# 使用 SageMaker API 更新 SageMaker HyperPod 集群的训练计划，或者 AWS CLI
<a name="use-training-plan-for-hyperpod-update-using-api-cli-sdk"></a>

您可以使用`update-cluster` AWS CLI 命令更新现有集群的实例组，从而添加、更新或删除训练计划。以下示例说明如何更新集 SageMaker HyperPod 群并为实例组提供新的训练计划。

```
# Update a cluster
aws sagemaker update-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,\
        },\
        {\
            "InstanceCount": 1,\
            "InstanceGroupName": "worker-nodes-2",\
            "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,\
        }\
    ]'
