Question

我正在尝试使用位于https://github.com/kubernetes/charts/tree/master/stable/prometheus的默认prometheus掌舵图将Prometheus安装到我的EKS集群中。它已成功部署，但是在Kubernetes仪表板中，AlertManager和Server部署显示：

pod具有未绑定的PersistentVolumeClaims（重复了3次）

我尝试修补values.yaml文件无济于事。

我知道这没什么大不了的，但是我真的不确定在日志记录方面还能找到什么。

这是运行helm install stable/prometheus --name prometheus --namespace prometheus

的输出

NOTES:
The Prometheus server can be accessed via port 80 on the following DNS name from within your cluster:
prometheus-server.prometheus.svc.cluster.local


Get the Prometheus server URL by running these commands in the same shell:
  export POD_NAME=$(kubectl get pods --namespace prometheus -l "app=prometheus,component=server" -o jsonpath="{.items[0].metadata.name}")
  kubectl --namespace prometheus port-forward $POD_NAME 9090


The Prometheus alertmanager can be accessed via port 80 on the following DNS name from within your cluster:
prometheus-alertmanager.prometheus.svc.cluster.local


Get the Alertmanager URL by running these commands in the same shell:
  export POD_NAME=$(kubectl get pods --namespace prometheus -l "app=prometheus,component=alertmanager" -o jsonpath="{.items[0].metadata.name}")
  kubectl --namespace prometheus port-forward $POD_NAME 9093


The Prometheus PushGateway can be accessed via port 9091 on the following DNS name from within your cluster:
prometheus-pushgateway.prometheus.svc.cluster.local


Get the PushGateway URL by running these commands in the same shell:
  export POD_NAME=$(kubectl get pods --namespace prometheus -l "app=prometheus,component=pushgateway" -o jsonpath="{.items[0].metadata.name}")
  kubectl --namespace prometheus port-forward $POD_NAME 9091

结果是，未在启用任何持久性存储的情况下创建EKS集群：

Amazon EKS集群未使用任何存储类创建。你必须定义要用于群集的存储类，并且应该定义一个持久卷声明的默认存储类。

This guide解释了如何为EKS添加kubernetes StorageClass

按照说明添加StorageClass，使用helm delete prometheus --purge删除我的Prometheus部署并重新创建部署之后，我的所有Pod现在都可以正常使用。

使用Helm安装Prometheus时出现永久性卷错误
