    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # 阿里仓库,相对下载速度要快
# 也可以使用官网https://download.docker.com/linux/centos/docker-ce.repo 

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

#下载高版本rpm 下载速度有点慢，建议拷贝链接使用迅雷下载，在传rpm包到centos系统中
wget https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm  
sudo yum install containerd.io-1.2.6-3.3.el7.x86_64.rpm #安装containerd.io
#再次重新安装docker
sudo yum install docker-ce docker-ce-cli containerd.io

yum list podman-manpages  #查看 podman-manpages
yum remove podman-manpages.noarch  #卸载podman-manpages.noarch

#再次重新安装docker
sudo yum install docker-ce docker-ce-cli containerd.io

yum list docker-ce --showduplicates | sort -r  #查看版本
sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io #安装指定版本
