Docker版本要求 CentOs 系统的内核版本高于 3.10，可通过如下指令查看版本

uname -r

卸载docker，并更新yum

sudo yum remove docker docker-common container-selinux docker-selinux docker-engine
sudo yum remove -y docker-*
sudo yum update

查看仓库版本号，并指定版本安装

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sudo yum makecache

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

yum install docker-ce-3:20.10.0-3.el7.x86_64
