Kubernetes, List Custom Resources Definitions using Kubectl

Custom Resources are like any other native Kubernetes resource.

All the basic kubeclt CRUD operations work fine for CRDs. So just use any of the below commands.

kubectl get crd <name of crd>
kubectl describe crd <name of crd>
kubectl get crd <name of crd> -o yaml 

It is also possible to list CRDs by filtering by API Groups:

kubectl api-resources --api-group=cert-manager.io

Will return:

NAME                  SHORTNAMES   APIVERSION           NAMESPACED   KIND
certificaterequests   cr,crs       cert-manager.io/v1   true         CertificateRequest
certificates          cert,certs   cert-manager.io/v1   true         Certificate
clusterissuers                     cert-manager.io/v1   false        ClusterIssuer
issuers                            cert-manager.io/v1   true         Issuer
