cloudpack の 自称 Sensu芸人 の かっぱこと 川原 洋平@inokara)です。


Play という Web フレームワークがあることを教えてもらってググると Heroku だったら簡単に動かせるらしいので、まずはどげなもんかを試してみました。


Play Framework

  • Play framework
  • Play Framework
  • Scala と Java 言語で書かれたオープンソースの Web アプリケーションフレームワーク
  • MVC アーキテクチャを採用
  • 元々は Java 書かれていたが Scala 言語をサポート、その後はコア部分を Scale で書き直された
  • Ruby on Rails と Django から大きな影響を受けている
  • Webサーバーは Netty


  • Heroku
  • 泣く子も黙る PaaS の決定版
  • OS は Debian 又は Ubuntu
  • Ruby や Node.js や Scala 等をサポート
  • データベースは PostgreSQL や MySQL や Couchbase 等をサポート

Heroku の準備



Heroku Toolbelt

heroku をコマンドラインから利用出来るツールです。
ここから DL して展開してインストールしましょう。

Play Framework


MacOS X Marvericks に brew で一発。

brew install play


play コマンドを help してみる

bash-3.2$ play help
 _ __ | | __ _ _  _
| '_ \| |/ ' | || |
|  /|_|\____|\ /
||            |__/

play 2.2.3 built with Scala 2.10.3 (running Java 1.7.0_60),
Welcome to Play 2.2.3!

These commands are available:

license Display licensing informations. new [directory] Create a new Play application in the specified directory. You can also browse the complete documentation at



play new ${APP_NAME} でアプリケーションのひな形を生成します。

bash-3.2$ play new test-app
 _ __ | | __ _ _  _
| '_ \| |/ ' | || |
|  /|_|\____|\ /
||            |__/

play 2.2.3 built with Scala 2.10.3 (running Java 1.7.0_60),

The new application will be created in /Users/kappa/git/myrepo/play/test-app

What is the application name? [test-app]

Which template do you want to use for this new application?

1             - Create a simple Scala application
  2             - Create a simple Java application

> 2
OK, application test-app is created.

Have fun!

2 を選択して Java アプリケーションのひな形を作成します。

play run でアプリケーションを起動

play run でアプリケーションを起動します。

bash-3.2$ play run
[info] Loading project definition from /path/to/test-app/project
[info] Set current project to test-app (in build file:/path/to/test-app/)
[info] Updating {file:/path/to/test-app/}test-app...

[info] Done updating.

--- (Running the application from SBT, auto-reloading is enabled) ---

[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

(Server started, use Ctrl+D to stop and go back to the console...)

簡単ですね…。ちなみにアプリケーションはポート 9000 番で Listen しています。

Heroku で Play Framework を動かす: アプリケーション起動

初めての Heroku で Play

次はこのアプリケーションのひな形をあきこのままで(そのままで)Heroku にデプロイしてみましょう。

heroku コマンドを help する

bash-3.2$ heroku help

アプリケーションを Heroku に登録する


bash-3.2$ ls
myapp           test-app
bash-3.2$ cd test-app/


git init

Heroku のアプリケーションは git を介してデプロイされます。

bash-3.2$ git init
Initialized empty Git repository in /Users/kappa/git/myrepo/play/test-app/.git/

heroku create ${アプリケーション名} を実行して Heroku にアプリケーションを登録します。

bash-3.2$ heroku create xxxxx-test-app
Creating xxxxx-test-app... done, stack is cedar |
Git remote heroku added


続いて git add して git commit でローカルのリポジトリにアプリケーションを登録します。

bash-3.2$ git add -A .
bash-3.2$ git commit -m "test commit"
[master (root-commit) bcf5064] test commit

git push heroku master を実行して heroku にアプリケーションをでぷろーいします。

bash-3.2$ git push heroku master

Heroku で Play Framework を動かす: 動作確認

ペラ一枚のページですが、git に push しただけででぷろーい(公開)が完了しました。


ホントに触ってみただけですが、ここまで 15 分、Play が Heroku で Eroku てビックリしました…。

たった 15 分の Play で Heroku が Eroku て泣けた(簡単に始めることが出来ました)
