This uses two containers - one running apt-cacher-ng, and one running rawdns. In fact, this gist is mostly based on the apt-cacher-ng hack documented the rawdns repo.

This includes a few quirks for OS X, which I'll make note of.

Edit ('create') /etc/rawdns.json to look like the rawdns.json in this gist.
Run a rawdns container: docker run -d --name rawdns -p 53:53/udp -v /var/run/docker.sock:/var/run/docker.sock -v /private/etc/rawdns.json:/etc/rawdns.json:ro tianon/rawdns rawdns /etc/rawdns.json. Note that this references /private/etc/rawdns.json; this is because on OS X, /etc is symlinked to /private/etc, and you can't mount a symlink.
Update your DNS resolver to use 127.0.0.1! Assuming OS X, this is in the Network preference pane, behind Advanced -> DNS.
dig dns.docker should now include SERVER: 127.0.0.1#53(127.0.0.1).

The Test

This test times how long it takes to run puppet apply to install a large amount of monitoring software on a Docker container using the Vagrant 1.6 Docker provisioner. It is a mixed test that measures network speed (downloading large packages and plugins,) disk performance, and CPU performance.
