✅ AWS Gateway API Controller Setup Verification Checklist for Kubernetes Gateway API (EKS)
This guide ensures a full production-ready setup for AWS Gateway API Controller integrated with Amazon VPC Lattice and Kubernetes Gateway API. It includes installation, configuration, network validation, and health check debugging.
✅ AWS Gateway API Controller Setup Verification Checklist
📦 A. Cluster & Core Setup
Checkpoint
Command
Expected Output
✅ EKS cluster is running
kubectl get nodes
Shows Ready nodes
✅ Correct context set
kubectl config current-context
Matches your EKS cluster
✅ Kubernetes version
kubectl version --short
Server >= 1.24
🧱 B. Kubernetes Gateway API Installed
Checkpoint
Command
Expected Output
✅ Gateway CRDs installed
`kubectl get crds
grep gateway.networking.k8s.io`
✅ Gateway API version supported
kubectl get gatewayclass
Returns valid list
🔌 C. AWS Gateway API Controller Installed
Checkpoint
Command
Expected Output
✅ Controller pods running
kubectl get pods -n aws-application-networking-system
kubectl describe sa -n aws-application-networking-system
Linked with correct role
🌐 E. VPC Lattice-Specific Setup
Checkpoint
Command
Expected Output
✅ CRDs installed
`kubectl get crds
grep servicenetwork`
✅ ServiceNetwork exists
kubectl get servicenetworks.application-networking.k8s.aws
my-hotel or similar
✅ Gateway references Service Network
kubectl get servicenetworkattachments.application-networking.k8s.aws
Shows status Active
✅ Gateway programmed
kubectl get gateway <name> -o yaml
status.Programmed: True
🧪 F. DNS + Public Access
Checkpoint
Command
Expected Output
✅ VPC Lattice service DNS created
aws vpc-lattice list-services + get-service
Shows dnsEntry.domainName
✅ DNS reachable
nslookup <lattice-dns-name> or dig
Resolves to public IP
✅ TLS termination (optional)
Check if tls.mode: Terminate & ACM cert used
HTTPS enabled
🛠️ G. Readiness for Sample App
Checkpoint
Notes
✅ Deployment and Service manifest ready
Your app must have a Kubernetes Service pointing to the Pod
✅ GRPCRoute or HTTPRoute ready
Should match the Gateway and backend service
✅ Port and Protocols correct
gRPC → port: 443, protocol: GRPC, TLS: Passthrough or Terminate
✅ You’re Now Production Ready!
Your AWS Gateway API Controller setup is now complete, secure, and operational with VPC Lattice. Perfect for gRPC, HTTP, and future service-to-service connectivity.
