文档目录

部署monitoring

在ingress-nginx官网deploy/monitoring目录下载相关yaml文件

[root@elasticsearch01 monitoring]# pwd
/k8s/yaml/ingress-nginx/monitoring
[root@elasticsearch01 monitoring]# ls
configuration.yaml  grafana.yaml  prometheus.yaml

使用kubectl部署prometheus和grafana容器pod

[root@elasticsearch01 monitoring]# kubectl create -f ./
configmap/prometheus-configuration created
deployment.extensions/grafana created
service/grafana created
role.rbac.authorization.k8s.io/prometheus-server created
serviceaccount/prometheus-server created
rolebinding.rbac.authorization.k8s.io/prometheus-server created
deployment.apps/prometheus-server created
service/prometheus-server created

查看对外暴露端口，服务以NoderPort方式对外提供服务 prometheus访问地址为：http://10.2.8.65:37941 grafana访问地址为：http://10.2.8.34:32358 以上服务也可以部署ingress服务，通过域名访问

[root@elasticsearch01 monitoring]# kubectl get pods,svc -n ingress-nginx -o wide|egrep "grafana|prome"
