Keynote: Push It to the Limit: From Canary Deployments to Canary Clusters
summary
Lunar moves from canary deployments to full canary clusters by shifting most state out of Kubernetes and automating failover steps: GitOps with Flux, Route 53 via external-dns, RabbitMQ federation, and a small CLI called Shuttle. Two custom operators — cluster identity controller and routing weight controller — inject cluster-specific config and manage DNS weights. After 17 test failovers the end-to-end procedure shrinks from about four hours to 40 minutes with five manual checks.
