使用Terraform在Azure中为每个可用性区域创建子网

Question

我正在尝试使用terraform在Azure中为每个可用区域创建子网。我正在使用以下代码创建子网。

resource "azurerm_subnet" "public_subnet" {
  name                 = "public_subnet"
  virtual_network_name = azurerm_virtual_network.vnet.name
  resource_group_name  = azurerm_resource_group.terraform_rg.name
  address_prefix       = "10.20.10.0/24"
}

[我的要求在AWS中是可能的。因为我是AZure的新手，所以我不确定是否可以在Azure中做同样的事情。如果有人伸出援手来帮助我，那将很好。

预先感谢！

[Azure子网不是Zonal service（资源固定到特定区域的地方），请参考Azure services and regions that support Availability Zones。因此，您需要为每个可用性区域创建特定的支持服务。

例如，您可以在每个可用性区域中创建一个Azure VM或Azure公共IP。

resource "azurerm_resource_group" "example" {
  name     = "example-resources"
  location = "east us"
}

resource "azurerm_public_ip" "example" {
  name                = "acceptanceTestPublicIp1"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location
  allocation_method   = "Static"
  sku = "Standard"
  zones = ["1"]

}

resource "azurerm_virtual_network" "example" {
  name                = "example-network"
  address_space       = ["10.0.0.0/16"]
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
}

resource "azurerm_subnet" "example" {
  name                 = "internal"
  resource_group_name  = azurerm_resource_group.example.name
  virtual_network_name = azurerm_virtual_network.example.name
  address_prefix       = "10.0.2.0/24"
}

resource "azurerm_network_interface" "example" {
  name                = "example-nic"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name

  ip_configuration {
    name                          = "internal"
    subnet_id                     = azurerm_subnet.example.id
    private_ip_address_allocation = "Dynamic"
    public_ip_address_id          = azurerm_public_ip.example.id
  }
}

resource "azurerm_linux_virtual_machine" "example" {
  name                = "example-machine"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location
  size                = "Standard_F2"
  zone = "1"
  admin_username      = "adminuser"
  network_interface_ids = [
    azurerm_network_interface.example.id,
  ]

 admin_ssh_key {
    username   = "adminuser"
    public_key = file("~/.ssh/id_rsa.pub")
  }

  os_disk {
    caching              = "ReadWrite"
    storage_account_type = "Standard_LRS"
  }

  source_image_reference {
    publisher = "Canonical"
    offer     = "UbuntuServer"
    sku       = "16.04-LTS"
    version   = "latest"
  }
}
