Как эффективно использовать azure_virtual_machine_extension в Azure Terraform

Как эффективно использовать azure_virtual_machine_extension в Azure Terraform

Вот код Terraform для создания нескольких виртуальных машин и нескольких cmd с VM extensions для выполнения Bash code внутри VMs.

переменные.tf

variable "vms" {
  default = [
    {
      name   = "vm1"
      size   = "Standard_DS1_v2"
      admin_username = "Venkat"
      admin_password = "Welcome@123$"
      computer_name   = "Linux_VM1"
      new_computername = "Venkat_LinuxVM1"
    },
    {
      name   = "vm2"
      size   = "Standard_DS1_v2"
      admin_username = "Venkat"
      admin_password = "Welcome@123$"
      computer_name   = "Linux_VM2"
      new_computername = "Venkat_LinuxVM2"
    }
  ]

Терраформ применить

После выполнения VM Extension имя хоста было успешно изменено.

Имя хоста ВМ 1:

Обновлять:

Чтобы запустить несколько команд с помощью azurerm_virtual_machine_extension, создайте файл bash и загрузите тот же файл в учетную запись хранения. Затем используйте каплю URL в fileUris в terraform.

   resource "azurerm_virtual_machine_extension" "hostname" {
  count               = length(var.vms)
  name                = "hostname"
  virtual_machine_id  = azurerm_linux_virtual_machine.example[count.index].id
  publisher           = "Microsoft.Azure.Extensions"
  type                = "CustomScript"
  type_handler_version = "2.0"
  
      settings = <<SETTINGS
        fileUris = [
          "https://samplestoragevm.blob.core.windows.net/vmstorage/script.sh",
        ]
        commandToExecute = "sh script.sh"
}
