Kubernetes 服务器重新启动后群集工作节点未就绪

当我重新启动主节点和工作节点时，工作节点将从就绪变为未就绪

kubectl get节点的结果

如何检查此问题？

尝试重新启动节点的

kubelet

，该节点处于

notReady

状态，它可能会解决您的问题

下面的命令可以提供帮助：

systemctl restart kubelet

节点未就绪时的kubectl节点日志是命令

kubectl logs node

？对不起，我的意思是kubelet logs有太多消息，我找不到任何有用的错误输出。你能得到kubectl的输出来描述节点名吗？你能在kubelet日志中注册吗？此外，还要对kubelet日志中的任何错误进行grep。
