简单地说，我咀嚼了我的kubeadm集群，并试图从头开始(我无法对集群进行适当的拆卸，这就是为什么我被迫走kubeadm reset和sudo yum remove kubeadm kubectl kubelet kubernetes-cni kube*的这条路径，减去将节点从集群中移除的原因)。

我删除了所有软件包(运行在RHEL 7上)，现在正在尝试重新安装，但在启动时获得了错误：

我看到的关于这个错误的每一篇文章都指出，由于我没有运行/var/lib/kubelet/config.yaml，所以丢失了这个文件( kubeadm init )，但是我没有创建一个主节点--我只想像运行安装-kubeadm-kubelet-和-kubectl一样运行这个新的安装。

我漏掉了什么明显的东西吗？我不记得在几个月前的初始安装中启动kubelet service之前在每个节点上运行过D8，另外，在安装软件包的说明中，没有哪个地方说要执行Kubeadm init.。

还要注意的是:在我以前的主节点上，在尝试重新安装和启动kubectl之后，我得到了错误：

但是，我以为我通过做kubeadm reset删除了所有的东西？

我确实删除了前主节点( calico )上的sudo rm -rf /var/etcd/calico-data文件夹，然后重新启动了kubectl，现在正在获取此错误：
