If an application already exists at that path, it is removed first. The application can run under a custom application pool using the optional `AppPoolName` parameter. If no app pool is specified, the application runs under the same app pool as the website it runs under. .EXAMPLE Install-IisApplication -SiteName Peanuts -VirtualPath CharlieBrown -PhysicalPath C:\Path\To\CharlieBrown -AppPoolName CharlieBrownPool Creates an application at `Peanuts/CharlieBrown` which runs from `Path/To/CharlieBrown`. The application runs under the `CharlieBrownPool`. .EXAMPLE Install-IisApplication -SiteName Peanuts -VirtualPath Snoopy -PhysicalPath C:\Path\To\Snoopy Create an application at Peanuts/Snoopy, which runs from C:\Path\To\Snoopy. It uses the same application as the Peanuts website. #> [CmdletBinding()] param( [Parameter(Mandatory=$true)] [string] # The site where the application should be created. $SiteName, [Parameter(Mandatory=$true)] [Alias('Name')] [string] # The name of the application. $VirtualPath, [Parameter(Mandatory=$true)] [Alias('Path')] [string] # The path to the application. $PhysicalPath, [string] # The app pool for the application. $AppPoolName ) $PhysicalPath = Resolve-FullPath -Path $PhysicalPath if( -not (Test-Path $PhysicalPath -PathType Container) ) { $null = New-Item $PhysicalPath -ItemType Directory } $appPoolDesc = '' if( $AppPoolName ) { $appPoolDesc = '; appPool: {0}' -f $AppPoolName } $app = Get-IisApplication -SiteName $SiteName -VirtualPath $VirtualPath if( $app ) { Write-Verbose ('IIS://{0}: deleting application' -f (Join-IisVirtualPath $SiteName $VirtualPath)) $app.Delete() $app.CommitChanges() } Write-Verbose ('IIS:/{0}: creating application: physicalPath: {1}{2}' -f (Join-IisVirtualPath $SiteName $VirtualPath),$PhysicalPath,$appPoolDesc) $site = Get-IisWebsite -SiteName $SiteName if( -not $site ) { Write-Error ('[IIS] Website ''{0}'' not found.' -f $SiteName) return } $apps = $site.GetCollection() $app = $apps.CreateElement('application') | Add-IisServerManagerMember -ServerManager $site.ServerManager -PassThru $app['path'] = "/{0}" -f $VirtualPath $apps.Add( $app ) | Out-Null if( $AppPoolName ) { $app['applicationPool'] = $AppPoolName } $vdir = $app.VirtualDirectories | Where-Object { $_.Path -eq '/' } if( -not $vdir ) { $vdirs = $app.GetCollection() $vdir = $vdirs.CreateElement('virtualDirectory') $vdir['path'] = '/' $vdirs.Add( $vdir ) | Out-Null } $vdir['physicalPath'] = $PhysicalPath $app.CommitChanges() } |
