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

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

minikube start --cpus=6 --memory=8192 --driver=docker
minikube addons enable ingress

Deploy via Helm

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
