-- Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as @INACTIVE@ . Existing tasks and services that reference an @INACTIVE@ task definition continue to run without disruption. Existing services that reference an @INACTIVE@ task definition can still scale up or down by modifying the service's desired count.
--
--
-- You cannot use an @INACTIVE@ task definition to run new tasks or create new services, and you cannot update an existing service to reference an @INACTIVE@ task definition (although there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect).
