kubernetes新手篇-pod删除失败

问题发现

在删除pod时, 有时候会发现pod被删除了, 但是又会自动重建

[root@k8s-master01 ~]# kubectl get pods

# 为什么这些pod删除不掉

检查发现,是因为之前设定的副本数量, 删除pod控制器

[root@k8s-master01 ~]# kubectl get deployment myapp3
NAME     READY   UP-TO-DATE   AVAILABLE   AGE
myapp3   10/10   10           10          11h

[root@k8s-master01 ~]# kubectl get pods
No resources found.
# 发现这些pod成功被删除了
