docker-compose - The domain name was not added to hosts file

[FDiskas]

The domain name was not added to hosts file I'm using docker-compose syntax version 2.

version: '2'
services:
    web:
        container_name: test
        build:
            context: .docker
        volumes:
            - .:/var/www/html
        environment:
            DOMAIN_NAME: "dynamic-ads.dev,www.dynamic-ads.dev"
        ports:
            - 80:80

docker inspect test

"Env": [
                "DOMAIN_NAME=dynamic-ads.dev,www.dynamic-ads.dev",
                "affinity:container==0a8de1646a1a4903bc771f17589bc341762b3750a2d7f54767e4d383fd1c6b44",

            ],

but /etc/hosts file looks like

## docker-hostmanager-end

I confirm it is an issue for docker-compose v2

[iamluc]

If I remember well, the problem is that with v2, a container has 1 IP by network and can be in several networks. But we can only register 1 IP by domain name.

Nevertheless, It should be possible to extend domain name declaration, or to use the domain name when the container is connected to only 1 network.

Yes please fiix this.

any news on this? imho with v2 and v3 this is badly needed

[bernhardberger]

I experimented a bit for my local dev environment and came to the following solution:

Synchronizer.php:

if (isset($container['Config']['Labels']['tld.mycompany.docker-hostmanager.network.' . $networkName . '.vhost'])) {
                    $hosts[] = $container['Config']['Labels']['tld.mycompany.docker-hostmanager.network.' . $networkName . '.vhost'];
                }

and in docker-compose.yml:

services:
   web:
     - tld.mycompany.docker-hostmanager.network.${COMPOSE_PROJECT_NAME}_default.vhost=my-virtual-domain.tld

This way I can match my hosts entry to specific networks (or in this case the default network). I won't do a pull request though as it compromises your DOMAIN_NAME compatibility requirements and follows a slightly different approach for configuring. However I want to leave it here as an idea on how this could be resolved

This feature would be really appreciated :)

Hey guys, any news about this ? In my tests today, the only docker-compose.yaml that works, is this:

db:
    image: mysql:5.6
    #volumes:
    #    - .data/db:/var/lib/mysql
    restart: always
    environment:
        MYSQL_ROOT_PASSWORD: root
        MYSQL_DATABASE: mydb
        MYSQL_USER: root
        MYSQL_PASSWORD: root
web:
    image: nginx:latest
    ports:
        - "80:80"
        - "443:443"
    volumes:
        - ./project:/project
        - ./conf.d/site.conf:/etc/nginx/conf.d/site.conf
        - ./ssl:/etc/nginx/ssl
    environment:
        DOMAIN_NAME: my-php-project.test 
    links:
        - php
php:
    image: php:7-fpm
    volumes:
        - ./project:/project

If i try to use the version 2 or 3, does not work:

version: "2"
    services:
        db:
            image: mysql:5.6
            #volumes:
            #    - .data/db:/var/lib/mysql
            restart: always
            environment:
                MYSQL_ROOT_PASSWORD: root
                MYSQL_DATABASE: mydb
                MYSQL_USER: root
                MYSQL_PASSWORD: root
        web:
            image: nginx:latest
            ports:
                - "80:80"
                - "443:443"
            volumes:
                - ./project:/project
                - ./conf.d/site.conf:/etc/nginx/conf.d/site.conf
                - ./ssl:/etc/nginx/ssl
            environment:
                DOMAIN_NAME: my-php-project.test 
            links:
                - php
        php:
            image: php:7-fpm
            volumes:
                - ./project:/project

Hi @felipemarques Indeed, the DOMAIN_NAME environment variable is only used when your container use only the default "Bridge" network (== docker-compose file version 1)

We are discussing about this in https://github.com/iamluc/docker-hostmanager/pull/34
