Dynamic Service Discovery: Istio as Gateway


I am using Istio as an Ingress Gateway on K8s where external traffic are routed through the Gateway to the appropriate services. I have successfully created a Gateway and a VirtualService as described in Istio / Ingress Gateways.

My question is if I develop a new service “abc” (that has a new URL endpoint) and there are no specific routing rules to apply, do I have to modify the VirtualService configuration to allow the traffic to reach “abc”?

Thanks All!
