网站使用Docker运行
买了个腾讯云的主机玩，顺便把网站签过去，迁移觉得很麻烦，搞成容器直接run就可以了。
于是就直接搞。
docker search 发现有打好的fastapi镜像，但是还是自己动手用官方的python3镜像自己做踏实。
```
#基础镜像
FROM 3.9.13-slim-bullseye
#工作目录
WORKDIR /www
#安装依赖包
COPY requirements.txt ./
RUN pip install requirements.txt
EXPOSE 8000 8000
CMD["gunicorn","xxx.main:app","-w","4","-k","uvicorn.workers.UvicornWorker","-D","-b","127.0.0.1:8080"]
```
