I'm using Node-Red in Docker on a Pi and also on Ubuntu->VirtualBox->Windows. It is brilliant. I can easily spin up multiple containers that map different external ports to 1880 so the Node Red config is identical. Very handy for different projects or testing.
If you go down the Docker path, you should also look at Portainer (which also runs under Docker) to manage/monitor your Docker containers. If nothing else, it simplifies using SSH to connect.
