docker 安装
1. centos 安装 docker
yum-utils提供了yum-config-manager 效用，并device-mapper-persistent-data和lvm2由需要 devicemapper存储驱动程序
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
可选：启用边缘和测试存储库。这些存储库包含在docker.repo上面的文件中，但默认情况下处于禁用状态。您可以将它们与稳定的存储库一起启用。
sudo yum-config-manager --enable docker-ce-edge
sudo yum-config-manager --enable docker-ce-test
禁用
$ sudo yum-config-manager --disable docker-ce-edge
按版本号排序结果
$ yum list docker-ce --showduplicates | sort -r
$ sudo yum -y install docker-ce
$ sudo systemctl start docke
$ sudo docker run hello-world
卸载Docker包：
$ sudo yum remove docker-ce
不会自动删除主机上的图像，容器，卷或自定义配置文件。删除所有图像，容器和卷：
$ sudo rm -rf /var/lib/docker
