Itamae | Node Attributes #devops #itamae

概要

プロビジョニングツール Itamae

Node Attributes について。

json ファイルで定義した Node Attributes を利用して、
レシピの内容を動的に変更して、柔軟性を高めることが出来ます。
例えば、version指定を Node Attributes にすることで、
別バージョンを指定するだけのレシピを何度も作成せずに、
一つのレシピで管理出来ます。

前提

試行

レシピを作成

require 'itamae/plugin/resource/toilet'

node[:toilets].each do |t|
  t[:text]
  toilet t[:text] do
    filters t[:filters] if t[:filters]
  end
end

Gemfile を作成

source 'http://your_gem_server:your_port/'

gem 'itamae'
gem 'itamae-plugin-resource-toilet'
# geminabox(private gem server) から itamae-plugin-resource-toilet を install
$ bundle install
$ gem list | grep itamae
itamae (1.0.1)
itamae-plugin-resource-toilet (0.0.1)

node.json を作成

{
  "toilets": [
    {
      "text": "hoge",
      "filters": ["gay"]
    },
    {
      "text": "hige",
      "filters": ["gay", "flip"]
    },
    {
      "text": "hage",
      "filters": ["gay", "border"]
    },
    {
      "text": "hege"
    }
  ]
}
