k8s集群pod资源状态显示Terminating或Unknown时无法删除和故障排除

问题描述：

在k8s集群中利用yaml创建pod资源时，创建的资源显示为Terminating或Unknown

[root@master test]# kubectl get pods
NAME                              READY   STATUS        RESTARTS   AGE
my-tomcat-57667b9d9-nklvj         1/1     Terminating   0          10h
my-tomcat-57667b9d9-wllnp         1/1     Terminating   0          10h

解决方案：

使用强制删除命令：

kubectl delete pod [pod name] --force --grace-period=0 -n [namespace]

[root@localhost demo]# kubectl delete pod my-tomcat-57667b9d9-nklvj --force --grace-period=0 -n default
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 "my-tomcat-57667b9d9-nklvj" force deleted
[root@localhost demo]# kubectl delete pod my-tomcat-57667b9d9-wllnp --force --grace-period=0 -n default
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 "my-tomcat-57667b9d9-wllnp" force deleted

故障排除：

查看pod事件
kubectl describe TYPE NAME_PREFIX

查看pod日志（Failed状态下）
kubectl logs POD_NAME

进入pod（状态为running，但是服务没有提供）
kubectl exec –it POD_NAME bash
