I asked for docker because install from docker hub will be easier with fewer steps and remove incompatibility on servers already in place.
This implementation works, unfortunately, I don't find this version easier than installing real node.js
I was talking more about:
from registry on dockerhub download image hubconnect with one click
enter IP addresses and ports Hubremotes and hubservers in environmental variables.
done
something like this pihole docker example. deployed in 2 min.
