Set up prometheus outside the K8 Cluster

Question

I wanted to set up monitoring of my K8 cluster using Prometheus but wanted to set that up outside my existing cluster. I have come across a lot of articles which specify how to do the set up inside the cluster but have not come across much (including stack overflow posts) which give a detail/step by step walk through of how we can do this outside the cluster.

I have only found one useful article so far listed below: https://www.linkedin.com/pulse/monitoring-kubernetes-prometheus-outside-cluster-steven-acreman

Does anyone have any docs in regards to this. Any tips would be appreciated! Thanks!

Answer 1

Use Prometheus federation . There are different use cases for federation. Commonly, it is used to either achieve scalable Prometheus monitoring setups or to pull related metrics from one service's Prometheus into another.

People are also using this way to monitor multiple clusters.

Take a look: prometheus-integration .
