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.

• productcatalogue

  • The 'product catalogue' microservice of the DJShopping example application, which provides product details like name and price stockmanager
  • The 'stock manager' microservice of the DJShopping example application, which provides stock information, such as SKU and quantity

• prepare-app.sh: script to prepare the application and create all related services.

• remove-app.sh: remove the application and all related services.

• Docker compose & Docker files.
