+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。

+## 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。

+<!--
+Kubernetes networking addresses four concerns:
+- Containers within a Pod use networking to communicate via loopback.
+- Cluster networking provides communication between different Pods.
+- The Service resource lets you expose an application running in Pods to be reachable from outside your cluster.
+- You can also use Services to publish services only for consumption inside your cluster.
+-->
+
+Kubernetes 网络解决四方面的问题：
+- 一个 Pod 中的容器之间通过本地回路（loopback）通信。
+- 集群网络在不同 pod 之间提供通信。
+- Service 资源允许你对外暴露 Pods 中运行的应用程序，以支持来自于集群外部的访问。
+- 可以使用 Services 来发布仅供集群内部使用的服务。
