From 1891ea8e0a4ea77d3006b764a26cb391cf5107b1 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 6 Nov 2025 05:03:34 +0000 Subject: [PATCH] fix: Complete PR #261 - Production-ready K8s/OpenShift deployment fixes This commit addresses all critical and high-priority issues identified in PR #261 review comments for production-ready Kubernetes/OpenShift deployment. ## Critical Fixes (Must Fix) 1. **Remove hardcoded secrets from values.yaml** - Replaced all "changeme" placeholders with comprehensive documentation - Added guidance for 3 secure secret management methods: * Helm --set-string flags (CI/CD) * External secrets management (Vault, AWS Secrets Manager, etc.) * Kubernetes secret creation (dev only) - Documented all required and optional secret keys 2. **Add /health/ready endpoint** - Created new lightweight readiness probe endpoint at /api/health/ready - Optimized for fast response (checks only critical DB connection) - Separates readiness from comprehensive health checks - Prevents premature traffic routing to unhealthy pods 3. **Standardize health probe endpoints** - Fixed K8s deployment: /api/health and /api/health/ready - Fixed Helm deployment: /api/health and /api/health/ready - Added startup probe to Helm backend deployment - Standardized timing and failure thresholds across both deployments 4. **Fix page number return type handling** - Added try-except blocks to handle None values gracefully - Prevents TypeError when converting invalid page numbers to int - Added logging for debugging invalid page_no/page values ## High-Priority Enhancements 5. **Use immutable image tags** - Removed :latest tags from backend, frontend, and minio images - Updated values.yaml to require explicit version tags - Added documentation and examples for git SHA-based tagging - Changed pullPolicy to IfNotPresent for better performance 6. **Add resource quotas** - Created ResourceQuota manifests (K8s and Helm) - Set namespace-level limits: 20 CPU requests, 40Gi memory requests - Created LimitRange for pod/container defaults and maximums - Prevents cluster resource exhaustion and runaway pods 7. **Make Docling processing async** - Wrapped synchronous Docling converter.convert() in asyncio.to_thread() - Prevents blocking the async event loop during CPU-intensive AI processing - Improves API responsiveness during document processing 8. **Add NetworkPolicy resources** - Created comprehensive NetworkPolicy manifests for all components - Implements zero-trust networking with explicit allow rules - Isolates backend, frontend, databases, and storage layers - Restricts egress to only required services (DNS, DBs, external APIs) ## Files Changed ### Backend - backend/rag_solution/router/health_router.py: Added /health/ready endpoint - backend/rag_solution/data_ingestion/docling_processor.py: Async processing, page number fixes ### Kubernetes Manifests - deployment/k8s/base/deployments/backend.yaml: Fixed health probes, image tags - deployment/k8s/base/networkpolicy/*: Added 3 NetworkPolicy manifests - deployment/k8s/base/resourcequota/namespace-quota.yaml: Added ResourceQuota and LimitRange ### Helm Charts - deployment/helm/rag-modulo/values.yaml: Removed hardcoded secrets, added resource quotas, NetworkPolicy config - deployment/helm/rag-modulo/templates/backend-deployment.yaml: Fixed health probes, added startup probe - deployment/helm/rag-modulo/templates/resourcequota.yaml: New ResourceQuota template - deployment/helm/rag-modulo/templates/networkpolicy.yaml: New NetworkPolicy template ## Testing Recommendations 1. Test health endpoints: curl http://backend:8000/api/health/ready 2. Verify secret management with external secrets operator 3. Test pod startup with new startup probe timing 4. Validate NetworkPolicy rules don't block legitimate traffic 5. Confirm resource quotas prevent over-allocation Closes #261 review comments --- .../data_ingestion/docling_processor.py | 17 +- backend/rag_solution/router/health_router.py | 42 +++
