1. Install the plug-in

The first step of continuous deployment needs to check whether the gitlab plug-in is installed: gitlab hookplug-in and gitlabplug-in (I am jenkins version 2.397, it seems that only this plug-in is installed)

2. Build tasks

Create a new gitlab task

3. Configure triggers for tasks

Set the token, there is such a regular configuration on the Internet, I did not use it, I directly use the second by name main

Allowed branches ：

Allow all branches to trigger this job #允许所有分支触发此作业


Filter branches by name #按名称过滤分支
Include ：dev #允许触发构建的分支，dev 分支提交会自动构建
Exclude：master #排除触发构建的分支，此时 master 分支提交不会自动构建

Filter branches by regex #通过正则表达式过滤分支
Source Branch Regex： #源分支正则表达式
Target Branch Regex：.*dev #目标分支正则表达式，允许触发构建的 dev 分支

Filter merge request by label #按标签过滤合并请求
Include： #允许触发构建的标签
Exclude： #排除触发自动构建的标签

4. Go to gitlab to set up webhooks

4.1 Setting up the network

This step on the pit, if your gitlab is 10.6+ version first operate this, if the lower version, skip here

报错：Url is blocked: Requests to the local network are not allowed

reason:
Gitlab version 10.6 and later, for security reasons, do not allow sending webhook requests to the local network by default

Solution:
