注：这部分的学习还是要靠自己多点点 多尝试尝试
这部分19年3月份我是玩的很溜的，一年没用，基本忘光光了。
学习要温故而知新！

gitlab创建项目
创建组：**
使用管理员root创建组，一个组里面可以有多个项目分支，可以将开发添加到组里面进行设置权限，不同的组就是公司不同的开发项目或者服务模块，不同的组添加不同的开发即可实现对开发设置权限的管理。
使用管理员创建项目

Jenkins Pipeline 及参数化构建
**Jenkins参数化构建流程图 ** 【网图】
Jenkins Pipeline是一套插件，支持在Jenkins中实现集成和持续交付管道；
- Pipeline通过特定语法对简单到复杂的传输管道进行建模；
- 声明式：遵循与Groovy相同语法。pipeline { }
- 脚本式：支持Groovy大部分功能，也是非常表达和灵活的工具。node { }
- Jenkins Pipeline的定义被写入一个文本文件，称为Jenkinsfile。
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'Building'
}
}
stage('Test') {
steps {
echo 'Testing'
}
}
stage('Deploy') {
steps {
echo 'Deploying'
}
}
}
}
pipeline简单使用
pipeline {
agent any
parameters {
choice choices: ['20.0.0.208/web-test/app1.git', '20.0.0.208/web-test/app2.git', '20.0.0.208/web-test/app3.git'], description: '请选择要的项目git地址', name: 'git'
choice choices: ['20.0.0.204', '20.0.0.205', '20.0.0.206'], description: '请选择要的服务器', name: 'host'
}
stages {
stage('Build') {
steps {
echo "${git}"
}
}
stage('Test') {
steps {
echo 'Testing'
}
}
stage('Deploy') {
steps {
echo "${host}"
}
}
}
}
