+# Docker 部署
+
+Docker 是推荐的部署方式，可以快速启动服务并确保环境一致性。
+
+## 前提条件
+
+- Docker 20.10+
+- Docker Compose 2.0+（可选）
+
+## 构建镜像
+
+### Web 前端
+
+```bash
+docker build -t ai-video-assistant-web ./web
+```
+
+### API 服务
+
+```bash
+docker build -t ai-video-assistant-api ./api
+```
+
+### Engine 服务
+
+```bash
+docker build -t ai-video-assistant-engine ./engine
+```
+
+## 运行容器
+
+### 单独运行
+
+```bash
+# Web 前端
+docker run -d \
+  --name ai-assistant-web \
+  -p 3000:80 \
+  ai-video-assistant-web
+
+# API 服务
+docker run -d \
+  --name ai-assistant-api \
+  -p 8080:8080 \
+  ai-video-assistant-api
+
+# Engine 服务
+docker run -d \
+  --name ai-assistant-engine \
+  -p 8000:8000 \
+  ai-video-assistant-engine
+```
+
+## Docker Compose
+
+推荐使用 Docker Compose 管理多个服务：
+
+```yaml
+version: '3.8'
+
+services:
+  web:
+    build: ./web
+    ports:
+      - "3000:80"
+    environment:
+      - VITE_API_URL=http://api:8080
+    depends_on:
+      - api
+
+  api:
+    build: ./api
+    ports:
+      - "8080:8080"
+    environment:
+      - DATABASE_URL=postgresql://postgres:password@db:5432/ai_assistant
+    depends_on:
+      - db
+
+  engine:
+    build: ./engine
+    ports:
+      - "8000:8000"
+    environment:
+      - BACKEND_URL=http://api:8080
+
+  db:
+    image: postgres:15
+    environment:
+      - POSTGRES_DB=ai_assistant
+      - POSTGRES_PASSWORD=password
+    volumes:
+      - postgres_data:/var/lib/postgresql/data
+
+volumes:
+  postgres_data:
+```
+
+### 启动服务
+
+```bash
+# 启动所有服务
+docker-compose up -d
+
+# 查看日志
+docker-compose logs -f
+
+# 停止服务
+docker-compose down
+```
+
+## 镜像优化
+
+### 多阶段构建
+
+Web 前端 Dockerfile 示例：
+
+```dockerfile
+# 构建阶段
+FROM node:18-alpine AS builder
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci
+COPY . .
+RUN npm run build
+
+# 运行阶段
+FROM nginx:alpine
+COPY --from=builder /app/dist /usr/share/nginx/html
+COPY nginx.conf /etc/nginx/nginx.conf
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
+
+## 健康检查
+
+```yaml
+services:
+  api:
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
+      interval: 30s
+      timeout: 10s
+      retries: 3
+```
+
+## 常见问题
+
+### 容器启动失败
+
+```bash
+# 查看容器日志
+docker logs ai-assistant-web
+
+# 进入容器调试
+docker exec -it ai-assistant-web sh
+```
+
+### 端口冲突
+
+修改 `docker-compose.yml` 中的端口映射，例如 `3001:80`。
