docker-nss

A libnss plugin for finding Docker containers

This is still a work in progress!

Installing

git clone https://github.com/danni/docker-nss.git
cd docker-nss
sudo make all install
sudo sed -i -re 's/^(hosts: .*$)/\1 docker/' /etc/nsswitch.conf

or edit /etc/nsswitch.conf:

hosts:      files dns mdns4_minimal myhostname docker
                                               ^

Testing

LD_LIBRARY_PATH=`pwd` PATH=`pwd`/mocker:$PATH ./test

LD_LIBRARY_PATH=`pwd` getent hosts badger.docker
LD_LIBRARY_PATH=`pwd` getent hosts 10.0.0.0

ToDo

• Look up containers by image name/ID (not just container ID)
• Look up container names for IP addresses
