During an audit, a municipal SRE needs to see which API extensions are installed. Which approach inventories CustomResourceDefinitions in the cluster?
Select an answer to reveal the explanation.
Short Explanation
kubectl get crds (apiextensions.k8s.io) is the audit clipboard for “what custom APIs did we install?” Image lists and swap metrics will not tell you. Inventory the API extensions where they live—in the API.
Full Explanation
CustomResourceDefinitions are API objects in the apiextensions.k8s.io group. Administrators inventory them with kubectl get crd/crds or equivalent API queries during audits. Runtime image lists, kubelet metrics, and Endpoints objects do not provide a complete CRD catalog.
