3. Set the current node as the master node
kubernetes network policy : 'Calico'

./master.sh

token saved at k8s-token.txt
This token has no expiry date

4. Add worker node

example

sudo kubeadm join 10.0.2.4:6443 --token y066kk.g60l4xjdbgb5k4t7 \
        --discovery-token-ca-cert-hash sha256:c58fdb2113aae3f8fab21ed88accf5720608c13694577f73c4ed56fb7907b706

If you add Worker Node, you should find command at Master's k8s-token.txt
And you should prepend 'sudo' to the command

kubectl apply -f nginx.yaml
