Check the node:
[root@unicanode1 docker]# kubectl get secrets
error: stat /root/.kube/config: not a directory

Means setup was incomplete, need to do the following:
[root@unicanode1 ~]# mkdir -p $HOME/.kube

On master:
[root@unicamaster .kube]# scp -r config unicanode1:/root/.kube
root@unicanode1's password:
config

On node:
[root@unicanode1 .kube]# ls -la
total 8
