Invoke-DscResource

  • Reference
Module:
PSDesiredStateConfiguration

Runs a method of a specified DSC resource.

Syntax

Invoke-DscResource
      [-Name] <String>
      [-Method] <String>
      -ModuleName <ModuleSpecification>
      -Property <Hashtable>
      [<CommonParameters>]

Description

The Invoke-DscResource cmdlet runs a method of a specified Windows PowerShell Desired State Configuration (DSC) resource. Before you run this cmdlet, set the refresh mode of the Local Configuration Manager (LCM) to Disabled.

This cmdlet invokes a DSC resource directly, without creating a configuration document. Using this cmdlet, configuration management products can manage windows by using DSC resources. This cmdlet also enables debugging of resources when the DSC engine or LCM is running with debugging enabled.

This cmdlet doesn't work with composite resources. Composite resources are parameterized configurations. Using composite resources requires the LCM.

Examples

Example 1: Invoke the Set method of a resource by specifying its mandatory properties

Invoke-DscResource -Name Log -Method Set -Property @{Message = 'Hello World'} -ModuleName PSDesiredStateConfiguration

This command invokes the Set method of a resource named Log and specifies a Message property for it.

Example 2: Invoke the Test method of a resource for a specified module

Invoke-DscResource -Name WindowsProcess -Method Test -Property @{Path = 'C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe'; Arguments = ''} -ModuleName PSDesiredStateConfiguration

This command invokes the Test method of a resource named WindowsProcess, which is in the module named PSDesiredStateConfiguration.
