问题场景：

        本地测试由于之前安装过K8S今天重启无法使用了，于是重新安装了一下，子节点加入主节点报错：

问题解决办法：

        先说一下原因：是之前加入过，有一些残留文件但是删除了还是没有删除干净。那就需要reset一下，执行命令即可：

[root@node1 ~]# kubeadm reset -f

此时再次join没有问题成功。

补充：

1、调试技巧还是在join下增加一个输出细节级别 --v 方便调试：

[root@node1 ~]# kubeadm join 192.168.1.100:6443 --token mk6uf1.eef01he2iqok22tm         --discovery-token-ca-cert-hash sha256:e0ad6e494a6c6b192b88f136a96c421e28d63b235b54091bf04faa5db36aa609 --v=10

2、一键清理并reset，之心过后直接可以运行join：

[root@node1 ~]# rm -rf /root/.kube && rm -rf /etc/cni/net.d && rm -rf /etc/kubernetes/* && kill -9 $(lsof -i:10250 |awk 'NR>1 {print $2}') && kubeadm reset -f
