I have tried nvidia-docker --version, but it seems just showing docker's version.
After some investigation of official documents, I could not find any information about this.
How to check nvidia-docker 's version?
It's better to use docker version, it gives you more details. This command works for nvidia-docker too, we add a single line on top of the output.
$ nvidia-docker version

I found an answer (on Ubuntu):
dpkg -l | grep nvidia-docker
