Bases: airflow.secrets.BaseSecretsBackend, airflow.utils.log.logging_mixin.LoggingMixin

Retrieves Connection object from GCP Secrets Manager

Configurable via airflow.cfg as follows:

backend = airflow.contrib.secrets.gcp_secrets_manager.CloudSecretsManagerBackend
backend_kwargs = {"connections_prefix": "airflow-connections", "sep": "-"}

For example, if the Secrets Manager secret id is airflow-connections-smtp_default, this would be accessiblen 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-_]”.

  • connections_prefix (str) – Specifies the prefix of the secret to read to get Connections.

  • variables_prefix (str) – Specifies the prefix of the secret to read to get Variables.

  • gcp_key_path (str) – Path to GCP Credential JSON file; use default credentials in the current environment if not provided.

  • gcp_scopes (str) – Comma-separated string containing GCP scopes

  • sep (str) – separator used to concatenate connections_prefix and conn_id. Default: “-“
