function Invoke-AzOpsPush { <# .SYNOPSIS Applies a change to Azure from the AzOps configuration. .DESCRIPTION Applies a change to Azure from the AzOps configuration. .PARAMETER ChangeSet Set of changes from the last execution that need to be applied. .PARAMETER DeleteSetContents Set of content from the deleted files in ChangeSet. .PARAMETER StatePath The root path to where the entire state is being built in. .PARAMETER AzOpsMainTemplate Path to the main template used by AzOps .PARAMETER CustomSortOrder Switch to honor the input ordering for ChangeSet. If not used, ChangeSet will be sorted in ascending order. .EXAMPLE > Invoke-AzOpsPush -ChangeSet changeSet -StatePath $StatePath -AzOpsMainTemplate $templatePath Applies a change to Azure from the AzOps configuration. #> [CmdletBinding(SupportsShouldProcess = $true)] [Alias("Invoke-AzOpsChange")] param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true)] [string[]] $ChangeSet, [Parameter(Mandatory = $false, ValueFromPipeline = $true)] [string[]] $DeleteSetContents, [string] $StatePath = (Get-PSFConfigValue -FullName 'AzOps.Core.State'), [string] $AzOpsMainTemplate = (Get-PSFConfigValue -FullName 'AzOps.Core.MainTemplate'), [switch] $CustomSortOrder ) begin { #region Utility Functions function Resolve-ArmFileAssociation { [CmdletBinding()] param ( [AzOpsScope] $ScopeObject, [string] $FilePath, [string] $AzOpsMainTemplate ) #region Initialization Prep $common = @{ Level = 'Host' Tag = 'pwsh' FunctionName = 'Invoke-AzOpsPush' Target = $ScopeObject } $result = [PSCustomObject] @{ TemplateFilePath = $null TemplateParameterFilePath = $null DeploymentName = $null ScopeObject = $ScopeObject Scope = $ScopeObject.Scope } $fileItem = Get-Item -Path $FilePath if ($fileItem.Extension -notin '.json' , '.bicep') { Write-PSFMessage -Level Warning -String 'Invoke-AzOpsPush.Resolve.NoJson' -StringValues $fileItem.FullName -Tag pwsh -FunctionName 'Invoke-AzOpsPush' -Target $ScopeObject return } #
