kubernetes - KubeletNotReady - 初始化 CSINodeInfo 失败

问题描述

在 Ubunutu 18.04 中安装 Kubernetes 集群时出现以下错误。Kubernetes master 已准备就绪。我正在使用法兰绒作为 pod 网络。我将使用 join 命令将我的第一个节点添加到集群中。

更新：

我在工作节点下面注意到

请让我知道如何解决这个问题？

解决方案

我有同样的问题，但是，我的情况是我有一个正在运行的 k8s 集群，突然间，我的一些 k8s 节点上发生了 CISNodeInfo 问题，并且该节点不再在集群中。google了几天，终于得到 Node cannot join #86094的答案

只需编辑 /var/lib/kubelet/config.yaml 即可添加：

featureGates:
  CSIMigration: false

...在文件末尾似乎允许集群按预期启动。
