k8s安装prometheus

根据自己的k8s版本下载prometheus，我的是1.23

git clone -b v0.10.0 https://github.com/prometheus-operator/kube-prometheus.git

查看需要单独下载的镜像，从hub.docker.com上自己查找下同样版本的镜像，下载完后改下yaml文件image

grep image ./* | grep k8s.
docker pull bitnami/kube-state-metrics:2.3.0
docker pull rgwrgw555/prometheus-adapter:v0.9.1
vim ./kubeStateMetrics-deployment.yaml
vim ./prometheusAdapter-deployment.yaml

部署

cd kube-prometheus
kubectl apply --server-side -f manifests/setup
kubectl create -f .

修改Prometheus的Service为NodePort

vim prometheus-service.yaml 
apiVersion: v1
kind: Service

    app.kubernetes.io/instance: k8s
