将kibana连接到kubernetes集群中的elasticsearch

Question

我有一个正在运行的 elasticsearch 集群，我正在尝试将 kibana 连接到这个集群（同一节点）。目前，当我尝试使用 : 在浏览器中打开服务时，页面挂起。. 在我的 kibana pod 日志中，pod 中的最后几条日志消息是：

{"type":"log","@timestamp":"2017-10-13T17:23:46Z","tags":["listening","info"],"pid":1,"message":"Server running at http://0.0.0.0:5601"}
{"type":"log","@timestamp":"2017-10-13T17:23:46Z","tags":["status","ui settings","error"],"pid":1,"state":"red","message":"Status changed from uninitialized to red - Elasticsearch plugin is red","prevState":"uninitialized","prevMsg":"uninitialized"}
{"type":"log","@timestamp":"2017-10-13T17:23:49Z","tags":["status","plugin:ml@5.6.3","error"],"pid":1,"state":"red","message":"Status changed from yellow to red - Request Timeout after 3000ms","prevState":"yellow","prevMsg":"Waiting for Elasticsearch"}

我挂载到 kibana pod 中的 kibana.yml 文件具有以下配置：

server.name: kibana-logging
server.host: 0.0.0.0 
elasticsearch.url: http://elasticsearch:9300
xpack.security.enabled: false
xpack.monitoring.ui.container.elasticsearch.enabled: true 

并且我的 elasticsearch.yml 文件具有以下配置设置（我有 3 个 es pod）

cluster.name: elasticsearch-logs
node.name: ${HOSTNAME}
network.host: 0.0.0.0

bootstrap.memory_lock: false
xpack.security.enabled: false
discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.unicast.hosts: ["172.17.0.3:9300", "172.17.0.4:9300", "172.17.0.4:9300"]

我觉得问题目前出在该network.host领域，但我不确定。如果它们位于同一个集群/节点中，我缺少哪些字段/是否需要修改才能将 kibana pod 连接到 elasticsearch？谢谢！

ES服务：

apiVersion: v1
kind: Service
metadata:
  name: elasticsearch
  labels:
    component: elasticsearch
    role: master
spec:
  type: NodePort
  selector:
    component: elasticsearch
    role: master
  ports:
  - name: http
    port: 9200
    targetPort: 9200
    nodePort: 30303
    protocol: TCP

Kibana Svc

apiVersion: v1
kind: Service
metadata:
  name: kibana
  namespace: default
  labels:
    component: kibana
spec:
  type: NodePort
  selector:
    component: kibana
  ports:
  - port: 80
    targetPort: 5601
    protocol: TCP

编辑：在 kibana.yml 中将端口更改为 9200 后，这是我在尝试访问 kibana 时在最后的日志中看到的内容：

{"type":"log","@timestamp":"2017-10-13T21:36:30Z","tags":["listening","info"],"pid":1,"message":"Server running at http://0.0.0.0:5601"}

Answer 1

这里的问题是您在端口 9200 上暴露了 Elasticsearch，但正在尝试连接到 kibana.yml 文件中的端口 9300。

您需要编辑 kibana.yml 文件才能使用：

elasticsearch.url: http://elasticsearch:9200

或者将elasticsearch服务中的端口更改为9300。
