Docker in Action

The idea behind Docker, a free an open source program, is simple. Create a tiny virtual environment, called a container, for an application that includes only its particular set of dependencies. The Docker engine accounts for, manages, and builds these containers through functionality provided by the host operating system. Software running inside containers share the Linux OS and other resources, making their footprints radically smaller, and the containerized applications easy to install, manage, and remove. Applications can be packaged without worrying about environment-specific deployment concerns, and the operations team gets cleaner, more efficient systems across the board.

Readers need a working knowledge of installing and running software on the Linux OS. No prior experience with Docker or other virtualization technologies is required.

ABOUT THE TECHNOLOGY

Docker provides software logistics. It uses "container" abstraction to hide complex tooling for packaging software, and running software in virtualized environments without overhead of a full virtual machine. Docker and the container abstraction are driving a change in the way people write, test, deploy, and distribute software.
