I’m using this as a base
My architecture is the following, I’m using docker compose in Unraid (probably not relevant) but what I want is
I want to have this Nexcloud service based on the docker compose below in a VLAN, and I need to integrate the web service (nginx fpm) to be with my nginx proxy that is on another VLAN in 10.10.50.10.
So I guess that in order to achieve that I need to give an external IP (10.10.40.160) to the fpm service so it can connect with my nginx docker (not part of the compose) in another VLAN.
So based on that I did this docker compose

This are the paths of the setup of the compose, I did it this way due to this parameter (build: ./web)
And I edited the nginx.conf like this to replace app:9000 for the nginx IP
then when I run it I get this error
nginx-fpm | nginx: [emerg] host not found in upstream “app:9000” in /etc/nginx/nginx.conf:33
nginx-fpm | 2023/04/21 13:07:23 [emerg] 1#1: host not found in upstream "app:9000" in /etc/nginx/nginx.conf:33

I’m sure there are more than one thing wrong in the docker compose, but I need help
- Fix de docker compose
- Configure the other nginx configuration in the nginx docker to work with nextcloud using fpm
- How do I configure my nginx docker? do I need to expose port 9000 or from a network point of view what conectivity is required?
The configuration should be based on this, but not sure about the paths or any reference to the 9000 port
How should I change the configuration of nginx in 10.10.50.10 to connect it with Nextcloud using fpm?
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name nextcloud.*;
include /config/nginx/ssl.conf;
client_max_body_size 0;
location / {
include /config/nginx/proxy.conf;
include /config/nginx/resolver.conf;
set $upstream_app nextcloud;
set $upstream_port 443;
set $upstream_proto https;

}
}
) Docker has an internal DNS daemon which is very handy when it comes to inter-container communication: all containers connected to the same network can resolve each other using “service” name or
