Terraform 配置Azure虚拟机DNS名称方案

核心原理

Azure 门户中虚拟机展示的DNS名称，绑定在虚拟机关联的公网IP资源上，并非直接配置在虚拟机资源本身，只需在公网IP的Terraform配置中添加对应参数即可实现需求。

配置示例

1. 公网IP资源配置（核心配置项）

resource "azurerm_public_ip" "vm_public_ip" {
  name                = "vm-pip-france"
  resource_group_name = azurerm_resource_group.your_rg.name
  location            = "francecentral"
  allocation_method   = "Dynamic" # 静态IP可改为Static

  # 此处填写你的服务器名称前缀，最终DNS会自动拼接区域后缀
  domain_name_label = "你的服务器名称"
}

2. 网卡关联公网IP（确保公网IP绑定到对应虚拟机）

resource "azurerm_network_interface" "vm_nic" {
  name                = "vm-nic-france"
  resource_group_name = azurerm_resource_group.your_rg.name
  location            = "francecentral"

  ip_configuration {
    name                          = "vm-ip-config"
    subnet_id                     = azurerm_subnet.your_subnet.id
    private_ip_address_allocation = "Dynamic"
    # 关联上述公网IP资源
    public_ip_address_id = azurerm_public_ip.vm_public_ip.id
  }
}

3. 虚拟机关联网卡

resource "azurerm_linux_virtual_machine" "your_vm" {
  name                = "你的服务器名称"
  resource_group_name = azurerm_resource_group.your_rg.name
  location            = "francecentral"
  size                = "Standard_D2s_v3"
  admin_username      = "adminuser"
  # 关联上述网卡资源
  network_interface_ids = [azurerm_network_interface.vm_nic.id]

  # 其他虚拟机配置（镜像、SSH密钥等）按需补充
}
