现在一团糟，不知道怎么解决

kubelet 是报这个错误

Sep 15 15:51:54 master kubelet[94723]: E0915 15:51:54.473811 94723 kubelet.go:2183] node "master" not found

我是单节点 master 升级高可用，现在高可用有问题，我就想回到单节点 master

部署方式是什么？ kubeadm ? hyperkube ? 还是手动部署的各个组件container runtime 是使用的 docker 还是 containerd, cri-o ?感觉上像是 kubelet 连不上 apiserver，你可以贴一下 apiserver 的日志类似的问题 https://github.com/kubernetes/kubeadm/issues/1153
