Ros_bridge not publishing ROS messages

I’ve followed the tutorial on Setting up a new Unity Project, but want to set up the a new catkin_ws independent of the provided docker space. I’m quite new to ROS so this might be obvious. I’ve tried to run roslaunch rosbridge_server rosbridge_tcp.launch bson_only_mode:=true And then press play in Unity. The console in Unity then reports that connection to ros bridge is established, and rostopic list confirms that the topics have been published. However, when opening up rviz to view the sensors, none of them receive any messages.

Is it possible to get access files in the docker container so that it is easier to set up a workspace outside of docker? Does anyone know how to solve this issue?

I found the easy way to solve this issue, but it only works on a linux host.

Add the --network host argument to the docker run command. You can also remove the --publish arguments to prevent the getting WARNING: Published ports are discarded when using host network mode.

Proof of fix

Run the docker image

docker run -it --rm \
--network host \
--name my_zerosim_vnc_docker \
zerodog/zerosim_ros_vnc:latest \
roslaunch zero_sim_ros basic_unity_editor.launch

@EdvardGrodem, thank you for your reply. After switching to a different version of rosbridge as mentioned above, all the topics are visible now. Thanks!
