This document provides instructions for pulling and running Docker containers for common applications like Nginx, MySQL, WordPress, PostgreSQL, Redis, and GitLab. It demonstrates how to pull base images, define Dockerfiles to customize images, run containers with links and ports, and mount volumes to persist data outside containers.

2. • Traer una imagen remota:
$ docker pull ubuntu
• Listar imágenes del sistema:
