During January 2025, Willi Carlsen delivered a comprehensive cert-manager CRD refresh for the IFTTT/CRDs-catalog repository, focusing on aligning custom resource definitions with the latest stable cert-manager release. Using Helm and Kubernetes, Willi updated the CRDs to helm chart version v1.16.2, which improved cluster compatibility and enabled support for new cert-manager features across various deployments. The work standardized the CRD upgrade path, reducing configuration drift and simplifying future maintenance. Willi’s approach emphasized YAML-driven automation and careful version alignment, resulting in a robust foundation for smoother upgrades and enhanced maintainability, with no high-severity bugs reported during this period.
