Deployment Guide

Instructions for deploying VoiceAssist to production and staging environments, including server configuration and service management.

Production

  • • quran.asimo.io - Voice Mode Web App
  • • kb.asimo.io - Admin Control Panel
  • • docs.asimo.io - Documentation Hub

Services

  • • quran-rtc.service - FastAPI backend
  • • quran-ingest.service - KB ingestion
  • • Apache2 - Reverse proxy

Quick Commands

sudo systemctl status quran-rtc
sudo systemctl restart quran-rtc
sudo journalctl -u quran-rtc -f
Rolling-safe
Release checklist
  • Validate quran-rtc and quran-ingest service health in staging.
  • Confirm Control Panel authentication works after migrations.
  • Flip CDN cache rules only after the WebSocket edge routes are green.

Deployment pipeline

Zero downtime guardrails

Deployments keep a warm pool of workers and reload the Apache proxy last, so existing WebSocket sessions finish streaming before connections drain.

Environment-specific commands

  • ssh staging sudo systemctl restart quran-rtc
  • ssh staging sudo journalctl -u quran-rtc -f
  • ssh staging sudo systemctl status quran-ingest
Troubleshooting shortcuts
  • Use sudo lsof -i :8000 if sockets appear stuck after a deploy.
  • Snapshot /var/log/apache2/error.log before restarting to keep history when reproducing regressions.

API Backend (localhost:8000 or api.asimo.io)
   ↓ REST/WebSocket
Services (PostgreSQL, Redis, Qdrant)

API Endpoints Used:

  • POST /api/auth/login - Authentication
  • GET /api/auth/me - Session validation
  • GET /api/admin/panel/summary - Dashboard metrics
  • GET /api/users - User listing
  • PATCH /api/users/:id - User updates
  • GET /api/admin/kb/documents - KB documents
  • POST /api/admin/kb/documents - Upload documents

Security Configuration

SSL/TLS

  • Protocol: TLS 1.2+
  • Certificate: Let's Encrypt (trusted CA)
  • Auto-renewal: Configured via certbot
  • HSTS: Not currently enabled (recommended for future)

Security Headers

  1. X-Content-Type-Options: nosniff

    • Prevents MIME type sniffing
  2. X-Frame-Options: SAMEORIGIN

    • Prevents clickjacking
  3. X-XSS-Protection: 1; mode=block

    • Enables XSS filtering
  4. Referrer-Policy: strict-origin-when-cross-origin

    • Controls referrer information
  5. Content-Security-Policy: Restrictive policy

    • default-src 'self'
    • script-src 'self' 'unsafe-inline' 'unsafe-eval'
    • connect-src 'self' http://localhost:8000 https://api.asimo.io

CORS Configuration

  • Access-Control-Allow-Origin: *
  • Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS, PATCH
  • Access-Control-Allow-Headers: Content-Type, Authorization

Note: In production, consider restricting CORS to specific origins.

Authentication

  • Method: JWT tokens
  • Storage: localStorage (client-side)
  • Validation: Server-side on every request
  • Admin-only: All routes require admin role

Maintenance

Updating the Admin Panel

  1. Make changes in ~/VoiceAssist/apps/admin-panel/src/

  2. Build:

    cd ~/VoiceAssist/apps/admin-panel npm run build
  3. Deploy:

    sudo cp -r dist/* /var/www/admin.asimo.io/ sudo chown -R www-data:www-data /var/www/admin.asimo.io
  4. Clear browser cache (Ctrl+Shift+R)

Monitoring

Apache Logs:

# Error log sudo tail -f /var/log/apache2/admin-voiceassist-error.log # Access log sudo tail -f /var/log/apache2/admin-voiceassist-access.log

Service Status:

# Apache status sudo systemctl status apache2 # Test configuration sudo apache2ctl configtest # List virtual hosts sudo apache2ctl -S | grep admin

