如何从 blob 容器中删除超过 30 天的文件？

Question

我正在寻找一种方法来删除存储在名为 reports 的 blob 容器中超过 30 天的文件，或者设置任何其他有意义的保留策略

据我所知，Microsoft 只写了有关日志和元数据的保留策略。 这可能吗？如何实现？

您可以使用 Storage Lifecycle policy 来实现。

#Initialize the following with your resource group and storage account names
$rgname = ""
$accountName = ""

#Create a new action object
$action = Add-AzStorageAccountManagementPolicyAction -BaseBlobAction Delete -daysAfterModificationGreaterThan 2555
$action = Add-AzStorageAccountManagementPolicyAction -InputObject $action -BaseBlobAction TierToArchive -daysAfterModificationGreaterThan 90
$action = Add-AzStorageAccountManagementPolicyAction -InputObject $action -BaseBlobAction TierToCool -daysAfterModificationGreaterThan 30
$action = Add-AzStorageAccountManagementPolicyAction -InputObject $action -SnapshotAction Delete -daysAfterCreationGreaterThan 90

# Create a new filter object
# PowerShell automatically sets BlobType as “blockblob” because it is the only available option currently
$filter = New-AzStorageAccountManagementPolicyFilter -PrefixMatch ab,cd

#Create a new rule object
#PowerShell automatically sets Type as “Lifecycle” because it is the only available option currently
$rule1 = New-AzStorageAccountManagementPolicyRule -Name Test -Action $action -Filter $filter

#Set the policy
$policy = Set-AzStorageAccountManagementPolicy -ResourceGroupName $rgname -StorageAccountName $accountName -Rule $rule1
