CentOS7 Docker-ce 安装(阿里源)

CentOS7 Docker-ce 安装(阿里源)

1、docker所依赖的包环境

yum install -y yum-utils device-mapper-persistent-data lvm2

2、Docker-ce 阿里源镜像

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

也可以使用官方的，不过比较慢

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

3、更新一下yum软件包

 yum makecache fast

4、安装docke-ce

默认安装最新版

yum -y install docker-ce

也可以指定版本

yum -y install docker-ce-18.06.3.ce-3.el7 

查看其它版本，按上面一条命令执行对应版本，即可安装

yum list docker-ce.x86_64 --showduplicates

5、启动docker

systemctl start docker.service 

6、开机启动docker

systemctl enable docker.service

7、查看

docker version

必须保证docker客户端和服务器均启动

执行结果如下：
