|
||
|
||
## Docker 配置
|
||
|
||
### docker-compose.yml 环境变量
|
||
|
||
```yaml
|
||
version: '3.8'
|
||
|
||
services:
|
||
web:
|
||
environment:
|
||
- VITE_API_URL=http://api:8080
|
||
|
||
api:
|
||
environment:
|
||
- DATABASE_URL=postgresql://postgres:password@db:5432/ras
|
||
- REDIS_URL=redis://redis:6379/0
|
||
- SECRET_KEY=${SECRET_KEY}
|
||
|
||
engine:
|
||
environment:
|
||
- BACKEND_URL=http://api:8080
|
||
- LOG_LEVEL=INFO
|
||
```
|
||
|
||
### 使用 .env 文件
|
||
|
||
在项目根目录创建 `.env`：
|
||
|
||
```env
|
||
# Docker Compose 会自动加载
|
||
SECRET_KEY=your-secret-key-at-least-32-chars
|
||
POSTGRES_PASSWORD=secure-db-password
|
||
```
|
||
|
||
---
|
||
|
||
## 配置优先级
|
||
|
||
配置按以下优先级加载（高优先级覆盖低优先级）：
|
||
|
||
```
|
||
1. 命令行参数（最高）
|
||
2. 环境变量
|
||
3. .env 文件
|
||
4. 配置文件 (yaml)
|
||
5. 代码默认值（最低）
|
||
```
|
||
|
||

|
||
|
||
## 敏感配置管理
|
||
|
||
!!! danger "安全提醒"
|
||
不要将敏感信息提交到代码仓库！
|
||
|
||
### 推荐做法
|
||
|
||
1. **使用 .env 文件**，并将其加入 `.gitignore`
|
||
2. **使用环境变量**，通过 CI/CD 注入
|
||
3. **使用密钥管理服务**，如 AWS Secrets Manager、HashiCorp Vault
|
||
|
||
### .gitignore 配置
|
||
|
||
```gitignore
|
||
# 环境配置文件
|
||
.env
|
||
.env.local
|
||
.env.*.local
|
||
|
||
# 敏感数据目录
|
||
/secrets/
|
||
*.pem
|
||
*.key
|
||
```
|
||
|
||
---
|
||
|
||
## 配置验证
|
||
|
||
启动服务前验证配置是否正确：
|
||
|
||
```bash
|
||
# 验证 API 服务配置
|
||
cd api
|
||
python -c "from app.config import settings; print(settings)"
|
||
|
||
# 验证 Engine 配置
|
||
cd engine
|
||
python -c "from config import settings; print(settings)"
|
||
```
|
||
|
||

|
||
|
||
## 下一步
|
||
|
||
- [安装部署](index.md) - 开始安装服务
|
||
- [Docker 部署](../deployment/docker.md) - 容器化部署
