Docker ubuntu apt-get更换国内源解决Dockerfile构建速度过慢

创建Dockerfile并且更新apt源

在Dockerfile中添加如下两句代码：

RUN  sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list
RUN  apt-get clean

更新apt源的Dockerfile如下：

FROM ubuntu:latest
MAINTAINER kk "kk@qq.com"
RUN  sed -i s@/archive.ubuntu.com/@/mirrors.aliyun.com/@g /etc/apt/sources.list
RUN  apt-get clean
RUN apt-get update
