最近在openeuler上安装docker，按常规方法安装报以下错误，经过排查已解决，现记录一下解决办法。

首先下载docker官方源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
把docker-ce-repo文件里的变量替换为7
sed -i 's/$releasever/7/g' docker-ce.repo
把docker-ce.repo文件里的官方下载地址换为阿里云的。
sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
如果是国产如飞腾或麒麟CPU，它们是arm架构的，需要下载阿里云arm的yum源。
wget http://mirrors.aliyun.com/repo/Centos-altarch-7.repo -O /etc/yum.repos.d/CentOS-Base.repo
修改阿里云的CentOS-Base.repo
sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo
然后再安装docker
yum clean all yum install -y docker-ce
