X11 Authentication Error when run as a Docker container
I'm trying to run an application from a Docker container which is supposed to open a GUI widow (a video stream in my case). The Docker container is run on a Raspberry Pi and I SSH into the Pi from my Mac and then I issue the Docker run command. I have one problem here:
When I run the whole thing as follows, it works flawlessly:
- I run the command as:
docker run -it --net=host --device=/dev/vcsm --device=/dev/vchiq -e
DISPLAY -v /tmp/.X11-unix joesan/motion_detector bash
From the bash, that opens up after issuing the Docker run command, I install xauth
root@cctv:/raspi_motion_detection/project# apt-get install xauth
I then add the Xauth cookie using Xauth add
I then run my Python program which shows the GUI window with the video stream
So far so good. But, every time I don't want to be doing these steps all over again. So I wrote a small script to do this as below:
HOST=cctv
DISPLAY_NUMBER=$(echo $DISPLAY | cut -d. -f1 | cut -d: -f2)
echo $DISPLAY_NUMBER
# Extract auth cookie
AUTH_COOKIE=$(xauth list | grep "^$(hostname)/unix:${DISPLAY_NUMBER} " | awk '{print $3}')
# Add the xauth cookie to xauth
xauth add ${HOHOSTSTNAME}/unix:${DISPLAY_NUMBER} MIT-MAGIC-COOKIE-1 ${AUTH_COOKIE}
# Launch the container
docker run -it --net=host --device=/dev/vcsm --device=/dev/vchiq -e DISPLAY -v /tmp/.X11-unix joesan/motion_detector
But this time it fails with the error:
X11 connection rejected because of wrong authentication.
Unable to init server: Could not connect: Connection refused
I then tried to run the above script as a sudo user and I get the following:
xauth: file /root/.Xauthority does not exist
xauth: (argv):1: bad "add" command line
X11 connection rejected because of wrong authentication.
Unable to init server: Could not connect: Connection refused
Is there anything that I'm missing? Please help!
