执行如下命令
yum erase podman buildah
配置阿里云地址
$ sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
安装 Docker Engine-Community
安装最新版本的 Docker Engine-Community 和 containerd，或者转到下一步安装特定版本：
$ sudo yum install docker-ce docker-ce-cli containerd.io
$ sudo systemctl start docker
卸载 docker
删除安装包：
yum remove docker-ce
删除镜像、容器、配置文件等内容：
rm -rf /var/lib/docker
