The Great "k8s.gcr.io" Vanity Domain Flip

summary
Two-year effort (late 2018–mid 2020) rewrites Google’s promotion system into a Go-based container image promoter that reads production state in ~30 seconds, models promotions as “edges,” and handles roughly 30,000 images with parallelized deltas. Auditing runs on Pub/Sub → Cloud Run → Error Reporting, backups are incremental every 12 hours to avoid quota blowouts, and the DNS flip finishes in a careful four-day rollout on July 24 with no service-visible failures.
