Docker is rapidly changing the way organizations deploy software at scale. However, understanding how Linux containers fit into your workflow--and getting the integration details right--is not a trivial task. With the updated edition of this practical guide, you'll learn how to use Docker to package your applications with all of their dependencies and then test, ship, scale, and support your containers in production.

This edition includes significant updates to the examples and explanations that reflect the substantial changes that have occurred over the past couple of years. Sean Kane and Karl Matthias have added a complete chapter on Docker Compose, deeper coverage of Docker Swarm mode, introductions to both Kubernetes and AWS Fargate, examples on how to optimize your Docker images, and much more.

• Learn how Docker simplifies dependency management and deployment workflow for your applications
• Start working with Docker images, containers, and command line tools
• Use practical techniques to deploy and test Docker containers in production
• Debug containers by understanding their composition and internal processes
• Deploy production containers at scale inside your data center or cloud environment

• Explore advanced Docker topics, including deployment tools, networking, orchestration, security, and configuration

Docker正在迅速改变组织大规模部署软件的方式。然而，了解Linux容器如何融入你的工作流程--以及正确地整合细节--并不是一件简单的事情。通过这本实用指南的更新版，你将学会如何使用Docker来打包你的应用程序及其所有的依赖关系，然后在生产中测试、运送、扩展和支持你的容器。

本版包括对实例和解释的重大更新，反映了过去几年中发生的实质性变化。Sean Kane和Karl Matthias增加了关于Docker Compose的完整章节，深入介绍了Docker Swarm模式，介绍了Kubernetes和AWS Fargate，以及关于如何优化Docker镜像的例子，还有更多。
