1 pods are unevictable from node eksctl

How to solve "1 pods are unevictable from node in eksctl".

I tried to delete the AWS EKS cluster with the eksctl command.

Problem: eksctl delete fail (pending, stuck, block)

eksctl delete cluster -f host.yaml

(Interrupt and terminate a pending eksctl command.) ctrl + c

Cause: ebs-csi-controller's pdb (poddisruptionbudget)

^C

k get pdb -A
NAMESPACE     NAME                 MIN AVAILABLE   MAX UNAVAILABLE   ALLOWED DISRUPTIONS   AGE
kube-system   ebs-csi-controller   N/A             1                 0                     5h32m

 

Solution:  delete pdb

k get pdb -A
NAMESPACE     NAME                 MIN AVAILABLE   MAX UNAVAILABLE   ALLOWED DISRUPTIONS   AGE
kube-system   ebs-csi-controller   N/A             1                 0                     5h32m

k delete pdb ebs-csi-controller -n kube-system
poddisruptionbudget.policy "ebs-csi-controller" deleted

 

Result: eksctl delete works well
