Minimal steps to reproduce

Deploy amd64 solution on a Windows 10 simulated IoT Edge Device.

Any log messages given by the failure

The camera-capture module will crash on runtime with no logging. All the other modules run with logging available.

PS C:\WINDOWS\system32> iotedge logs camera-capture
PS C:\WINDOWS\system32>

PS C:\WINDOWS\system32> iotedge list

Expected/desired behavior

A running camera-capture container with logging on a windows 10 device with docker installed (followed the instructions on Windows).

OS and Version?

Windows 10

Versions

Docker Version 17.12.0-ce-win47 (15139) VS Code version 1.27 PowerShell version 5.1.16299.611

Mention any other details that might be useful

Can’t provide detailed info because there is no logging available. Docker engine is set to Linux containers.

Thanks! We’ll be in touch soon.

Correct, this is a limitation of Docker for Windows. You cant use read streams from a USB device. Reading a stream from a USB device will only work on a Linux host that has direct access to the USB camera (e.g. not the MobyLinuxVM set up by Docker for Windows) with Linux containers.

Also correct that the test-amd64 does not run the python script by default by just open a bash prompt. This is mostly useful to debug your own custom version of this container.

Ok then I understand. Nowhere does it say that Live webcam feed will not work for the Windows 10 PC option.
