grafana部署配置测试

grafana官网地址

1.helm部署grafana

部署很简单,见下

[root@k8s-node1 prometheus-grafana]# helm install stable/grafana --generate-name NAME: grafana-1577432108 LAST DEPLOYED: Fri Dec 27 15:35:11 2019 NAMESPACE: default STATUS: deployed REVISION: 1 NOTES: 1. Get your 'admin' user password by running: kubectl get secret --namespace default grafana-1577432108 -o jsonpath="{.data.admin-password}" | base64 --decode ; echo 2. The Grafana server can be accessed via port 80 on the following DNS name from within your cluster: grafana-1577432108.default.svc.cluster.local Get the Grafana URL to visit by running these commands in the same shell: export POD_NAME=$(kubectl get pods --namespace default -l "app=grafana,release=grafana-1577432108" -o jsonpath="{.items[0].metadata.name}") kubectl --namespace default port-forward $POD_NAME 3000 3. Login with the password from step 1 and the username: admin ################################################################################# ###### WARNING: Persistence is disabled!!! You will lose your data when ##### ###### the Grafana pod is terminated. ##### #################################################################################

注意这条:

1. Get your 'admin' user password by running: kubectl get secret --namespace default grafana-1577432108 -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

服务起来了

[root@k8s-node1 ~]# kubectl get svc,pod |grep grafana service/grafana-1577432108 ClusterIP 10.254.172.86 <none> 80/TCP 132m pod/grafana-1577432108-65b987fdc6-dlhpb 1/1 Running 1 132m

2.配置web访问

配置Ingress文件,读取执行,然后做host解析即可通过grafana-server访问web.

[root@k8s-node1 prometheus-grafana]# cat grafana-server-ingress.yaml apiVersion: extensions/v1beta1 kind: Ingress metadata: name: grafana-server namespace: default spec: rules: - host: grafana-server http: paths: - path: / backend: serviceName: grafana-1577432108 servicePort: 80

3.登录

看前面第1部的注意,登录密码通过那个提示来获取.

[root@k8s-node1 prometheus-grafana]# kubectl get secret --namespace default grafana-1577432108 -o jsonpath="{.data.admin-password}" | base64 --decode ; echo sLJq2G4tBSiJcEHSobRoRiDRbCNXxT5qASQJkzF6

用户名是:admin
密码是:sLJq2G4tBSiJcEHSobRoRiDRbCNXxT5qASQJkzF6

登录成功,图示见下:

4.添加数据源

添加prometheus源

http url是prometheus service的地址

[root@k8s-node1 prometheus-grafana]# kubectl get svc |grep server prometheus-1577263826-server ClusterIP 10.254.132.104 <none> 80/TCP 47h

保存配置.再点击dashboard.

再import,就可以看到图形界面了

5.选一个自己喜欢的想用的个性参数更多的界面

去grafana网站下载模板json文件导入即可.
