k8s之 kube-prometheus监控
Kubernetes 中的 kube-prometheus 是一个基于 Prometheus Operator 的完整监控办理方案，它集成了 Prometheus、Alertmanager、Grafana 以及一系列预界说的监控规则和仪表盘，专为 Kubernetes 集群设计。一、核心组件先容
[*]Prometheus Operator ：用于自动化管理 Prometheus 及其相关资源（如 ServiceMonitor、PodMonitor、PrometheusRule）
[*]Prometheus：负责指标采集、存储和告警规则的评估
[*]Alertmanager：处理 Prometheus 发送的告警，进行分组、去重、静默和关照（如邮件）
[*]Grafana：提供预配置的监控仪表盘，可视化集群和应用指标
[*]预界说监控规则：包罗 Kubernetes 核心组件（API Server、kubelet、etcd 等）的告警规则和仪表盘配置
二、NFS存储摆设
1.下载安装nfs和rpcbind
#yum -y install nfs-utils
# mkdir -p /ifs/kubernetes
# chmod -R 777 /ifs/kubernetes
# vim /etc/exports
/ifs/kubernetes *(rw,no_root_squash,sync)
#作为NFS的依赖服务，协调客户端与服务器端的通信
# yum -y install rpcbind
2.启动
# systemctl enable --now rpcbind
# systemctl enable --now nfs 3.测试nfs
#使配置生效
# exportfs -f
# showmount -e 192.168.91.19
Export list for 192.168.91.19:
/ifs/kubernetes *
#所有node查看nfs是否可以看到
# showmount -e 192.168.91.19
Export list for 192.168.91.19:
/ifs/kubernetes * 4.摆设动态存储
#下载相关安装包

#导入镜像
# docker load -i nfs-client-provisioner.tar.gz
#部署存储
# unzip nfs.zip
Archive:nfs.zip
inflating: pvc.yaml
inflating: nfs-class.yaml
inflating: nfs-deployment.yaml
inflating: nfs-rabc.yaml
# ll

#修改nfs的ip地址为自己的nfs地址额
# sed -i 's/192.168.91.18/192.168.91.19/g' nfs-deployment.yaml
# kubectl apply -f .

三、摆设监控体系
1.下载镜像和yaml文件
#1.下载
https://pan.baidu.com/s/1wTyT8DqH7_tS6wEWYFxVng?pwd=r6a5
#2.解压
# tar xf monitor.1.23.tar.gz
# cd monitor/serviceMonitor
#3.查看k8s组件ip是否正确，根据情况修改
# ls | xargs grep 192.168.91
prometheus-EtcdService.yaml:- ip: 192.168.91.18
prometheus-EtcdService.yaml:- ip: 192.168.91.19
prometheus-EtcdService.yaml:- ip: 192.168.91.20
prometheus-kubeControllerManagerService.yaml:- ip: 192.168.91.18
prometheus-kubeControllerManagerService.yaml:- ip: 192.168.91.19
prometheus-kubeControllerManagerService.yaml:- ip: 192.168.91.20
prometheus-KubeProxyService.yaml:- ip: 192.168.91.21
prometheus-KubeProxyService.yaml:- ip: 192.168.91.22
prometheus-kubeSchedulerService.yaml:- ip: 192.168.91.18
prometheus-kubeSchedulerService.yaml:- ip: 192.168.91.19
prometheus-kubeSchedulerService.yaml:- ip: 192.168.91.20 2. 创建资源
#crd资源对象 prometheus-operator
#kubectl create -f setup/
#监控
#kubectl apply -f alertmanager/
#节点的资源
#kubectl apply -f node-exporter/
#容器的资源使用率
#kubectl apply -f kube-state-metrics/
#可视化界面
#kubectl apply -f granfa/
#
#kubectl apply -f prometheus/
#kubectl apply -f serviceMonitor/
# kubectl get pods -n monitoring
NAME READY STATUS RESTARTS AGE
alertmanager-main-0 2/2 Running 0 39m
alertmanager-main-1 2/2 Running 0 39m
alertmanager-main-2 2/2 Running 0 39m

prometheus-k8s-1 2/2 Running 0 38m
prometheus-operator-f59c8b954-vqbwg 2/2 Running 0 39m 3.办理pvc绑定问题
# vim /etc/kubernetes/cfg/kube-apiserver.cfg
添加添加- --feature-gates=RemoveSelfLink=false
# systemctl restart kube-apiserver 5.查察地址并访问
#grafana
# kubectl get pod -A -o wide| grep grafana
monitoring grafana-f44f5bd49-9zxtg 1/1 Running 0 39m 172.17.14.8 node-2 <none> <none>
# kubectl get svc -A | grep grafana
monitoring grafana NodePort 10.0.0.36 <none> 3000:38801/TCP 40m
#页面访问并导入etcd和node-exporter模板
http://192.168.91.22:38801/
用户与密码: admin/admin
#访问prometheus
# kubectl get svc -A| grep prometheus-k8s
monitoring prometheus-k8s NodePort 10.0.0.166 <none> 9090:49004/TCP,8080:34712/TCP 69m
