One or more {{< glossary_tooltip text="containers" term_id="container" >}} that are typically started before any app containers run.

Sidecar containers are like regular app containers, but with a different purpose: 
the sidecar provides a Pod-local service to the main app container.
Unlike {{< glossary_tooltip text="init containers" term_id="init-container" >}}, sidecar containers
continue running after Pod startup.

Read [Sidecar containers](/docs/concepts/workloads/pods/sidecar-containers/) for more information.

边车容器与常规应用容器类似，但目的不同：边车为主应用容器提供了一个 Pod 内的本地服务。
与{{< glossary_tooltip text="Init 容器" term_id="init-container" >}}不同，边车容器在 Pod 启动后继续运行。
