kubectl does not support regular expressions for JSONpath output. The following command does NOT work:
$ kubectl get pods -o jsonpath='{.items[?(@.metadata.name=~/^test$/)].metadata.name}'
The following command achieves the desired result:
$ kubectl get pods -o json | jq -r '.items[] | select(.metadata.name | test("test-")).spec.containers[].image'
