 2. Exposing the Ingress Controller''
 
-
-• Service Type: The Ingress Controller itself is exposed via a Kubernetes Service. This Service needs to be accessible from outside the cluster. There are two common ways to do this:
-- !NodePort: The Service is exposed on a high port (e.g., 30000-32767) on each node's IP address. External traffic can reach the Ingress Controller by hitting any node's IP at this port.
-- !LoadBalancer: If your cluster is running in a cloud environment that supports !LoadBalancer Services, this is a more straightforward way to expose your Ingress Controller. For our setup lets allow the metalLB setup to lease an external IP address that routes traffic to the Ingress Controller.
