.Synopsis Get (or create) a PSSession for a NAV/BC Container .Description Checks the session cache for an existing session. If a session exists, it will be reused. If no session exists, a new session will be created. .Parameter containerName Name of the container for which you want to create a session .Parameter silent Include the silent switch to avoid the welcome text .Example $session = Get-BcContainerSession -containerName bcserver PS C:\>Invoke-Command -Session $session -ScriptBlock { Set-NavServerInstance -ServerInstance $ServerInstance -restart } #> function Get-BcContainerSession { [CmdletBinding()] Param ( [string] $containerName = $bcContainerHelperConfig.defaultContainerName, [switch] $tryWinRmSession = ($bccontainerHelperConfig.useWinRmSession -ne 'never'), [switch] $alwaysUseWinRmSession = ($bccontainerHelperConfig.useWinRmSession -eq 'always'), [switch] $usePwsh = $bccontainerHelperConfig.usePwshForBc24, [switch] $silent, [switch] $reinit ) Process { $newsession = $false $session = $null $inspect = docker inspect $containerName | ConvertFrom-Json if (!($inspect.Config.Labels.psobject.Properties.Name -eq 'maintainer' -and $inspect.Config.Labels.maintainer -eq "Dynamics SMB")) { throw "Container $containerOrImageName is not a NAV/BC container" } [System.Version]$platformVersion = [System.Version]"$($inspect.Config.Labels.platform)" if ($inspect.Config.Labels.PSObject.Properties.Name -eq 'filesonly' -and $inspect.Config.Labels.filesonly -eq 'yes') { $tryWinRmSession = 'never' } if ($platformVersion.Major -lt 24) { $usePwsh = $false } $configurationName = 'Microsoft.PowerShell' if ($usePwsh) { $configurationName = 'PowerShell.7' } $cacheName = "$containerName-$configurationName" if ($sessions.ContainsKey($cacheName)) { if ($bcContainerHelperConfig.debugMode) { Write-Host "Session $cacheName found in cache" } $session = $sessions[$cacheName] try { Invoke-Command -Session $session -ScriptBlock { $PID } | Out-Null if (!$reinit) { if ($bcContainerHelperConfig.debugMode) { Write-Host "Session $cacheName is still valid" } return $session } } catch { if ($bcContainerHelperConfig.debugMode) { Write-Host "Session $cacheName is not valid anymore" } $sessions.Remove($cacheName) $session = $null } } if (!$session) { if ($isInsideContainer) { if ($bcContainerHelperConfig.debugMode) { Write-Host "Creating session from inside container" } $session = New-PSSession -Credential $bcContainerHelperConfig.WinRmCredentials -ComputerName $containerName -Authentication Basic -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) } elseif ($isAdministrator -and !$alwaysUseWinRmSession) { try { if ($bcContainerHelperConfig.debugMode) { Write-Host "Creating $configurationName session using ContainerId" } $containerId = Get-BcContainerId -containerName $containerName $session = New-PSSession -ContainerId $containerId -RunAsAdministrator -ErrorAction SilentlyContinue -ConfigurationName $configurationName } catch { if ($bcContainerHelperConfig.debugMode) { Write-Host "Error creating session using ContainerId.
