問題描述

我正在嘗試使用 Istio 示例插件安裝 Prometheus 和 Kiali。 我修改了文件，為 Service 添加了 nodePort，並將 Kiali 容器的 imagePullPolicy 更改為 IfNotPresent。 吊艙出現，但我無法查看圖表。 它給出了以下錯誤：

ERR invalid character '}' looking for beginning of object key string: goroutine 20932

Kiali pod 提供以下堆棧跟蹤：

invalid character '}' looking for beginning of object key string

如果LoadBalancer沒有特別的原因，我建議將這些清單恢復為 Istio 提供的原始清單。

如果您想訪問儀表板，您可以通過發出

istioctl dashboard kiali

對於 Kiali，或

istioctl dashboard promtheus

為普羅米修斯。

您可以選擇使用 Istio Gateway和VirtualService公開這些儀表板。 更多詳細信息可在此處獲得。

但是，我不建議將 Kiali 和 Prometheus 暴露在外部，因為它會帶來巨大的安全風險。
