<!--
An init container lets you separate initialization details that are important for the overall 
{{< glossary_tooltip text="workload" term_id="workload" >}}, and that don't need to keep running
once the application container has started.
If a pod doesn't have any init containers configured, all the containers in that pod are app containers.

整体而言很重要的初始化细节，并且一旦应用容器启动，它不需要继续运行。
如果 pod 没有配置任何初始化容器，则该 pod 中的所有容器都是应用程序容器。
