Overview
Flagger gradually shifts traffic to a new version of a service while continuously checking metrics - error rate, latency, custom business metrics - and automatically rolls back if those metrics degrade, removing the manual babysitting typically required for canary releases. It integrates with service meshes like Istio and Linkerd (also in this catalog) or ingress controllers to control traffic splitting.
Flagger is a fit for teams that want automated, metrics-driven progressive delivery rather than manually watching a canary rollout, commonly paired with Flux (also in this catalog), from the same project family.
