Question

我在Kubernetes集群中部署了TICK stack以用于监视。我的应用程序将其自定义数据推送到它。

我尝试在Prometheus适配器的帮助下使用自定义指标进行水平pod自动缩放。我很好奇是否也有针对InfluxDB的适配器？

流行的Kubernetes custom metrics adapters不包括InfluxDB。有没有一种方法可以使用我现有的基础结构（包含InfluxDB）通过应用程序中的自定义指标自动缩放Pod？

Answer 1

为什么不将Prometheus的自定义指标与influxdb-exporter一起使用？我不明白为什么它不起作用。

It is possible to use influxdb with heapster, in attachments some files that I set up to use in an easy way.
First run influxdb.yaml
Run second heapster-rbac.yaml
Third run heapster.yaml

**INFLUXDB.YAML**

Answer 3

InfluxDB可以与Heapster一起使用（由@LucasSales指出），但在当前版本的Kubernetes中已弃用。
对于最新版本的Kubernetes，我们具有用于基本CPU /内存指标的指标服务器。 Prometheus是公认的第三方监视工具，尤其是对于自定义指标等。

使用InfluxDB使用自定义指标进行水平Pod自动缩放
