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 [preflight] Running pre-flight checks [WARNING IsDockerSystemdCheck]: detected "cgroupfs" as the Docker cgroup driver.

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
