What makes you think it's not working/can you show exactly what you've configured? Post both your code as text in a preformatted text block, and a screenshot of how you've got things configured.
You would need to open a shell into the container. docker exec IIRC. (I haven't been using docker much, lately.)
Consider using a logger instead of using print.
Also, inheritable projects do not actually run anything. Only leaf projects are actually runnable. (You should never define gateway or Vision client events in inheritable projects--unless you want madness and confusion.)
