Introducción a Docker

Warning: This information may be outdated. Please note the date of the post.

En este post vamos a dar una breve introducción de Docker:

¿Qué son los contenedores?

Son diferentes compartimentos aislados dentro de un solo sistema operativo y actúan como máquinas virtuales aunque no lo son, con esto nos referimos a que comparten muchas de las mismas características de una maquina virtual (seguridad, almacenamiento, aislamiento de redes, entre otras…), pero comparten el mismo kernel.
Las ventajas más importantes en comparación a una mv son:
  • Requieren menos recursos de hardware.
  • Son más rápidos de iniciar y finalizar.
  • Aislan librerías.
  • Facilitan el control de versiones y gestión de las mismas.
  • Minimiza el tiempo de ejecución en CPU y Almacenamiento gestionado por una aplicación, como por ejemplo al actualizar la aplicación.

¿Qué es Docker?

Docker significa ’estibador’, que si lo llevamos a un campo general es ’el que mueve los contenedores en el puerto’, le viene al pelo el nombre ¿no crees?.
