minikube 部署 prometheusoperator

1. 安装minikube

1.1 下载minikube，参考 https://minikube.sigs.k8s.io/docs/start/

1.2 下载virtualbx ， 参考 https://www.virtualbox.org/wiki/Downloads

1.3 启动时minikube , driver选择virtualbx

minikube start --driver=virtualbox

备注：driver选择docker时本地mac无法访问k8s内NodePort。

2. 安装helm

参考官网 https://helm.sh/docs/intro/install/

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

　　

3. 通过helm安装prometheus-operator

helm install --name prometheus-operator --set rbacEnable=true --namespace=monitoring stable/prometheus-operator

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

helm repo update

helm install prometheus-operator prometheus-community/kube-prometheus-stack

　　

byte@~ % kubectl --namespace default get pods -l "release=prometheus-operator"
NAME                                                     READY   STATUS    RESTARTS   AGE
prometheus-operator-kube-p-operator-57b7bf4676-5zfc2     1/1     Running   0          13m
prometheus-operator-kube-state-metrics-74dc78bb5-dg875   1/1     Running   0          13m
prometheus-operator-prometheus-node-exporter-gvtnj       1/1     Running   0          13m

　　

4. 修改访问类型为NodePort

kubectl edit svc prometheus-operator-grafana 

kubectl edit svc prometheus-operator-kube-p-alertmanager

kubectl edit svc prometheus-operator-prometheus

# type: ClusterIP 改为 type: NodePort

 

5. 访问dashboard
