Fibonacci Series Generator using Multi-Container Architecture of Docker

User Interface has been bootstrapped with Create React App.

This is a demo app built with an intention to successfully deploy a multi-container docker app on AWS BEANSTALK and can be served to end user.

Note: You can also deploy this app on your localhost by just using Docker-compose.yml present in the root directory of this project, it will get deployed on NGINX server

How to use the project:

• Clone the repository
• Navigate to the root directory of the project in your terminal
• For deployment on you localhost:
  • run command "docker-compose up --build"
  • Access the application on localhost:3050
• For deployment on AWS:
  • Setup Travis-CI
  • Setup AWS and it's services
  • Go to Elastic Beanstalk application and click on the URL provided for accessing the application over there

Steps to setup Travis-CI and AWS can be found here
