Creamos una `HTTPException` que podemos reutilizar (`raise`) más tarde en varios puntos.

Essa prática é tão comum que tem um nome: essas variáveis de ambiente são comumente colocadas em um arquivo `.env`, e o arquivo é chamado de "dotenv".

/// tip | Dica

Um arquivo começando com um ponto (`.`) é um arquivo oculto em sistemas tipo Unix, como Linux e macOS.

Mas um arquivo dotenv não precisa ter exatamente esse nome de arquivo.

s-for-ldap/) for high-availability of the directory service. To use this to find LDAP servers to connect to, an LDAP client makes a DNS SRV record request to the DNS service on a domain that looks like `_service._proto.example.com`. For LDAP the `proto` value is always `tcp`, and `service` is usually `ldap` or `ldaps`.

To enable MinIO to use the SRV records, specify the `srv_record_name` config parameter (or equivalently the `MINIO_IDENTITY_LDAP_SRV_RECORD_NAME` environment variable). This...

Un entorno virtual es un **directorio**, muy similar al global, donde puedes instalar los paquetes para un proyecto.

De esta manera, cada proyecto tendrá su propio entorno virtual (directorio `.venv`) con sus propios paquetes.

De esta forma, los contenedores consumen **pocos recursos**, una cantidad comparable a ejecutar los procesos directamente (una máquina virtual consumiría mucho más).

Los contenedores también tienen sus propios procesos de ejecución **aislados** (normalmente solo un proceso), sistema de archivos y red, simplificando el despliegue, la seguridad, el desarrollo, etc.
