Multiple nginx configs on docker?

Question

Nginx

Good morning!

I have several projects that are on 1 server
How can I configure nginx in docker-compose so that it uses several configs

At the moment my docker-compose.yml looks like this:

version: '3.6'
services:
  postgres:
    image: postgres:12
    restart: always
    volumes:
    - db_data:/var/lib/postgresql/data
    environment:
      POSTGRES_USER: qwe
      POSTGRES_PASSWORD: qwe
      POSTGRES_DB: qwe
  graphql-engine:
    image: hasura/graphql-engine:v1.2.2
    ports:
    - "8080:8080"
    depends_on:
    - "postgres"
    restart: always
    environment:
      HASURA_GRAPHQL_DATABASE_URL: postgres://qwe:[email protected]:5432/qwe
      HASURA_GRAPHQL_ENABLE_CONSOLE: "true" # set to "false" to disable console
      HASURA_GRAPHQL_ENABLED_LOG_TYPES: startup, http-log, webhook-log, websocket-log, query-log
      ## uncomment next line to set an admin secret
      HASURA_GRAPHQL_ADMIN_SECRET: admin
  backend:
    build: ./backend/
    container_name: backend
    restart: always
    ports:
      - '4000:4000'
    env_file:
      - ./backend/.env
  nginx:
    restart: always
    image: nginx:stable
    container_name: hasura-nginx
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /root/certs/:/root/certs/
      - ./nginx:/etc/nginx/conf.d
    depends_on:
      - graphql-engine
volumes:
  db_data:

/nginx/default.conf

server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  server_name hasura.test.ru;

  ssl_certificate /root/certs/cert.crt;
  ssl_certificate_key /root/certs/cert.key;

  location / {
    proxy_pass http://graphql-engine:8080/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }
}

server {
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  server_name api.test.ru;

  ssl_certificate /root/certs/cert.crt;
  ssl_certificate_key /root/certs/cert.key;

  location / {
    proxy_pass http://backend:4000;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

How to make graphql-engine and backend have their own docker-compose.yml?
At the moment, this method works, but in order to update any service, you have to rebuild all these components

Answer 1

here, not "for example" is needed, but configs, a description of containers, and what listens where and where it proxies.
In general, look at dokku - there is nginx and built-in proxying, just say which container to bind to which host / port.

Answer 2

During development, you can take a proxy that generates an nginx config based on running containers. For example, in my work I use this https://github.com/spaceonfire/localhost-docker
On the server, of course, it is better to take some kind of kubernetes or the previously mentioned dokku
