- Type last changed: v2.251.0 · 24 Apr 2026

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_sagemaker as sagemaker } from 'aws-cdk-lib';
const clusterLifeCycleConfigProperty: sagemaker.CfnCluster.ClusterLifeCycleConfigProperty = {
  onCreate: 'onCreate',
  onInitComplete: 'onInitComplete',
  sourceS3Uri: 'sourceS3Uri',
};
```

## Properties

- `onCreate`: string — The file name of the entrypoint script of lifecycle scripts under `SourceS3Uri` .

  This entrypoint script runs during cluster creation.

- `onInitComplete`: string — The file name of the extension script under SourceS3Uri.

  This script runs after HyperPod configures the default software on the instance. Mutually exclusive with OnCreate.

- `sourceS3Uri`: string — An Amazon S3 bucket path where your lifecycle scripts are stored.

  > Make sure that the S3 bucket path starts with `s3://sagemaker-` . The [IAM role for SageMaker HyperPod](https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-hyperpod-prerequisites.html#sagemaker-hyperpod-prerequisites-iam-role-for-hyperpod) has the managed [`AmazonSageMakerClusterInstanceRolePolicy`](https://docs.aws.amazon.com/sagemaker/latest/dg/security-iam-awsmanpol-cluster.html) attached, which allows access to S3 buckets with the specific prefix `sagemaker-` .
