xPSDesiredStateConfiguration

The xPSDesiredStateConfiguration module is a more recent, experimental version of the PSDesiredStateConfiguration module that ships in Windows as part of PowerShell 4.0.

The high quality, supported version of this module is available as PSDscResources.

This module is automatically tested using PowerShell 5.1 on servers running Windows 2012 R2 and Windows 2016, and is expected to work on other operating systems running PowerShell 5.1. While this module may work with PowerShell versions going back to PowerShell 4, there is no automatic testing performed for these versions, and thus no guarantee that the module will work as expected.

This project has adopted this code of conduct.

xArchive

Provides a mechanism to expand an archive (.zip) file to a specific path or remove an expanded archive (.zip) file from a specific path on a target node.

Requirements

  • The System.IO.Compression type assembly must be available on the machine.
  • The System.IO.Compression.FileSystem type assembly must be available on the machine.

Parameters

  • [String] Path (Key): The path to the archive file that should be expanded to or removed from the specified destination.
  • [String] Destination (Key): The path where the specified archive file should be expanded to or removed from.
  • [String] Ensure (Write): Specifies whether or not the expanded content of the archive file at the specified path should exist at the specified destination. To update the specified destination to have the expanded content of the archive file at the specified path, specify this property as Present. To remove the expanded content of the archive file at the specified path from the specified destination, specify this property as Absent. The default value is Present. { Present | Absent }.
  • [Boolean] Validate (Write): Specifies whether or not to validate that a file at the destination with the same name as a file in the archive actually matches that corresponding file in the archive by the specified checksum method. If the file does not match and Ensure is specified as Present and Force is not specified, the resource will throw an error that the file at the desintation cannot be overwritten. If the file does not match and Ensure is specified as Present and Force is specified, the file at the desintation will be overwritten. If the file does not match and Ensure is specified as Absent, the file at the desintation will not be removed. The default Checksum method is ModifiedDate. The default value is false.
  • [String] Checksum (Write): The Checksum method to use to validate whether or not a file at the destination with the same name as a file in the archive actually matches that corresponding file in the archive. An invalid argument exception will be thrown if Checksum is specified while Validate is specified as false. ModifiedDate will check that the LastWriteTime property of the file at the destination matches the LastWriteTime property of the file in the archive. CreatedDate will check that the CreationTime property of the file at the destination matches the CreationTime property of the file in the archive. SHA-1, SHA-256, and SHA-512 will check that the hash of the file at the destination by the specified SHA method matches the hash of the file in the archive by the specified SHA method. The default value is ModifiedDate. { ModifiedDate | CreatedDate | SHA-1 | SHA-256 | SHA-512 }
  • [System.Management.Automation.PSCredential] Credential (Write): The credential of a user account with permissions to access the specified archive path and destination if needed.
  • [Boolean] Force (Write): Specifies whether or not any existing files or directories at the destination with the same name as a file or directory in the archive should be overwritten to match the file or directory in the archive. When this property is false, an error will be thrown if an item at the destination needs to be overwritten. The default value is false.

Examples

xDscWebService

  • EndpointName: The desired web service name.
  • CertificateThumbPrint: Certificate thumbprint for creating an HTTPS endpoint. Use "AllowUnencryptedTraffic" for setting up a non SSL based endpoint.
  • Port: Port for web service.
  • ApplicationPoolName: The name of IIS ApplicationPool to use for the Pull Server. If not specified a pool with name 'PSWS' will be created and bound to the Pull Server instance. Preferably the new application pool is created by using the xWebAppPool resource from the xWebAdministration DSC module
  • PhysicalPath: Folder location where the content of the web service resides.
  • Ensure: Ensures that the web service is Present or Absent
  • State: State of the web service: { Started | Stopped }
  • ModulePath: Folder location where DSC resources are stored.
  • ConfigurationPath: Folder location where DSC configurations are stored.
  • RegistrationKeyPath: Folder location where DSC pull server registration key file is stored.
  • AcceptSelfSignedCertificates: Whether self signed certificate can be used to setup pull server.
  • UseSecurityBestPractices: Whether to use best practice security settings for the node where pull server resides on. Caution: Setting this property to $true will reset registry values under "HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL". This environment change enforces the use of stronger encryption cypher and may affect legacy applications. More information can be found at https://support.microsoft.com/en-us/kb/245030 and https://technet.microsoft.com/en-us/library/dn786418(v=ws.11).aspx.
  • DisableSecurityBestPractices: The items that are excepted from following best practice security settings.
  • Enable32BitAppOnWin64: When this property is set to true, Pull Server will run on a 32 bit process on a 64 bit machine.
  • ConfigureFirewall: When this property is set to true, a Windows Firewall rule will be created, which allows incoming HTTP traffic for the selected Port. Default: true

Remark:

Configuring a Windows Firewall rule (exception) for a DSC Pull Server instance by using the xDscWebService resource is considered deprecated and thus will be removed in the future.

DSC will issue a warning when the ConfigureFirewall property is set to true. Currently the default value is true to maintain backwards compatibility with existing configurations. At a later time the default value will be set to false and in the last step the support to create a firewall rule using xDscWebService will be removed.

All users are requested to adjust existing configurations so that the ConfigureFirewall is set to false and a required Windows Firewall rule is created by using the Firewall resource from the NetworkingDsc module.
