Bind the docker daemon's socket to the builder so it can run an nbuild container. Note that it needs two volumes: one for the manifests and the built packages. It also needs to be a tty and an access to the internet.
docker run -v /var/run/docker.sock:/var/run/docker.sock -v nbuild_manifests:/app/manifests/ -v nbuild_out:/app/out/ -t tmp/builder
