[英]Cluster Level Logging with Elasticsearch and Kibana does not work in kubernetes
[英]Connect kibana to elasticsearch in kubernetes cluster
我有一個正在運行的elasticsearch集群,我正在嘗試將kibana連接到此集群(同一節點)。 當我嘗試使用以下命令在瀏覽器中打開服務時,頁面會掛起:。 。 在我的kibana pod日志中,pod中的最后幾條日志消息是:
{"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"}
我在kibana pod中安裝的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
和我的elasticsearch.yml文件有以下配置設置(我有3個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"]
我覺得這個問題目前在network.host
字段,但我不確定。 如果它們位於同一個群集/節點中,我需要修改哪些字段以便連接到kibana pod到elasticsearch? 謝謝!
ES服務:
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
編輯:在kibana.yml中將端口更改為9200后,這是我在嘗試訪問kibana時在日志中看到的內容:
{"type":"log","@timestamp":"2017-10-13T21:36:30Z","tags":["listening","info"],"pid":1,"message":"Server running at http://0.0.0.0:5601"}
{"type":"log","@timestamp":"2017-10-13T21:36:30Z","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":"2017-10-13T21:36:33Z","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"}
{"type":"log","@timestamp":"2017-10-13T21:37:02Z","tags":["error","elasticsearch","admin"],"pid":1,"message":"Request error, retrying\nPOST http://elasticsearch:9200/.reporting-*/esqueue/_search?version=true => getaddrinfo ENOTFOUND elasticsearch elasticsearch:9200"}
{"type":"log","@timestamp":"2017-10-13T21:37:32Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
{"type":"log","@timestamp":"2017-10-13T21:37:33Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
{"type":"log","@timestamp":"2017-10-13T21:37:37Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
{"type":"log","@timestamp":"2017-10-13T21:37:38Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
{"type":"log","@timestamp":"2017-10-13T21:37:42Z","tags":["warning","elasticsearch","admin"],"pid":1,"message":"Unable to revive connection: http://elasticsearch:9200/"}
這里的問題是您在端口9200上公開了Elasticsearch,但是嘗試連接到kibana.yml文件中的端口9300。
您需要編輯您的kibana.yml文件才能使用:
elasticsearch.url: http://elasticsearch:9200
或者將elasticsearch服務中的端口更改為9300。
