🧪 Testing & Validation

🤖 Automated Demo Testing

# 🎯 Full deployment and validation
./demo-stack.sh deploy && ./demo-test.sh full

# 🔍 Security compliance validation
./demo-test.sh security

# 👤 File ownership validation
./demo-test.sh permissions

# 🌐 Network isolation validation
./demo-test.sh network

✅ Manual Validation Commands

# 📊 Check service status with dynamic naming
docker compose ps

# 📋 View service logs
docker compose logs {service-name}

# 🌐 Test individual endpoints with variables
curl -f http://localhost:${HOMEPAGE_PORT}/
curl -f http://localhost:${INFLUXDB_PORT}/ping
curl -f http://localhost:${GRAFANA_PORT}/api/health

# 🔍 Validate user permissions
ls -la /var/lib/docker/volumes/${COMPOSE_PROJECT_NAME}_*/

---

🔍 Troubleshooting

🚨 Common Issues

Services not starting

# 🔧 Check Docker daemon
docker info

# 🌐 Check network
docker network ls | grep tsysdevstack_supportstack

# 🔄 Recreate network
docker network create tsysdevstack_supportstack

Port conflicts

# 🔍 Check port usage
netstat -tulpn | grep :400

# 🗑️ Kill conflicting processes
sudo fuser -k {port}/tcp

Health check failures

# 🔍 Check individual service health
docker compose exec {service} curl -f http://localhost:{internal-port}/health

# 🔄 Restart specific service
docker compose restart {service}

🛠️ Service-Specific Issues

Issue	Service	Solution
DNS issues	Pi-hole	Ensure Docker DNS settings allow custom DNS servers Check that port 53 is available on the host
Database connection	Grafana-InfluxDB	Verify both services are on the same network Check database connectivity: curl http://localhost:4008/ping
Container access	Portainer	Ensure container socket is properly mounted Check Container Socket Proxy service if used

Data Persistence	❌ Disabled (demo mode)
Storage Type	Docker volumes (temporary)
Data Reset	✅ Automatic on restart
Credentials	🔒 Hardcoded demo only

🗂️ Volume Management

# 📋 List volumes

🚨 Security Notes

⚠️ Demo Configuration Only - Production Use Prohibited

🔒 Demo Security Model

• 🔓 Demo Credentials: Hardcoded for demonstration only
• 🚫 No Hardening: No encryption or security features
• 🌐 Network Isolation: Do not expose to external networks
• 🔄 Ephemeral Data: All data resets on container restart
• 📡 Docker Socket Proxy: Mandatory for all container operations

🛡️ Security Requirements

• Dynamic User Detection: Prevents root file ownership issues
• Docker Group Access: Required for socket proxy functionality
• Volume-First Storage: Docker volumes preferred over bind mounts
• Read-Only Host Access: Minimal host filesystem interaction
• Network Segregation: Services isolated in demo network

⚠️ Production Migration Warning

• Reset all credentials before production deployment
• Implement persistent data storage
• Add encryption and security hardening
• Configure proper backup and recovery
• Set up monitoring and alerting
