Overengineered Fibonacci Sequnce Calculator

Multi-Docker Fibonacci Sequence Calculator

Part of this course

• React/Express App
• Postgres DB maintains keys already calculated
• Redis maintains results indices-value pairs, or contacts Node.js worker to calculate new values

Project Overview

Project Flow

End Deployed Structure

Environment Vars

• Yellow: Constant Values
• Red: URL vals that tell multi-server and multi-worker how to connect to services

Volumes

If the pod is destroyed the volume is destroyed

Don't have multiple postgres containers accessing the same volume by incrementing replicas

Ingress Controller

• routing rules to get traffic to services

This project uses ingress-nginx

After Deployment go to Google cloud dashboard -> Clusters -> Services

Travis workflow:

EBS file

• Dockerrun.aws.json -> config file for Elastic Beanstalk, similar to docker-compose
