How to delete pending pods in kubernetes?

Question

I have two pending pods which I cannot delete by any means. Could you help? OS: Cent OS 7.8 Docker: 1.13.1 kubenetes: "v1.20.1"

[root@master-node ~]# k get pods --all-namespaces    (note: k = kubectl alias)
NAMESPACE              NAME                                         READY   STATUS    RESTARTS   AGE
**default                happy-panda-mariadb-master-0                 0/1     Pending**   0          11m
**default                happy-panda-mariadb-slave-0                  0/1     Pending**   0          49m

I already tried delete by various ways but nothing worked (I also tried to delete from the dashboard)

**kubectl delete pod happy-panda-mariadb-master-0 --namespace="default"
k delete deployment mysql-1608901361
k delete pod/happy-panda-mariadb-master-0 -n default --grace-period 0 --force**

Could you advise me on this?

Answer 1

kubectl delete rc replica set names

Or You forgot to specify storageClassName: manual in PersistentVolumeClaim.

Answer 2

You should delete the statefulset which controls the pods instead of deleting the pods directly. The reason pods are not getting deleted is because statefulset controller is recreating them after you delete it.

kubectl delete statefulset happy-panda-mariadb-master
