This module will, in time, replace the current Linode module which uses deprecated API bindings on the Linode side. options: region: description: - The region of the instance.

This label is used as the main determiner for idempotence for the module and is therefore mandatory. type: str required: true group: description: - The group that the instance should be marked under. Please note, that group labelling is deprecated but still supported.
