This is a super simple cookbook that teaches you how to use pry w/in chef.
Make sure you have ruby 1.9 installed, then install these gems.
$ gem install --no-ri --no-rdoc pry pry-nav pry-doc chef
To use pry with the Omnibus chef package,
$ /opt/chef/embedded/bin/gem install --no-ri --no-rdoc pry pry-nav pry-doc
$ chef-shell # or shef
chef> require 'pry'
chef> binding.pry
$ cd chef-pry-demo && sudo chef-solo -c solo.rb -j dna.json where solo.rb and dna.json are the ones at the
root of this repository.
You will drop down to the first breakpoint attributes/default.rb. Execute whereami
to see where you are in the code. Next, execute node[:chef_pry_demo][:foobar] to see
the current value of the attribute.
See the methods and instance variables on the node object ls node, then show-doc node.save
to see the documentation for the save method. Chef internal docs aren't that great. show-doc "foo".split or
show-doc "foo".gsub are must better illustrations of how u can browse ruby documentation
with pry. Also try ls "foo" or ls 5 to see the methods available on a string and an integer.
To continue to the next example, hit Control D or type continue. Now you should be inside the default recipe.
Type whereami, notice that there is a ruby_block above you with an embedded breakpoint. Type, whereami 20
for greater context. The ruby breakpoint you are at is processed before the individual resources. This is because
it is still compile time.
Type continue once more and you will be inside the ruby_block resource. Type continue again and you will be
inside the eRubis template.
