【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。其他人遇到这个问题吗？

【问题讨论】：

看起来你有一个 python sidecar。你有 grafana 的部署/pod 定义吗？

是的，pod 中有三个容器。 kiwigrid/k8s-sidecar:0.0.3 kiwigrid/k8s-sidecar:0.0.3 grafana/grafana:5.3.1

你用什么来安装这个的？我跟随的指南没有边车

helm install stable/prometheus-operator

【参考方案1】：

基于Prometheus operator repository... 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...您可以检查 Grafana 容器日志中的 Grafana 容器吗？

【讨论】：

Grafana 容器的日志显示正常，我可以在浏览器中查看仪表板。吊舱重新启动也已趋于平稳。在最初的 12 个小时左右有 280 个，之后就没有了。仪表板似乎正在工作，但有点令人不安的是，我仍然在原始问题中看到边车容器的日志中出现故障。

【参考方案2】：

这可以通过更新到更新版本的边车容器来修复，因为它是一个已修复的已知错误
