# Create a SageMaker HyperPod cluster on training plans using the SageMaker API, or AWS CLI
<a name="use-training-plan-for-hyperpod-creation-using-api-cli-sdk"></a>

To use SageMaker training plans for your Amazon SageMaker HyperPod cluster, specify the ARN of the training plan you want to use in the [https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_ClusterInstanceGroupSpecification.html#sagemaker-Type-ClusterInstanceGroupSpecification-TrainingPlanArn](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_ClusterInstanceGroupSpecification.html#sagemaker-Type-ClusterInstanceGroupSpecification-TrainingPlanArn) parameter of the [https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_ClusterInstanceGroupSpecification.html](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_ClusterInstanceGroupSpecification.html) when calling the [https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_CreateCluster.html](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_CreateCluster.html) API operation. 

Ensure that the subnet associated with the designated AZ of your plan is included in the `VPCConfig` of your cluster configuration. You can retrieve the `AvailabilityZone` of a training plan in the response of a [``DescribeTrainingPlan](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DescribeTrainingPlan.html) API call.

The following sample illustrates how to create a new SageMaker HyperPod cluster and provide an instance group with a training plan in the `--instance-groups` attribute of the `create-cluster` AWS CLI command. 

```
# Create a cluster         
aws sagemaker create-cluster \
  --cluster-name cluster-name \
  --instance-groups '[ \
        { \
            "InstanceCount": 1,\
            "InstanceGroupName": "controller-nodes",\
            "InstanceType": "ml.t3.xlarge",\
            "LifeCycleConfig": {"SourceS3Uri": source_s3_uri, "OnCreate": "on_create.sh"},\
            "ExecutionRole": "arn:aws:iam::customer_account_id:role/execution_role",\
            "ThreadsPerCore": 1,\
        },\
        { \
            "InstanceCount": 2, \
            "InstanceGroupName": "worker-nodes",\
            "InstanceType": "p4d.24xlarge",\
            "LifeCycleConfig": {"SourceS3Uri": source_s3_uri, "OnCreate": "on_create.sh"},\
            "ExecutionRole": "arn:aws:iam::customer_account_id}:role/execution_role}",\
            "ThreadsPerCore": 1,\
            "TrainingPlanArn": training_plan_arn,\
        }]'
```

For information about how to create an HyperPod cluster using the AWS CLI, see [https://docs.aws.amazon.com/cli/latest/reference/sagemaker/create-cluster.html](https://docs.aws.amazon.com/cli/latest/reference/sagemaker/create-cluster.html).

After creating the cluster, you can verify that your instance group was properly assigned capacity from the training plan by calling the `DescribeCluster` API.

```
aws sagemaker describe-cluster --cluster-name cluster-name
```
