OpsWorksを使う際のTipsをまとめてみました。 (2015/01/23)

OpsWorks CLI

一度コンソールから実行したコマンドはCLIから実行できます。

##コマンド一覧
$ sudo opsworks-agent-cli list_commands
## クックブック更新
$ sudo opsworks-agent-cli run_command update_custom_cookbooks
## setup
$ sudo opsworks-agent-cli run_command setup
## レシピ実行
$ sudo opsworks-agent-cli run_command execute_recipes COOKBOOK::RECIPE

BerkshelfでCoffeeScript

# Gemfile
source 'https://rubygems.org'

gem 'berkshelf', '3.1.3'

# Berksfile
source 'https://supermarket.getchef.com'

cookbook 'nodejs'

# metadata.rb
depends 'nodejs'

nodejs_npm 'coffee-script'

node[:deploy][‘appshortname’]の例

参考: OpsWorksのdeploy属性

appshortnameは[Apps]で設定したアプリケーションのShort nameです。

Short nameは後から変更できないので注意しましょう。

ステージング環境を用意する場合はプロダクション環境と同じアプリケーション名にしておいた方が良いです。
