将计划块添加为条件 if 语句

Question

我正在使用 Terraform 从 Azure 市场部署 Linux 个虚拟机。

我在 linux 模块中设置了一个计划块，并在我的 main.tf 中声明了变量。

当运行 terraform plan/apply 它工作并构建 VM

我想知道如何修改我的模块和 main.tf 以将计划块添加为条件 if 语句。

我想使用此模块构建非 azure 市场和 azure 市场虚拟机。

我不希望单独的模块来执行此操作。

  resource_group_name = module.rg-ansiblecontroller.resource_group_name

Answer 1

你可以使用 dynamic blocks：

resource "azurerm_linux_virtual_machine" "vm-linux" {

  #....

  dynamic "plan" {
    for_each    =  var.plan_product == "rocky-lnx-8-latest" ? [1] : []
    content {
      name      = var.plan_name
      product   = var.plan_product
      publisher = var.plan_publisher
    }
 }
  
  # ... 
}

将计划块添加为条件 if 语句

Add the plan block as a conditional if statement
