    10  
    11  Provides a ESS scaling group resource.
    12  
    13  ## Example Usage
    14  
    15  ```
    16  resource "alicloud_ess_scaling_group" "scaling" {
    17    min_size           = 1
    18    max_size           = 2
    19    removal_policies   = ["OldestInstance", "NewestInstance"]
    20  }
    21  ```
    22  
    23  ## Argument Reference
    24  
    25  The following arguments are supported:
    26  
    27  * `min_size` - (Required) Minimum number of ECS instances in the scaling group. Value range: [0, 100].
    28  * `max_size` - (Required) Maximum number of ECS instances in the scaling group. Value range: [0, 100].
    29  * `scaling_group_name` - (Optional) Name shown for the scaling group, which must contain 2-40 characters (English or Chinese). If this parameter is not specified, the default value is ScalingGroupId.
    30  * `default_cooldown` - (Optional) Default cool-down time (in seconds) of the scaling group. Value range: [0, 86400]. The default value is 300s.
    31  * `vswitch_id` - (Optional) The virtual switch ID which the ecs instance to be create in.
    32  * `removal_policies` - (Optional) RemovalPolicy is used to select the ECS instances you want to remove from the scaling group when multiple candidates for removal exist. Optional values:
    33      - OldestInstance: removes the first ECS instance attached to the scaling group.
    34      - NewestInstance: removes the first ECS instance attached to the scaling group.
    35      - OldestScalingConfiguration: removes the ECS instance with the oldest scaling configuration.
    36      - Default values: OldestScalingConfiguration and OldestInstance. You can enter up to two removal policies.
    37  * `db_instance_ids` - (Optional) If an RDS instance is specified in the scaling group, the scaling group automatically attaches the Intranet IP addresses of its ECS instances to the RDS access whitelist.
    38      - The specified RDS instance must be in running status.
    39      - The specified RDS instance’s whitelist must have room for more IP addresses.
    40  * `loadbalancer_ids` - (Optional) If a Server Load Balancer instance is specified in the scaling group, the scaling group automatically attaches its ECS instances to the Server Load Balancer instance.
    41      - The Server Load Balancer instance must be enabled.
    42      - Health check must be enabled for all listener ports configured for the Server Load Balancer instance; otherwise, creation fails.
    43      - The Server Load Balancer instance attached with VPC-type ECS instances cannot be attached to the scaling group.
    44      - The default weight of an ECS instance attached to the Server Load Balancer instance is 50.
