### 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.

```ts
const service = new ApplicationLoadBalancedFargateService(stack, 'Service', {
cluster,
memoryLimitMiB: 1024,
desiredCount: 1,
cpu: 512,
taskImageOptions: {
image: ecs.ContainerImage.fromRegistry("amazon/amazon-ecs-sample"),
},
deploymentController: {
type: ecs.DeploymentControllerType.ECS,
},
circuitBreaker: { rollback: true },
});
```

### Use the REMOVE_DEFAULT_DESIRED_COUNT feature flag

The REMOVE_DEFAULT_DESIRED_COUNT feature flag is used to override the default desiredCount that is autogenerated by the CDK. This will set the desiredCount of any service created by any of the following constructs to be undefined.
