During August 2025, Lhh worked on the konflux-ci/release-service-catalog repository, focusing on stabilizing Docker image signing workflows and improving test coverage for Docker image handling. Lhh addressed a bug in the rh-sign-image task, ensuring correct processing and signing of multi-architecture and index Docker images by refining manifest media type handling. To reduce release risk and speed up triage, Lhh enhanced the test suite by updating the mock skopeo command to return detailed JSON manifests and expanding multi-component coverage. This work leveraged skills in CI/CD, containerization, and testing, using Shell and YAML to deliver more reliable image management processes.
