Build status

xWebAdministration

The xWebAdministration module contains the xIisModule, xWebAppPool, xWebsite, xWebApplication, xWebVirtualDirectory, and xWebConfigKeyValue DSC resources for creating and configuring various IIS artifacts.

Contributing

Please check out common DSC Resources contributing guidelines.

Resources

xIISModule

  • Name: The logical name to register the module as in IIS.
  • RequestPath: The allowed request paths, such as *.php
  • Verb: An array of allowed verbs, such as get and post.

  • Ensure: Ensures that the module is Present or Absent.

xWebAppPool

  • Name : Indicates the application pool name. The value must contain between 1 and 64 characters.
  • Ensure : Indicates if the application pool exists. Set this property to Absent to ensure that the application pool does not exist. Setting it to Present (the default value) ensures that the application pool exists.
  • State : Indicates the state of the application pool. The values that are allowed for this property are: Started, Stopped.
  • autoStart : When set to $true, indicates to the World Wide Web Publishing Service (W3SVC) that the application pool should be automatically started when it is created or when IIS is started.

Examples

Registering PHP

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.

Stopping the default website

When configuring a new IIS server, several references recommend removing or stopping the default website for security purposes. This example sets up your IIS web server by installing IIS Windows Feature. After that, it will stop the default website by setting State = Stopped.

Configuration Sample_xWebsite_StopDefault
{
    param
    (
        # Target nodes to apply the configuration
        [string[]]$NodeName = 'localhost'
    )
    # Import the module that defines custom resources
    Import-DscResource -Module xWebAdministration
    Node $NodeName
    {
        # Install the IIS role
        WindowsFeature IIS
        {
            Ensure          = "Present"
            Name            = "Web-Server"
        }
        # Stop the default website
        xWebsite DefaultSite
        {
            Ensure          = "Present"
            Name            = "Default Web Site"
            State           = "Stopped"
            PhysicalPath    = "C:\inetpub\wwwroot"
            DependsOn       = "[WindowsFeature]IIS"
        }
    }
}

Create a new website

While setting up IIS and stopping the default website is interesting, it isn’t quite useful yet. After all, people typically use IIS to set up websites of their own with custom protocol and bindings. Fortunately, using DSC, adding another website is as simple as using the File and xWebsite resources to copy the website content and configure the website.

Configuration Sample_xWebsite_NewWebsite
{
    param
    (
        # Target nodes to apply the configuration
        [string[]]$NodeName = 'localhost',
        # Name of the website to create
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [String]$WebSiteName,
        # Source Path for Website content
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [String]$SourcePath,
        # Destination path for Website content
        [Parameter(Mandatory)]
        [ValidateNotNullOrEmpty()]
        [String]$DestinationPath
    )

    # Import the module that defines custom resources
    Import-DscResource -Module xWebAdministration
    Node $NodeName
    {
        # Install the IIS role
        WindowsFeature IIS
        {
            Ensure          = "Present"
            Name            = "Web-Server"
        }

        # Install the ASP .NET 4.5 role
        WindowsFeature AspNet45

Creating the default website using configuration data

In this example, we’ve moved the parameters used to generate the website into a configuration data file. All of the variant portions of the configuration are stored in a separate file. This can be a powerful tool when using DSC to configure a project that will be deployed to multiple environments. For example, users managing larger environments may want to test their configuration on a small number of machines before deploying it across many more machines in their production environment.

Configuration files are made with this in mind. This is an example configuration data file (saved as a .psd1).
