遍历服务器列表并为每个服务器创建警报？

问题描述

我有一个服务器列表，如下所示，我需要为其创建 cloudwatch 警报。我似乎找不到很多这样的例子。

variable "vms" {

type = list

default = ["server1","server2","server3"]

}

我想将 for_each 用于我的 cloudwatch 警报：

resource "aws_cloudwatch_metric_alarm" "ec2-warning" {

count = length(var.vms)

for_each = {for vms in var.vms: vm.host => vms}

alarm_name = 

comparison_operator = "GreaterThanThreshold"

evaluation_periods = "1"

metric_name = "disk_used_percent"

namespace = "CWAgent"

dimensions = {

path = "/"

fstype = "xfs"

host = data.aws_instance.myec2.private_

dnsdevice = "xvda1"

}

编辑：我相信我需要做这样的事情

locals {
  my_list = [
    "server1","server3","server4"
  ]
}

resource "aws_cloudwatch_metric_alarm" "ec2-disk-space-warning-for" {
  for_each = toset(local.my_list)
  alarm_name          = {each.key}-"ec2-disk-space-warning"
  comparison_operator = "GreaterThanThreshold"
  evaluation_periods  = "1"
  metric_name         = "disk_used_percent"
  namespace           = "CWAgent"
  dimensions = {
    path   = "/"
    fstype = "xfs"
    host   = {each.key}
    device = "xvda1"
  }
