I am using the latest k8s version: 1.16.0.

kubeadm init --pod-network-cidr=10.244.0.0/16 --image-repository=<some-repo> --token=TOKEN --apiserver-advertise-address=<IP> --kubernetes-version=1.16.0

This is the command I am using to initialize the cluster

The current state of the cluster.

master   NotReady   master   42m   v1.16.0
slave1   NotReady   <none>   39m   v1.16.0
slave2   NotReady   <none>   39m   v1.16.0

Please comment if you need any other info.
