Chef - Ejecución Chef-Cliente

Para probar la ejecución de Chef-Client, necesitamos tener Chef-Client configurado para usar el Chef alojado o nuestro propio servidor alojado.

Inspección del resultado de la última ejecución de Chef-Client

Para verificar la última ejecución de Chef-Client, especialmente los problemas de falla cuando estamos desarrollando un nuevo libro de cocina, necesitamos saber qué salió mal exactamente. Aunque Chef imprime todo en stdout, es posible que desee volver a ver el registro de depuración.

Si queremos probar, necesitamos tener un libro de cocina roto que falla en la compilación.
