Azure ARM - DSC 虚拟机配置

Question

我想使用 ARM 模板和 DSC 配置我的 VM。我在 powershell 中准备了简单的 DCS 脚本，基于使用 powershell 命令创建的 .zip 文件。提到的 .zip 文件上传到存储帐户容器。现在我想使用这个 .zip 文件在我的 ARM 模板下面对我的测试虚拟机进行配置更改。我收到错误消息 New-AzResourceGroupDeployment : 10:12:09 AM - VM has reported a failure when processing extension 'dscExtension'. Error message: "The DSC Extension failed to execute: Error downloading https://storageAccountName.blob.core.windows.net/containerName/test.zip after 2 attempts: <?xml version="1.0" encoding="utf-8"?><Error><Code>ResourceNotFound</Code><Message>The specified resource does not exist.

DSC部分：

Configuration SetRegistryxxx {


    Node 'localhost' {

                Ensure = "Present"
                Key = "HKLM:\xx"
                ValueName = "xx"

        Registry configxxx {

根据错误，您无法从您使用的 Azure blob 存储帐户下载 zip 文件。请为 blob 或 set the blob access level to Public.

创建一个 sas 令牌

例如

 "resources": [
    {
      "type": "Microsoft.Compute/virtualMachines/extensions",
      "name": "[concat(parameters('vmName'),'/Microsoft.Powershell.DSC')]",
      "apiVersion": "2015-06-15",
      "location": "[parameters('location')]",
      "properties": {
        "publisher": "Microsoft.Powershell",
        "type": "DSC",
        "typeHandlerVersion": "2.19",
        "autoUpgradeMinorVersion": true,
        "protectedSettings": {
          "Items": {
            "registrationKeyPrivate": "[parameters('registrationKey')]"
          }
        },
        "settings": {
          "ModulesUrl": "<the url of you azure blob>",
          "SasToken": "<the sas token for the blob>",
          "ConfigurationFunction": "[parameters('configurationFunction')]",
        ...
}
]
