## Properties

- `appLifecycleManagement`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDomain.AppLifecycleManagementProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_sagemaker.CfnDomain.AppLifecycleManagementProperty.html) — Indicates whether idle shutdown is activated for JupyterLab applications.

- `builtInLifecycleConfigArn`: string — The lifecycle configuration that runs before the default lifecycle configuration.

  It can override changes made in the default lifecycle configuration.

- `codeRepositories`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDomain.CodeRepositoryProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_sagemaker.CfnDomain.CodeRepositoryProperty.html)[] — A list of Git repositories that SageMaker automatically displays to users for cloning in the JupyterLab application.

- `customImages`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDomain.CustomImageProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_sagemaker.CfnDomain.CustomImageProperty.html)[] — A list of custom SageMaker images that are configured to run as a JupyterLab app.

- `defaultResourceSpec`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnDomain.ResourceSpecProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_sagemaker.CfnDomain.ResourceSpecProperty.html) — The default instance type and the Amazon Resource Name (ARN) of the default SageMaker image used by the JupyterLab app.

- `lifecycleConfigArns`: string[] — The Amazon Resource Name (ARN) of the lifecycle configurations attached to the user profile or domain.

  To remove a lifecycle config, you must set `LifecycleConfigArns` to an empty list.
