Multiple sites: trellis/ subfolder

I will have a bash, I just wondered what the correct procedure would be to do this.

I can understand that the server.yml would set up the server with all the necessary software and I’m ok with that and using successfully so far.

I can understand the deploy.yml file will deploy said theme and codebase and restart nginx for any particular dev project i have running locally from a git base.

What i need to do if i understand this correctly, is run another deploy from another local dev site to that same server. What I am unsure of is will nginx recognise the second site and will it be setup correctly on that server to handle the second site without having to run another server.yml, which will probably destroy the first site…

My idea is to run a single droplet just for staging sites as they will not be getting much load, and maybe another single droplet for production sites that are very small in size and traffic, thus saving costs etc and management time.

Its just an idea, i did addrsss it pretty poorly here Trellis with Nginx Virtual Hosts on a single Digital Ocean Droplet but @ben said it wasn’t a very good idea but I’m unsure why?
