场景：

1、有多套环境

2、多套环境之间做了网络隔离

3、在环境1部署了etcd和kafka

4、想要在其它环境连接到环境1的etcd和kafka

方案：

1、分别申请vip指向etcd和kafka 的realserver ip和端口

2、开通其余环境到vip的网络策略

结果：

1、etcd成功

2、kafka-producer在建立连接的时候成功，发送数据的时候失败：

[root@xixixi kafka_2.13-2.6.0]# bin/kafka-console-producer.sh --bootstrap-server vip:9092 --topic test
