Update HelmRelease on git tag creation

[jpellizzari]

I have a use case where we want our devs to create a tag for their infra changes to deploy to production. For example, they might change some values for their service, which will auto-deploy to pre-production on merge to main. But for prod, we want to the operation of creating a tag to trigger the change.

Has anyone achieved this or a similar workflow in Flux? We have only been able to do this with imperative CLI calls to create a HelmRelease manually.

If you use an OCIRepository for your helm charts (https://fluxcd.io/flux/guides/helmreleases/#oci-repository), you can combine it with an ImageUpdateAutomation:

Helm docs for OCI repositories: https://helm.sh/docs/topics/registries/

Thanks! I will give that a try and report back
