Thanks for this. Although what about doing it this way (below)? For example, you can keep the .tpl logic that is checking the kubernetes versions? I think most people just want to overide the repository? and not maintain the specific container versions, because that really depends on the kubernetes cluster version?

{{- define "csi-isilon.attacherImage" -}}
  {{- if eq .Capabilities.KubeVersion.Major "1" }}
    {{- if and (ge (trimSuffix "+" .Capabilities.KubeVersion.Minor) "21") (le (trimSuffix "+" .Capabilities.KubeVersion.Minor) "28") -}}
      {{- print .Values.images.helperRepository "/csi-attacher:v4.3.0" -}}
    {{- end -}}
  {{- end -}}
{{- end -}}

And then in the values you can just set the registry like this:

  metadataretriever:
    image: /csi-metadata-retriever:v1.4.0

    # image: Image to use for dell-csi-replicator. This shouldn't be changed
    # Allowed values: string
    # Default value: None
    image: /dell-csi-replicator:v1.6.0

images:
  # "driver" defines the container image, used for the driver container.
  driverRepository: dellemc
  helperRepository: registry.k8s.io/sig-storage
