概要

Vagrantで作成した仮想環境にItamaeでrbenvをインストールする
開発環境を自動構築したいけど、Chefが手に余る感じ（勉強不足）なのでItamaeでやってみる

Vagrant

Vagrantfile

Vagrant.configure(2) do |config|
  config.vm.box = "ubuntu-14.04"
  config.vm.box_url = "http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_ubuntu-14.04_chef-provisionerless.box"
  config.vm.network "private_network", ip: "192.168.33.109"
  config.ssh.forward_agent = true
end

$ vagrant up

Gemfile

Gemfile

source 'https://rubygems.org'

gem 'rake'
gem 'serverspec'
gem 'itamae'
gem 'itamae-plugin-recipe-rtn_rbenv'

$ bundle install --path vendor/bundle

Itamaeでruby-2.2.0インストール


# recipes/ruby.rb
include_recipe 'rtn_rbenv::system'


# nodes/node.json
{
    "rtn_rbenv": {
        "user": "vagrant",
        "versions": {
            "2.2.0": []
        },
        "global": "2.2.0"
    }
}

$ bundle exec itamae ssh -h 192.168.33.109 -u vagrant -j nodes/node.json recipes/ruby.rb -i .vagrant/machines/default/virtualbox/private_key

serverspec

$ bundle exec serverspec-init

spec/default/sample_spec.rb


require 'spec_helper'

describe command('source /etc/profile.d/rbenv.sh; which rbenv') do
  let(:disable_sudo) { true }
  its(:stdout) { should match %r{/usr/local/rbenv/bin/rbenv} }
end

$ bundle exec rake spec

rake aborted!
Circular dependency detected: TOP => spec => spec:all => spec:default => spec:all

Tasks: TOP => spec => spec:all => spec:default
(See full trace by running task with --trace)

# とりあえずRakefileの該当行をコメントアウト
#  task :default => :all


$ bundle exec rake spec

#
# テストがこけます！

よく考えてみたらubuntuなのでsourceコマンドが効かない。
（何も考えず適当にrbenvのserverspecコピペしてたのが原因）
以下のように修正

spec/default/sample_spec.rb


require 'spec_helper'

describe command('. /etc/profile.d/rbenv.sh; which rbenv') do
  let(:disable_sudo) { true }
  its(:stdout) { should match %r{/usr/local/rbenv/bin/rbenv} }
end

これで通るはず
