## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.
We'll use secrets to hold the TLS certificate and key. To create a secret, update the paths to `private.key` and `public.crt`
below.

Then type

```sh

* `datetime.timedelta`:
    * Pythonの`datetime.timedelta`です。
    * リクエストとレスポンスでは合計秒数の`float`で表現されます。
    * Pydanticでは「ISO 8601 time diff encoding」として表現することも可能です。<a href="https://docs.pydantic.dev/latest/concepts/serialization/" class="external-link" target="_blank">詳細はドキュメントを参照してください</a>。
* `frozenset`:
    * リクエストとレスポンスでは`set`と同じように扱われます:
        * リクエストでは、リストが読み込まれ、重複を排除して`set`に変換されます。
        * レスポンスでは`set`が`list`に変換されます。

  What is it?
  -----------

  Maven is a software project management and comprehension tool. Based on
  the concept of a Project Object Model (POM), Maven can manage a project's
  build, reporting and documentation from a central piece of information.

# スキーマの追加 - 例

JSON Schemaに追加する情報を定義することができます。

一般的なユースケースはこのドキュメントで示されているように`example`を追加することです。

JSON Schemaの追加情報を宣言する方法はいくつかあります。

## Pydanticの`schema_extra`

<a href="https://docs.pydantic.dev/latest/concepts/json_schema/#schema-customization" class="external-link" target="_blank">Pydanticのドキュメント: スキーマのカスタマイズ</a>で説明されているように、`Config`と`schema_extra`を使ってPydanticモデルの例を宣言することができます:

```Python hl_lines="15 16 17 18 19 20 21 22 23"
