Docker从1.13版本之后采用时间线的方式作为版本号，分为社区版CE和企业版EE。
社区版是免费提供给个人开发者和小型团体使用的，企业版会提供额外的收费服务，比如经过官方测试认证过的基础设施、容器、插件等。
社区版按照stable和edge两种方式发布，每个季度更新stable版本，如18.03，18.06；每个月份更新edge版本，如18.06，18.07。
Docker安装
- Docker 要求 CentOS 系统的内核版本高于 3.10 ，查看本页面的前提条件来验证你的CentOS 版本是否支持 Docker 。
通过 uname -r 命令查看你当前的内核版本
[root@ecs-a30e-0002 ~]# uname -r
3.10.0-693.11.1.el7.x86_64- 使用 root 权限登录 Centos。确保 yum 包更新到最新。
[root@ecs-a30e-0002 ~]# yum update- 卸载旧版本(如果安装过旧版本的话)
[root@ecs-a30e-0002 ~]# yum remove docker docker-common docker-selinux docker-engine- 安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的
[root@ecs-a30e-0002 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2- 设置docker的yum源
[root@ecs-a30e-0002 ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
Loaded plugins: fastestmirror
adding repo from: https://download.docker.com/linux/centos/docker-ce.repo
grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo
repo saved to /etc/yum.repos.d/docker-ce.repo
- 可以查看所有仓库中所有docker版本，并选择特定版本安装
[root@ecs-a30e-0002 ~]# yum list docker-ce --showduplicates | sort -r
