Question

我正在尝试使用element创建一个azure lb规则，这是错误消息和下面列出的代码。

我应该在main.tf文件或variables.tf文件中进行哪些更改以使元素正常工作。但是，当我直接提供端口（已注释）时，代码将执行而没有任何问题。

发生1个错误：



azurerm_lb_rule.test：发生1个错误：



azurerm_lb_rule.test：在第3列第1行：元素：参数1应该为类型列表，类型字符串为：



$ {element（var.lb_port [“ $ {element（keys（var.lb_port），count.index）}”]]，   2）}

main.tf

resource "azurerm_lb_rule" "test" {
  resource_group_name            = "${azurerm_resource_group.test.name}"
  loadbalancer_id                = "${azurerm_lb.lb.id}"
  name                           = "LBRule"
  protocol                       = "Tcp"
  #frontend_port                  = 3389
  #backend_port                   = 3389
 protocol                       = "${element(var.lb_port["${element(keys(var.lb_port), count.index)}"], 0)}"
 frontend_port                  = "${element(var.lb_port["${element(keys(var.lb_port), count.index)}"], 1)}"
 backend_port                   = "${element(var.lb_port["${element(keys(var.lb_port), count.index)}"], 2)}"
  frontend_ip_configuration_name = "${var.frontend_name}"
}

variables.tf

variable "lb_port" {
  description = "Protocols to be used for lb health probes and rules."
  default     = {"var1" = "tcp,3389,3389"}
}

根据您的要求，可以将变量lb_port定义为地图类型，然后使用lookup函数从给定键的地图中检索单个元素的值。

例如，

variable "lb_port" {
  description = "Protocols to be used for lb health probes and rules."
   default = {
    "protocol" = "TCP"
    "frontend_port" = "3389"
    "backend_port" = "3389"
  }
}
...

resource "azurerm_lb_rule" "test" {
  resource_group_name            = "${azurerm_resource_group.test.name}"
  loadbalancer_id                = "${azurerm_lb.lb.id}"
  name                = "LBRule"
  #protocol            = "Tcp"
  #frontend_port                  = 3389
  #backend_port                   = 3389
  protocol                       = "${lookup(var.lb_port, "protocol" )}"
  frontend_port                  = "${lookup(var.lb_port, "frontend_port" )}"
  backend_port                   = "${lookup(var.lb_port, "backend_port" )}"
  frontend_ip_configuration_name = "${var.frontend_name}"
  ...
}
