Response Structure

  • (dict) –

    • NodeDetails (dict) –

      The details of the instance.

      • InstanceGroupName (string) –

        The instance group name in which the instance is.

      • InstanceId (string) –

        The ID of the instance.

      • InstanceStatus (dict) –

        The status of the instance.

        • Status (string) –

          The status of an instance in a SageMaker HyperPod cluster.

        • Message (string) –

          The message from an instance in a SageMaker HyperPod cluster.

      • InstanceType (string) –

        The type of the instance.

      • LaunchTime (datetime) –

        The time when the instance is launched.

      • LifeCycleConfig (dict) –

        The LifeCycle configuration applied to the instance.

        • SourceS3Uri (string) –

          An Amazon S3 bucket path where your lifecycle scripts are stored.

          Warning

          Make sure that the S3 bucket path starts with s3://sagemaker-. The IAM role for SageMaker HyperPod has the managed AmazonSageMakerClusterInstanceRolePolicy attached, which allows access to S3 buckets with the specific prefix sagemaker-.

        • OnCreate (string) –

          The file name of the entrypoint script of lifecycle scripts under SourceS3Uri. This entrypoint script runs during cluster creation.

      • ThreadsPerCore (integer) –

        The number of threads per CPU core you specified under CreateCluster.
