[kube-prometheus-stack] Lack of Fine-Grained Control for Modifying Individual Alerts in PrometheusRules

[varunrr]

Is your feature request related to a problem ?

The kube-prometheus-stack Helm chart does not currently expose fine-grained control for modifying or adding labels to individual alerts within existing PrometheusRules. Users who need to customize or extend existing alerts (such as adding custom labels to specific alerts) must manually edit the PrometheusRule manifests or create an entirely new rule to replace the existing one.

Describe the solution you'd like.

Need a templating change which will enable us to add labels not only to a group of alerts but to an individual alert too.

Describe alternatives you've considered.

We are currently disabling predefined alert and creating a copy with additional labels.

Additional context.
