Udev Output missing in Container

Hi Guys,

I have almost completed my "Ripper" container, that automatically will rip CDs/DVDs and BluRay disks when inserted.

The ripping itself works (tested with a dvd and cd).

The only thing missing to complete the container is proper UDEV Label-detection. For some reason docker containers are unable to get verbose udevadm output.

Here is the (required) output when using UNRAID's udevadm:

root@unraid:~# udevadm info -q env -n /dev/sr0

Within my container it only spits out:

root@fc211ad90a36:~# udevadm info -q env -n /dev/sr0

DEVNAME=/dev/sr0

DEVPATH=/devices/pci0000:00/0000:00:1c.6/0000:05:00.0/ata8/host8/target8:0:0/8:0:0:0/block/sr0

DEVTYPE=disk

MAJOR=11

MINOR=0

SUBSYSTEM=block

Any Idea how to get the verbose Information in my container? If udev is unable to do so: is there alternative software that can detect dvd/cd/bd disk types in /dev/srX?

Any advice is greatly appreciated in the quest for more complete automation!
