# UpdateNotebookInstanceLifecycleConfig
<a name="API_UpdateNotebookInstanceLifecycleConfig"></a>

Updates a notebook instance lifecycle configuration created with the [CreateNotebookInstanceLifecycleConfig](https://docs.amazonaws.cn/sagemaker/latest/APIReference/API_CreateNotebookInstanceLifecycleConfig.html) API.

**Note**  
Updates to lifecycle configurations affect all notebook instances using that configuration upon their next start. Lifecycle configuration scripts execute with root access and the notebook instance's IAM execution role privileges. Grant this permission only to trusted principals. See [Customize a Notebook Instance Using a Lifecycle Configuration Script](https://docs.amazonaws.cn/sagemaker/latest/dg/notebook-lifecycle-config.html) for security best practices.
