## 🔧 Technical Implementation Details
### Key Files Modified
- `app/core/kubernetes_client.py` - SSL fallback for cluster compatibility
- `app/core/prometheus_client.py` - ServiceAccount token authentication
- `app/services/validation_service.py` - Enhanced resource validation engine
- `app/static/index.html` - Pragmatic dashboard with modal-based analysis
- `app/models/resource_models.py` - Updated models for container data structure
- `k8s/deployment.yaml` - Cluster-agnostic security context
- `k8s/route.yaml` - Dynamic hostname generation
### Critical Fixes Applied
1. **SSL Connection**: Fallback to disable SSL verification when CA cert is empty
2. **SCC Compatibility**: Removed hardcoded UIDs, let OpenShift assign them
3. **Route Agnostic**: Removed hardcoded hostname, let OpenShift generate it
4. **Image Pull**: Docker Hub secret configuration
5. **Prometheus Integration**: ServiceAccount token authentication
6. **Data Structure Fix**: Updated PodResource model to handle container dictionaries
7. **Validation Engine**: Fixed container resource access in validation_service.py
8. **UI/UX**: Replaced browser alerts with professional modals
## 🐛 Known Issues
### 1. Historical Analysis Data
**Status**: ⚠️ **SHOWING ZEROS**
**Issue**: Prometheus queries return zero values for CPU/memory usage
**Location**: `app/services/historical_analysis.py`
**Impact**: Historical analysis appears empty
**Next Steps**: Debug PromQL queries and metric availability
### 2. Export Functionality
**Status**: ⚠️ **NEEDS TESTING**
**Issue**: Export functionality needs validation with current implementation
**Location**: `app/services/report_service.py`
**Impact**: Users may not get proper export files
**Next Steps**: Test and fix file download mechanism
