awesome 
yes for troubleshoot i basically went through the checklist of things you have to set. A whole back and forth making sure you didn’t miss a step or did something incorrectly.
To make sure the jailmaker stuff was correct, i enter jlmkr shell docker
then tested if i could detect the nvidia graphics card. These were some of the commands i used to confirm i could interact with the nvidia graphics card from within the docker jail
if that worked, then i moved onto the other steps.
so glad you figured that out
