具有多个磁盘GCP的Terraform多个虚拟机
我正在尝试创建虚拟机列表，每个虚拟机都有需要创建和附加的磁盘列表。
在下面的示例中，我必须使用3个磁盘test-d01-data和test-d01-data-disk创建test-d01Compute，并使用2个磁盘test-d02-data-01和test-d02-data-02创建test-d01-commitlog-disk。
例如，下面的示例中，VM_info表示所需的配置，它将
{
name = "test-d01"
zone = "us-east1-b"
disk = [
{
disk_name = "test-d01-data"
disk_type = "pd-ssd"
disk_size = "60"
},
{
disk_name = "test-d01-data-disk"
disk_type = "pd-standard"
disk_size = "15"
},
{
disk_name = "test-d01-commitlog-disk"
disk_type = "pd-ssd"
disk_size = "30"
}
]
},
{
name = "test-d02"
zone = "us-east1-b"
disk=[
{
disk_name = "test-d02-data"
disk_type = "pd-ssd"
disk_size = "60"
},
{
disk_name = "test-d02-data-disk"
disk_type = "pd-standard"
disk_size = "15"
}
]
},

好主意。当我使用这个的时候，我得到了一个
terraform plan
var.disks
Enter a value: 2
var.instance_name
Enter a value: DDVE5

可以使用计算实例配置中的attached_disk部分将
永久磁盘连接到计算实例。但是，在某些情况下，通过计算实例配置来管理所连接的磁盘是不可取或不可能的，例如使用
count变量来连接动态磁盘数量。
因此，创建具有attached_disk属性的google_compute_instance的简单方法在这种情况下可能不适用。
简而言之，这个想法是首先创建持久磁盘，然后创建VM实例，并将新磁盘附加到新创建的实例。此测试部署由根配置文件my_instances.tf和可重用模块./instance/main.tf组成。
1.可以独立创建 Persistent disks google_compute_disk。为了简单起见，根文件my_instances.tf中使用了5个文字块。
2.调用可重用模块instance/main.tf，并将VM属性和磁盘列表传递给该模块，以便：
binding objects Create a VM instance google_compute_instance;
- Use
-
google_compute_attached_disk将新的空磁盘附加到新创建的VM实例。
要处理磁盘列表，需要使用for_each元参数。
由于for_each只接受一个映射或一组字符串，因此toset函数用于将磁盘列表转换为一组磁盘。

您还可以使用以下命令获得附加的磁盘：
resource "google_compute_disk" "default" {
name = "test-disk"
type = "pd-ssd"
zone = var.instance_zone
# image = "debian-9-stretch-v20200805"
labels = {
environment = "dev"
}
physical_block_size_bytes = 4096
}
resource "google_compute_attached_disk" "vm_attached_disk" {
count = var.disks
disk = google_compute_disk.default.id
instance = google_compute_instance.vm-instance.id
