KubeletNotReady - 无法初始化 CSINodeInfo

Question

在 Ubunutu 18.04 中安装 Kubernetes 集群时出现以下错误。 Kubernetes 主节点已准备就绪。 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：

我在下面的工作节点中注意到

请让我知道如何解决这个问题？

Answer 1

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，CISNodeInfo 问题发生在我的某些 k8s 节点上，并且该节点不再在集群中。 用google搜索了几天，终于得到了Node无法加入的答案#86094

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。

安装 Kubernetes 的链接

此链接仅适用于具有 1 个主节点的 1 个集群。 如果要添加工作节点。 您需要在主节点的 /etc/hosts 文件中指定您的 IP 和机器名称。 然后设置你的 kubernetes master。 一旦启动。 然后将您的工作节点加入主节点。 确保在工作节点中安装 kubectl 和 docker。 如果您只希望 master 管理 kubernetes 集群，请跳过共享链接的第 26 步。
