如何将 Docker 中的 Prometheus 连接到 Kubernetes 集群？

Question

I am referring to this link ( https://github.com/vegasbrianc/prometheus ) to install Prometheus in Docker version into a Ubuntu server (server-1)

I also have a Kubernetes cluster (bare-metal) running in another Ubuntu server (server-2). In this Kubernetes cluster, I have some sample apps being deployed.

I know normally people will deploy Prometheus to the same Kubernetes cluster.

But now, I want to use this Prometheus in server-1 to monitor the apps in Kubernetes cluster in server-2. How to achieve this? Is there any setting/ configuration I have to do to achieve the monitoring?

假设两台服务器可以相互访问，您需要在 server-2 上配置 prometheus 以抓取在 server-1 上运行的目标，这反过来又必须以 server-2 可以访问的方式公开它们的/metrics路径（ via ingress 是最受欢迎的选择）。
