Microsoft Azure File Share Connection

The Microsoft Azure File Share connection type enables the Azure File Share Integrations.

Authenticating to Azure File Share

There are five ways to connect to Azure File Share using Airflow.

  1. Use token credentials i.e. add specific credentials (client_id, secret) and subscription id to the Airflow connection.

  2. Use a SAS Token i.e. add a key config to sas_token in the Airflow connection.

  3. Use a Connection String i.e. add connection string to connection_string in the Airflow connection.

  4. Use managed identity by setting managed_identity_client_id, workload_identity_tenant_id (under the hook, it uses DefaultAzureCredential with these arguments)

  5. Fallback on DefaultAzureCredential. This includes a mechanism to try different options to authenticate: Managed System Identity, environment variables, authentication through Azure CLI and etc.

Only one authorization method can be used at a time. If you need to manage multiple credentials or keys then you should configure multiple connections.

Default Connection IDs

All hooks and operators related to Azure File Share use azure_fileshare_default by default.

Configuring the Connection

Login (optional)

Specify the login used for azure blob storage. For use with Shared Key Credential, SAS Token authentication and DefaultAzureCredential.

Password (optional)

Specify the password used for azure blob storage. For use with Active Directory (token credential) and shared key authentication. It can be left out to fall back on DefaultAzureCredential.

Host (optional)

Specify the account url for anonymous public read, Active Directory, shared access key authentication.

Extra (optional)

Specify the extra parameters (as json dictionary) that can be used in Azure connection. The following parameters are all optional:

  • connection_string: Connection string for use with connection string authentication. It can be left out to fall back on DefaultAzureCredential.

  • sas_token: SAS Token for use with SAS Token authentication. It can be left out to fall back on DefaultAzureCredential.

  • managed_identity_client_id: The client ID of a user-assigned managed identity. If provided with workload_identity_tenant_id, they’ll pass to DefaultAzureCredential.

  • workload_identity_tenant_id: ID of the application’s Microsoft Entra tenant. Also called its “directory” ID. If provided with managed_identity_client_id, they’ll pass to DefaultAzureCredential.

When specifying the connection in environment variable you should specify it using URI syntax.

Note that all components of the URI should be URL-encoded.

For example connect with token credentials:

export AIRFLOW_CONN_WASP_DEFAULT='azure_fileshare://'
