it seems correct.
Then I tried to run --net=my-net

sudo docker run -it --rm --net=my-net03_default --runtime nvidia --device=/dev/video0:/dev/video0 -e DISPLAY=$DISPLAY -w /opt/nvidia/deepstream/deepstream-5.1 -v /tmp/.X11-unix/:/tmp/.X11-unix nvcr.io/nvidia/deepstream-l4t:5.1-21.02-samples

Here is the docker network

docker network ls
NETWORK ID     NAME                       DRIVER    SCOPE
e3f32f59cafa   bridge                     bridge    local
5a6f24359b00   host                       host      local

317eb9706394   none                       null      local

then when I tried to run test4 app

deepstream-test4-app -i /opt/nvidia/deepstream/deepstream-5.1/samples/streams/sample_720p.h264 -p /opt/nvidia/deepstream/deepstream-5.1/lib/libnvds_kafka_proto.so --conn-str="172.21.0.1;9092" --topic=topic01 -s 0

got error

nvbuf_utils: Could not get EGL display connection
One element could not be created. Exiting.

If I set --net=host , all works. But when I need to change to another docker network, it’ll cause the error (I want to make this container can communicate with others, that why I want to try to change the --net, even I will change --net to overlay network type)

Is there any comment on this?

I think it should be more related to docker other than deepstream
