本文为您介绍弹性容器实例服务关联角色AliyunServiceRoleForECI以及如何删除服务关联角色。

背景信息

弹性容器实例服务关联角色AliyunServiceRoleForECI是ECI在某些情况下，为了完成自身的某个功能，需要获取其他云服务的访问权限而提供的RAM角色。更多关于服务关联角色的信息，请参见服务关联角色。

AliyunServiceRoleForECI应用场景

在创建ECI实例和镜像缓存的过程中，ECI需要访问云服务器ECS、专有网络VPC、容器镜像服务ACR、日志服务SLS和负载均衡SLB的资源时，可以通过自动创建的弹性容器实例服务关联角色AliyunServiceRoleForECI获取访问权限。
