服务端创建Docker镜像并启动容器
创建 Dockerfile 文件，内容如下：
FROM ubuntu
VOLUME ["/var/cache/apt-cacher-ng"]
RUN sed -i "s@http://.*archive.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list && sed -i "s@http://.*security.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list
RUN apt-get update ; apt-get install -yq apt-cacher-ng
RUN echo "PassThroughPattern: ^(.*):443$" >> /etc/apt-cacher-ng/acng.conf
EXPOSE 3142
CMD chmod 777 /var/cache/apt-cacher-ng ; /etc/init.d/apt-cacher-ng start ; tail -f /var/log/apt-cacher-ng/apt-cacher.log
构建镜像：
docker build -t dt_apt_cacher_ng .
创建容器并启动
docker run -d -p 3142:3142 --name dt_apt_cacher_ng dt_apt_cacher_ng
查看日志
docker logs -f dt_apt_cacher_ng
客户端配置代理
EITHER: Configure APT to use a HTTP proxy by specifying it in apt.conf or related configuration files, see apt.conf manual page for details. Server and Port need to match the values used to visit this page. For example, edit /etc/apt/apt.conf (or create a new file called like /etc/apt/apt.conf.d/00aptproxy) and add the line:
Acquire::http::Proxy "http://172.17.0.2:3142";
配置apt代理规则，http请求走代理，https请求不走代理
echo 'Acquire::http::Proxy "http://10.10.140.105:3142";' > /etc/apt/apt.conf.d/00aptproxy
# vim /etc/apt/apt.conf.d/00aptproxy
Acquire::http::Proxy "http://10.10.140.105:3142";
Acquire::https::Proxy "false";
Dockerfile中使用代理
FROM ubuntu
RUN echo 'Acquire::http::Proxy "http://10.10.140.105:3142";
Acquire::https::Proxy "false";' >> /etc/apt/apt.conf.d/00aptproxy
RUN RUN apt-get update ; apt-get install vim git
服务端支持代理https请求
https://wiki.debian.org/AptCacherNg
apt-cacher-ng显然无法为HTTPS存储库提供服务。上游有很多解决方案，但我发现最简单的解决方案是直接在代理上隧道HTTPS连接，方法是将其放入/etc/apt-cacher-ng/acng.conf：
PassThroughPattern: ^(.*):443$
据我所知，这是避免对HTTPS存储库的客户端进行特殊配置的唯一方法。缺点是HTTPS内容没有缓存。
