GKE Gateway API Routing Example

This reference example demonstrates exposing workloads via the GKE Gateway API (L7 Internal HTTP Load Balancer).

It includes:

• Gateway resource with gatewayClassName: gke-l7-rilb
• HTTPRoute resource referencing the backend Service

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: internal-http-gateway
  namespace: nginx-ns
spec:
  gatewayClassName: gke-l7-rilb
  listeners:
    - name: http
      protocol: HTTP
      port: 80
      allowedRoutes:
        namespaces:
          from: Same
