The puppet agent on my Windows VMs is not running a powershell script. I have tested it with a very simple script as well. The script is stored on C drive as test.ps1. Its contents are as follows:-

"$(Get-Date -format F)" | Out-File C:\z.txt -Encoding ASCII

When I run this as ./test.ps1 from the powershell it works fine and the file z.txt is created. But for some reason puppet doesn't run this. The contents of my site.pp are:-

exec { "Run Script":
        command => 'C:/Windows/System32/WindowsPowerShell/v1.0/powershell.exe -Executionpolicy Unrestricted -File c:/test.ps1',
        logoutput => true,
        refreshonly => true,
}

And the output of "puppet agent -t" from the VM itself is:-

C:\Users\Administrator>puppet agent -t
Info: Retrieving pluginfacts
Warning: Copying owner/mode/group from the source file on Windows is deprecated;
 use source_permissions => ignore.
   (at C:/Program Files (x86)/Puppet Labs/Puppet/puppet/lib/puppet/type/file/sou

Info: Applying configuration version '1410182959'
Notice: Finished catalog run in 0.42 seconds

So it seems to me that there is no error anywhere but still the powershell script doesn't run. Any ideas what am I doing wrong?

  1. Have you tried using the Puppetlabs supported powershell provider for exec?
  2. The refreshonly attribute means it will only process that resource if another resource is modified. It doesn't appear that it depends on anything else, or perhaps you haven't posted all of the relevant manifests.

  • Definitely use the PowerShell module on the forge -> https://forge.puppetlabs.com/puppetla...
  • Always try to ensure idempotency when running a powershell script by supplying an unless or onlyif - https://docs.puppetlabs.com/references/latest/type.html#exec-attribute-unless
  • Note that the module will work properly on both 32-bit and 64-bit Windows, whereas the exec method that you're using can behave differently on Puppet 32-bit or Puppet 64-bit (first introduced in Puppet 3.7)
