🚧 Known Issues & Fixes

Issue 1: Backend Missing Dependency

Error: ImportError: email-validator is not installed

Fix: Add to phase-4/apps/todo-backend/requirements.txt:

email-validator==2.1.0

Steps:

Add email-validator==2.1.0 to requirements.txt
Rebuild image: docker build -t todo-backend:latest -f phase-4/infra/docker/Dockerfile.backend phase-4/apps/todo-backend
Restart: docker-compose -f phase-4/infra/docker/docker-compose-backend-only.yml restart backend

Issue 2: Ollama Model Pull Timeout

Error: TLS handshake timeout when pulling llama3.2:3b (2GB model)

Workaround: The model pull timed out due to network issues.

Options:

Retry later when network is stable:

docker exec todo-ollama ollama pull llama3.2:3b

Use smaller model:

docker exec todo-ollama ollama pull qwen2.5:0.5b

Pre-download manually and load into container

Issue 3: Frontend Build Pending

Status: Frontend image not yet built due to Docker network issues

Next Steps:

Fix Docker Desktop proxy settings
Build image: cd phase-4/apps/todo-frontend && docker build -t todo-frontend:latest -f ../../infra/docker/Dockerfile.frontend .
Test frontend: http://localhost:3000

🎯 What's Working Right Now

✅ Working Services

PostgreSQL Database: Running and healthy
- Port: 5432
- Database: tododb
- User: todo
- Password: password
Ollama LLM Runtime: Running and healthy
- Port: 11434
- API: http://localhost:11434
- Status: Ready (model needs to be pulled)
Chatbot Service: Running and healthy
- Port: 8001
- Health: http://localhost:8001/api/health
- Dependencies: Backend (down), Ollama (up)

⚠️ Partially Working

Backend Service: Built but needs dependency
- Port: 8000
- Issue: Missing email-validator
- Fix: Simple rebuild after adding dependency

🚀 Quick Fix Instructions

Fix Backend (5 minutes)

# 1. Add missing dependency
echo "email-validator==2.1.0" >> phase-4/apps/todo-backend/requirements.txt

# 2. Rebuild backend image
docker build -t todo-backend:latest -f phase-4/infra/docker/Dockerfile.backend phase-4/apps/todo-backend

# 3. Restart backend
docker-compose -f phase-4/infra/docker/docker-compose-backend-only.yml restart backend

# 4. Verify
docker logs todo-backend --tail=20
curl http://localhost:8000/api/health

Pull Ollama Model (5-10 minutes)

# Wait for network stability, then:
docker exec todo-ollama ollama pull llama3.2:3b

# Or use smaller model (faster):
docker exec todo-ollama ollama pull qwen2.5:0.5b

# Verify model loaded:
docker exec todo-ollama ollama list

Build Frontend (10-15 minutes)

# Navigate to frontend
cd phase-4/apps/todo-frontend

# Build image
docker build -t todo-frontend:latest -f ../../infra/docker/Dockerfile.frontend .

# Add to docker-compose or run separately:
docker run -p 3000:3000 -e NEXT_PUBLIC_BACKEND_URL=http://host.docker.internal:8000 todo-frontend:latest

📝 Testing Commands

Test Backend (after fix)

# Health check
curl http://localhost:8000/api/health

# Should return: {"status":"healthy","version":"1.0.0"}

Test Chatbot (after backend and Ollama are ready)

# Health check
curl http://localhost:8001/api/health

# Test chat endpoint
curl -X POST http://localhost:8001/api/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "create a todo to buy groceries"}'

Test Ollama (after model pull)

# List models
docker exec todo-ollama ollama list

# Test model
docker exec todo-ollama ollama run llama3.2:3b "test"

📊 Overall Progress

Infrastructure Generation: ✅ 100% Docker Images Built: ✅ 75% (3 of 4) Services Running: ✅ 75% (3 of 4 healthy) Dependencies Fixed: ⚠️ 50% (1 of 2 issues resolved) Model Loaded: ⏳ 0% (network timeout)

Estimated Time to Full Deployment: 30-45 minutes

🎯 Next Steps Priority

Priority 1: Fix Backend (5 min)

Add email-validator to requirements.txt
Rebuild backend image
Restart backend service
Test API health

Priority 2: Pull Ollama Model (10 min)

Retry llama3.2:3b pull
Or use smaller model qwen2.5:0.5b
Verify model is loaded
Test Ollama API

Priority 3: Test End-to-End (10 min)

Test backend API
Test chatbot → Ollama → Backend flow
Create todo via chatbot
Verify all CRUD operations

Priority 4: Build Frontend (15 min)

Fix Docker network issues
Build frontend image
Deploy frontend service
Test full stack

✅ Success Criteria

When ALL of these are true, Phase IV deployment is complete:

All 4 Docker images built (frontend, backend, chatbot, ollama)
All 5 containers running and healthy
Backend API returns 200 OK
Chatbot API returns 200 OK
Ollama model loaded (llama3.2:3b or qwen2.5:0.5b)
Frontend loads at http://localhost:3000
Can create todo via chatbot
All CRUD operations work
