创建数据存储

项目
08/14/2024

适用范围：Azure CLI ml 扩展 v2（最新版）Python SDK azure-ai-ml v2（最新版）

本文介绍如何通过 Azure 机器学习数据存储连接到 Azure 数据存储服务。

先决条件

Azure 订阅。如果没有 Azure 订阅，可在开始前创建一个试用帐户。尝试试用版订阅。
适用于 Python 的 Azure 机器学习 SDK。
机器学习工作区。

注意

机器学习数据存储不会创建基础存储帐户资源。相反，它们链接现有存储帐户以供机器学习使用。不需要机器学习数据存储。如果有权访问基础数据，可以直接使用存储 URI。

创建 Azure Blob 数据存储

from azure.ai.ml.entities import AzureBlobDatastore
from azure.ai.ml import MLClient

ml_client = MLClient.from_config()

store = AzureBlobDatastore(
    name="",
    description="",
    account_name="",
    container_name=""
)

ml_client.create_or_update(store)

from azure.ai.ml.entities import AzureBlobDatastore
from azure.ai.ml.entities import AccountKeyConfiguration
from azure.ai.ml import MLClient

ml_client = MLClient.from_config()

store = AzureBlobDatastore(
    name="blob_protocol_example",
    description="Datastore pointing to a blob container using https protocol.",
    account_name="mytestblobstore",
    container_name="data-container",
    protocol="https",
    credentials=AccountKeyConfiguration(
        account_key="XXXxxxXXXxXXXXxxXXXXXxXXXXXxXxxXxXXXxXXXxXXxxxXXxxXXXxXxXXXxxXxxXXXXxxxxxXXxxxxxxXXXxXXX"
    ),
)

ml_client.create_or_update(store)

from azure.ai.ml.entities import AzureBlobDatastore
from azure.ai.ml.entities import SasTokenConfiguration
from azure.ai.ml import MLClient

ml_client = MLClient.from_config()

store = AzureBlobDatastore(
    name="blob_sas_example",
    description="Datastore pointing to a blob container using SAS token.",
    account_name="mytestblobstore",
    container_name="data-container",
    credentials=SasTokenConfiguration(
        sas_token= "?xx=XXXX-XX-XX&xx=xxxx&xxx=xxx&xx=xxxxxxxxxxx&xx=XXXX-XX-XXXXX:XX:XXX&xx=XXXX-XX-XXXXX:XX:XXX&xxx=xxxxx&xxx=XXxXXXxxxxxXXXXXXXxXxxxXXXXXxxXXXXXxXXXXxXXXxXXxXX"
    ),
)

ml_client.create_or_update(store)

创建以下 YAML 文件（更新适当的值）：

# my_blob_datastore.yml
$schema: https://azuremlschemas.azureedge.net/latest/azureBlob.schema.json
name: my_blob_ds # add your datastore name here
type: azure_blob
description: here is a description # add a datastore description here
account_name: my_account_name # add the storage account name here
container_name: my_container_name # add the storage container name here
