Я пытаюсь развернуть вложенную структуру Azure IoT Edge на двух raspberry pi: s, используя следующую документацию: https://docs.microsoft.com/en-gb/azure/iot-edge/tutorial-nested-iot-edge?view=iotedge-2020-11&tabs=azure-portal.
Устройство верхнего уровня работает правильно, модули загружаются и устанавливается соединение с Центром Интернета вещей.
Единственная проблема, которую я сейчас вижу на устройстве верхнего уровня, - это журналы IoTEdgeApiProxy:
pi@top-layer-device:~ $ iotedge logs IoTEdgeAPIProxy
[2021-01-20T13:33:58Z WARN mqtt3::client::connect] could not connect to server: Connection refused (os error 111)
[2021-01-20T13:33:58Z WARN mqtt3::client::connect] could not connect to server: Connection refused (os error 111)
[2021-01-20T13:34:06Z WARN mqtt3::client::connect] could not connect to server: Connection refused (os error 111)
[2021-01-20T13:34:09Z WARN mqtt3::client::connect] could not connect to server: Connection refused (os error 111)
Устройство нижнего уровня вытащило edgeAgent из родительского устройства, но не потянет другие модули, указанные в развертывании:
pi@middle-layer-device:~ $ iotedge list
NAME STATUS DESCRIPTION CONFIG
edgeAgent running Up a week top-layer-device:8000/azureiotedge-agent:1.2.0-rc2
Config.yaml настроен с именем родительского хоста в качестве устройства верхнего уровня. В etc / hosts я настроил устройство верхнего уровня на IP устройства верхнего уровня в сети.
Вывод edgeAgent устройства, который продолжает повторять:
