[ros-users] Givving ROS an Official DockerHub Image

Sun Feb 8 00:35:10 UTC 2015

I made a quick video showing gazebo and rviz running inside docker.
Check it out if your interested:

The video shows some flickering with unity,
but that's just a bug between SimpleScreenRecorder and nvidia's flip
setting, it never shows on my display.
