Microservices Java Spring-boot app + Docker + Kubernetes

This project consists of an e-commerce application built with microservices using Spring Boot in Java 21 and Maven 4.0.0. The application is divided into three microservices: Shopfront (frontend), Product Catalogue (product catalog), and Stock Manager (inventory management). Additionally, a directory with YAML files for service deployment is included.
