Did you run the join command in your Slave/Worker node that you get from your master node?

Hi@Surya,

I think you did not configure your overlay Network. That's why your worker node is not able to connect to your master node. In your master node run the below-given command.

$ kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

I hope this will help you.
