Docker DNS is a python application you can use to
identify your containers by hostname or name.

You can run it with behind dnsmasq using the instructions

#sudo twistd dockerdns -u http://docker-server:5000 -p 53
# host mycontainer.docker # by container-name or hostname
172.17.0.12
# host mymage.*.docker # all container from a given image
172.17.0.12
172.17.0.13

Using twisted conch, I added sftp functionalities too, so you can access your container volumes directly.

#sftp -P10022 mycontainer@docker-server
sftp$ ls /
shared_volume1
shared_volume2
