Worked on stabilizing the CI/CD pipeline for the tmforum-oda/oda-canvas repository, focusing on improving the reliability of automated Docker image signing during release workflows. Addressed a critical issue in GitHub Actions by correcting the base64 decoding and handling of the COSIGN_KEY, ensuring the cosign.key file is properly written and preventing signing errors that previously disrupted releases. Leveraged skills in CI/CD, Docker, and GitHub Actions, with workflow automation implemented in YAML. While no new features were introduced, the work reduced pipeline failures and manual intervention, resulting in faster, more predictable releases and enhanced security for the release process.
