Kubernetes Cookbook - Second Edition

Getting a node involved

Let's log in to your Kubernetes node to join the group controlled by kubeadm:

1. First, enable and start the service, kubelet. Every Kubernetes machine should have kubelet running on it:

$ sudo systemctl enable kubelet && sudo systemctl start kubelet

2. After that, fire the kubeadm join command with an input flag token and the IP address of the master, notifying the master that it is a secured and authorized node. You can get the token on the master node via the kubeadm command:

// on master node, list the token you have in the cluster$ sudo kubeadm token listTOKEN                     TTL       EXPIRES                     USAGES                   DESCRIPTION                                                EXTRA GROUPSda3a90.9a119695a933a867 6h 2018-05-01T18:47:10-04:00 authentication,signing The default bootstrap token generated ...
