/dev/sgX keeps changing

[tbrannam]

I've notice that when my USB Optical drive is re-plugged, that the assigned SCSI device path is not fixed. Initially it might be /dev/sg2, but later it might be /dev/sg4. I am curious if there are techniques to ensure a fixed assignment that I can use for my Docker configuration. My temp fix is to run the container in Privileged, but want to remove this once I have a proper solution.

Just pass sg1 through sg6

I had tried that but was getting errors sometimes that one of the sg devices isn't present. Which might be a clue to why it keeps changing on a re-plug. Portainer at least would not start the container without being able to map all the devices. Perhaps this is a Portainer specific issue with the devices vs a stock docker environment.
