+<!-- overview -->
+<!--
+Each container that you run is repeatable; the standardization from having
+dependencies included means that you get the same behavior wherever you
+run it.
+
+Containers decouple applications from underlying host infrastructure.
+This makes deployment easier in different cloud or OS environments.
+-->
+
+每个运行的容器都是可重复的；
+包含依赖环境在内的标准，意味着无论您在哪里运行它，您都会得到相同的行为。
+
+容器将应用程序从底层的主机设施中解耦。
+这使得在不同的云或 OS 环境中部署更加容易。

+## Container images
+A [container image](/docs/concepts/containers/images/) is a ready-to-run
+software package, containing everything needed to run an application:
+the code and any runtime it requires, application and system libraries,
+and default values for any essential settings.
+
+By design, a container is immutable: you cannot change the code of a
+container that is already running. If you have a containerized application
+and want to make changes, you need to build a new image that includes
+the change, then recreate the container to start from the updated image.
+-->
+
+## 容器镜像 {#container-images}
+[容器镜像](/zh/docs/concepts/containers/images/)是一个随时可以运行的软件包，
+包含运行应用程序所需的一切：代码和它需要的所有运行时、应用程序和系统库，以及一些基本设置的默认值。
+
+根据设计，容器是不可变的：你不能更改已经运行的容器的代码。
+如果有一个容器化的应用程序需要修改，则需要构建包含更改的新镜像，然后再基于新构建的镜像重新运行容器。
