Question

我正在使用terraform 0.11和aws提供程序。我使用hashicorp提供的模块terraform-aws-modules/autoscaling创建了大约20个ASG

ASG示例：

module "role_a" {
  source  = "terraform-aws-modules/autoscaling/aws"
  version = "2.8.0"

  name                      = "Role-A-ASG"
  image_id                  = "ami-123456"
  ...
  min_size                  = "1"
  desired_capacity          = "2"
  max_size                  = "3"
}

我知道我可以为20个ASG中的每一个定义20个aws_autoscaling_schedule资源。但是，我想知道是否有更简单的方法可以使用count技巧来做到这一点。

我定义了一个变量，该变量包含要将aws_autoscaling_schedule应用于的ASG列表。

asg_turn_off_morning = [ "asg_role_a" ]

但是我找不到在autoscaling_group_name

中引用ASG名称的方法。

resource "aws_autoscaling_schedule" "turn_off_morning" {
  count                  = "${length(var.asg_turn_off_morning)}"
  recurrence             = "0 7 * * *"
  scheduled_action_name  = "Turn off in the morning"
...

# interpolating the resource reference works ok, but
  autoscaling_group_name = "${module.role_a.this_autoscaling_group_name}"                            

# interpolating a string with the resource's name does not work
  autoscaling_group_name = "${join(".", list("module", "role_a", "this_autoscaling_group_name"))}"

# If it did I could eventually do something like:
# I know this is not valid HCL, I just want to show what I want to do
  autoscaling_group_name = "${join(".", list("module", ${element(var.asg_turn_off_morning, count.index)} , "this_autoscaling_group_name"))}"
}

是否有一种反向查询表可以将asg_role_a资源映射到其属性之一？

将一个terraform aws_autoscaling_schedule应用于多个ASG模块
