试图找到如何从同一模板创建具有静态外部IP的两个GCP实例的方法。我有一个代码，在两个非托管实例组中创建两个具有临时外部IP的实例。我需要改进与静态外部IP创建实例的代码。现有代码:
resource "google_compute_instance_template" "default" {
# name = format("%s-template", var.hostname)
name_prefix = var.hostname

machine_type = var.machine_type

disk {
auto_delete = lookup(var.main_disk, "auto_delete", true)
boot = true
source_image = lookup(var.main_disk, "source_image", "projects/debian-cloud/global/images/family/debian-9")
device_name = lookup(var.main_disk, "device_name", null)
mode = lookup(var.main_disk, "device_name", "READ_WRITE")
type = lookup(var.main_disk, "type", "PERSISTENT")
disk_name = lookup(var.main_disk, "disk_name", null)
disk_type = lookup(var.main_disk, "disk_type", "pd-ssd")
disk_size_gb = lookup(var.main_disk, "disk_size_gb", null)
}
dynamic "disk" {
for_each = [for d in var.additional_disks : {
# auto_delete - (Optional) Whether or not the disk should be auto-deleted. This defaults to true.
auto_delete = lookup(d, "auto_delete", true)
# device_name - (Optional) A unique device name that is reflected into the /dev/ tree of a Linux operating system running within the instance. If not specified, the server chooses a default device name to apply to this disk.
device_name = lookup(d, "device_name", null)
# disk_name - (Optional) Name of the disk. When not provided, this defaults to the name of the instance.
disk_name = lookup(d, "disk_name", null)
# mode - (Optional) The mode in which to attach this disk, either READ_WRITE or READ_ONLY. If you are attaching or creating a boot disk, this must read-write mode.
mode = lookup(d, "mode", "READ_WRITE")
# source - (Required if source_image not set) The name (not self_link) of the disk (such as those managed by google_compute_disk) to attach.
source = d.source
# disk_type - (Optional) The GCE disk type. Can be either "pd-ssd", "local-ssd", or "pd-standard".
disk_type = lookup(d, "disk_type", "pd-ssd")
# disk_size_gb - (Optional) The size of the image in gigabytes. If not specified, it will inherit the size of its base image.
disk_size_gb = lookup(d, "disk_size_gb", null)
#type - (Optional) The type of GCE disk, can be either "SCRATCH" or "PERSISTENT".
type = lookup(d, "type", "PERSISTENT")

我找到了创建静态外部IP的模块
module "address" {
source = "terraform-google-modules/address/google"
version = "2.1.0"
project_id = var.project
region = var.region
address_type = "EXTERNAL"
enable_cloud_dns = false
names = [
"ip",
"ip2",
]
}
模块输出module.address.addresses格式
[
xxx.xxx.xxx.xxx,
yyy.yyy.yyy.yyy
]
但是我仍然找不到一个棘手的方法如何通过模板从模块获得这个IP的实例。
有谁能给我一些建议吗?
我对TF和GCP也相当陌生，但是…从脑海中浮现出两个想法(记住我是新手，可能是更好的解决方案)
- 用该值为每个IP定义一个变量，然后在你想要的资源中调用该IP。
- 为IP声明和输出，然后在资源中调用这些IP的输出，如IP
我通过覆盖模板设置解决了这个问题
resource "google_compute_address" "static" {
count = var.num_instances
project = var.project
name = var.ext_ip_name[count.index] # ["ip", "ip2"]
address_type = "EXTERNAL"
}

resource "google_compute_instance_from_template" "compute_instance" {
count = var.num_instances
project = var.project
name = format("%s%d", var.hostname, count.index + 1)
zone = var.zone[count.index]
source_instance_template = google_compute_instance_template.default.self_link
dynamic "network_interface" {
for_each = [for n in var.interfaces : {
network = lookup(n, "network", null)
subnetwork = lookup(n, "subnetwork", null)
network_ip = lookup(n, "network_ip", null)
nat_ip = lookup(n, "nat_ip", null)
network_tier = lookup(n, "network_tier", "PREMIUM")
public_ip = lookup(n, "public_ip", false)
}]
content {
network = network_interface.value.network
subnetwork = network_interface.value.subnetwork
network_ip = network_interface.value.network_ip
dynamic "access_config" {
for_each = network_interface.value.public_ip == "true" ? list(0) : []
content {
nat_ip = google_compute_address.static[count.index].address
network_tier = network_interface.value.network_tier
}
}
}
}
