+# ingress-nginx
+
+**ingress-nginx** es un controlador de Ingress para Kubernetes basado en NGINX. Se utiliza para gestionar el acceso externo a los servicios en un clúster de Kubernetes, proporcionando balanceo de carga, terminación SSL y enrutamiento basado en host y ruta.
+
+## Características principales
+
+- **Balanceo de carga**: Distribuye el tráfico entrante entre múltiples réplicas de un servicio.
+- **Terminación SSL**: Maneja la terminación SSL/TLS para asegurar las conexiones.
+- **Enrutamiento basado en host y ruta**: Permite definir reglas para enrutar el tráfico a diferentes servicios basados en el host y la ruta de la solicitud.
+
+## Instalación
+
+Para instalar **ingress-nginx** en un clúster de Kubernetes, puedes usar Helm:
+
+```bash
+helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
+helm repo update
+helm install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx --create-namespace
