Question

我有一个正在运行的elasticsearch集群，我正在尝试将kibana连接到此集群（同一节点）。当我尝试使用以下命令在浏览器中打开服务时，页面会挂起：。。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"}

安装在kibana pod中的我的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

我的elasticsearch.yml文件有以下配置设置（我有3个es pods）

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"]

我觉得问题目前在network.host字段，但我不确定。如果它们位于同一个群集/节点中，我需要修改哪些字段以便连接到kibana pod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上公开了Elasticsearch，但是正在尝试连接到kibana.yml文件中的端口9300。

您需要编辑要使用的kibana.yml文件：

elasticsearch.url: http://elasticsearch:9200

或者将elasticsearch服务中的端口更改为9300。

将kibana连接到kubernetes集群中的elasticsearch
