Argument Reference

The following arguments are supported:

  • launch_template_id - (Required, ForceNew) The ID of the instance launch template associated with the auto provisioning group.
  • total_target_capacity - (Required) The total target capacity of the auto provisioning group. The target capacity consists of the following three parts:PayAsYouGoTargetCapacity,SpotTargetCapacity and the supplemental capacity besides PayAsYouGoTargetCapacity and SpotTargetCapacity.
  • auto_provisioning_group_name - (Optional) The name of the auto provisioning group to be created. It must be 2 to 128 characters in length. It must start with a letter but cannot start with http:// or https://. It can contain letters, digits, colons (:), underscores (_), and hyphens (-)
  • auto_provisioning_group_type - (Optional, ForceNew) The type of the auto provisioning group. Valid values:request and maintain,Default value: maintain.
  • spot_allocation_strategy - (Optional, ForceNew) The scale-out policy for preemptible instances. Valid values:lowest-price and diversified,Default value: lowest-price.
  • spot_target_capacity - (Optional) The target capacity of preemptible instances in the auto provisioning group.
  • spot_instance_interruption_behavior - (Optional, ForceNew) The default behavior after preemptible instances are shut down. Valid values: stop and terminate,Default value: stop.
  • spot_instance_pools_to_use_count - (Optional, ForceNew) This parameter takes effect when the SpotAllocationStrategy parameter is set to lowest-price. The auto provisioning group selects instance types of the lowest cost to create instances.
  • pay_as_you_go_allocation_strategy - (Optional, ForceNew) The scale-out policy for pay-as-you-go instances. Valid values: lowest-price and prioritized,Default value: lowest-price.
  • pay_as_you_go_target_capacity - (Optional) The target capacity of pay-as-you-go instances in the auto provisioning group.
  • default_target_capacity_type - (Optional) The type of supplemental instances. When the total value of PayAsYouGoTargetCapacity and SpotTargetCapacity is smaller than the value of TotalTargetCapacity, the auto provisioning group will create instances of the specified type to meet the capacity requirements. Valid values:PayAsYouGo: Pay-as-you-go instances; Spot: Preemptible instances, Default value: Spot.
  • launch_template_version - (Optional, ForceNew) The version of the instance launch template associated with the auto provisioning group.
  • excess_capacity_termination_policy - (Optional) The shutdown policy for excess preemptible instances followed when the capacity of the auto provisioning group exceeds the target capacity. Valid values: no-termination and termination,Default value: no-termination.
  • terminate_instances_with_expiration - (Optional) The shutdown policy for preemptible instances when the auto provisioning group expires. Valid values: false and true, default value: false.
  • terminate_instances - (Optional, ForceNew) Specifies whether to release instances of the auto provisioning group. Valid values:false and true, default value: false.
  • description - (Optional, ForceNew) The description of the auto provisioning group.
  • max_spot_price - (Optional) The global maximum price for preemptible instances in the auto provisioning group. If both the MaxSpotPrice and LaunchTemplateConfig.N.MaxPrice parameters are specified, the maximum price is the lower value of the two.
  • valid_from - (Optional, ForceNew) The time when the auto provisioning group is started. The period of time between this point in time and the point in time specified by the valid_until parameter is the effective time period of the auto provisioning group.By default, an auto provisioning group is immediately started after creation.
  • valid_until - (Optional, ForceNew) The time when the auto provisioning group expires. The period of time between this point in time and the point in time specified by the valid_from parameter is the effective time period of the auto provisioning group.By default, an auto provisioning group never expires.
  • launch_template_config - (Required, ForceNew) DataDisk mappings to attach to ecs instance. See block-config below for details.

block-config

The config mapping supports the following:

  • instance_type - (Optional) The instance type of the Nth extended configurations of the launch template.
  • max_price - (Required) The maximum price of the instance type specified in the Nth extended configurations of the launch template.
  • vswitch_id - (Required) The ID of the VSwitch in the Nth extended configurations of the launch template.
  • weighted_capacity - (Required) The weight of the instance type specified in the Nth extended configurations of the launch template.
  • priority - (Optional) The priority of the instance type specified in the Nth extended configurations of the launch template. A value of 0 indicates the highest priority.
