Generating token in kubernetes using kubeadm command for adding the worker nodes

 Issue:- Kubeadm provides you a join token command when you first create a kubernetes cluster. But if you dont have that token handy for the future requirement for addition of the worker nodes to increase the cluster capacity ?

Solution:-  you can run the following command which will allow you to generate the full token command which can be used to add the worker nodes to master in the future.

 [centos@kubemaster ~]$ kubeadm token create --print-join-command  

kubeadm join 172.31.98.106:6443 --token ix1ien.29glfz1p04d7ymtd --discovery-token-ca-cert-hash sha256:1f202db500d698032d075433176dd62f5d0074453daa12ccdfffd637a966a771

Once the token has been generated than you can run the command on the worker node to add it in the kubernetes cluster.
