+### Deployment circuit breaker and rollback
+
+Amazon ECS [deployment circuit breaker](https://aws.amazon.com/tw/blogs/containers/announcing-amazon-ecs-deployment-circuit-breaker/)
+automatically rolls back unhealthy service deployments without the need for manual intervention. Use `circuitBreaker` to enable
+deployment circuit breaker and optionally enable `rollback` for automatic rollback. See [Using the deployment circuit breaker](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/deployment-type-ecs.html)
+for more details.
