🚀 Deployment Workflow¶
Step-by-Step¶
1. Local Development
└─> README_REDIS.md → Quick Start
└─> Run: docker run -d -p 6379:6379 redis:7-alpine
└─> Configure: .env (use .env.redis.example)
└─> Test: python slack_bot.py
2. Performance Validation
└─> Run: python benchmark_session_performance.py
└─> Verify: 50-80x improvement
3. Integration Testing
└─> Test: Slack bot functionality
└─> Verify: Sessions persist, TTL works
4. Pre-Deployment Checklist
└─> Complete: REDIS_VALIDATION_CHECKLIST.md
5. Production Deployment
└─> Follow: docs/REDIS_SETUP.md → Production Deployment
└─> Create: Memorystore instance
└─> Configure: VPC connector
└─> Deploy: Cloud Run
6. Post-Deployment Monitoring
└─> Check: Response times
└─> Verify: No errors
└─> Monitor: 24h
7. Rollback Plan (if needed)
└─> Follow: REDIS_ROLLBACK_GUIDE.md
🔍 Quick Reference¶
Environment Variables¶
# Backend selection
SESSION_BACKEND=redis # redis | cloudsql | inmemory
MEMORY_BACKEND=cloudsql # redis | cloudsql | inmemory
# Redis config
REDIS_URL=redis://host:6379/0
REDIS_SESSION_TTL=3600 # Seconds
# CloudSQL config (for memory)
CLOUDSQL_HOST=127.0.0.1
CLOUDSQL_PORT=3306
CLOUDSQL_DATABASE=ifriend_agent_db
CLOUDSQL_USER=user
CLOUDSQL_PASSWORD=password
Common Commands¶
# Start Redis locally
docker run -d -p 6379:6379 redis:7-alpine
# Test connection
redis-cli ping
# Run bot
python slack_bot.py
# Benchmark
python benchmark_session_performance.py
# Monitor Redis
redis-cli MONITOR
# Check sessions
redis-cli KEYS "session:*"
Emergency Rollback¶
# Fastest: Change env var
SESSION_BACKEND=cloudsql python slack_bot.py
# Production
gcloud run services update ifriend-slack-bot \
--set-env-vars=SESSION_BACKEND=cloudsql
📞 Support¶
Issues?¶
- Check: REDIS_ROLLBACK_GUIDE.md → Troubleshooting
- Test: Connection with
redis-cli ping - Fallback:
SESSION_BACKEND=inmemory(temporary) - Logs:
python slack_bot.py 2>&1 | grep -i redis
Performance Issues?¶
- Run:
python benchmark_session_performance.py - Verify: Backend in use (logs should show "Session Backend: redis")
- Check: Redis latency with
redis-cli --latency
Production Issues?¶
- Immediate: Update env var to
SESSION_BACKEND=cloudsql - Investigate: Check Memorystore status
- Rollback: Follow REDIS_ROLLBACK_GUIDE.md
🎯 Success Criteria¶
- ✅ append_event() < 10ms average
- ✅ Total response < 1s
- ✅ 50-80x speedup vs CloudSQL
- ✅ Session persistence works
- ✅ TTL cleanup automatic
- ✅ No errors in production
