PSDsc

Modified on July 26, 2024

Ensures the configuration of a specified PowerShell DSC Resource.

Script usage:

PSDsc(
	[ConfigurationKey: <text>],
	Name: <text>,
	[Module: <text>],
	[Properties: <%(key1: value1, ...)>],
	[PreferWindowsPowerShell: <text>]
);

This operation may be prefixed with PowerShell::, although this is a built-in namespace and isn't really necessary.

Arguments:

NameFormatScript UsageUsage Notes
Otter configuration key
text
ConfigurationKey
The name of the DSC property which will be used as the Otter configuration key for the server. If this is not specified, the "Name" property is used. Default value is "Name".
Resource
text
Name
Value note: "ex: File". This argument is required.
Module
text
Module
Default value is "PSDesiredStateConfiguration".
Properties
%(key1: value1, ...)
Properties
DSC property hashtable as an OtterScript map. Example: %(DestinationPath: C:\hdars\1000.txt, Contents: test file ensured). Value note: "%(...)".
Prefer Windows PowerShell
text
PreferWindowsPowerShell
When true, the script will be run using Windows PowerShell 5.1 where available. When false or on Linux (or on Windows systems without PowerShell 5.1 installed), the script will be run using PowerShell Core instead. Default value is "$PreferWindowsPowerShell".

Note: This is a shorthand version of the Ensure-DscResource operation.

Default Argument: ResourceName: The default argument for this operation is the DSC Resource Name and should follow the format: "ModuleName::ResourceName". If "ModuleName::" is omitted, the PSDesiredStateConfiguration module will be used.

Configuration Key: Otter Specific: By default, Otter will use the Name property of the DSC Resource as the configuration key. If there is no Name property or you would like to override the default configuration key name, specify a property named "Otter_ConfigurationKey" with the value containing a string (or list of strings) indicating the name of the property (or properties) to be used as the unique configuration key.

Note: An argument may be explicitly converted to an integral type by prefixing the value with [type::<typeName>], where <typeName> is one of: int, uint, long, ulong, double, decimal. Normally this conversion is performed automatically and this is not necessary.

Example:


# ensures the existence of a file on the server
PSDsc File (
  Otter_ConfigurationKey: DestinationPath,
  DestinationPath: C:\hdars\1000.txt,
  Contents: test file ensured
);

# runs a custom resource
PSDsc cHdarsResource::cHdars (
  Otter_ConfigurationKey: LocalServer,
  MaximumSessionLength: 1000,
  PortsToListen: @(3322,4431,1123),
  Enabled: true
);
