Delete evicted pods

gistfile1.txt

kubectl get pods | grep Evicted | awk '{print $1}' | xargs kubectl delete pod

kubectl get po -A --all-namespaces -o json | jq  '.items[] | select(.status.reason!=null) | select(.status.reason | contains("Evicted")) | "kubectl delete po \(.metadata.name) -n \(.metadata.namespace)"' | xargs -n 1 bash -c

Thank you!

i think the most simple command is kubectl delete pods -A --field-selector=status.phase=Failed

Works for me too, for deleting failed pods in all namespaces

Did you know that you can use the --field-selector option for kubectl delete as well?

kubectl delete pod --field-selector="status.phase==Failed"

Great answer, thanks!

Why doesn't Kubernetes clean up Evicted pods by itself? I only notice it happen sometimes.

My understanding is that there is a threshold for cleaning up - when the number of failed hits that threshold then clean up will happen - the challenge is that the default for that is 12500 (twelve thousand five hundred). The purpose of the threshold is to allow for review of the reasons for failure and I can see that in a large system that might almost be a reasonable number.

That threshold can be changed - I'm not sure what a sensible number would look like for a small cluster.

kubectl get pod -A | grep Evicted | awk '{print $2 " --namespace=" $1}' | xargs -n 2 kubectl delete pod

work for me
