Team, I need to delete 10s of pods on k8s cluster that has error. I am getting them as below:
kubectl get pods --all-namespaces | grep -i -e Evict -e Error | awk -F ' ' '{print $1, $2, $4}'
test-asdfasdf asdfasdf2215251 Error
test-asdfasdf asdfasdf2215252 Error
test-asdfasdf asdfasdf2215253 Error
test-asdfasdf asdfasdf2215254 Error
test-asdfasdf asdfasdf2215255 Error
test-asdfasdf asdfasdf2215256 Errormanually am deleting them like this:
kubectl delete pod asdfasdf2215251 -n test-asdfasdfbut can I write a script that just looks for error on any pod and deletes all of them? I am working on script myself but new to this hence getting late..
Start point:
kubectl get pods --all-namespaces |
grep -i -e Evict -e Error |
awk -F ' ' '{print $1, $2}' |will produce a stream of:
test-asdfasdf asdfasdf2215251
test-asdfasdf asdfasdf2215252
test-asdfasdf asdfasdf2215253
test-asdfasdf asdfasdf2215254
test-asdfasdf asdfasdf2215255
test-asdfasdf asdfasdf2215256we can go here:
while IFS=' ' read -r arg1 arg2; do
kubectl delete pod "$arg2" -n "$arg1"
donewe can go here:
xargs -l1 -- sh -c 'kubectl delete pod "$2" -n "$1"' --or use parallel or any kind of other tools to do that.
