Delete an Amazon SageMaker Domain

A domain consists of a list of authorized users, configuration settings, and an Amazon Elastic File System (Amazon EFS) volume, which contains data for the users, including notebooks, resources, and artifacts. A user can have multiple applications (apps) which support the reading and execution experience of the user’s notebooks, terminals, and consoles.

You can delete your domain using one of the following:

• AWS console

• AWS Command Line Interface (AWS CLI)

• SageMaker SDK

The following sections give information on the requirements to delete a domain, as well as how to delete the domain.

Requirements

You must satisfy the following requirements to delete a domain.

• You must have admin permission to delete a Domain.

• You can only delete an app whose status is InService, which is displayed as Ready in the domain. An app whose status is Failed doesn't need to be deleted to delete the containing domain. In the domain, an attempt to delete an app in the failed state results in an error.

• To delete a domain, the domain cannot contain any user profiles. To delete a user profile, the profile cannot contain any non-failed apps.

  When you delete these resources, the following occurs:

  • App – The data (files and notebooks) in a user's home directory is saved. Unsaved notebook data is lost.

  • User profile – The user is no longer able to sign in to the Domain and loses access to their home directory, but the data is not deleted. An admin can retrieve the data from the Amazon EFS volume where it is stored under the user's AWS account.

• You must delete the domain if you want to switch authentication modes from IAM to IAM Identity Center.

EFS files

Your files are kept in an Amazon EFS volume as a backup. This backup includes the files in the mounted directory, which is /home/sagemaker-user for Jupyter and /root for your kernel. When you delete files from these mounted directories, the kernel or app may move the deleted files into a hidden trash folder. If the trash folder is inside the mounted directory, those files are copied into the Amazon EFS volume and will incur charges. To avoid these Amazon EFS charges, you must identify and clean the trash folder location. The trash folder location for default apps and kernels is ~/.local/. This may vary depending on the Linux distribution used for custom apps or kernels. For more information about the Amazon EFS volume, see Manage Your EFS Storage Volume in SageMaker Studio.

When you use the AWS console to delete the domain, the Amazon EFS volume is detached but not deleted. The same behavior occurs by default when you use the AWS CLI or the SDK to delete the domain. However, when you use the AWS CLI or the SDK, you can set the RetentionPolicy to HomeEfsFileSystem=Delete to delete the EFS volume along with the domain.

Delete a Amazon SageMaker Domain (Console)

To delete a domain

1. Open the SageMaker console.

2. Choose Control Panel on the left side of the page.

3. Repeat the following steps for each user in the User name list.

   1. Choose the user.

   2. On the User Details page, for each non-failed app in the Apps list, choose Action.

   3. From the dropdown list, choose Delete.

   4. On the Delete app dialog, choose Yes, delete app, type delete in the confirmation field, and then choose Delete.

   5. When the Status for all apps show as Deleted, choose Edit.

   6. From the Edit User page, choose Delete user.

   7. On the Delete user dialog, choose Yes, delete user, type delete in the confirmation field, and then choose Delete.

   Important

   When a user is deleted, they lose access to the Amazon EFS volume that contains their data, including notebooks and other artifacts. The data is not deleted and can be accessed by an administrator.

4. When all users are deleted, choose the domain settings icon ( ).

5. From the General settings page, choose Delete Domain.

6. On the Delete Domain dialog, choose Yes, delete Domain, type delete in the confirmation field, and then choose Delete.

Delete a Amazon SageMaker Domain (CLI)

To delete a domain

1. Retrieve the list of domains in your account.

   aws --region Region sagemaker list-domains

2. Retrieve the list of applications for the domain to be deleted.

   aws --region Region sagemaker list-apps \
       --domain-id-equals DomainId

3. Delete each application in the list.

   aws --region Region sagemaker delete-app \
       --domain-id DomainId \
       --app-name AppName \
       --app-type AppType \
       --user-profile-name UserProfileName

4. Retrieve the list of user profiles in the domain.

   aws --region Region sagemaker list-user-profiles \
       --domain-id-equals DomainId

5. Delete each user profile in the list.

   aws --region Region sagemaker delete-user-profile \
       --domain-id DomainId \
       --user-profile-name UserProfileName

6. Delete the domain. To also delete the Amazon EFS volume, specify HomeEfsFileSystem=Delete.

   aws --region Region sagemaker delete-domain \
       --domain-id DomainId \
       --retention-policy HomeEfsFileSystem=Retain
