Azure ARM-DSC VM配置

Posted 2021-04-03

我想使用ARM模板和DSC配置我的VM。我使用powershell命令创建的.zip文件在powershell中准备了简单的DCS脚本。提到的.zip文件已上传到存储帐户容器。现在，我想使用此.zip文件在ARM模板下方的测试VM上进行配置更改。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.

答案

根据错误，您无法从所使用的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

Public
