如何将静态 IP 映射到 terraform google 计算引擎实例？答案

【问题描述】：

我将 terraform 与 google vm 提供程序一起使用。我想将现有的静态 IP 分配给 VM。

代码：

resource "google_compute_instance" "test2" {
  name         = "dns-proxy-nfs"
  machine_type = "n1-standard-1"
  zone         = "${var.region}"

  disk {
    image = "centos-7-v20170719"
  }

  metadata {
    ssh-keys = "myuser:${file("~/.ssh/id_rsa.pub")}"
  }

  network_interface {
    network = "default"
    access_config {
      address = "130.251.4.123"
    }
  }
}

但它因错误而失败：

google_compute_instance.test2：network_interface.0.access_config.0：无效或未知密钥：地址

我该如何解决这个问题？

【解决方案1】：

您还可以允许 terraform 为您创建静态 IP 地址，然后按对象名称将其分配给实例。

resource "google_compute_address" "test-static-ip-address" {
  name = "my-test-static-ip-address"
}

resource "google_compute_instance" "test2" {
  name         = "dns-proxy-nfs"
  machine_type = "n1-standard-1"
  zone         = "${var.region}"

  disk {
    image = "centos-7-v20170719"
  }

  metadata {
    ssh-keys = "myuser:${file("~/.ssh/id_rsa.pub")}"
  }

  network_interface {
    network = "default"
    access_config {
      nat_ip = "${google_compute_address.test-static-ip-address.address}"
    }
  }
}

你知道我为什么会收到这个错误吗？错误：错误创建地址：googleapi：错误 409：资源 'projects/XXX/regions/europe-west1/addresses/my-test-static-ip-address' 已经存在，已经存在
我找到了解决方案：terraform import google_compute_address.static my-test-static-ip-address

【解决方案2】：

它通过在access_config 中将address 更改为nat_ip 来工作。

resource "google_compute_instance" "test2" {
  name         = "dns-proxy-nfs"
  machine_type = "n1-standard-1"
  zone         = "${var.region}"

  disk {
    image = "centos-7-v20170719"
  }

  metadata {
    ssh-keys = "myuser:${file("~/.ssh/id_rsa.pub")}"
  }

  network_interface {
    network = "default"
    access_config {
      nat_ip = "130.251.4.123" // this adds regional static ip to VM
    }
  }
}
