image-reflector-controller cannot pull image list

[ccodreanu]

We upgraded from 0.19.2 to 0.19.3 and our Image Policies are getting spammed with:

image-reflector-controller  Cannot determine latest tag for policy: version list argument cannot be empty

while Image Repositories show:

image-reflector-controller  GCR authentication failed: registry provider not configured for login

We see this happening on images like k8s.gcr.io/sig-storage/snapshot-validation-webhook which do not require auth to be pulled.

Image Repo and Policy:

---
apiVersion: image.toolkit.fluxcd.io/v1beta1
kind: ImageRepository
metadata:
  name: snapshot-validation-webhook
spec:
  image: k8s.gcr.io/sig-storage/snapshot-validation-webhook
  interval: 24h
---
apiVersion: image.toolkit.fluxcd.io/v1beta1
kind: ImagePolicy
metadata:
  name: snapshot-validation-webhook
spec:
  imageRepositoryRef:
    name: snapshot-validation-webhook
  policy:
    semver:
      range: ">=5.0.0"

Hi, thanks for reporting the issue. We did some refactoring of the registry code in the last release and looks like we didn't had any coverage for this scenario. I've created #290 to fix this issue and also added a test for it so that we don't have this bug again in the future.

Image reflector controller v0.19.4 is available now https://github.com/fluxcd/image-reflector-controller/pkgs/container/image-reflector-controller/29796368?tag=v0.19.4 . You can give it a try.
