k8s集群中worker节点的ip改变导致notready

Question

老师, 因为worker01节点的ip改变, 导致 status为notready状态

NAME STATUS ROLES AGE VERSION
master01 Ready control-plane,master 48d v1.23.9
worker01 NotReady 48d v1.23.9
worker02 Ready 48d v1.23.9

重启kubelet也不生效, 查看日志发现报错如下, 这个有什么解决方案么?

同学你好，节点IP变化需要重新加入一次，在master节点获取加入命令：

kubeadm token create --print-join-command

在worker节点先kubeadm reset退出，然后执行上述命令返回的加入命令。
