Ruby 2.2.1 in Vagrant VM using Chef

I want to setup my new development environment for a rails app using vagrant and chef.

Goal

Clone repository (see below). Then run:

vagrant up
vagrant ssh

Finally running bundle install in app folder should work using installed ruby 2.1.2.

I already have gone through several tutorials that describe how to to this using various cookbooks and different strategies (rbenv, rvm, ruby-install, ruby-build). But although sometimes the machine could be provisioned correctly, I was never able to ssh into the machine and run bundle install without the following error message:

The program 'bundle' is currently not installed. To run 'bundle' please ask your
administrator to install the package 'bundler'

I will now present my most recent attempt based on this tutorial: http://www.gotealeaf.com/blog/chef-basics-for-rails-developers/

I have uploaded it to github here: https://github.com/denniske/vagrant-chef-ruby

After creating vagrant machine and provisioning and ssh into machine, I get the following:

vagrant@vagrant-ubuntu-trusty-64:~$ ruby -v
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]

vagrant@vagrant-ubuntu-trusty-64:~$ which ruby
/usr/bin/ruby

vagrant@vagrant-ubuntu-trusty-64:~$ bundle
Could not locate Gemfile or .bundle/ directory

vagrant@vagrant-ubuntu-trusty-64:~$ cd /usr/local/ruby/2.1.2/bin

vagrant@vagrant-ubuntu-trusty-64:/usr/local/ruby/2.1.2/bin$ ls
erb  gem  irb  rake  rdoc  ri  ruby  testrb

Problem 1: It seems the default ruby is the ruby used by chef for provisioning (1.9.3) which I do not want to use for my rails application.

bundler is successfully installed, but connected to default (wrong) ruby version.

Ruby 2.2.1 was installed into /usr/local/ruby/2.1.2.

Problem 2: By using some code like this in default.rb I seem to be able to make my ruby version the default, but then bundler does not work.

link "/usr/bin/ruby" do
  to "/usr/local/ruby/2.1.2/bin/ruby"
end

link "/usr/bin/gem" do
  to "/usr/local/ruby/2.1.2/bin/gem"
end

Does anybody has an idea how to fix this / can create a pull request to get this working?

i will not specify the cookbook implementation itself, though what you will need to achieve is the following:

  1. install your favorite ruby version (including gem).
  2. update default ruby and gem symlinks, see: /usr/bin/ruby and /usr/bin/gem.
  3. install your favorite bundler version.

you can achieve what you want by implementing minitests (see minitest, and chef-minitest-handler)

I am sorry this is not really a direct answer to my original question, but I solved the problem another way and wanted to share it with you.

I found the website rove.io and chose Languages > Ruby > rbenv > 2.1.2, downloaded the package. Then I added the bundler gem to the chef.json config in the downloaded Vagrantfile:

chef.json = {
      :rbenv => {
        :user_installs => [
          {
            :user   => "vagrant",
            :rubies => [
              "2.0.0-p647"
            ],
            :global => "2.0.0-p647",
            'gems'    => {
              '2.0.0-p647'    => [
                {
                  'name'    => 'bundler',
                  'version' => '1.10'
                }
              ]
            }
          }
        ]
      }
    }

Then I created the vagrant machine and everything just worked as it should.

Note: I already tried using rvm and chef before with ubuntu 14. That did not work (due to some strange errors). But the ubuntu version used by the rove.io Vagrantfile works.

Seems there is an issue with the gem_package command.

I was able to make it work by replacing with an execute resource as

execute "install gem" do
  command "gem install bundler --no-rdoc --no-ri"
end

and remove

gem_package 'bundler' do
  options '--no-ri --no-rdoc'
#  gem_binary "/usr/local/ruby/2.1.2/bin/gem"
end
