kubernetes - Kubernetes pod 事件显示为“<none>"</none>

问题描述

我们正在调查与 Azure Kubernetes 服务上的 pod 启动缓慢有关的问题。一旦 Pod 启动完成，我们就无法看到历史事件。最新的事件日志显示为<none>。

这是一个例子：

sshuser@sandbox-ubuntu-vm:~$ kubectl get pods

是否定期清除事件日志？当 pod 状态为时，我们可以看到事件，但是在 pod 进入某个状态ContainerCreating后不久（未知多长时间），事件就看不到了。Running

Kubernetes 版本是 1.14.8。

任何帮助是极大的赞赏。

谢谢。
