google-cloud-platform - 无法使用 Terraform 创建具有静态 IP 的 GCE 实例

Question

我正在尝试创建一个具有静态外部 IP 地址的 GCE 实例，该地址将在机器的生命周期后持续存在。

我有两个独立的 terraform 目录。

(1) 创建 IP 地址:

# project_ips/ip.tf

locals {
  project_id             = "my_project"
  region                 = "my-region"
  static_ip_address_name  = "my-address"

}

module "address-fe" {
  source       = "terraform-google-modules/address/google"
  version      = "~> 3.1"
  project_id   = local.project_id
  region       = local.region
  address_type = "EXTERNAL"
  names = [
    local.static_ip_address_name,
  ]
  global = true
}

(2) 创建虚拟机及其网络:

# project_vm/networks.tf

# ...
# code where network and subnetwork are created 
# ...

data "google_compute_address" "vm_address" {
  project = var.project_id
  region  = var.region
  name    = "my-address"
}

虚拟机:

# project_vm/neo4j.tf

resource "google_compute_instance" "vm" {
  project      = var.project_id
  name         = "my-instance"
  machine_type = var.machine_type
  zone         = var.zone

  network_interface {
    subnetwork_project = var.project_id
    subnetwork         = google_compute_subnetwork.public_subnet.name
    access_config {
      nat_ip = data.google_compute_address.vm_address.address
    }
  }
}

但是，当创建机器时，它会被分配一个新的临时 IP 地址，而不是在其他项目中创建的 IP 地址，并且可能是通过数据 block 传递的。这里缺少什么？

Answer 1

您可能需要使用 resource 子句创建地址，而不是使用 data 子句获取有关该地址的信息(请参阅您的代码)。

所以，而不是

data "google_compute_address" "vm_address" {
  project = var.project_id
  region  = var.region
  name    = "my-address"
}

你可能需要类似的东西

resource "google_compute_address" "vm_address" {
  project      = var.project_id
  address_type = "EXTERNAL"
  network_tier = "PREMIUM"
  region       = var.region
  name         = "some name"
  description  = "An external IP address for my virtual machine"
}

并在network_interface部分中使用它:

nat_ip = google_compute_address.vm_address.address

上面的子句中不需要 data 前缀。请参阅此处的 Terraform 文档和示例:google_compute_address
