Я создал контейнер, содержащий этот образец Python script https://github.com/Azure/azure-iot-sdk-python-preview/blob/master/azure-iot-device/samples/advanced-edge-scenarios/send_message.py.

Мой Dockerfile выглядит следующим образом 

FROM arm32v7/python:3

RUN pip install azure-iot-device
ADD testscript.py /

CMD [ "python", "./testscript.py" ]

Я создаю Контейнер использует Docker задач в конвейере в Azure DevOps, и я использую Raspberry с Raspbian Stretch в качестве сервера сборки.

Я установил Azure IoT Edge Runtime на другой Raspberry. При развертывании контейнера с IoT Hub на Raspberry статус будет закрыт, а в журналах будет показано следующее:
