Docker Hoster

GitHub: mrfleshka/docker-hoster

A simple "etc/hosts" file injection tool to resolve names of local Docker containers on the host.

Before start

You need to create network for detect container aliases:

docker network create _develope

Then you need to register docker-hoster.

For Windows it looks like:

docker run -d --restart=always --name docker-hoster -v /var/run/docker.sock:/tmp/docker.sock:ro -v /c/Windows/System32/drivers/etc/hosts:/tmp/hosts mrfleshka/docker-hoster python -u hoster.py --networks _develope --masks .test

Also, for Windows you need to give your current user full access to file C:/Windows/System32/drivers/etc/hosts (cuz docker-hoster will modify it later).

After this run you never return to starting docker-hoster (it will start automatically).

Configure docker-compose.yml

Next, in the docker-compose.yml file, you need to add your network as external and set up aliases for the containers:

version: '3'
services:
  nginx:
    image: 'nginx:latest'
    container_name: nginx-test
    volumes:
      - './.docker/nginx/conf:/etc/nginx/conf.d'
      - '.:/var/www/app'
      - './.docker/nginx/logs:/var/log/nginx'
    ports:
      - ${DOCKER_PORT_HTTP}:80
    networks:
        development:
            aliases:
                - mydomain.test
networks:
  development:
    external:
      name: _develope

Be sure your aliases finish with .test and written in _develope network.

And if docker-compose up for previous config, you will see next in your hosts:

#-----------Docker-Hoster-Domains----------
127.0.0.1    mydomain.test
#-----Do-not-add-hosts-after-this-line-----

You still need set up PORTS in config, but now you have dynamically updated aliasing system)
