🚨 Problem Statement

Modern application deployment involves multiple steps and tools. Managing them manually is time-consuming, error-prone, and overwhelming — especially for developers new to DevOps.

❌ Pain Point	😩 Impact
Manual Docker container setup	Time wasted on repetitive config
Complex server configuration	High chance of human error
No centralized deployment management	Scattered tools, no visibility
Difficult CI/CD pipeline setup	Slow release cycles

---

💡 Solution

DockStack provides a centralized DevOps platform that integrates all these tools into one seamless workflow.

✅  Manage projects from a unified dashboard
✅  Deploy applications using Docker containers
✅  Route traffic with Nginx reverse proxy
✅  Provision cloud infrastructure with Terraform
✅  Configure servers automatically with Ansible
✅  Automate every deployment with GitHub Actions

⚙️ Installation & Setup

Prerequisites

Make sure these are installed before you begin.

1️⃣ Clone the Repository

git clone https://github.com/YOUR_USERNAME/DockStack.git
cd DockStack

2️⃣ Backend Setup

cd backend
npm install
npm run dev

🟢 Backend API running at http://localhost:5000

3️⃣ Frontend Setup

cd frontend
npm install
npm run dev

⚛️ Frontend running at http://localhost:3000

---

🐳 Docker Setup

Run the entire platform — Frontend, Backend, MongoDB, and Nginx — with a single command.

docker-compose -f docker/docker-compose.yml up --build

Container	Service	Port
🔀 nginx	Reverse Proxy	80
⚛️ frontend	React App	3000
🟢 backend	Express API	5000
🍃 mongo	MongoDB	27017

🌐 Open http://localhost in your browser — Nginx routes everything automatically.

---

☁️ Infrastructure Setup (Terraform)

Provisions a cloud server ready for Docker deployments.

# Move into terraform directory
cd terraform

# Initialize Terraform providers
terraform init

# Preview what will be created
terraform plan

# Provision the server
terraform apply

✅  Apply complete!
✅  Resources: 2 added, 0 changed, 0 destroyed.
✅  Output: server_ip = "xx.xx.xx.xx"

🤖 Server Configuration (Ansible)

Automatically installs and configures Docker on your remote server.

ansible-playbook ansible/setup.yml

# What setup.yml does:
  ✔  Install Docker & Docker Compose
  ✔  Install Git
  ✔  Configure firewall (UFW)
  ✔  Enable Docker service on boot

---

🔄 CI/CD Pipeline

Push to main → app is live. Zero manual steps.

🔐 Authentication

JWT-based authentication secures all protected routes.

POST /api/auth/register   →  Create a new account
POST /api/auth/login      →  Login & receive JWT token
GET  /api/projects        →  🔒 Protected (token required)
GET  /api/deployments     →  🔒 Protected (token required)

Client ──── POST /login ────▶ Server
             ◀── JWT Token ────
Client ──── Authorization: Bearer <token> ──▶ Protected Routes
