Host

Expose a route on multiple hosts.

For more information, see the Kubernetes Gateway API documentation.

Before you begin

1. Set up an agentgateway proxy.
2. Install the httpbin sample app.

Set up host matching

1. Create an HTTPRoute that is exposed on two domains, host1.example and host2.example.

   kubectl apply -f- <<EOF
   apiVersion: gateway.networking.k8s.io/v1
   kind: HTTPRoute
   metadata:
     name: httpbin-match
     namespace: httpbin
   spec:
     parentRefs:
       - name: agentgateway-proxy
         namespace: agentgateway-system
     hostnames:
       - host1.example
       - host2.example
     rules:
       - backendRefs:
           - name: httpbin
             port: 8000
   EOF

2. Send a request to the /status/200 path of the httpbin app on the host1.example domain. Verify that you get back a 200 HTTP response code.
   

   Cloud Provider LoadBalancerPort-forward for local testing

   curl -vi http://$INGRESS_GW_ADDRESS:80/status/200 -H "host: host1.example"

   curl -vi localhost:8080/status/200 -H "host: host1.example"

   Example output:

   * Request completely sent off
   < HTTP/1.1 200 OK
   HTTP/1.1 200 OK
   < access-control-allow-credentials: true
   access-control-allow-credentials: true
   < access-control-allow-origin: *
   access-control-allow-origin: *
   < content-length: 0
   content-length: 0

3. Send another request to the httpbin app. This time, you send it along the host2.example domain. Verify that the request succeeds and that you also get back a 200 HTTP response code.

   curl -vi http://$INGRESS_GW_ADDRESS:80/status/200 -H "host: host2.example"

   curl -vi localhost:8080/status/200 -H "host: host2.example"

   Example output:

   * Request completely sent off
   < HTTP/1.1 200 OK
   HTTP/1.1 200 OK
   < access-control-allow-credentials: true
   access-control-allow-credentials: true
   < access-control-allow-origin: *
   access-control-allow-origin: *
   < content-length: 0
   content-length: 0

Cleanup

kubectl delete httproute httpbin-match -n httpbin