Troubleshooting

Problem: 404 errors on page refresh Solution: Verify SPA rewrite rules in Apache config

Problem: API calls failing (CORS errors) Solution: Check CSP connect-src includes API URL

Problem: Login not working Solution: Verify backend API is running on localhost:8000

Problem: SSL certificate expired Solution: Renew via certbot: sudo certbot renew


Performance

Load Time

  • HTML: < 1 KB (instant)
  • CSS: 0.12 KB (instant)
  • JS Bundle: 202 KB (gzipped: 63.62 KB)
  • Total First Load: ~64 KB transferred

Optimization

  • ✅ Gzip compression enabled
  • ✅ Static assets cached by browser
  • ✅ Minified JS/CSS
  • ⚠️ Consider CDN for static assets (future)
  • ⚠️ Consider code splitting (future)

2. SSL/TLS Verification

# Test SSL certificate openssl s_client -servername your-domain.com -connect your-domain.com:443 # Check SSL Labs (optional) # Visit: https://www.ssllabs.com/ssltest/analyze.html?d=your-domain.com

3. Database Verification

# Connect to PostgreSQL docker-compose exec postgres psql -U voiceassist -d voiceassist # Run queries SELECT COUNT(*) FROM users; SELECT version(); \q

4. Monitoring Verification

# Access Grafana # URL: https://your-domain.com:3001 # Login: admin / <GRAFANA_ADMIN_PASSWORD> # Check dashboards: # - VoiceAssist Overview # - API Performance # - Database Performance # - System Resources

5. Functional Testing

# Register test user curl -X POST https://your-domain.com/api/auth/register \ -H "Content-Type: application/json" \ -d '{"email":"test@example.com","password":"TestPassword123!","full_name":"Test User"}' # Login curl -X POST https://your-domain.com/api/auth/login \ -H "Content-Type: application/json" \ -d '{"email":"test@example.com","password":"TestPassword123!"}' # Save the access_token from response # Test authenticated endpoint curl -H "Authorization: Bearer <access_token>" \ https://your-domain.com/api/auth/me

Rollback Procedures

Quick Rollback (Service Restart)

If the issue is with the current deployment but data is intact:

# 1. Stop services docker-compose -f docker-compose.yml \ -f deployment/production/configs/docker-compose.prod.yml \ down # 2. Checkout previous version git log --oneline # Find previous commit hash git checkout <previous-commit-hash> # 3. Rebuild and restart docker-compose -f docker-compose.yml \ -f deployment/production/configs/docker-compose.prod.yml \ up -d --build # 4. Verify rollback bash deployment/production/smoke-tests/smoke-test.sh --domain your-domain.com

Database Rollback (with Backup Restore)

If database changes need to be reverted:

# 1. Stop all services docker-compose down # 2. Restore database from backup cd /opt/voiceassist bash ha-dr/backup/restore.sh \ --file /opt/voiceassist/backups/voiceassist_backup_YYYYMMDD.sql.gz.gpg \ --passphrase "<GPG_PASSPHRASE>" # 3. Start services docker-compose -f docker-compose.yml \ -f deployment/production/configs/docker-compose.prod.yml \ up -d # 4. Verify data integrity docker-compose exec postgres psql -U voiceassist -d voiceassist -c "SELECT COUNT(*) FROM users;"

Troubleshooting

Common Issues

1. Service Won't Start

Symptoms: Container exits immediately or won't start

Diagnosis:

# Check container logs docker-compose logs voiceassist-server # Check container status docker-compose ps # Inspect container docker inspect voiceassist-server

Solutions:

  • Check .env file for missing/incorrect values
  • Verify ports are not in use: netstat -tulpn | grep <port>
  • Check disk space: df -h
  • Review logs for specific error messages

2. Database Connection Failed

Symptoms: "Cannot connect to database" errors

Diagnosis:

# Check PostgreSQL is running docker-compose ps postgres # Test connection docker-compose exec postgres pg_isready -U voiceassist # Check logs docker-compose logs postgres

