I made the docker image normally and then deploy those module images to ACR successfully. But IoT edge device can't get those image from Azure cloud. when I get the error logs from raspberry device as below.

I've already followed below guide and FAQ, but result is same.

  • Are you sure you have done this correctly? https://stackoverflow.com/a/53258408/1537195 It sounds a lot like your Edge device does not have the credentials to your private ACR – silent Jan 29 '19 at 14:46
  • Also leverage the Troubleshooting doc: https://learn.microsoft.com/en-us/azure/iot-edge/troubleshoot – asergaz Jan 29 '19 at 15:22
  • Hi! @silent Are you sure you have done this correctly? > I couldn't see the 'Set Modules' in the ACR service. But I've done to execute command for login docker with ACR ID,PW as below.
    `docker login -u -p `     – taeho kim Jan 30 '19 at 01:29
  • not in the ACR, the set modules is in the IoT Hub -> IoT Edge screen. It is where you defined which modules to run on your Edge device. – silent Jan 30 '19 at 08:00
  • I've done to `set Modules` as your desc. And then I executed `Build IoT Edge solution` menu for regeneration of `config/deployment.json` file at visual studio code after `.env` files editing. Also I did `create Deployment to Single Device`. But result is same on my side. I saw the logs as below after reboot. – taeho kim Jan 30 '19 at 08:34
