Putting ELB in from of my ECS Cluster / Service

Question

I’m trying to put an ELB in from of my ECS service, using this terraform file

But applying it, gives the below error. Any ideas on the setup that I’ve gotten wrong?

$ terraform apply ...

Panagiotis Moustafellos in the #devopsengineers slack channel actually helped me fix this issue. Turns out that the beatthemarket_service container does not exist. (Confusingly) It's the beatthemarkettask definition name.

So I just replaced

resource "aws_ecs_service" "beatthemarket_service" {
  name            = "beatthemarket-service"
  cluster         = "${aws_ecs_cluster.default.id}"
  task_definition = "${aws_ecs_task_definition.beatthemarket-task.arn}"
  desired_count   = 1
  iam_role = "${aws_iam_role.beatthemarket_role.arn}"
  load_balancer {
    elb_name = "${aws_elb.beathemarket-elb.name}"
    container_name = "beatthemarket_service"
    container_port = 8080
  }
}

with

resource "aws_ecs_service" "beatthemarket_service" {
  name            = "beatthemarket-service"
  cluster         = "${aws_ecs_cluster.default.id}"
  task_definition = "${aws_ecs_task_definition.beatthemarket-task.arn}"
  desired_count   = 1
  iam_role = "${aws_iam_role.beatthemarket_role.arn}"
  load_balancer {
    elb_name = "${aws_elb.beathemarket-elb.name}"
    container_name = "beatthemarket"
    container_port = 8080
  }
}
