Install Docker container under Linux

1. Introduction

Docker is an open source commercial product with two versions: Community Edition (Community Edition, abbreviated as CE) and Enterprise Edition (Enterprise Edition, abbreviated as EE). The enterprise version includes some paid services, which are generally not used by individual developers. The following introductions are all for the community edition.
For the installation of Docker CE, please refer to the official documentation. Here we take CentOS as an example:
Docker requires the kernel version of the CentOS system to be higher than 3.10, and the linux kernel version check command: uname -r

2. Installation