Solutions:

  • Verify DATABASE_URL in .env
  • Check PostgreSQL container health
  • Verify credentials
  • Check network connectivity: docker network ls

3. SSL Certificate Issues

Symptoms: "Certificate error" or "Not secure" warnings

Diagnosis:

# Check certificate openssl s_client -servername your-domain.com -connect your-domain.com:443 # Check nginx config nginx -t # Check Let's Encrypt logs cat /var/log/letsencrypt/letsencrypt.log

Solutions:

  • Verify DNS points to correct IP
  • Re-run SSL setup script
  • Check firewall allows port 80 (for renewal)
  • Manually renew: certbot renew --force-renewal

4. High Memory Usage

Symptoms: System slow, OOM errors

Diagnosis:

# Check memory usage free -h docker stats # Check for memory leaks docker-compose top

Solutions:

  • Increase server memory
  • Adjust container memory limits in docker-compose.prod.yml
  • Restart services: docker-compose restart
  • Check for zombie processes

5. Slow API Response

Symptoms: High response times, timeouts

Diagnosis:

# Check response times curl -w "@curl-format.txt" -o /dev/null -s https://your-domain.com/health # Check database performance docker-compose exec postgres psql -U voiceassist -d voiceassist -c "SELECT * FROM pg_stat_activity;" # Check load uptime

Solutions:

  • Scale up workers in docker-compose.prod.yml
  • Optimize database queries
  • Add database indexes

🔧 Management Commands

Production Deployment Procedure

IMPORTANT: The correct deployment location is ~/VoiceAssist, NOT /opt/voiceassist. The production containers build from the project codebase at ~/VoiceAssist.

Standard Deployment (Schema/Code Changes)

# 1. Navigate to project directory cd ~/VoiceAssist # 2. Pull latest changes git pull origin main # 3. Rebuild the changed service docker-compose -f docker-compose.yml -f deployment/asimo-production/docker-compose.prod.yml build voiceassist-server # 4. Stop and remove the old container cd ~/VoiceAssist/deployment/asimo-production docker-compose stop voiceassist-server docker-compose rm -f voiceassist-server # 5. Start the updated container cd ~/VoiceAssist docker-compose -f docker-compose.yml -f deployment/asimo-production/docker-compose.prod.yml up -d voiceassist-server # 6. Verify health docker ps | grep voiceassist-server docker logs voiceassist-server --tail 50 curl https://assist.asimo.io/health

Quick Restart (No Code Changes)

# Using Docker Compose from project directory cd ~/VoiceAssist docker-compose restart voiceassist-server # Or restart all services docker-compose restart

Emergency Rollback

# 1. Checkout previous commit cd ~/VoiceAssist git log --oneline -10 # Find the commit to roll back to git checkout <commit-hash> # 2. Rebuild and redeploy docker-compose -f docker-compose.yml -f deployment/asimo-production/docker-compose.prod.yml build voiceassist-server docker-compose -f docker-compose.yml -f deployment/asimo-production/docker-compose.prod.yml up -d voiceassist-server # 3. Verify rollback curl https://assist.asimo.io/health

⚠️ NOTE: Avoid manual docker run commands for production deployments. Always use docker-compose to ensure proper network configuration, health checks, and restart policies.

Database Password Management

Important: PostgreSQL container passwords are set during initial database initialization and cannot be changed via environment variables alone.

