The First Book of Docker (Revised Edition)

This is the Chinese revised edition of The First Book of Docker, written by James Turnbull, former Vice President of Services and Support at Docker, and translated by Li Zhaohai, Liu Bin, and Ju Zhen. Docker is an open-source application container engine: developers can package an application and its dependencies into a portable container and then publish it to run on any mainstream Linux machine, gaining lightweight, reproducible runtime environments. The revised edition updates the content for Docker 1.9 and later, with the main thread guiding readers through the complete flow from installation, deployment, and management to scaling, covering the development life cycle from testing to production. The book starts with the basics of Docker and its core components (client and server, images, Registry, containers), then moves into practice: using Docker to set up test environments for new projects; integrating Docker into continuous integration workflows; using containers to build application services and platforms; operating programmatically through the Docker API; and orchestration and service discovery in multi-host scenarios. It also discusses where Docker is and is not suitable, helping readers judge when to use a containerized approach. The book is not long and contains many code examples, leaning toward hands-on practice; it works well as a first reference for introducing containerization within a team.
