Your issue is that you are running some commands during the recipe compile phase, whereas resources are added to a queue called the resource collection and then evaluated after all compilation is completed (the “converge phase”). You can find some more documentation about this process here: http://docs.opscode.com/essentials_nodes_chef_run.html

 

cmd = powershell_out(script)

#Chef::Log.info("-------------KKS-------------")

#Chef::Log.info(cmd)

#Chef::Log.info(cmd.stdout)

#Chef::Log.info(cmd.stderr)

x = cmd.stdout.chop

#puts "Value of x : " + x

powershell_script "Install_IIS" do

code <<-EOH

$processLog = 'C:\\Temp\\Chef_PS_Log.txt'

function Date { Get-Date -Format 'yyyy/dd/MM HH:mm:ss' }

Add-Content $processLog (($date=Date) + ' ' + '----- 1-1 Inside

Install_IIS ----')

Add-Content $processLog (($date=Date) + ' ' + 'IIS Server role is not

installed ')

#Install-WindowsFeature -name "Web-Server" -IncludeManagementTools

-IncludeAllSubFeature -WhatIf

Install-WindowsFeature -name "Web-Server" -IncludeManagementTools

-IncludeAllSubFeature

EOH

only_if { x == '1' }

end

I can see here that your goal is to conditionally run this `powershell_script` resource based on the result of your `powershell_out` command. We’re going to add better support for powershell in these not_if/only_if guards in the future, but for now, your best bet is to move evaluation of your powershell script inside the code block you give to `only_if`. Something like

powershell_script “something” do

  # other stuff

  only_if do

    cmd = powershell_out($powershell_code)

    cmd.stdout.chomp == expected_result

  end

end

HTH,
