如何使用terraform将浮动ip地址与openstack中的实例关联起来

Question

我使用terraform在openstack中创建了两个实例，并且我希望在不需要任何手动干预的情况下自动为它们分配浮动ip地址。

我的.tf文件如下所示：

resource "openstack_networking_floatingip_v2" "floating-ip" {
 count  = 4
 pool = "floating-ip-pool" 
}

resource "openstack_compute_floatingip_associate_v2" "fip-associate" {
floating_ip = openstack_networking_floatingip_v2.floating-ip.address[count.0]
instance_id = openstack_compute_instance_v2.terraform-vm.id[count.0]
}`

我搞错了

“错误:缺少资源实例键

在Imag-Provisioning.tf第33行中，在资源"openstack_compute_floatingip_associate_v2“”fip-associate“中: 33: instance_id =

我的terraform版本是: Terraform v0.12.24 + provider.openstack 1.26.0。

能够在地形中使用for_each选项解析：

resource "openstack_compute_instance_v2" "terraform_vm" {

  image_id        = "f8b9189d-2518-4a32-b1ba-2046ea8d47fd"
  for_each        =  var.instance_name
  name            =  each.key
  flavor_id       = "3"
  key_pair        = "openstack vm key"
  security_groups = ["default"]

 network {
  name = "webapps-network"
 }
 }

resource "openstack_networking_floatingip_v2" "floating_ip" {
pool = "floating-ip-pool"
for_each        =  var.instance_name

}

resource "openstack_compute_floatingip_associate_v2" "fip_associate" {
for_each        =  var.instance_name
floating_ip = openstack_networking_floatingip_v2.floating_ip[each.key].address
instance_id = openstack_compute_instance_v2.terraform_vm[each.key].id
}
