Migrating from Ingress to Kubernetes Gateway API | Demo | Nginx Ingress | Istio Ingress

You have referred gatewayclass while creating gateway. What is the prerequisite for creating gatewayclass. Is it enough if I have istio/nginx deployed on cluster and then start referring them in gateways that I create in app namespaces. Will it in turn create a gateway service for me in the same namespace? Please elaborate on this. Thank you!

Yes, If you have a controller that supports Gateway API then you don't need to create any GatewayClass for it, you can simply refer to it with the relevant name. If you have Istio installed you can refer to it in the Gateway resource. Here is a list of supported controllers that implement gateway API specification, you can pick any of them as the controller gateway-api.sigs.k8s.io/implementations
