Prometheus监控K8S--通过kube-prometheus 1、安装之前，查看对应的版本信息
由于安装的是1.21版本所以需要下载release-0.9 2、下载对应的版本 https:///prometheus-operator/kube-prometheus
CSS git clone https:///prometheus-operator/kube-prometheus.git [root@k8s-master prometheus]# cd kube-prometheus [root@k8s-master kube-prometheus]# ls developer-workspace example.jsonnet experimental go.sum jsonnetfile.json kubescape-exceptions.json LICENSE manifests README.md scripts CHANGELOG.md CONTRIBUTING.md docs examples go.mod jsonnet jsonnetfile.lock.json kustomization.yaml Makefile nohup.out tests
3、安装
SQL 1、安装之前先导入镜像， [root@k8s-master images]# ll total 502752 -rw-r--r-- 1 root root 61165568 Apr 21 20:43 alertmanager.tar -rw-r--r-- 1 root root 285516288 Apr 21 20:43 grafana.tar -rw-r--r-- 1 root root 62647808 Apr 21 20:43 kube-rbac-proxy.tar -rwxr-xr-x 1 root root 205 Apr 21 20:46 -rw------- 1 root root 22312960 Apr 21 16:58 node-exporter.tar -rw-r--r-- 1 root root 69536256 Apr 21 20:43 prometheus-adapter.tar -rw-r--r-- 1 root root 13626368 Apr 21 20:43 prometheus-config-reloader.tar [root@k8s-master images]# sh
2、安装命令 kubectl create -f manifests/setup
3、待定前面的容器启动后执行 kubectl create -f manifests/
4、查看资源 [root@k8s-master ~]# kubectl get pod -nmonitoring -owide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES alertmanager-main-0 2/2 Running 0 159m 10.244.2.85 k8s-node2 <none> <none> alertmanager-main-1 2/2 Running 0 159m 10.244.3.101 k8s-node1 <none> <none> alertmanager-main-2 2/2 Running 0 159m 10.244.4.69 k8s-node6 <none> <none> blackbox-exporter-5cb5d7479d-5bvfh 3/3 Running 0 160m 10.244.2.83 k8s-node2 <none> <none> grafana-7ccd96765c-dzpqs 1/1 Running 0 160m 10.244.2.84 k8s-node2 <none> <none> kube-state-metrics-79f478884f-mckgc 3/3 Running 0 160m 10.244.4.67 k8s-node6 <none> <none> node-exporter-54zt8 2/2 Running 14 160m 172.16.4.169 node <none> <none> node-exporter-586pr 2/2 Running 10 160m 172.16.4.203 k8s-node2 <none> <none> node-exporter-bqcxx 2/2 Running 0 160m 172.16.4.121 k8s-node1 <none> <none> node-exporter-j2h6j 2/2 Running 14 160m 172.16.7.210 k8s-node6 <none> <none> prometheus-adapter-7bf7ff5b67-m9hnm 1/1 Running 0 160m 10.244.3.99 k8s-node1 <none> <none> prometheus-adapter-7bf7ff5b67-t8tct 1/1 Running 0 160m 10.244.3.100 k8s-node1 <none> <none> prometheus-k8s-0 2/2 Running 0 159m 10.244.2.86 k8s-node2 <none> <none> prometheus-k8s-1 2/2 Running 0 159m 10.244.4.70 k8s-node6 <none> <none> prometheus-operator-b998f8597-zq797 2/2 Running 0 160m 10.244.4.68 k8s-node6 <none> <none> 3、卸载
PowerShell kubectl delete --ignore-not-found=true -f manifests/ -f manifests/setup
4、通过web访问grafana
Apache nohub kubectl port-forward --address 0.0.0.0 svc/grafana 3000:3000 -n monitoring 5、在grafana里导入相关的dashboard 依次点击+ --> Import--导入相关的json文件
