Python 3 app running in docker-compose will not print using print('text', end='\r')

Would appreciate a suggestion for a workaround or fix:

Python 3.9 running in docker-compose 3.8 and using CMD [ "python3", "-u", "app.py" ]

print('text', end='\r', flush=True) will not print to terminal - want this printed.

print('text', flush=True) will print to terminal.

Yes, using both "python3", "-u" and flush=True is an overkill. 🤷‍♂️
