部署Zookeeper集群

为什么部署kafka前要部署zookeeper？

Kafka依赖Zookeeper来实现分布式协调和配置管理。在Kafka集群中，Zookeeper扮演着多种角色，包括：

配置管理：Kafka集群的配置信息和元数据存储在Zookeeper中，包括主题（topics）、分区（partitions）、副本（replicas）等配置信息。

1. Leader选举：Kafka的分区（partitions）被分布式存储在集群中的多个Broker上，每个分区都有一个Leader和多个Follower。Zookeeper负责Leader选举，确保每个分区都有一个活跃的Leader。
2. Broker注册：Kafka Broker在启动时会向Zookeeper注册自己的信息，包括地址、ID等，以便其他Broker和客户端发现和连接。
3. 健康监测：Zookeeper监控Kafka集群中各个节点的健康状态，并在节点出现故障或宕机时触发相应的处理操作。

因此，在部署Kafka之前，需要先部署Zookeeper，确保Kafka集群正常运行所需的分布式协调和配置管理功能可用。没有Zookeeper，Kafka无法正常运行，并且无法实现高可用性、数据一致性和故障容错等特性。

创建命名空间

# 添加如下内容
apiVersion: v1
kind: Namespace
metadata:
  name: kafka

创建Service资源

创建集群内部访问的Service资源:

apiVersion: v1
kind: Service
metadata:
  name: zookeeper-cluster  #无头服务的名称，需要通过这个获取ip，与主机的对应关系
  namespace: kafka
  labels:
    app: zookeeper
spec:
  ports:
    - port: 2181
      name: zookeeper
    - port: 2188
      name: cluster1
    - port: 3888
      name: cluster2
  clusterIP: None   # 此类型的Service没有ip
  selector:
    app: zookeeper

创建NodePort类型的Service资源,通过主机暴漏端口访问

apiVersion: v1
kind: Service
metadata:

    - protocol: TCP
      port: 80        # Service 暴露的端口
      targetPort: 2181   # Pod 中容器的端口
      nodePort: 32181   # NodePort 类型的端口范围为 30000-32767，可以根据需要调整
      
apiVersion: v1
kind: Service

      nodePort: 32182   # NodePort 类型的端口范围为 30000-32767，可以根据需要调整
      
      
apiVersion: v1
kind: Service
metadata:
  name: zookeeper-nodeport-service-2
  namespace: kafka
spec:
  type: NodePort
  selector:
    statefulset.kubernetes.io/pod-name: zookeeper-2
  ports:
