问题描述
我一直在尝试使用来自Kafka-exporter的Metrics实施Kubernetes HPA. Hpa支持Prometheus，因此我们尝试将指标写入Prometheus实例.从那里开始，我们不清楚要执行的步骤.是否有一篇文章将对其进行详细说明?
I had been trying to implement Kubernetes HPA using Metrics from Kafka-exporter. Hpa supports Prometheus, so we tried writing the metrics to prometheus instance. From there, we are unclear on the steps to do. Is there an article where it will explain in details ?
我关注了 https://medium.com /google-cloud/kubernetes-hpa-autoscaling-with-kafka-metrics-88a671497f07
，我们使用了堆栈驱动程序，该实现的工作就像一个魅力.但是，我们正在努力进行内部设置，因为堆栈驱动程序需要用Prometheus代替
for same in GCP and we used stack driver, and the implementation worked like a charm. But, we are struggling in on-premise setup, as stack driver needs to be replaced by Prometheus
推荐答案
当我使用来自Kafka-exporter的Metrics实施Kubernetes HPA时，我遇到了一些挫折，可以解决以下问题:
When I implemented Kubernetes HPA using Metrics from Kafka-exporter I had a few setbacks which I solved doing the following:
- 我将kafka-exporter容器作为边车部署到了我的吊舱想扩大规模.我发现HPA可以缩放获得的吊舱指标来自.
-
我使用了注释，以使Prometheus从带有导出程序的容器中抓取指标.
- I deployed the kafka-exporter container as a sidecar to the pods Iwanted to scale. I found that the HPA scales the pod it gets themetrics from.
I used annotations to make Prometheus scrape the metrics from the pods with exporter.
然后，我验证了kafka-exporter指标已应用于Prometheus.如果不存在，您将无法继续前进.
Then I verified that the kafka-exporter metrics are getting to Prometheus. If it's not there you can't advance further.
