  title: Contour Gateway GatewayClass API
  description: Contour's implementation of the Kubernetes Gateway API, providing support for GatewayClass, Gateway, HTTPRoute, TLSRoute, and related resources. The Gateway API is the next-generation Kubernetes ingress standard, and Contour implements it alongside the legacy Ingress and HTTPProxy resources. All resources are managed through the Kubernetes API server using standard Kubernetes CRD patterns.
