国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

中国移动在为用户安装宽带时，总会好心地“赠送”一个光猫(调制解调器)。这看似是个不错的促销手段，但通常情况下，这个“赠品”会给用户带来许多麻烦。
赠送的“光猫”安装了许多不必要的功能。光猫的本职工作是进行光电转换，然而中国移动的“光猫”不仅承担着光电转换的任务，还同时进行拨号上网、路由、地址转换(NAT)、端口映射、文件服务器(FTP)等等额外的功能。这些功能让本就廉价而算力低下的光猫运行缓慢，不堪重负。最可气的是，中国移动为了节约维护成本，将光猫的绝大多数设置项锁定，防止用户修改。为了重新“拥有”光猫，我决定夺回对光猫的控制权。
