Listens on stdin for JSON-formatted selection payloads, calculates capacity estimates using Get-VcfCheckManagementDomainSizingEstimate, and streams compressed JSON result objects to stdout line-by-line until stdin closes. Writes a 'READY' handshake signal to stdout upon successful initialization to notify calling processes. .OUTPUTS Outputs 'READY' on startup, followed by line-delimited compressed JSON estimate payloads or error objects (`{"error": "<message>"}`) to stdout. #> [CmdletBinding()] Param () 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 $referenceData = Get-VcfCheckSizingReferenceData $treatmentData = Get-VcfCheckBrownfieldTreatmentData } catch { Write-Host "ERROR: Could not start the sizing worker from `"$modulePath`": $($_.Exception.Message)" -ForegroundColor Red exit 1 } [Console]::Out.WriteLine('READY') [Console]::Out.Flush() while ($true) { $line = [Console]::In.ReadLine() if ($null -eq $line) { break } if ([String]::IsNullOrWhiteSpace($line)) { continue } try { $selections = @($line | ConvertFrom-Json -Depth 10 -AsHashtable -ErrorAction Stop) $result = Get-VcfCheckManagementDomainSizingEstimate -Selections $selections -ReferenceData $referenceData -TreatmentData $treatmentData $responseLine = $result | ConvertTo-Json -Depth 10 -Compress } catch { $responseLine = @{ error = $_.Exception.Message } | ConvertTo-Json -Compress } [Console]::Out.WriteLine($responseLine) [Console]::Out.Flush() } |
