HI Guys and happy new year to all

I got an issue to gatter the token generate by the bloc ressource below which have an iteration with an for_each loop.

my varibale map is :

 variable "wvd_hostpool" {
 description = "Please provide the required information to create a WVD hostpool."
 type        = map(any)
 default = {
   hp-azcan-weu-wvd-01 = {
     "name"                             = "hp-azcan-weu-wvd-01"
     "type"                             = "Personal"
     "load_balancer_type"               = "DepthFirst"
     "personal_desktop_assignment_type" = "Automatic"
     "maximum_sessions_allowed"         = 16
     "expiration_date"                  = "2022-02-10T18:46:43Z"
     "friendly_name"                    = "Canary"
     "description"                      = "Dedicated to canary deployments."
     "location"                         = "westeurope"
     "vm_count"                         = 1
     "vm_size"                          = "Standard_F4s_v2"
     "vm_prefix"                        = "AZWEUHP01TST"
     "validate_environment"             = "true"
   },
   hp-azprd-weu-wvd-01 = {
     "name"                             = "hp-azprd-weu-wvd-01"
     "type"                             = "Pooled"
     "load_balancer_type"               = "DepthFirst"
     "personal_desktop_assignment_type" = "Automatic"
     "maximum_sessions_allowed"         = 16
     "expiration_date"                  = "2022-02-10T18:46:43Z"
     "friendly_name"                    = "desktop"
     "description"                      = "Dedicated to medium workload type (Microsoft Word, CLIs, ...)."
     "location"                         = "westeurope"
     "vm_count"                         = 1
     "vm_size"                          = "Standard_F4s_v2"
     "vm_prefix"                        = "AZWEUHP01WKT"
     "validate_environment"             = "false"
   },

the ressource bloc :

  resource "azurerm_virtual_desktop_host_pool" "wvd_hostpool" {
  for_each                         = var.wvd_hostpool
  name                             = each.value.name
  location                         = each.value.location
  custom_rdp_properties            = "audiocapturemode:i:1;audiomode:i:0;"
  resource_group_name              = data.azurerm_resource_group.avd_rg.name
  validate_environment             = each.value.validate_environment
  type                             = each.value.type
  load_balancer_type               = each.value.load_balancer_type
  friendly_name                    = each.value.friendly_name
  description                      = each.value.description
  personal_desktop_assignment_type = each.value.personal_desktop_assignment_type
  maximum_sessions_allowed         = each.value.maximum_sessions_allowed

  registration_info {
    expiration_date = each.value.expiration_date
  }
}

I would get the value of the token generate under registration_info to save it to a key vault for reuse or export it to an output but has you can see I getting an error with invalid index. I speding 2 day without sucess at this could you help me please ?

  resource "azurerm_key_vault_secret" "wvd_registration_info" {
  for_each     = var.wvd_hostpool
  name         = each.value.name
  value        = azurerm_virtual_desktop_host_pool.wvd_hostpool[each.value.name].registration_info[0].token
  key_vault_id = azurerm_key_vault.wvd_key_vault.id
  depends_on   = [azurerm_role_assignment.wvd_sp]
}

the same result

on my terraform plan it seem ok but when to apply I getting the same error

azurerm_virtual_desktop_host_pool.wvd_hostpool["hp-azprd-weu-wvd-02"] must be replaced

-/+ resource "azurerm_virtual_desktop_host_pool" "wvd_hostpool" {

        name                             = "hp-azprd-weu-wvd-02"

          - "prj" = "pop304"

        } -> null

      + registration_info {

          + expiration_date = "2022-02-10T18:46:43Z"

          + reset_token     = (known after apply)

          + token           = (sensitive value)

        }

    }

could some of you can help me please

As both for_each use the same variable, you could refer to each.key in this case.

value= lookup(azurerm_virtual_desktop_host_pool.wvd_hostpool[each.key].registration_info,token,"none“}
