A way to specify OCI HelmChart version as a digest

[peter-facko]

Hello,

I am using a HelmChart from an OCI HelmRepository. Is there a way to pin the exact chart artefact with a digest?

In Helm docs, there is a documented way to install a Helm Chart with a digest here: https://helm.sh/docs/topics/registries/#installing-charts-with-digest.

You can do this if you migrate to OCIRepository: https://fluxcd.io/flux/components/source/ocirepositories/#digest-example

Note: HelmRepository with type oci is in maintenance mode. For improved support with OCI charts you need to switch to OCIRepository: https://fluxcd.io/flux/components/source/helmrepositories/#type

The Google free AI search nails this:

apiVersion: source.toolkit.fluxcd.io/v1
kind: OCIRepository
metadata:
  name: my-chart-source
  namespace: default
spec:
  interval: 10m
  url: oci://ghcr.io/your-org/charts/my-chart
  ref:
    digest: sha256:your-full-sha256-digest-here
---
apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: my-app
  namespace: default
spec:
  interval: 10m
  chartRef:
    kind: OCIRepository
    name: my-chart-source
  values:
    replicaCount: 2
