Scraping Kubernetes metrics from standalone Prometheus Instance

[Sakthi Raam]

Hi All,

We have restrictions to deploy Prometheus inside Kubernetes environment due to shared infrastructure but we still need to scrape all the node/services/endpoints/pod level metrics using service discovery approach. When I checked almost all the posts in internet are referring to Prometheus inside the cluster or deployed as Prometheus operator.

If you have any reference links, examples or approach to achieve the above mentioned use case please do share it.

Thank You

Regards

Sakthi

Are you meaning that you want to host Prometheus outside of the cluster,
but monitor resources within it?

If so, that's perfectly possible. You will need to set the api_server
value in the Kubernetes SD as well as providing the correct
authentication details (and arrange for those on the cluster side)
