work is thoroughly out-of-date, not to mention needlessly complicated. I have a PR open with the updated documentation, that would come as a sigh of relief to anyone who might want to use it, but would otherwise be turned off by how "tough" it is to setup.
