Alert with namespace regex

[sov-msaeed]

Hi, quick question, is it possible to add regex in the namespace field in the Alert resource https://fluxcd.io/flux/components/notification/alerts/ I want to have Alerts of all helmreleases for namespaces contains prod, would that work ?

Namespace wildcard is not supported

I am not sure what happened but it seems that my comments and your previous comment were deleted.

I asked if i can use this inclusionList as workaround.

if not possible, is this the correct way to do multiple ns ?

---
apiVersion: notification.toolkit.fluxcd.io/v1beta3
kind: Alert
metadata:
  name: slack
  namespace: flux-system
spec:
  providerRef:
    name: slack-bot
  eventMetadata:
    summary: Cluster addons impacted
    env: prod
    cluster: my-cluster
    region: us-east-2
  eventSeverity: error
  eventSources:
    - kind: HelmRelease
      name: '*'
      namespace: "prod-1"
    - kind: HelmRelease
      name: '*'
      namespace: "prod-2"

inclusionList is for filtering based on the message, namespace is not supported

ok thanks, would that work ? or i have to create Alert per namespace ?

Yes, that works, as mentioned in the docs for event source: https://fluxcd.io/flux/components/notification/alerts/#select-all-objects-in-a-namespace

Unless the cluster administrator (possibly you) has set the binary flag --no-cross-namespace-refs:

https://fluxcd.io/flux/components/notification/alerts/#disable-cross-namespace-selectors

I guess you didn't
