In this scenario, We're going to proxy from k8s to ubuntu.com

Follow the below steps to do this scenario

Create Gateway-Class and Gateway resources

kubectl apply -f kong-gateway.yml

Create a Service with type ExternalName to proxy to ubuntu

kubectl apply -f external-service.yml

Create HTTPRoute resource

kubectl apply -f http-route.yml

Test the routing rule

Make sure hostname ubuntu-from-k8s.kong is available in your /etc/hosts and points to external-ip of kong-gateway-proxy service and then open your browser and type http://ubuntu-from-k8s.kong. You'll see that your request is routed to ubuntu.com.
