Service-linked role - Serverless App Engine

Serverless App Engine (SAE) assumes the service-linked role AliyunServiceRoleForSAE to obtain access permissions on other Alibaba Cloud resources. This topic describes the scenarios to which the SAE service-linked role is applicable. This topic also describes how to create and delete the service-linked role.

Definition

In some cases, SAE may need to access another Alibaba Cloud service to implement a feature. For example, if you want to obtain information about resources such as virtual private clouds (VPCs) when you create an application, you can use the service-linked AliyunServiceRoleForSAE role to obtain required permissions to access the related services such as VPC. A service-linked role simplifies the process to authorize a service to access other services and reduces the risks caused by human errors. The policy that is attached to a service-linked role is predefined by the linked service. You cannot modify or delete the policy. You cannot attach policies to or detach policies from a service-linked role. For more information, see Service-linked roles.

Create the service-linked role

SAE automatically creates the service-linked role. If you have not created the service-linked role, the Welcome to Serverless App Engine (SAE) dialog box appears when you log on to the SAE console. Click Confirm to create the service-linked role.

Note If you have not created the service-linked role, the Welcome to Serverless App Engine (SAE) dialog box is displayed each time you log on to the SAE console.

Delete the service-linked role

If you want to delete the service-linked role, you must first delete all applications that are deployed on SAE within the current Alibaba Cloud account.

Important

After the service-linked role is deleted, you can no longer use SAE. Proceed with caution.
If you still need to use SAE after you delete the service-linked role, log on to the SAE console to recreate the service-linked role. For more information, see Create the service-linked role.

For information about how to delete applications, see Delete an application.
For information about how to delete the service-linked role, see Delete a RAM role.
