Jetpack 4.3 CSI Camera Support from within Containers

Can you try launching Docker with these flags?

sudo docker run --net=host --runtime nvidia --rm --ipc=host -v /tmp/.X11-unix/:/tmp/.X11-unix/ -v /tmp/argus_socket:/tmp/argus_socket --cap-add SYS_PTRACE -e DISPLAY=$DISPLAY -it nvcr.io/nvidia/l4t-base:r32.2.1

Note the –ipc=host and -v /tmp/argus_socket:/tmp/argus_socket arguments.
