Problems launching rocon chatter concert inside of a Docker image
I am trying to get a simple rocon concert working inside of a Docker instance with my limited knowledge of rocon and avahi.
I started from this Docker image which provides the base ROS installation and got rocon_tutorials from the the apt repos there. I verified I can successfully run basic ROS nodes and configurations. Unfortunately, when trying to run the rocon chatter concert I get some issues which I am having trouble getting past.
The most relevant symptom is that all consoles spawned by the rocon launch show the following error:
[ERROR] [1424808531.546619171]: Zeroconf: failed to create an avahi client.
after which everything else fails.
I have tried several things including running avahi manually inside the docker container, making sure to start the docker container in privileged mode, etc.
Any guidance on how to further tackle the problem, or any general hints on getting the environment right for rocon would be greatly appreciated
