Azure Python SDK: 'ServicePrincipalCredentials' object has no attribute 'get_token'

The Azure libraries for Python are currently being updated to share common cloud patterns such as authentication protocols, logging, tracing, transport protocols, buffered responses, and retries.

This would change the Authentication mechanism a bit as well. In the older version, ServicePrincipalCredentials in azure.common was used for authenticating to Azure and creating a service client.

In the newer version, the authentication mechanism has been re-designed and replaced by azure-identity library in order to provide unified authentication based on Azure Identity for all Azure SDKs. Run pip install azure-identity to get the package.

In terms of code, what then was:

from azure.common.credentials import ServicePrincipalCredentialsfrom azure.mgmt.compute import ComputeManagementClientcredentials = ServicePrincipalCredentials(    client_id='xxxxx',    secret='xxxxx',    tenant='xxxxx')compute_client = ComputeManagementClient(    credentials=credentials,    subscription_id=SUBSCRIPTION_ID)

is now:

from azure.identity import ClientSecretCredentialfrom azure.mgmt.compute import ComputeManagementClientcredential = ClientSecretCredential(    tenant_id='xxxxx',    client_id='xxxxx',    client_secret='xxxxx')compute_client = ComputeManagementClient(    credential=credential,    subscription_id=SUBSCRIPTION_ID)

You can then use the list_all method with compute_client to list all VMs as usual:

# List all Virtual Machines in the specified subscriptiondef list_virtual_machines():    for vm in compute_client.virtual_machines.list_all():        print(vm.name)list_virtual_machines()

Incase of Azure sovereign cloud (AZURE_PUBLIC_CLOUD, AZURE_CHINA_CLOUD, AZURE_US_GOV_CLOUD, AZURE_GERMAN_CLOUD), accepted answer would extends to below code snippet.

from azure.identity import ClientSecretCredentialfrom azure.mgmt.compute import ComputeManagementClientfrom msrestazure.azure_cloud import AZURE_US_GOV_CLOUD as cloud_envcredential = ClientSecretCredential(    tenant_id='xxxxx',    client_id='xxxxx',    client_secret='xxxxx',    authority=cloud_env.endpoints.active_directory)compute_client = ComputeManagementClient(    credential=credential,    subscription_id=SUBSCRIPTION_ID    base_url=cloud_env.endpoints.resource_manager,    credential_scopes=[cloud_env.endpoints.resource_manager + ".default"])
