Verified ECS Managed Daemons on Managed Instances. Daemons start 18-21 seconds before app tasks, and rolling deployments complete in ~5 minutes with zero downtime.
Hands-on verification of Amazon ECS Linear and Canary deployments with NLB. Measured how the NLB-specific 10-minute delay accumulates per step, making step count the deployment time bottleneck.
If ECS Managed Daemons won't start, check that the instance profile uses AmazonECSInstanceRolePolicyForManagedInstances. The legacy AmazonEC2ContainerServiceforEC2Role won't work.
AmazonECSInfrastructureRolePolicyForLoadBalancers ARN doesn't use the service-role/ prefix. Using the same pattern as other ECS policies causes AttachRolePolicy to fail.
No need to recreate the ECS service — update-service with --deployment-configuration switches between Linear and Canary strategies in place.
