When using kubectl get -o yaml/json to obtain resource information, the output content is too detailed, how to obtain the specified part of the content?
[root@ops-harbor ~]# kubectl get -n monitoring prometheus-prome-prometheus-operator-prometheus-0 -ojson

# ...long long content
For example, I only want to get the following 2 sections of information.
"apiVersion": "v1",
"kind": "Pod",
"ownerReferences": [
{
"apiVersion": "apps/v1",
"blockOwnerDeletion": true,
"controller": true,

"name": "prometheus-prome-prometheus-operator-prometheus",

}
kubectl get pod -n monitoring prometheus-prome-prometheus-operator-prometheus-0 -o json | jq .metadata.ownerReferences
or
kubectl get pod -n monitoring prometheus-prome-prometheus-operator-prometheus-0 -o jsonpath={.metadata.ownerReferences} | jq
