I have created a docker image for opencv and facial reckognition to simplify the setup process.
But the recognize.py script needs X Server to show the image result. Here is what I have done so far:
sudo docker run -t -d --name opencv opencv:latest
sudo docker exec -it opencv bash /extract-embeddings.sh
sudo docker exec -it opencv bash /train-model.sh
All is fine so far. The last step is the actual comparison that displays the result in an image.
sudo docker exec -it opencv bash /face-recognition.sh
It gives the output:
[INFO] loading face detector...
[INFO] loading face recognizer...
No protocol specified
: cannot connect to X server :0
I have tried running the container with the following command:
sudo docker run -t -d --name opencv -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix opencv:latest
But it doesn't help.
Try running this,
xhost +
sudo docker run --rm -ti --net=host --ipc=host -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix --env="QT_X11_NO_MITSHM=1" <image_name> <arguments>
Other might face issue regarding the image not getting rendered on screen or getting a blank screen with no image, for them add --env="_X11_NO_MITSHM=1"
to the above script while running the docker image. It will solve the problem.
For further information, I would recommend you guys check out the below references.

It looks like the xauth is the issue for viewing of the image. The details are at Can you run GUI applications in a Docker container?
