Docker: Could not connect to any X display

Although the container should have the needed privileges to connect to the display, I got this error each time:

docker exec -it my_container

/# rqt

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
No protocol specified
QXcbConnection: Could not connect to display :1
Could not connect to any X display.

The following command has been used to run the container:

sudo docker run -itd --restart unless-stopped --name my_container --privileged --net=host --gpus all \
    --env="NVIDIA_DRIVER_CAPABILITIES=all" \
    --env="DISPLAY=$DISPLAY" \
    --env="QT_X11_NO_MITSHM=1" \
    --volume="/tmp/.X11-unix:/tmp/.X11-unix:rw" \
    my_image:v1.1

The solution is to run the following command in your terminal:

xhost +local:docker

Then try again, it should work:

docker exec -it my_container

/# rqt
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
