Worked on the runatlantis/atlantis repository to enhance the security and reliability of the release process by implementing image attestation and container signing for Docker images. Focused on strengthening supply chain integrity, the work introduced provenance recording and integrated cosign for pre-release container signing. Expanded platform support by enabling multi-platform builds using Go, QEMU, and Docker, while optimizing build workflows to accelerate deployments. Improved the CI/CD pipeline by hardcoding platforms and refining the GitHub Actions matrix, ensuring consistent multi-architecture builds. Utilized YAML for workflow configuration and addressed reliability issues, resulting in a more reproducible and secure release process.
