rolloutState

The rolloutState of a service is only returned for services that use the rolling update (ECS) deployment type that aren't behind a Classic Load Balancer.

The rollout state of the deployment. When a service deployment is started, it begins in an IN_PROGRESS state. When the service reaches a steady state, the deployment transitions to a COMPLETED state. If the service fails to reach a steady state and circuit breaker is turned on, the deployment transitions to a FAILED state. A deployment in FAILED state doesn't launch any new tasks. For more information, see DeploymentCircuitBreaker.
