The document discusses Docker, a containerization platform. It begins with an overview of environment issues, virtualization history and containers like LXC. It then covers Docker in depth, highlighting its features like copy-on-write filesystems, image management and easy sharing. Docker is compared favorably to virtual machines for its speed, small size and efficient resource use. Instructions are provided for installing Docker and using basic commands. Finally, related tools like Docker Machine, Compose and Swarm are listed along with additional resources.
