解决办法

换docker源

先删掉，之后再安装依赖:

sudo yum remove docker docker-common docker-selinux docker-engine
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

docker.repo文件

wget -O /etc/yum.repos.d/docker-ce.repo https://mirrors.huaweicloud.com/docker-ce/linux/centos/docker-ce.repo

软件仓库地址替换为：

sudo sed -i 's+download.docker.com+mirrors.huaweicloud.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo

更新索引文件并安装

sudo yum makecache fast
