I am trying to use CounterFit in Dev Container as part of IoT-For-Beginners course. So idea is to run all course using virtual hardware but not directly on local PC but rather in docker container.
from counterfit_connection import CounterFitConnection
CounterFitConnection.init('127.0.0.1', 5000)
print('Hello World!')
