## `fastapi run` { #fastapi-run }

Executing `fastapi run` starts FastAPI in production mode.

By default, **auto-reload** is disabled. It also listens on the IP address `0.0.0.0`, which means all the available IP addresses, this way it will be publicly accessible to anyone that can communicate with the machine. This is how you would normally run it in production, for example, in a container.

## `fastapi run` { #fastapi-run }

Executar `fastapi run` inicia o FastAPI em modo de produção.

Por padrão, o **recarregamento automático** está desativado. Ele também escuta no endereço IP `0.0.0.0`, o que significa todos os endereços IP disponíveis; dessa forma, ficará acessível publicamente para qualquer pessoa que consiga se comunicar com a máquina. É assim que você normalmente o executaria em produção, por exemplo, em um contêiner.

Die IP `0.0.0.0` wird üblicherweise verwendet, um anzudeuten, dass das Programm alle auf diesem Computer/Server verfügbaren IPs abhört.

## `fastapi run` { #fastapi-run }

`fastapi run` を実行すると、デフォルトで本番モードで起動します。

デフォルトでは、**auto-reload** は無効です。また、IP アドレス `0.0.0.0`（利用可能なすべての IP アドレスを意味します）で待ち受けるため、そのマシンと通信できる任意のクライアントから公開アクセスが可能になります。これは、たとえばコンテナ内など、本番環境で一般的な実行方法です。

多くの場合（そして推奨されるのは）、上位に HTTPS を終端する「termination proxy」を置きます。これはアプリのデプロイ方法に依存し、プロバイダが代行する場合もあれば、自分で設定する必要がある場合もあります。
