actually run in one terminal
mono ManagerServer.exe -port 8080 -path “/whatever/user/dir1”
and in another
mono ManagerServer.exe -port 8081 -path “/whatever/user/dir2”
and you will have two instances of manager running. Databases of one located in “/whatever/user/dir1” and it listens on port 8080, databases of another located in “/whatever/user/dir2” and it listens 8081.
No Dockers and other virtualization BS.
Autostart and sending mono process in background is easily to google.
