DTE-DNBO-API

API allow To integrate both DNBO0.5 & DNBO1.0 in single API on the k8s platform (single EndPoint) which will be used later as a communication interface with DNBO system and all other external/internal systems such as VAS, Snoc, DBSS

API Architecture

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

You need to install the fellowing software in order to get the api up and running

• Node.js and npm
• Docker
• Kubernetes on cloud

Development environment

• Download and Install node.js and NPM from https://nodejs.org/en/download/

Running node.js api

• Download or clone the project code from https://github.com/abdm64/DNBO-API-JS

• Install all required npm packages by running npm install from the command line in the api folder (where the package.json is located).

• Start the api by running npm start from the command line in the api folder, you should see the message Server listening on port 3000. You can test the api directly using an application such as Postman or you can test it with one of the page web.

Testing environment with Docker

• Download and install docker in your machine

• inside the root folder run the fellowing cammand

$docker-compose up 

and now the server live on the port 80 using nginx instance

Docker image

• Build your own docker image and push it to your repo by running "docker build -t my-app-name:v1 . " from the cammand line in api folder you can push it to your own registy

Production environment

• Deploying this app on kubernetes system can be so easy by applying the k8s yaml files, make sure that you upload the app image to the docker hub or private registry and change the image name config in dnbo-dep.yaml , then run "sudo kubectl apply -f k8s" from the cammand line in the root folder.

• PS : you must install NGINX Ingress Controller on your k8s cluster before applying the final deployment please check this link https://kubernetes.github.io/ingress-nginx/deploy/ for more information

Deployment Architecture

Deployment Architecture Explaind

in the final deplyment we have two separted application the main api ( dte-dnbo-api ) and the front appliaction to control the main api (not ready yet ) we create ingress service and multiple replicas for the dnbo-api because we expect a large amount of traffic per second ( 1000 req per second )
