一、操作场景
这篇说说如何在本地开启日志追踪，以获取更详细的日志，便于自查及协助工单处理。
二、操作步骤
1. 在 CLI 中执行 terraform apply 前，可以使用以下命令开启本地日志跟踪：
Linux/MacOS 系统：
export TF_LOG=DEBUGexport TF_LOG_PATH=./terraform.log
三、Running Environment
Operating System: Ubuntu 24.04.3 LTS / x86_64Runtime Version: GNU bash, version 5.2.21(1)-release (x86_64-pc-linux-gnu)
Windows 系统：
set TF_LOG=DEBUGset TF_LOG_PATH=.\\terraform.log
四、Running Environment
Operating System: Ubuntu 24.04.3 LTS / x86_64Runtime Version: GNU bash, version 5.2.21(1)-release (x86_64-pc-linux-gnu)
2. 开启后，再次执行以下命令。
terraform apply/destroy
执行完毕后，可查看 Terraform 本地文件夹会生成一个 terraform.log 文件。文件记录了 tencentcloud provider 定义的日志输出。如下：
五、示例
以下为执行出错示例，及分析定位问题的过程。本例中创建了一个 K8S cluster 并挂载一台已经存在的 CVM 作为节点。

CLI 提示错误如下：
[TencentCloudSDKError] Code=InternalError.CidrConflictWithOtherCluster, Message=DashboardError,Code : -10013 , Msg : CIDR_CONFLICT_WITH_OTHER_CLUSTER[cidr 10.1.0.0/16 is conflict with cluster id: cls-1zc0kpyo], err : CheckCIDRWithVPCClusters failed,CIDR(10.1.0.0/16) conflict with clusterCIDR,ClusterID:cls-1zc0kpyo,clusterCIDR:10.1.0.0/16,err:CIDR1:10.1.0.0/16,firstIP:10.1.0.0,conflict with CIDR2:10.1.0.0/16, RequestId=d7dfb178-f081-480a-9bc3-89efc5fb1db5
问题分析及定位：
1. 找到 requestId: d7dfb178-f081-480a-9bc3-89efc5fb1db5
2. 打开 terraform.log，搜索该 requestId，找到上下文如下所示：
2021-12-09T17:53:20.222+0800 [DEBUG] plugin.terraform-provider-tencentcloud.exe: 2021/02/25 17:53:20 [DEBUG] setting computed for "worker_instances_list" from ComputedKeys_CONFLICT_WITH_OTHER_CLUSTER[cidr 10.1.0.0/16 is conflict with cluster id: cls-1zc0kpyo], err : CheckCIDRWithVPCClusters failed,CIDR(10.1.0.0/16) conflict with clusterCIDR,ClusterID:cls-1zc0kpyo,clusterCIDR:10.1.0.0/16,err:CIDR1:10.1.0.0/16,firstIP:10.1.0.0,conflict with CIDR2:10.1.0.0/16"},"RequestId":"d7dfb178-f081-480a-9bc3-89efc5fb1db5"}},cost 370.8109ms6 is conflict with cluster id: cls-1zc0kpyo], err : CheckCIDRWithVPCClusters failed,CIDR(10.1.0.0/16) conflict with clusterCIDR,ClusterID:cls-1zc0kpyo,clusterCIDR:10.1.0.0/16,err:CIDR1:10.1.0.0/16,firstIP:10.1.0.0,conflict with CIDR2:10.1.0.0/16, RequestId=40d3ee5d-f723-4ef9-8f01-32d725464d512021-12-09T17:53:20.593+0800 [DEBUG] plugin.terraform-provider-tencentcloud.exe: 2021/12/09 17:53:20 common.go:79: [DEBUG] [ELAPSED] resource.tencentcloud_kubernetes_cluster.create elapsed 371 ms
3. 分析日志，可定位是创建 K8s cluster 过程中出现问题。示例中是因为 cidr 与已存在的其他 K8s cluster 有冲突造成的。
注意：说明：
注意：若 CLI 提示错误信息不够清晰，或无 requestID 报错造成定位有困难，可将 tf 项目文件，CLI 提示错误以及其产生的日志 terraform.log 文件通过 提交工单 请求协助。
