我想从 terraform 上的资源更新变量。

那可能吗？我对这项技术有点陌生。

variable "contador" {
    default = 0
}

resource "azurerm_managed_disk" "test-disks-test3" {
    count                   = "${length(var.disks_size) * var.vm_number}"
    name                    = "SRV${var.service_base_name}${var.service_environment}01-DATADISK-0${count.index}"
    location                = "westeurope"
    resource_group_name     = "${azurerm_resource_group.test-rg-test3.name}"
    storage_account_type    = "${var.disk_tier}_${var.disk_replication}"  
    create_option           = "Empty"
    disk_size_gb            = "${element(var.disks_size, count.index)}"

    var.contador            = "${count.index % length(var.disks_size) == (length(var.disks_size) - 1) ? (var.contador + 1)  : var.contador}"

    tags{
        environment = "TestWork"
    }
}

有问题的行是：

var.contador = "${count.index % length(var.disks_size) == (length(var.disks_size) - 1) ? (var.contador + 1)  : var.contador}"
