我试图在traefik后面配置kafka集群，但是我的生产者和客户机（在kubernetes之外）没有连接到引导服务器。他们一直在说：
“给定url中没有可解析的引导服务器”
实际上这里是traefik入口：

{
    "apiVersion": "extensions/v1beta1",
    "kind": "Ingress",
    "metadata": {
        "name": "nppl-ingress",
        "annotations": {
            "kubernetes.io/ingress.class": "traefik",
            "traefik.frontend.rule.type": "PathPrefixStrip"
        }
    },
    "spec": {
        "rules": [
            {
                "host": "" ,
                "http": {
                    "paths": [
                        {
                            "path": "/zuul-gateway",
                            "backend": {
                                "serviceName": "zuul-gateway",
                                "servicePort": "zuul-port"
                            }
                        },                      
                        {
                            "path": "/kafka",
                            "backend": {
                                "serviceName": "kafka-broker",
                                "servicePort": "kafka-port"
                            }

    }

我给Kafka消费者/生产者的是traefik的公共ip。下面是流程：[kafka producers/consumers]->traefik（作为负载均衡器公开）->[kafka cluster]
有什么解决办法吗？否则我想添加一个kafka rest代理(https://docs.confluent.io/current/kafka-rest/docs/index.html)但我认为这不是一个理想的解决方案。
