Terraform Azure将虚拟机调配到现有子网/vnet/resourcegroup

Question

我有一个现有的Azure环境，其中已经创建了资源组、网络、vnet和子网。我想使用terraform自动将VM部署到这个现有的Azure环境中，但所有的示例和文档都是面向从头开始构建整个新环境/基础设施的。

关于如何使用terraform将VM部署到现有的Azure环境，有没有人能建议一些文档或示例？

您可以使用Data Source: azurerm_subnet和azurerm_resource_group访问现有子网和资源组的属性。

使用现有子网创建新Linux虚拟机的示例。在网络接口subnet_id = "${data.azurerm_subnet.test.id}"中引用子网数据源的输出subnet_id

# refer to a resource group
data "azurerm_resource_group" "test" {
  name = "nancyResourceGroup"
}

#refer to a subnet
data "azurerm_subnet" "test" {
  name                 = "mySubnet"
  virtual_network_name = "myVnet"
  resource_group_name  = "nancyResourceGroup"
}

# Create public IPs
resource "azurerm_public_ip" "test" {
    name                         = "myPublicIP-test"
    location                     = "${data.azurerm_resource_group.test.location}"
    resource_group_name          = "${data.azurerm_resource_group.test.name}"
    public_ip_address_allocation = "dynamic"

}

# create a network interface
resource "azurerm_network_interface" "test" {
  name                = "nic-test"
  location            = "${data.azurerm_resource_group.test.location}"
  resource_group_name = "${data.azurerm_resource_group.test.name}"

  ip_configuration {
    name                          = "testconfiguration1"
    subnet_id                     = "${data.azurerm_subnet.test.id}"
    private_ip_address_allocation = "dynamic"
    public_ip_address_id          = "${azurerm_public_ip.test.id}"
  }
}

# Create virtual machine
resource "azurerm_virtual_machine" "test" {
    name                  = "myVM-test"
    location              = "${azurerm_network_interface.test.location}"
    resource_group_name   = "${data.azurerm_resource_group.test.name}"
    network_interface_ids = ["${azurerm_network_interface.test.id}"]
    vm_size               = "Standard_DS1_v2"

# Uncomment this line to delete the OS disk automatically when deleting the VM
delete_os_disk_on_termination = true

# Uncomment this line to delete the data disks automatically when deleting the VM
delete_data_disks_on_termination = true

  storage_image_reference {
    publisher = "Canonical"
    offer     = "UbuntuServer"
    sku       = "16.04-LTS"
    version   = "latest"
  }
   storage_os_disk {
    name              = "myosdisk1"
    caching           = "ReadWrite"
    create_option     = "FromImage"
    managed_disk_type = "Standard_LRS"
  }
   os_profile {
    computer_name  = "hostname"
    admin_username = "testadmin"
    admin_password = "Password1234!"
  }
   os_profile_linux_config {
    disable_password_authentication = false
  }

}
