kubectl JSON and sort examples

get events sorted by counts and only some fields we're interested in

$ kubectl -n pubsub get ev --sort-by count -o custom-columns='NAME:.metadata.name,KIND:involvedObject.kind,MSG:.message,FIRST:firstTimestamp,COUNT:.count'

using go templating

$ kubectl get events  --sort-by='.metadata.creationTimestamp'  -o 'go-template={{range .items}}{{.involvedObject.name}}{{"\t"}}{{.involvedObject.kind}}{{"\t"}}{{.message}}{{"\t"}}{{.reason}}{{"\t"}}{{.type}}{{"\t"}}{{.firstTimestamp}}{{"\n"}}{{end}}'
