Scaling
Attaches/Detaches vserver groups to a specified scaling group.
NOTE: The load balancer of which vserver groups belongs to must be in
activestatus. NOTE: If scaling group's network type isVPC, the vserver groups must be in the sameVPC. NOTE: A scaling group can have at most 5 vserver groups attached by default. NOTE: Vserver groups and the default group of loadbalancer share the same backend server quota. NOTE: When attach vserver groups to scaling group, existing ECS instances will be added to vserver groups; Instead, ECS instances will be removed from vserver group when detach. NOTE: Detach action will be executed before attach action. NOTE: Vserver group is defined uniquely byloadbalancer_id,vserver_group_id,port. NOTE: Modifingweightattribute means detach vserver group first and then, attach with new weight parameter. NOTE: Resourcealicloud.ess.ScalingGroupVServerGroupsis available in 1.53.0+.

}Block vserver_group
the vserver_group supports the following:
loadbalancer_id- (Required) Loadbalancer server ID of VServer Group.vserver_attributes- (Required) A list of VServer Group attributes. See Block vserver_attribute below for details.
Block vserver_attribute
vserver_group_id- (Required) ID of VServer Group.port- (Required) - The port will be used for VServer Group backend server.weight- (Required) The weight of an ECS instance attached to the VServer Group.
Import
ESS vserver groups can be imported using the id, e.g.
$ pulumi import alicloud:ess/scalingGroupVServerGroups:ScalingGroupVServerGroups example abc123456
