Overview

Flagger is a CNCF progressive delivery operator that automates canary, blue-green, and A/B rollouts on Kubernetes. Instead of flipping all traffic at once, it shifts a slice, watches metrics from Prometheus through your service mesh, and rolls back automatically if error rates or latency drift. It suits SRE and platform teams already running Istio, Linkerd, or an ingress that can split traffic. As open source it costs nothing, but the real investment is in defining meaningful metric thresholds and wiring up the mesh that Flagger depends on.
