Question

我们计划在kubernetes上建立Kafka和zookeeper，Zookeeper正如预期的那样正常工作，但在设立Kafka时，kafka正在解决问题，Kafka无法与zookepeer沟通。我们计划设置内部负载均衡器以与外部世界进行通信，我们如何进行通信。请参考以下文件：

卡夫卡：

---
apiVersion: v1
kind: Service
metadata:
  name: kafka
  namespace: default
spec:
  ports:
  - port: 9092
  clusterIP:
  selector:
    app: kafka
---
apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
  name: broker
  namespace: default
spec:
  serviceName: "kafka"
  replicas: 1
  template:
    metadata:
      labels:

        env:
        - name: KAFKA_ZOOKEEPER_CONNECT
          value: "zookeeper:2181"
        - name: KAFKA_ADVERTISED_LISTENERS
          value: PLAINTEXT://broker-0.kafka.cp-quickstart.svc.cluster.local:29092
        ports:
        - containerPort: 9092

Zookeeper群集：

kind: Deployment
apiVersion: extensions/v1beta1

  name: zookeeper-deployment-31
spec:
  replicas: 1
  selector:
    matchLabels:

        name: zookeeper-31
    spec:
      containers:
      - name: zoo31
        image: confluentinc/cp-zookeeper
        ports:
        - containerPort: 2181
        env:
        - name: ZOOKEEPER_ID
          value: "3"
        - name: ZOOKEEPER_SERVER_11
          value: zoo11
        - name: ZOOKEEPER_SERVER_21
          value: zoo21
        - name: ZOOKEEPER_SERVER_31
          value: zoo31
        - name: ZOOKEEPER_INIT_LIMIT
          value: "5"
        - name: ZOOKEEPER_SYNC_LIMIT
          value: "2"
        - name: ZOOKEEPER_SNAP_COUNT
          value: "100000"
        - name: ZOOKEEPER_AUTOPURGE_SNAP_RETAIN_COUNT
          value: "10"
        - name: ZOOKEEPER_AUTOPURGE_PURGE_INTERVAL
          value: "24"
        - name: ZOOKEEPER_CLIENT_PORT
          value: "2181"

Zookeeper服务：

apiVersion: v1
kind: Service
metadata:
  name: zoo12
  labels:
    app: zookeeper-11
spec:
  ports:
  - name: client
    port: 2181
    protocol: TCP
  - name: follower
    port: 2888
    protocol: TCP
  - name: leader
    port: 3888
    protocol: TCP
  selector:
    app: zookeeper-11

Answer 1

- name: KAFKA_ZOOKEEPER_CONNECT

必须列出所有带有语法的zookeeper服务器：

statefullName.service

例如：zookeeper-0.zookeeper：2181

您不需要为zookeeper创建3个服务，每个有状态一个。一个就够了。

kafka和zookeper在kubernetes上设置
