Context manager that provides a temporary value of :envvar:`AIRFLOW_CONN_GOOGLE_CLOUD_DEFAULT`
connection. It build a new connection that includes path to provided service json,
required scopes and project id.
Parameters

  • key_file_path (str) – Path to file with Google Cloud Service Account .json file.

  • scopes (Sequence) – OAuth scopes for the connection

  • project_id (str) – The id of Google Cloud project for the connection.

airflow.providers.google.cloud.utils.credentials_provider.provide_gcp_conn_and_credentials(key_file_path: Optional[str] = None, scopes: Optional[Sequence] = None, project_id: Optional[str] = None) → Generator[source]
Context manager that provides both:
Parameters

  • key_file_path (str) – Path to file with Google Cloud Service Account .json file.

  • scopes (Sequence) – OAuth scopes for the connection

  • project_id (str) – The id of Google Cloud project for the connection.
