[chef] Modelling a collection of resources as an LWRP

["Mark J. Reed" < >]

I have a set of resources that I want to invoke as a single unit, that will notify other resources if any of the sub-resources would do so.

One such set could be modeled as its own recipe, I want to be able to include multiple instances in other recipes - and you can only include another given recipe once.

So I was thinking an LWRP.  Say I want to create a group, a user who belongs to that group, a file owned by that user, and a service that requires that file to exist, in one swell foop.  The provider could look like this:

action :create do

    resources = Hash.new []

    resources[:create]  << 

       group "foo" do ... end    <<

       user "bar" do ... end     << 

       file "baz" do ... end 

    resources[:enable] = resources[:start] << service "zoo" do ... end 

    resources.each do |action, res|

        res.run_action action

       ( @new_resource.updated_by_last_action? || res.updated_by_last_action? ) 

    end

end

It seems kind of hacky to force all the resources to run immediately just so I can query their updated_by_last_action status.  Is there a better way?
