当我部署好elasticsearch的服务后由于个人习惯一般服务会在name里带上svc所以我elasticsearch服务的名字是elasticsearch-svc
[rootmaster ~]# kubectl get svc -n kube-logging31
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
elasticsearch-svc ClusterIP None none 9200/TCP,9300/TCP 10h
kibana-svc NodePort 10.105.0.72 none 5601:31231/TCP 14m但是当我部署好elasticsearch和kibana后发现kibana无法连接到elasticsearch查看kibana pod的日志发现如下报错
{type:log,timestamp:2024-10-02T13:24:30Z,tags:[warning,elasticsearch,admin],pid:1,message:No living connections}
{type:log,timestamp:2024-10-02T13:24:30Z,tags:[warning,elasticsearch,admin],pid:1,message:Unable to revive connection: http://elasticsearch:9200/}
这里说kibana试图连接到elasticsearch:9200。随后进入kibana的pod进行验证
[rootmaster 31efk]# kubectl exec -it kibana-deploy-6bc6b7cd49-z7rzh -n kube-logging31 -- sh
sh-4.2$ curl -v http://elasticsearch-svc:9200
* About to connect() to elasticsearch-svc port 9200 (#0)
* Trying 10.244.104.12...

sh-4.2$ exit
exit发现在kibana内部可以成功解析elasticsearch-svc。
定位到问题可能是kibana的默认elasticsearch服务的配置是elasticsearch9200。
[rootmaster 31efk]# kubectl exec -it kibana-deploy-6bc6b7cd49-z7rzh -n kube-logging31 -- cat /usr/share/kibana/config/kibana.yml
#
# ** THIS IS AN AUTO-GENERATED FILE **
## Default Kibana configuration for docker target
server.name: kibana
server.host: 0
elasticsearch.hosts: [ http://elasticsearch:9200 ]可以看到默认的hosts就是 [ http://elasticsearch:9200 ]。
所以解决办法是在kibana的deployment文件里增加下面环境变量一开始只有ELASTICSEARCH_URL
env:- name: ELASTICSEARCH_HOSTSvalue: http://elasticsearch-svc:9200
