+\# 📦 go-sync-service
+
+
+
+\*\*go-sync-service\*\* es un microservicio escrito en Go para la ejecución de tareas de sincronización basadas en cron, integrando Redis como sistema de control y configuración dinámica, y PostgreSQL mediante GORM como base de datos. Está diseñado con una arquitectura modular y desacoplada para facilitar su reutilización y escalabilidad.
+
+
+
+---
+
+
+
+\## 🚀 Características
+
+
+
+\- 🔁 Ejecución de tareas periódicas con `robfig/cron`
+
+\- 📦 Carga de configuraciones de tareas desde Redis (configuración dinámica)
+
+\- 🧩 Arquitectura limpia con separación por capas (`ports`, `dto`, `config`, `scheduler`)
+
+\- 🛠️ Servicio desacoplado de sincronización con posibilidad de extensiones
+
+\- 🗂️ Organización clara del código con submódulos reutilizables
+
+\- 🗃️ Persistencia con PostgreSQL vía `gorm.io/gorm`
+
+\- 🧠 Logger centralizado
+
+
+
+---
+
+
+
+\## 🛠️ Requisitos
+
+
+
+\- Go 1.20+
+
+\- Redis
+
+\- PostgreSQL
+
+\- Docker (opcional para despliegue)
+
+
+
+---
+
+
+

+

+
+
+
+\## ▶️ Cómo ejecutar
+
+
+
+\### 1. Clonar el proyecto
+
+
+
+```bash
+
+git clone https://github.com/tuusuario/go-sync-service.git
+
+cd go-sync-service
+
+```
+
+
+
+\### 2. Configurar variables de entorno
+
+
+
+Crear un archivo `.env` o configurar los valores necesarios:
+
+
+
+```env
+
+DB\_HOST=localhost
+
+DB\_PORT=5432
+
+DB\_NAME=sync\_db
+
+DB\_USER=postgres
+
+DB\_PASS=secret
+
+
+
+REDIS\_ADDR=localhost:6379
+
+REDIS\_PASS=
+
+```
+
+
+
+\### 3. Ejecutar el servicio
+
+
+
+```bash
+
+go run cmd/go-sync-service/main.go
+
+```
+
+
+
+---
+
+
+
+\## 🧪 Pruebas
+
+
+
+Puedes lanzar las pruebas (si las implementas) con:
+
+
+
+```bash
+
+go test ./...
+
+```
+
+
+
+---
+
+
+
+\## 📌 Notas técnicas
+
+
+
+\- Las configuraciones de cron (`CronConfigList`) se cargan desde Redis mediante un esquema de deserialización JSON.
+
+\- El archivo `internal/scheduler/manager.go` coordina la carga y reinicio dinámico de tareas cuando hay cambios en la configuración Redis.
+
+\- La interfaz `RedisConfigProvider` permite desacoplar la fuente de datos de configuración, haciéndolo fácilmente intercambiable.
