Greetings, I’m trying to connect my postgREST API that’s running from my droplet, to my main domain that’s on Digital Ocean’s app platform. I’m a little confused on how to do so because I cannot manually configure my main domain’s VM. I’m pretty new with networking like this but I believe I’m looking to set up a proxy?

Given from postgREST documentation, the nginx config file looks something like this. if my domain name from the App platform is called, DOMAIN.com, where would that be configured here? I only want my postgREST running on localhost in the VM, but can be accessed using my domains http address.

http {
  ...
  # upstream configuration
  upstream postgrest {
    server localhost:3000;
    keepalive 64;
  }
  ...
  server {
    ...
    # expose to the outside world
    location /api/ {
      default_type  application/json;
      proxy_hide_header Content-Location;
      add_header Content-Location  /api/$upstream_http_content_location;
      proxy_set_header  Connection "";
      proxy_http_version 1.1;
      proxy_pass http://postgrest/;
    }
    ...
  }
}

Would really appreciate some guidance here. thank you!
