工作节点在 Kubernetes 中始终显示 NotReady 状态

Posted 2023-03-16

【中文标题】工作节点在 Kubernetes 中始终显示 NotReady 状态

【英文标题】：Worker nodes display always NotReady status in Kubernetes

【发布时间】：2018-04-18 17:50:54

【问题描述】：

当我加入Kubernetes集群的worker节点时，worker节点的STATUS显示为NotReady，节点的ROLE显示为无（使用命令kubectl get nodes）。我在主节点和工作节点上使用的 Kubernetes 版本是 v1.8.2。我使用的 Docker 版本是17.03.1-ce。工作节点上的 Kublet 登录如下：
