Override terminationGracePeriodSeconds does not work

[Andreik8s]

I have an app running on GKE, deployed as HelmRelease with flux. I want to change the terminationGracePeriodSeconds from the default value 30 to less like 20. But, I'd like to do it from the HelmRelease spec file. I have added it at the HelmRelease spec, then to the pod and deployment section but it does not change.

According to the docs https://fluxcd.io/docs/components/helm/helmreleases/#values-overrides you say is possible to do it via values but this also does not work.

My spec looks like:

spec:
  releaseName: name-api
  chart:
    git: git@gitlab link to our chart which is a monochart/template
    path: "."
    ref: v1.0.0
  values:
    terminationGracePeriodSeconds: 20
    nameOverride: "name-api"
    fullnameOverride: "name-api"
    image: our custom image
    imagePullSecrets:
    - docker-registry
    replicaCount: 1

Any idea why the values does not help?

I have also tested this on minikube with the same HelmRelease and still does not possible to override.

Thanks

Have you tested this with Helm CLI, does it actually changes the output if you run helm template?

[Andreik8s]

In our chart/template I do not use the terminationGracePeriodSeconds, the default is picked up from K8s.

Not sure what you mean with the helm template, never used and not sure what to check/do.

Should I set it in the chart/template level?

Yes, Flux uses the HelmRelease.spec.values in the same way helm install/upgrade/template --values=values.yaml does it. If terminationGracePeriodSeconds is not a Helm var it will not work.
