========================================
|
||||
Gerrit 与 Jenkins 集成配置指南
|
||||
========================================
|
||||
|
||||
1. 访问 Jenkins Web 界面
|
||||
URL: http://${GERRIT_HOST}:${JENKINS_PORT}
|
||||
|
||||
2. 使用初始密码登录（见上方输出）
|
||||
|
||||
3. 安装 Gerrit Trigger 插件
|
||||
- 管理 Jenkins → 插件管理 → 可用插件
|
||||
- 搜索 "Gerrit Trigger"
|
||||
- 安装并重启 Jenkins
|
||||
|
||||
4. 配置 Gerrit Server
|
||||
- 管理 Jenkins → 系统配置 → Gerrit Trigger
|
||||
- 添加 Gerrit Server:
|
||||
* Name: Gerrit-Server
|
||||
* Frontend URL: http://${GERRIT_HOST}:${GERRIT_PORT}
|
||||
* SSH Port: ${GERRIT_SSH_PORT}
|
||||
* Username: admin（或您的 Gerrit 用户名）
|
||||
* SSH Keyfile: /var/lib/jenkins/.ssh/id_rsa
|
||||
|
||||
5. 配置 SSH 密钥
|
||||
- 确保 Jenkins 用户有访问 Gerrit 的 SSH 密钥
|
||||
- 将您的 SSH 私钥复制到: /var/lib/jenkins/.ssh/id_rsa
|
||||
- 设置权限: sudo chown jenkins:jenkins /var/lib/jenkins/.ssh/id_rsa
|
||||
- 设置权限: sudo chmod 600 /var/lib/jenkins/.ssh/id_rsa
|
||||
|
||||
6. 测试连接
|
||||
- 在 Gerrit Trigger 配置中点击 "Test Connection"
|
||||
- 如果成功，会显示 Gerrit 版本信息
|
||||
|
||||
7. 创建流水线任务
|
||||
- 新建任务 → 流水线
|
||||
- 在 Pipeline 脚本中配置 Gerrit Trigger
|
||||
|
||||
示例 Pipeline 脚本:
|
||||
pipeline {
|
||||
agent any
|
||||
triggers {
|
||||
gerrit(
|
||||
serverName: 'Gerrit-Server',
|
||||
events: [changeMerged(), patchsetCreated()],
|
||||
project: 'plain:.*',
|
||||
branch: 'plain:.*'
|
||||
)
|
||||
}
|
||||
stages {
|
||||
stage('构建') {
|
||||
steps {
|
||||
sh 'echo "开始构建..."'
|
||||
}
|
||||
}
|
||||
}
|
||||
}

||||
