Introduction

Docker Overview

Docker is an open-source application container engine. If the delivery and running environment is compared to sea transportation, the OS is like a freighter and each OS-based software is like a container, where users can flexibly assemble the running environment by using standard methods. The content of the container can be customized by users or made by professionals. In this way, a piece of software can be built by a series of standardized components, like Lego building blocks. Users only need to select a proper building block combination and name it on the top (the last standardized component is the user's app). This is the prototype of the Docker-based PaaS products.

Developers can package their applications and dependencies into a portable container and then publish them to any popular Linux machine. The containers use the sandbox mechanism, which eliminates interface between containers.
