Retrieves Connection object from Google Cloud Secrets Manager

Configurable via airflow.cfg as follows:

[secrets]
backend = airflow.providers.google.cloud.secrets.secret_manager.CloudSecretManagerBackend
backend_kwargs = {"connections_prefix": "airflow-connections", "sep": "-"}

For example, if the Secrets Manager secret id is airflow-connections-smtp_default, this would be accessible if you provide {"connections_prefix": "airflow-connections", "sep": "-"} and request conn_id smtp_default.

If the Secrets Manager secret id is airflow-variables-hello, this would be accessible if you provide {"variables_prefix": "airflow-variables", "sep": "-"} and request Variable Key hello.

The full secret id should follow the pattern "[a-zA-Z0-9-_]".

Parameters

  • connections_prefix (str) -- Specifies the prefix of the secret to read to get Connections. If set to None (null), requests for connections will not be sent to GCP Secrets Manager

  • variables_prefix (str) -- Specifies the prefix of the secret to read to get Variables. If set to None (null), requests for variables will not be sent to GCP Secrets Manager

  • config_prefix (str) -- Specifies the prefix of the secret to read to get Airflow Configurations containing secrets. If set to None (null), requests for configurations will not be sent to GCP Secrets Manager

  • gcp_key_path (str) -- Path to Google Cloud Service Account key file (JSON). Mutually exclusive with gcp_keyfile_dict. use default credentials in the current environment if not provided.

  • gcp_keyfile_dict (dict) -- Dictionary of keyfile parameters. Mutually exclusive with gcp_key_path.

  • gcp_scopes (str) -- Comma-separated string containing OAuth2 scopes

  • project_id (str) -- Project ID to read the secrets from. If not passed, the project ID from credentials will be used.

  • sep (str) -- Separator used to concatenate connections_prefix and conn_id. Default: "-"
