Add Gateway and HTTPRoute manifests to route external traffic to the dsh-gateway service (dsh-demo:8080). - Gateway dsh-gateway: HTTPS listener with TLS termination against a dsh-demo-tls cert secret. - HTTPRoute dsh-gateway: hostname -> dsh-gateway:8080. - Example TLS secret manifest + README with apply/verify/rollback.

Gateway API — external access for dsh-demo/dsh-gateway
Exposes the dsh-gateway service (dsh-demo, port 8080) outside the cluster
using the Kubernetes Gateway API (Traefik Gateway controller).
Resources
| File | Kind | Purpose |
|---|---|---|
gateway.yaml |
Gateway |
HTTPS listener with TLS termination |
httproute.yaml |
HTTPRoute |
Routes the hostname → dsh-gateway:8080 |
tls-secret.yaml.example |
Secret |
Example TLS cert secret (not applied as-is) |
Prerequisites
- Hostname — replace the placeholder in
httproute.yamlwith the real FQDN. - TLS secret — create
dsh-demo-tlsindsh-demo(seetls-secret.yaml.example). - Ingress and DNS — configure the upstream ingress and public DNS for the hostname.
Apply
kubectl diff -f gateway-api/dsh-demo/
kubectl apply -f gateway-api/dsh-demo/ --dry-run=server
kubectl apply -f gateway-api/dsh-demo/
⚠️ A write-enabled kubeconfig is required to create Gateways and HTTPRoutes.
Verify
kubectl get gateway dsh-gateway -n dsh-demo -o yaml # expect Programmed=True
kubectl get httproute -n dsh-demo -o wide # expect Accepted
kubectl get endpoints dsh-gateway -n dsh-demo # backend present
kubectl -n dsh-demo exec deploy/dsh-gateway -- wget -qO- http://localhost:8080/healthz
Rollback
kubectl delete -f gateway-api/dsh-demo/
Notes
- No
ReferenceGrantis required: the Gateway, HTTPRoute, and backend Service are all indsh-demo. - The backend (
dsh-gateway) serves plain HTTP on 8080 and has a/healthzprobe.
