使用 PowerShell 创建用于复制云端数据的数据工厂管道

本 PowerShell 脚本示例在 Azure 数据工厂中创建管道，该管道将数据从 Azure Blob 存储中的一个位置复制到另一个位置。

本示例需要 Azure PowerShell。 运行 Get-Module -ListAvailable Az 即可查找版本。 如果需要进行安装或升级，请参阅安装 Azure PowerShell 模块。

运行 Connect-AzAccount -Environment AzureChinaCloud cmdlet 以连接到世纪互联运营的 Azure。

• Azure 存储帐户。 可以将 blob 存储同时用作源和接收器数据存储。 如果没有 Azure 存储帐户，请参阅创建存储帐户创建一个。
• 在 Blob 存储中创建一个 blob 容器，在该容器中创建一个输入文件夹，并向该文件夹上传一些文件。 可以使用 Azure 存储资源管理器等工具连接到 Azure Blob 存储、创建 Blob 容器、上传输入文件，以及验证输出文件。

$sinkBlobPath = "<Azure blob container name>/<Azure blob output folder name>" # example: adftutorial/output

# To remove the data factory from the resource gorup
# Remove-AzDataFactoryV2 -Name $dataFactoryName -ResourceGroupName $resourceGroupName
# 
# To remove the whole resource group
# Remove-AzResourceGroup  -Name $resourceGroupName

运行示例脚本后，可以使用以下命令删除资源组以及与其关联的所有资源：

Remove-AzResourceGroup -ResourceGroupName $resourceGroupName

若要从资源组中删除数据工厂，请运行以下命令：

Remove-AzDataFactoryV2 -Name $dataFactoryName -ResourceGroupName $resourceGroupName

此脚本使用以下命令：
