今天想要把 Prometheus 的 Helm chart 抓下來使用，

簡單記錄一下步驟吧～

首先加入 Prometheus 的 Helm repo：

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update

接著可以搜尋一下 repo 裡有哪些 Helm chart：

$ helm search repo prometheus-community
NAME                                              	CHART VERSION	APP VERSION	DESCRIPTION

prometheus-community/jiralert                     	1.4.1        	v1.3.0     	A Helm chart for Kubernetes to install jiralert
prometheus-community/kube-prometheus-stack        	47.3.0       	v0.66.0    	kube-prometheus-stack collects Kubernetes manif...

prometheus-community/prometheus                   	22.7.0       	v2.45.0    	Prometheus is a monitoring system and time seri...
prometheus-community/prometheus-adapter           	4.2.0        	v0.10.0    	A Helm chart for k8s prometheus adapter
......

像我要抓的是 prometheus 這個 helm chart ，就執行下面的指令：

helm pull prometheus-community/prometheus

抓下來是 prometheus-22.7.0.tgz 這個檔案，

解開後就可以使用囉～
