To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:


    dockerd-rootless-setuptool.sh install





解决办法：

1.查看系统版本信息cat /etc/redhat-release


2.从开源镜像站 mirrors.163.com 找到系统对应密钥
3.导入密钥
rpm --import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
4.启动Docker

systemctl start docker
systemctl status docker
