Last updated at Posted at 2019-08-04

概要

dynamic blocksを用いたresourceの記述例と参考リンク

terraform初心者の自分為のdynamic blocksの書き方メモ

時間がある際に追記します

開発環境

  • OSX Mojave 10.14.4
  • terraform 0.12.5

dynamic blocks参考資料リンク

記述例

  • aws_autoscaling_policyのstep_adjustment
variable "asg_steps" {
  type = list(map(string))
  default = [
   {
     scaling_adjustment           = 1
     metric_interval_lower_bound  = 1
     metric_interval_upper_bound  = 1000
   },
   {
     scaling_adjustment           = 2
     metric_interval_lower_bound  = 1000
     metric_interval_upper_bound  = 2000
   },
   {
     scaling_adjustment           = 3
     metric_interval_lower_bound  = 2000
     metric_interval_upper_bound  = null
   },
  ]
}

resource "aws_autoscaling_policy" "asg_policy" {
  name                   = "auto scaling grouop policy"
  adjustment_type        = "ExactCapacity"
  autoscaling_group_name = aws_autoscaling_group.ecs_asg.name
  policy_type = "StepScaling"

  dynamic "step_adjustment" {
    for_each = var.asg_steps
    content {
      scaling_adjustment          = step_adjustment.value["scaling_adjustment"]
      metric_interval_lower_bound = step_adjustment.value["metric_interval_lower_bound"]
      metric_interval_upper_bound = step_adjustment.value["metric_interval_upper_bound"]
    }
  }
}

スキップする項目(metric_interval_upper_bound)は代入値を'null'にすることで書式を合わせてます
