To reach the ClusterIp from an external computer, you can

open a Kubernetes proxy between the external computer and the cluster

. You can use kubectl to create such a proxy. When the proxy is up, you’re directly connected to the cluster, and you can use the internal IP (ClusterIp) for that Service .
