Docker で PlayFramework2 の環境を作るメモ書き

DockerでPlayFrameworkが動くと聞いて試して見たメモ

Dockerfile

これを利用

最終的には Typesafe Activator が動くっぽい。

Play のプロジェクト内で docker build をする気配だったので、ちょっとやり直し。

[yasui@Yasui-MBA2: ~/Documents/develop/docker-play][15:45-09/09/14] $ ls
./		../		Dockerfile
[yasui@Yasui-MBA2: ~/Documents/develop/docker-play][15:45-09/09/14] $ play new fakeit
       _
 _ __ | | __ _ _  _
| '_ \| |/ _' | || |

|_|            |__/

play 2.2.3 built with Scala 2.10.3 (running Java 1.6.0_65), http://www.playframework.com

The new application will be created in /Users/yasui/Documents/develop/docker-play/fakeit

What is the application name? [fakeit]
>

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

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

> 1
OK, application fakeit is created.

Have fun!

[yasui@Yasui-MBA2: ~/Documents/develop/docker-play][15:46-09/09/14] $ mv Dockerfile fakeit
[yasui@Yasui-MBA2: ~/Documents/develop/docker-play][15:46-09/09/14] $ cd fakeit

ビルドできたので、起動させる

[yasui@Yasui-MBA2: ~/Documents/develop/docker-play/fakeit][16:04-09/09/14] $ docker run -i -t -p 9000:9000 myplayapp
Play server process ID is 9
[info] play - Application started (Prod)
[info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000

まぁ、こんな感じ。

ファイル更新するたびにdockerを再起動する必要があるとか、まだここら辺の対処がわかんないけど、こんな感じで動く。
