Docker Machine과 Docker Compose로 Rails를 구축해 보도록 하겠습니다.
TL;DR
Docker Machine와 Docker Compose가 발표를 했기 때문에 나는 즉시 Rails가 시작할 수 있는 곳을 만들어 보았다.
개발 환경으로 활용하겠다는 구상이 적혀 있다.
Enviroment
Install
Virtualbox
설치를 위해 https://www.virtualbox.org/에서 Installer를 다운로드합니다.
docker-machine
URL에 버전이 포함되어 있습니다. 최신 버전을 적절하게 교체하십시오.$ curl -L https://github.com/docker/machine/releases/download/v0.1.0/docker-machine_darwin-amd64 > /usr/local/bin/docker-machine
$ chmod +x /usr/local/bin/docker-machine
docker-compose
URL에 버전이 포함되어 있습니다. 최신 버전을 적절하게 교체하십시오.$ curl -L https://github.com/docker/compose/releases/download/1.1.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

Docker Machine에서 Docker Compose로 Rails 구축
Setup
Rails를 작성합니다.Database는 mysql에 있습니다.--skip-bundle 옵션에gem가 설치되지 않습니다.DockerImage 제작 시 설치에 사용됩니다.$ gem install rails
$ rails new docker-compose-rails --database=mysql --skip-bundle
$ cd docker-compose-rails
config/database.yml
Docker에서 시작하는 Mysql에 대한 연결 정보를 설정합니다.
Docker는 시작할 때 환경 변수를 자동으로 설정합니다.default: &default

pool: 5
username: root

environment:
DATABASE_URL: mysql2://root:supersecretpass@db:3306
Build
Gemfile.lock.gem 설치하지 않으므로 추가 옵션이 실행됩니다.$ bundle install --no-deployment
Rails--no-deployment를 생성합니다.$ docker-compose build
db uses an image, skipping

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.
