🔍 Troubleshooting

Container won't start

docker compose config  # Validate config
docker compose logs app --tail=50  # Check errors

Port already in use

PORT=auto (default) automatically finds an available port. If you set a specific port that's taken:

# Check what's using the port
sudo netstat -tlnp | grep :3000

# Switch back to auto or choose a different port
# Edit .env: PORT=auto

Database connection failed

# Check database health
docker compose ps

# Verify environment variables loaded
docker compose exec app env | grep DATABASE

SSL certificate issues

# Check Caddy logs
docker compose logs caddy

# Test Caddy config
docker compose exec caddy caddy validate --config /etc/caddy/Caddyfile

Image pull fails

# Verify image exists
docker pull ghcr.io/cyph3rasi/synapsis:latest

# Check available tags at:
# https://github.com/cyph3rasi/synapsis/pkgs/container/synapsis

💾 Backup Strategy

Create /opt/synapsis/backup.sh:

#!/bin/bash
BACKUP_DIR="/var/backups/synapsis"
DATE=$(date +%Y%m%d_%H%M%S)
mkdir -p $BACKUP_DIR

# Database backup
docker compose exec -T postgres pg_dump -U synapsis synapsis > "$BACKUP_DIR/db_$DATE.sql"

echo "✅ Backup complete: $DATE"

Schedule daily backups:

chmod +x /opt/synapsis/backup.sh
echo "0 2 * * * /opt/synapsis/backup.sh" | sudo crontab -
