Installing Docker under Linux

After March 1 in 2017, the Docker version was named for the CE (Community Edition, Community Edition) version and the EE (Enterprise Edition, Corporate Edition) version. We use the CE version is enough.
The basic operating system can be installed.
I highly recommend that you install under Linux, not under Windows, because the Linux version of Docker is for enterprise production.

1.CentOS
