Pod 在 Kubernetes 中启动但不工作

创建了具有 3 个 Pod 的 Kubernetes 集群部署，并且全部运行良好，但是当尝试运行它们时无法做到这一点，尝试在描述部分中执行卷曲 Pod 的 Ip（内部），我可以看到此错误“” MountVolume.SetUp failed for卷“default-token-thht”：无法同步秘密缓存：

错误如下：

您可以向 Pod 的服务帐户添加额外的 RBAC 角色权限，参考1 2 3.

还要确保您已设置工作负载身份、参考4.

当 apiserver 高负载时也会发生这种情况，您可以有更多较小的节点来分散您的 pod 并增加您的资源请求。
