Worked on the aquasecurity/trivy-operator repository to improve the reliability of container image reference parsing, focusing on scenarios where image references include only a digest. Addressed a parsing bug by updating the ParseImageRef function to correctly extract tags and handle various image reference formats, both with and without tags and digests. Enhanced the test suite by adding comprehensive unit tests, ensuring robust coverage and preventing future regressions. Utilized Go for development and testing, applying test-driven development practices to strengthen the stability of image handling in CI and runtime workflows, ultimately supporting safer and more predictable image scanning and deployment pipelines.
