The Fine Art of Canary Deployments
summary
Step‑by‑step setup for canary rollouts using Kubernetes replica sets, Kubernetes replica sets and label‑based services; routing via Istio/Envoy routing with weighted virtual services (examples: 80/20 and 90/10) and 10% incremental promotion; automated gating with Flagger (Prometheus metrics: request rate, error rate, latency) and Argo Rollouts for declarative pause/promote stages; manual AB stress tests (ab) and Prometheus scraping shown; examples include recreate, rolling, blue‑green, canary strategies and how to rollback when thresholds fail.
