Spot Instance Improvement

We are currently using to bring a host up every hour to run a cron job, once the cron job is done it asks spotinst to shutdown the instance. This has been working great with rancher the only improvement would be to allow to setup a service or stack as a Spot instance service.Currently when the spot instance is not running it continue to mark the service as Unhealthy while recording every minute log entry “failed to satisfy predicate” until the next hour.
