function Invoke-AACPSRule { <# .EXTERNALHELP Azure.Admin.Console-help.xml .SYNOPSIS Checks your live Azure estate with PSRule for Azure - its Azure Well-Architected Framework rules, the module's own rules and your custom rules - with a console view, objects, and CSV, PDF and interactive HTML reports. .DESCRIPTION Runs PSRule for Azure (the PSRule.Rules.Azure module, 500+ rules) against every resource, resource group and subscription the signed-in account can see, or those in -SubscriptionId. No Az modules: the data PSRule needs - what Export-AzRuleData would export - is read with the Connect-AAC sign-in, from Azure Resource Graph plus the child settings PSRule's rules look at (storage blob services, SQL auditing, Key Vault diagnostic settings, App Service config, API Management APIs and policies, ...). Reader on the subscriptions is enough. The rules that run: PSRule for Azure every rule of the installed PSRule.Rules.Azure (-Baseline picks one of its baselines) Azure.Admin.Console the module's own AAC.* rules (PSRule\Rules): required tags on resources and resource groups, and allowed tag values - each off until its setting is given in -Configuration custom your own PSRule rule files (*.Rule.ps1, *.Rule.yaml, *.Rule.jsonc) from -RulePath -Rule runs only the rules named, and -ExcludeRule leaves rules out; both take names or wildcards ('Azure.Storage.*', 'AAC.*'). -Configuration passes settings to all of them: PSRule for Azure's AZURE_* options and the AAC_* settings. What you get depends on where the command runs: at the prompt a Spectre.Console view: tiles (objects, rules, passed, failed, pass rate), failures by pillar, then a table per pillar with each failing rule, the resources it failed on and why - a page at a time (-NoPaging turns that off) piped onward the AAC.PSRuleResult objects, with no view -PassThru the view and the objects -NoDisplay the objects only Exports: -CsvPath one row per rule and resource (-FailedOnly: failures only) -PdfPath a landscape A4 report: summary and verdict, results by pillar, the failed rules, then every failing resource per rule with the rule's recommendation and documentation link -HtmlPath a self-contained, interactive HTML report: clickable tiles and charts, and every result in one table that opens on the failures, grouped by rule, with search, filters, portal and documentation links and a CSV download When any of them is given, the console shows only the progress and the files written; add -PassThru for the objects too. PSRule runs in a pwsh process of its own, so its YamlDotNet.dll never meets the different versions platyPS, powershell-yaml or Az.Aks may have loaded in this session. A rule that can't evaluate a resource is reported for that resource ("could not evaluate"); every other rule still runs. Settings Reader can't read are listed as warnings, as rules using them may be wrong for those resources. .PARAMETER SubscriptionId Only check these subscriptions. Defaults to every subscription the signed-in account can see. .PARAMETER ResourceType Only check resources of these types, e.g. 'microsoft.storage/*'. Case-insensitive; wildcards work. Resource groups and subscriptions are checked only when no type is given. .PARAMETER Rule Only run these rules: names or wildcards, e.g. 'Azure.KeyVault.*'. .PARAMETER ExcludeRule Leave out these rules: names or wildcards, e.g. 'Azure.Resource.UseTags' or 'AAC.*'. .PARAMETER Baseline A PSRule for Azure baseline, e.g. 'Azure.Pillar.Security' or 'Azure.GA_2024_12'. Defaults to the module's default baseline. .PARAMETER Configuration Settings for the rules: PSRule for Azure's options (e.g. AZURE_RESOURCE_ALLOWED_LOCATIONS) and the AAC_* settings of the module's rules (AAC_REQUIRED_TAGS, AAC_ALLOWED_TAG_VALUES), or your custom rules' own. .PARAMETER RulePath Custom PSRule rule files, or folders of them (*.Rule.ps1, *.Rule.yaml, *.Rule.jsonc), to run with the others. .PARAMETER FailedOnly Return and export only the failures (and rules that couldn't be evaluated). The counts still cover every result. .PARAMETER CsvPath Also write the results to this CSV file. An existing file is overwritten; missing folders are created. .PARAMETER PdfPath Also write a PDF report to this file. Needs Windows and PowerShell 7.4 or later. .PARAMETER HtmlPath Also write an interactive HTML report to this file. .PARAMETER Title The PDF and HTML report's title. Defaults to 'PSRule for Azure'. .PARAMETER PassThru Show the view and also return the AAC.PSRuleResult objects. .PARAMETER NoDisplay Return the objects without showing the view. .PARAMETER NoPaging Show the whole view at once instead of a page at a time. .EXAMPLE Connect-AAC Invoke-AACPSRule Checks every resource you can see and shows what failed. .EXAMPLE Invoke-AACPSRule -SubscriptionId '00000000-0000-0000-0000-000000000000' -HtmlPath .