Add production-ready deployment configuration for Raspberry Pi cluster with comprehensive documentation and automation scripts. Kubernetes Manifests (deploy/k8s/): - namespace.yaml - Dedicated namespace for the application - configmap.yaml - Environment configuration (MongoDB URI, ports, URLs) - secrets.yaml.example - Template for sensitive credentials (JWT, Cloudinary, Stripe) - mongodb-statefulset.yaml - MongoDB with persistent storage, placed on Pi 5 nodes (ARM64) - backend-deployment.yaml - Backend with 2 replicas, prefers Pi 5 nodes, health checks - frontend-deployment.yaml - Frontend with 2 replicas, can run on any node, nginx-based - ingress.yaml - Traefik/NGINX ingress for API, Socket.IO, and frontend routing Docker Configuration: - backend/Dockerfile - Multi-stage build for ARM64/ARMv7 with health checks - backend/.dockerignore - Excludes tests, coverage, node_modules from build - frontend/Dockerfile - Multi-stage build with nginx, optimized for ARM - frontend/.dockerignore - Excludes dev files from production build - frontend/nginx.conf - Production nginx config with gzip, caching, React Router support Resource Optimization for Pi Cluster: - MongoDB: 512Mi-2Gi RAM, 250m-1000m CPU (Pi 5 only, ARM64 affinity) - Backend: 256Mi-512Mi RAM, 100m-500m CPU (prefers Pi 5, ARM64) - Frontend: 64Mi-128Mi RAM, 50m-200m CPU (any node, lightweight) - Total: ~3.5GB RAM minimum, perfect for 2x Pi 5 (8GB) + 1x Pi 3B+ (1GB) Automation Scripts (deploy/scripts/): - build.sh - Build multi-arch images (ARM64/ARMv7) and push to registry - deploy.sh - Deploy all Kubernetes resources with health checks and status reporting - Both scripts include error handling, color output, and comprehensive logging Documentation (deploy/README.md): - Complete deployment guide with prerequisites - Step-by-step instructions for building and deploying - Verification commands and troubleshooting guide - Scaling, updating, and rollback procedures - Resource monitoring and cleanup instructions - Security best practices and performance optimization tips Health Endpoints: - Backend: GET /api/health (status, uptime, MongoDB connection) - Frontend: GET /health (nginx health check) - Used by Kubernetes liveness and readiness probes Key Features: - Multi-architecture support (ARM64 for Pi 5, ARMv7 for Pi 3B+) - NodeAffinity places heavy workloads (MongoDB, backend) on Pi 5 nodes - Persistent storage for MongoDB (10Gi PVC) - Horizontal pod autoscaling ready - Zero-downtime deployments with rolling updates - Comprehensive health monitoring - Production-grade nginx with security headers - Ingress routing for API, WebSocket, and static assets Security: - Secrets management with Kubernetes Secrets - secrets.yaml excluded from Git (.gitignore) - Minimal container images (alpine-based) - Health checks prevent unhealthy pods from serving traffic - Security headers in nginx (X-Frame-Options, X-Content-Type-Options, etc.) Usage: 1. Build images: ./deploy/scripts/build.sh 2. Configure secrets: cp deploy/k8s/secrets.yaml.example deploy/k8s/secrets.yaml 3. Deploy: ./deploy/scripts/deploy.sh 4.
