Prometheus相关地址信息Prometheus github 地址：~]# mkdir prometheus[root@k8s-master ~]# cd prometheus[root@k8s-master prometheus]# pwd/root/prometheus

将kube-prometheus传到/root/下[root@k8s-master ~]# cd /root/kube-prometheus/manifests

[root@k8s-master prometheus]# pwd/root/导入镜像kube-prometheus.git.tar.gz prometheus.tar.gz load-images.sh

[root@k8s-master prometheus]# tar -zvxf prometheus.tar.gzprometheus/prometheus/addon-resizer.tarprometheus/alertmanager.tarprometheus/configmap-reload.tarprometheus/grafana.tarprometheus/k8s-prometheus-adapter-amd64.tarprometheus/kube-rbac-proxy.tarprometheus/kube-state-metrics.tarprometheus/node-exporter.tarprometheus/prometheus-config-reloader.tarprometheus/prometheus-operator.tarprometheus/prometheus.tar

[root@k8s-master prometheus]# cat load-images.sh#!/bin/bash

cd /root/prometheus

ls /root/prometheus | grep -v load-images.sh > /tmp/k8s-images.txt

for i in $( cat /tmp/k8s-images.txt )dodocker load -i $idonerm -rf /tmp/k8s-images.txt

[root@k8s-master ~]# chmod a+x load-images.sh[root@k8s-master ~]# ./load-images.sh

传镜像给别的节点[root@k8s-master ~]# scp -r prometheus/ load-images.sh root@k8s-node1:/root/[root@k8s-master ~]# scp -r prometheus/ load-images.sh root@k8s-node2:/root/

别的节点导入镜像[root@k8s-node1 ~]# ./load-images.sh[root@k8s-node2 ~]# ./load-images.sh

回到主节点[root@k8s-master prometheus]# cd /root/kube-prometheus/manifests[root@k8s-master manifests]# kubectl apply -f ../manifests有报错的时候，多运行几次，因为需要互相连接，直到最后所有created没有报错为止。[root@k8s-master manifests]# kubectl apply -f ../manifests

[root@k8s-master manifests]# kubectl top nodeNAME CPU(cores) CPU% MEMORY(bytes) MEMORY% k8s-master 164m 8% 1019Mi 17% k8s-node1 104m 10% 859Mi 49% k8s-node2 109m 10% 858Mi 45%
