[chef] Re: Re: Re: Re: Listing all cookbooks used in an environment

[DV < >]

Thanks a lot, this works. I've added some formatting and gotten rid of "ERROR: ArgumentError: Attribute recipes is not defined!" error by adding an extra check. The error showed up because we have some node objects that don't have a runlist.

require 'chef'

Chef::Config.from_file('knife.rb')

envs = Chef::Environment.list.keys

q = Chef::Search::Query.new

envs.sort.each do |e|

  if e.include? "sandbox"

    next

  end

  puts "Environment: #{e}\n"

  constrained_cookbooks = Chef::Environment.load(e).cookbook_versions.keys

  all_cookbooks =[]

  nodes = q.search(:node, "chef_environment:#{e}").first.reject(&:nil?)

  nodes.each do |n|

    if !n or !n.has_key? 'recipes'

      next

    end

    n.recipes.map{|r| r.split('::')[0]}.each do |cookbook|

      all_cookbooks << cookbook unless all_cookbooks.include?(cookbook)

    end

  end

  puts "Unconstrained cookbooks: #{(all_cookbooks - constrained_cookbooks).join ' '}\n\n"

end

i think the bug was in the  search call, which returns an array with 3 element, first being the nodes, second is starting index and third with total nodes,

just updated the gist,

can you try agains?

Thanks :) I gave it a try and so far after correcting syntax errors it's saying that there's no recipes attribute for the array (n, I guess), so I'll have to look into that.

Hey all,

So I've been trying to write a script which will show me which cookbooks are used in an environment that are not version-locked.

I thought I have it all figured out, with the following command fetching a list of cookbooks used in an environment. It collects "recipes" attribute of all nodes in the environment and extracts cookbook names:

knife search node "chef_environment:${CHEF_ENVIRONMENT}" -a recipes| grep -v -e ^id -e ^recipes -e found$ -e ^$ | awk -F':' '{print $1}' | sed 's/^ *//; s/; */;/g' |sort|uniq

The command does its job, but it has a major downside: it doesn't list cookbooks that are not explicitly listed in the "recipes" attribute. So, for example, if "tomcat" cookbook calls "java" cookbook, and "tomcat" cookbook is assigned to some node in the environment, the command above will list "tomcat" but not "java".

Is there a better way to fetch a list of cookbooks? Or should I add logic to resolve cookbook dependencies? Thanks.
