Before writing manifests that reference an extended kind, a developer wants to see which custom APIs are installed. Which command best discovers them?
Select an answer to reveal the explanation.
Short Explanation
CRDs are the menu of extra dishes the cluster knows how to cook. kubectl get crd reads that menu before you order. Do not hunt for them in node annotations.
Full Explanation
kubectl get crd lists CustomResourceDefinitions installed in the cluster; kubectl api-resources also surfaces served kinds. Discovering extensions before authoring manifests prevents applying unknown types. Node listings and unrelated auth can-i checks do not inventory CRDs.
