Progressive Delivery with the Kubernetes Gateway API

on YouTube ↗20m

" summary

Flagger automates GitOps progressive delivery on Kubernetes by updating Gateway API canary weight fields to split traffic in increments (demo uses 10% steps every 15s up to a 50% promotion threshold) and evaluates Prometheus-backed metric templates like error rate <1% and latency <0.5s to decide rollback or continue. The demo shows a successful canary promoting v6.0.3 to primary. Recent additions include session affinity for sticky canaries and blue/green traffic mirroring for mirrored request comparison.
