Centos7.9 安装 Docker
由于docker被封，直接使用docker官方的教程安装会被墙，所以使用阿里云的源进行安装
参考文档：https://help.aliyun.com/zh/ecs/use-cases/install-and-use-docker-on-a-linux-ecs-instance
安装Docker
- 运行以下命令，下载docker-ce的yum源。
sudo wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
- 运行以下命令，安装Docker。
sudo yum -y install docker-ce
遇到的问题
1. 依赖问题 container-selinux >= 2:2.74
[root@VMS-WL001131 ~]#y yum -y install docker-ce

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
下载安装container-selinux
https://linuxsoft.cern.ch/cern/centos/7/extras/x86_64/repoview/container-selinux.html
鼠标右键超链接，复制需要下载的rpm地址
wget https://linuxsoft.cern.ch/cern/centos/7/extras/x86_64/Packages/container-selinux-2.107-3.el7.noarch.rpm
rpm -ivh container-selinux-2.107-3.el7.noarch.rpm
