kubernetes-使用kubeadm添加node节点

node节点服务器需要安装好 kubeadm, kubelet 和 kubectl:

使用kubeadm join 命令即行,使用master节点kebeadm init时的提示:

root@boke-node:~# kubeadm join 192.168.17.180:6443 --token abcdef.0123456789abcdef \
>     --discovery-token-ca-cert-hash sha256:ea37964dc96f76f3e658b27ffdc220f60ced82de387aafd8effafe9618f5e6cb

This node has joined the cluster:
* Certificate signing request was sent to apiserver and a response was received.
* The Kubelet was informed of the new secure connection details.

Run 'kubectl get nodes' on the control-plane to see this node join the cluster.

　master节点使用kubectl get nodes命令查看是否添加成功

kubectl get nodes
# 打印出node节点便代表成功了   NAME是根据主机名来定义的
