Question

Chef seems to be processing resources in a strange order, causing my build to fail. My main recipe (mytardis-chef/site-cookbooks/recipes/default.rb) starts like this:

include_recipe "build-essential"
include_recipe "mytardis::deps"
include_recipe "mytardis::nginx"
include_recipe "mytardis::postgresql"

mytardis-chef/cookbooks/build-essential/recipes/default.rb looks like this:

case node['platform']
when "ubuntu","debian"
  %w{build-essential binutils-doc}.each do |pkg|
    package pkg do
      action :install
    end
  end
when "centos","redhat","fedora","scientific"
  %w{gcc gcc-c++ kernel-devel make}.each do |pkg|
    package pkg do
      action :install
    end
  end
end

… (it’s an older version of https://github.com/opscode-cookbooks/build-essential/blob/master/recipes/default.rb)

At runtime, for reasons I don’t understand, this build-essential recipe gets loaded but not executed:

That is, the build-essential recipe is “found” and “loaded”, but it’s the postgres recipe that gets “processed” first. And since build-essential (which installs the C compiler) wasn’t run, the latter fails.

The relevant part of my Vagrantfile looks like this:

  config.vm.provision :chef_solo do |chef|
     chef.log_level = :debug
     chef.cookbooks_path = ["mytardis-chef/site-cookbooks", "mytardis-chef/cookbooks"]
     chef.roles_path = "mytardis-chef/roles"
     chef.data_bags_path = "mytardis-chef/data_bags"
     chef.add_recipe "mytardis"    
  end

I was previously using a slightly earlier version of Chef (perhaps 10.10.0?) In that version, build-essential was also not being run, but mytardis::deps was. Now using Chef 10.12.0. Physical machine is OSX, VM is Ubuntu Lucid.

So, a few questions:

1. Why is build-essential not being “processed”?
2. What’s the right way to do this? (I didn’t write these recipes, and I understand they do or have worked for their author.)
3. Should the site-cookbooks and cookbooks ‘shadowing’ feature still work? It’s supposedly deprecated: http://tickets.opscode.com/browse/CHEF-2308 (I tried making a symbolic link under from site-cookbooks/mytardis/recipes/build-essential but no joy).

Answer 1

It turns out this is a pretty normal (but under-documented) part of how Chef works: it compiles everything, and then starts running. Except some recipes (like Postgres) jump the queue to actually install at compile-time, using code like this:

  action :nothing
end.run_action(:run)

The solution is that anything that needs to run before Postgres also needs to do this. Fortunately, newer versions of Build-essentials allow this. You set attributes on a role as follows:

name "myapp"
run_list(
  "recipe[build-essential]",
  "recipe[myapp]"
)
default_attributes(
  "build_essential" => {
    "compiletime" => true
  }
)
