Hello everyone,

I tried to run to ROS2 two nodes in different containers as described here: https://docs.ros.org/en/foxy/Guides/R... (I used foxy instead of eloquent). Everything works just fine.

Then I started two instances of vs code and opened the workspace in a remote container (based on the same image as above). In the first remote container I start the talker, in the second remote container I start the listener. Unfortunately they don't find each other. Does anyone have an idea what might be the solution?

Thanks a lot Jeremy

I found the solution of the problem. The issue is that Fast-DDS comes with SharedMemory transport by default which doesn't work in this case. A solution can be found here: https://answers.ros.org/question/3705....
