How to delete all evicted pods from all namespaces?

delete-all-evicted-pods.sh

#!/bin/bash

# This script is for Mac OSX users. If you are on Linux, replace 'gxargs' with 'xargs'.
# To install 'gxargs' command using Homebrew, run 'brew install findutils' first.

# Without parallel (ideal for small number of pods)
kubectl get pods --all-namespaces | grep Evicted | awk '{print $2 " --namespace=" $1}' | gxargs -n 1 -d '\n' bash -c 'kubectl delete pod $0 $1'

# With parallel (ideal for big number of pods)
# To install 'parallel' command using Homebrew, run 'brew install parallel' first.
# To install 'parallel' command on Linux (e.g. Ubuntu), refer https://askubuntu.com/a/298598/972977 for instructions.
kubectl get pods --all-namespaces | grep Evicted | awk '{print $2 " --namespace=" $1}' | gxargs -n 1 -d '\n' bash -c 'echo kubectl delete pod $0 $1' | parallel
