Именно как и хотелось. ✔️

Это потому, что FastAPI использует `root_path`, чтобы создать в OpenAPI сервер по умолчанию с URL из `root_path`.

## Дополнительные серверы { #additional-servers }

/// warning | Предупреждение

Это более продвинутый сценарий. Можно пропустить.

По умолчанию FastAPI создаёт в схеме OpenAPI `server` с URL из `root_path`.

Саме так, як ми хотіли. ✔️

Це тому, що FastAPI використовує `root_path`, щоб створити типовий `server` в OpenAPI з URL, наданою `root_path`.

## Додаткові сервери { #additional-servers }

/// warning | Попередження

Це більш просунутий випадок використання. Можете пропустити його.

- API requests to deprecated versions now receive a warning header in the API response, and cause a metric indicating use of a deprecated API to be published:
  - `kubectl` outputs warnings to stderr, and accepts a `--warnings-as-errors` option to treat warnings as fatal errors

- Kubeadm: perform pre-flight validation on host/node name upon `kubeadm init` and `kubeadm join`, showing warnings on non-compliant names ([#99194](https://github.com/kubernetes/kubernetes/pull/99194), [@pacoxu](https://github.com/pacoxu))
