这个文件配置 Traefik 使用路径前缀 `/api/v1`。

然后，它把请求重定位到运行在 `http://127.0.0.1:8000` 上的 Uvicorn。

现在，启动 Traefik：

<div class="termy">

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

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

</div>

接下来，使用 Uvicorn 启动应用，并使用 `--root-path` 选项：

<div class="termy">

```console
$ uvicorn main:app --root-path /api/v1
