Enterprise Traefik Deployment Solution

Overview

Complete production-ready Traefik deployment with authentication, monitoring, security hardening, and SELinux compliance for Docker Swarm environments.

Current Status: 🟡 PARTIALLY DEPLOYED (60% Complete)

• ✅ Core infrastructure working
• ✅ SELinux policy installed
• ⚠️ Docker socket access needs resolution
• ❌ Monitoring stack not deployed

🚀 Quick Start

Current Deployment Status

# Check current Traefik status
docker service ls | grep traefik

# View current logs
docker service logs traefik_traefik --tail 10

# Test basic connectivity
curl -I http://localhost:8080/ping

Next Steps (Priority Order)

# 1. Fix Docker socket access (CRITICAL)
sudo chmod 666 /var/run/docker.sock

# 2. Deploy monitoring stack
docker stack deploy -c stacks/monitoring/traefik-monitoring.yml monitoring

# 3. Migrate to production config
docker stack rm traefik
docker stack deploy -c stacks/core/traefik-production.yml traefik

One-Command Deployment (When Ready)

# Set your domain and email
export DOMAIN=yourdomain.com
export EMAIL=admin@yourdomain.com

# Deploy everything
./scripts/deploy-traefik-production.sh

Manual Step-by-Step

# 1. Install SELinux policy (✅ COMPLETED)
cd selinux && ./install_selinux_policy.sh

# 2. Deploy Traefik (✅ COMPLETED - needs socket fix)
docker stack deploy -c stacks/core/traefik.yml traefik

# 3. Deploy monitoring (❌ PENDING)
docker stack deploy -c stacks/monitoring/traefik-monitoring.yml monitoring

🔧 Components Status

Core Services

• Traefik v2.10: ✅ Running (needs socket fix for full functionality)
• Prometheus: ❌ Configured but not deployed
• Grafana: ❌ Configured but not deployed
• AlertManager: ❌ Configured but not deployed
• Loki + Promtail: ❌ Configured but not deployed

Security Features

• ✅ Authentication: bcrypt-hashed basic auth configured
• ⚠️ TLS/SSL: Configuration ready, not active
• ✅ Security Headers: Middleware configured
• ⚠️ Rate Limiting: Configuration ready, not active
• ✅ SELinux Policy: Custom module installed and active
• ⚠️ Access Control: Partially configured

Monitoring & Alerting

• ❌ Authentication Attacks: Detection configured, not deployed
• ❌ Performance Metrics: Rules defined, not active
• ❌ Certificate Monitoring: Alerts configured, not deployed
• ❌ Resource Monitoring: Dashboards ready, not deployed
• ❌ Smart Alerting: Rules defined, not active

🔐 Security Implementation

Authentication System

# Strong bcrypt authentication (work factor 10) - ✅ CONFIGURED
traefik.http.middlewares.dashboard-auth.basicauth.users=admin:$2y$10$xvzBkbKKvRX...

# Applied to all sensitive endpoints - ✅ READY
- dashboard (Traefik API/UI)
- prometheus (metrics)  
- alertmanager (alert management)

SELinux Integration - ✅ COMPLETED

The custom SELinux policy (traefik_docker.te) allows containers to access Docker socket while maintaining security:

# Allow containers to write to Docker socket
allow container_t container_var_run_t:sock_file { write read };
allow container_t container_file_t:sock_file { write read };

# Allow containers to connect to Docker daemon  
allow container_t container_runtime_t:unix_stream_socket connectto;

TLS Configuration - ⚠️ READY BUT NOT ACTIVE

• Protocols: TLS 1.2+ only
• Cipher Suites: Strong ciphers with Perfect Forward Secrecy
• HSTS: 2-year max-age with includeSubDomains
• Certificate Management: Automated Let's Encrypt with monitoring

📊 Monitoring Dashboard - ❌ NOT DEPLOYED

Key Metrics Tracked (Ready for Deployment)

1. Authentication Security

   • Failed login attempts per minute
   • Brute force attack detection
   • Geographic login analysis

2. Service Performance

   • 95th percentile response times
   • Error rate percentage
   • Service availability status

3. Infrastructure Health

   • Certificate expiration dates
   • Docker socket connectivity
   • Resource utilization trends

Alert Examples (Ready for Deployment)

# Critical: Possible brute force attack
rate(traefik_service_requests_total{code="401"}[1m]) > 50

# Warning: High authentication failure rate  
rate(traefik_service_requests_total{code=~"401|403"}[5m]) > 10

# Critical: TLS certificate expired
traefik_tls_certs_not_after - time() <= 0

🔄 Operational Procedures

Current Daily Operations

# Check service health
docker service ls | grep traefik

# Review authentication logs  
docker service logs traefik_traefik | grep -E "(401|403)"

# Check SELinux policy status
sudo semodule -l | grep traefik

Maintenance Tasks (When Fully Deployed)

# Update Traefik version
docker service update --image traefik:v3.2 traefik_traefik

# Rotate logs
sudo logrotate -f /etc/logrotate.d/traefik

# Backup configuration
tar -czf traefik-backup-$(date +%Y%m%d).tar.gz /opt/traefik/ /opt/monitoring/

🚨 Current Issues & Resolution

Priority 1: Docker Socket Access

Issue: Traefik cannot access Docker socket for service discovery Impact: Authentication and routing not fully functional Solution:

# Quick fix
sudo chmod 666 /var/run/docker.sock

# Or enable Docker API on TCP
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<EOF
{
  "hosts": ["unix:///var/run/docker.sock", "tcp://0.0.0.0:2375"]
}
EOF
sudo systemctl restart docker

Priority 2: Deploy Monitoring

Status: Configuration ready, deployment pending Action:

docker stack deploy -c stacks/monitoring/traefik-monitoring.yml monitoring

Priority 3: Migrate to Production

Status: Production config ready, migration pending Action:

docker stack rm traefik
docker stack deploy -c stacks/core/traefik-production.yml traefik
