继 Heroku、Railway 收费后，能免费使用（好用）的网站托管服务还剩下 Vercel和 Huggingface。
但 Vercel 不支持 docker deployment，huggingface 限制则很少。
unlimited！
确实良心。
配置文件
官方文档其实很清晰了，这里简单贴一下没有读写权限问题的 FastAPI Server 配置。

必须要有 app.py 才能运行服务。

外网连通性
当使用私有域名进行数据交互的时候，无法从容器内发送请求到外部，而本地不同网络下测试是正常的。
可能是 bug。

目前只能通过 IP:PORT 的方式处理数据。
Secret
如果要在部署环境使用敏感信息，可以在环境变量添加 ACCESS_TOKEN 后在 [[huggingface 部署 docker 环境#Dockerfile]] 加入下面的内容：

|
RUN --mount=type=secret,id=ACCESS_TOKEN,mode=0444,required=true \
curl test -H 'Authorization: Bearer $(cat /run/secrets/ACCESS_TOKEN)'
|
如果更改 Secret 变量名，记得删掉原来重名的变量（系统变量调用顺序自上而下）。
