目录

一、实验

1.Jenkins远程下载GiaLab仓库代码

2.curl远程触发Jenkins流水线

[3.GitLab Webhook触发Jenkins流水线](#3.GitLab Webhook触发Jenkins流水线)

二、问题

1.GitLab配置Webhook时报错

一、实验

1.Jenkins远程下载GiaLab仓库代码

(1) Jenkins添加选项参数

(2)添加字符参数

(3)查看构建参数情况

(4)添加凭证

(5)生成流水线脚本

(6)生成

bash 复制代码 
checkout scmGit(branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: '89c7573f-2d38-4aba-af7c-d8e62582b4d7', url: 'http://192.168.204.8:82/devops03/devops03-demo-service.git']])

(7)保存流水线

(8)开始构建feature-01

(9)成功

(10)先查看仓库

(11)再查看分支

(12)gitlab查看特性分支的2个文件

(13) jenkins日志显示有2个文件

(14)开始构建master

(15)成功

(16)修改回放

(17)成功

2.curl远程触发Jenkins流水线

(1)Jenkins 开启 Webhook Trigger

(2)开启打印日志

(3)添加token，以作业名命名

(4)curl远程触发

bash 复制代码 
curl "http://192.168.204.15:8080/generic-webhook-trigger/invoke?token=devops03-demo-service"

(5)成功

(6)查看日志

3.GitLab Webhook触发Jenkins流水线

(1)GitLab添加Webhooks的URL

(2)提交特性分支

(3)push

(4)HTTP200 触发成功

(5)jenkins成功触发流水线

(6)查看日志

(7)提交特性分支

(8)选择edit查看（提交代码触发hook）

(9)post请求（发送给jenkins分析）

bash 复制代码 
Request URL: POST http://192.168.204.15:8080/generic-webhook-trigger/invoke?token=devops03-demo-service 200

(27)构建成功

(28) 收到邮件

二、问题

1.GitLab配置Webhook时报错

（1）报错

（2）原因分析

未配置允许外部请求

（3）解决方法

bash 复制代码 
进入 Admin area => Settings => Network ，然后点击 Outbound requests 右边 的"expand"按钮，按图片勾选，并点击 Save changes按钮

再重新配置Webhook即可正确生成Hook
