📝 Notes App (Full DevOps Project)

A full-stack notes application built with Django REST Framework (backend) and React (frontend), fully containerized with Docker, automated using Terraform + Ansible, monitored with a complete observability stack, and scalable with Kubernetes.

🚀 End-to-End DevOps Workflow

Terraform → Create EC2 → Generate Inventory → Ansible → Install Docker → Deploy App

---

⚙️ 1. Infrastructure Setup (Terraform)

cd terraform
terraform init
terraform apply

📤 Outputs

ec2_public_ip = "x.x.x.x"
ec2_username  = "ubuntu"

🔍 Check anytime

terraform output

🧹 Destroy Infra

terraform destroy

👉 Full details: see terraform/README.md

---

🔧 2. Configuration & Deployment (Ansible)

cd ansible
chmod +x generate_inventory.sh   # run once
./generate_inventory.sh

🔌 Test connection

ansible -i inventory.ini dev -m ping

🚀 Deploy application

ansible-playbook -i inventory.ini playbooks/noteapp.yml

👉 Full details: see ansible/README.md

---

🐳 3. Application (Docker Compose)

Once deployed via Ansible, services will be available:

Service	URL
Notes App	http://:8083
Prometheus	http://:9090
Grafana	http://:3000
cAdvisor	http://:8080
