Default/catch-all site

[gerwinov]

Hi @gilyes,

I have a question regarding my docker-compose file. I would like to setup a default / catch all website that is being displayed when no other virtual host is met. Currently I get a standard 503 page from nginx as default. Below is my docker-compose file. The current setup is working for the service where a specific virtual host is present. It is nog working for the default-site. I am trying to set the 'default-website' as default. Can you maybe spot the error and help me configuring this?

version: "2"

  services:
    nginx:
      restart: always
      image: nginx
      container_name: nginx
      ports:
        - "80:80"
        - "443:443"
      volumes:
        - "/etc/nginx/conf.d"
        - "/etc/nginx/vhost.d"
        - "/usr/share/nginx/html"
        - "./volumes/proxy/certs:/etc/nginx/certs:ro"

    nginx-gen:
      restart: always
      image: jwilder/docker-gen
      container_name: nginx-gen
      volumes:
        - "/var/run/docker.sock:/tmp/docker.sock:ro"
        - "./volumes/proxy/templates/nginx.tmpl:/etc/docker-gen/templates/nginx.tmpl:ro"
      volumes_from:
        - nginx
      entrypoint: /bin/sh -c
      command: ["/usr/local/bin/docker-gen -notify-sighup nginx -watch /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf"]

    letsencrypt-nginx-proxy-companion:

      volumes_from:

    XXXX:
      image: XXXX/YYYY
      container_name: XXXX
      volumes:
        - './XXXX:/config'
      ports:
        - 'YYYY:YYYY'
      environment:

        - VIRTUAL_NETWORK=nginx-proxy
        - VIRTUAL_PORT=YYYY
        - LETSENCRYPT_HOST=YYYY
        - LETSENCRYPT_EMAIL=ZZZZ
      restart: always

    default-website:
      restart: always
      image: default-website
      build: ./default-website
      container_name: default-website
      volumes:
        - "./volumes/nginx-default/conf.d/:/etc/nginx/conf.d"
      environment:
        - VIRTUAL_HOST=????
        - VIRTUAL_NETWORK=nginx-proxy
        - VIRTUAL_PORT=80

Thanks in advance!

I think DEFAULT_HOST is the environment variable you are looking for: https://github.com/jwilder/nginx-proxy#default-host

Thanks for your quick reply.

I tried it like this:

    nginx-gen:
      restart: always
      image: jwilder/docker-gen
      container_name: nginx-gen
      volumes:
        - "/var/run/docker.sock:/tmp/docker.sock:ro"
        - "./volumes/proxy/templates/nginx.tmpl:/etc/docker-gen/templates/nginx.tmpl:ro"
      volumes_from:
        - nginx
      entrypoint: /bin/sh -c
      environment:
        - DEFAULT_HOST=XXXX (same name as one VIRTUAL_HOST further down in the file)
      command: ["/usr/local/bin/docker-gen -notify-sighup nginx -watch /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf"]

This however does not seem to work. When I visit my server by IP address I get a 503 nginx error. Do you have any suggestions?

Thanks in advance!

Best regards, Gerwin

Haven't tried this but it looks good to me... Did you recreate the containers?

BTW, you can check the generated nginx config with docker exec nginx cat /etc/nginx/conf.d/default.conf

Recreating the containers (using docker-compose up --force-recreate) did the trick for me. Rookie mistake I guess.. Thanks a lot!
