|
||||
```bash
|
||||
# Start all services including demo system

## 🔧 Configuration
|
||||
|
||||
### Session Settings
|
||||
|
||||
Edit `services/demo_session/app/core/config.py`:
|
||||
|
||||
```python
|
||||
DEMO_SESSION_DURATION_MINUTES = 30 # Session lifetime
|
||||
DEMO_SESSION_MAX_EXTENSIONS = 3 # Max extensions allowed
|
||||
REDIS_SESSION_TTL = 1800 # Redis cache TTL (seconds)
|
||||
```
|

|
||||
|
||||
```python
|
||||
DEMO_ALLOWED_OPERATIONS = {
|
||||
"GET": ["*"],
|
||||
"POST": [

|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📈 Monitoring
|
||||
|
||||
### Check Active Sessions
|
||||
|
||||
```bash
|
||||
# Get statistics
|
||||
curl http://localhost/api/demo/stats | jq
|
||||
|
||||
# Get specific session
|
||||
curl http://localhost/api/demo/session/{session_id} | jq
|
||||
```
|
||||
|
||||
### View Logs
|
||||
|
||||
```bash
|
||||
# Demo session service
|
||||
kubectl logs -f deployment/demo-session-service -n bakery-ia
|
||||
|
||||
# Cleanup job
|
||||
kubectl logs -l app=demo-cleanup -n bakery-ia --tail=100
|
||||
|
||||
# Seed jobs
|
||||
kubectl logs job/demo-seed-inventory -n bakery-ia
|
||||
```
|
||||
|
||||
### Metrics
|
||||
|
||||
```bash
|
||||
# Database queries
|
||||
kubectl exec -it deployment/demo-session-service -n bakery-ia -- \
|
||||
psql $DEMO_SESSION_DATABASE_URL -c \
|
||||
"SELECT status, COUNT(*) FROM demo_sessions GROUP BY status;"
|
||||
|
||||
# Redis memory
|
||||
kubectl exec -it deployment/redis -n bakery-ia -- \
|
||||
redis-cli INFO memory
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔄 Maintenance
|
||||
|
||||
### Manual Cleanup
|
||||
|
||||
```bash
|
||||
# Trigger cleanup manually
|
||||
kubectl create job --from=cronjob/demo-session-cleanup \
|
||||
manual-cleanup-$(date +%s) -n bakery-ia
|
||||
|
||||
# Watch cleanup progress
|
||||
kubectl logs -f job/manual-cleanup-xxxxx -n bakery-ia
|
||||
```
|
||||
|
||||
### Reseed Demo Data
|
||||
|
||||
```bash
|
||||
# Delete and recreate seed jobs
|
||||
kubectl delete job demo-seed-inventory -n bakery-ia
|
||||
kubectl apply -f infrastructure/kubernetes/base/jobs/demo-seed-inventory-job.yaml
|
||||
|
||||
# Watch progress
|
||||
kubectl logs -f job/demo-seed-inventory -n bakery-ia
|
||||
```
|
||||
|
||||
### Scale Demo Service
|
||||
|
||||
```bash
|
||||
# Scale up for high load
|
||||
kubectl scale deployment/demo-session-service --replicas=4 -n bakery-ia
|
||||
|
||||
# Scale down for maintenance
|
||||
kubectl scale deployment/demo-session-service --replicas=1 -n bakery-ia
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🛠 Troubleshooting
|
||||
|
||||
### Sessions Not Creating
|
||||
|
||||
1. **Check demo-session-service health**
|
||||
```bash
|
||||
kubectl get pods -l app=demo-session-service -n bakery-ia
|
||||
kubectl logs deployment/demo-session-service -n bakery-ia --tail=50
|
||||
```
|
||||
|
||||
2. **Verify base tenants exist**
|
||||
```bash
|
||||
kubectl exec -it deployment/tenant-service -n bakery-ia -- \
|
||||
psql $TENANT_DATABASE_URL -c \
|
||||
"SELECT id, name, is_demo_template FROM tenants WHERE is_demo = true;"
|
||||
```
|
||||
|
||||
3. **Check Redis connection**
|
||||
```bash
|
||||
kubectl exec -it deployment/demo-session-service -n bakery-ia -- \
|
||||
python -c "import redis; r=redis.Redis(host='redis-service'); print(r.ping())"
|
||||
```
|
||||
|
||||
### Sessions Not Cleaning Up
|
||||
|
||||
1. **Check CronJob status**
|
||||
```bash
|
||||
kubectl get cronjobs -n bakery-ia
|
||||
kubectl get jobs -l app=demo-cleanup -n bakery-ia
|
||||
```
|
||||
|
||||
2. **Manually trigger cleanup**
|
||||
```bash
|
||||
curl -X POST http://localhost/api/demo/cleanup/run
|
||||
```
|
||||
|
||||
3. **Check for stuck sessions**
|
||||
```bash
|
||||
kubectl exec -it deployment/demo-session-service -n bakery-ia -- \
|
||||
psql $DEMO_SESSION_DATABASE_URL -c \
|
||||
"SELECT session_id, status, expires_at FROM demo_sessions WHERE status = 'active';"
|
||||
```
|
||||
|
||||
### Gateway Not Injecting Virtual Tenant
|
||||
|
||||
1. **Check middleware is loaded**
|
||||
```bash
|
||||
kubectl logs deployment/gateway -n bakery-ia | grep -i demo
|
||||
```
|
||||
|
||||
2. **Verify session ID in request**
|
||||
```bash
|
||||
curl -v http://localhost/api/inventory/ingredients \
|
||||
-H "X-Demo-Session-Id: your-session-id"
|
||||
```
|
||||
|
||||
3. **Check demo middleware logic**
|
||||
- Review [demo_middleware.py](gateway/app/middleware/demo_middleware.py)
|
||||
- Ensure session is active
|
||||
- Verify operation is allowed
|
||||
|
||||
---
|
||||
|
||||

