AlertManager CRD

[mjallday]

Please let me know if there's an existing issue, I did a search but didn't see anything related to this yet.

I'm a big fan of the PrometheusRule CRD and am looking for something similar to configure AlertManager to allow declaring rules for alerting via a CRD.

• https://github.com/prometheus-operator/prometheus-operator/search?q=PrometheusRule

I'm not sure of the state of the Cortex Project yet but am curious if there has been any development on this yet or if not, where would be a suitable place for this logic to live?

This looks like something to build on top of Cortex (eg. automation to generate alertmanager config based on CRD) and not something to do within Cortex. I think supporting Kubernetes CRDs is out of the scope of Cortex.

i see the other gh repo on the cortex org is a helm chart which is kubernetes specific. is there interest in doing something similar for k8s CRDs? or making it part of the helm chart?

i'm not super familiar with how the project sees these kinds of additions so looking for advice. we might be able to assist in development since we want a gitops driven deployment for cortex alerts

We have the next Cortex community call scheduled for 1st April. If it's not too late, I would suggest you to join it and discuss it in that occasion, otherwise I can try to get the attention of other Cortex maintainers on this, since I don't have a quick answer / opinion.

For what it's worth we are in the same boat as you and decided to not use Cortex's Alertmanager altogether and use the one from the Prometheus Operator so we could use the CRDs. It's not ideal and I would like to use the Cortex one, but it just doesn't suit our needs.

Thanks, are these the relevant details for the Cortext community?

i can't seem to see an event scheduled for 1st april. this google group seems a little dead so i'm guessing there's somewhere better to see this @pracucci

We're also looking for similar functionality and this is the closest thing I could find

Cool, we just open sourced our version https://github.com/verygood-ops/open-metrics-multi-tenancy-kit

open-metrics-multi-tenancy-kit implements multi-tenancy for metrics collection and rules management in Cortex environments, configured via OpenMetricsRule Kubernetes resource.
