# AWS::SageMaker::Space ResourceSpec
<a name="aws-properties-sagemaker-space-resourcespec"></a>

Specifies the ARN's of a SageMaker AI image and SageMaker AI image version, and the instance type that the version runs on.

**Note**  
When both `SageMakerImageVersionArn` and `SageMakerImageArn` are passed, `SageMakerImageVersionArn` is used. Any updates to `SageMakerImageArn` will not take effect if `SageMakerImageVersionArn` already exists in the `ResourceSpec` because `SageMakerImageVersionArn` always takes precedence. To clear the value set for `SageMakerImageVersionArn`, pass `None` as the value.

## Syntax
<a name="aws-properties-sagemaker-space-resourcespec-syntax"></a>

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

### JSON
<a name="aws-properties-sagemaker-space-resourcespec-syntax.json"></a>

```
{
  "[InstanceType](#cfn-sagemaker-space-resourcespec-instancetype)" : String,
  "[LifecycleConfigArn](#cfn-sagemaker-space-resourcespec-lifecycleconfigarn)" : String,
  "[SageMakerImageArn](#cfn-sagemaker-space-resourcespec-sagemakerimagearn)" : String,
  "[SageMakerImageVersionArn](#cfn-sagemaker-space-resourcespec-sagemakerimageversionarn)" : String
}
```

### YAML
<a name="aws-properties-sagemaker-space-resourcespec-syntax.yaml"></a>

```
  [InstanceType](#cfn-sagemaker-space-resourcespec-instancetype): String
  [LifecycleConfigArn](#cfn-sagemaker-space-resourcespec-lifecycleconfigarn): String
  [SageMakerImageArn](#cfn-sagemaker-space-resourcespec-sagemakerimagearn): String
  [SageMakerImageVersionArn](#cfn-sagemaker-space-resourcespec-sagemakerimageversionarn): String
```

## Properties
<a name="aws-properties-sagemaker-space-resourcespec-properties"></a>

`InstanceType`  <a name="cfn-sagemaker-space-resourcespec-instancetype"></a>
The instance type that the image version runs on.  
**JupyterServer apps** only support the `system` value.  
For **KernelGateway apps**, the `system` value is translated to `ml.t3.medium`. KernelGateway apps also support all other values for available instance types.
