Hi there. I have been struggling to set various services like
portainer, nginx proxy manager, nextcloud, and other services to point
to a subdomain like: [sub.mydomain.com](https://sub.mydomain.com)

I'm using a dedi machine that is rented from abroad. The machine is
primarily used for a project related to a Minecraft game server. A web
server related to this is already set up and working just fine (Via
Nginx).

I have encountered various issues with this. Bad Gateway errors, Port
conflict errors, and so on.
I was hoping someone here might have the time and be willing to assist
me in the process over a discord call.

I currently have access to Portainer and NginxProxyManager via
[https://publicip](https://publicip):port

Are all your services in the same docker network?

Researching a bit and slowly trying to understand how docker works.
Some of my services are on the same network. Do they all need to be on
the same network or should they be separated?

Point the subdomains to your server and have nginx proxy requests. The
server blocks just need the server_name property to the respective
block’s subdomain. Read up on the nginx docs for how it works. It’s a
main use case of reverse proxies.

Each container has an exposed port on your server (8080, 9000, etc).
Nginx Proxy Manager should be mapped to port 80 and 443 on your
server.

In nginx you map the subdomain (xxx.domain-name.xx) to your docker
server ip:port. That is how the reverse proxy matches the incoming
request (url) to the internal port (container) on your server).

For nginx to reach them they would need to be on the same network. I
would just make a nginx network and add nginx and other containers
that need internet to it
