     9  # aws\_ecs\_task\_definition
    10  
    11  Provides an ECS task definition to be used in `aws_ecs_service`.
    12  
    13  ## Example Usage
    14  
    15  ```
    16  resource "aws_ecs_task_definition" "service" {
    17    family                = "service"
    18    container_definitions = "${file("task-definitions/service.json")}"
    19  
    20    volume {
    21      name      = "service-storage"
    22      host_path = "/ecs/service-storage"
    23    }
    24  
    25    placement_constraints {
    26      type       = "memberOf"
    27      expression = "attribute:ecs.availability-zone in [us-west-2a, us-west-2b]"
    28    }
    29  }
    30  ```
    31  
    32  The referenced `task-definitions/service.json` file contains a valid JSON document,
    33  which is show below, and its content is going to be passed directly into the
    34  `container_definitions` attribute as a string. Please note that this example
    35  contains only a small subset of the available parameters.
    36  
    37  ```
    38  [
    39    {
    40      "name": "first",
    41      "image": "service-first",
    42      "cpu": 10,
    43      "memory": 512,
    44      "essential": true,
    45      "portMappings": [
    46        {

    49        }
    50      ]
    51    },

    68  ## Argument Reference
    69  
    70  The following arguments are supported:
    71  
    72  * `family` - (Required) An unique name for your task definition.
    73  * `container_definitions` - (Required) A list of valid [container definitions]
    74  (http://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_ContainerDefinition.html) provided as a
    75  single valid JSON document. Please note that you should only provide values that are part of the container
    76  definition document. For a detailed description of what parameters are available, see the [Task Definition Parameters]
    77  (https://docs.aws.amazon.com/AmazonECS/latest/developerguide/task_definition_parameters.html) section from the
    78  official [Developer Guide](https://docs.aws.amazon.com/AmazonECS/latest/developerguide).
    79  * `task_role_arn` - (Optional) The ARN of IAM role that allows your Amazon ECS container task to make calls to other AWS services.
    80  * `network_mode` - (Optional) The Docker networking mode to use for the containers in the task. The valid values are `none`, `bridge`, and `host`.
    81  * `volume` - (Optional) A volume block. See below for details about what arguments are supported.
    82  * `placement_constraints` - (Optional) rules that are taken into consideration during task placement. Maximum number of
    83  `placement_constraints` is `10`. Defined below.
    84  
    85  Volume block supports the following arguments:
    86  
    87  * `name` - (Required) The name of the volume. This name is referenced in the `sourceVolume`
    88  parameter of container definition in the `mountPoints` section.
    89  * `host_path` - (Optional) The path on the host container instance that is presented to the container. If not set, ECS will create a nonpersistent data volume that starts empty and is deleted after the task has finished.
    90  
    91  ## placement_constraints
    92  
    93  `placement_constraints` support the following:
    94  
    95  * `type` - (Required) The type of constraint. Use `memberOf` to restrict selection to a group of valid candidates.
    96  Note that `distinctInstance` is not supported in task definitions.
    97  * `expression` -  (Optional) Cluster Query Language expression to apply to the constraint.
    98  For more information, see [Cluster Query Language in the Amazon EC2 Container
