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

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

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.
