Abhi Kapoor upgraded Argo CD to version 3 in the zapier/kubechecks repository, focusing on resolving an annotation tracking bug that previously affected deployment reliability. Using Go, Helm, and Kubernetes, Abhi tuned memory limits and adjusted cluster configurations to ensure compatibility with the new Argo CD version. The work emphasized stability, achieving smoother deployments and reducing the risk of future upgrade issues. By implementing these changes with minimal downtime and improving monitoring signals, Abhi enabled more robust GitOps workflows. The depth of the work lay in careful orchestration of infrastructure updates, addressing both immediate bugs and long-term maintainability concerns.
