开启日志追踪

最后更新时间:2023-05-29 15:17:03

    操作场景

    本文介绍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。
    

    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:
    
    export TF_LOG=DEBUG
    export TF_LOG_PATH=./terraform.log
    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 的文件。文件记录了 tencentcloud provider 定义的日志输出。如下图所示:
    
    
    

    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 作节点。
    ➜ terraform apply
    
    2021/12/09 17:53:02 [WARN] Log levels other than TRACE are currently unreliable, and are supported only for backward compatibility.
    Use TF_LOG=TRACE to see Terraform's internal logs.

    Do you want to perform these actions?
    Terraform will perform the actions described above.
    Only 'yes' will be accepted to approve.
    
    Enter a value: yes

    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:

    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。
    说明:
    若 CLI 提示错误信息不够清晰,或无 requestID 的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。
