I just new in K8s. I try to self deploy k8s cloud in internal company server. And I have question how to I setup my K8s can allocation External IP for Service with Loabalancer. May you tell you how it work in GKE or EKS?

Updated base on your comment.

What I mean how to EKS or GKE behind the scenes allocation ip, what is a mechanism?

Here's the EKS version and here's the GKE version. It's a complex thing, suggest you use these materials as the starting point before diving into technical details (which previous answer provided you the source). In case you thought of on-premises k8s cluster, it depends on the CNI that you will use, a well known CNI is Calico.
