Generate a Docker-Compose Yaml file 

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'dockercompose-generator'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install dockercompose-generator

## Usage

```ruby
generator = DockerCompose::Generator
mysql = generator.create_service('db', 'mysql:5.6')
mysql.add_environment('mysql_root_password', 'root')
mysql.add_environment('mysql_database', 'test')
mysql.add_environment('mysql_user', 'test')
mysql.add_environment('mysql_password', 'test')
elastic = generator.create_service('elastic', 'elasticsearch:1.4')
web = generator.create_service('web', 'php:5.6-apache')
web.add_link(elastic)
web.add_link(mysql, 'mysql')
puts generator.to_yaml
```

will output

```yaml
db:
  image: mysql:5.6
  environment:
    MYSQL_ROOT_PASSWORD: root
    MYSQL_DATABASE: test
    MYSQL_USER: test
    MYSQL_PASSWORD: test
elastic:
  image: elasticsearch:1.4
web:
  image: php:5.6-apache
  links:
  - elastic
  - db:mysql
```

## TODO

- ~~Support more options than `links`, `ports`, and `environment` variables~~
- ~~Add an Importer to seed the services~~
