DSCから呼び出されるCMDの参照資格情報

Question

私はDSCから呼び出されるCMDの資格情報をどのように参照できるのだろうかと思っていました。 これは展開しようとしている構成ですが、資格情報を受信しません。

configuration SQLCMD 
{ 
    param 
    (
     [Parameter(Mandatory=$true)] 
     [ValidateNotNullorEmpty()] 
     [PSCredential] 
     $Credential 

    ) 

    Import-DscResource -ModuleName xSqlServer 

    Node localhost 
    { 

     LocalConfigurationManager 
     { 
      ConfigurationMode = 'ApplyOnly' 
      RebootNodeIfNeeded = $true 
      ActionAfterReboot = 'ContinueConfiguration' 
      AllowModuleOverwrite = $true 
     } 

     Script DeployDBmoveTempDB 
     { 
      SetScript = { 
$SourceFile = 'C:\DatabaseTest.dacpac' 
$TargetServerName = 'localhost' 
$TargetDatabaseName = 'TestDB1' 
$databaseSizeSQLCMD = '200MB' 
$databaseLogSizeSQLCMD = '20MB' 
$tempdbSizeSQLCMD = '1900MB' 
$tempdbLogSizeSQLCMD = '1900MB' 


trap { 
    Write-Error $_ 
    Exit 1 
} 

$args = @('/Action:Publish' 
      ,"/SourceFile:$SourceFile" 
      ,"/TargetServerName:$TargetServerName" 
      ,"/TargetUser:$Credential.UserName" 
      ,"/TargetPassword:$Credential" 
      ,"/TargetDatabaseName:$TargetDatabaseName" 
      ,"/v:databaseSizeSQLCMD=$databaseSizeSQLCMD" 
      ,"/v:databaseLogSizeSQLCMD=$databaseLogSizeSQLCMD" 
      ,"/v:tempdbSizeSQLCMD=$databaseSizeSQLCMD" 
      ,"/v:tempdbLogSizeSQLCMD=$databaseLogSizeSQLCMD" 
      ,'/p:BlockOnPossibleDataLoss=false' 
      )    

    try { 
     & "C:\Program Files (x86)\Microsoft SQL Server\130\DAC\bin\SqlPackage.exe" $args 


    } 
    catch { 
     Write-Host $_ ; 
    } 

     } 

      TestScript = { 
      Test-Path D:\TestDB1_primary.mdf 
     } 
      GetScript = { <# This must return a hash table #> } 
     } 

    } 
} 

ただし、以下の設定が正常に動作します：生成されたMOF内の文字列として

configuration SQLCMD 
{ 
    param 
    (
     [Parameter(Mandatory=$true)] 
     [ValidateNotNullorEmpty()] 
     [PSCredential] 
     $Credential 

    ) 

    Import-DscResource -ModuleName xSqlServer 

    Node localhost 
    { 

     LocalConfigurationManager 
     { 
      ConfigurationMode = 'ApplyOnly' 
      RebootNodeIfNeeded = $true 
      ActionAfterReboot = 'ContinueConfiguration' 
      AllowModuleOverwrite = $true 
     } 

     Script DeployDBmoveTempDB 
     { 
      SetScript = { 
$ErrorActionPreference = "Stop" 
$SourceFile = 'C:\DatabaseTest.dacpac' 
$TargetServerName = 'localhost' 
$user_name = 'mySqlAdmin' 
$user_pwd = 'blabla' 
$TargetDatabaseName = 'TestDB1' 
$databaseSizeSQLCMD = '200MB' 
$databaseLogSizeSQLCMD = '20MB' 
$tempdbSizeSQLCMD = '1900MB' 
$tempdbLogSizeSQLCMD = '1900MB' 


trap { 
    Write-Error $_ 
    Exit 1 
} 

$args = @('/Action:Publish' 
      ,"/SourceFile:$SourceFile" 
      ,"/TargetServerName:$TargetServerName" 
      ,"/TargetUser:$user_name" 
      ,"/TargetPassword:$user_pwd" 
      ,"/TargetDatabaseName:$TargetDatabaseName" 
      ,"/v:databaseSizeSQLCMD=$databaseSizeSQLCMD" 
      ,"/v:databaseLogSizeSQLCMD=$databaseLogSizeSQLCMD" 
      ,"/v:tempdbSizeSQLCMD=$databaseSizeSQLCMD" 
      ,"/v:tempdbLogSizeSQLCMD=$databaseLogSizeSQLCMD" 
      ,'/p:BlockOnPossibleDataLoss=false' 
      )    

    try { 
     & "C:\Program Files (x86)\Microsoft SQL Server\130\DAC\bin\SqlPackage.exe" $args 


    } 
    catch { 
     Write-Host $_ ; 
    } 

     } 

      TestScript = { 
      Test-Path D:\TestDB1_primary.mdf 
     } 
      GetScript = { <# This must return a hash table #> } 
     } 

    } 
}

DSC-構成ストアのスクリプトを、それが拡大しているか分からないであろうから、デフォルトでは、変数を展開しないとこれはスクリプトの一部として保持されます。ただし、$using: -Scopeを指定すると、設定で定義された変数を含めることができます。 mof-compilcation中、変数はGet-Set-TestScriptスクリプトブロックの先頭に追加されます。 例：

configuration SQLCMD 
{ 
    param 
    (
     [Parameter(Mandatory=$true)] 
     [ValidateNotNullorEmpty()] 
     [PSCredential] 
     $Credential  
    ) 

    Import-DscResource -ModuleName xSqlServer 

    $user_name = $Credential.UserName 
    $user_pwd = $Credential.GetNetworkCredential().Password 

    Node localhost 
    {  
     Script DeployDBmoveTempDB 
     { 
      SetScript = { 

       $TargetDatabaseName = 'TestDB1' 
       $args = @(,"/TargetUser:$using:user_name" 
          ,"/TargetPassword:$using:user_pwd" 
          ,"/TargetDatabaseName:$TargetDatabaseName")     
       try { 
        & "C:\Program Files (x86)\Microsoft SQL Server\130\DAC\bin\SqlPackage.exe" $args 
       } 
       catch { Write-Host $_ }  
      }  
      TestScript = { Test-Path "D:\TestDB1_primary.mdf" }    
      GetScript = { <# This must return a hash table #> } 
     } 

    } 
} 

パスワードはMOFファイルにプレーンテキストで保存されることに注意してください。例：

SetScript = "$user_name ='User1'\n$user_pwd ='Password1'\n \n\n    $TargetDatabaseName = 'TestDB1'\n    $args = @(,\"/TargetUser:$user_name\"\n      
     ,\"/TargetPassword:$user_pwd\"\n        ,\"/TargetDatabaseName:$TargetDatabaseName\")   \n\n    try {\n     & \"C:\\Program File 
s (x86)\\Microsoft SQL Server\\130\\DAC\\bin\\SqlPackage.exe\" $args\n    }\n    catch { Write-Host $_ } \n\n   ";
