jenkins-gitlab-harbor-ceph基于Kubernetes的CI/CD运用（一）

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

免密钥拉取gitlab 代码

gitlab触发jenkins

gitlab生成token

复制此token，此token只显示一次：8YJobWVnZri-chf-QakJ

jenkins配置连接gitlab

系统管理 --> 系统设置 --> gitlab

创建jenkins任务

http://20.0.0.202:30006/project/gitlab-citest-pipeline 这个地址用来设置gitlab的webhook。

token: c8124514f0d3f60588a707470be57bca

gitlab设置webhooks

提交代码至gitlab触发jenkins任务

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；
1. 声明式：遵循与Groovy相同语法。pipeline
2. 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: '请选择要发布的项目git地址', name: 'git'
  choice choices: ['20.0.0.204', '20.0.0.205', '20.0.0.206'], description: '请选择要发布的服务器', name: 'host'
            
        }
    stages {
        stage('Build') {
            steps {
                echo "${git}"
            }
        }
        stage('Test') {
            steps {
                echo 'Testing'
            }
        }
        stage('Deploy') {
            steps {
                echo "${host}"
            }
        }
    }
}