\out\PSRule.html One subscription, as an interactive HTML report. .EXAMPLE Invoke-AACPSRule -CsvPath .\out\PSRule.csv -PdfPath .\out\PSRule.pdf -FailedOnly The failures as a CSV file and a PDF report. .EXAMPLE Invoke-AACPSRule -Rule 'Azure.Storage.*', 'Azure.KeyVault.*' -ExcludeRule 'Azure.Storage.Name' Only the storage and Key Vault rules, without the storage naming rule. .EXAMPLE Invoke-AACPSRule -Baseline 'Azure.Pillar.Security' Only PSRule for Azure's security pillar baseline. .EXAMPLE Invoke-AACPSRule -Configuration @{ AAC_REQUIRED_TAGS = @('Owner', 'CostCenter'); AAC_ALLOWED_TAG_VALUES = @{ Environment = @('prod', 'test', 'dev') }; AZURE_RESOURCE_ALLOWED_LOCATIONS = @('uksouth', 'ukwest') } Adds the module's tag rules and PSRule for Azure's allowed regions. .EXAMPLE Invoke-AACPSRule -RulePath .\MyRules -ExcludeRule 'AAC.*' Runs your own rules from .\MyRules with PSRule for Azure's, without the module's. .EXAMPLE Invoke-AACPSRule -FailedOnly | Group-Object RuleName | Sort-Object Count -Descending | Select-Object -First 10 Count, Name The ten rules that fail most. .OUTPUTS AAC.PSRuleResult (piped onward, or with -PassThru or -NoDisplay) #> [CmdletBinding()] [OutputType('AAC.PSRuleResult')] param( [ValidatePattern('^[0-9a-fA-F]{8}(-[0-9a-fA-F]{4}){3}-[0-9a-fA-F]{12}$')] [string[]] $SubscriptionId, [SupportsWildcards()] [string[]] $ResourceType, [SupportsWildcards()] [string[]] $Rule, [SupportsWildcards()] [string[]] $ExcludeRule, [string] $Baseline, [hashtable] $Configuration = @{}, [string[]] $RulePath, [switch] $FailedOnly, [string] $CsvPath, [string] $PdfPath, [string] $HtmlPath, [string] $Title = 'PSRule for Azure', [switch] $PassThru, [switch] $NoDisplay, [switch] $NoPaging ) # An export means the report is in the files: the console shows only the # title, the progress and the files written. $pipedOnward = $MyInvocation.PipelinePosition -lt $MyInvocation.PipelineLength $interactive = -not $NoDisplay -and -not $pipedOnward $exporting = [bool]($CsvPath -or $PdfPath -or $HtmlPath) $showView = $interactive -and -not $exporting $returnObjects = $PassThru -or $NoDisplay -or $pipedOnward # Resolve paths now, relative to the caller's location, so a bad path # fails before any Azure call. $resolve = { param([string] $Path) if ($Path) { $PSCmdlet.SessionState.Path.GetUnresolvedProviderPathFromPSPath($Path) } } $csvFullPath = & $resolve $CsvPath $pdfFullPath = & $resolve $PdfPath $htmlFullPath = & $resolve $HtmlPath $rulePaths = @(foreach ($path in @($RulePath | Where-Object { $_ })) { $full = & $resolve $path if (-not (Test-Path -LiteralPath $full)) { throw "The rule path '$path' does not exist." } $full }) # Fails with a clear message before anything is drawn. $null = Get-AACAccessToken if ($interactive) { Write-AACRule -Title 'Azure Admin Console :: PSRule for Azure' -Color 'deepskyblue3_1' } $run = Invoke-AACProgress -ScriptBlock { $engine = @{ SubscriptionId = @($SubscriptionId | Where-Object { $_ }) ResourceType = @($ResourceType | Where-Object { $_ }) Rule = @($Rule | Where-Object { $_ }) ExcludeRule = @($ExcludeRule | Where-Object { $_ }) Baseline = $Baseline Configuration = $Configuration RulePath = $rulePaths } Invoke-AACPSRuleEngine @engine } $results = @($run.Results) $listed = if ($FailedOnly) { @($results | Where-Object Outcome -NE 'Pass') } else { $results } # What was checked, for the view and the reports. $scope = [ordered]@{ Subscriptions = if ($SubscriptionId) { $SubscriptionId -join ', ' } else { 'every subscription the account can see' } } if ($ResourceType) { $scope['Resource types'] = $ResourceType -join ', ' } if ($Rule) { $scope['Rules'] = $Rule -join ', ' } if ($ExcludeRule) { $scope['Excluded rules'] = $ExcludeRule -join ', ' } if ($Baseline) { $scope['Baseline'] = $Baseline } if ($RulePath) { $scope['Custom rules'] = $RulePath -join ', ' } if ($Configuration.Count) { $scope['Settings'] = (@($Configuration.Keys | Sort-Object | ForEach-Object { $value = $Configuration[$_] $text = if ($value -is [System.Collections.IDictionary]) { '{' + (@($value.Keys | Sort-Object | ForEach-Object { "$_ = $(@($value[$_]) -join ', ')" }) -join ';
