function New-AzureLocalFleetStatusHtmlReport { <# .SYNOPSIS Generates a self-contained HTML report of fleet update status. .DESCRIPTION Collects update status data from Azure Local clusters and generates a standalone HTML report suitable for email, SharePoint, or offline viewing. The report includes executive summary cards, a progress bar, cluster status table with color-coded badges, and optional sections for health check failures and update run history. Data is collected using the module's existing functions: - Get-AzureLocalClusterInventory (cluster list and UpdateRing tags) - Get-AzureLocalClusterUpdateReadiness (health state, readiness) - Get-AzureLocalUpdateSummary (current update versions) - Get-AzureLocalAvailableUpdates (pending updates) - Get-AzureLocalUpdateRuns (recent update history, optional) - Test-AzureLocalClusterHealth (detailed health checks, optional) .PARAMETER ClusterResourceIds An array of full Azure Resource IDs for the clusters to include in the report. .PARAMETER ClusterNames An array of Azure Local cluster names to include in the report. .PARAMETER ScopeByUpdateRingTag Find clusters by their 'UpdateRing' tag value via Azure Resource Graph. .PARAMETER UpdateRingValue The value of the 'UpdateRing' tag to match when using -ScopeByUpdateRingTag. .PARAMETER ResourceGroupName Resource group containing the clusters (only used with -ClusterNames). .PARAMETER SubscriptionId Azure subscription ID (defaults to current subscription). .PARAMETER AllClusters Discovers all Azure Local clusters via Azure Resource Graph and includes them in the report. By default, no cap is applied - every discovered cluster is included. Use -MaxClusters to limit the number of clusters returned (e.g. for targeted runs or to avoid large fan-out). Uses the current Azure CLI subscription context. .PARAMETER MaxClusters Optional cap on clusters included when -AllClusters is used. Default 0 (no cap). Set to a positive integer (1-100000) to limit the fleet slice. Has no effect for other parameter sets. .PARAMETER OutputPath File path for the HTML report output. Required. .PARAMETER IncludeUpdateRuns Include recent update run history section in the report. .PARAMETER IncludeHealthDetails Include detailed health check failure section in the report. .PARAMETER Title Custom report title. Auto-generated if not specified: single cluster = '<ClusterName> - Update Status Report', multiple clusters = 'Azure Local Fleet Update Status Report'. .PARAMETER PassThru Returns the HTML content as a string in addition to writing the file. .OUTPUTS System.String - HTML content (only when -PassThru is specified). .EXAMPLE New-AzureLocalFleetStatusHtmlReport -AllClusters -OutputPath "C:\Reports\fleet-all.html" Generates an HTML report for all clusters (up to 100) across the subscription. .EXAMPLE New-AzureLocalFleetStatusHtmlReport -ScopeByUpdateRingTag -UpdateRingValue "Wave1" -OutputPath "C:\Reports\wave1-status.html" Generates an HTML report for all Wave1 clusters. .EXAMPLE New-AzureLocalFleetStatusHtmlReport -ClusterNames @("Cluster01","Cluster02") -OutputPath "C:\Reports\fleet.html" -IncludeHealthDetails -IncludeUpdateRuns Generates a full report with health details and update run history. .EXAMPLE $html = New-AzureLocalFleetStatusHtmlReport -ScopeByUpdateRingTag -UpdateRingValue "Production" -OutputPath "C:\Reports\prod.html" -PassThru Generates the report and also captures the HTML string for further use (e.g., email body). #> [CmdletBinding(DefaultParameterSetName = 'All', SupportsShouldProcess = $true, ConfirmImpact = 'Low')] [OutputType([string])] param( [Parameter(Mandatory = $true, ParameterSetName = 'ByResourceId')] [string[]]$ClusterResourceIds, [Parameter(Mandatory = $true, ParameterSetName = 'ByName')] [string[]]$ClusterNames, [Parameter(Mandatory = $true, ParameterSetName = 'ByTag')] [switch]$ScopeByUpdateRingTag, [ValidatePattern('^[A-Za-z0-9_-]{1,64}$')] [Parameter(Mandatory = $true, ParameterSetName = 'ByTag')] [string]$UpdateRingValue, [Parameter(Mandatory = $false, ParameterSetName = 'All')] [switch]$AllClusters, [Parameter(Mandatory = $false, ParameterSetName = 'ByName')] [string]$ResourceGroupName, [Parameter(Mandatory = $false, ParameterSetName = 'ByName')] [string]$SubscriptionId, [Parameter(Mandatory = $true)] [ValidateScript({ $parent = Split-Path $_ -Parent if ($parent -and -not (Test-Path $parent)) { # Check if the drive at least exists $drive = Split-Path $_ -Qualifier -ErrorAction SilentlyContinue if ($drive -and -not (Test-Path $drive)) { throw "Drive '$drive' does not exist.
