-After you create a service, the load balancer configuration can't be changed from the AWS Management Console. You can use the AWS Copilot, AWS CloudFormation, AWS CLI or SDK to modify the load balancer configuration for the `ECS` rolling deployment controller only, not AWS CodeDeploy blue/green or external. When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers. We recommend that you verify this on a test environment before you update the ELB configuration. For information about how to modify the configuration, see [UpdateService](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_UpdateService.html) in the _Amazon Elastic Container Service API Reference_.
