DevOps CI/CD Pipeline with Kubernetes Deployment

Project Overview This project demonstrates a complete DevOps workflow by containerizing a Flask application with MySQL, deploying it on Kubernetes, and automating the CI/CD pipeline using GitHub Actions.

Architecture User → Ingress → Flask Service → Flask Pod → MySQL Service → MySQL Pod

Tech Stack Docker Kubernetes (Minikube) GitHub Actions Flask (Python) MySQL

Features Containerized Flask + MySQL application Kubernetes Deployments and Services Ingress configuration for external access CI/CD pipeline for automated build and push Secure handling of environment variables and secrets

CI/CD Pipeline

• Code pushed to GitHub
• GitHub Actions workflow triggers
• Docker image is built automatically
• Image is pushed to Docker Hub

Project Structure flask-deployment.yaml flask-service.yaml mysql-deployment.yaml mysql-service.yaml ingress.yaml Dockerfile docker-compose.yml .github/workflows/ci.yml

How to Run Locally 1.Start Minikube minikube start --driver=docker

2. Enable Ingress minikube addons enable ingress

3. Apply Kubernetes Config kubectl apply -f .

4. Run Tunnel minikube tunnel

5. Update Hosts File Add this line: 192.168.49.2 myapp.local

6. Access Application http://myapp.local
