### Earlier Checkpoints
✅ Project structure planning (CLAUDE.md)
✅ Implementation plan created (docs/PLAN.md)
✅ Progressive approach defined
✅ Step 1: Minimal Foundation - Docker + Console Hello World
✅ Step 2: Add First Service (Users)
✅ Step 3: Database Integration

## Active Working Files
```
주요 작업 파일:
- /services/console/backend/ (Console Backend - FastAPI)
- /services/console/frontend/ (Console Frontend - React + TypeScript)
- /docs/CONSOLE_ARCHITECTURE.md (시스템 아키텍처)
- /docs/PLAN.md (구현 계획)

## Deployment Status

### KIND Cluster: site11-dev ✅
**Cluster Created**: 2025-10-28
**Nodes**: 5 (1 control-plane + 4 workers)

```bash
# Console Namespace
kubectl -n site11-console get pods
# Status: 4/4 Running (mongodb, redis, console-backend, console-frontend)

# Cluster Status
./scripts/kind-setup.sh status

# Management
./scripts/kind-setup.sh {create|delete|deploy-console|status|logs|access|setup}
```

### Access URLs (NodePort)
- Frontend: http://localhost:3000 (NodePort 30080)
- Backend API: http://localhost:8000 (NodePort 30081)
- Backend Health: http://localhost:8000/health
- API Docs: http://localhost:8000/docs

### Monitoring
```bash
# Start monitoring
docker-compose -f docker-compose.kubernetes.yml up -d
docker-compose -f docker-compose.kubernetes.yml logs -f kind-monitor
```

## Next Immediate Steps (Phase 2)

### Service Management CRUD
```
1. Backend API for service management
   - Service model (name, url, status, health_endpoint)
   - CRUD endpoints
   - Health check mechanism

2. Frontend Service Management UI
   - Service list page
   - Add/Edit service form
   - Service status display
   - Health monitoring

3. Service Discovery & Registry
   - Auto-discovery of services
   - Heartbeat mechanism
   - Status dashboard
```

## Important Decisions Made
1. **Architecture**: API Gateway Pattern with Console as orchestrator
2. **Tech Stack**: FastAPI + React + MongoDB + Redis + Docker + Kubernetes
3. **Authentication**: JWT with access/refresh tokens
4. **Password Security**: bcrypt (not passlib)
5. **Frontend State**: React Context API (not Redux)
6. **API Client**: Axios with interceptors for token management
7. **Deployment**: Kubernetes on Docker Desktop
8. **Docker Registry**: Docker Hub (yakenator)

## Questions to Ask When Resuming
새로운 세션에서 이어서 작업할 때 확인할 사항:
1. "Phase 1 (Authentication) 완료 확인?"
2. "Kubernetes 클러스터 정상 동작 중?"
3. "다음 Phase 2 (Service Management) 시작할까요?"

## Git Workflow
```bash
# Current branch
main

# Commit pattern
git add .
git commit -m "feat: Phase 1 - Complete authentication system

- Backend: JWT auth with FastAPI + MongoDB
- Frontend: Login/Register with React + TypeScript
- Docker images built and deployed to Kubernetes
- All authentication endpoints tested

git push origin main
```

## Context Recovery Commands
새 세션에서 빠르게 상황 파악하기:
```bash
# 1. 현재 구조 확인
ls -la services/console/

# 2. 진행 상황 확인
cat docs/PROGRESS.md | grep "Current Phase"

# 3. Kubernetes 상태 확인
kubectl -n site11-pipeline get pods

# 4. Docker 이미지 확인
docker images | grep console

# 5. Git 상태 확인
git status
git log --oneline -5
```

## Troubleshooting Log

### Issue 1: Bcrypt 72-byte limit
**Error**: `ValueError: password cannot be longer than 72 bytes`
**Solution**: Replaced `passlib[bcrypt]` with native `bcrypt==4.1.2`
**Status**: ✅ Resolved

### Issue 2: Pydantic v2 incompatibility
**Error**: `__modify_schema__` not supported
**Solution**: Updated to `__get_pydantic_core_schema__` and `model_config = ConfigDict(...)`
**Status**: ✅ Resolved

### Issue 3: Port forwarding disconnections
**Error**: Lost connection to pod
**Solution**: Kill kubectl processes and restart port forwarding
**Status**: ⚠️ Known issue (Kubernetes restarts)

## Notes for Next Session

- 모든 코드는 services/console/ 디렉토리에 있음
- Docker 이미지는 yakenator/site11-console-* 로 푸시됨
- Kubernetes에 배포되어 있음 (site11-pipeline namespace)
