Azure: create storage account with container and upload blob to it in Python

Question

I'm trying to create a storage account in Azure and upload a blob into it using their python SDK. I managed to create an account like this:

client = get_client_from_auth_file(StorageManagementClient)
storage_account = client.storage_accounts.create(
        resourceGroup,
        name,
        StorageAccountCreateParameters(
            sku=Sku(name=SkuName.standard_ragrs),
            enable_https_traffic_only=True,
            kind=Kind.storage,
            location=region)).result()

The problem is that later I'm trying to build a container and I don't know what to insert as "account_url" I have tried doing:

client = get_client_from_auth_file(BlobServiceClient, account_url=storage_account.primary_endpoints.blob)
return client.create_container(name)

But I'm getting:

azure.core.exceptions.ResourceNotFoundError: The specified resource does not exist

I did manage to create a container using:

client = get_client_from_auth_file(StorageManagementClient)
return client.blob_containers.create(
    resourceGroup,
    storage_account.name,
    name,
    BlobContainer(),
    public_access=PublicAccess.Container
)

But later when I'm trying to upload a blob using BlobServiceClient or BlobClien I still need the "account_url" so I'm still getting an error:

azure.core.exceptions.ResourceNotFoundError: The specified resource does not exist

Anyone can help me to understand how do I get the account_url for a storage account I created with the SDK?

EDIT: I managed to find a workaround to the problem by creating the connection string from the storage keys.

storage_client = get_client_from_auth_file(StorageManagementClient)
storage_keys = storage_client.storage_accounts.list_keys(resource_group, account_name)
    storage_key = next(v.value for v in storage_keys.keys)
    return BlobServiceClient.from_connection_string(
        'DefaultEndpointsProtocol=https;' +
        f'AccountName={account_name};' +
        f'AccountKey={storage_key};' +
        'EndpointSuffix=core.windows.net')

This works but I thin George Chen answer is more elegant.

Can you print client you got from this line client = get_client_from_auth_file(BlobServiceClient, account_url=storage_account.primary_endpoints.blob)? — Gaurav Mantri
Yes, I get <azure.storage.blob._blob_service_client.BlobServiceClient object at 0x103218be0> btw if I print client.account_name it is the right name — Sean Goldfarb

I could reproduce this problem, then I found get_client_from_auth_file could not pass the credential to the BlobServiceClient, cause if just create BlobServiceClient with account_url without credential it also could print the account name.

So if you want to use a credential to get BlobServiceClient, you could use the below code, then do other operations.

credentials = ClientSecretCredential(
    'tenant_id',
    'application_id',
    'application_secret'
)

blobserviceclient=BlobServiceClient(account_url=storage_account.primary_endpoints.blob,credential=credentials)

If you don't want this way, you could create the BlobServiceClient with the account key.

client = get_client_from_auth_file(StorageManagementClient,auth_path='auth')

storage_account = client.storage_accounts.create(
        'group name',
        'account name',
        StorageAccountCreateParameters(
            sku=Sku(name=SkuName.standard_ragrs),
            enable_https_traffic_only=True,
            kind=Kind.storage,
            location='eastus',)).result()
storage_keys = client.storage_accounts.list_keys(resource_group_name='group name',account_name='account name')
storage_keys = {v.key_name: v.value for v in storage_keys.keys}
blobserviceclient=BlobServiceClient(account_url=storage_account.primary_endpoints.blob,credential=storage_keys['key1'])
blobserviceclient.create_container(name='container name')
