Usando una imagen de contenedor pre-hecha es muy fácil **combinar** y utilizar diferentes herramientas. Por ejemplo, para probar una nueva base de datos. En la mayoría de los casos, puedes usar las **imágenes oficiales**, y simplemente configurarlas con variables de entorno.

By using a pre-made container image it's very easy to **combine** and use different tools. For example, to try out a new database. In most cases, you can use the **official images**, and just configure them with environment variables.

DIR:
  DIR points to a directory on a filesystem. When you want to combine
  multiple drives into a single large system, pass one directory per
