El segundo argumento de <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> es el valor por defecto a retornar.

Si no se proporciona, es `None` por defecto; aquí proporcionamos `"World"` como el valor por defecto para usar.

DockerやKubernetesなどのコンテナを使用している場合は、次の章で詳しく説明します： [コンテナ内のFastAPI - Docker](docker.md){.internal-link target=_blank}

特に**Kubernetes**上で実行する場合は、おそらく**Gunicornを使用せず**、**コンテナごとに単一のUvicornプロセス**を実行することになりますが、それについてはこの章の後半で説明します。
