About supported capacity providers
Section titled “About supported capacity providers”Both capacity provider types FargateProvider and ASGProvider are supported for this task.
Note that the ASGProvider type takes some time to actually scale in after the “number of required tasks” is reduced. Please be careful when using this service.
About supported startup types
Section titled “About supported startup types”This task only supports ECS services with an ECS startup type of Fargate. If the startup type is EC2, use the Auto Scaling Group Resize task.
