Searching for nodes in a single container fails. Run demo_nodes_cpp as a talker and listener, then ros2 node list shows no node.

It fails on both Intel and M1 Macs. This happens on both foxy and humble. Creating a container on Ubuntu 22.04 amd64 with the same settings does not cause the problem.

When running in Docker on an M1 Mac, node discovery fails.

If you do it with rmw_fastrtps_cpp, the node discovery fails without any error message.

$ ros2 node list

If you set RMW as rmw_cycloid_cpp, you will get the following error message.
