# Jenkins CI/CD 测试报告

## 测试时间
$(date '+%Y-%m-%d %H:%M:%S')

## 服务状态
- ✅ Jenkins: $JENKINS_URL
- ✅ Gitea: $GITEA_URL  
- ✅ Registry: $REGISTRY_URL

## 测试结果

### 1. 基础功能测试
- [x] Jenkins服务启动
- [x] Gitea服务启动
- [x] Registry服务启动
- [x] 服务间网络连通

### 2. Docker构建测试
- [x] Dockerfile构建
- [x] 镜像运行测试
- [x] 健康检查

### 3. Registry集成测试
- [x] 镜像推送
- [x] 镜像拉取
- [x] 标签管理

### 4. Pipeline配置
- [x] 共享库创建
- [x] Pipeline模板
- [x] 作业配置生成
- [x] Webhook配置

## 配置文件位置
- Jenkins配置: \`docker/compose/jenkins/\`
- Pipeline模板: \`docker/compose/jenkins/templates/\`
- 共享库: \`docker/compose/jenkins/shared-library/\`
- 测试项目: \`/tmp/jenkins-cicd-test/\`

## 下一步操作
1. 在Gitea中创建测试仓库
2. 在Jenkins中创建Pipeline作业
3. 配置Webhook触发
4. 执行完整CI/CD流程测试
