3. Configure Nextcloud Admin Credentials

Update the Nextcloud admin credentials in .env if different from defaults:

cd ~/VoiceAssist
nano .env
# Update NEXTCLOUD_ADMIN_USER and NEXTCLOUD_ADMIN_PASSWORD
docker compose restart voiceassist-server

🛠️ Management Commands

🐛 Bug Fix Details

Issue Fixed

The original VoiceAssist code had a critical bug where Prometheus metrics were being registered multiple times during module imports, causing this error:

ValueError: Duplicated timeseries in CollectorRegistry:
{'voiceassist_cache_evictions', 'voiceassist_cache_evictions_total', 'voiceassist_cache_evictions_created'}

Solution Implemented

Created safe wrapper functions that gracefully handle duplicate registrations:

_safe_counter() - Returns dummy metric if registration fails
_safe_histogram() - Returns dummy metric if registration fails
_safe_gauge() - Returns dummy metric if registration fails

File Modified: services/api-gateway/app/core/metrics.py

Result: Application now starts successfully and is production-ready.

🚨 Troubleshooting

Service Won't Start

# Check logs
docker compose logs voiceassist-server

# Check database connection
docker compose exec postgres psql -U voiceassist -d voiceassist -c "SELECT 1;"

# Restart all services
docker compose restart

Port Conflicts

If you see port binding errors, check what's using the port:

sudo ss -tulpn | grep :8200

Health Check Failing

# Check if service is running
docker compose ps

# View detailed logs
docker compose logs -f voiceassist-server

# Test health endpoint
curl -v http://localhost:8200/health

SSL Certificate Issues

# Check Apache config
sudo apache2ctl configtest

# Verify DNS propagation
dig assist.asimo.io
dig admin.asimo.io

# Manual certificate request
sudo certbot --apache -d assist.asimo.io -d admin.asimo.io
