AliyunServiceRolePolicyForECSImageBuilder is the authorization policy dedicated to a service-linked role. The policy is automatically attached to a service role when the service role is created. Then, the service-linked role is authorized to access other cloud services. This policy is updated by the relevant Alibaba Cloud service. Do not attach this policy to a RAM identity other than a service-linked role.
