Configure route and service

In order to route a request using Kong Gateway we need a Service running in our cluster. Install an echo Service using the following command:

kubectl apply -f https://developer.konghq.com/manifests/kic/echo-service.yaml -n kong

Create an HTTPRoute to send any requests that start with /echo to the echo Service.

echo '
kind: HTTPRoute
apiVersion: gateway.networking.k8s.io/v1
metadata:
  name: echo
  namespace: kong
spec:
  parentRefs:
    - group: gateway.networking.k8s.io
      kind: Gateway
      name: kong
  rules:
    - matches:
        - path:
            type: PathPrefix
            value: /echo
      backendRefs:
        - name: echo
          port: 1027
' | kubectl apply -f -

The results should look like this:

httproute.gateway.networking.k8s.io/echo created

1. Wait for the Gateway to be programmed:

   kubectl wait --for=condition=Programmed gateway/kong -n kong --timeout=5m

   Copied!

2. Run kubectl get gateway kong -n kong to get the IP address for the gateway and set that as the value for the variable PROXY_IP.

   export PROXY_IP=$(kubectl get gateway kong -n kong -o jsonpath='{.status.addresses[0].value}')

   Copied!

3. Test your Service:

   curl -i "http://$PROXY_IP/echo" \
      --no-progress-meter --fail-with-body

   Copied!

   You should see the following message:

   Welcome, you are connected to node kind-control-plane.
   Running on Pod echo-5f44d4c6f9-krnhk.
   In namespace kong.
   With IP address 10.244.0.26.
