使用条件键

您可以指定决定IAM策略如何生效的条件。在中 ElastiCache，您可以使用JSON策略Condition元素将请求上下文中的密钥与您在策略中指定的密钥值进行比较。有关更多信息，请参阅IAMJSON策略元素：条件。

要查看 ElastiCache 条件密钥列表，请参阅《服务授权参考》 ElastiCache中的 Amazon 条件密钥。

指定条件：使用条件键

要实现精细控制，您需要编写一个IAM权限策略，该策略指定了控制特定请求上的一组单个参数的条件。然后，您可以将该策略应用于使用IAM控制台创建的IAM用户、群组或角色。

要应用条件，请将条件信息添加到IAM策略声明中。在以下示例中，您指定了条件，为创建的所有自行设计缓存群集使用节点类型 cache.r5.large。

以下显示了使用 Valkey 或 Redis OSS 时此权限策略的示例。

}

在CreateReplicationGroup操作策略true中将elasticache:TransitEncryptionEnabled条件键设置为时，只有在CreateReplicationGroup请求中包含设置为的参数true和设置为的TransitEncryptionEnabled参数时，TransitEncryptionMode才允许请求required。

elasticache:TransitEncryptionEnabled将trueModifyReplicationGroup操作设置为，以指定只有在使用复制组TLS时才能修改：
