json – parsing jsonpath with kubectl

I would try to keep it simple by using custom-columns:

kubectl get pod -o custom-columns="POD-NAME":.metadata.name,"NAMESPACE":.metadata.namespace,"CONTAINER-IMAGES":.spec.containers[*].image,"DNS-POLICY":.spec.dnsPolicy
POD-NAME   NAMESPACE   CONTAINER-IMAGES   DNS-POLICY
bar        default     nginx              ClusterFirst
foo        default     nginx              ClusterFirst
zoo        default     nginx,ubuntu       ClusterFirst

Using jsonpath:

kubectl get pod -o jsonpath="{range .items[*]}{.metadata.name},{.spec.containers[*].image},{.spec.dnsPolicy}{"\n"}{end}"
bar,nginx,ClusterFirst
foo,nginx,ClusterFirst
zoo,nginx ubuntu,ClusterFirst