If you need to reset the database password:

# 1. Connect to the postgres container docker exec -it voiceassist-postgres psql -U voiceassist -d voiceassist # 2. Run the ALTER USER command ALTER USER voiceassist WITH PASSWORD 'your_new_password_here'; # 3. Exit psql \q # 4. Update .env file to match # Edit ~/VoiceAssist/.env and update POSTGRES_PASSWORD # 5. Restart the API server to pick up new password docker-compose restart voiceassist-server

Verification:

# Test database connection from API server container docker exec voiceassist-server bash -c 'PGPASSWORD=$POSTGRES_PASSWORD psql -h postgres -U voiceassist -d voiceassist -c "SELECT 1;"' # Should return: 1

Common Issues:

  • FATAL: password authentication failed - Password mismatch between .env and database
  • Solution: Follow password reset procedure above to sync passwords

Service Management

# Using systemd (deprecated - use docker-compose instead) sudo systemctl status voiceassist sudo systemctl restart voiceassist sudo systemctl stop voiceassist sudo systemctl start voiceassist # Using Docker Compose (RECOMMENDED) cd ~/VoiceAssist docker-compose ps # Check status docker-compose logs -f # View logs docker-compose restart # Restart all docker-compose restart voiceassist-server # Restart specific service

Monitoring Stack

cd /opt/voiceassist sudo docker-compose -f deployment/asimo-production/docker-compose.monitoring.yml ps sudo docker-compose -f deployment/asimo-production/docker-compose.monitoring.yml logs -f sudo docker-compose -f deployment/asimo-production/docker-compose.monitoring.yml restart

Health Checks

# Manual health check script /opt/voiceassist/scripts/health-check.sh # Individual service checks curl https://assist.asimo.io/health curl http://localhost:8000/health curl http://localhost:9090/-/healthy curl http://localhost:3001/api/health

Logs

# Application logs sudo docker-compose logs -f voiceassist-server # Apache logs sudo tail -f /var/log/apache2/assist-error.log sudo tail -f /var/log/apache2/monitor-error.log # System logs sudo journalctl -u voiceassist -f sudo journalctl -u apache2 -f # Monitoring logs sudo docker logs voiceassist-prometheus -f sudo docker logs voiceassist-grafana -f

📝 Automated Tasks

Cron Jobs

Health Monitoring:

*/5 * * * * /opt/voiceassist/scripts/health-check.sh

Runs every 5 minutes to check service health and send alerts if needed.

Log Rotation

Configured via /etc/logrotate.d/voiceassist:

  • Apache logs: 14-day retention
  • Application logs: 30-day retention
  • Compressed after rotation

SSL Certificate Renewal

  • Managed by Certbot systemd timer
  • Automatic renewal before expiration
  • Check status: sudo systemctl status certbot.timer

🐛 Known Issues & Workarounds

1. cAdvisor Port Conflict

Issue: cAdvisor failed to start due to port 8080 already in use by Node process.

Impact: Low - Container metrics unavailable, but system metrics available via Node Exporter.

Status: Non-critical, monitoring still functional without cAdvisor.

Workaround (if needed):

# Find process using port 8080 sudo lsof -i :8080 # Either stop the conflicting process or change cAdvisor port in: # /opt/voiceassist/deployment/asimo-production/docker-compose.monitoring.yml

2. AlertManager Email Configuration ✅ RESOLVED

Issue: AlertManager was restarting due to SMTP configuration errors.

Resolution: Configured Hostinger SMTP with proper credentials:

  • SMTP Server: smtp.hostinger.com:587
  • Email: mo@asimo.io
  • TLS: Enabled
  • All alert notifications now sent to mo@asimo.io

Status: ✅ Resolved - Email alerts operational

3. Update docker-compose.yml for Production

Add resource limits, restart policies, and Traefik labels to the VoiceAssist docker-compose.yml. See phase documents for complete configuration.

