Sorry for the Delay. Following up:

I set up a values.yaml with the following change:

...
operator:
  replicaCount: 1
  image:
    repository: ghcr.io/undistro/zora/operator
    tag: "feat-multi-platform-support"
    pullPolicy: IfNotPresent
...

But got the following error:

$ helm install zora -n zora-system -f values.yaml undistro/zora --wait
Error: INSTALLATION FAILED: failed post-install: pod zora-saas-install-hook failed

Looking at the pods got the following:

$ kubectl -n zora-system get pod -o wide

The logs for both pods:

$ kubectl -n zora-system logs -f zora-saas-install-hook
exec /bin/sh: exec format error

$ kubectl -n zora-system logs -f zora-operator-65fb445f99-m8746 -c manager

Conclusion:

The architecture change is working like a charm and the post hook looks like to be another issue that I will investigate.
I think you can merge and thanks for work.
🙇

I have figured out the issue with the hook, the image radial/busyboxplus:curl does not support arm64 architecture.

In this pull request #204 I have changed it to curlimages/curl:7.88.1 that supports arm64 and is rootless. (https://hub.docker.com/r/curlimages/curl/tags)

Be free to use or build another one.

Thank you @wsilva
Good catch about the helm hook image!
I'm closing this PR so we can consider yours (#204).
