Azure IoT Edge Custom Module IoT Create Options - Host Config

Dominik Koller 21

I tried to use the DeviceCgroupRules property within the HostConfig of the section of the create options of a custom IoT Edge module and after setting the property the desired version of the create options shows the HostConfig with the DeviceCgroupRules but it is never reported back. In general, it looks like if this property is not supported because just an empty HostConfig object is reported back.

Create Options used:

{
"HostConfig": {
"DeviceCgroupRules": [
"c 188:* rmw"
]
}
}

Hello @Dominik Koller , `Thanks for reaching out to us!
Could you please let us know the Device information, like Model, Architecture, and any documentation have you followed on this topic. Have you verified this setting on the device side?

Please refer to How to configure container create options for IoT Edge modules.
Have you referred to Docker container create options ?

I was following the documents you have linked and I also verified the setting on the device side using docker inspect, but there the setting is then also just null instead of the value I wanted to set. In the meantime, I also tried to use a deployment manifest locally and added the same setting as on the IoT Hub and run it with the simulator but the same problem -> if I check it with docker inspect the property is just null. Currently, I was testing it on my development machine which is running Ubuntu 20.04 LTS, Dell, AMD64.

Hello @Dominik Koller , are you able to set any other HostConfig property for your module? like PortBindings, Memory, DNS, CPUPeriod...

Yes, we tested it back in August and it worked with the 1.0.10 version, so the problem is solved.
