azure - 使用 AzureRM 提供程序从 terraform_remote_state 读取

Question

我正在尝试在一个模块中部署 VNET，并将远程状态的子网 ID 存储在 Azure Blob 存储中。

我发现我的输出似乎已正确存储在远程状态 blob 中。

当我尝试读取另一个模块中的子网 ID 时出现问题

terraform {
  backend "azurerm" {
    storage_account_name  = "mystorage"
    container_name        = "tfstate"
    key                   = "terraform.tfstate"

  }
}

resource "azurerm_subnet" "defaultsubnet" {
  name  = "default"
  address_prefix = "10.10.1.0/24"
  resource_group_name = "my-rg"
  virtual_network_name = "my-vnet"
}

output "id" {
  value = "${azurerm_subnet.defaultsubnet.id}"
}

"outputs": {
                "id": {
                    "sensitive": false,
                    "type": "string",
                    "value": "/subscriptions/***/resourceGroups/my-rg/providers/Microsoft.Network/virtualNetworks/my-vnet/subnets/default"
                },

data "terraform_remote_state" "sub" {
  backend = "azurerm"
  config = {
    storage_account_name = "mystorage"
    container_name       = "tfstate"
    key                  = "terraform.tfstate"

  }
}

resource "azurerm_kubernetes_cluster" "aks" {
.....
    agent_pool_profile {
        vnet_subnet_id = "${data.terraform_remote_state.sub.id}"
    }
}

vnet_subnet_id = "${data.terraform_remote_state.sub.id}"

此行失败并显示以下消息:

Error running plan: 1 error(s) occurred:\n\n* azurerm_kubernetes_cluster.aks: Can not parse \"agent_pool_profile.0.vnet_subnet_id\" as a resource id: Cannot parse Azure ID: parse 2019-04-09 15:21:55.916021 +0000 UTC: invalid URI for request\n\n\n"}

它以某种方式将子网 ID 转换为日期。甚至认为我在这里发现了类似的问题https://github.com/hashicorp/terraform/issues/20147我仍然无法将该解决方法应用于我的案例。

如果可能，您应该避免使用远程状态数据源并使用不利于您的提供商的 native 数据源。

在这种情况下，您应该使用 azurerm_subnet data source相反:

data "azurerm_subnet" "subnet" {
  name                 = "default"
  virtual_network_name = "my-vnet"
  resource_group_name  = "my-rg"
}

resource "azurerm_kubernetes_cluster" "aks" {
  #...
  agent_pool_profile {
    vnet_subnet_id = "${data.azurerm_subnet.subnet.id}"
  }
}
