Azure Data Lake gen2 (Data Lake Storage) Access Control on container level with Managed Identity

Question

I try to script grant role to Azure Data Lake gen2. The is no issue with adding this for Service Account:

$storageAccount = Get-AzResource -Name $StorageAccountName -ResourceGroupName $ResourceGroupName
$datafactory = Get-AzDataFactoryV2 -Name $DataFactoryName -ResourceGroupName $ResourceGroupName
$contributorRoleDefinition = Get-AzRoleDefinition -Scope $storageAccount.ResourceId -Name 'Contributor'

$dataFactoryRole = Get-AzRoleAssignment -Scope $storageAccount.ResourceId -ObjectId $datafactory.Identity.PrincipalId -RoleDefinitionId $contributorRoleDefinition.Id
if(!$dataFactoryRole)
{
    New-AzRoleAssignment -Scope $storageAccount.ResourceId -ObjectId $datafactory.Identity.PrincipalId -RoleDefinitionId $contributorRoleDefinition.Id
    Write-Host "Access to blob storage for data factory was granted"
}
else
{
    Write-Host "Access to blob storage for data factory has already been granted"
}

The issue is I want to grand permission on container level - not service account level. Above scrip generate on container level: Parent resource (inherited) but what is need is: This resource.

I can do it through portal, but is not valid solution for my case.

Answer 1

If you want to grand permission on container level, please refer to the following script

Connect-AzAccount

$container=Get-AzRmStorageContainer -Name $StorageAccountName -ResourceGroupName $ResourceGroupName -Name $containerName

$datafactory = Get-AzDataFactoryV2 -Name <> -ResourceGroupName <>

$role=Get-AzRoleDefinition -Name "Storage Blob Data Reader"

$dataFactoryRole = Get-AzRoleAssignment -Scope $container.Id -ObjectId $datafactory.Identity.PrincipalId -RoleDefinitionId $role.Id
if(!$dataFactoryRole)
{
    New-AzRoleAssignment -Scope $container.Id -ObjectId $datafactory.Identity.PrincipalId -RoleDefinitionId $role.Id
    Write-Host "Access to blob storage for data factory was granted"
}
else
{
    Write-Host "Access to blob storage for data factory has already been granted"
}

Besides, please note that if you want to access Azure Blob with AD auth, you need to use these roles: Storage Blob Data Contributor, Storage Blob Data Reader and Storage Blob Data Owner. For more details, please refer to here and here
