Set default lifecycle configurations

Important

As of November 30, 2023, the previous Amazon SageMaker Studio experience is now named Amazon SageMaker Studio Classic. The following section is specific to using the Studio Classic application. For information about using the updated Studio experience, see Amazon SageMaker Studio.

Although you can attach multiple lifecycle configuration scripts to a single resource, you can only set one default lifecycle configuration for each JupyterServer or KernelGateway application. The behavior of the default lifecycle configuration depends on whether it is set for JupyterServer or KernelGateway apps.

  • JupyterServer apps: When set as the default lifecycle configuration script for JupyterServer apps, the lifecycle configuration script runs automatically when the user signs in to Studio Classic for the first time or restarts Studio Classic. Use this default lifecycle configuration to automate one-time setup actions for the Studio Classic developer environment, such as installing notebook extensions or setting up a GitHub repo. For an example of this, see Customize Amazon SageMaker Studio using Lifecycle Configurations.

  • KernelGateway apps: When set as the default lifecycle configuration script for KernelGateway apps, the lifecycle configuration is selected by default in the Studio Classic launcher. Users can launch a notebook or terminal with the default script selected, or they can select a different one from the list of lifecycle configurations.

SageMaker supports setting a default lifecycle configuration for the following resources:

  • Domains

  • User profiles

  • Shared spaces

While domains and user profiles support setting a default lifecycle configuration from both the Amazon SageMaker console and Amazon Command Line Interface, shared spaces only support setting a default lifecycle configuration from the Amazon CLI.

You can set a lifecycle configuration as the default when creating a new resource or updating an existing resource. The following topics demonstrate how to set a default lifecycle configuration using the SageMaker console and Amazon CLI.

Default lifecycle configuration inheritance

Default lifecycle configurations set at the domain level are inherited by all users and shared spaces. Default lifecycle configurations set at the user and shared space level are scoped to only that user or shared space. User and space defaults override defaults set at the domain level.

A default KernelGateway lifecycle configuration set for a domain applies to all KernelGateway applications launched in the domain. Unless the user selects a different lifecycle configuration from the list presented in the Studio Classic launcher, the default lifecycle configuration is used. The default script also runs if No Script is selected by the user. For more information about selecting a script, see Step 3: Launch an application with the lifecycle configuration.
