## Qué es una Imagen de Contenedor

Un **contenedor** se ejecuta desde una **imagen de contenedor**.

Una imagen de contenedor es una versión **estática** de todos los archivos, variables de entorno y el comando/programa por defecto que debería estar presente en un contenedor. **Estático** aquí significa que la imagen de contenedor **no se está ejecutando**, no está siendo ejecutada, son solo los archivos empaquetados y los metadatos.
