The Kubernetes API server can be accessed by using a kubeconfig
in kubectl. Copy the admin.tar file from the Administration Dashboard,
uncompress it and export the KUBECONFIG variable or use the --kubeconfig
flag.
For example:
$ scp -i ssh/id_docker root@`terraform output ip_dashboard`:admin.tar .
$ tar xvpf admin.tar
$ kubectl --kubeconfig=kubeconfig get nodes
