我正在尝试创建一个部署在kubernetes上的kafka集群。我有以下配置：
Kafka服务：

apiVersion: v1
kind: Service
metadata:
  name: kafka
  labels:
    app: kafka
  namespace: kafka
spec:
  ports:
  - name: kafka-port
    port: 9093
    protocol: TCP
  selector:
    app: kafka
  type: NodePort

Kafka全集：

apiVersion: apps/v1

  name: kafka
  namespace: kafka
  labels:
    app: kafka

Zookeeper服务：

zookeeper部署：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: zookeeper
  namespace: kafka
spec:
  replicas: 1
  template:
    metadata:
      labels:
        name: zookeeper
    spec:
      containers:
      - env:
        - name: ZOOKEEPER_ID
          value: "1"
        - name: ZOOKEEPER_SERVER_1
          value: zookeeper
        name: zookeeper
        image: digitalwonderland/zookeeper
        ports:
        - containerPort: 2181

有了这个配置，一切都很好。但我想添加更多Kafka的复制品。如果尝试添加另一个复制副本，则会收到以下错误：

Error connecting to node kafka-1.kafka.kafka.svc.cluster.local:9093 (id: 1 rack: null) (org.apache.kafka.clients.NetworkClient)
java.io.IOException: Can't resolve address: kafka-1.kafka.kafka.svc.cluster.local:9093

我不知道“kafka-1.kafka.kafka.svc.cluster.local”是在哪里设置的，也不知道我能不能从那里得到。我可以看到一个解决方案是为每个pod创建一个服务，但是使用这种方法集群不容易扩展。
我可以配置我的kafka stateful在没有任何其他服务的情况下发现对方吗？
编辑：
只有一个副本的配置只能在集群中工作，如果我试图从外部访问代理，则会收到以下异常：

Can't resolve address: kafka-0.kafka.kafka.svc.cluster.local:9093

谢谢
