azure - 如果我不想为 terraform 中的所有对象 map 提供值

Question

• 如果我不想为虚拟中的所有子网提供路由表网络那么我应该在这里使用什么，因为如果我没有路线运行表然后我收到错误。在subnet2 中需要路由表id。

│ Missing required argument
│
│ with module.virtual_network["test-vnet"].azurerm_subnet_route_table_association.route-link-subnet["subnet2"],
│ on modules\virtualNetwork\main.tf line 30, in resource "azurerm_subnet_route_table_association" "route-link-subnet":
│ 30: route_table_id = each.value.route_table
│
│ The argument "route_table_id" is required, but no definition was found. 

我在这里创建多个虚拟网络，每个虚拟网上有多个子网。

variable "networks" {
      type = map(object({
        resource_group_name = string
        location            = string
        addressSpace        = list(string)
        dnsServers          = optional(list(string))
        subnets = map(object({

          privateLinkServiceNetworkPolicies = optional(bool)
          service_endpoints                 = optional(list(string))
          route_table                       = optional(string)
        }))
      }))
    }

          }
        }
      }
    }
  }

resource "azurerm_subnet_route_table_association" "route-link-subnet" {
  for_each       = var.subnets
  subnet_id      = module.subnets[each.key].subnet_id
  route_table_id = each.value.route_table
  depends_on = [
    module.subnets,
    azurerm_virtual_network.Virtual_Network
  ]
}

Answer 1

您必须在 var.subnets 中为 subnet2 提供 route_table。
