=================================
DevOps Project Setup (3 Tier)
=================================

=> Our application contains 3 layers

		1) Database (MySQL)

		2) Backend (Java SpringBoot)

		3) Frontend (Angular)

===========
DB Setup
===========

Step-1: Setup AWS RDS MySQL Instance and note down DB details

		DB Endpoint : database-2.cnys8a2a2umm.ap-south-1.rds.amazonaws.com
		DB Username : admin
		DB Password : admin4321
		DB Initial Name : ashokit_ecomm

Step-2: Connect with MySQL DB using Workbench s/w and execute sql queries to insert products data into db tables.

Note: DB Queries file available in backend_app git repo

# Backend App Git Repo : https://github.com/ashokitschool/01_products_api.git

	DB Queries File Name: DB_Setup.sql

DevOps Tools Setup
===================

### DevOps Tools Integration Document : https://github.com/ashokitschool/DevOps-Documents/blob/main/10-Jenkins-Docker-K8S.md


=======================
Backend App Deployment
=======================

Step-1 : Configure RDS DB instance connectivity Details in backend app git repo
	
	File to change : src/main/resources/application.properties

Step-2 : Create CI CD Pipeline to deploy backend application

	Stage-1 : Clone git repo

	Stage-2 : Maven Build

	Stage-3 : Create Docker Image

	Stage-4 : Push docker image to docker hub

	Stage-5 : K8S Deployment	

Step-3 : Access Backend API in browser using LBR url

	URL : http://LBR-URL/api/products


Note: If you are able to see products data in json format then your backend app is running successfully.

Frontend App Deployment
=========================

# Frontend App Git Repo : https://github.com/ashokitschool/ashokit_ecomm_store.git


Step-1 : Configure Backend API LBR Url in frontend application git repo

	File To Configure Bakend URL : ashokit_ecomm_store/src/app/constants.ts

Step-2 : Create CI Job for frontend application

		Stage-1 : Clone git repo

		Stage-2 : Create Docker Image

		Stage-3 : Push Docker Image to Docker hub

Step-3 : Create CD Job for frontend application

		Stage-1 : Clone git repo

		Stage-2 : K8S Deployment
