Hi @ntheanh201, thanks a lot for the contribution!

This PR looks good. But before merging this, I am wondering whether it is worth having a separate docker image for nvitop-exporter. It is very easy to install with pipx or uvx. For docker users, they can access nvitop-exporter via the docker image for uv (uvx).

docker run -it --rm --runtime=nvidia --gpus=all \
    ghcr.io/astral-sh/uv:python3.13-bookworm-slim \
    uvx nvitop-exporter

Hi @XuehaiPan, you're right about your concern. But I still think it's better when everyone gets a ready-to-run container instead of having to remember the uvx command (in the scope of my PR)
