DevOps Challenge

My solution for a technical challange made for upcoming Jr DevOps/SRE Engineers at the green bank💚

How to Run

docker compose build
docker compose up --build

The web page will be hosted at https://localhost:5000/

Test on terminal

Test the API health

curl.exe http://localhost:8082/health

Should return up

Writer

Invoke-WebRequest -Method POST -Uri http://localhost:8083/write -Body "hello"

Reader

Invoke-WebRequest http://localhost:8082/data

Architecture

Stack

• Frontend: HTML/CSS, Bootstrap, JavaScript, Node.JS
• Backend: Python, GO
• Database: Redis

Containers

The docker-compose.yaml will create & orchestrate 4 containers:

• devops-challenge-web-1 - Web Service
• devops-challenge-writer-1 - Writer Service
• devops-challenge-reader-1 - Reader Service
• devops-challenge-redis-1 - Redis Database

Service Ports

• Web/Front: http://localhost:5000/
• Reader: http://localhost:8082/
• Writer: http://localhost:8083/
• Redis: http://localhost:6379/

Flow

The user (using the Web Service (Node.JS)) can send or request data from the redis

• Send: Writer Service (python) writes on Redis and returns a code 201 to Web Service (Node.JS)
• Request: Reader Service (GO) reads from Redis and returns its data to Web Service (Node.JS)
