# AWS::Batch::JobDefinition EksContainerResourceRequirements
<a name="aws-properties-batch-jobdefinition-ekscontainerresourcerequirements"></a>

The type and amount of resources to assign to a container. The supported resources include `memory`, `cpu`, and `nvidia.com/gpu`. For more information, see [Resource management for pods and containers](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/) in the *Kubernetes documentation*.

## Syntax
<a name="aws-properties-batch-jobdefinition-ekscontainerresourcerequirements-syntax"></a>

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

### JSON
<a name="aws-properties-batch-jobdefinition-ekscontainerresourcerequirements-syntax.json"></a>

```
{
  "[Limits](#cfn-batch-jobdefinition-ekscontainerresourcerequirements-limits)" : {Key: Value, ...},
  "[Requests](#cfn-batch-jobdefinition-ekscontainerresourcerequirements-requests)" : {Key: Value, ...}
}
```

### YAML
<a name="aws-properties-batch-jobdefinition-ekscontainerresourcerequirements-syntax.yaml"></a>

```
  [Limits](#cfn-batch-jobdefinition-ekscontainerresourcerequirements-limits): 
    Key: Value
  [Requests](#cfn-batch-jobdefinition-ekscontainerresourcerequirements-requests): 
    Key: Value
```

## Properties
<a name="aws-properties-batch-jobdefinition-ekscontainerresourcerequirements-properties"></a>

`Limits`  <a name="cfn-batch-jobdefinition-ekscontainerresourcerequirements-limits"></a>
The type and quantity of the resources to reserve for the container. The values vary based on the `name` that's specified. Resources can be requested using either the `limits` or the `requests` objects.    
memory  
The memory hard limit (in MiB) for the container, using whole integers, with a "Mi" suffix. If your container attempts to exceed the memory specified, the container is terminated. You must specify at least 4 MiB of memory for a job. `memory` can be specified in `limits`, `requests`, or both. If `memory` is specified in both places, then the value that's specified in `limits` must be equal to the value that's specified in `requests`.  
To maximize your resource utilization, provide your jobs with as much memory as possible for the specific instance type that you are using. To learn how, see [Memory management](https://docs.aws.amazon.com/batch/latest/userguide/memory-management.html) in the *AWS Batch User Guide*.  
cpu  
The number of CPUs that's reserved for the container. Values must be an even multiple of `0.25`. `cpu` can be specified in `limits`, `requests`, or both. If `cpu` is specified in both places, then the value that's specified in `limits` must be at least as large as the value that's specified in `requests`.  
nvidia.com/gpu  
The number of GPUs that's reserved for the container. Values must be a whole integer. `memory` can be specified in `limits`, `requests`, or both. If `memory` is specified in both places, then the value that's specified in `limits` must be equal to the value that's specified in `requests`.

`Requests`  <a name="cfn-batch-jobdefinition-ekscontainerresourcerequirements-requests"></a>
The type and quantity of the resources to request for the container. The values vary based on the `name` that's specified. Resources can be requested by using either the `limits` or the `requests` objects.    
memory  
The memory hard limit (in MiB) for the container, using whole integers, with a "Mi" suffix. If your container attempts to exceed the memory specified, the container is terminated. You must specify at least 4 MiB of memory for a job. `memory` can be specified in `limits`, `requests`, or both. If `memory` is specified in both, then the value that's specified in `limits` must be equal to the value that's specified in `requests`.  
If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see [Memory management](https://docs.aws.amazon.com/batch/latest/userguide/memory-management.html) in the *AWS Batch User Guide*.  
cpu  
The number of CPUs that are reserved for the container. Values must be an even multiple of `0.25`. `cpu` can be specified in `limits`, `requests`, or both. If `cpu` is specified in both, then the value that's specified in `limits` must be at least as large as the value that's specified in `requests`.  
nvidia.com/gpu  
The number of GPUs that are reserved for the container. Values must be a whole integer. `nvidia.com/gpu` can be specified in `limits`, `requests`, or both. If `nvidia.com/gpu` is specified in both, then the value that's specified in `limits` must be equal to the value that's specified in `requests`.
