问题1：

问题描述：k8s中Terminating状态pod不能删除

[root@master ~]# kubectl get pods -n ms
NAME                      READY   STATUS        RESTARTS   AGE
portal-7895774cd7-vr5wg   0/1     Terminating   1          102m

解决方法：强制删除

[root@master ~]# kubectl delete pods portal-7895774cd7-vr5wg --grace-period=0 --force -n ms
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.
