2、参考官方网站安装

1、https://wiki.centos.org/AdditionalResources/Repositories

OS requirements 操作环境准备

To install Docker CE, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested.

The centos-extras repository must be enabled. This repository is enabled by default, but if you have disabled it, you need to re-enable it.

The overlay2 storage driver is recommended.

 yum --enablerepo=extras install centos-release-scl

　　

2、https://docs.docker.com/install/linux/docker-ce/centos/

$ sudo yum install -y yum-utils

$ sudo yum-config-manager \

    --add-repo \

    https://docs.docker.com/v1.13/engine/installation/linux/repo_files/centos/docker.repo

$ sudo yum-config-manager --enable docker-testing

$ sudo yum makecache fast

$ sudo yum -y install docker-engine

　　最后一步直接安装稳定版本

或者也可以安装指定版本：

查看有哪些版本可以安装

$ yum list docker-engine.x86_64  --showduplicates |sort -r

docker-engine.x86_64  1.13.0-1.el7                               docker-main

docker-engine.x86_64  1.12.5-1.el7                               docker-main

docker-engine.x86_64  1.12.4-1.el7                               docker-main

docker-engine.x86_64  1.12.3-1.el7                               docker-main   

安装指定版本

$ sudo yum -y install docker-engine-<VERSION_STRING>
