Change nginx server name in Docker - docker

Question

I have a project running on docker. I use Nginx reverse proxy to run my app.
All works fine but trying to personalize the server_name on nginx but couldn't figure out how.
Docker yml file
I've added server name to /etc/hosts by docker
version: "3"
services:
nginx:
container_name: nginx
volumes:
- ./nginx/logs/nginx:/var/log/nginx
build:
context: ./nginx
dockerfile: ./Dockerfile
depends_on:
- menu-app
ports:
- "80:80"
- "433:433"
extra_hosts:
- "www.qr-menu.loc:172.18.0.100"
- "www.qr-menu.loc:127.0.0.1"
networks:
default:
ipv4_address: 172.18.0.100
menu-app:
image: menu-app
container_name: menu-app
volumes:
- './menu-app/config:/var/www/config'
- './menu-app/core:/var/www/core'
- './menu-app/ecosystem.json:/var/www/ecosystem.json'
- './menu-app/tsconfig.json:/var/www/tsconfig.json'
- './menu-app/tsconfig-build.json:/var/www/tsconfig-build.json'
- "./menu-app/src:/var/www/src"
- "./menu-app/package.json:/var/www/package.json"
build:
context: .
dockerfile: menu-app/.docker/Dockerfile
tmpfs:
- /var/www/dist
ports:
- "3000:3000"
extra_hosts:
- "www.qr-menu.loc:127.0.0.1"
- "www.qr-menu.loc:172.18.0.100"
networks:
default:
ipam:
driver: default
config:
- subnet: 172.18.0.0/24
And I have Nginx conf
server_names_hash_bucket_size 1024;
upstream local_pwa {
server menu-app:3000;
keepalive 8;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name www.qr-menu.loc 172.18.0.100;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
location / {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://local_pwa/;
}
}
but unfortunately, app runs on localhost instead of www.qr-menu.loc
I couldn't figure out how to change server_name on Nginx.

This is a really, really late answer. The server_name directive tells nginx which configuration block to use on receipt of a request. Also see: http://nginx.org/en/docs/http/server_names.html
I think the docker-compose extra_hosts directive might only work for domain-name resolution within the docker network. In other words, on your computer that's running docker the name "www.qr-menu.loc" is not available, but in a running docker container that name should be available.