4. Start VoiceAssist Stack

cd /opt/voiceassist-prod docker compose up -d # Check status docker compose ps # View logs docker compose logs -f

Deploy Traefik (Reverse Proxy)

Create a separate Traefik stack for SSL termination:

sudo mkdir -p /opt/traefik cd /opt/traefik # Create docker-compose.yml cat > docker-compose.yml <<'EOF' version: '3.8' networks: traefik-network: name: traefik-network driver: bridge volumes: traefik-certs: services: traefik: image: traefik:v2.10 restart: unless-stopped ports: - "80:80" - "443:443" volumes: - /var/run/docker.sock:/var/run/docker.sock:ro - traefik-certs:/letsencrypt - ./traefik.yml:/etc/traefik/traefik.yml:ro networks: - traefik-network labels: - "traefik.enable=true" - "traefik.http.routers.dashboard.rule=Host(`traefik.yourdomain.com`)" - "traefik.http.routers.dashboard.entrypoints=websecure" - "traefik.http.routers.dashboard.tls.certresolver=letsencrypt" - "traefik.http.routers.dashboard.service=api@internal" EOF # Create traefik.yml cat > traefik.yml <<'EOF' api: dashboard: true entryPoints: web: address: ":80" http: redirections: entryPoint: to: websecure scheme: https websecure: address: ":443" providers: docker: endpoint: "unix:///var/run/docker.sock" exposedByDefault: false network: traefik-network certificatesResolvers: letsencrypt: acme: email: admin@yourdomain.com storage: /letsencrypt/acme.json httpChallenge: entryPoint: web EOF # Start Traefik docker compose up -d

Kubernetes Production Deployment

Kubernetes Cluster Setup

# Install K3s curl -sfL https://get.k3s.io | sh - # Verify installation sudo k3s kubectl get nodes # Copy kubeconfig mkdir -p ~/.kube sudo cp /etc/rancher/k3s/k3s.yaml ~/.kube/config sudo chown $USER:$USER ~/.kube/config # Install kubectl sudo snap install kubectl --classic # Verify kubectl get nodes

Option 2: Kubeadm (Multi-node cluster)

# On all nodes: Install container runtime (containerd) sudo apt install -y containerd sudo mkdir -p /etc/containerd containerd config default | sudo tee /etc/containerd/config.toml sudo systemctl restart containerd # On all nodes: Install kubeadm, kubelet, kubectl curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg echo 'deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://pkgs.k8s.io/core:/stable:/v1.28/deb/ /' | sudo tee /etc/apt/sources.list.d/kubernetes.list sudo apt-get update sudo apt-get install -y kubelet kubeadm kubectl sudo apt-mark hold kubelet kubeadm kubectl # On master node: Initialize cluster sudo kubeadm init --pod-network-cidr=10.244.0.0/16 # Configure kubectl mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config # Install CNI (Calico) kubectl apply -f https://raw.githubusercontent.com/projectcalico/calico/v3.26.0/manifests/calico.yaml # On worker nodes: Join cluster (use token from kubeadm init output) sudo kubeadm join <master-ip>:6443 --token <token> --discovery-token-ca-cert-hash sha256:<hash>

Deploy to Kubernetes

See COMPOSE_TO_K8S_MIGRATION.md for detailed migration from Docker Compose to Kubernetes.

High-level steps:

  1. Create namespaces for nextcloud and voiceassist
  2. Convert docker-compose.yml to Kubernetes manifests (Deployments, Services, ConfigMaps, Secrets)
  3. Set up persistent storage (PersistentVolumeClaims)
  4. Configure Ingress with cert-manager for SSL
  5. Deploy observability stack (Prometheus, Grafana, Jaeger, Loki)
  6. Configure HorizontalPodAutoscaler for scaling
  7. Set up Network Policies for security

Network Configuration

DNS Configuration

# A Records
nextcloud.yourdomain.com    → <server-ip>
voiceassist.yourdomain.com  → <server-ip>
traefik.yourdomain.com      → <server-ip>
grafana.yourdomain.com      → <server-ip>
prometheus.yourdomain.com   → <server-ip>

Firewall Rules

# Allow HTTP/HTTPS sudo ufw allow 80/tcp sudo ufw allow 443/tcp # Allow SSH (change port if using non-standard) sudo ufw allow 22/tcp # Kubernetes (if using K8s) sudo ufw allow 6443/tcp # API server sudo ufw allow 2379:2380/tcp # etcd sudo ufw allow 10250/tcp # kubelet # Enable firewall sudo ufw enable

SSL/TLS Setup

Automatic SSL with Traefik + Let's Encrypt

Traefik automatically obtains and renews SSL certificates. Configuration already included in Traefik docker-compose.yml above.

