Basic for Docker

Docker is an open platform for developers and system administrators to develop, ship and run distributed applications as containers. It has quickly become the platform of choice for container-based virtualisation with recent support in Amazon Elastic Beanstalk, Microsoft Azure and Google Cloud compute engine.

The two core components are Docker Engine and Docker Hub. Docker Engine is a portable, lightweight run-time and packaging tool, on top of process (container) management, provides layered image management based on the Advanced multi-layered Unification FileSystem (AUFS) allowing incremental updates of a container image.
