  容器环境变量提供了 name=value 形式的、在 {{< glossary_tooltip text="pod" term_id="pod" >}} 中运行的容器所必须的一些重要信息。
  
<!--more-->
<!--
Container environment variables provide information that is required by the running containerized applications along with information about important resources to the {{< glossary_tooltip text="containers" term_id="container" >}}. For example, file system details, information about the container itself, and other cluster resources such as service endpoints.

  容器环境变量为运行中的容器化应用提供必要的信息，同时还提供与 {{< glossary_tooltip text="容器" term_id="container" >}} 重要资源相关的其他信息，例如：文件系统信息、容器自身的信息以及其他像服务端点（Service endpoints）这样的集群资源信息。
