Docker is a set of the platform as a service (PaaS) products that use OS-level virtualisation to deliver software in packages called containers.[6] Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and are thus more lightweight than virtual machines.
