[chef] Re: Re: Consuming a resource/provider from within another provider

[James Dawson < >]

Many thanks for the pointer Andrea, it definitely helped me move forward and understand a bit more - but I'm still not quite there.

The method I included before now looks like this:

def installed?

  poshOutFile = "#{ENV['TEMP']}\\feature_smm_poshoutput.tmp"

  @installed ||= begin

    poshResource = Chef::Resource::Powershell.new("query feature", run_context) do

      code <<-EOH

        Import-Module ServerManager

        $feature = Get-WindowsFeature " "

        Set-Content -Path "#{poshOutFile}" -Value $feature.Installed

      EOH

    end

    poshResource.run_action(:run)

    ( ::File.exist?(poshOutFile) && ::File.read(poshOutFile).include?('True') )

  end

end

The resulting chef-run completes without error and the logging indicates that the resource was executed:

...but the 'poshOutFile' is never created suggesting that the Powershell is not actually executed.  As a test I implemented similar logic in a simple recipe calling the powershell resource directly and, as expected, this works fine.

Am I missing anything else that is needed to allow a resource to execute properly when defined dynamically?

Cheers,

James.
