Map Webcam into Docker / Docker looses device

[Presswerk65]

Hi everyone
I have installed the DVB-Driver-Package for getting Webcam/Video support. I can access the devices over the static link (created by v4l)

/dev/v4l/by-id/usb-somenameandid-video-index0

but unfortunately, Docker looses the connection to this devices every few hours.

Then I have to execute '''sudo udevadm control --reload-rules && sudo udevadm trigger''' and restart the container.

So it runs for a few hours until have to do it again.

The webcams are connected over usb hubs (2 cams on 2 hubs into 4 containers)

 

Any hints what I could do to prevent this behavior?

 

Thanks!
