k8s配置多端口ingress

一、背景：公司k8s在阿里云内网，购买的阿里云的k8s服务，配置neo4j后，需要外网访问neo4j的7474端口，配置上ingress后，使用域名访问后，web界面还会从本地跳转到7687端口，然而在ingress中只有7474端口，所以访问web界面有问题

以下为neo4j的yaml文件

apiVersion: v1

二、经过查阅文档，做出了如下修改

1、kubectl edit service/nginx-ingress-lb -n kube-system

 2、kubectl edit configmap/tcp-services -n kube-system

 执行完以上两步即可
