# Create and attach lifecycle configurations in Studio
<a name="code-editor-use-lifecycle-configurations-studio-create"></a>

The following section provides AWS CLI commands to create a lifecycle configuration, attach a lifecycle configuration when creating a new user profile, and attach a lifecycle configuration when updating a user profile. For prerequisites and general steps on creating and attaching lifecycle configurations in Studio, see [Lifecycle configuration creation](jl-lcc-create.md). 

When creating your Studio lifecycle configuration with the `create-studio-lifecycle-config` command, be sure to specify that the `studio-lifecycle-config-app-type` is `CodeEditor`. The following example shows how to create a new Studio lifecycle configuration for your Code Editor application.

```
aws sagemaker create-studio-lifecycle-config \
--studio-lifecycle-config-name my-code-editor-lcc \
--studio-lifecycle-config-content $LCC_CONTENT \
--studio-lifecycle-config-app-type CodeEditor
```

Note the ARN of the newly created lifecycle configuration that is returned. When attaching a lifecycle configuration, provide this ARN within the `LifecycleConfigArns` list of `CodeEditorAppSettings`. 

You can attach a lifecycle configuration when creating a user profile or domain. The following example shows how to create a new user profile with the lifecycle configuration attached. You can also create a new domain with a lifecycle configuration attached by using the [create-domain](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/opensearch/create-domain.html) command.

```
# Create a new UserProfile
aws sagemaker create-user-profile \
--domain-id domain-id \
--user-profile-name user-profile-name \
--user-settings '{
"CodeEditorAppSettings": {
  "LifecycleConfigArns":
    [lifecycle-configuration-arn-list]
  }
}'
```

You can alternatively attach a lifecycle configuration when updating a user profile or domain. The following example shows how to update a user profile with the lifecycle configuration attached. You can also update a new domain with a lifecycle configuration attached by using the [update-domain](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/sagemaker/update-domain.html) command.

```
# Update a UserProfile
aws sagemaker update-user-profile \
--domain-id domain-id \
--user-profile-name user-profile-name \
--user-settings '{
"CodeEditorAppSettings": {
  "LifecycleConfigArns":
    [lifecycle-configuration-arn-list]
  }
}'
```
