Create a Route with Kong Gateway Operator and Kong Ingress Controller

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

Run kubectl get gateway kong -n default 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}')

Note: if your cluster can not provision LoadBalancer type Services then the IP you receive may only be routable from within the cluster.

Make a call to the $PROXY_IP that you configured.

 curl "$PROXY_IP/echo"

 curl "$PROXY_IP/echo"

You should see the following:

 Welcome, you are connected to node king.
 Running on Pod echo-965f7cf84-rm7wq.
 In namespace default.
 With IP address 192.168.194.10.
