Sebastien Masset enhanced the kairos-io/kairos repository by implementing Ubuntu 24.04 image support within the release workflow, enabling automatic building of k0s images for this new OS version during releases. He approached the task by updating YAML-based CI/CD pipelines and leveraging GitHub Actions to automate image builds and approvals, which reduced manual intervention and improved deployment flexibility. This work expanded OS compatibility and ensured reproducible builds, aligning with DevOps best practices. Over the course of one month, Sebastien focused on workflow automation and traceability, demonstrating depth in CI/CD and DevOps while addressing the need for broader environment support.
