FastMCP 案例九（Docker部署）

1、目录结构

 2、在src同级目录创建一个Dockerfile，内容如下：

# 使用官方 Python 3.11 基础镜像
FROM python:3.11-slim

# 设置工作目录
WORKDIR /app

# 安装依赖（fastmcp 会自动装好 uvicorn、starlette 等）
RUN pip install --no-cache-dir fastmcp

# 把代码拷进去
COPY src/  /app

# 默认用 SSE 方式启动
CMD ["python", "./mcp/server-sse.py"]

3、编译容器

docker build -t mcp-server-sse .
