## =====================================
## 🚨 TROUBLESHOOTING
## =====================================

# Service won't start - check logs
docker-compose logs [service] --tail 50

# Fix: Restart service
docker-compose restart [service]

# Port already in use
# Change port in docker-compose.yml or:
sudo lsof -i :5555
sudo kill -9 PID

# Database won't connect
docker-compose exec postgres psql -U bot -d tg_autoposter -c "\dt"

# Fix: Run migrations
docker-compose exec bot alembic upgrade head

# Out of disk space
docker system prune -a
docker image prune
docker volume prune

# Memory issues
docker stats
docker-compose restart [service]

# Permission denied
sudo chown -R $USER:$USER .
chmod +x docker.sh quickstart.sh

## =====================================
## 🔐 SECURITY
## =====================================

# Generate secure password
openssl rand -base64 32

# Check for exposed secrets
git log --all --oneline --grep="password\|secret\|key" | head -20

# Scan for security issues
pip install bandit
docker-compose exec bot bandit -r app/

# Check for vulnerable dependencies
pip install safety
docker-compose exec bot safety check

# Rotate secrets
# 1. Generate new values
# 2. Update .env and secrets
# 3. Restart services
docker-compose restart

## =====================================
## 📈 PERFORMANCE TUNING
## =====================================

# Check slow queries (in PostgreSQL)
# Enable slow query log, then:
docker-compose exec postgres tail -f /var/log/postgresql/slowquery.log

# Check database size
docker-compose exec postgres psql -U bot -d tg_autoposter -c "
  SELECT schemaname, tablename, 
         pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename))
  FROM pg_tables 
  ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC;"

# Analyze query performance
docker-compose exec postgres psql -U bot -d tg_autoposter -c "EXPLAIN ANALYZE SELECT * FROM messages LIMIT 10;"

# Vacuum and analyze database
docker-compose exec postgres psql -U bot -d tg_autoposter -c "VACUUM ANALYZE;"

## =====================================
## 🔄 COMMON WORKFLOWS
## =====================================

# Full restart (nuclear option)
docker-compose down -v
docker-compose up -d
docker-compose exec bot alembic upgrade head

# Backup and cleanup
docker-compose exec -T postgres pg_dump -U bot tg_autoposter > backup.sql
docker-compose down -v
docker image prune -a
docker volume prune

# Deploy new version
git pull origin main
docker-compose build
docker-compose up -d
docker-compose exec bot alembic upgrade head
docker-compose logs -f

# Roll back to previous version
git checkout previous-tag
docker-compose build
docker-compose up -d
docker-compose exec bot alembic downgrade -1

## =====================================
## 💡 QUICK TIPS
## =====================================

# Use alias for faster commands (add to ~/.bashrc)
# alias dc='docker-compose'
# alias dcb='docker-compose build'
# alias dcd='docker-compose down'
# alias dcu='docker-compose up -d'
# alias dcl='docker-compose logs -f'
# alias dcp='docker-compose ps'

# Then use:
# dc ps
# dcl bot
# dcu

# Use Make for predefined targets
make help      # Show all make targets
make up        # Start services
make down      # Stop services
make logs      # View logs

# Use docker.sh for comprehensive management
./docker.sh up
./docker.sh logs
./docker.sh ps
