##Overview

This module adds a new exec provider capable of executing PowerShell commands.

##Module Description

Puppet provides a built-in exec type that is capable of executing commands. This module adds a powershell provider to the exec type, which enables exec parameters, listed below. This module is particularly helpful if you need to run PowerShell commands but don't know the details about how PowerShell is executed, since you can technically run PowerShell commands in Puppet without the module.

##Setup

###Setup Requirements This module requires PowerShell to be installed and the powershell.exe to be available in the system PATH.

###Beginning with powershell

The powershell module adapts the Puppet exec resource to run PowerShell commands. To get started, simply install the module and declare 'powershell' in provider with the applicable command.

    exec { 'RESOURCENAME':
      command   => '$(SOMECOMMAND)',
      provider  => powershell,
    }

##Usage

When using exec resources with the powershell provider, the command parameter must be single-quoted to prevent Puppet from interpolating $(..).

For instance, if you wanted to rename the Guest account:

    exec { 'rename-guest':
      command   => '$(Get-WMIObject Win32_UserAccount -Filter "Name=\'guest\'").Rename("new-guest")',
      unless    => 'if (Get-WmiObject Win32_UserAccount -Filter "Name=\'guest\'") { exit 1 }',
      provider  => powershell,
    }

Note that the example uses the unless parameter to make the resource idempotent. The command is only executed if the Guest account does not exist, as indicated by unless returning 0.

Note: PowerShell variables (e.g. $_), must be escaped in Puppet manifests either using backslashes or single quotes.

Alternatively, you can put the PowerShell code for the command, onlyif, and unless parameters into separate templates and then invoke the template function in the resource.

exec { 'rename-guest':
  command   => template('guest/rename-guest.ps1'),
  onlyif    => template('guest/guest-exists.ps1'),
  provider  => powershell,
  logoutput => true,
}

Each template is a PowerShell script.

$obj = $(Get-WMIObject Win32_UserAccount -Filter "Name='Guest'")
$obj.Rename("OtherGuest")

This has the added benefit of not requiring escaping '$' in the PowerShell code.

If you specify 'on_failure', it only logs the output when the command has an exit code that does not match any value specified by the returns attribute. Valid options: 'true', 'false', and 'on_failure'. Default: 'on_failure'.

#####onlyif Runs the exec only if the command returns 0. Valid options: String. Default: Undefined.

#####path Specifies the search path used for command execution. Valid options: String of the path, an array, or a semicolon-separated list. Default: Undefined.

#####returns Lists the expected return code(s). An error will be returned if the executed command returns something else. Valid options: An array of acceptable return codes or a single value. Default: 0.

#####timeout Sets the maximum time in seconds that the command should take. Valid options: Number or string representation of a number. Default: 300.

#####tries Determines the number of times execution of the command should be attempted. Valid options: Number or a string representation of a number. Default: '1'.

##Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our module contribution guide.
