some examples
# get all pod names
$ kubectl get pods -o jsonpath='{.items[*].metadata.name}'
# get all container image name in use by all pods in all namespaces
$ kubectl get pods --all-namespaces -o jsonpath='{.items[*].spec.containers[*].image}'
# add a new line to the result
$ kubectl get pods --all-namespaces -o jsonpath='{.items[*].spec.containers[*].image}{"\n"}'
# ?() define filter
# @ - the current object
$ kubectl get nodes -o jsonpath="{.items[*].status.addresses[?(@.type=='InternalIP')].address}"
# sorting
$ kubectl get pods -A -o jsonpath='{.items[*].metadata.name}{"\n"}' --sort-by=.metadata.name
