Function New-PuppetDscModule { <# .SYNOPSIS Puppetize a PowerShell module with DSC resources .DESCRIPTION This function builds a Puppet Module which wraps and calls PowerShell DSC resources via the Puppet resource_api. This module: - Includes a base resource_api provider which relies on ruby-pwsh and knows how to invoke DSC resources - Includes a type for each DSC resource, pulling in the appropriate metadata including help, default value and mandatory status, as well as whether or not it includes an embedded mof. - Allows for the tracking of changes on a property-by-property basis while using DSC and Puppet together .PARAMETER PowerShellModuleName The name of the PowerShell module on the gallery which has DSC resources you want to Puppetize .PARAMETER PowerShellModuleVersion The version of the PowerShell module on the gallery which has DSC resources you want to Puppetize. If left blank, will default to latest available. .PARAMETER PuppetModuleName The name of the Puppet module for the wrapper; if not specified, will default to the downcased name of the module to adhere to Puppet naming conventions. .PARAMETER PuppetModuleAuthor The name of the Puppet module author; if not specified, will default to your PDK configuration's author. .PARAMETER OutputDirectory The folder in which to build the Puppet module. Defaults to a folder called import in the current location. .PARAMETER PassThru If specified, the function returns the path to the root folder of the Puppetized module on the filesystem. .PARAMETER Confirm Prompts for confirmation before creating the Puppet module .PARAMETER WhatIf Shows what would happen if the function runs. .PARAMETER Repository Specifies a non-default PSRepository. If left blank, will default to PSGallery. .EXAMPLE New-PuppetDscModule -PowerShellModuleName PowerShellGet -PowerShellModuleVersion 2.2.3 -Repository PSGallery This function will create a new Puppet module, powershellget, which vendors and puppetizes the PowerShellGet PowerShell module at version 2.2.3 and its dependencies, exposing the DSC resources as Puppet resources. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'Medium')] param( [Parameter(Mandatory=$True)] [string]$PowerShellModuleName, [string]$PowerShellModuleVersion, [string]$PuppetModuleName, [string]$PuppetModuleAuthor, [string]$OutputDirectory, [switch]$PassThru, [string]$Repository ) Begin { # Unless specified, use a valid Puppet module name If ([string]::IsNullOrEmpty($PuppetModuleName)) { $PuppetModuleName = Get-PuppetizedModuleName -Name $PowerShellModuleName } Else { $PuppetizedName = Get-PuppetizedModuleName -Name $PuppetModuleName if ($PuppetizedName -ne $PuppetModuleName) { Throw "Invalid puppet module name '$PuppetModuleName' specified; must include only lowercase letters, digits, and underscores and not start with a digit" } } # If specified, canonicalize the Puppet module author name If (![string]::IsNullOrEmpty($PuppetModuleAuthor)) { $PuppetModuleAuthor = ConvertTo-CanonicalPuppetAuthorName -AuthorName $PuppetModuleAuthor } # Default to the `import` folder in the current path If ([string]::IsNullOrEmpty($OutputDirectory)) { $OutputDirectory = Join-Path -Path (Get-Location) -ChildPath 'import' } Else {} # make sure that we're operating on a absolute path to avoid confusion from symlinks and relative paths $OutputDirectory = New-Item -Path $OutputDirectory -ItemType "directory" -Force $PuppetModuleRootFolderDirectory = Join-Path -Path $OutputDirectory -ChildPath $PuppetModuleName $VendoredDscResourcesDirectory = Join-Path -Path $OutputDirectory -ChildPath "$PuppetModuleName/lib/puppet_x/dsc_resources" $PuppetModuleTypeDirectory = Join-Path -Path $PuppetModuleRootFolderDirectory -ChildPath 'lib/puppet/type' $PuppetModuleProviderDirectory = Join-Path -Path $PuppetModuleRootFolderDirectory -ChildPath 'lib/puppet/provider' $InitialPSModulePath = $Env:PSModulePath $InitialErrorActionPreference = $ErrorActionPreference If (!(Test-RunningElevated)) { Write-PSFMessage -Message 'Running un-elevated: will not be able to parse embedded CIM instances; run again with Administrator permissions to map embedded CIM instances' -Level Warning } Else { If (Test-SymLinkedItem -Path $OutputDirectory -Recurse) { Stop-PsfFunction -EnableException $true -Message "The specified output folder '$OutputDirectory' has a symlink in the path; CIM class parsing will not work in a symlinked folder, specify another path" } } } Process { $ShouldProcessMessage = "Puppetize the '$PowerShellModuleName' module" If (![string]::IsNullOrEmpty($PowerShellModuleVersion)) { $ShouldProcessMessage += " at version '$PowerShellModuleVersion'"} If ([string]::IsNullOrEmpty($Repository)) { $Repository = "PSGallery"} If ($PSCmdlet.ShouldProcess($OutputDirectory, $ShouldProcessMessage)) { Try { $ErrorActionPreference = 'Stop' # Scaffold the module via the PDK Write-PSFMessage -Message 'Initializing the Puppet Module' Initialize-PuppetModule -OutputFolderPath $OutputDirectory -PuppetModuleName $PuppetModuleName -verbose # Vendor the PowerShell module and all of its dependencies Write-PSFMessage -Message 'Vendoring the DSC Resources' Add-DscResourceModule -Name $PowerShellModuleName -Path $VendoredDscResourcesDirectory -RequiredVersion $PowerShellModuleVersion -Repository $Repository # Update the Puppet module metadata Write-PSFMessage -Message 'Updating the Puppet Module metadata' $PowerShellModuleManifestPath = (Resolve-Path -Path "$VendoredDscResourcesDirectory/$PowerShellModuleName/$PowerShellModuleName.psd1") $MetadataParameters = @{ PuppetModuleFolderPath = $PuppetModuleRootFolderDirectory PowerShellModuleManifestPath = $PowerShellModuleManifestPath PuppetModuleAuthor = $PuppetModuleAuthor } Update-PuppetModuleMetadata @MetadataParameters # Update the Puppet module test fixtures Write-PSFMessage -Message 'Updating the Puppet Module test fixtures' Update-PuppetModuleFixture -PuppetModuleFolderPath $PuppetModuleRootFolderDirectory # Write the Puppet module README Write-PSFMessage -Message 'Writing the Puppet Module readme' Update-PuppetModuleReadme -PuppetModuleFolderPath $PuppetModuleRootFolderDirectory -PowerShellModuleManifestPath $PowerShellModuleManifestPath # The PowerShell Module path needs to be munged because the Get-DscResource function always and only # checks the PSModulePath for DSC modules; you CANNOT point to a module by path.
