Question

我正在尝试部署具有两个DC的Active Directory林。我已经设法在两个VM上部署了DC并安装了ADDS功能。 “ PDC”具有运行和配置目录林的DSC脚本，同样效果很好。我遇到的问题是尝试在第二个DC上运行第二个DSC脚本，此脚本运行ADDS配置以将VM升级为DC并将其加入目录林。我创建了一个嵌套的JSON模板，该模板由主模板调用。但是我遇到了这个错误：

“操作系统类型'Windows'不支持每个处理程序多个VMExtensions。已在输入中添加或指定了带有处理程序'Microsoft.Powershell.DSC'的VMExtension'PrepareBDC'。”

我花了大约一个小时的时间在互联网上闲逛，寻找答案，每个人似乎都在说同样的话...您不能两次安装相同的扩展程序。好的，我明白了为什么这样做有意义，我的问题是我可以配置嵌套模板，以便它不尝试安装扩展，而仅使用VM上已安装的扩展吗？

此错误的含义与所说明的完全相同：您不能拥有同一扩展名的多个副本，您需要做的是将同一扩展名应用于vm，所有输入必须相同。您可以看看this example正是这样做的。这个特定的模板第二次安装扩展程序，以将bdc加入域。

但是，我不喜欢这种方法。我使用Powershell DSC来等待域创建，然后将bdc一次性加入该域。您将使用以下powershell dsc代码段：

xWaitForADDomain DscForestWait {
    DomainName           = $DomainName
    DomainUserCredential = $DomainCreds
    RetryCount           = $RetryCount
    RetryIntervalSec     = $RetryIntervalSec
}

Here's一个完整的例子

Azure ARM模板-运行DSC脚本而不触发扩展安装？
