镜像服务 IMS-IMS自定义策略:策略样例
策略样例
- 示例1:授权用户制作镜像
{ "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "ims:serverImages:create" ] }, { "Effect": "Allow", "Action": [ "KMS:*:*" ] }, { "Effect": "Allow", "Action": [ "ecs:cloudServers:get", "ecs:servers:get", "ecs:serverVolumes:use", "ecs:cloudServers:list", "ecs:serverVolumeAttachments:list", "ecs:servers:list" ] }, { "Effect": "Allow", "Action": [ "bms:servers:list", "bms:servers:get", "bms:serverFlavors:get" ] }, { "Effect": "Allow", "Action": [ "evs:volumes:*" ] } ] } { "Version": "1.1", "Statement": [ { "Effect": "Allow", "Action": [ "OBS:*:*" ] } ] }
制作镜像对应的授权项为:ims:serverImages:create,其他授权项均为制作镜像所依赖的授权项。
- 示例2:拒绝用户删除镜像
拒绝策略需要同时配合其他策略使用,否则没有实际作用。用户被授予的策略中,一个授权项的作用如果同时存在Allow和Deny,则遵循Deny优先原则。
如果您给用户授予IMS FullAccess的系统策略,但不希望用户拥有IMS FullAccess中定义的删除镜像权限,您可以创建一条拒绝删除镜像的自定义策略,然后同时将IMS FullAccess和拒绝策略授予用户,根据Deny优先原则,则用户可以对IMS执行除了删除镜像外的所有操作。拒绝策略示例如下:
{ "Version": "1.1", "Statement": [ { "Effect": "Deny", "Action": [ "ims:images:delete" ] } ] }
