<!--
Initialization (init) containers are like regular app containers, with one difference: init containers must run to completion before any app containers can start. Init containers run in series: each init container must run to completion before the next init container begins.
-->
Init 容器像常规应用容器一样，只有一点不同：Init 容器必须在应用容器启动前运行完成。
Init 容器的运行顺序：一个 Init 容器必须在下一个 Init 容器开始前运行完成。

<!--
Unlike {{< glossary_tooltip text="sidecar containers" term_id="sidecar-container" >}}, init containers do not remain running after Pod startup.

For more information, read [init containers](/docs/concepts/workloads/pods/init-containers/).

与{{< glossary_tooltip text="边车容器" term_id="sidecar-container" >}}不同，Init 容器在 Pod 启动后不会继续运行。
