Loads shipped reference data via Get-VcfCheckSizingReferenceData and brownfield treatment data via Get-VcfCheckBrownfieldTreatmentData, then calculates resource capacity requirements using Get-VcfCheckManagementDomainSizingEstimate. Writes the compressed JSON estimate payload directly to stdout. If an error occurs during module loading, file reading, or estimate calculation, outputs an error message to stderr and exits with code 1. .PARAMETER SelectionsPath Path to a JSON file containing an array of component selection objects (each specifying ComponentKey, SizeKey, NodeCount, and StorageSizeKey). .OUTPUTS Outputs a compressed JSON string containing management domain sizing estimates to stdout. #> [CmdletBinding()] Param ( [Parameter(Mandatory = $true)] [String]$SelectionsPath ) if ($null -ne $PSStyle) { $PSStyle.OutputRendering = 'PlainText' } $envModulePsd1 = ([String]$env:VCFCHECK_MODULE_PSD1).Trim() if (-not [String]::IsNullOrWhiteSpace($envModulePsd1) -and (Test-Path -LiteralPath $envModulePsd1 -PathType Leaf)) { $modulePath = $envModulePsd1 } else { $modulePath = Join-Path -Path (Split-Path -Path $PSScriptRoot -Parent) -ChildPath 'VcfCheck.psd1' } try { Import-Module -Name $modulePath -Force -ErrorAction Stop } catch { Write-Host "ERROR: Could not load the VcfCheck module from `"$modulePath`": $($_.Exception.Message)" -ForegroundColor Red exit 1 } try { $selections = @(Get-Content -LiteralPath $SelectionsPath -Raw -ErrorAction Stop | ConvertFrom-Json -Depth 10 -AsHashtable -ErrorAction Stop) $referenceData = Get-VcfCheckSizingReferenceData $treatmentData = Get-VcfCheckBrownfieldTreatmentData $result = Get-VcfCheckManagementDomainSizingEstimate -Selections $selections -ReferenceData $referenceData -TreatmentData $treatmentData $result | ConvertTo-Json -Depth 10 -Compress } catch { Write-Host "ERROR: $($_.Exception.Message)" -ForegroundColor Red exit 1 } |
