itamaeでrbenv入れるのにはまった恥ずかしい話

ec2でrbenv入れるのにitamaeで入れようとしてたのですが、
rbenvのインストール手順を普通になぞっていったら地味にはまってしまいました。

最初に書いたレシピはこんな感じ
rbenv/default.rb

%w(
  git
  gcc-c++
  glibc-headers
  openssl-devel
  readline
  libyaml-devel
  readline-devel
  zlib
  zlib-devel
  libffi-devel
  libxml2
  libxslt
  libxml2-devel
  libxslt-devel
  sqlite-devel
  mysql-devel
  patch
).each do |pkg|
  package "#{pkg}" do
    action :install
  end
end

git '/usr/local/rbenv' do
  repository 'https://github.com/sstephenson/rbenv.git'
end

directory "/urs/local/rbenv/plugins" do
  action :create
end

git '/usr/local/rbenv/plugins/ruby-build' do
  repository 'https://github.com/sstephenson/ruby-build.git'
end

remote_file "/etc/profile.d/rbenv.sh" do
  action :create
  source "files/etc/profile.d/rbenv.sh"
  owner 'root'
  group 'root'
  mode '644'
end

execute 'install ruby' do
  command("source /etc/profile.d/rbenv.sh; rbenv install 2.3.0")
  command("source /etc/profile.d/rbenv.sh; rbenv global 2.3.0; rbenv rehash")
end

実行してみるとこんな感じ

正常に終わったように見えてるが、rubyのバージョンが変わってない。。。

$ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

レシピのrubyインストール部分を以下のようにコマンドを分割する形に修正
rbenv/default.rb

execute 'install ruby' do
  command("source /etc/profile.d/rbenv.sh; rbenv install 2.3.0")
end

execute 'set ruby global' do
  command("source /etc/profile.d/rbenv.sh; rbenv global 2.3.0; rbenv rehash")
end

再度実行してみる

$ bundle exec itamae ssh -i pem/test.pem -h 172.31.21.186 roles/test.rb
 INFO : Starting Itamae...
 INFO : Recipe: /home/ec2-user/deploy/xxx/roles/test.rb

 INFO :     execute[set ruby global] executed will change from 'false' to 'true'

ちゃんとrubyのバージョンがrbenvで入れたものに変わりました

$ ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-linux]
