使用prometheus-operator部署prometheus服务,并对外提供访问

先决条件: 已经部署好k8s

#这里我使用的版本是1.28.12
[root@prometheus-operator /zpf/prometheus/kube-prometheus/manifests]$kubectl version
Client Version: v1.28.12
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.28.12

安装git服务

#安装git服务,用于后面拉取prometheus代码
[root@prometheus-operator /zpf/prometheus/kube-prometheus/manifests]$yum install git -y

下载kube-prometheus 源代码

#说明一下这里默认拉取的是最新版本的代码版本.可以根据自己的k8s版本来获取对应的kube-prometheus代码版本

#拉取代码
[root@prometheus-operator /zpf/prometheus/kube-prometheus/manifests]$git clone https://github.com/prometheus-operator/kube-prometheus.git

 下面是部分兼容性示例图,

代码拉取完成后会有一个kube-prometheus目录以下是相关的源码内容.

setup

#这里的setup是一个目录

首先创建预置资源,注册相关的资源项目

#当前目录位置
[root@prometheus-operator /zpf/prometheus/kube-prometheus/manifests]$pwd
/zpf/prometheus/kube-prometheus/manifests
#创建注册相关资源
[root@prometheus-operator /zpf/prometheus/kube-prometheus/manifests]$kubectl create -f ./setup/
