Summary & Highlights: Understanding the Benefits of Containers概要与重点：理解容器的优势

Congratulations! You have completed this first module. 
恭喜！您已完成本模块。

At this point, you know: 
此时，您已了解：

• A container is a unit of software that encapsulates everything needed to build, ship, and run applications.  
  容器是一个封装了构建、部署和运行应用程序所需所有内容的软件单元。
• Containers lower deployment time and costs, improve utilization, automate processes, and support next-gen applications (microservices). Major container vendors include Docker, Podman, LXC, and Vagrant. 
  容器可缩短部署时间、降低成本、提高利用率、自动化流程，并支持下一代应用程序（微服务）。主要的容器供应商包括 Docker、Podman、LXC 和 Vagrant。
• Docker is an open platform used for developing, shipping, and running applications as containers. 
  Docker 是一个用于开发、交付和运行容器化应用的开放平台。
• Docker containers are not a good fit for applications based on monolithic architecture or applications that require high performance or security. 
  Docker 容器不适合基于单体架构的应用程序，或者需要高性能或安全性的应用程序。
• Docker architecture consists of the Docker client, the Docker host, and the container registry. 
  Docker 架构由 Docker 客户端、Docker 主机和容器注册中心组成。
• The Docker host contains objects such as the Dockerfiles, images, containers, networks, storage volumes, and other objects, such as plugins and add-ons. 
  Docker 主机包含 Dockerfile、镜像、容器、网络、存储卷等对象，以及其他对象，如插件和附加组件。
• Docker uses networks to isolate container communications. 
  Docker 使用网络来隔离容器通信。
• Docker uses volumes and binds mounts to persist data even after a container stops running. 
  Docker 使用卷和绑定挂载来持久化数据，即使容器停止运行也是如此。
• Plugins, such as storage plugins, provide the ability to connect to external storage platforms. 
  插件，例如存储插件，提供了连接到外部存储平台的能力。
