kube-prometheus-stack

使用helm安装Prometheus

kube-prometheus-stack 20.0.1 · prometheus/prometheus-community (artifacthub.io)

步骤

  1. 加仓库
1
2
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
  1. 安装

查看版本

1
helm search repo kube-prometheus-stack -l

拉取chart,就用目前的最新版本吧

1
helm pull prometheus-community/kube-prometheus-stack --version 20.0.1

报错

以前不知道什么时候装的crd版本相对于当前最新的prometheus来说太老了

按照Readme里说的卸载

kubectl delete crd alertmanagerconfigs.monitoring.coreos.com
kubectl delete crd alertmanagers.monitoring.coreos.com
kubectl delete crd podmonitors.monitoring.coreos.com
kubectl delete crd probes.monitoring.coreos.com
kubectl delete crd prometheuses.monitoring.coreos.com
kubectl delete crd prometheusrules.monitoring.coreos.com
kubectl delete crd servicemonitors.monitoring.coreos.com
kubectl delete crd thanosrulers.monitoring.coreos.com

卸载后再次安装，ok
