Either you run the RP in the VPS and point to the ips on your server or you run it on the server and access it like you are accessing Jellyfin.
Easiest option is a container with Nginx proxy manager (imo) with NPM you can get free let’s encrypt certs, but be aware, in case you want automated certificates, NPM will need to run on the machine pointed to by the DNS (in your case, your VPS I guess)
Where I come from we just take the meat of the fruit and blend it with milk or water (and yes, we call that juice), I you have never try it, go get a ripe mango, blend it with milk and you’ll have a delicious smootie, you can use water but imh milk is superior for that use case.
Of cours that is no possible with oranges for example, but there a aloooooot mor fruits than oranges.
If you ever have the oportunity to have some guayaba-milk-juice, don’t pass it up, the shit is the nectar of the gods.
