库伯奈特斯在日志中没有明确的理由终止吊舱

Question

有办法知道库伯内特斯为什么要终止吊舱吗？

如果我在Google中访问Logging，我能找到的与此事件相关的唯一消息是：

shutting down, got signal: Terminated

另外，状态Terminating中的豆荚从未被终止，其中一些已经处于这种状态超过24小时了。

我不使用livenessProbes或readinessProbes。

我正在使用terminationGracePeriodSeconds: 30

编辑:添加了豆荚的kubectl describe pod <podname>结果，即截至目前为止9小时内的Terminating状态：

Answer 1

至于为什么要终止吊舱，必须是因为您的图像/容器正以成功的状态退出。

试着记录下你的吊舱直到它离开。你也许能从那里看到原因。
