我不确定如何在模块中引用一个Azure网络安全组。我创建了一个模块,可以对创建的任何VM重新使用,该模块在一定程度上可以正常工作,除非我不确定如何为其分配网络安全组ID。下面是一个示例(稍作修改,我身上没有),非常接近我所拥有的基础。
main.tf根目录
module "vm1" {
source = "/modules/vm/"
NSG = ????
}
tfvars
nic_name = apache_vm_nic
location = West Europe
........
modules / vm / main.tf
.........
resource "azurerm_network_interface" "myterraformnic" {
name = "var.nic_name"
location = "var.location"
resource_group_name = "${azurerm_resource_group.myterraformgroup.name}"
network_security_group_id = { WHAT DO I PUT HERE? }
ip_configuration {
name = "myNicConfiguration"
subnet_id = "${azurerm_subnet.myterraformsubnet.id}"
private_ip_address_allocation = "dynamic"
public_ip_address_id = "${azurerm_public_ip.myterraformpublicip.id}"
}
}
resource "azurerm_network_security_group" "apache-nsg" {
name = "myNetworkSecurityGroup"
location = "eastus"
resource_group_name = "${azurerm_resource_group.myterraformgroup.name}"
security_rule {
name = "SSH"
priority = 1001
direction = "Inbound"
access = "Allow"
protocol = "Tcp"
source_port_range = "*"
destination_port_range = "22"
source_address_prefix = "*"
destination_address_prefix = "*"
}
}
resource "azurerm_network_security_group" "nginx-nsg" {
name = "myNetworkSecurityGroup"
location = "eastus"
resource_group_name = "${azurerm_resource_group.myterraformgroup.name}"
security_rule {
name = "SSH"
priority = 1001
direction = "Inbound"
access = "Allow"
protocol = "Tcp"
source_port_range = "*"
destination_port_range = "22"
source_address_prefix = "*"
destination_address_prefix = "*"
}
}
在network_security_group_id下的module / main.tf文件中,我无法准确地放置$ {azurerm_network_security_group.apache-nsg.id}或$ {azurerm_network_security_group.nginx-nsg.id}。那我该放些什么以便可以在所有VM上重用此模块?
谢谢

您的问题对我来说还不是很清楚,但是我将假设您要创建一个通用网络安全组,该组要分配给VM模块的多个实例。
如果要传递来自main.tf at root
的安全组的ID,请执行以下操作:
在模块外部创建网络安全组资源,例如在main.tf at root
内,就像您在VM模块内部创建了一些(用于Apache和Nginx)一样,因此main.tf at root
看起来像这样:
resource "azurerm_network_security_group" "some_generic_vm_nsg" {
....
}
module "vm1" {
source = "/modules/vm/"
NSG = "${azurerm_network_security_group.some_generic_vm_nsg.id}"
}
请注意,我们现在将nsg的ID传递给您的VM模块实例。
但是,您的VM模块尚未声明NSG
变量。因此,创建文件modules/vm/variables.tf
并将其放入其中:
variable "NSG" {
type = "string"
}
在模块内部,network_security_group_id = { WHAT DO I PUT HERE? }
变为:
network_security_group_id = "${var.NSG}"
这样,您可以将同一网络安全组分配给多个VM模块实例。
您可以study this documentation以获取更多详细信息。
