[英]Azure ARM Template - Running DSC script without triggering extension install?
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。输入中已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?
主模板代码段:

嵌套模板:
{

"contentVersion": "1.0.0.0",
"parameters": {

},

"properties": {

"properties": {

"adminCreds": {

}
}
},
"protectedSettings": {
"items": {
"adminPassword": "[parameters('adminPassword')]"
}
}
}
}
]
}
该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。 您可以看一下这个示例 。 此特定模板第二次安装扩展,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
}
这是一个完整的例子
