创建集群访问入口

创建服务定义vim zookeeper-access-service.yaml

apiVersion: v1
kind: Service
metadata:
  name: zookeeper34-access-service
  labels:
    name: zookeeper34-access-service
spec:
  selector:
    app: zookeeper34
  type: NodePort
  ports:
  - name: client
    targetPort: 2181
    port: 2181
    nodePort: 30811

执行创建服务：kubectl create -f zookeeper-access-service.yaml
查看服务：kubectl get svc

访问集群

如本地已安装zookeeper客户端，使用以下命令：
./zkCli.sh -server localhost:30811
测试创建节点：
create -e /test222 eee
get /test222
