IP down / no binding simple images

Hi,

I have a lot of problems with images which not use VIRTUAL_PORT properly : odoo, nextcloud, phpmyadmin… This is an example with phpmyadmin, I can access to it by specifying the port http://pma.wex:7040, but not only http://pma.wex, so it is not handled by the proxy. What I am doing wrong ?

version: '2.0'

services:

  my_mysql:
    environment:
      MYSQL_PASSWORD:
    image: wexample/mysql:latest
    networks:
      - reverseproxy_wex_net
    ports:
    - 7030:3306/tcp
    restart: always
    volumes:
    - /var/www/my/mysql/data:/var/lib/mysql:rw

  my_phpmyadmin:
    environment:
      - PMA_HOST=my_mysql
      - PMA_PASSWORD=thisIsAReallyNotSecurePassword!
      - PMA_USER=root
      - VIRTUAL_HOST=pma.wex
      - VIRTUAL_PORT='7040'
    expose:
      - '7040'
    image: phpmyadmin/phpmyadmin:4.7.9-1
    links:
    - my_mysql
    networks:
      - reverseproxy_wex_net
    ports:
    - 7040:80/tcp
    restart: always

networks:
  reverseproxy_wex_net:
    external: true

Other simple PHP / Apache images works fine, like this below, I can access to it using http://one.wex.

version: '2.0'

services:

  one_web:
    container_name: one_web
    environment:
      VIRTUAL_HOST: one.wex
      VIRTUAL_PORT: '701'
    # PHP / APACHE server
    image: wexample/php7:latest
    networks:
      reverseproxy_wex_net: null
    ports:
    - 701:80/tcp
    restart: always
    stdin_open: true
    tty: true

networks:
  reverseproxy_wex_net:
    external: true

# pma.wex
upstream pma.wex {
                                ## Can be connect with "reverseproxy_wex_net" network
                # pma_my_phpmyadmin_1
                server 172.16.238.5 down;
}
server {
        server_name pma.wex;
        listen 80 ;
        access_log /var/log/nginx/access.log vhost;
        location / {
                proxy_pass http://pma.wex;
        }
}

As a fix, I had to make images to use the same port as the VIRTUAL_PORT, which is not easy for every application, and remove the sense to use port binding and proxy.

As a succeed to run a phpmyadmin with a previous version I thought it was a misuse from me, but after the thirt type of really popular images I tried to run, I think there is something uclear we may fix and it drive me crasy 😭

Thank you,

I find the problem with my conf.

My mistake, I missed an underscore “_” in the VIRTUAL_HOST variable.

Everything working fine for me now.

Solved. I misunderstood ports usage and did not realize that ports and expose was reserved to a public access, not an internal usage. So I just removed everything and it just works… after days of research.
