docker容器中ubuntu软件源更换

1. 动机

docker公开的ubuntu镜像大多数都是使用ubuntu官方的镜像源，容易下载失败或者网速过慢

2. 替换

比如，如下的Dockerfile

 1 FROM nvidia/opengl:base-ubuntu18.04
 2 
 3 ARG DEBIAN_FRONTEND=noninteractive
 4 
 5 RUN apt -y update && \
 6   cp /etc/apt/sources.list /etc/apt/sources.list.ori && \
 7   sed -i s@/archive.ubuntu.com/@/mirrors.ustc.edu.cn/@g /etc/apt/sources.list && \
 8   sed -i s@/security.ubuntu.com/@/mirrors.ustc.edu.cn/@g /etc/apt/sources.list && \
 9   apt clean && apt -y update && apt -y install \
10   freeglut3-dev clang-format build-essential cmake \
11   xorg-dev libglu1-mesa-dev
12 
13 # Clean up APT when done.
14 RUN apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*

通过第7、8两行，将软件源更换为ustc。

运行测试：sudo docker build -t opengl-tutorial .
