自建虚拟机，但是连接不上网络，只能通过下载rpm包进行安装docker
环境：CentOS 7.3.1611 x64
rpm镜像下载地址用的阿里的
https://mirrors.aliyun.com/docker-ce/linux/centos/7/
在这里能找到想要的docker相关的所有包
我这里只下载了三个包。分别是
docker-ce-selinux-17.03.1.ce-0.1.rc1.el7.centos.noarch.rpm
docker-ce-17.03.1.ce-0.1.rc1.el7.centos.x86_64.rpm
containerd.io-1.2.0-1.0.beta.0.el7.x86_64.rpm将这三个包按照顺序分别安装即可，顺序的话，安装的时候会提示，如果顺序错了会提示有依赖包
rpm -ivh containerd.io-1.2.0-1.0.beta.0.el7.x86_64.rpm
rpm -ivh docker-ce-selinux-17.03.1.ce-0.1.rc1.el7.centos.noarch.rpm
rpm -ivh docker-ce-17.03.1.ce-0.1.rc1.el7.centos.x86_64.rpm 完成安装后，开启服务，查看是否安装成功
