Question

A developer must fill required fields on a custom resource whose schema is unfamiliar. Which kubectl aid helps document those fields?

Accepted Answer

kubectl explain <crd-kind>.spec (and nested paths) to explore the CR schema. — kubectl explain is the in-cluster field guide—point it at kind.spec and it walks the properties. Use it for CRDs the same way you do for Pods. No need to cordon nodes to read a schema.

Answer

kubectl attach to a random Pod and hope the schema is printed on stdout.

Answer

kubectl cordon each node to dump CRD OpenAPI into kubelet logs.

Answer

kubectl taint the control plane with explain=true to enable schema comments.
