use tag@digest for the image with kustomize

[UpGurSyns]

I use images with tags(7 digit git commit head) while building them and push them onto GAR.
In the kustomization file for the application:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

resources:
  - deployment.yaml

commonLabels:
  app.kubernetes.io/name: hello-world
  environment: dev

images:
  - name: hello-world
    newName: asia-northeast1-docker.pkg.dev/<project>/test-gar/helloworld
    newTag: "3abcd13@sha256:sha256:bc9434c3014388cb1d8ce8671fb668ff95a6122de26cc70ac324f9ac985c782a9"

In the ImageUpdater CR:

spec:

  # Global update settings (can be overridden per application)
  commonUpdateSettings:
    updateStrategy: "newest-build"
  applicationRefs:

    - namePattern: "frontend-*"
      labelSelectors:
        matchLabels:
          app.kubernetes.io/part-of: fe-dev

      # Images to track for matched applications
      images:
        # hello-world
        - alias: "hello-world"
          imageName: "asia-northeast1-docker.pkg.dev/<project>/test-gar/helloworld"
          manifestTargets:
            kustomize:
              name: hello-world

With this setup, the image-updater is updating the image to just to the tag, while I need the entire tag@digest. Please note I'm not using the semver versioning nor latest tag but use tags based on git commit hash.

Is there a way to achieve this currently using argocd-image-updater?

Hello,
Have you considered using digest update strategy?
