<# .SYNOPSIS Update ARM template from another ARM template. .DESCRIPTION Update an ARM template, with the content of another ARM template. You can update the entire ARM template, or just a part of it. Supports the following options: * Full * SkipResources * SkipParameters .PARAMETER Source The path to the source ARM template to be used as the changes you want to apply. .PARAMETER Destination The path to the destination ARM template to be updated. .PARAMETER SkipParameters If true, then the parameters will not be updated. .PARAMETER SkipResources If true, then the resources will not be updated. .PARAMETER RemoveSource If true, then the source ARM template will be removed after it has been used. .EXAMPLE PS C:\> Update-PsLaArmTemplate -Source C:\Temp\Source.json -Destination C:\Temp\Destination.json This will update the ARM template in C:\Temp\Destination.json from the ARM template in C:\Temp\Source.json. It will overwrite the entire ARM template, but will not remove the source ARM template. .EXAMPLE PS C:\> Update-PsLaArmTemplate -Source C:\Temp\Source.json -Destination C:\Temp\Destination.json -SkipParameters This will update the ARM template in C:\Temp\Destination.json from the ARM template in C:\Temp\Source.json. It will overwrite the entire ARM template, but leave the parameters alone. .EXAMPLE PS C:\> Update-PsLaArmTemplate -Source C:\Temp\Source.json -Destination C:\Temp\Destination.json -SkipResources This will update the ARM template in C:\Temp\Destination.json from the ARM template in C:\Temp\Source.json. It will overwrite the entire ARM template, but leave the resources alone. .EXAMPLE PS C:\> Update-PsLaArmTemplate -Source C:\Temp\Source.json -Destination C:\Temp\Destination.json -RemoveSource This will update the ARM template in C:\Temp\Destination.json from the ARM template in C:\Temp\Source.json. It will overwrite the entire ARM template, and remove the source ARM template. .NOTES Author: Mötz Jensen (@Splaxi) #> function Update-PsLaArmTemplate { [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseShouldProcessForStateChangingFunctions', '')] [CmdletBinding()] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [PsfValidateScript('PSFramework.Validate.FSPath.File', ErrorString = 'PSFramework.Validate.FSPath.File')] [string] $Source, [parameter(Mandatory = $true)] [PsfValidateScript('PSFramework.Validate.FSPath.File', ErrorString = 'PSFramework.Validate.FSPath.File')] [string] $Destination, [switch] $SkipParameters, [switch] $SkipResources, [switch] $RemoveSource ) process { #The task counter needs to be reset prior running Set-PSFConfig -FullName PsLogicAppExtractor.Execution.TaskCounter -Value 0 Set-PSFConfig -FullName PsLogicAppExtractor.Execution.TaskInputNext -Value "" Set-PSFConfig -FullName PsLogicAppExtractor.Execution.TaskOutputFile -Value "" Set-PSFConfig -FullName PsLogicAppExtractor.Execution.TaskPath -Value "" Set-PSFConfig -FullName PsLogicAppExtractor.Execution.Name -Value "" $armObjSource = Get-TaskWorkObject -Path $Source $armObjDestination = Get-TaskWorkObject -Path $Destination if (-not $SkipParameters) { $armObjDestination.parameters = $armObjSource.parameters | ConvertTo-Json -Depth 10 | ConvertFrom-Json -Depth 10 } if (-not $SkipResources) { $armObjDestination.resources = @($armObjSource.resources | ConvertTo-Json -Depth 100 | ConvertFrom-Json -Depth 100) } Out-TaskFile -Path $Destination -InputObject $([ArmTemplate]$armObjDestination) if ($RemoveSource) { Remove-Item -Path $Source -Force -Recurse -ErrorAction SilentlyContinue } } } |
