MountedVolume Not Updating X11 Forwarding

docker

(Twgibbons) #1

Issue Type:

I am running docker an vm from which I need GUI display. I pass in X11 credentials through ssh -X. I then run a docker container mounting --volume="$HOME/.Xauthority:/root/.Xauthority:rw". I can then run a display within the container. But if I exit out of the vm and leave the container running, when I ssh back in the Xauthority file updates on the vm, but not on the container so then I get X11 authentication error within the container. This volume updates if I stop and restart the container, but that is not feasible for my application to be restarting the container constantly. If I manually update the xauth list in the container can get it running again, but why doesn’t the volume update in the container when it does on the host?
