Each service includes:
- CircleCI pipeline with lint, build, deploy stages
- Multi-stage Dockerfile (Lumen/Oracle optimized)
- Deployment scripts with critical fixes
- Complete Helm charts with CronJob templates
- GitHub Actions workflow for secrets management
- Comprehensive documentation

Special features:

## Special Considerations

### tbi-acc-cron-service
- Uses Laravel Lumen's built-in scheduler
- Requires proper Laravel environment configuration
- May need Redis/Elasticsearch connectivity
- Schedule can be adjusted in values.yaml

### tbi-acc-package-cron
- Requires Oracle Instant Client (included in Docker image)
- Needs Oracle TNS configuration
- Requires both Oracle and MySQL credentials
- Large memory footprint due to Oracle client
- Schedule should align with data sync requirements

---

## Monitoring

### CronJob Monitoring Commands

```bash
# List all CronJobs in access namespace
kubectl get cronjobs -n access

# Check recent jobs
kubectl get jobs -n access -l app=tbi-acc-cron-service --sort-by=.metadata.creationTimestamp
kubectl get jobs -n access -l app=tbi-acc-package-cron --sort-by=.metadata.creationTimestamp

# View logs
kubectl logs -n access -l app=tbi-acc-cron-service --tail=100
kubectl logs -n access -l app=tbi-acc-package-cron --tail=100

# Check for failed jobs
kubectl get jobs -n access --field-selector status.successful=0
```

---

## Success Criteria

- ✅ All files created and staged
- ✅ CircleCI configs validated
- ✅ Dockerfiles tested (syntax)
- ✅ Helm charts structured correctly
- ✅ Documentation complete
- ⏳ Deployments successful in dev
- ⏳ CronJobs executing on schedule
- ⏳ No errors in logs
