centos7安装docker 并设置镜像仓库

先更新

yum -y update

如果有安装过先卸载旧版

yum remove docker  docker-common docker-selinux docker-engine

添加仓库

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://download.docker.com/linux/centos/docker-ce.repo
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

查看可用版本

yum list docker-ce --showduplicates | sort -r

安装，也可以指定版本

yum -y install docker-ce

启动

systemctl start docker

开机启动

systemctl enable docker

查看安装信息

docker info

编辑 /etc/docker/daemon.json添加仓库地址
