UPDATE:
For those who would like to implement @mwolter scripts for Synology, I make some adjustments for implementing it. However, it works and you guys can just follow my guide at KRDesigns.com
Again special thanks to @fmartinou for WUD (must-have for docker user) and @mwolter for his remarkable LTS certs scripts and implementations which will work for WUD and Docker Monitor.
Who is this for?
One with multiple machines + docker running which allow you to install single WUD and single Portainer yet you will have the ability to remote and control the rest of your docker.
