Kubernetes sort pods by age

If you are trying to get the most recently created pod you can do the following

kubectl get pods --sort-by=.metadata.creationTimestamp -o jsonpath='{.items[-1:].metadata.name}'

Note the -1: gets the last item in the list, then we return the pod name

Pods have status, which you can use to find out startTime.

I guess something like kubectl get po --sort-by=.status.startTime should work.

You could also try:

Also apparently in Kubernetes 1.7 release, sort-by is broken.
