kubernetes - helm install 后 Grafana pod 不断重启

问题描述

我有一个干净的 AKS 集群，我部署了 prometheus-operator 图表。Grafana pod 显示了大量的重新启动。我的集群版本是 1.11.3。Grafana 日志如下。还有其他人遇到这个问题吗？

File in configmap grafana-dashboard-k8s-node-rsrc-use.json ADDED

解决方案

基于Prometheus 操作员存储库... Grafana pod 上的 sidecar 容器无法联系 Grafana 并重新加载/刷新正在监视的 configmap 上定义的仪表板。

所以这是 Grafana 容器失败的症状......你能检查 Grafana 容器日志中的 Grafana 容器吗？
