Description

There are several new AWS features for ECS which depend on settings being enabled. I have a workaround for the default running local-exec but it'd be nice if there was a way to do this with the usual Terraform niceties such as change detection:

resource "null_resource" "enable_new_ecs_features" {
  provisioner "local-exec" {
    command = <<EOF
aws ecs put-account-setting-default --name awsvpcTrunking --value enabled
aws ecs put-account-setting-default --name containerInstanceLongArnFormat --value enabled
aws ecs put-account-setting-default --name serviceLongArnFormat --value enabled
aws ecs put-account-setting-default --name taskLongArnFormat --value enabled
EOF
  }
}

New or Affected Resource(s)

• PutAccountSettingDefault

Potential Terraform Configuration

It'd be nice if something like this could work:

resource "aws_ecs_account_setting_default" "vpc_trunking" {
   name = "awsvpcTrunking" 
   value = "enabled"
}
