Docker-letsencrypt-nginx-proxy-companion: Multiple Unique Domains (not Sub-domains)

[rene-gomez]

Hello my name's Rene from Mexico City,

I would like to have multiple domains in the same IP, like a VPS with docker.
In this moment I have tree domains which are: bar.com, foo.com and like.org
My main site is bar.com.
Only at bar.com do I have a let's encrypt certificate, the foo.com and like.org redirect is for bar.com certificate, when you open foo.com the browser says: "Your connection is not secure" if I add an exception the certificate shown is for bar.com

Thanks in advance

My configuration in docker-compose

version: "2"
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - /var/www/vhost.d:/etc/nginx/vhost.d
      - /var/www/certs:/etc/nginx/certs:ro
      - /usr/share/nginx/html

  proxy-companion:
    image: jrcs/letsencrypt-nginx-proxy-companion
    restart: always
    volumes:
      - /var/www/certs:/etc/nginx/certs:rw
      - /var/run/docker.sock:/var/run/docker.sock:ro
    volumes_from:
      - nginx-proxy

networks:
  default:
    external:
      name: nginx-proxy

---

The configuration of the domains is

version: '2' 
services: 
  DEMO-DB1: 
    image: mariadb:latest 
    volumes: 
      - ./database/:/var/lib/mysql     
    restart: always 
    environment: 
      MYSQL_ROOT_PASSWORD: example
      MYSQL_DATABASE: example
      MYSQL_USER: exampleusar
      MYSQL_PASSWORD: examplexy

  DEMO-WP1: 
    depends_on: 
      - DEMO-DB1
    image: wordpress 
    restart: always
    environment:
      VIRTUAL_HOST: bar.com      
      VIRTUAL_PORT: 8001
      VIRTUAL_PORT: 8002
      LETSENCRYPT_HOST: bar.com, www.foo.com
      LETSENCRYPT_EMAIL: [email protected]
      WORDPRESS_DB_HOST: DEMO-DB1:3306 
      WORDPRESS_DB_NAME: dbuser ,
      WORDPRESS_DB_USER: datauser 
      WORDPRESS_DB_PASSWORD: example 
    volumes: 
      - ./html:/var/www/html 
      - ./php.ini:/usr/local/etc/php/conf.d/uploads.ini

networks:
  default:
    external:
      name: `nginx-proxy`

My second and third domain are the same on bar.com Docker Compose files, only difference is the VIRTUAL PORT variable

The domains are independent and work good, the problem is only with the certificate.

Sorry that's not readable, could you try using mardown's "insert code" button to have your compose files displayed properly ?

[rene-gomez]

@buchdag Ok.

Thanks for your time

Let say you have those domains and subdomains all pointing to your host's IP:

• bar.com
• ww.bar.com
• foo.com
• www.foo.com

If you have only one service running on your host's docker and you want all those domains/subdomains proxyed to the same container with SSL for all of them you'll have to do something this:

[...]
services: 
  [...]

  your_proxyed_service: 
    [...]
    environment:
      VIRTUAL_HOST: bar.com, www.bar.com, foo.com, www.foo.com
      VIRTUAL_PORT: XXXX
      LETSENCRYPT_HOST: bar.com, www.bar.com, foo.com, www.foo.com
      LETSENCRYPT_EMAIL: [email protected]
     [...]

Every domain and subdomain that you want to be proxyed to the container must be explicitely declared in the VIRTUAL_HOST variable. Wether there is a redirect or not at the DNS level is an entirely different thing.

The same goes for the LETSENCRYPT_HOST variable.

The VIRTUAL_PORTmust be declared only once for each proxyed container and set to a single port you know to be exposed by the container.

Thanks for the support, only i have one nginx-proxy and one proxy-companion and i have a service for each site, so I need a DNS for this, do you know a project for this?

Thanks in advance

Hi,

Thanks for your support, in this tread:

https://github.com/JrCs/docker-letsencrypt-nginx-proxy-companion/issues/187

I remove the space caracteres and works!

This is my Docker-compose file for each site:

version: '2' 
services: 
  EW-DB1: 
    image: mariadb:latest 
    volumes: 
      - ./database/:/var/lib/mysql 
    restart: always 
    environment: 
      MYSQL_ROOT_PASSWORD: someone
      MYSQL_DATABASE: data
      MYSQL_USER: userex
      MYSQL_PASSWORD: example0

  EW-WP1: 
    depends_on: 
      - EW-DB1
    image: wordpress
    restart: always
    environment:
      VIRTUAL_HOST: foo.com, www.foo.com
      VIRTUAL_PORT: 8002
      LETSENCRYPT_HOST: bar.com,foo.com,www.foo.com
      LETSENCRYPT_EMAIL: [email protected]
      WORDPRESS_DB_HOST: EW-DB1:3306 
      WORDPRESS_DB_NAME: database
      WORDPRESS_DB_USER: username
      WORDPRESS_DB_PASSWORD: example
    volumes: # this is where we tell Docker what to pay attention to
      - ./html:/var/www/html
      - ./php.ini:/usr/local/etc/php/conf.d/uploads.ini

networks:
  default:
    external:
      name: nginx-proxy

Thanks for your suppor.
