我正在尝试让 prometheus 在我在 VM 上设置的 Kube 集群上运行。
helm install monitor prometheus-community/prometheus -n monitoring -f ./values.yaml
然后我得到
NAME READY STATUS RESTARTS AGE

进一步挖掘我发现有人试图通过创建初始化容器来修复 /data https://github.com/prometheus/prometheus/issues/5976
但是由于我试图通过 helm 完成所有工作，并且我开始了解到它不是一些可以添加其他内容的可配置 kustomize 之类的东西。
