Docker CentOS installation
Docker version
Docker uses the timeline as the version number after version 1.13, and is divided into community version CE and enterprise version EE.
The Docker Community Edition is free for individual developers and small groups to use, and the Enterprise Edition will provide additional fee-based services, such as infrastructure, containers, plug-ins, etc. that have passed official testing and certification.
The Docker community version is released in two ways: stable and edge. The stable version is updated every quarter, such as 17.06 and 17.09; the edge version is updated every month, such as 17.09 and 17.10.

Docker Windows installation instructions
Docker released the official version of Docker for Windows, so you can run Docker containers under Windows. To run Docker under Windows, the following prerequisites are required:
64-bit Windows 10 Pro, Enterprise, or Education editions (Build 10586 and above, need to install 1511 November update).
Enable Hyper-V in the system. If not enabled, Docker for Windows will automatically enable Hyper-V during the installation process (this process requires a system restart). However, if you are not using Windows 10, it does not matter, you can use Docker ToolBox as an alternative.
