Kubernetes in Public Cloud (goilerplate.com)

# Check the IP of the Kubernetes control plane.
$ kubectl cluster-info
Kubernetes control plane is running at https://10.0.0.8:6443
CoreDNS is running at https://10.0.0.8:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
