helm 安装prometheus operator 并监控ingress

1.helm安装

curl https://raw.githubusercontent.com/helm/helm/master/scripts/get > get_helm.sh
chmod 700 get_helm.sh
./get_helm.sh
helm init --history-max 200
helm repo update
helm install stable/mysql
helm ls
kubectl -n kube-system create serviceaccount tiller
kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
helm init --upgrade
helm ls
kubectl --namespace kube-system patch deploy tiller-deploy -p '{"spec":{"template":{"spec":{"serviceAccount":"tiller"}}}}'
helm list
helm repo update

2.安装ingress

helm install stable/nginx-ingress --name my-release     --set controller.stats.enabled=true,controller.kind=DaemonSet,controller.daemonset.useHostPort=true,controller.publishService.enabled=true,controller.service.externalTrafficPolicy=Local,controller.service.type=NodePort,controller.stats.enabled=true,controller.metrics.enabled=true  helm安装最好用value文件更新要不然会抵消上一个版本的值。

3.安装prometheus operator

helm install stable/prometheus-operator

4.配置servicemonitors.monitoring.coreos.com

[root@iZrj969udf3fibvyz4dlieZ ~]# kubectl get servicemonitors.monitoring.coreos.com nginx-ingress-controller-metrics -oyaml
