Multiple content-server instances possible ?

Hello,

as a first time thank you very much for the great program.

I use the Calibre-content-server in an Ubuntu Linux container on a Proxmox environment, it works wonderfully.
Integrated are some libraries on different topics.

My question:
Is it possible to start several content-server instances in parallel on the Linux server, which should then be accessible from external via different ports + login user ?

Background: I want to reduce the access for individual users to single or multiple libraries, so that they can not all see or access.

Thanks in advance

Thomas
