Publish Prometheus metrics about build info #4576

pedro-stanaka · 2023-05-25T21:35:32Z

Summary

I am adding a new metric that I missed while doing my monitoring setup for Keda. This new metric will tell which version of Keda is running in a given Kubernetes cluster. This is really useful when managing multiple clusters to do spot check of which version of Keda is running.

LGTM, nice addition - Thanks! Would you mind adding a test for it please, or do we not have tests for metrics yet @JorTurFer?

pedro-stanaka · 2023-06-01T07:26:25Z

I am on the process of adding a test, that is why I left on draft. But running e2e tests on my computer is a PITA. Working on it.

The test can be added here: https://github.com/kedacore/keda/blob/main/tests/sequential/prometheus_metrics/prometheus_metrics_test.go

You can just run a specific test, if you have k8s cluster ready with the KEDA build deployed: https://github.com/kedacore/keda/tree/main/tests#specific-test

pkg/prommetrics/prommetrics.go

Can I change somehow the deploy to use the an image built from my version of the code? Otherwise the test will never pass, since it is running against ghcr.io/kedacore/keda:main

you can run make publish && make deploy just change the image/registry in the Makefile. These commands will build and deploy KEDA on your cluster. Then just run this test.

I have some additional thoughts :)

Can one of the maintainers enqueue another e2e run? cc @zroubalik @JorTurFer

Thanks!

@JorTurFer Any thoughts why e2e tests is still pending?

We should also document the metric:
