属性

属性名称 类型 必须 允许更新 描述 约束
ResourceGroupId String 资源组ID。
VSwitchId String 交换机ID。 必须为源负载均衡实例所属专有网络下的交换机。不指定该参数时,将使用源负载均衡实例的交换机。
SourceLoadBalancerId String 将要克隆的负载均衡实例ID。
BackendServersPolicy String 克隆策略,指定配置新负载均衡实例需要监听的ECS实例以及各ECS实例的权重。 取值:
  • clone(默认值):把源负载均衡实例中监听的ECS实例和权重配置全部克隆到新的负载均衡实例中。
  • empty:不给新的负载均衡实例添加任何ECS实例。
  • append:既克隆源负载均衡实例中监听的ECS实例和权重配置,也添加新的ECS实例和权重配置到新的负载均衡实例。
  • replace:只添加新的ECS实例列表和权重配置而不克隆源负载均衡实例所监听的ECS实例列表和权重配置。
BackendServers List 指定新添加的需要监听的ECS实例列表。 详情请参见BackendServers属性
LoadBalancerName String 负载均衡实例名称。 用户自定义字符串。长度为1~80个字符,可包含英文字母、数字、短划线(-)、正斜线(/)、英文句点(.)和下划线(_)。
Tags List SLB实例标签。 标签以键值对方式传入,最多可以设置5组标签。

详情请参见Tags属性

TagsPolicy String 标签策略。 取值:
  • clone:使用源负载均衡实例的标签。
  • empty(默认值):不设置标签。
  • append:保留源实例标签并添加新标签。
  • replace:添加新标签,不保留源实例标签 。
InstanceChargeType String 实例计费方式。 取值:
  • PayBySpec(默认值):按规格计费。
  • PayByCLCU:按量计费。
    说明 当PayType(实例付费模式)取值为PayOnDemand(按量付费)时,该参数生效。
LoadBalancerSpec String 负载均衡实例的规格。 取值:
  • slb.s1.small(默认值)
  • slb.s2.small
  • slb.s2.medium
  • slb.s3.small
  • slb.s3.medium
