Terraform 遍历值

Question

新手问题：有什么方法可以将变量循环存储在提到的代码中吗？。下面是我的配置变量。

config= [{  
"name" = shared_preload_libraries,
"values" = ["EXAMPLE1", "EXAMPLE2"]
},
{
"name" = "azure.extensions"
"values" = ["EXAMPLE1", "EXAMPLE2", "EXAMPLE3"]
}]

我需要以这样一种方式进行迭代，对于变量中的每个名称，相应的值应该在下面的代码中一一插入。

 resource "azurerm_postgresql_flexible_server_configuration" "example" {
  name      = name
  server_id = azurerm_postgresql_flexible_server.example.id
  value     = values 
}

Answer 1

您必须按如下方式展平您的config：

locals {
  flat_config = merge([
      for single_config in var.config: {
        for value in single_config.values: 
          "${single_config.name}-${value}" => {
              "name" = single_config.name
              "value" = value
          }
      }
    ]...) # do NOT remove the dots
}

然后

 resource "azurerm_postgresql_flexible_server_configuration" "example" {
  for_each  = local.flat_config
  name      = each.value.name
  server_id = azurerm_postgresql_flexible_server.example.id
  value     = each.value.value
}
