Goal

Understand Gateway API as a modern routing layer with GatewayClass, Gateway and HTTPRoute.

What Is Done

The normal app lives under manifests/. Gateway API resources live separately under gateway-api/ because they require CRDs and a Gateway Controller.

Typical Commands

kubectl apply -f manifests/
kubectl kustomize gateway-api/
kubectl apply -f gateway-api/
kubectl get gatewayclass
kubectl get gateway,httproute -n gateway-lab

Validate Success

• Workload and Service exist in namespace gateway-lab.
• HTTPRoute points to Service gateway-web.
• GatewayClass.spec.controllerName matches the installed controller.

Common Mistakes

• Gateway API CRDs are not installed.
• Placeholder controllerName is not adjusted.
• Gateway and HTTPRoute are expected to work without a controller.
