go - 为什么“terraform import”没有读取我的配置？

问题描述

我正在使用 Go 构建一个 Terraform 插件/提供程序。我的架构（链接）中有以下内容：

Importer: &schema.ResourceImporter{
  State: resourceKubernetesClusterNodePoolImport,
}

这是功能（链接）：

func resourceKubernetesClusterNodePoolImport(d *schema.ResourceData, m interface{}) ([]*schema.ResourceData, error) {
    apiClient := m.(*civogo.Client)

    clusterID, nodePoolID, err := utils.ResourceCommonParseID(d.Id())
    if err != nil {
        return nil, err
    }

    log.Printf("[INFO] retriving the node pool %s", nodePoolID)
    resp, err := apiClient.GetKubernetesCluster(clusterID)
    if err != nil {
        if resp != nil {
            return nil, err
        }
    }

    d.Set("cluster_id", resp.ID)
    for _, v := range resp.Pools {
        if v.ID == nodePoolID {
            d.Set("num_target_nodes", v.Count)
            d.Set("target_nodes_size", v.Size)
        }
    }

    return []*schema.ResourceData{d}, nil
}

当我在上面的函数顶部添加这些调试行时，结果 (reg和ok) 是空的并且false：

reg, ok := d.GetOk("region")
log.Printf("resourceKubernetesClusterNodePoolImport reg %+v\n", reg)
log.Println("resourceKubernetesClusterNodePoolImport ok", ok)
log.Println("resourceKubernetesClusterNodePoolImport d.Get()", d.Get("region"))
if !ok {
    return nil, fmt.Errorf("[ERR] Please provide a region in your import configuration")
}

痕迹：

问题是，在我运行上面的命令之前，我已经region在我的 Terraform 配置main.tf文件中添加了（并保存了它） 。tf import这是我的 main.tf 文件：

resource "civo_kubernetes_cluster" "my_cluster" {
    name = "my-cluster"
}

resource "civo_kubernetes_node_pool" "my_pool" {
    region = "LON1" <-- this line
}

为什么我的 Terraform 插件/提供程序将该区域视为空的？

据我了解，Terraform 在运行导入逻辑之前会先读取配置文件。我错了吗？我在这里错过了什么吗？

为了完整起见，我使用的是 Terraform v1.0.3，这是我的provider.tf文件...

terraform {
  required_providers {
    civo = {
      source  = "civo/civo"
      version = "99.0.0"
    }
  }
}

provider "civo" {
    token = “my-api-key-here”
}

...99.0.0我仅为测试而构建的版本在哪里。当我发布此问题时，此提供程序的最新/产品版本是0.10.9 。

解决方案

Importer.State函数无权访问现有配置，它提供了一个空的资源状态id-见代码。

作为一种解决方法，您可以允许region通过下划线（或任何与 id 或区域名称中的符号不​​冲突的符号）传递给 import 命令，如下所示：

terraform import civo_kubernetes_node_pool.my_pool <poolid>_<region>

并在你的进口商函数中处理这个：

func resourceKubernetesClusterNodePoolImport(d *schema.ResourceData, m interface{}) ([]*schema.ResourceData, error) {
    apiClient := m.(*civogo.Client)

    // extract id and region from provided string
    parts := strings.Split(d.Id(), "_")
    if len(parts) != 2 {
        return nil, errors.New("To import a pool, use the format {pool_id}_{region}")
    }

    poolId := parts[0]
    region := parts[1]

    // Set new ID for resource
    d.SetId(poolId)

    // Set region
    d.Set("region", region)

    // Do the rest of the import

    ...
}
