Developed a comprehensive KubeVela toolset for the robusta-dev/holmesgpt repository, focusing on application management and troubleshooting within Kubernetes environments. The work involved exposing vela CLI commands to manage applications, components, workflows, and traits, as well as implementing features for status checks, log retrieval, resource monitoring, and live-diff previews. Extensive documentation and integration into site navigation were provided to support developer onboarding. End-to-end test fixtures were created to validate installation, simulate deployment failures, and verify diagnostic workflows, including LLM-based evaluation paths. The project leveraged Bash, YAML, and DevOps practices to enhance observability and streamline Kubernetes-based deployment processes.
