Answer 1

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 .

For EKS, you can take a look at the source . If you want to try out installing k8s, you can start with kubeadm or kops . For load balancer, you can checkout this source .

Answer 3

In GKE you can define services to expose or to make accessible the applications defined in the cluster. There are several kinds of services one of them is a LoadBalancer service , this can have an external IP address.
