Version v0.3.48 of the kraan-controller helm chart includes the new OCIRepository CRD released with v2.6 of Flux. This new resource points to a single artifact in a registry and continuously pulls each new digest as the artifact is overwritten.

Below is an example of the OCIRepository kind:

---
apiVersion: source.toolkit.fluxcd.io/v1
kind: OCIRepository
metadata:
  name: podinfo
  namespace: default
spec:
  interval: 5m0s
  url: oci://ghcr.io/stefanprodan/manifests/podinfo
  ref:
    tag: latest

With Flux v2.6, digest pinning allows you to choose the image digest to pull from the registry. See the following example:

---
apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: my-app
  namespace: apps
spec:
  values:
    image:
      repository: docker.io/my-org/my-app
      tag: latest
      digest: sha256:ec0119...
