Your First Cookbook

Install Ruby With Chef

We are going to use the rbenv cookbook to install ruby. First we need ot add the rbenv cookbook as a dependency in our metadata file

depends 'rbenv', '1.7.1'

Next use Berkshelf to grab this cookbook form the chef supermarket

$ berks install

Now we can use the rbenv_ruby resource to install ruby globally on the vagrant machine.

rbenv_ruby 2.1.1 do
  global true
end

Run $ kitchen setup default-centos to bring up vagrant and apply the recipe Run $ kitchen login default cenotos to ssh into the box. On the vagrant machine run ruby --version The command should print 2.1.1 to the console. $ exit

exercise: Extract the ruby version into an attribute

exercise: using the rbenv cookbook documentation, install bundler

Start application. You should see a database error.
