# Script: create_kind_cluster.sh
|
||
|
|
# Descripción: Este script automatiza la creación de un clúster de Kubernetes utilizando Kind (Kubernetes en Docker).
|
||
|
|
# También configura un registro Docker local y lo conecta al clúster para permitir el uso de un registro local
|
||
|
|
# para las imágenes de contenedor. Además, instala el controlador Ingress NGINX en el clúster para manejar recursos de ingreso.