Manual SSL Setup (Alternative)

# Install certbot sudo apt install -y certbot # Obtain certificates sudo certbot certonly --standalone -d nextcloud.yourdomain.com sudo certbot certonly --standalone -d voiceassist.yourdomain.com # Certificates stored in: # /etc/letsencrypt/live/nextcloud.yourdomain.com/ # /etc/letsencrypt/live/voiceassist.yourdomain.com/ # Auto-renewal (already configured by certbot) sudo systemctl status certbot.timer

Security Hardening

1. Enable Fail2Ban

sudo apt install -y fail2ban # Configure for SSH sudo cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local sudo vim /etc/fail2ban/jail.local # Enable SSH jail [sshd] enabled = true port = 22 maxretry = 3 bantime = 3600 sudo systemctl restart fail2ban

2. Disable Password Authentication

sudo vim /etc/ssh/sshd_config # Set: PasswordAuthentication no PubkeyAuthentication yes sudo systemctl restart ssh

3. Enable Automatic Security Updates

sudo apt install -y unattended-upgrades sudo dpkg-reconfigure --priority=low unattended-upgrades

4. Configure AppArmor

# Check AppArmor status sudo aa-status # Enable AppArmor profiles for Docker sudo apt install -y apparmor-profiles apparmor-utils

5. Network Policies (Kubernetes)

See phase documents for detailed NetworkPolicy configurations that enforce zero-trust networking.


Monitoring & Observability

Access Monitoring Services

After deployment:

Configure Alerting

Edit /opt/voiceassist-prod/infrastructure/prometheus/alerts.yml:

groups: - name: voiceassist_alerts interval: 30s rules: - alert: HighMemoryUsage expr: (node_memory_MemTotal_bytes - node_memory_MemAvailable_bytes) / node_memory_MemTotal_bytes > 0.9 for: 5m labels: severity: warning annotations: summary: "High memory usage on {{ $labels.instance }}" - alert: ServiceDown expr: up == 0 for: 2m labels: severity: critical annotations: summary: "Service {{ $labels.job }} is down"

Backup & Disaster Recovery

Automated Backup Script

sudo mkdir -p /opt/scripts sudo vim /opt/scripts/backup.sh
#!/bin/bash BACKUP_DIR="/opt/backups" DATE=$(date +%Y%m%d_%H%M%S) # Backup Nextcloud database docker exec nextcloud-prod-nextcloud-db-1 pg_dump -U nextcloud nextcloud | gzip > "$BACKUP_DIR/nextcloud_db_$DATE.sql.gz" # Backup Nextcloud data tar czf "$BACKUP_DIR/nextcloud_data_$DATE.tar.gz" /data/nextcloud/data # Backup VoiceAssist database docker exec voiceassist-prod-postgres-1 pg_dump -U voiceassist voiceassist | gzip > "$BACKUP_DIR/voiceassist_db_$DATE.sql.gz" # Backup Qdrant data tar czf "$BACKUP_DIR/qdrant_data_$DATE.tar.gz" /data/voiceassist/qdrant # Backup Redis data docker exec voiceassist-prod-redis-1 redis-cli --rdb /data/dump.rdb docker cp voiceassist-prod-redis-1:/data/dump.rdb "$BACKUP_DIR/redis_$DATE.rdb" # Delete backups older than 30 days find "$BACKUP_DIR" -type f -mtime +30 -delete # Upload to S3 (optional) # aws s3 sync "$BACKUP_DIR" s3://your-bucket/voiceassist-backups/ echo "Backup completed: $DATE"
sudo chmod +x /opt/scripts/backup.sh # Add to crontab (daily at 2 AM) (crontab -l 2>/dev/null; echo "0 2 * * * /opt/scripts/backup.sh") | crontab -

