🦀 TuskLang Rust Production Checklist

"We don't bow to any king" - Rust Edition

Master the production deployment checklist for TuskLang Rust applications. From pre-deployment validation to post-deployment monitoring - ensure your applications are production-ready with maximum reliability, security, and performance.

🎯 What You've Learned

1. Pre-deployment checklist - Code quality, testing, security audit, configuration validation 2. Deployment checklist - Docker build validation, Kubernetes deployment validation 3. Post-deployment checklist - Health check validation, performance validation 4. Security validation - Container security scan, SSL/TLS validation, security headers 5. Monitoring setup - Prometheus metrics, Grafana dashboards, alerting rules 6. Incident response - Service down, performance degradation, security incidents, data loss 7. Complete production checklist - Comprehensive validation for production readiness

🚀 Next Steps

1. Automate the checklist - Integrate these checks into your CI/CD pipeline 2. Customize for your needs - Adapt the checklist to your specific requirements 3. Regular validation - Run these checks regularly in production 4. Continuous improvement - Update the checklist based on lessons learned 5. Team training - Ensure your team understands and follows the checklist
