Scenarios and deletion of the service-linked role for VPC access - Container Registry

When you import images from a Container Registry Personal Edition instance to a Container Registry Enterprise Edition instance, the system automatically creates a service-linked role named AliyunServiceRoleForContainerRegistryConnectCustomerVPC to access the Virtual Private Cloud (VPC). This topic describes the scenarios of the service-linked role and how to delete this role.

Scenarios

To import images from Container Registry, you must use a VPC to migrate image data. Container Registry must have VPC access to transfer image data when you import images. The system automatically creates a service-linked role named AliyunServiceRoleForContainerRegistryConnectCustomerVPC when you import images from a Container Registry Personal Edition instance to a Container Registry Enterprise Edition instance. Container Registry assumes this role to access resources in the VPC where the instances are deployed.

FAQ

Why is the AliyunServiceRoleForContainerRegistryConnectCustomerVPC service-linked role not automatically created for a RAM user?

The system automatically creates the AliyunServiceRoleForContainerRegistryConnectCustomerVPC role for RAM users that are granted with specific permissions. If the AliyunServiceRoleForContainerRegistryConnectCustomerVPC role is not automatically created, you must attach the following policy to the RAM user.
