This container enables you to build a local mirror for Debian, Ubuntu and Raspbian.
Just run make - that will build the abhas/apt-mirror Docker image.
First, create a directory that will be used to store your mirror contents. And then pass that to the Docker run command line as follows:
mkdir /tmp/apt-mirror
docker run -ti --rm --name apt-mirror -v /tmp/apt-mirror:/var/spool/apt-mirror abhas/apt-mirror
