It is a simple script to display IP addresses of each running container.
Copy it somewhere (for ex /usr/bin/dps), and launch some containers (here a ping to google.com)
zoobab@sabayon /home/zoobab/soft/docker-ps-showips [22]$ sudo docker run -d debian:wheezy ping google.com
f7d36f2b8e850c17aa3eef7b8e72e292d40dac72de335223259a5c7fb32bf226
zoobab@sabayon /home/zoobab/soft/docker-ps-showips [23]$ sudo docker run -d debian:wheezy ping google.com
a32b4e7ebf11d211252e7eab1e1105363d10bb39e6dd6dab41451ba094927a5a
Then run dps (you might need sudo or not):
zoobab@sabayon /home/zoobab [6]$ sudo dps
