Create a tiny virtual environment, called a container, that holds just your application and its dependencies. The Docker engine uses the host operating system to build and account for these containers. They are easy to install, manage, and remove. Applications running inside containers share resources, making their footprints small.About the BookDocker in Action teaches readers how to create, deploy, and manage applications hosted in Docker containers.
