+# Item 2 – Application Containerization (Docker)
+
+Este documento complementa el README original **sin modificar el código fuente**.  
+Se publican dos imágenes en Docker Hub y se provee `docker-compose` para ejecutar la app.
+
+## Imágenes públicas
+- Web: https://hub.docker.com/r/jcabo65/php-sample-web
+- DB:  https://hub.docker.com/r/jcabo65/php-sample-db
+
+## Archivos relevantes en este repo
+- `docker/Dockerfile.web` – imagen PHP/Apache de la aplicación.
+- `docker/Dockerfile.db`  – imagen de base (MariaDB).
+- `docker/docker-compose.yml` – orquesta `web` y `db` usando **las imágenes públicas**.
+- `docker/docker-compose.override.yml` – comparte `/var/run/mysqld` para que la app (que usa `host=localhost`) conecte por **socket** sin cambiar código.
+
+## Requisitos
+- Docker + Docker Compose.
+
+## Cómo ejecutar (2 líneas)
+```bash
+docker compose -f docker/docker-compose.yml -f docker/docker-compose.override.yml up -d
+# abrir http://localhost:8080
