我一直在尝试使用 terraform 启动不同图像的多个实例，但到目前为止还没有运气。我可以使用count. 在使用 旋转不同的图像时for_each，我无法获得正确的配置。

我有以下变量 .tf 配置文件。

variable "images" {
  type = map
  default = {
    "rhel-8-factory-os-ready" = {
       "az_zone" = "eu-fra-1ah"
       "ins_count" = 2
     }
    "rhel-7-factory-os-ready" = {
       "az_zone" = "eu-fra-1ai"
       "ins_count" = 2
    }
  }
}

resource "openstack_compute_instance_v2" "instance" {
   for_each = var.images
   flavor_id = var.flavor
   image_name = each.key
   name = "${var.image_name}-${lower(random_id.random-instance.hex)}"
   availability_zone = each.value.az_zone
   security_groups = var.security_group
   key_pair = "fop-mgt-key"
   network {
     name = var.network_name
   }
}

resource "random_id" "random-instance" {
  byte_length = 4
}

resource "random_id" "random-number" {
  byte_length = 8
}

resource "openstack_networking_floatingip_v2" "fip" {
  count = length(var.images)
  pool = var.floatingip_pool
}

resource "openstack_compute_floatingip_associate_v2" "fip" {

  depends_on = [openstack_compute_instance_v2.instance]

  count = length(var.images)
  floating_ip = openstack_networking_floatingip_v2.fip[count.index].address
  instance_id = openstack_compute_instance_v2.instance.*.id[count.index]
  fixed_ip    = openstack_compute_instance_v2.instance.*.network.0.fixed_ip_v4[count.index]
}

terraform {
  backend "artifactory" {}
}

data "terraform_remote_state" "foo" {
  backend = "artifactory"
  config = {
    repo = "${var.repo}"
    subpath = "${var.subpath}"
  }
}

我看到以下错误消息::

错误：不支持的属性

在 tf-backend-fra/main.tf 第 49 行，在资源“openstack_compute_floatingip_associate_v2”“fip”中：49：instance_id = openstack_compute_instance_v2.instance.*.id[count.index]

此对象没有名为“id”的属性。

我不知道如何完成它for_each。Terraform 版本是 0.12.17。非常感谢您的帮助。

谢谢，哈沙

不知何故设法解决了lookup下面element的问题。

resource "openstack_compute_instance_v2" "instance" {
   for_each = var.images
   flavor_id = each.value.flavor
   image_id = lookup(data.openstack_images_image_v2.os-image, each.key).id
   name = "${var.image_name}-${lower(random_id.random-instance.hex)}"
   availability_zone = each.value.az_zone
   security_groups = var.security_group
   key_pair = "fop-mgt-key"
   network {
     name = var.network_name
   }
}

resource "openstack_compute_floatingip_associate_v2" "fip" {
  for_each = var.images
  floating_ip = element(openstack_networking_floatingip_v2.fip, index(tolist(keys(var.images)), each.key)).address
  instance_id = lookup(openstack_compute_instance_v2.instance, each.key).id
  fixed_ip    = lookup(openstack_compute_instance_v2.instance, each.key).network.0.fixed_ip_v4
}
