Worked on the kairos-io/provider-kubeadm repository to enhance build stability and CI reliability by upgrading the Go toolchain to version 1.26.5. This involved aligning the Go version across go.mod, Dockerfile, Earthfile, and GitHub Actions workflows, ensuring a consistent development and deployment environment. Leveraged skills in Go, Docker, and CI/CD best practices to reduce environment drift and eliminate inconsistencies that can lead to flaky builds. The changes streamlined the onboarding process for contributors and accelerated pull request validation, resulting in more predictable releases. No major bugs were reported or fixed during this period, with efforts focused on infrastructure improvements.
