🚀 Jenkins与其他DevOps工具链集成

1.1 Jenkins + GitLab：代码到部署的完美闭环

还在为代码提交后的自动化流程发愁？Jenkins和GitLab的组合就像是天作之合！

yaml:gitlab-ci.yml 复制代码

stages:
  - build
  - test
  - deploy

variables:
  JENKINS_URL: "http://jenkins.company.com"
  JENKINS_JOB: "my-awesome-project"

trigger_jenkins:
  stage: deploy
  script:
    - |
      curl -X POST "$JENKINS_URL/job/$JENKINS_JOB/buildWithParameters" \
        --user "$JENKINS_USER:$JENKINS_TOKEN" \
        --data "GIT_COMMIT=$CI_COMMIT_SHA&BRANCH_NAME=$CI_COMMIT_REF_NAME"
  only:
    - master
    - develop

Jenkins Pipeline配置：

groovy:Jenkinsfile 复制代码

pipeline {
    agent any
    
    parameters {
        string(name: 'GIT_COMMIT', defaultValue: '', description: 'Git commit hash')
        string(name: 'BRANCH_NAME', defaultValue: 'master', description: 'Branch name')
    }
    
    stages {
        stage('Checkout') {
            steps {
                script {
                    if (params.GIT_COMMIT) {
                        checkout([
                            $class: 'GitSCM',
                            branches: [[name: params.GIT_COMMIT]],
                            userRemoteConfigs: [[url: 'https://gitlab.company.com/project.git']]
                        ])
                    } else {
                        checkout scm
                    }
                }
            }
        }
        
        stage('Build & Test') {
            parallel {
                stage('Unit Tests') {
                    steps {
                        sh 'mvn test'
                        publishTestResults testResultsPattern: 'target/surefire-reports/*.xml'
                    }
                }
                
                stage('Code Quality') {
                    steps {
                        withSonarQubeEnv('SonarQube') {
                            sh 'mvn sonar:sonar'
                        }
                    }
                }
            }
        }
        
        stage('Deploy') {
            when {
                anyOf {
                    branch 'master'
                    branch 'develop'
                }
            }
            steps {
                script {
                    def environment = params.BRANCH_NAME == 'master' ? 'production' : 'staging'
                    sh "ansible-playbook -i inventory/${environment} deploy.yml"
                }
            }
        }
    }
    
    post {
        always {
            // 发送通知到Slack
            slackSend(
                channel: '#devops',
                color: currentBuild.result == 'SUCCESS' ? 'good' : 'danger',
                message: "Build ${currentBuild.result}: ${env.JOB_NAME} - ${env.BUILD_NUMBER}"
            )
        }
    }
}

1.2 Jenkins + Ansible：自动化部署的黄金搭档

想要实现真正的"一键部署"？Jenkins + Ansible绝对是你的不二选择！

yaml:ansible-playbook.yml 复制代码

---
- name: Deploy Application
  hosts: "{{ target_environment }}"
  become: yes
  vars:
    app_name: "my-awesome-app"
    app_version: "{{ build_number }}"
    
  tasks:
    - name: Stop existing service
      systemd:
        name: "{{ app_name }}"
        state: stopped
      ignore_errors: yes
      
    - name: Download artifact from Jenkins
      get_url:
        url: "{{ jenkins_url }}/job/{{ job_name }}/{{ build_number }}/artifact/target/{{ app_name }}-{{ app_version }}.jar"
        dest: "/opt/{{ app_name }}/{{ app_name }}.jar"
        mode: '0755'
        
    - name: Update configuration
      template:
        src: application.yml.j2
        dest: "/opt/{{ app_name }}/application.yml"
        
    - name: Start service
      systemd:
        name: "{{ app_name }}"
        state: started
        enabled: yes
        
    - name: Health check
      uri:
        url: "http://localhost:8080/actuator/health"
        method: GET
        status_code: 200
      retries: 5
      delay: 10

Jenkins中的Ansible集成：

groovy:jenkins-ansible-pipeline 复制代码

stage('Deploy with Ansible') {
    steps {
        script {
            def inventoryFile = params.ENVIRONMENT == 'production' ? 'prod' : 'staging'
            
            ansiblePlaybook(
                playbook: 'deploy.yml',
                inventory: "inventory/${inventoryFile}",
                extraVars: [
                    target_environment: params.ENVIRONMENT,
                    build_number: env.BUILD_NUMBER,
                    jenkins_url: env.JENKINS_URL,
                    job_name: env.JOB_NAME
                ],
                credentialsId: 'ansible-ssh-key'
            )
        }
    }
}

1.3 Jenkins + Prometheus + Grafana：监控体系的完美三角

部署完了就万事大吉？NoNo，监控才是王道！

yaml:prometheus-config.yml 复制代码

global:
  scrape_interval: 15s
  
scrape_configs:
  - job_name: 'jenkins'
    static_configs:
      - targets: ['jenkins:8080']
    metrics_path: '/prometheus'
    
  - job_name: 'application'
    static_configs:
      - targets: ['app:8080']
    metrics_path: '/actuator/prometheus'

Jenkins Pipeline中的监控集成：

groovy:monitoring-pipeline 复制代码

stage('Setup Monitoring') {
    steps {
        script {
            // 创建Grafana Dashboard
            sh '''
                curl -X POST "http://grafana:3000/api/dashboards/db" \
                  -H "Content-Type: application/json" \
                  -H "Authorization: Bearer ${GRAFANA_API_KEY}" \
                  -d @grafana-dashboard.json
            '''
            
            // 设置Prometheus告警规则
            sh '''
                curl -X POST "http://prometheus:9090/api/v1/rules" \
                  -H "Content-Type: application/json" \
                  -d @alert-rules.json
            '''
        }
    }
}

🧪 基于Jenkins的自动化测试体系搭建

2.1 多层次测试策略

测试金字塔听说过吗？让我们用Jenkins把它实现出来！

groovy:test-pyramid-pipeline 复制代码

    agent any
    
    stages {
        stage('Unit Tests') {

                }
            }
        }
        
        stage('Integration Tests') {
            steps {

2.2 智能测试调度系统

不是所有测试都需要每次都跑，让我们来点智能的！
