🗳️ Docker Compose Voting App

A simple distributed application running across multiple Docker containers, featuring Python, .NET, Node.js, and Redis/PostgreSQL for messaging and storage.

🚀 Getting Started

First, install Docker:

• Mac/Windows: Download Docker Desktop (includes Docker Compose).
• Linux: Ensure you have the latest Docker Compose.

🏗️ Running Locally

Build and start the app with:

docker compose up

• The vote app will be available at localhost:8080
• The results app will be available at localhost:8081

🌍 Running on Docker Swarm

If you don’t have a swarm initialized, do this first:

docker swarm init

Then deploy the app:

docker stack deploy --compose-file docker-stack.yml vote

---

🏗️ Run in Kubernetes

The folder k8s-specifications contains YAML files for deploying the Voting App.

Deploy in Kubernetes:

kubectl create -f k8s-specifications/

• Vote app: Accessible on port 31000 of each cluster node.
• Result app: Accessible on port 31001.

Remove deployments:

kubectl delete -f k8s-specifications/

Components:

• 🐍 Python (vote) – Frontend voting web app
• 🔄 Redis – Collects new votes
• 🏗️ .NET (worker) – Consumes votes and stores them in PostgreSQL
• 🗄️ PostgreSQL – Persistent database backed by a Docker volume
• 🟢 Node.js (result) – Real-time results display

---

🔎 Notes

• Each browser only registers one vote per session.
• This is not a fully optimized distributed architecture—it’s a simple demonstration.
