The Microsoft Azure Msi Management Client Library for Python provides functionality to manage Managed Service Identities (MSI) within Azure. These identities facilitate secure, credential-less authentication for Azure resources. It is part of the actively developed Azure SDK for Python, with a consistent release cadence for both stable and preview versions. The current stable version is 7.1.0.
pip install azure-mgmt-msiVerified import paths — ran on the pinned version, not inferred.
Initializes the `ManagedServiceIdentityClient` using `DefaultAzureCredential` for authentication, requiring environment variables for Azure AD credentials and subscription ID. It then demonstrates listing user-assigned identities in the specified subscription.
Migrate your authentication code to use classes from the `azure-identity` package, such as `DefaultAzureCredential`. Update client instantiation to use the `credential` parameter.
Consult the official Azure SDK for Python migration guides, specifically for hybrid models (https://aka.ms/azsdk/python/migrate/hybrid-models) and operation changes (https://aka.ms/azsdk/python/migrate/operations).
Ensure your development and deployment environments use Python 3.9 or a newer compatible version.
Pass the `api_version` parameter with a specific date string (e.g., `api_version='2023-01-31'`) to the `ManagedServiceIdentityClient` constructor.
Set the AZURE_SUBSCRIPTION_ID environment variable to a valid Azure subscription ID before running the script (e.g., export AZURE_SUBSCRIPTION_ID='your-subscription-id').
Ensure necessary environment variables, such as `AZURE_SUBSCRIPTION_ID`, are set before initializing Azure SDK clients or executing operations. Refer to the Azure SDK for Python documentation on authentication for details.
If running on an Azure resource (e.g., VM, App Service, Function App), ensure a system-assigned or user-assigned managed identity is enabled for that resource and has the necessary Role-Based Access Control (RBAC) permissions to access the target Azure resources. Verify network settings if within a Virtual Network. If running locally, use an alternative credential type for local development, such as `DefaultAzureCredential` (which will fall back to environment variables or Azure CLI login), `ClientSecretCredential`, `InteractiveBrowserCredential`, or `AzureCliCredential`.
Install the `azure-mgmt-msi` package using pip. It is also recommended to install `azure-identity` for modern Azure SDK authentication. If using virtual environments, ensure the correct environment is activated before installation and execution. ```bash pip install azure-mgmt-msi azure-identity ```
The recommended solution is to update all Azure SDK packages, especially the specific management client causing the error, to their latest versions. Newer clients are designed to directly accept `azure-identity` credential objects. If updating is not immediately possible and you must use an older client, you can use `AzureIdentityCredentialWrapper` from `azure.mgmt.core.tools` to adapt the `ManagedIdentityCredential` for compatibility.
```python
from azure.identity import ManagedIdentityCredential
from azure.mgmt.core.tools import AzureIdentityCredentialWrapper
from azure.mgmt.msi import ManagedServiceIdentityClient # Example of a compatible client
import os
credential = ManagedIdentityCredential()
# If an older client requires 'signed_session', wrap the credential:
# wrapped_credential = AzureIdentityCredentialWrapper(credential)
subscription_id = os.getenv("AZURE_SUBSCRIPTION_ID")
if not subscription_id:
raise ValueError("AZURE_SUBSCRIPTION_ID environment variable not set.")
# Use the credential directly if the client is modern and compatible
client = ManagedServiceIdentityClient(credential=credential, subscription_id=subscription_id)
# Or use the wrapped_credential if the specific client requires it for older versions
# client = SomeOldManagementClient(wrapped_credential, subscription_id)
```Generate a new client secret for your Azure AD Application (Service Principal) in the Azure portal under 'App registrations' -> 'Certificates & secrets'. Update your application's configuration with the new client secret. Consider using certificate credentials for enhanced security and longer validity.
