kgateway, the CNCF Gateway API control plane that succeeded Gloo Edge. Watches Gateway, HTTPRoute, GRPCRoute and its own gateway.kgateway.dev policy CRDs, programs Envoy over xDS and provisions the proxy fleet itself. Pairs with the QuenchWorks kgateway-envoy data plane. Ships two minor lines because 2.2.x pins its amd64 data plane to a vendor fork of Envoy this catalog does not rebuild. Carries the Wolfi envoy binary for the strict xDS validation path.
