一、验证网络连通性——配置网络策略——验证宿主机下端口是否通信

### --- 验证mysql端口是否通信
~~~     mysql端口已经不能正常通信，说明networkpolicy已经生效

[root@k8s-master01 ~]# kubectl get po -n nw-demo -owide
NAME                     READY   STATUS              RESTARTS   AGE    IP              NODE           NOMINATED NODE   READINESS GATES
redis-c9fdb57d5-4wd78    1/1     Running             0          129m   172.17.125.14   k8s-node01     <none>           <none>
[root@k8s-master01 ~]# telnet 172.25.92.115 3306

二、验证redis端口是否通信

### --- 验证redis端口是否通信
~~~     redis端口已经不能正常通信，说明networkpolicy已经生效

[root@k8s-master01 ~]# kubectl get po -n nw-demo -owide
NAME                     READY   STATUS              RESTARTS   AGE    IP              NODE           NOMINATED NODE   READINESS GATES
redis-c9fdb57d5-4wd78    1/1     Running             0          129m   172.17.125.14   k8s-node01     <none>           <none>
[root@k8s-master01 ~]# telnet  172.17.125.14 6379
