terrain脚本中未触发custom_data参数

Question

我正在使用terraform在azure中创建虚拟机，在该虚拟机中，我传递了自定义数据参数，该参数实际上应该触发执行少量安装的yaml文件。但这并没有被触发。您能否就此问题提供建议。enter code here

控制器虚拟机

resource "azurerm_virtual_machine" "controller-vm" {
name                  = "controller-vm"`enter code here`
location              = var.region

resource_group_name   = azurerm_resource_group.resourcegroup.name
network_interface_ids = [azurerm_network_interface.controllernic.id]
vm_size               = var.ctr_instance_type

storage_os_disk {
    name              = "controller-os-disk"
    caching           = "ReadWrite"
    create_option     = "FromImage"
    disk_size_gb      = "400"
    managed_disk_type = "Standard_LRS"
}

storage_data_disk {
    name              = "controller-data-disk0"
    caching           = "ReadWrite"
    create_option     = "Empty"
    managed_disk_type = "Standard_LRS"
    disk_size_gb      = "512"
    lun               = 1
}

storage_data_disk {
    name              = "controller-data-disk1"
    caching           = "ReadWrite"
    create_option     = "Empty"
    managed_disk_type = "Standard_LRS"
    disk_size_gb      = "512"
    lun               = 2
}

storage_image_reference {
    publisher = "OpenLogic"
    offer     = "CentOS-CI"
    sku       = "7-CI"
    version   = "latest"
}

os_profile {
    computer_name  = "controller.${var.project_id}.local"
    admin_username = var.user
    custom_data = file(pathexpand(var.ctr_cloud_init_file))
}

os_profile_linux_config {
    disable_password_authentication = true
    ssh_keys {
        path     = "/home/${var.user}/.ssh/authorized_keys"
        key_data = file(pathexpand(var.ssh_pub_key_path))
    }
}

boot_diagnostics {
    enabled     = "true"
    storage_uri = azurerm_storage_account.storageaccount.primary_blob_endpoint
}

tags = {
    environment = var.project_id,
    user = var.user
}

}

上面的代码中有一个custom_data = file（pathexpand（var.ctr_cloud_init_file）），该文件应实际调用yaml文件。这里没有发生。

请找到我正在使用的yaml文件。 ctr_cloud_init_file

users:
- name: bluedata
  groups: [sudo, wheel]
  shell: /bin/bash
  sudo: ['ALL=(ALL) NOPASSWD:ALL']
  ssh-authorized-keys:

要为Azure VM提供Cloud-init文件，这不是直接加载文件的好方法。对于Cloud-init，我建议您使用template_cloudinit_config，这是Cloud-init的特殊提供程序，其功能集专用于cloud-init的功能。这是示例代码：

template_cloudinit_config
