Pod在Kubernetes中启动但不工作 [英] Pods starting but not working in Kubernetes

问题描述

创建了具有3个Pod的Kubernetes群集部署，所有部署都运行正常，但在尝试运行它们时无法执行此操作，尝试对Describe部分中的Pod的IP(内部)执行curl操作时，我可以看到此错误。卷"；default-Token-twhht"；的SetUp失败：同步机密缓存失败：

以下错误：

推荐答案

您可以向Pod的服务帐户添加额外的RBAC角色权限，参考123。

还要确保您已设置工作负荷标识，请参考4。

当apiserver负载较高时也会发生这种情况，您可以使用更多较小的节点来扩展Pod并增加资源请求。
