Aplicativo de função do Azure com várias cadeias de conexão via Terraform

  • 772

Estou tentando adicionar várias strings de conexão nas configurações de um aplicativo de função do Azure por meio do Terraform, mas estou recebendo um erro

resource "azurerm_linux_function_app" "ali_test_fa" {
name                       = local.function_app_function_app_name
resource_group_name        = data.azurerm_resource_group.sandbox_resource_group.name
location                   = 
data.azurerm_resource_group.sandbox_resource_group.location
service_plan_id            = azurerm_service_plan.ali_test_asp.id
storage_account_name       = azurerm_storage_account.ali_test_fa_st.name
storage_account_access_key = azurerm_storage_account.ali_test_fa_st.primary_access_key
tags                       = local.tags
dynamic "connection_string" {
for_each = toset(local.connection_strings)
content {
  name  = each.value.name
  type  = each.value.type
  value = each.value.value
}

}

Especifiquei as strings de conexão como a seguir:

local = {
connection_strings = [
    {
      value = "I am a sensitive sql database connection string"
      type  = "SQLServer"
      name  = "connection_string_sql_database"
    }
  ]
}

Tentei o seguinte, mas não obtive sucesso:

for_each = local.connection_strings
or
for_each = { for inst in local.connection_strings : inst.name => inst }

Atualização 1 : Parece que o seguinte funcionou

dynamic "connection_string" {
for_each = local.connection_strings
content {
  name  = connection_string.value.name
  type  = connection_string.value.type
  value = connection_string.value.value
}

}

    Uma referência a "each.value" foi usada em um contexto no qual ele não estava disponível, como quando a configuração não contém mais o valor em sua expressão "for_each".

    O erro each.value cannot be used in this contextsignifica que não há nada each.valuepara fazer referência aqui com o dynamic "connection_string"bloco, pois você está definindo a entrada como uma lista de mapas.

    Modifique o dynamicbloco conforme mostrado abaixo se você estiver passando valores por definição no localsbloco.

    dynamic "connection_string" {
for_each = local.connection_strings
content {
  name  = connection_string.value.name
  type  = connection_string.value.type
  value = connection_string.value.value
}

    main.tf:

    locals {
  connection_strings = [
    {
      value = "I am a sensitive sql database connection string"
      type  = "SQLServer"
      name  = "connection_string_sql_database"
    }
  ]
}

provider "azurerm" {
  features {}
  subscription_id = "xxxx"
}

resource "azurerm_resource_group" "example" {
  name     = "funcresg"
  location = "West Europe"
}

resource "azurerm_storage_account" "example" {
  name                     = "jafunctionappsa"
  resource_group_name      = azurerm_resource_group.example.name
  location                 = azurerm_resource_group.example.location
  account_tier             = "Standard"
  account_replication_type = "LRS"
}

resource "azurerm_service_plan" "example" {
  name                = "jahnewplan"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location
  os_type             = "Linux"
  sku_name            = "B1"
}

resource "azurerm_linux_function_app" "example" {
  name                = "jahexamplesampp"
  resource_group_name = azurerm_resource_group.example.name
  location            = azurerm_resource_group.example.location

  storage_account_name       = azurerm_storage_account.example.name
  storage_account_access_key = azurerm_storage_account.example.primary_access_key
  service_plan_id            = azurerm_service_plan.example.id

dynamic "connection_string" {
for_each = local.connection_strings
content {
  name  = connection_string.value.name
  type  = connection_string.value.type
  value = connection_string.value.value
}
}
site_config{}
}

    Alternativamente , você pode usarvariableblock em vezlocalsde pegar a entrada como list(object) como mostrado abaixo.

    variable "connection_strings" {
  type = list(object({
    value  = string
    type  = string
    name = string
  }))
  default = [{
      value = "I am a sensitive sql database connection string"
      type  = "SQLServer"
      name  = "connection_string_sql_database"
    }] 
}

    dynamicbloquear em main.tf:

    dynamic "connection_string" {
    for_each = var.connection_strings
    content {
      name = each.value.name
      type = each.value.type
      value = each.value.value
    }
  }
