+# Docker 部署指南（硬编码 KEY 版本）
+
+## 📋 配置说明
+
+本 Dockerfile 已经将所有 API 配置和密钥硬编码在镜像中：
+
+### 已硬编码的配置
+
+| 配置项 | 值 |
+|--------|-----|
+| API 端点 | `https://api.coze.cn/v1` ✅（包含 /v1 前缀） |
+| COZE_API_KEY | `Bearer eyJhbGci...` ✅ |
+| LLM_API_KEY | `Bearer eyJhbGci...` ✅ |
+| COZE_WORKSPACE_ID | `7622238752642957347` ✅ |
+| LLM_MODEL_NAME | `doubao-seed-2-0-pro-260215` ✅ |
+
+### Workspace ID 来源
+
+从 JWT Token 的 `sub` 字段提取：
+```
+spiffe://api.coze.cn/workload_identity/id:7622238752642957347
+```
+
+## 🚀 快速部署
+
+### 步骤 1：构建镜像
+
+```bash
+# 进入项目根目录
+cd /workspace/projects
+
+# 构建镜像
+docker build -t math-grading:latest .
+```
+
+### 步骤 2：运行容器
+
+```bash
+# 运行容器（简单方式）
+docker run -d \
+  --name math-grading \
+  -p 8000:8000 \
+  --restart unless-stopped \
+  math-grading:latest
+
+# 运行容器（完整方式，挂载日志和缓存）
+docker run -d \
+  --name math-grading \
+  -p 8000:8000 \
+  -v $(pwd)/logs:/app/work/logs \
+  -v $(pwd)/cache:/tmp/homework_cache \
+  --restart unless-stopped \
+  math-grading:latest
+```
+
+### 步骤 3：验证服务
+
+```bash
+# 查看容器状态
+docker ps | grep math-grading
+
+# 查看日志
+docker logs -f math-grading
+
+# 检查健康状态
+curl http://localhost:8000/health
+```
+
+## 🧪 测试接口
+
+### 测试 LLM 调用
+
+```bash
+curl -X POST http://localhost:8000/stream_run \
+  -H "Content-Type: application/json" \
+  -d '{
+    "student_homework": [
+      {
+        "student_id": 1,
+        "student_name": "测试学生",
+        "homework_images": [
+          "https://dpcclass.oss-cn-beijing.aliyuncs.com/umsupload/2026/03/18/69baa4f5-4826-4901-00e1-c6e66f02947f.jpg?x-oss-process=image/resize,w_1000"
+        ]
+      }
+    ],
+    "answer_doc_url": "",
+    "comment_max_length": 50,
+    "max_concurrent": 1
+  }'
+```
+
+### 测试多图片批改
+
+```bash
+curl -X POST http://localhost:8000/stream_run \

+    "comment_max_length": 50,
+    "max_concurrent": 2
+  }'
+```
+
+## 🔧 常用命令
+
+### 容器管理
+
+```bash
+# 停止容器
+docker stop math-grading
+
+# 启动容器
+docker start math-grading
+
+# 重启容器
+docker restart math-grading
+
+# 删除容器
+docker rm -f math-grading
+
+# 删除镜像
+docker rmi math-grading:latest
+```
+
+### 日志查看
+
+```bash
+# 查看实时日志
+docker logs -f math-grading
+
+# 查看最近 100 行日志
+docker logs --tail 100 math-grading
+
+# 查看错误日志
+docker logs math-grading 2>&1 | grep ERROR
+```
+
+### 进入容器
+
+```bash
+# 进入容器 shell
+docker exec -it math-grading /bin/bash
+
+# 查看环境变量
+docker exec math-grading env | grep COZE
+
+# 运行 Python 脚本
+docker exec math-grading python assets/check_env.py
+```
+
+## 📊 验证配置成功
+
+### 成功标志
+
+1. **容器启动成功**
+   ```bash
+   docker ps | grep math-grading
+   # 应该显示容器运行中（Up status）
+   ```
+
+2. **日志无错误**
+   ```bash
+   docker logs math-grading | grep ERROR
+   # 不应该有认证错误（401）或端点错误（404）
+   ```
+
+3. **健康检查通过**
+   ```bash
+   curl http://localhost:8000/health
+   # 应该返回 200 OK
+   ```
+
+4. **LLM 调用成功**
+   ```bash
+   # 运行测试请求，日志应该显示：
+   # ✅ HTTP Request: POST https://api.coze.cn/v1/chat/completions "HTTP/1.1 200 OK"
+   ```
+
+### 错误排查
+
+#### 错误 1：容器无法启动
+
+```bash
+# 查看详细日志
+docker logs math-grading
+
+# 检查端口是否被占用
+netstat -tuln | grep 8000
+```
+
+#### 错误 2：LLM 调用 401 错误
+
+```bash
+# 检查环境变量是否正确设置
+docker exec math-grading env | grep COZE_API_KEY
+
+# 应该看到：
+# COZE_API_KEY=Bearer eyJhbGci...
