【问题描述】：
我遇到的问题与其他现有帖子非常相似，除了它们都有相同的解决方案，因此我创建了一个新线程。
问题： 安装 Flannel 后，Master 节点仍处于“NotReady”状态。
预期结果： 安装 Flannel 后，主节点变为“就绪”。
背景： 我在安装 Flannel 时遵循 this 指南
我担心的是我默认使用的是 Kubelet v1.17.2，就像上个月一样（有人可以确认 v1.17.2 是否适用于 Flannel 吗？”
这是在主节点上运行命令后的输出：kubectl describe node machias

您使用的是哪个云提供商？

@ShreePrakash 我没有使用云提供商，我相信虚拟服务器是从我的学校网络运行的
