ALIYUN::ESS::LoadBalancerAttachment类型用于添加一个或多个负载均衡实例。

语法

{
  "Type": "ALIYUN::ESS::LoadBalancerAttachment",
  "Properties": {
    "ScalingGroupId": String,
    "ForceAttach": Boolean,
    "LoadBalancers": List,

}

属性

属性名称	类型	必须	允许更新	描述	约束
ScalingGroupId	String	是	否	伸缩组ID。	无
ForceAttach	Boolean	否	否	是否把当前伸缩组内的实例全部添加为负载均衡实例的后端服务器。	取值： true：添加。 false（默认值）：不添加。
LoadBalancers	List	否	否	需要绑定的负载均衡CLB（原SLB）实例的ID列表。	最多绑定5个负载均衡实例。
LoadBalancerConfigs	List	否	否	负载均衡配置列表。	更多信息，请参见LoadBalancerConfigs属性。

LoadBalancerConfigs语法

"LoadBalancerConfigs": [
  {
    "LoadBalancerId": String,
    "Weight": Integer
  }
]

LoadBalancerConfigs属性

属性名称	类型	必须	允许更新	描述	约束
LoadBalancerId	String	否	否	负载均衡CLB（原SLB）实例ID。	无
Weight	Integer	否	否	弹性伸缩将ECS实例添加到SLB服务器组后，ECS实例作为后端服务器的权重。	权重越高，ECS实例将被分配到越多的访问请求。如果权重为0，则ECS实例不会收到访问请求。取值范围：0~100。
