April 2025 monthly summary for openshift/sandboxed-containers-operator focusing on runtime portability improvements and CI reliability. Key achievements: - Portability fix implemented by updating the Makefile to use CONTAINER_TOOL instead of hardcoding docker, enabling builds with Podman and other runtimes across bundle-build and catalog-build targets. Major bugs fixed: - Fixed container runtime portability issue by removing runtime hardcoding, ensuring a runtime-agnostic build flow within the operator repository. Overall impact and business value: - Improved cross-runtime portability reduces build failures and accelerates local development, CI pipelines, and deployments in diverse environments. Positions the project to support multi-runtime strategies with lower maintenance overhead. Technologies and skills demonstrated: - Makefile parameterization and environment-driven builds (CONTAINER_TOOL) - Cross-runtime compatibility (Docker/Podman parity) - Debugging and root-cause analysis leading to reliable build pipelines - Commit-based traceability (single commit ce76638168059c4c432759716504f2da5490df65)
