Worked on deployment stability for the gchq/CyberChef repository by updating the Dockerfile to use the nginx-unprivileged image and exposing port 8080, aligning the application with Kubernetes best practices. This change improved security by reducing container privileges and enhanced compatibility with cloud-native environments. The update included clear documentation and a breaking-change note to ensure release traceability and smooth adoption. Focused on DevOps processes, Docker, and Kubernetes, the work emphasized deployment reliability and security hardening rather than bug fixes. The approach demonstrated attention to release hygiene and cloud readiness, resulting in more stable and maintainable Kubernetes deployments for CyberChef.
