Kubernetes sort pods by age

I can sort my Kubernetes pods by name using:

kubectl get pods --sort-by=.metadata.name

How can I sort them (or other resoures) by age using kubectl?

Solution

  • 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:

    1. kubectl get po --sort-by='{.firstTimestamp}'.
    2. kubectl get pods --sort-by=.metadata.creationTimestamp Thanks @chris

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