Flux doesn't redeploy when local Helm charts changes

[itai-spiritt]

My project is built from multiple helm resources (charts) locally (git repo).
I have multiple HelmReleases that depend on these local charts.
I have configured Flux to listen to changes in the Kustomization path, and the charts are in a different path.

• charts
  • app-stack
    • deployment.yaml
    • ingress.yaml
    • ...
• clusters
  • test
    • apps
      • a.yaml
      • b.yaml
      • ...

a.yaml

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
spec:
  interval: 1m
  chart:
    spec:
      chart: ./charts/app-stack
      sourceRef:
        kind: GitRepository
        name: flux-system
        namespace: flux-system
values:
  ...

gotk-sync.yaml

apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  name: flux-system
  namespace: flux-system
spec:
  interval: 1m0s
  path: ./clusters/test
  prune: true
  sourceRef:
    kind: GitRepository
    name: flux-system

How can I trigger a redeploy when changing my charts (files in charts/app-stack)?
I am trying to force the update by adding an arbitrary value in the apps yaml (a.yaml) but nothing happens.

You need to set chart.reconcileStrategy to Revision, docs https://fluxcd.io/flux/guides/helmreleases/#release-when-a-source-revision-changes-for-git-and-cloud-storage
