Parameters

• tag parameter is purely informative and has no impact on the resource.
• ResourceName must be the explicit name of the DSC resource you wish to apply
• ScriptBlock must be a powershell script in plain text, returning an Hashtable containing the parameters to pass to the resource.

Note that this method can only apply built-in Windows resources. It will not be able to apply an external resource.

Example

If we want to apply a Registry resource. The resourceName used will be Registry And a potential ScriptBlock could be:

 $HKLM_SOFT="HKEY_LOCAL_MACHINE\SOFTWARE"
 $Ensure      = "Present"
 $Key         = $HKLM_SOFT + "\ExampleKey"

 $table = @{}
 $table.Add("Ensure", $Ensure)
 $table.Add("Key", $Key)
 $table.Add("ValueName", "RudderTest")
 $table.Add("ValueData", "TestData")
 $table

Note that all the ScriptBlock will be readable on the Rudder logs or in the policy files.
