What is Gateway API?
The next-generation Kubernetes API for managing ingress and routing, replacing Ingress.
The Kubernetes Gateway API is the next-generation standard for traffic routing in Kubernetes, designed to replace the Ingress API. It's more expressive: GatewayClass (infrastructure), Gateway (listener), and HTTPRoute/GRPCRoute (routing rules) are separate resources with clear role separation. It supports advanced features like traffic splitting, header manipulation, and cross-namespace routing that Ingress can't express. Most major ingress controllers (nginx, Istio, Envoy Gateway) now support it.
