  生命周期钩子暴露{{< glossary_tooltip text="容器" term_id="container" >}}管理生命周期中的事件，允许用户在事件发生时运行代码。
  <!--
  The lifecycle hooks expose events in the {{< glossary_tooltip text="Container" term_id="container" >}}container management lifecycle and let the user run code when the events occur.

针对容器暴露了两个钩子：PostStart 在容器创建之后立即执行，PreStop 在容器停止之前立即阻塞并被调用。
<!--
Two hooks are exposed to Containers: PostStart which executes immediately after a container is created and PreStop which is blocking and is called immediately before a container is terminated.
