# AWS::ECS::TaskDefinition ResourceRequirement
<a name="aws-properties-ecs-taskdefinition-resourcerequirement"></a>

The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see [Working with GPUs on Amazon ECS](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-gpu.html) or [Working with Amazon Elastic Inference on Amazon ECS](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-inference.html) in the *Amazon Elastic Container Service Developer Guide*

## Syntax
<a name="aws-properties-ecs-taskdefinition-resourcerequirement-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-ecs-taskdefinition-resourcerequirement-syntax.json"></a>

```
{
  "[Type](#cfn-ecs-taskdefinition-resourcerequirement-type)" : String,
  "[Value](#cfn-ecs-taskdefinition-resourcerequirement-value)" : String
}
```

### YAML
<a name="aws-properties-ecs-taskdefinition-resourcerequirement-syntax.yaml"></a>

```
  [Type](#cfn-ecs-taskdefinition-resourcerequirement-type): String
  [Value](#cfn-ecs-taskdefinition-resourcerequirement-value): String
```

## Properties
<a name="aws-properties-ecs-taskdefinition-resourcerequirement-properties"></a>

`Type`  <a name="cfn-ecs-taskdefinition-resourcerequirement-type"></a>
The type of resource to assign to a container.   
*Required*: Yes  
*Type*: String  
*Allowed values*: `GPU | InferenceAccelerator`  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`Value`  <a name="cfn-ecs-taskdefinition-resourcerequirement-value"></a>
The value for the specified resource type.  
When the type is `GPU`, the value is the number of physical `GPUs` the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.  
When the type is `InferenceAccelerator`, the `value` matches the `deviceName` for an [InferenceAccelerator](https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_InferenceAccelerator.html) specified in a task definition.  
*Required*: Yes  
*Type*: String  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)
