v0.42.0

on GitHub

what

• In the case of registering more than one Target Group, don't create or pass the ECS service IAM role to the aws_ecs_service block.

why

• If you are registering multiple target groups to the service, you must allow ECS to create a service-linked role rather than passing one that was manually created. Passing one results in an API error from ECS: Error: InvalidParameterException: You cannot specify an IAM role for services that require a service linked role.