Restore Procedure

# Restore Nextcloud DB gunzip < /opt/backups/nextcloud_db_20241119.sql.gz | docker exec -i nextcloud-prod-nextcloud-db-1 psql -U nextcloud -d nextcloud # Restore Nextcloud data cd /data/nextcloud sudo rm -rf data sudo tar xzf /opt/backups/nextcloud_data_20241119.tar.gz sudo chown -R 33:33 data # www-data user in container # Restore VoiceAssist DB gunzip < /opt/backups/voiceassist_db_20241119.sql.gz | docker exec -i voiceassist-prod-postgres-1 psql -U voiceassist -d voiceassist # Restart services cd /opt/nextcloud-prod && docker compose restart cd /opt/voiceassist-prod && docker compose restart

Maintenance Procedures

Update Docker Images

# Pull latest images cd /opt/nextcloud-prod docker compose pull cd /opt/voiceassist-prod docker compose pull # Recreate containers docker compose up -d # Remove old images docker image prune -af

View Logs

# Nextcloud logs cd /opt/nextcloud-prod docker compose logs -f nextcloud # VoiceAssist logs cd /opt/voiceassist-prod docker compose logs -f api-gateway # All services docker compose logs -f # Last 100 lines docker compose logs --tail=100

Database Maintenance

# Vacuum PostgreSQL (Nextcloud) docker exec nextcloud-prod-nextcloud-db-1 vacuumdb -U nextcloud -d nextcloud --analyze # Vacuum PostgreSQL (VoiceAssist) docker exec voiceassist-prod-postgres-1 vacuumdb -U voiceassist -d voiceassist --analyze # Redis info docker exec voiceassist-prod-redis-1 redis-cli info

Disk Space Management

# Check disk usage df -h # Docker disk usage docker system df # Clean up unused Docker resources docker system prune -af --volumes # Check specific directory sizes du -sh /data/* du -sh /opt/* du -sh /opt/backups/*

Troubleshooting

Service Won't Start

# Check service status docker compose ps # View logs docker compose logs <service-name> # Check resource usage docker stats # Check for port conflicts sudo netstat -tulpn | grep <port>

Database Connection Issues

# Test database connectivity docker exec voiceassist-prod-postgres-1 pg_isready -U voiceassist # Check database logs docker logs voiceassist-prod-postgres-1 # Restart database docker compose restart postgres

SSL Certificate Issues

# Check certificate expiration echo | openssl s_client -servername voiceassist.yourdomain.com -connect voiceassist.yourdomain.com:443 2>/dev/null | openssl x509 -noout -dates # Force certificate renewal (Traefik) docker exec traefik cat /letsencrypt/acme.json # Restart Traefik cd /opt/traefik docker compose restart

Performance Issues

# Check system resources htop free -h df -h # Check Docker stats docker stats # Review Grafana dashboards # https://grafana.yourdomain.com # Check slow queries (PostgreSQL) docker exec voiceassist-prod-postgres-1 psql -U voiceassist -d voiceassist -c "SELECT * FROM pg_stat_statements ORDER BY total_exec_time DESC LIMIT 10;"

Migration Between Environments

From Docker Compose to Kubernetes

See COMPOSE_TO_K8S_MIGRATION.md for comprehensive guide.

From Development to Production

# On MacBook: Export images cd ~/VoiceAssist docker compose build docker save $(docker compose images -q) | gzip > voiceassist-prod.tar.gz # Copy to server scp voiceassist-prod.tar.gz deploy@server:/opt/voiceassist-prod/ # On server: Load and start cd /opt/voiceassist-prod docker load < voiceassist-prod.tar.gz docker compose up -d

Next Steps
