- Source Control: Code changes trigger automated pipeline
- Build Stage: Docker image creation with optimization
- Registry Push: Automated versioning and storage
- Deployment Stage: Kubernetes rolling update execution
- Verification: Health checks and deployment validation
Problem: Flask server couldn't serve frontend static files after containerization Solution: Restructured Dockerfile with proper COPY commands and configured Flask static folder mapping
Problem: Updated images weren't being pulled due to Kubernetes caching
Solution: Implemented imagePullPolicy: Always and rolling restart strategy
Problem: Frontend couldn't communicate with containerized backend Solution: Configured proper CORS headers and API endpoint structuring
