Using IP to access site while migrating


Hey guys!

So, I’m completely new to EE (and also docker) but I decided I would give it a try on one of my current projects.

What I need to do:
I would like to create a WP site on a DigitalOcean droplet which I’ll prep to be the new home of an existing WP site - meaning I would like to set everything up and then point the domain to it. For this I need to be able to access the EE WP via the droplet IP for the time being.

My situation:
No matter what I try I’m greeted with a 503 from NGINX. I’ve had no luck searching the EE documentation and my attempts to create a redirect / listen / change server_name in the custom NGINX conf have all failed so far. Googling has only provided my with solutions relevant to V3 which seems not to use docker and instead relies on the usual sites-enabled way of configuring things with which I am familiar - but I couldn’t really apply any of it to V4.

Of course, if I site create a WP and set the name to the IP address of the droplet I can access it with no problem - however, I think this is a very bad workaround seeing as I will have to change literally everything once I do point the domain to it.

Any help would be truly appreciated and I’m very sorry if I’ve missed something obvious in the docs.
