如何删除 kubernetes 中的待处理 pod？

Question

我有两个挂起的 pod，我无法以任何方式删除它们。 你能帮忙吗？ 操作系统：美分操作系统 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

我已经尝试通过各种方式删除但没有任何效果（我也尝试从仪表板中删除）

**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**

你能给我建议吗？

Answer 1

kubectl 删除 rc 副本集名称

或者您忘记在 PersistentVolumeClaim 中指定 storageClassName: manual。

Answer 2

您应该删除控制 pod 的 statefulset，而不是直接删除 pod。 pod 没有被删除的原因是 statefulset controller 在您删除它后重新创建它们。

kubectl delete statefulset happy-panda-mariadb-master