+```
+
+#### 错误 3：LLM 调用 404 错误
+
+```bash
+# 检查 API 端点配置
+docker exec math-grading env | grep BASE_URL
+
+# 应该看到：
+# COZE_INTEGRATION_BASE_URL=https://api.coze.cn/v1
+# 注意要有 /v1 前缀
+```
+
+## 🔐 安全说明
+
+### ⚠️ 密钥已硬编码
+
+当前 Dockerfile 将 API Key 硬编码在镜像中：
+- ✅ 优点：部署简单，无需额外配置
+- ❌ 缺点：密钥会暴露在镜像中，存在安全风险
+
+### 安全建议
+
+1. **私有仓库**
+   - 使用私有 Docker Registry（如阿里云容器镜像服务）
+   - 不要将镜像推送到公共仓库
+
+2. **访问控制**
+   - 限制镜像访问权限
+   - 使用 RBAC 控制镜像拉取
+
+3. **定期更换密钥**
+   - 定期在 Coze 平台更换 API Key
+   - 重新构建镜像
+
+4. **生产环境建议**
+   - 使用环境变量方式（推荐）
+   - 参考 `assets/docker-compose.yml`
+

+  ```
+
+## 🔧 常用命令
+
+### 容器管理
+
+```bash
+# 查看状态
+docker ps | grep math-grading
+
+# 查看日志
+docker logs -f math-grading
+
+# 停止服务
+docker stop math-grading
+
+# 启动服务
+docker start math-grading
+
+# 重启服务
+docker restart math-grading
+
+# 进入容器
+docker exec -it math-grading /bin/bash
+```
+
+## 📊 API 接口
+
+### 批改接口
+
+**请求**:
+```bash
+curl -X POST http://localhost:8000/stream_run \
+  -H "Content-Type: application/json" \
+  -d '{
+    "student_homework": [
+      {
+        "student_id": 1,
+        "student_name": "张三",
+        "homework_images": [
+          "https://example.com/image1.jpg",
+          "https://example.com/image2.jpg"
+        ]
+      }
+    ],
+    "answer_doc_url": "https://example.com/answers.docx",
+    "comment_max_length": 50,
+    "max_concurrent": 5
+  }'
+```
+
+**参数说明**:
+- `student_homework`: 学生作业列表
+- `answer_doc_url`: 答案文档 URL（可选）
+- `comment_max_length`: 评语最大字数（默认 50）
+- `max_concurrent`: 并发批改数量（默认 5）

+## 🔍 故障排查
+
+### 问题 1: 容器无法启动
+
+```bash
+# 查看详细日志
+docker logs math-grading
+
+# 检查端口占用
+netstat -tuln | grep 8000
+```
+
+### 问题 2: LLM 调用失败
+
+```bash
+# 检查环境变量
+docker exec math-grading env | grep COZE
+
+# 应该看到:
+# COZE_API_KEY=Bearer eyJhbGci...
+# COZE_WORKSPACE_ID=7622238752642957347
+# COZE_INTEGRATION_BASE_URL=https://api.coze.cn/v1
+```
+
+### 问题 3: 认证错误 (401)
+
+- 确认 COZE_API_KEY 和 COZE_WORKSPACE_ID 都已设置
+- 检查 Token 是否有效
+
+### 问题 4: 端点错误 (404)
+
+- 确认 API 端点包含 /v1 前缀
+- 检查 COZE_INTEGRATION_BASE_URL 配置
+
+## 📚 详细文档
+
+- [完整部署指南](DOCKER_DEPLOY.md)
+- [项目文档](AGENTS.md)
+- [Docker 404 错误修复](assets/fix_docker_404.md)
+
+## ⚠️ 安全提示
+
+当前 Dockerfile 将 API Key 硬编码在镜像中：
+- ✅ 优点：部署简单，无需额外配置
+- ❌ 缺点：密钥会暴露在镜像中
+
+### 安全建议
+
+1. **使用私有仓库**：不要推送到公共 Docker Registry
+2. **访问控制**：限制镜像拉取权限
+3. **定期更换密钥**：在 Coze 平台定期更换 API Key
+4. **生产环境**：考虑使用环境变量方式（参考 docker-compose.yml）
+
+## 🎯 验证成功标志
+
+部署成功后，应该看到：
+
+```bash
+# 1. 容器运行中
+docker ps | grep math-grading
+# Up 5 minutes
+
+# 2. 健康检查通过
+curl http://localhost:8000/health
+# 200 OK
+
+# 3. 日志无错误
+docker logs math-grading | grep ERROR
+# （无输出）
+
+# 4. LLM 调用成功
+# 日志显示:
+# HTTP Request: POST https://api.coze.cn/v1/chat/completions "HTTP/1.1 200 OK"
+```
+
+## 📞 支持
+
+如遇问题，请：
+1. 查看日志: `docker logs -f math-grading`
+2. 运行测试: `./test.sh`
+3. 参考文档: `DOCKER_DEPLOY.md`
