feat: Setup KIND cluster for local Kubernetes development
- Created 5-node KIND cluster (1 control-plane + 4 workers) - Configured NodePort mappings for console access (30080, 30081) - Created namespace separation (site11-console, site11-pipeline) - Deployed MongoDB and Redis in KIND cluster - Deployed Console backend and frontend with NodePort services - All 4 pods running successfully and verified with browser test Infrastructure: - k8s/kind-dev-cluster.yaml: 5-node cluster configuration - k8s/kind/console-mongodb-redis.yaml: Database deployments - k8s/kind/console-backend.yaml: Backend with NodePort - k8s/kind/console-frontend.yaml: Frontend with NodePort Management Tools: - scripts/kind-setup.sh: Comprehensive cluster management script - docker-compose.kubernetes.yml: Monitoring helper services Documentation: - KUBERNETES.md: Complete usage guide for developers - docs/KIND_SETUP.md: Detailed KIND setup documentation - docs/PROGRESS.md: Updated with KIND cluster completion Console Services Access: - Frontend: http://localhost:3000 (NodePort 30080) - Backend: http://localhost:8000 (NodePort 30081) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
