A production-style microservices application demonstrating modern DevOps practices including Docker containerization, Kubernetes orchestration, Helm deployments, and environment-based configuration management.
The application implements secure authentication, user-scoped dashboards, and dynamic profile management using JWT, deployed through a fully containerized microservices architecture.
DevOps Task Manager is a multi-user web application built with:
- 🐍 Flask – Authentication service
- 🌐 Nginx – Reverse proxy + frontend server
- 🍃 MongoDB – Persistent database
- 🐳 Docker – Containerization
- ☸️ Kubernetes – Container orchestration
- ⚙️ Helm – Kubernetes package management
- 🏗 Infrastructure as Code Ready – Terraform-compatible structure
Snapshots:-
The application allows users to:
✔ Register securely
✔ Login using JWT authentication
✔ Access a personalized dashboard
✔ Add and manage skills dynamically
✔ Persist user data across container restarts
✔ Deploy the application using Kubernetes and Helm

The application follows a microservices-based design.
| Service | Technology | Purpose |
|---|---|---|
| Frontend | Nginx | Serves UI and acts as reverse proxy |
| Auth Service | Flask | Handles authentication & API logic |
| Database | MongoDB | Stores users and skills |
| Deployment | Kubernetes | Orchestrates containers |
| Packaging | Helm | Manages Kubernetes application deployments |
Services communicate through internal Kubernetes networking.

git clone https://github.com/your-repo/devops-task-manager.git
cd devops-task-manager
2️⃣ Start Containers
docker compose up --build
3️⃣ Access Application
http://localhost
☸️ Kubernetes Deployment
Apply Kubernetes manifests:
kubectl apply -f k8s/
Verify deployment:
kubectl get pods
kubectl get svc
kubectl get ingress
⚙️ Helm Deployment
Helm packages the entire application for easy deployment.
Install Application
helm install task-dev ./task-manager-chart -f task-manager-chart/values-dev.yaml
Upgrade Deployment
helm upgrade task-dev ./task-manager-chart -f task-manager-chart/values-dev.yaml
Uninstall Deployment
helm uninstall task-dev
helm upgrade task-dev ./task-manager-chart -f task-manager-chart/values-dev.yaml
Uninstall Deployment
helm uninstall task-dev
Deploy Production
helm install task-prod ./task-manager-chart -f values-prod.yaml
Each environment can have different:
replicas
domain names
resource limits
environment variables
