Developed comprehensive Kubernetes conformance testing workflow documentation for the loft-sh/vcluster repository, focusing on upgrade compatibility up to Kubernetes 1.32. The work detailed the setup of Minikube and vcluster environments, deployment of Sonobuoy, and provided step-by-step instructions for generating and interpreting conformance results. By leveraging Bash, YAML, and Go, the documentation established a reproducible process for teams to verify cluster compliance and streamline upgrade cycles. This contribution improved test coverage and ensured adherence to upstream standards, enabling faster, safer upgrades. The approach emphasized clarity and reproducibility, supporting certified conformance testing within CI/CD pipelines and enhancing overall documentation quality.
