This module contains DSC resources for the management and configuration of Microsoft Internet Information Services (IIS).

This project has adopted this Code of Conduct.

For each merge to the branch main a preview release will be deployed to PowerShell Gallery. Periodically a release version tag will be pushed which will deploy a full release to PowerShell Gallery.

Please check out common DSC Community contributing guidelines.

A full list of changes in each version can be found in the change log.

The documentation can be found in the WebAdministration Wiki. The DSC resources schema files is used to automatically update the documentation on each PR merge.

You can review the Examples directory in the WebAdministration module for some general use scenarios for all of the resources that are in the module.

The resource examples are also available in the WebAdministration Wiki.

To manually install the module, download the source code from GitHub and unzip the contents to the '$env:ProgramFiles\WindowsPowerShell\Modules' folder.

To install from the PowerShell gallery using PowerShellGet (in PowerShell 5.0) run the following command:

Find-Module -Name WebAdministrationDsc | Install-Module

To confirm installation, run the below command and ensure you see the DSC resources available:

Get-DscResource -Module WebAdministrationDsc

The minimum Windows Management Framework (PowerShell) version required is 4.0 or higher.

Note: In the CI pipeline the resource are only tested on PowerShell 5.1, so PowerShell 4.0 support is best effort as this time.

You can review the Examples directory in the WebAdministrationDsc module for some general use scenarios for all of the resources that are in the module.

When configuring an IIS Application that uses PHP, you first need to register the PHP CGI module with IIS. The following xPhp configuration downloads and installs the prerequisites for PHP, downloads PHP, registers the PHP CGI module with IIS and sets the system environment variable that PHP needs to run.

Note: This example is intended to be used as a composite resource, so it does not use Configuration Data. Please see the Composite Configuration Blog on how to use this configuration in another configuration.
