Update a SageMaker HyperPod cluster on training plans using the SageMaker API, or AWS CLI

You can add, update, or remove a training plan by updating the instance group of an existing cluster using the update-cluster AWS CLI command. The following sample illustrates how to update a SageMaker HyperPod cluster and provide an instance group with a new training plan.

# 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,\
        }\
    ]'
