📋 Prerequisites

• Docker & Docker Compose
• Make (optional, for using Makefile commands)

🛠️ Quick Start

1. Clone the Repository

git clone https://github.com/DOCNET-HQ/docnet_backend.git
cd docnet_backend

2. Environment Setup

Create a .env file in the project root:

cp .env.sample .env

3. Build and Run

Using Makefile (recommended):

# Build Docker images
make build

# Start all services
make up

# View logs
make logs

Or using Docker Compose directly:

# Build images
docker-compose -f docker/docker-compose.yml build

# Start services
docker-compose -f docker/docker-compose.yml up -d

# View logs
docker-compose -f docker/docker-compose.yml logs -f

4. Access the Application

• Django App: http://localhost:8000
• Flower (Celery Monitor): http://localhost:5555
• Health Check: http://localhost:8000/health/

🐳 Services

• Django Application (app)

• Celery Worker (celery)

• Celery Beat (celery-beat)

• Flower (flower)

• Redis (redis)

• PostgreSQL (db)

Running Tests

# Using Make
make test

# Using Docker Compose
docker-compose -f docker/docker-compose.yml exec app python manage.py test

Accessing Logs

# All services
make logs

# Specific service
docker-compose -f docker/docker-compose.yml logs -f app
docker-compose -f docker/docker-compose.yml logs -f celery

📊 Monitoring

Health Checks

• Django: http://localhost:8000/health/
• Redis: Built-in Redis ping
• PostgreSQL: Connection test every 5 seconds

Flower Dashboard

Access http://localhost:5555 using username: admin, password: admin to monitor:

• Active tasks
• Task history
• Worker status
• Task statistics

NOTE: You change the flower auth credentials in the docker/docker-compose.dev.yml file

🚀 Production Deployment

2. Static Files: Run make collectstatic
3. Database: Run migrations with make migrate
4. SSL/TLS: Configure reverse proxy (Nginx) for HTTPS
5. Monitoring: Set up proper logging and monitoring solutions
