--
-- 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 can\'t use an @INACTIVE@ task definition to run new tasks or create
-- new services, and you can\'t update an existing service to reference an
-- @INACTIVE@ task definition. However, there may be up to a 10-minute
-- window following deregistration where these restrictions have not yet
-- taken effect.
--
-- At this time, @INACTIVE@ task definitions remain discoverable in your
-- account indefinitely. However, this behavior is subject to change in the
-- future. We don\'t recommend that you rely on @INACTIVE@ task definitions
-- persisting beyond the lifecycle of any associated tasks and services.
