1、拉取helm charts
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm search repo prometheus-community --versions # 选你想要的版本
helm pull prometheus-community/kube-prometheus-stack --version 75.18.1 --untar
2、修改values文件
# values.yamlextraArgs:web.external-url: "http://prometheus.xwk.local" # Prometheus内部感知的对外访问URL，一定要添加不要漏了
···ingress：enabled: true # 开启ingressClassName: "traefik" # 改为自己的ingress类
···hosts:- prometheus.xwk.local # 添加访问地址
···persistentVolume:enabled: truestorageClass: "nfs-data" # 添加存储类
···
alertmanager:## If false, alertmanager will not be installed##enabled: truepersistence:size: 2GipodSecurityContext:runAsUser: 65534runAsNonRoot: truerunAsGroup: 65534fsGroup: 65534persistence: # 这个是原来values中没有的，需要自己添加进去，不然storage-prometheus-alertmanager-0会处于pending状态enabled: truestorageClass: "nfs-data"accessModes:- ReadWriteOncesize: 2Gi# 安装
[root@master-11 prometheus]# helm install -n prometheus prometheus -f values.yaml .
Release "prometheus" has been install. Happy Helming!
