    11  -> **Note:** To prevent race condition during service deletion, make sure to set `depends_on` to related `aws_iam_role_policy`, otherwise policy may be destroyed too soon and ECS service will then stuck in `DRAINING` state.
    12  
    13  Provides an ECS service - effectively a task that is expected to run until an error occures or user terminates it (typically a webserver or a database).
    14  
    15  See [ECS Services section in AWS developer guide](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs_services.html).
    16  
    17  ## Example Usage
    18  
    19  ```
    20  resource "aws_ecs_service" "mongo" {
    21    name = "mongodb"
    22    cluster = "${aws_ecs_cluster.foo.id}"
    23    task_definition = "${aws_ecs_task_definition.mongo.arn}"
    24    desired_count = 3
    25    iam_role = "${aws_iam_role.foo.arn}"
    26    depends_on = ["aws_iam_role_policy.foo"]
    27  
    28    load_balancer {
    29      elb_name = "${aws_elb.foo.name}"
    30      container_name = "mongo"
    31      container_port = 8080
    32    }
    33  }
    34  ```
    35  
    36  ## Argument Reference
    37  
    38  The following arguments are supported:
    39  
    40  * `name` - (Required) The name of the service (up to 255 letters, numbers, hyphens, and underscores)
    41  * `task_definition` - (Required) The family and revision (`family:revision`) or full ARN of the task definition that you want to run in your service.
    42  * `desired_count` - (Required) The number of instances of the task definition to place and keep running
    43  * `cluster` - (Optional) ARN of an ECS cluster
    44  * `iam_role` - (Optional) IAM role that allows your Amazon ECS container agent to make calls to your load balancer on your behalf. This parameter is only required if you are using a load balancer with your service.
    45  * `deployment_maximum_percent` - (Optional) The upper limit (as a percentage of the service's desiredCount) of the number of running tasks that can be running in a service during a deployment.
    46  * `deployment_minimum_healthy_percent` - (Optional) The lower limit (as a percentage of the service's desiredCount) of the number of running tasks that must remain running and healthy in a service during a deployment.
    47  * `load_balancer` - (Optional) A load balancer block. Load balancers documented below.
    48  
    49  -> **Note:** As a result of AWS limitation a single `load_balancer` can be attached to the ECS service at most. See [related docs](http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-load-balancing.html#load-balancing-concepts).
    50  
    51  Load balancers support the following:
    52  
    53  * `elb_name` - (Required) The name of the load balancer.
    54  * `container_name` - (Required) The name of the container to associate with the load balancer (as it appears in a container definition).
    55  * `container_port` - (Required) The port on the container to associate with the load balancer.
    56
