# delete all evicted pods from all namespaces
kubectl get pods --all-namespaces | grep Evicted | awk '{print $2 " --namespace=" $1}' | xargs kubectl delete pod

# delete all containers in ImagePullBackOff state from all namespaces
kubectl get pods --all-namespaces | grep 'ImagePullBackOff' | awk '{print $2 " --namespace=" $1}' | xargs kubectl delete pod

# delete all containers in ImagePullBackOff or ErrImagePull or Evicted state from all namespaces
kubectl get pods --all-namespaces | grep -E 'ImagePullBackOff|ErrImagePull|Evicted' | awk '{print $2 " --namespace=" $1}' | xargs kubectl delete pod

What should be the command to delete evicted pods from a given namespace?

@ntsh999 you can use the above command from @yeouchien. Just change --all-namespaces to -n your_namespace.

E.g.

kubectl get pods -n default | grep Evicted | awk '{print $2 " --namespace=" $1}' | xargs -I '{}' bash -c 'kubectl delete pods {}'

@ntsh999 you can use below command. This will delete both Evicted and Failed pods

kubectl get pods --namespace <your_namespace> --field-selector 'status.phase==Failed' -o json | kubectl delete -f -

What about this?

kubectl get pods -A --field-selector=status.phase!=Running --template '{{range .items}}kubectl delete pod -n {{.metadata.namespace}} {{.metadata.name}}{{"\n"}}{{end}}' | sh
