UPDATE 2:
I have to abandon this effort for now (trying to run TUI and OpenTap test steps on a container) unless a magical fix appears. I was able to get the ContainerExpert GUI running inside the container, but it (the GUI) would just sit and spin with a splash screen of “Initializing…”. The ConnExpert also spew out a brief session setting string that implied that the session was using the correct IP (which was the IP of my Mac Host).
I’ve run out of ideas to try. FYI here is a screen capture of the ContainerExpert running in an Xterm (the GUI is actually behind the two command terminals):
UPDATE 11-18 Problem fixed, see the thread: Installing KeySight IO Lib on OpenTap Ubuntu Container for details
