 Once installed, a LoadBalancer Service will be deployed, which creates a NodeBalancer, and an external IP address will be available. To find this external IP address, list your cluster's Services with following command and note the IP address for the `nginx-ingress-controller` in the output under `EXTERNAL-IP`. You will need this IP address for the next step.

 Once your Ingress Controller is installed and DNS records have been created pointing to your NodeBalancer, you need to create a manifest file to create a new Ingress resource. This resource will define how traffic coming from the LoadBalancer service we deployed earlier is handled. In this case, NGINX will accept these connections over port 80, diverting traffic to both of our services via their `hostname`, or domain names:
