During a two-month period, Mateusz Kosiarczyk enhanced the konflux-ci/build-tasks-dockerfiles and konflux-ci/e2e-tests repositories by delivering three targeted features focused on release reliability and test coverage. He upgraded CI/CD pipelines to use Trusted Artifacts and introduced release gating with Tekton, leveraging Go and YAML to enforce artifact integrity and automate rpm-signature scanning. In parallel, he refactored SBOM generation scripts for more accurate Dockerfile JSON parsing, improving supply-chain transparency. For end-to-end testing, he added OCI-archive Dockerfile support and custom build context handling, using Go and containerization tools to increase build reproducibility and reduce risk in production releases.
