[kafka] Disable noisy alerts - #1488
Conversation
The alerts deployed with the Kafka Strimzi operator are noisy and not useful, when a given namespace does not deploy any kafka clusters. This patch removes them. ```release-note [kafka] Disable useless alerts for Kafka which fire when not called for, e.g. when Kafka isn't deployed. ``` Signed-off-by: Timofei Larkin <[email protected]>
Summary of ChangesHello Timofei Larkin (@lllamnyp), I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request addresses an issue where Kafka Strimzi operator alerts were generating excessive noise in environments not actively running Kafka clusters. By disabling the alert deployment mechanism, the change aims to reduce irrelevant notifications and improve the clarity of monitoring signals, ensuring alerts are only triggered when genuinely applicable.

Code Review
This pull request disables noisy Kafka alerts by commenting out the Helm template that generates them. While this is effective, a more flexible approach would be to introduce a feature flag in values.yaml to control the deployment of these alerts. I've added a suggestion to implement this, which would make the chart more configurable for users who might want to enable these alerts in the future.

Instead of commenting out the entire file, it would be more flexible and idiomatic for a Helm chart to introduce a feature flag in values.yaml to control whether these alerts are deployed. This allows users of the chart to easily enable them if needed, without modifying the chart's source code.
I suggest adding a value like alerts.enabled to your values.yaml (defaulting to false to keep the noisy alerts disabled) and then wrapping the content of this template in a conditional block.
{{- if .Values.alerts.enabled }}
{{- $files := .Files.Glob "alerts/*.yaml" -}}
{{- range $path, $file := $files }}
---
# from: {{ $path }}
{{ toString $file }}
{{- end }}
{{- end }}
