|
||||
|
||||
## 🔧 三次关键修复
|
||||
|
||||
### 修复1：添加config目录（v1.0 → v1.1）
|
||||
|
||||
**问题**：
|
||||
```
|
||||
Error: ENOENT: no such file or directory, open '/app/config/agents.yaml'
|
||||
```
|
||||
|
||||
**解决**：
|
||||
```dockerfile
|
||||
# Dockerfile 添加：
|
||||
COPY config ./config
|
||||
```
|
||||
|
||||

|
||||
|
||||
---
|
||||
|
||||
### 修复2：条件化pino-pretty（v1.1 → v1.2）
|
||||
|
||||
**问题**：
|
||||
```
|
||||
Error: unable to determine transport target for "pino-pretty"
|
||||
```
|
||||
|
||||
**解决**：
|
||||
```typescript
|
||||
// index.ts 修改：
|
||||
const fastify = Fastify({
|
||||
logger: config.nodeEnv === 'production'
|
||||
? { level: 'info' } // 生产：JSON日志
|
||||
: { level: 'info', transport: {...} } // 开发：pretty格式
|
||||
});
|
||||
```
|
||||
|
||||
**文档**：[14-Node.js后端-pino-pretty问题修复.md](./14-Node.js后端-pino-pretty问题修复.md)
|
||||
|
||||
---
|
||||
|
||||
### 修复3：ES Module适配（v1.2 → v1.3）
|
||||
|
||||
**问题**：
|
||||
```
|
||||
ReferenceError: require is not defined
|
||||
at healthCheck.js:161:43
|
||||
```
|
||||
|
||||
**根源**：
|
||||
```typescript
|
||||
// ❌ ES Module中不能用require
|
||||
loadAverage: require('os').loadavg()
|
||||
```
|
||||
|
||||
**解决**：
|
||||
```typescript
|
||||
// ✅ 使用import
|
||||
import os from 'os'
|
||||
loadAverage: os.loadavg()
|
||||
```
|
||||

|
||||
|
||||
---
|
||||
|
||||
## 🚀 下一步操作
|
||||
|
||||
### 立即操作：更新到v1.3
|
||||
|
||||
1. **登录SAE控制台**：https://sae.console.aliyun.com/
|
||||
2. **找到应用**：nodejs-backend-test
|
||||
3. **更新镜像版本**：
|
||||
```
|
||||
从：backend-service:v1.2
|
||||
改为：backend-service:v1.3
|
||||
```
|
||||

|
||||
## 💡 经验教训
|
||||
|
||||
### 1. Docker镜像完整性检查
|
||||
|
||||
**问题**：忘记复制config目录
|
||||
**教训**：构建前检查清单
|
||||
```bash
|
||||
✅ node_modules
|
||||
✅ dist
|
||||
✅ prisma
|
||||
✅ config ← 容易遗漏！
|
||||
✅ package.json
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. 环境适配
|
||||
|
||||
**问题**：开发工具（pino-pretty）用在生产环境
|
||||
**教训**：根据NODE_ENV条件化配置
|
||||
```typescript
|
||||
config.nodeEnv === 'production' ? A : B
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. ES Module vs CommonJS
|
||||
|
||||
**问题**：混用require()和import
|
||||
**教训**：项目统一使用ES Module，避免require()
|
||||
```typescript
|
||||
// ❌ 不要用
|
||||
const os = require('os')
|
||||
|
||||
// ✅ 使用
|
||||
import os from 'os'
|
||||
```
|
||||

|
||||
|
||||

### 内网地址（重要！）
|
||||
|
||||
```
|
||||
Node.js后端：http://172.17.173.71:3001
|
||||
Python微服务：http://172.17.173.66:8000
|
||||
```
|
||||
|

|
||||
## 📞 后续支持
|
||||
|
||||
### 监控建议
|
||||
|
||||
1. 配置SAE应用监控告警
|
||||
2. 查看实时日志排查问题
|
||||
3. 监控CPU/内存使用率
|
||||
|
||||
### 扩容建议
|
||||
|
||||
如果1核2GB不够：
|
||||
- 推荐：2核4GB（¥120/月）
|
||||
- 配置弹性伸缩（按需扩容）
