An enumeration.

gretel_client.config.clear_gretel_config()

Removes any Gretel configuration files from the host file system.

If any Gretel related environment variables exist, this will also remove them from the current processes.

gretel_client.config.configure_session(config: Union[str, gretel_client.config.ClientConfig, None] = None, *, api_key: Optional[str] = None, endpoint: Optional[str] = None, cache: str = 'no', validate: bool = False, clear: bool = False)

Updates client config for the session

Parameters

  • config – The config to update. This config takes precedence over other parameters such as api_key or endpoint.

  • api_key – Configures your Gretel API key. If api_key is set to “prompt” and no Api Key is found on the system, getpass will be used to prompt for the key.

  • endpoint – Specifies the Gretel API endpoint. This must be a fully qualified URL.

  • cache – Valid options include “yes” and “no”. If cache is “no” the session configuration will not be written to disk. If cache is “yes”, session configuration will be written to disk only if a configuration doesn’t exist.

  • validate – If set to True this will check that login credentials are valid.

  • clear – If set to True any existing Gretel credentials will be removed from the host.

Raises

GretelClientConfigurationError if validate=True and credentials – are invalid.

gretel_client.config.get_session_config() → gretel_client.config.ClientConfig
