[root@lab3 ~]# kubectl delete deploy coredns -n kube-system --now

[root@lab3 ~]# kubectl delete deploy coredns -n kube-system --grace-period=0 --force


kubectl delete rc kube-dns-v20 --force=true --grace-period=0 --namespace=kube-system


然後重啟這個pod對應的node上的docker


實在不行，重啟這三臺



重啟不管用  就改下delpoment的名字重新創建




[root@node2 
 
~]# kubectl delete pods monitoring-grafana-5cc566546-mnh2c --grace-period=0 --force -n kube-system
warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely.
pod "monitoring-grafana-5cc566546-mnh2c
 
" force deleted



註意上面已經打印出了警告，意思是說刪除的Pod相關的容器有可能成為孤兒永遠的運行在集群上，

因此在刪除之前可以查看一下Pod跑在哪個Node上，在強制刪除Pod之後，可以到對應的Node上將docker容器手動停掉。

刪除deploy
