I need to run scripts when the can0 device is plugged in or removed. The device is a peak-can and works fine in BalenaOS.
I have set
In docker-compose.yml, I have set ENV UDEV=on in the Dockerfile.
My rules file looks like this:
ACTION==“add”, KERNEL==“can[0-1]", SUBSYSTEM==“net”, RUN+="/root/can_up.sh"
ACTION==“remove”, KERNEL=="can[0-1]”, SUBSYSTEM==“net”, RUN+="/root/can_down.sh"
The rules works perfectly in my Arch desktop system.
I’ve verified that all the files are in their correct places in the container.
When I run udevadm monitor on the host OS terminal I can see the can0 device being detected on plug i and out events. In the container nothing happens. All the docs I have read tells me that the above is all that is necessary to get device events communicated to the container - but this does not work.
How do I get can device plug-in events to my container ?
