Vagrantの後継ツールOttoで自動判別、自動構築を試します。
インストール
- Ottoのバイナリを ダウンロードする
- ファイルを解凍してパスが通った場所に配置します。
- 疎通確認をします
$ otto --version Otto v0.1.1
サンプル
現在時刻をランダムなWebフォントで表示するアプリケーションを作成します。
フォルダ構成は以下。
$tree . ├ config.ru ├ Gemfile ├ Gemfile.lock ├ Procfile └ timer.rb
アプリケーション
- Gemfile
source 'https://rubygems.org' gem 'sinatra', '~> 1.4.6' gem 'thin'
- timer.rb
require 'sinatra' module Template HTML =<<-EOS <!DOCTYPE html> <html lang="ja"> <head> <meta charset="UTF-8"> <title>Timer</title> <link href='https://fonts.googleapis.com/css?family=$font-family$' rel='stylesheet' type='text/css'> </head> <body> <div style="font-size:64px;font-family: '$font-family$', sans-serif;">$font-family$</div> <div style="font-size:64px;font-family: '$font-family$', sans-serif;">$time$</div> </body> </html> EOS WEB_FONTS = %w(Roboto Lato Oswald Slabo Lora Montserrat Raleway Merriweather Arimo Bitter) end get '/' do html = Template::HTML.gsub('$time$', Time.now.strftime("%Y/%m/%d %H:%M:%S")) html.gsub('$font-family$', Template::WEB_FONTS.sample) end
- Procfile

- config.ru
require './timer' run Sinatra::Application
otto compile
アプリケーションの自動判別機能によって、Ruby向けにコンパイルされます。
$ otto compile
==> Loading Appfile...
==> No Appfile found! Detecting project information...
No Appfile was found. If thereVB is no Appfile, Otto will do its best
to detect the type of application this is and set reasonable defaults.
This is a good way to get started with Otto, but over time we recommend
writing a real Appfile since this will allow more complex customizations,
the ability to reference dependencies, versioning, and more.

otto dev
ローカル開発環境を起動します
$ otto dev
# 中略
==> Caching SSH credentials from Vagrant...
==> Development environment successfully created!
IP address: 172.16.1.27
A development environment has been created for writing a generic
Ruby-based app.
Ruby is pre-installed. To work on your project, edit files locally on your
own machine. The file changes will be synced to the development environment.
When you're ready to build your project, run 'otto dev ssh' to enter
the development environment. You'll be placed directly into the working
directory where you can run 'bundle' and 'ruby' as you normally would.
You can access any running web application using the IP above.
otto dev ssh
VMにSSH接続をし、sinatraのWebアプリケーションを起動します。
