WireFlow VPN - Quick Start Guide

🚀 Project Overview

WireFlow is a comprehensive end-to-end VPN solution built with modern DevOps practices. The project includes:

Tagline: "Seamless Secure Connections"

  • WireGuard VPN Server with high availability and load balancing
  • Management API for client and server administration
  • Kubernetes Deployment with auto-scaling and monitoring
  • Infrastructure as Code supporting AWS, GCP, and Azure
  • CI/CD Pipeline with security scanning and automated testing
  • Monitoring Stack with Prometheus, Grafana, and ELK
  • Security Hardening with network policies and compliance

📋 Prerequisites

Required Software

  • Docker 20.10+
  • Docker Compose 2.0+
  • kubectl 1.24+
  • terraform 1.0+
  • Git

Cloud Provider (Choose One)

  • AWS Account with EKS access
  • GCP Account with GKE access
  • Azure Account with AKS access

🏃‍♂️ Quick Start (5 Minutes)

1. Clone and Setup

git clone https://github.com/wireflow/vpn.git
cd vpn
chmod +x scripts/setup.sh
./scripts/setup.sh

2. Access Services

3. Add Your First VPN Client

# Add a client
docker exec vpn-wireguard /scripts/add-client.sh myclient

# Get client configuration
docker exec vpn-wireguard cat /etc/wireguard/keys/client_myclient.conf

4. Test VPN Connection

  1. Install WireGuard on your device
  2. Import the client configuration
  3. Connect to the VPN
  4. Verify your IP has changed

🏗️ Production Deployment

Option 1: Kubernetes (Recommended)

# Deploy to Kubernetes
chmod +x scripts/deploy-k8s.sh
./scripts/deploy-k8s.sh

# Check deployment
kubectl get pods -n wireflow-system
kubectl get services -n wireflow-system

Option 2: Cloud Infrastructure

# Deploy infrastructure
cd infrastructure
terraform init
terraform plan -var="environment=prod"
terraform apply

# Deploy applications
kubectl apply -f k8s/

🔧 Configuration

Environment Variables

Create a .env file:

# VPN Configuration
WG_HOST=your-domain.com
WG_PORT=51820
WG_DEFAULT_ADDRESS=10.0.0.1
WG_DEFAULT_DNS=8.8.8.8

# API Configuration
JWT_SECRET=your-secret-key
DATABASE_URL=sqlite:///app/vpn.db
REDIS_URL=redis://redis:6379

# Monitoring
PROMETHEUS_RETENTION=200h
GRAFANA_ADMIN_PASSWORD=secure-password

Custom Configuration

  • WireGuard: Edit docker/wireguard/scripts/start.sh
  • API: Modify src/api/app.py
  • Monitoring: Update monitoring/prometheus/prometheus.yml
  • Infrastructure: Customize infrastructure/ modules

📊 Monitoring and Management

Dashboards

  • VPN Performance: Grafana dashboard showing connections, traffic, and performance
  • System Resources: CPU, memory, disk, and network utilization
  • Security Events: Failed logins, suspicious activity, and alerts
  • Business Metrics: User growth, usage patterns, and trends

Alerts

  • VPN server down
  • High connection count
  • Unusual traffic patterns
  • System resource issues
  • Security incidents

Logs

  • Application Logs: API requests, errors, and performance
  • System Logs: WireGuard, kernel, and infrastructure logs
  • Security Logs: Authentication, authorization, and audit events
  • Access Logs: User activities and administrative actions

🔒 Security Features

Network Security

  • WireGuard encryption (ChaCha20)
  • Network segmentation and policies
  • Firewall rules and access controls
  • DDoS protection and rate limiting

Application Security

  • JWT authentication and authorization
  • Input validation and sanitization

🚀 CI/CD Pipeline

Automated Workflows

  • Code Quality: Linting, formatting, and type checking
  • Security Scanning: Vulnerability and dependency scanning
  • Testing: Unit, integration, and end-to-end tests
  • Deployment: Automated staging and production deployments

Quality Gates

  • All tests must pass
  • No high/critical security vulnerabilities
  • Code coverage > 90%
  • Performance benchmarks met

Deployment Strategies

  • Blue-Green: Zero-downtime deployments
  • Canary: Gradual rollout with monitoring
  • Rollback: Quick recovery from failed deployments