## 📚 Next Steps
|
||||
|
||||
### For Frontend Integration
|
||||
|
||||
1. Create demo login page showing both accounts
|
||||
2. Implement session token storage (cookie/localStorage)
|
||||
3. Add session timer UI component
|
||||
4. Show "DEMO MODE" badge in header
|
||||
5. Display session expiration warnings
|
||||
|
||||
### For Marketing
|
||||
|
||||
1. Publish demo credentials on website
|
||||
2. Create demo walkthrough videos
|
||||
3. Add "Probar Demo" CTA buttons
|
||||
4. Track demo → signup conversion
|
||||
|
||||
### For Operations
|
||||
|
||||
1. Set up monitoring dashboards
|
||||
2. Configure alerts for cleanup failures
|
||||
3. Track session metrics (duration, usage)
|
||||
4. Optimize Redis cache strategy

## 🔧 Technical Architecture Decisions
|
||||
|
||||
### Data Cloning: Why Kubernetes Jobs?
|
||||
|
||||
**Problem**: Need to clone demo data from base template tenants to virtual tenants for each session.
|
||||
|
||||
**Options Considered**:
|
||||
1. ❌ **Service-based clone endpoints** - Would require `/internal/demo/clone` in every service
|
||||
2. ❌ **PostgreSQL Foreign Data Wrapper** - Complex setup, doesn't work across databases
|
||||
3. ✅ **Kubernetes Jobs** - Selected approach
|
||||
|
||||
**Why K8s Jobs Won**:
|
||||
- Database-level operations (ORM-based, faster than API calls)
|
||||
- Scalable (one job per session, isolated execution)
|
||||
- No service coupling (don't need clone endpoints in every service)
|
||||
- Works in all environments (dev & production)
|
||||
|
||||
### Image Configuration: Environment Variables
|
||||
|
||||
**Problem**: K8s Jobs need container images, but Tilt uses dynamic tags (e.g., `tilt-abc123`) while production uses stable tags.
|
||||
|
||||
**Solution**: Environment variable `CLONE_JOB_IMAGE`
|
||||
```yaml
|
||||
# Demo-session deployment has default
|
||||
env:
|
||||
- name: CLONE_JOB_IMAGE
|
||||
value: "bakery/inventory-service:latest"
|
||||
|
||||
# Tilt patches it dynamically
|
||||
# Tiltfile line 231-237
|
||||
inventory_image_ref = kubectl get deployment inventory-service ...
|
||||
kubectl set env deployment/demo-session-service CLONE_JOB_IMAGE=$inventory_image_ref
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- ✅ General solution (not tied to specific service)
|
||||
- ✅ Works in dev (dynamic Tilt tags)
|
||||
- ✅ Works in production (stable release tags)
|
||||

### Middleware: BaseHTTPMiddleware Pattern
|
||||
|
||||
**Problem**: Initial function-based middleware using `@app.middleware("http")` wasn't executing.
|
||||
|
||||
**Solution**: Converted to class-based `BaseHTTPMiddleware`
|
||||
```python
|
||||
class DemoMiddleware(BaseHTTPMiddleware):
|
||||
async def dispatch(self, request: Request, call_next):
|
||||
# ... middleware logic
|
||||
```
|
||||
|
||||
**Why**: FastAPI's `BaseHTTPMiddleware` provides better lifecycle hooks and guaranteed execution order.
