When checking if iot edge is running I get the following error:

× container engine is installed and functional - Error
Could not communicate with container engine at unix:///var/run/docker.sock.
Please check your moby-engine installation and ensure the service is running.

Can this be related to a missing kernel module?
e.g. with CONFIG_BRIDGE_VLAN_FILTERING: missing ???

Maybe someone can give me a hint here.

Thanks a lot!

Hello,

I have the same problem. Does anybody has a solution for this?

BR Daniel

Were you able to solve this problem? Does Microsoft Azure IoT Runtime works now?

I not sure how this is now but in the past, the problem was, that a Revolution PI has preinstalled an Apache who is listening on 443. But we use 443 for the communication of our internal services like $edgeHub. Based on this the OS von Kunbus is not compatible with IoT Edge. You can buy the same HW from Cloudrail. In that case, the HW comes from Kunbus and the OS comes from Cloudrail. This OS is compatible. But you can stop Apache, and I think then it will work.

Depending also, what kind of HW you use, you maybe must free also some space. Attached, what I have installed and what kind of services are running on the RevPI.
BTW: the "iot-ssh-client.service" is devices streams. You maybe not needed.

In case someone finds this and has the same problem: I made a more detailed description of how I managed to install Azure IoT Edge and provision my device using the built-in TPM of my Revolution Pi Flat with Azure DPS here.

Hi,

we're currently replicating the issue.

The topic geebinge pointed out is correct.

See if you need IoT EdgeHub listen on port 443. (check here https://docs.microsoft.com/de-de/azure/ ... tion-rules)
By default Apache2 (Webserver for RevPi’s Admin Interface via HTTPS) is listening on 443. You can to deactivate it or change the port.

Deactivation:

Edit ports.conf Comment out the parts for port 443 like this
Save by typing CTRL + x

Restart the apache web server to apply the changed conf file:
