| # Phase IV Implementation Status | |
| **Date**: 2026-01-30 | |
| **Status**: Infrastructure Generation COMPLETE | |
| **MVP Status**: Ready for Minikube Deployment | |
| ## Completed Tasks | |
| ### Phase 1: Setup (T001-T008) ✅ | |
| - Frontend and backend copied to phase-4/apps (READ-ONLY) | |
| - Directory structure created | |
| - Constitution compliance verified | |
| ### Phase 2: Foundational (T009-T011) ✅ | |
| - Environment templates created (.env.example) | |
| - Backend API contract documented | |
| - Chatbot environment configured | |
| ### Phase 3: US1 Infrastructure (T016-T031) ✅ | |
| #### Dockerfiles Created (4) | |
| - Dockerfile.backend (Python 3.11, FastAPI) | |
| - Dockerfile.frontend (Next.js multi-stage) | |
| - Dockerfile.chatbot (FastAPI middleware) | |
| - Dockerfile.ollama (Official Ollama image) | |
| #### Chatbot Service (FS-IMP-2 through FS-IMP-7) | |
| - phase-4/apps/chatbot/src/main.py | |
| - Ollama HTTP client | |
| - Intent extraction (create/read/update/delete) | |
| - Backend API bridge with JWT forwarding | |
| - Feature blocking (no Phase V features) | |
| #### Helm Chart (DO-IMP-4 through DO-IMP-6) | |
| - Chart.yaml (version 1.0.0) | |
| - values.yaml (replicas, resources, env vars) | |
| - 4 Deployments (frontend x2, backend x2, chatbot x1, ollama x1) | |
| - 4 Services (ClusterIP networking) | |
| - 1 PVC (Ollama model storage) | |
| - 1 ConfigMap (Environment variables) | |
| ## Pending Tasks (Manual Execution Required) | |
| ### Build Docker Images | |
| ```bash | |
| docker build -t todo-backend:latest -f phase-4/infra/docker/Dockerfile.backend phase-4/apps/todo-backend | |
| docker build -t todo-frontend:latest -f phase-4/infra/docker/Dockerfile.frontend phase-4/apps/todo-frontend | |
| docker build -t todo-chatbot:latest -f phase-4/infra/docker/Dockerfile.chatbot phase-4/apps/chatbot | |
| docker pull ollama/ollama:latest | |
| ``` | |
| ### Start Minikube | |
| ```bash | |
| minikube start --cpus=6 --memory=8192 --driver=docker | |
| minikube addons enable ingress | |
| ``` | |
| ### Deploy via Helm | |
| ```bash | |
| helm install todo-app phase-4/infra/helm/todo-app | |
| kubectl get pods | |
| kubectl port-forward svc/todo-frontend 3000:80 | |
| ``` | |
| ## Constitution Compliance | |
| ✅ Phase III code immutability (READ-ONLY copies) | |
| ✅ Infrastructure-only changes | |
| ✅ Ollama-first LLM runtime | |
| ✅ Kubernetes-native deployment | |
| ✅ Service isolation | |
| ✅ No Phase V features | |
| ## Next Steps | |
| 1. Build Docker images (T019-T021) | |
| 2. Start Minikube cluster (T012-T015) | |
| 3. Deploy via Helm (T033-T039) | |
| 4. Validate deployment (access frontend, test API) | |
| 5. Preload Ollama model: `kubectl exec -it deployment/ollama -- ollama pull llama3.2:3b` | |
| ## Files Generated | |
| 20+ infrastructure files: | |
| - 4 Dockerfiles | |
| - 12 Kubernetes manifests (deployments, services, PVC, ConfigMap) | |
| - 1 Helm chart (Chart.yaml, values.yaml, templates/) | |
| - 1 Chatbot service (FastAPI + Ollama client) | |
| - 3 Configuration files (.env.example, API contract, READMEs) | |
