DOMAIN_NAME environment variable not working

Hi, thanks a lot for your great work.

I am trying to specify custom DNS by using DOMAIN_NAME environment variable but it did not work.
I read your code a bit and I have debugging something interresting.

// src/Synchronizer.php:120
// Global
if (!empty($container['NetworkSettings']['IPAddress'])) {
    $ip = $container['NetworkSettings']['IPAddress'];

    $lines[$ip] = implode(' ', $this->getContainerHosts($container));
}

For me this condition cannot be true because $container['NetworkSettings']['IPAddress'] is null or empty.

I just move $lines[$ip] = implode(' ', $this->getContainerHosts($container)); to line 130 just after $ip declaration and it work great.

I don't know if it's really a bug or this problem come from my setup.

Maybe I have to specify an other thing to make it work ?

Docker version 20.10.6, build 370c289
docker-compose version 1.28.6, build 5db8d86f

Best regards

Compatibility with docker-machine

I suggest to deprecate environment variable DOCKER_ENTRYPOINT, and replace in code

$client = new DockerClient([], $input->getOption('entrypoint'));

 $client = DockerClient::createWithEnv();

It should add docker-machine compatibility

arm64 arch support

any chance to get a docker image built for arm64?

Allow to register several hosts

For one container, allow to register several hosts.

i.e.

my_container:
    environment:
        - EXTRA_HOSTS=toto.com,www.toto.com,bob.tata.com

Services compatibility (docker-compose)

Bonjour Luc :)

I recently discover you amazing tool, but it only works partially for me.
I am using docker-compose with version: '2' and 'services. But it doesn't take the DOMAIN_NAME from environment.

for exeample:
given

version: '2'

services:

  app:
    container_name: my_app
    image: 5.3.29-apache
    ports :
      - 80:80
    environment: 
     - DOMAIN_NAME=www.myapp.com

my hosts file will look like :

172.18.0.3 app.foldername_default 25e65f49.foldername_default foldername_app.foldername_default

Is there any solution to use the domainname env in this example and maybe take also the container_name ?

I tried to take a look at your code, but it's too complicated for me to fix it myself.

Merci beaucoup pour ton aide.

Add support for jwilder/nginx-proxy

check for a jwilder/nginx-proxy container
then use VIRTUAL_HOST environment variables

Hello, I have tried using the manager on mac - it works as expected. The IP is resolved correctly, but ping custom.address give a timeout - I cannot ping the container. Do you have any ideas what could be the reason. I am using a native Docker for Mac.

Use network name

When defining a network like

app:
     net: my_network

there should be an extra host named app.my_network

Docker for Windows

It look like it is with Docker-toolbox as I understand, but it is with Docker for windows ?

My hosts are successfully updated but nothing respond other that on localhost:8080

Windows support

Hey guys, does it work on windows? Cannot test it at the moment.

Support for multiple domains per container

If you're working with an app which supports multi-tenant setups, your HTTP container should respond to multiple hostnames (by the used hostname, application behaves differently).

For example:

www.shop.com.loc -> English, international content
www.shop.de.loc -> local German content

It would be cool if you could name multiple predefined hosts to use.

Create a package on packagist

I would like to install the project with composer:
composer global require iamluc/docker-hostmanager

Branch "develop" broken

We need this fix docker-php/docker-php-api#1 (at least)

--restart option doesn't work on Ubuntu 16.04

The docker image doesn't load on system startup on Ubuntu 16.04 LTS with the command you provided :
$ docker run -d --name docker-hostmanager --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /etc/hosts:/hosts iamluc/docker-hostmanager

It worked flawlessly on Debian 8, though.
At the moment, I have to launch docker start docker-hostmanager manually.

domainname key is ignored

Hello,

it seems domainname key is ignored and onlly env variable DOMAIN_NAME is taken into account.

Docs: https://docs.docker.com/compose/compose-file/#/cpu-shares-cpu-quota-cpuset-domainname-hostname-ipc-mac-address-mem-limit-memswap-limit-privileged-read-only-restart-shm-size-stdin-open-tty-user-working-dir

Bug with docker 1.10 ?

The container is restarting.

Run a phar instead of php files.

This allow to run the hostmanager without docker.
