# 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.

## Project Structure

 * Simple examples of functional end-to-end tests that use JUnit and REST-assured to test the DJShopping application
 * shopfront
 * The 'shopfront' microservice of the DJShopping example application that provides the primary entry point for the end-user (both Web  UI and API-driven)
 * 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.

## Technologies Used

 * Java 
 * Spring-Boot 3.2.4
 * Maven 4.0.0 
 * jdk v8
 * Docker
 * Kubernetes

## How to run the project

 * Open console prompt 
 * Navigate to docker-Java-kubernetes-project
 * Execute the following command:
    ´´´
    minikube start  #this will initialize the minikube service (kubernetes)
    ´´´
 * Navigate to shopfront folder 
 * Run the following command:   
    ```
    mvn clean install
    ```
 * One the building its finish execute the following command: 
    ```
    docker build -t shopfront:latest . 
    ```
 * Repeat in each folder 
 * Once you finish building all docker images execute: 
    ```
    docker images #to check the images in your system 
    ```
 * Execute the following command on the folder kubernetes   
   ```
    kubectl service file_name.yaml #to start the service, do it with all the services  
   ```
 * Execute the following command
    ```
    minikube service service_name
    ```
    - Do it with all the services, once you open the service productcatalogue got to http://localhost/port/products and the same with  stockmanager -> http:localhost:port/stocks

 * The application shold be running rigth now.
