Worked on the traefik/traefik-helm-chart repository to streamline Custom Resource Definition (CRD) management by removing the deprecated APIAccess resource and aligning configurations with APICatalogItems and ManagedSubscription. This update involved editing YAML manifests and Helm chart templates to reduce the CRD surface area, simplify ongoing maintenance, and improve upgrade paths for users. The work included updating kustomization files, admission controller webhooks, and RBAC cluster roles to eliminate references to outdated resources, ensuring configuration consistency. Leveraging skills in Kubernetes, Helm, and CRD management, the changes delivered a more stable deployment experience and reduced operational overhead for Helm chart users.
