 Using this architecture, the **coffee** application is not accessible outside the cluster. We want to expose this application on the hostname "cafe.example.com" so that clients outside the cluster can access it.

 Using these resources we will configure a simple routing rule to match all HTTP traffic with the hostname "cafe.example.com" and route it to the **coffee** service.

 This Gateway is associated with NGINX Gateway Fabric through the **gatewayClassName** field. The default installation of NGINX Gateway Fabric creates a GatewayClass with the name **nginx**. NGINX Gateway Fabric will only configure Gateways with a **gatewayClassName** of **nginx** unless you change the name via the `--gatewayclass` [command-line flag]({{< ref "/ngf/reference/cli-help.md#controller" >}}).
 
-We specify a [listener](https://gateway-api.sigs.k8s.io/references/spec/#gateway.networking.k8s.io/v1.Listener) on the Gateway to open an entry point on the cluster. In this case, since the coffee application accepts HTTP requests, we create an HTTP listener, named **http**, that listens on port 80.
