Retrieves Connections and Variables from Hashicorp Vault.
Configurable via
airflow.cfg
as follows:[secrets] backend = airflow.providers.hashicorp.secrets.vault.VaultBackend backend_kwargs = { "connections_path": "connections", "url": "http://127.0.0.1:8200", "mount_point": "airflow" }
For example, if your keys are under
connections
path inairflow
mount_point, this would be accessible if you provide{"connections_path": "connections"}
and request conn_idsmtp_default
.- Parameters:
connections_path (str) – Specifies the path of the secret to read to get Connections. (default: ‘connections’). If set to None (null), requests for connections will not be sent to Vault.
variables_path (str) – Specifies the path of the secret to read to get Variable. (default: ‘variables’). If set to None (null), requests for variables will not be sent to Vault.
config_path (str) – Specifies the path of the secret to read Airflow Configurations (default: ‘config’). If set to None (null), requests for configurations will not be sent to Vault.
url (str | None) – Base URL for the Vault instance being addressed.
auth_type (str) – Authentication Type for Vault. Default is
token
. Available values are: (‘approle’, ‘aws_iam’, ‘azure’, ‘github’, ‘gcp’, ‘kubernetes’, ‘ldap’, ‘radius’, ‘token’, ‘userpass’)auth_mount_point (str | None) – It can be used to define mount_point for authentication chosen Default depends on the authentication method used.
mount_point (str | None) – The “path” the secret engine was mounted on. Default is “secret”. Note that this mount_point is not used for authentication if authentication is done via a different engine. If set to None, the mount secret should be provided as a prefix for each variable/connection_id. For authentication mount_points see, auth_mount_point.
kv_engine_version (int) – Select the version of the engine to run (
