然後 Traefik 會把它的請求轉發到在 `http://127.0.0.1:8000` 上運行的 Uvicorn。

現在啟動 Traefik：

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml

</div>

然後啟動你的應用，使用 `--root-path` 選項：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1
