`PreStop` 回调并不会与停止容器的信号处理程序异步执行；回调必须在

可以发送信号之前完成执行。
|

如果 `PreStop` 回调在执行期间停滞不前，Pod 的阶段会变成 `Terminating`

并且一致处于该状态，直到其 `terminationGracePeriodSeconds` 耗尽为止，

并且一直处于该状态，直到其 `terminationGracePeriodSeconds` 耗尽为止，

这时 Pod 会被杀死。
|

这一宽限期是针对 `PreStop` 回调的执行时间及容器正常停止时间的总和而言的。

例如，如果 `terminationGracePeriodSeconds` 是 60，回调函数花了 55 秒钟

@ -214,30 +214,30 @@ The logs for a Hook handler are not exposed in Pod events.
|
|||
If a handler fails for some reason, it broadcasts an event.
|
||||
For `PostStart`, this is the `FailedPostStartHook` event,
|
||||
and for `PreStop`, this is the `FailedPreStopHook` event.
|
||||
You can see these events by running `kubectl describe pod <pod_name>`.
|
||||
Here is some example output of events from running this command:
|
||||
To generate a failed `FailedPreStopHook` event yourself, modify the [lifecycle-events.yaml](https://raw.githubusercontent.com/kubernetes/website/main/content/en/examples/pods/lifecycle-events.yaml) file to change the postStart command to "badcommand" and apply it.
|

Here is some example output of the resulting events you see from running `kubectl describe pod lifecycle-demo`:

### 调试回调处理程序
|
||||
|
||||
回调处理程序的日志不会在 Pod 事件中公开。
|
||||
如果处理程序由于某种原因失败，它将播放一个事件。
|
||||
对于 `PostStart`，这是 `FailedPostStartHook` 事件，对于 `PreStop`，这是 `FailedPreStopHook` 事件。
|
||||
您可以通过运行 `kubectl describe pod <pod_name>` 命令来查看这些事件。
|
||||
下面是运行这个命令的一些事件输出示例:
|
||||
要自己生成失败的 `FailedPreStopHook` 事件，请修改 [lifecycle-events.yaml](https://raw.githubusercontent.com/kubernetes/website/main/content/en/examples/pods/lifecycle-events.yaml) 文件将 postStart 命令更改为 ”badcommand“ 并应用它。
