    20    task_definition = "${aws_ecs_task_definition.mongo.family}"
    21  }
    22  
    23  resource "aws_ecs_cluster" "foo" {
    24    name = "foo"
    25  }
    26  
    27  resource "aws_ecs_task_definition" "mongo" {
    28    family = "mongodb"
    29  
    30    container_definitions = <<DEFINITION
    31  [
