Is it possible/practical to host multiple websites from the same VPS server?
I have a number of domains (for example): bilbobaggins.com, rx4free.com, mypersonalblog.com
I don’t get much traffic and I’m not interested in paying for separate servers for each domain. But I still want https certificates to work properly.
Now I’m familiar with setting up wildcard subdomains with traefik and letsencrypt. But can I do the same or similar with completely different domains such as listed above?
Yep, what you're looking for is a reverse proxy. All the incoming traffic to the server goes though it, typically on TCP port 80 or 443. Reverse proxy then directs the traffic to all the backend apps. The backend apps can be literally anywhere else or even on the same server on a different port.
Traefik, Caddy, Nginx Proxy Manager, Linuxserver SWAG are the popular choices these days. See which one fits you best.
Edit: Overlooked you mentioning you are already using Traefik. Subdomain, domain, makes no difference. Just point the DNS record to your VPS and have Traefik direct it towards the correct port on the same server.
