Powershell YAML中CloudFormation模板中的联接函数未按预期工作

作为我在AWS中使用的CloudFormation模板的一部分，我正在创建一个本地PS1文件以将服务器加入到域中

'c:\cfn\joindomain.ps1':
  content: !Join
    - ''
    - - $ServerNamePS = "
      - !Ref ServerName
      - |
        "
      - $UserPS = "
      - !Ref Domain
      - \
      - !Ref DomainUser
      - |
        "
      - $PassPS = ConvertTo-SecureString "
      - !Ref DomainPass
      - |
        " -AsPlainText -Force
      - |
      - $DomainCred = New-Object System.Management.Automation.PSCredential $UserPS, $PassPS
      - |
      - $DomainPS = "
      - !Ref Domain
      - |
        "
      - $DomainOU = "
      - !FindInMap 
        - OUTempComputer
        - !Ref 'AWS::Region'
        - !Ref NetbiosDomain
      - |
        "
      - |
        echo "Joining server $ServerNamePS to domain $DomainPS with user $UserPS"
      - |
        if (!(Get-ADComputer $ServerNamePS -Server (Get-ADDomainController -Discover -Service "GlobalCatalog" -DomainName $DomainPS).HostName[0] -Credential $DomainCred)) {Add-Computer -DomainName $DomainPS -Credential $DomainCred -ouPath $DomainOU -Restart -Force}

因此，在已创建的服务器上，我获得以下PowerShell文件c:\cfn\joindomain.ps1:

$ServerNamePS = "TST-SRV"
$UserPS = "locdom.com\ad.joiner"
$PassPS = ConvertTo-SecureString "123456" -AsPlainText -Force
$DomainCred = New-Object System.Management.Automation.PSCredential $UserPS, $PassPS$DomainPS = "locdom.com"
$DomainOU = "OU=AWS,DC=locdom,DC=com"
echo "Joining server $ServerNamePS to domain $DomainPS with user $UserPS"
if (!(Get-ADComputer $ServerNamePS -Server (Get-ADDomainController -Discover -Service "GlobalCatalog" -DomainName $DomainPS).HostName[0] -Credential $DomainCred)) {Add-Computer -DomainName $DomainPS -Credential $DomainCred -ouPath $DomainOU -Restart -Force}

如果您查看生成的PS1文件中的第4行，您会发现在PassPS和DomainPS变量之间没有新行（

“$PassPS$DomainPS”

）

如何确保这两个变量之间在给定的YAML语法中有新行？显然，我没有正确使用“|”

多谢各位

感谢@lexicore的建议，这是一个更新的工作解决方案：

    'c:\cfn\joindomain.ps1':
      content: !Sub
        - |
          $ServerNamePS = "${ServerName}"
          $UserPS = "${Domain}\${DomainUser}"
          $PassPS = ConvertTo-SecureString "${DomainPass}" -AsPlainText -Force
          $DomainCred = New-Object System.Management.Automation.PSCredential $UserPS, $PassPS
          $DomainPS = "${Domain}"
          $DomainOU = "${DomainOU}"
          echo "Joining server $ServerNamePS to domain $DomainPS with user $UserPS"
          $DomainGC = (Get-ADDomainController -Discover -Service "GlobalCatalog" -DomainName $DomainPS).HostName[0]
          try {Get-ADComputer $ServerNamePS -Server $DomainGC -Credential $DomainCred -ErrorAction Stop}
          catch {Add-Computer -DomainName $DomainPS -Credential $DomainCred -ouPath $DomainOU -Restart -Force}
        - {
          DomainOU: !FindInMap [OUTempComputer, !Ref "AWS::Region", !Ref NetbiosDomain]
          }

不完全是对你问题的回答，但我建议替换

！用
加入
！Sub


大致如下：

content: !Sub
  - |-
    $ServerNamePS = "${ServerName}"
    $UserPS = "${Domain}\${DomainUser}"
    ...

我们找到了
！Sub
更容易处理该
！加入
它可以工作！我将添加工作语法作为答案。谢谢你@lexicore
