I am not sure as I haven't tried but as long as there is network communication between the two instances you should be able to use the plugin.
Just make sure that you properly configure the IPs and ports so that each instance can connect to the other.
Oke so I should keep it running always i guess. Thx in any case. I will try to keep that running besides my docker. Still pretty new to it
Besides all keep up the good work. It's a amazing plugin!
